Mental health disorders as a risk factor in young patients with rectal prolapse.

BACKGROUND: Rectal prolapse (RP) typically presents in the elderly, though it can present in younger patients lacking traditional risk factors. The current study compares medical and mental health history, presentation, and outcomes for young and older patients with RP. METHODS: This is a single-center retrospective review of patients who underwent abdominal repair of RP between 2005 and 2019. Individuals were dichotomized into two groups based on age greater or less than 40 years. RESULTS: Of 156 patients, 25 were < 40. Younger patients had higher rates of diagnosed mental health disorders (80% vs 41%, p < 0.001), more likely to take SSRIs (p = .02), SNRIs (p = .021), anxiolytics (p = 0.033), and antipsychotics (p < 0.001). Younger patients had lower preoperative incontinence but higher constipation. Both groups had low rates of recurrence (9.1% vs 11.6%, p = 0.73). CONCLUSIONS: Young patients with RP present with higher concomitant mental health diagnoses and represent unique risk factors characterized by chronic straining compared to pelvic floor laxity.

Role of Age as a Predictor of Major Complications After Elective Surgery for Ulcerative Colitis.

BACKGROUND: The incidence of ulcerative colitis (UC) in the elderly population is increasing. The aim of this study was to assess the degree to which age and other factors increase the risk of developing major complications in patients undergoing elective surgery for UC. METHODS: Using the ACS-NSQIP database from 2016 to 2020, patients undergoing elective surgery for UC were divided into four categories: younger than 30, 30-49, 50-69, and 70 or older. A composite outcome was created including major complications and multivariable analysis was performed to identify factors associated with composite major complications. RESULTS: 5946 patients diagnosed with ulcerative colitis who underwent elective surgery were included in the analysis. 14.1% of all patients developed a major complication. For patients with UC, factors associated with the development of a major complication were age 50-69 (OR 1.31, P = .034), male sex (OR 1.38, P < .001), Black race (OR 1.47, P = .049), dependent status (