Exploring patients' needs and expectations for information on sexual dysfunction after rectal cancer treatment: A qualitative study.

AIM: Sexual dysfunction is an important, and often overlooked, sequela of rectal cancer treatment with significant implications for patients' quality of life. The aim of this study was to explore patients' information needs regarding sexual health after rectal cancer treatment and their experiences accessing information on sexual dysfunction throughout the cancer care continuum. The secondary aim was to explore surgeons' perspectives on patients' information needs and gain insight into their experiences providing information on sexual health following rectal cancer surgery. METHOD: A qualitative study was conducted using semistructured interviews with 10 rectal cancer survivors and six colorectal surgeons from a Canadian tertiary care institution. Transcribed interviews were coded independently by two researchers and thematic analysis was performed. RESULTS: Analysis of patient interviews revealed that patients had limited knowledge of sexual dysfunction symptoms following rectal cancer treatment and received inadequate information on sexual dysfunction from their treating medical team. Patients expressed the desire to receive information on sexual dysfunction in different formats, especially before the start of treatment. The surgeon interviews revealed that colorectal surgeons faced challenges when informing patients about sexual dysfunction. Surgeons did not routinely provide information on sexual dysfunction to all patients; however, they felt that patients should receive high-quality information on sexual dysfunction, both before and after treatment. CONCLUSION: Patients' information needs related to sexual dysfunction after rectal cancer treatment were inadequately met. High-quality informational resources are needed to facilitate communication between patients and physicians and improve patients' understanding of sexual dysfunction.

Timing of readmissions for complications following emergency colectomy: follow-up beyond post-operative day 30 matters.

BACKGROUND AND PURPOSE: Emergency colectomies are associated with a higher risk of complications compared to elective ones. A critical assessment of complications occurring beyond post-operative day 30 (POD30) is lacking. This study aimed to assess the readmission rate and factors associated with readmission 6-months following emergency colectomy. METHODS: A retrospective cohort study of adult patients who underwent emergency colectomy (2010-2018) was performed using the Nationwide Readmissions Database. The cohort was divided into two groups: (i) no readmission and (ii) emergency readmission(s) for complications related to colectomy (defined using ICD-9/10 codes). Readmissions were categorized as either "early" (POD0-30) or "late" (> POD30). Differences between groups were described and multivariable regression controlling for relevant covariates defined a priori were used to identify factors associated with timing of readmission and cost. RESULTS: Of 141,481 eligible cases, 13.22% (n = 18,699) were readmitted within 6-months of emergency colectomy for colectomy-related complications, 61.63% of which were "late" readmissions (> POD30). The most common reasons for "late" readmission were for bleeding, gastrointestinal, and infectious complications (20.80%, 25.30%, and 32.75%, respectively). On multiple logistic regression, female gender (OR 1.12; 95%CI 1.04-1.21), open procedures (OR 1.12, 95%CI 1.011-1.24), and sigmoidectomies (OR 1.51, 95%CI 1.39-1.65, relative to right hemicolectomies) were the strongest predictors of "late" readmission. On multiple linear regression, "late" readmissions were associated with a $1717.09 USD (95%CI $1717.05-$1717.12) increased cost compared to "early" readmissions. DISCUSSION: The majority of colectomy-related readmissions following emergency colectomy occur beyond POD30 and are associated with cases that are of overall higher morbidity, as well as open sigmoidectomies. Given the associated increased cost of care, mitigation of such readmissions by close follow-up prior to and beyond POD30 is advisable.

Incidence and Factors Associated With Mental Health Disorders in Patients With Rectal Cancer Post-Restorative Proctectomy.

BACKGROUND: Most patients with rectal cancer experience bowel symptoms post-restorative proctectomy. The incidence of mental health disorders post-restorative proctectomy and its association with bowel symptoms are unknown. OBJECTIVES: This study aimed 1) to describe the incidence of mental health disorders in patients who underwent restorative proctectomy for rectal cancer and 2) to study the association between incident mental health disorders and bowel dysfunction after surgery. DESIGN: This retrospective cohort study used the Clinical Practice Research Datalink and Hospital Episode Statistics databases. SETTINGS: The databases were based in the United Kingdom. PATIENTS: All adult patients who underwent restorative proctectomy for a rectal neoplasm between 1998 and 2018 were included. MAIN OUTCOME MEASURES: The primary outcome was an incident mental health disorder. The associations between bowel, sexual, and urinary dysfunctions and incident mental health disorders were studied using Cox proportional hazard regression models. RESULTS: In total, 2197 patients who underwent restorative proctectomy were identified. Of 1858 patients without preoperative bowel, sexual, or urinary dysfunction, 1455 had no preoperative mental health disorders. In this cohort, 466 patients (32.0%) developed incident mental health disorders following restorative proctectomy during 6333 person-years of follow-up. On multivariate Cox regression, female sex (adjusted HR 1.30; 95% CI, 1.06-1.56), metastatic disease (adjusted HR 1.57; 95% CI, 1.14-2.15), incident bowel dysfunction (adjusted HR 1.41, 95% CI, 1.13-1.77), and urinary dysfunction (adjusted HR 1.57; 95% CI, 1.16-2.14) were found to be associated with developing incident mental health disorders post-restorative proctectomy. LIMITATIONS: This study was limited by its observational study design and residual confounding. CONCLUSIONS: Incident mental health disorders after restorative proctectomy for rectal cancer are common. The presence of bowel and urinary functional impairment significantly increases the risk of poor psychological outcomes among rectal cancer survivors.

Extended versus limited mesenteric excision for operative Crohn's disease: 30-Day outcomes from the ACS-NSQIP database.

PURPOSE: Recent studies have suggested that extended mesenteric excision (ME) may reduce surgical reintervention in Crohn's Disease (CD), but there remains clinical concerns regarding potential peri-operative morbidity. This retrospective study compares 30-day perioperative morbidity between limited and extended ME in segmental colectomies for CD. METHODS: Using the American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) colectomy-specific database, all patients with CD undergoing segmental colectomy for non-malignant indications between 2014-2019 were included. A lymph node harvest of 12 or more nodes was used as a surrogate for extended ME. The primary outcome was NSQIP major morbidity. Secondary outcomes included abdominal complications and perioperative bleeding. RESULTS: Of 3,709 patients included from the ACS-NSQIP database, 3,087 underwent limited ME and 622 underwent extended ME. On univariate analysis, those with limited mesenteric excision were less likely to be anemic (46.1% vs 55.0%, p < 0.001) and have undergone an open surgery (44.7% vs 34.7%, p < 0.001). On univariate comparison of limited and extended ME, there was no significant difference in major morbidity. On multiple logistic regression, controlling for age, sex, BMI, smoking, preoperative sepsis, preoperative anemia, surgical approach, emergency surgery, stoma creation, bowel preparation, and immunosuppression, the extent of ME was not an independent predictor of NSQIP major morbidity (OR 1.1, 95% CI 0.84-1.44). Likewise, the extent of ME was not associated with an increase in abdominal complications (OR 0.95, 95% CI 0.76-1.19) or post-operative bleeding (OR 1.89, 95% CI 0.75-1.53). CONCLUSION: Extended ME for CD was not associated with an increase in 30-day perioperative major morbidity.

Emergency colectomies in the NOAC era: a nationwide analysis demonstrating increased complications.

BACKGROUND: The use of Non-vitamin K antagonist oral anticoagulants (NOAC) has increased substantially since their introduction in 2010. The lack of readily available reversal agents poses a challenge in perioperative management. The aim of this study was to evaluate the impact of NOACs on the outcomes of emergency colectomies. METHODS: All adult patients on long-term anticoagulation who underwent emergency colectomies were identified from the Nationwide Inpatient Sample (NIS) database from 2002 to 2018. Long-term anticoagulation was defined using ICD-9/10 codes. Two cohorts were compared: anticoagulated patients in the pre-NOAC era (2002-2010) and anticoagulated patients in the NOAC era (2010-2018). Outcomes of interest were postoperative surgical complications, mortality and need for transfusion. RESULTS: Of 13,218 patients on long-term anticoagulation, 3,264 patients were treated in the pre-NOAC era and 9,954 in the NOAC era. Over the study period, there was a significant increase in the proportion of anticoagulated patients undergoing emergency colectomies (R2 = 0.91). On univariate analysis, anticoagulated patients in the NOAC era were medically more comorbid and had higher rates of postoperative surgical complications (73.3% vs 60.3%, p < 0.001) and mortality (8.2% vs. 6.7%, p = 0.006), but had lower rates of postoperative bleeding (3.5% vs. 4.4%, p = 0.002) and transfusions (38.1% vs. 45.4%, p < 0.001). On multivariable regression, after accounting for clinically significant covariates, anticoagulation in the NOAC era was associated with decreased rates of postoperative bleeding (OR 0.70, 95%CI 0.57-0.88) and transfusions (OR 0.71 95%CI 0.64-0.77) but remained an independent predictor of increased overall postoperative complications (OR 1.26, 95%CI 1.14-1.39). CONCLUSION: Prevalence of long-term anticoagulation in patients undergoing emergency colectomies is increasing. Although associated with lower rates of postoperative bleeding and transfusions, anticoagulation in the NOAC era is associated with higher rates of overall postoperative complications. Evidence-based guidelines for perioperative management of patients on NOACs in the emergency colorectal surgery setting are needed.

Is the Hartmann's procedure for diverticulitis obsolete? National trends in colectomy for diverticulitis in the emergency setting from 1993 to 2018.

BACKGROUND: Historically, Hartmann's procedure (HP) has been the operation of choice for diverticulitis in the emergency setting. However, recent evidence has demonstrated the safety of primary anastomosis (PA) with or without diverting ileostomy. The purpose of this study was to evaluate the trends of, and factors associated with, HP compared to PA in emergency surgery for diverticulitis over 25 years. METHODS: Using the National Inpatient Sample database, we identified adult patients ≥ 18 years old who underwent emergency surgery for diverticulitis (HP or PA) between 1993 and 2018 using ICD-9 and ICD-10 codes. Patients with inflammatory bowel disease, gastrointestinal cancer or who underwent elective diverticulitis surgery were excluded. Trends in HP were analyzed using multivariable linear regression, and factors associated with HP were assessed with multiple logistic regression. RESULTS: Of 499,433 patients who underwent colectomy in the emergency setting for acute diverticulitis, 271,288 (54.3%) had a HP and 228,145 (45.7%) had a PA. Median age was 61 years (IQR: 50-73), 53% were women, and 70.5% were white. The proportion of HP slightly increased over the study period-HP comprised 52.6% of included cases in 1993-98 and 55.2% of cases in 2014-2018 (p = 0.017). Advanced age (reference = 18-44 years; 45-54 years: OR 1.16, 95% CI 1.10-1.22; 55-64 years: OR 1.26, 95% CI 1.20-1.33; 65-74 years: OR 1.33, 95% CI 1.25-1.42; ≥ 75 years: OR 1.51, 95% CI 1.41-1.62), complicated diverticulitis (OR 1.41, 95% CI 1.36-1.46), and severity of illness (reference = minor; moderate: OR 1.46, 95% CI 1.38-1.54; major/extreme: OR 3.43, 95% CI 3.25-3.63) were associated with increased odds of HP. CONCLUSIONS: Over a 26-year period, HP has remained the most performed procedure in the emergency setting for diverticulitis. Future work should focus on knowledge translation with a possible change in practice as more randomized controlled trials provide support for PA.

Bowel stimulation before loop ileostomy closure to reduce postoperative ileus: a multicenter, single-blinded, randomized controlled trial.

INTRODUCTION: The objective of this study was to evaluate the impact of preoperative bowel stimulation on the development of postoperative ileus (POI) after loop ileostomy closure. METHODS: This was a multicenter, randomized controlled trial (NCT025596350) including adult (≥ 18 years old) patients who underwent elective loop ileostomy closure at 7 participating hospitals. Participants were randomly assigned (1:1) using a centralized computer-generated sequence with block randomization to either preoperative bowel stimulation or no stimulation (control group). Bowel stimulation consisted of 10 outpatient sessions within the 3 weeks prior to ileostomy closure and was performed by trained Enterostomal Therapy nurses. The primary outcome was POI, defined as an intolerance to oral food in the absence of clinical or radiological signs of obstruction, on or after postoperative day 3, that either (a) required nasogastric tube insertion; or (b) was associated with two of the following: nausea/vomiting, abdominal distension, or the absence of flatus. RESULTS: Between January 2017 and November 2020, 101 patients were randomized, and 5 patients never underwent ileostomy closure; thus, 96 patients (47 stimulated vs. 49 control) were analyzed according to a modified intention-to-treat protocol. Baseline characteristics were well balanced in both groups. The incidence of POI was lower among patients randomized to stimulation (6.4% vs. 24.5%, p = 0.034; unadjusted RR: 0.26, 95% CI 0.078-0.87). Stimulated patients also had earlier median time to first flatus (2.0 days (1.0-2.0) vs. 2.0 days (2.0-3.0), p = 0.025), were more likely to pass flatus on postoperative day 1 (46.8% vs. 22.4%, p = 0.022), and had a shorter median postoperative hospital stay (3.0 days (2.0-3.5) vs. 4.0 days (2.0-6.0), p = 0.003). CONCLUSIONS: Preoperative bowel stimulation via the efferent limb of the ileostomy reduced POI after elective loop ileostomy closure.

Patient and surgeon preferences for early ileostomy closure following restorative proctectomy for rectal cancer: why aren't we doing it?

BACKGROUND: Early ileostomy closure (EIC), ≤ 2 weeks from creation, is a relatively new practice. Multiple studies have demonstrated that this approach is safe, feasible, and cost-effective. Despite the demonstrated benefits, this is neither routine practice, nor has it been studied, in North America. This study aimed to assess patient and surgeon perspectives about EIC. METHODS: A mixed-methods, cross-sectional study of patients and surgeons was performed. Rectal cancer survivors from a single institution who underwent restorative proctectomy with diverting loop ileostomy and subsequent closure within the last 5 years were contacted. North American surgeons with high rectal cancer volumes (> 20 cases/year) were included. Surveys (patients) and semi-structured interviews (surgeons) were conducted. Analysis employed descriptive statistics and thematic analysis, respectively. RESULTS: Forty-eight patients were surveyed (mean age 65.1 ± 11.8 years; 54.2% male). Stoma closure occurred after a median of 7.7 months (IQR 4.8-10.9) and 50.0% (24) found it "difficult" or "very difficult" to live with their stoma. Patients considered improvement in quality of life and quicker return to normal function the most important advantages of EIC, whereas the idea of two operations in two weeks being too taxing on the body was deemed the biggest disadvantage. Most patients (35, 72.9%) would have opted for EIC. Surgeon interviews (15) revealed 4 overarching themes: (1) there are many benefits to EIC; (2) specific patient characteristics would make EIC an appropriate option; (3) many barriers to implementing EIC exist; and (4) many logistical hurdles need to be addressed for successful implementation. Most surgeons (12, 80.0%) would "definitely want to participate" in a North American randomized-controlled trial (RCT) on EIC for rectal cancer patients. CONCLUSIONS: Implementing EIC poses many logistical challenges. Both patients and surgeons are interested in further exploring EIC and believe it warrants a North American RCT to motivate a change in practice.

Understanding the Burden of Colorectal Adenomas in Patients Younger Than 50 Years: A Large Single-Center Retrospective Cohort Study.

BACKGROUND: Colorectal cancer is increasing in young adults. Our understanding of the adenoma-carcinoma sequence in young patients aged <50 years is lacking. The yield obtained by lowering the age of screening colonoscopy remains unclear. OBJECTIVE: The goal of this study was to understand the burden and histology of colorectal polyps in young adults and to explore predictors of adenoma detection in this population. DESIGN: This is a retrospective cohort study. SETTING: Colonoscopies were performed at a single university-affiliated tertiary care center. PATIENTS: This study included adults aged <50 years who underwent a colonoscopy between 2014 and 2019. Patients with inflammatory bowel disease and genetic disorders were excluded. MAIN OUTCOME MEASURES: Adenoma detection rates were analyzed according to age. Predictors of adenoma detection were investigated by multiple logistic regression. RESULTS: A total of 4475 patients were analyzed. The mean age was 40.2 ± 8.0 years, 56.4% were female, and the mean BMI was 26.3 ± 5.5 kg/m2. A family history of colorectal cancer was reported in 23.8% of patients. The overall polyp and adenoma detection rates were 22% and 14%. The majority of polyps were adenomatous (58.9% of all polypectomies) and located in the left colon or rectum (61.4%). The detection rates of adenomas, advanced neoplasias, and adenocarcinomas were highest in patients aged 45 to 49 (19.3%, 4.8%, and 1.3%). On multivariate analysis, variables independently associated with adenoma detection included age (OR 1.08, 95% CI, 1.06-1.1), female sex (OR 1.80, 95% CI, 1.44-2.27), BMI (OR 1.01, 95% CI, 1.01-1.05), and having undergone a diagnostic colonoscopy (OR 1.81, 95% CI, 1.44-2.29). On subgroup analysis of patients aged 45 to 49, the same variables remained associated with adenoma detection except for age. LIMITATIONS: The study was limited due to the retrospective nature with heterogenous data. CONCLUSIONS: Adenoma detection in young adults aged 45 to 49 approaches the current adenoma detection of older adults. Predictors of adenoma detection in these young adults are female gender and BMI, which may help guide colorectal cancer screening guidelines in the future.

Segmental resection of splenic flexure colon cancers provides an adequate lymph node harvest and is a safe operative approach - an analysis of the ACS-NSQIP database.

INTRODUCTION: Fewer than 10% of colon cancers are found at the splenic flexure. A standard surgical approach to these cancers has not been defined. The goal of this study was to compare lymph node harvest and post-operative morbidity between segmental resection and formal left hemicolectomy for splenic flexure colon cancers. METHOD: Patients diagnosed with a splenic flexure cancer were identified from the 2012-2018 ACS-NSQIP colectomy-targeted database. Patients were categorized based on type of surgical resection - left hemicolectomy with colorectal anastomosis or segmental colectomy with colocolonic anastomosis. Demographic, clinicopathologic, and post-operative outcomes were compared between groups. Factors independently associated with lymph node harvest, operative time, and post-operative morbidity were investigated by linear and binomial logistic regression models. RESULTS: A total of 3,049 patients underwent colectomy for a splenic flexure cancer. Of these, 83.6% had a segmental colectomy and 73% were performed by a minimally invasive approach. T- and N-stage did not differ between segmental and left hemicolectomy groups (p = 0.703 and p = 0.429, respectively). Inadequate nodal harvest (< 12 nodes) was infrequent and similar between the two procedures (7.4% vs. 9.1%, p = 0.13). Operative time was significantly shorter for segmental colectomy (213 ± 83.5 min vs. 193 ± 84.1 min, p < 0.0001) and major morbidity was similar between the two surgical techniques (8.4% vs. 8.9%, p = 0.75). After accounting for demographic, clinicopathologic, and operative factors, binomial logistic regression showed that type of procedure was not significantly associated with LN harvest (OR 0.80, 95%CI 0.54-1.17) or major morbidity (OR 1.17, 95%CI 0.36-3.81). However, on linear regression, segmental splenic flexure resection was associated with shorter operative time (estimate 20.29, 95%CI 12.61-27.97, p < 0.0001). CONCLUSION: Splenic flexure resection for colon cancer is associated with an adequate lymph node harvest. Compared to a formal left hemicolectomy, a segmental resection also has a shorter operative time with equivalent post-operative morbidity.

Early discharge after colorectal cancer resection: trends and impact on patient outcomes.

BACKGROUND: Implementation of early discharge in colorectal surgery has been effective in improving patient satisfaction and reducing healthcare costs. Readmission rates following early discharge among colorectal cancer patients are believed to be low, however, remain understudied. The objectives of this study were: (i) to describe trends in early post-operative discharge and the associated hospitalization costs; (ii) to explore patient outcomes and resource utilization following early discharge; and (ii) to identify predictors of readmission following early discharge. METHODS: This was a retrospective cohort study using the Nationwide Readmissions Database. Adult patients admitted with a primary colorectal neoplasm who underwent colectomy or proctectomy between 2010 and 2017 were identified using ICD-9/10 codes. The exposure of interest was early post-operative discharge defined as ≤ 3 days from surgery. Main outcome measures were 30-day readmissions, post-operative complication rates, LOS and cost. RESULTS: In total, 342,242 patients were identified, and of those, 51,977 patients (15.2%) had early discharges. During the study period, the proportion of early discharges significantly increased (R2 = 0.94), from 9.9 to 23.4%, while readmission rates in this group remained unchanged (mean 7.3% ± 0.5). Complications that required bounceback readmission (within 7 days) after early discharge, rather than during index admission, were an independent predictor of longer overall LOS (ß = 0.044, p < 0.001) and higher hospitalization costs (ß = 0.031, p < 0.001). On multiple logistic regression, factors independently associated with bounceback readmission following early discharge were: male gender (OR = 1.47, 95%CI 1.33-1.63); open surgery (OR = 1.37, 95%CI 1.23-1.52); presence of stoma (OR = 1.51, 95%CI 1.22-1.87); transfer to facility or discharge with home health service (OR = 1.53, 95%CI 1.34-1.75); and Medicare/Medicaid insurance (OR = 1.34, 95%CI 1.14-1.57), among others. CONCLUSION: Early post-operative discharge of colorectal cancer patients is increasing despite a lack of improvement in readmission rates and an overall increase in hospitalization costs. Premature discharge of select patients may result in readmissions due to critical complications related to surgery resulting in increased resource utilization.

The impact of delaying colonoscopies during the COVID-19 pandemic on colorectal cancer detection and prevention.

PURPOSE: The COVID-19 pandemic resulted in a partial to total shutdown of endoscopy in many healthcare centers. This study aims to quantify the impact of the reduction in colonoscopies on colorectal cancer (CRC) detection and screening. METHODS: After institutional ethics board approval, the endoscopy database at an academic tertiary-care center in Montreal, Canada, was searched for all colonoscopies performed from during the first wave locally (March-June 2020), and during the ramp up period where endoscopy service resumed (July to August 2020). We compared these periods to the same periods in 2019, the pre-pandemic periods. The indications, CRC and adenoma detection rates, as well as the prioritization of urgent procedures were compared. RESULTS: In the first wave, only 462 colonoscopies were performed, compared to 2515 in the same period in 2019, an 82% reduction. The ramp up period saw 843 colonoscopies performed compared to 1328 in 2019, a 35% reduction. Urgent and inpatient colonoscopies numbers increased (324 (24.8%) vs. 220 (5.7%)) while surveillance and high-risk screening colonoscopies fell (376 (28.8%) vs 1869 (48.6%)). Emergency access to colonoscopy was preserved with a median time to endoscopy of < 1 day (IQR 0,1) in both pandemic periods. During the pandemic periods, there was an absolute reduction in CRC diagnosis of 28, despite the CRC detection per colonoscopy rate increasing slightly in the first wave from 1.7% (44) to 3.9% (18), and in the ramp up period from 2.5% (33) to 3.6% (31). The rate of adenoma detection per colonoscopy did not increase significantly between the pre- and pandemic periods, resulting in reduction in adenoma removal in 723 patients. DISCUSSION: The restriction of access to colonoscopy resulted in a significant reduction in screening and surveillance of high-risk patients, adenomas removed, and CRCs diagnosed. Clinicians and patients will face the oncologic ramifications this the coming years.

Long-term Implications of Persistent Diverticulitis: A Retrospective Cohort Study of 915 Patients.

BACKGROUND: Persistent (or ongoing) diverticulitis is a well-recognized outcome after treatment for acute sigmoid diverticulitis; however, its definition, incidence, and risk factors, as well as its long-term implications, remain poorly described. OBJECTIVE: The purpose of this study was to assess the incidence, risk factors, and long-term outcomes of persistent diverticulitis. DESIGN: This was a retrospective cohort study. SETTINGS: Two university-affiliated hospitals in Montreal, Quebec, Canada were included. PATIENTS: The study was composed of consecutive patients managed nonoperatively for acute sigmoid diverticulitis. INTERVENTION: Nonoperative management of acute sigmoid diverticulitis was involved. MAIN OUTCOME MEASURES: Persistent diverticulitis, defined as inpatient or outpatient treatment for signs and symptoms of ongoing diverticulitis within the first 60 days after treatment of the index episode, was measured. RESULTS: In total, 915 patients were discharged after an index episode of diverticulitis managed nonoperatively. Seventy-five patients (8.2%; 95% CI, 6.5%-10.2%) presented within 60 days with persistent diverticulitis. Factors associated with persistent diverticulitis were younger age (adjusted OR = 0.98 (95% CI, 0.96-0.99)), immunosuppression (adjusted OR = 2.02 (95% CI, 1.04-3.88)), and abscess (adjusted OR = 2.05 (95% CI, 1.03-3.92)). Among the 75 patients with persistent disease, 42 (56.0%) required hospital admission, 6 (8.0%) required percutaneous drainage, and 5 (6.7%) required resection. After a median follow-up of 39.0 months (range, 17.0-67.3 mo), the overall recurrence rate in the entire cohort was 31.3% (286/910). After excluding patients who were managed operatively for their persistent episode of diverticulitis, the cumulative incidence of recurrent diverticulitis (log-rank: p < 0.001) and sigmoid colectomy (log-rank: p < 0.001) were higher among patients who experienced persistent diverticulitis after the index episode. After adjustment for relevant patient and disease factors, persistent diverticulitis was associated with higher hazards of recurrence (adjusted HR = 1.94 (95% CI, 1.37-2.76) and colectomy (adjusted HR = 5.11 (95% CI, 2.96-8.83)). LIMITATIONS: The study was limited by its observational study design and modest sample size. CONCLUSIONS: Approximately 10% of patients experience persistent diverticulitis after treatment for an index episode of diverticulitis. Persistent diverticulitis is a poor prognostic factor for long-term outcomes, including recurrent diverticulitis and colectomy. See Video Abstract at http://links.lww.com/DCR/B593.

Setenta y cinco pacientes (8,2%; IC del 95%: 6,5-10,2%) presentaron diverticulitis persistente dentro de los 60 días. Los factores asociados con la diverticulitis persistente fueron una edad menor (aOR: 0,98, IC del 95%: 0,96-0,99), inmunosupresión (aOR: 2,02, IC del 95%: 1,04-3,88) y abscesos (aOR: 2,05, IC del 95%: 1,03-3,92). Entre los 75 pacientes con enfermedad persistente, 42 (56,0%) requirieron ingreso hospitalario, 6 (8,0%) drenaje percutáneo y 5 (6,7%) resección. Posterior a seguimiento medio de 39,0 (17,0-67,3) meses, la tasa global de recurrencia de toda la cohorte fue del 31,3% (286/910). Después de excluir a los pacientes que fueron tratados quirúrgicamente por su episodio persistente de diverticulitis, la incidencia acumulada de diverticulitis recurrente (rango logarítmico: p <0,001) y colectomía sigmoidea (rango logarítmico: p <0,001) fue mayor entre los pacientes que experimentaron diverticulitis persistente después el episodio índice.

The quality, suitability, content and readability of online health-related information regarding sexual dysfunction after rectal cancer surgery.

AIM: Patients are not well informed about sexual dysfunction after rectal cancer surgery and often turn to the Internet for information. The purpose of this study was to assess online information for patients on sexual dysfunction after rectal cancer surgery. METHODS: An online search of Google, Yahoo and Bing was performed using specific (e.g., rectal cancer surgery and vaginal pain) and general (e.g., rectal cancer surgery and sex) search terms. Inclusion criteria were websites in English, designed for patients, and including content regarding sexual dysfunction after rectal cancer surgery. Websites were assessed for readability (nine standardized tests), quality (DISCERN tool), suitability (Suitability Assessment of Materials tool), and content. RESULTS: Of 5040 websites identified, 99 unique websites met inclusion criteria. Three (3%) websites fulfilled the American Medical Association recommendation of a 6th-grade reading level. Using the DISCERN instrument, two (2%) websites were assigned good/excellent quality, nineteen (19%) referenced their sources of information, and thirty-one (31%) fully discussed the impact of sexual dysfunction on quality of life. Using the SAM instrument, three (3%) websites were classified as highly suitable for rectal cancer patients, sixty-five (66%) were adequate, and thirty-one (31%) were inadequate. With regards to content, nine (9%) websites fully discussed the impact of sexual dysfunction on patients partners and fifty-one (52%) websites did not cover prognosis. CONCLUSION: Online health information available to patients on sexual dysfunction after rectal cancer surgery is suboptimal. Websites are not suitable, lack important content, and are written at too complex a reading level for patients.

Financial and occupational impact of low anterior resection syndrome in rectal cancer survivors.

AIM: The aim of this study was to assess bowel-related financial stress and strain and to evaluate its association with global quality of life. METHOD: This was a retrospective cohort study with cross-sectional follow-up including consecutive patients who underwent restorative proctectomy for neoplastic disease of the rectum at a single university-affiliated hospital in Montreal, Quebec, Canada. Bowel-related financial impact and occupational impact were compared between patients with major low anterior resection syndrome (LARS) and those with minor/no LARS. The association between LARS, bowel-related financial impact and global quality of life (QoL) was then assessed in a multiple logistic regression model. RESULTS: Of 180 eligible rectal cancer survivors who were contacted, 154 completed the questionnaires (response rate 47.1%) at a median follow-up of 57.5 months (interquartile range 34.1-98.1) after proctectomy. Individuals with major LARS reported a higher prevalence of bowel-related financial stress (53.2% vs 5.6%, p < 0.001) and strain (42.2% vs 5.6%, p < 0.001) compared with those with minor/no LARS. Among those who were working preoperatively (n = 100), the majority of participants with major LARS reported an impact of their new bowel function on their ability to work (70.6%), including delayed return to work (44.1%), the need to change schedules (35.3%) or roles (20.6%), and complete long-term medical absence from work (14.7%). On multiple logistic regression, major LARS with financial impact (OR 4.50, 95% CI 1.57-13.77) was associated with low global QoL compared with minor/no LARS. CONCLUSION: Major LARS was associated with considerable financial stress and strain and difficulties in returning to work.

Interactive online informational and peer support application for patients with low anterior resection syndrome: patient survey and protocol for a multicentre randomized controlled trial.

AIM: Low anterior resection syndrome (LARS) refers to a constellation of bowel symptoms that affect the majority of patients following restorative proctectomy. LARS is associated with poorer quality of life (QoL), and can lead to distress, anxiety and isolation. Peer support could be an important resource for people living with LARS, helping them normalize and validate their experience. The aim of this work is to describe the development of an interactive online informational and peer support app for LARS and the protocol for a randomized controlled trial. METHOD: A multicentre, randomized, assessor-blind, parallel-groups pragmatic trial will involve patients from five large colorectal surgery practices across Canada. The trial will evaluate the impact of an interactive online informational and peer support app for LARS, consisting of LARS informational modules and a closed forum for peers and trained peer support mentors, on patient-reported outcomes of people living with LARS. The primary outcome will be global QoL at 6 months following app exposure. The treatment effect on global QoL will be modelled using generalized estimating equations. Secondary outcomes will include patient activation and bowel function as measured by LARS scores. RESULTS: In order to better understand patients' interest and preferences for an online peer support intervention for LARS, we conducted a single institution cross-sectional survey study of rectal cancer survivors. In total, 35/69 (51%) participants reported interest in online peer support for LARS. Age <65 years (OR 9.1; 95% CI 2.3-50) and minor/major LARS (OR 20; 95% CI 4.2-100) were significant predictors of interest in LARS online peer support. CONCLUSION: There is significant interest in the use of online peer support for LARS among younger patients and those with significant bowel dysfunction. Based on results of the needs assessment study, the app content and features were modified reflect patients' needs and preferences. We are now in an optimal position to rigorously test the potential effects of this initiative on patient-centered outcomes using a randomized controlled trial.

Diverting loop ileostomy versus total abdominal colectomy for clostridioides difficile colitis: outcomes beyond the index admission.

INTRODUCTION: Diverting loop ileostomy (DLI) and colonic lavage has emerged as a valid alternative to total abdominal colectomy (TAC) for the surgical management of Clostridioides difficile colitis (CDC). However, little data are available on outcomes beyond the index admission. The objective of this study was to compare post-discharge outcomes between patients who underwent DLI and TAC for CDC. METHODS: Adult patients who underwent DLI or TAC for CDC between 2011 and 2016 were identified from the Nationwide Readmissions Database, and only discharges between January and September in each calendar year were included to allow for a 90-day follow-up period for all cases. Ninety-day overall in-hospital mortality (index admission mortality plus 90-day post-discharge mortality) and 90-day unplanned readmissions were compared. To assess 6-month ileostomy reversal rates, the cohort was then truncated to exclude discharges after June in each calendar year. Multivariate regression was used to adjust for patient demographics and disease severity. RESULTS: In total, 2070 patients were discharged between January and September of each included year: 1486 (71.8%) TAC compared to 584 (28.2%) DLI. Overall in-hospital mortality was higher among patients who underwent TAC (34.5% vs. 27.7%, p = 0.004); however, this association did not remain on multivariate regression (OR 1.14, 95% CI 0.91-1.43). Among the 1434 patients who were discharged alive, the 90-day unplanned readmission rate was similar in both groups (TAC: 26.1% vs. DLI: 23.1%, p = 0.26). After truncating the cohort to those patients discharged alive between January and June of each included year (n = 1016), patients who underwent DLI had a significantly greater 6-month ileostomy reversal rate (26.4% vs. 8.3%, p < 0.001). DLI was independently associated with higher odds of 6-month ileostomy reversal (OR 2.68, 95% CI 1.80-4.00). CONCLUSIONS: In the surgical management of CDC, DLI is associated with equivalent mortality and unplanned readmission, but greater likelihood of 6-month ileostomy reversal, compared to TAC.

Compliance With Preoperative Elements of the American Society of Colon and Rectal Surgeons Rectal Cancer Surgery Checklist Improves Pathologic and Postoperative Outcomes.

BACKGROUND: In 2016, the American Society of Colon and Rectal Surgeons published a rectal cancer surgery checklist composed of the essential elements of preoperative, intraoperative, and postoperative care for patients undergoing rectal cancer surgery. OBJECTIVE: The purpose of this study was to assess whether compliance with preoperative checklist elements was associated with improved pathologic and 30-day postoperative outcomes after rectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: The study involved North American hospitals contributing to the American College of Surgeons National Surgical Quality Improvement Program. PATIENTS: Adult patients who underwent elective rectal cancer surgery from 2016 to 2017 were included. INTERVENTION: The study encompassed checklist compliance with 6 preoperative elements from the checklist. MAIN OUTCOME MEASURES: Pathologic outcomes (circumferential resection margin status, distal resection margin status, and adequate lymph node harvest ≥12), 30-day surgical morbidity, and length of stay were measured. RESULTS: In total, 2217 patients were included in the analysis. Individual compliance with the 6 available preoperative checklist items was variable, including 91.3% for pretreatment documentation of tumor location within the rectum, 86.8% for complete colonoscopy, 84.0% for appropriate preoperative stoma marking, 79.8% for appropriate use of neoadjuvant radiotherapy, 76.6% for locoregional staging, and 70.8% for distant staging. Only 836 patients (37.7%) had all 6 checklist elements complete, whereas 1381 (62.3%) did not. Compared with patients without checklist compliance, patients with checklist compliance were younger (60.0 vs 63.0 y; p < 0.001) but otherwise had similar demographic characteristics. On multivariate regression, checklist compliance was associated with lower odds of circumferential resection margin positivity (OR = 0.47 (95% CI, 0.31-0.71); p < 0.001), higher odds of an adequate lymph node harvest ≥12 (OR = 1.60 (95% CI, 1.29-2.00); p < 0.001), reduced surgical morbidity (OR = 0.78 (95% CI, 0.65-0.95); p = 0.01), and shorter length of stay (ß = -0.87 (95% CI, -1.51 to -0.24); p = 0.007). The association between checklist compliance and reduced odds of circumferential resection margin positivity remained on sensitivity analysis (OR = 0.61 (95% CI, 0.42-0.88); p = 0.009) when adjusting for neoadjuvant radiation. LIMITATIONS: This study was limited by its absence of long-term oncologic data and missing variables. CONCLUSIONS: Compliance with 6 preoperative elements of the American Society of Colon and Rectal Surgeons rectal cancer surgery checklist was associated with significantly improved pathologic outcomes and reduced postoperative morbidity.

El cumplimiento individual de los seis ítems disponibles de la lista de verificación preoperatoria fue variable: 91.3% para la documentación previa al tratamiento de la localización del tumor dentro del recto, 86.8% para colonoscopía completa, 84.0% para el marcado preoperatorio apropiado del sitio de estoma, 79.8% para el uso apropiado de radioterapia neoadyuvante, 76.6 % para estadificación locorregional y 70.8% para estadificación distante. Solo 836 (37.7%) pacientes tenían los seis elementos de la lista de verificación completos, mientras que 1,381 (62.3%) no. En comparación con los pacientes sin cumplimiento de la lista de verificación, los pacientes con cumplimiento de la lista de verificación eran más jóvenes (60.0 vs. 63.0 años, p <0.001), pero por lo demás tenían características demográficas similares. En la regresión multivariada, el cumplimiento de la lista de verificación se asoció con menores probabilidades de positividad en el margen de resección circunferencial (OR = 0.47; IC del 95%: 0.31-0.71, p <0.001), mayores probabilidades de una cosecha adecuada de ganglios linfáticos ≥12 (OR = 1.60, IC 95% 1.29-2.00, p <0.001), menor morbilidad quirúrgica (OR = 0.78, IC 95% 0.65-0.95, p = 0.01) y menor duración de estadía (ß = -0.87, IC 95% -1.51 - - 0.24, p = 0.007). La asociación entre el cumplimiento de la lista de verificación y las probabilidades reducidas de positividad del margen de resección circunferencial se mantuvo en el análisis de sensibilidad (OR = 0.61; IC del 95%: 0.42-0.88, p = 0.009) al ser ajustado con radiación neoadyuvante.Ausencia de datos oncológicos a largo plazo y variables faltantes.El cumplimiento de seis elementos preoperatorios de la lista de verificación de cirugía de cáncer rectal de la Sociedad Americana de Cirujanos de Colon y Recto se asoció con resultados histopatológicos significativamente mejores y una menor morbilidad postoperatoria.

Readmission for Treatment Failure After Nonoperative Management of Acute Diverticulitis: A Nationwide Readmissions Database Analysis.

BACKGROUND: The true incidence of, and risk factors for, readmission for treatment failure after nonoperative management of acute diverticulitis remain poorly understood. OBJECTIVE: The purpose of this study was to describe the incidence and risk factors for readmission for treatment failure after nonoperative management of acute diverticulitis using a large national database. DESIGN: This was a retrospective cohort study. SETTINGS: A representative sample of admissions and discharges from hospitals in the United States captured in the National Readmissions Database were included. PATIENTS: Adult patients (age ≥18 y) admitted with a primary diagnostic of colonic diverticulitis between 2010 and 2015 and who were managed nonoperatively and discharged from hospital alive were included. INTERVENTIONS: Study intervention included nonoperative management, consisting of medical therapy with or without percutaneous drainage. MAIN OUTCOME MEASURES: Readmission for treatment failure (defined as a nonelective readmission for diverticulitis within 90 d of discharge), complicated treatment failure (defined as a treatment failure with complicated diverticulitis), and time-to-treatment failure were measured. RESULTS: In total, 201,384 patients were included. The overall incidence of readmission for treatment failure was 6.6%. Treatment failure was significantly higher among patients with an index episode of acute complicated diverticulitis compared with acute uncomplicated diverticulitis (12.5% vs 5.7%; p < 0.001). The median time-to-readmission for treatment failure was 21.0 days (range, 20.4-21.6 d), and 85% of all readmissions occurred within 60 days of discharge. On multiple logistic regression, factors independently associated with readmission for treatment failure were an index admission of complicated diverticulitis (OR = 2.06 (95% CI, 1.97-2.16)), disposition on discharge (against medical advice: OR = 1.92 (95% CI, 1.66-2.20); home health care arrangements: OR = 1.24 (95% CI, 1.16-1.33)), and immunosuppression (OR = 1.42 (95% CI, 1.28-1.57)), among others. Risk factors for a complicated treatment failure were also described, after an index episode of complicated and uncomplicated diverticulitis. LIMITATIONS: The study was limited by residual confounding from missing covariates and its observational study design. CONCLUSIONS: The incidence of readmission for treatment failure after an episode of diverticulitis managed nonoperatively is 6.6%, and an index episode of complicated diverticulitis is the strongest risk factor for treatment failure.

REINGRESO POR FRACASO DEL TRATAMIENTO DESPUÉS DEL TRATAMIENTO NO QUIRÚRGICO DE LA DIVERTICULITIS AGUDA: UN ANÁLISIS DE LA BASE DE DATOS DE REINGRESOS A NIVEL NACIONAL: La verdadera incidencia y los factores de riesgo para el reingreso por fracaso del tratamiento después de manejo no quirúrgico de la diverticulitis aguda siguen siendo mal definidos.Definir la incidencia y los factores de riesgo de reingreso por fracaso del tratamiento no quirúrgico de la diverticulitis aguda utilizando una base de datos nacional.Estudio de cohorte retrospectivo.Una muestra representativa de ingresos y egresos de hospitales en los Estados Unidos capturados en la base de datos nacional de reingresos hospitalarios.Pacientes adultos (≥18 años) ingresados con un diagnóstico primario de diverticulitis colónica entre 2010-2015, y que fueron tratados de forma no operativa y dados de alta del hospital vivos.Manejo no quirúrgico, que consiste en terapia médica con o sin drenaje percutáneo.Reingreso por fracaso del tratamiento (definido como un reingreso no electivo por diverticulitis dentro de los 90 días despues de ser dados de alta), fracaso del tratamiento complicado (definido como un fracaso del tratamiento con diverticulitis complicada) y el tiempo hasta el tratamiento en casos fracasaados.201.384 pacientes incluidos en total. La incidencia global de reingreso por fracaso del tratamiento fue del 6,6%. El fracaso del tratamiento fue significativamente mayor entre los pacientes con un episodio índice de diverticulitis aguda complicada en comparación con la diverticulitis aguda no complicada (12.5% vs. 5.7%, p <0.001). La mediana del tiempo hasta el reingreso por fracaso del tratamiento fue de 21.0 (20.4 - 21.6) días, y el 85% de todos los reingresos ocurrieron dentro de los 60 días posteriores a ser dados de alta. En la regresión logística múltiple, los factores asociados independientemente con el reingreso por fracaso del tratamiento fueron un índice de admisión de diverticulitis complicada (OR 2.06, IC 95% 1.97-2.16), disposición (de alta en contra del consejo médico: OR 1.92, IC 95% 1.66-2.2; atención médica domiciliaria: OR 1.24, IC 95% 1.16-1.33) e inmunosupresión (OR 1.42, IC 95% 1.28-1.57), entre otros. Los factores de riesgo para un fracaso del tratamiento complicado también se describieron, respectivamente, después de un episodio índice de diverticulitis complicada y no complicada.Covariables faltantes y diseño de estudio observacional.La incidencia de reingreso por fracaso del tratamiento después de un episodio de diverticulitis manejado de forma no operativa es del 6,6%, y un episodio índice de diverticulitis complicada es el factor de riesgo más fuerte para el fracaso del tratamiento.

Family History Is Associated With Recurrent Diverticulitis After an Episode of Diverticulitis Managed Nonoperatively.

BACKGROUND: To date, the impact of family history on diverticulitis outcomes has been poorly described. OBJECTIVE: This study aims to evaluate the association between family history and diverticulitis recurrence after an episode of diverticulitis managed nonoperatively. DESIGN: This is a retrospective cohort study with prospective telephone follow-up. SETTINGS: This study was conducted at 2 McGill University-affiliated tertiary care hospitals in Montreal, Canada. PATIENTS: All immunocompetent patients with CT-proven left-sided diverticulitis who were managed nonoperatively from 2007 to 2017 were included. INTERVENTION: A positive family history for diverticulitis, as assessed by a detailed telephone questionnaire, was obtained. MAIN OUTCOME MEASURES: The primary outcome was diverticulitis recurrence occurring >60 days after the index episode. Secondary outcomes included a complicated recurrence and >1 recurrence (ie, re-recurrence). RESULTS: Of the 879 patients identified in the database, 433 completed the telephone questionnaire (response rate: 48.9%). Among them, 173 (40.0%) had a positive family history of diverticulitis and 260 (60.0%) did not. Compared to patients with no family history, patients with family history had a younger median age (59.0 vs 62.0 years, p = 0.020) and a higher incidence of abscess (24.3% vs 3.5%, p < 0.001). After a median follow-up of 40.1 (17.4-65.3) months, patients with a positive family history had a higher cumulative incidence of recurrence (log-rank test: p < 0.001). On Cox regression, a positive family history remained associated with diverticulitis recurrence (HR, 3.74; 95% CI, 2.67-5.24). Among patients with a positive family history, >1 relative with a history of diverticulitis had a higher hazard of recurrence (HR, 2.93; 95% CI, 1.96-4.39) than patients with only 1 relative with a history of diverticulitis. Positive family history was also associated with the development of a complicated recurrence (HR, 8.30; 95% CI, 3.64-18.9) and >1 recurrence (HR, 2.03; 95% CI, 1.13-3.65). LIMITATIONS: This study has the potential for recall and nonresponse bias. CONCLUSION: Patients with a positive family history of diverticulitis are at higher risk for recurrent diverticulitis and complicated recurrences. See Video Abstract at http://links.lww.com/DCR/B215. LOS ANTECEDENTES FAMILIARES ESTÁN ASOCIADOS CON DIVERTICULITIS RECURRENTE, DESPUÉS DE UN EPISODIO DE DIVERTICULITIS MANEJADA SIN OPERACIÓN: Hasta la fecha, el impacto de los antecedentes familiares en los resultados de la diverticulitis, ha sido mal descrito.Evaluar la asociación entre los antecedentes familiares y la recurrencia de diverticulitis después de un episodio de diverticulitis manejado de forma no operatoria.Estudio de cohorte retrospectivo con seguimiento telefónico prospectivo.Dos hospitales de atención terciaria afiliados a la Universidad McGill en Montreal, Canadá.Todos los pacientes inmunocompetentes con diverticulitis izquierda comprobada por TAC, que fueron manejados sin cirugía desde 2007-2017.Una historia familiar positiva para diverticulitis, según lo evaluado por un detallado cuestionario telefónico.El resultado primario fue la recurrencia de diverticulitis ocurriendo > 60 días después del episodio índice. Resultados secundarios incluyeron una recurrencia complicada y >1 recurrencia (es decir, re-recurrencia).De los 879 pacientes identificados en la base de datos, 433 completaron el cuestionario telefónico (tasa de respuesta: 48,9%). Entre ellos, 173 (40.0%) tenían antecedentes familiares positivos de diverticulitis y 260 (60.0%) no tenían. Comparados con los pacientes sin antecedentes familiares, los pacientes con antecedentes familiares tenían una mediana de edad más joven (59.0 vs 62.0 años, p = 0.020) y una mayor incidencia de abscesos (24.3% vs 3.5%, p < 0.001). Después de una mediana de seguimiento de 40.1 (17.4-65.3) meses, los pacientes con antecedentes familiares positivos tuvieron una mayor incidencia acumulada de recurrencia (prueba de log-rank: p < 0.001). En la regresión de Cox, un historial familiar positivo, permaneció asociado con recurrencia de diverticulitis (HR, 3.74; IC 95%, 2.67-5.24). Entre los pacientes con antecedentes familiares positivos, >1 familiar con antecedentes de diverticulitis, tuvieron mayores riesgos de recurrencia (HR, 2.93; IC 95%, 1.96-4.39) en comparación de los pacientes con solo 1 familiar. La historia familiar positiva también se asoció con el desarrollo de una recurrencia complicada (HR, 8.30; IC 95%, 3.64-18.9) y >1 recurrencia (HR, 2.03; IC 95%, 1.13-3.65).Potencial de recuerdo y sesgo de no respuesta.Los pacientes con antecedentes familiares positivos de diverticulitis tienen un mayor riesgo para diverticulitis recurrente y recurrencias complicadas.
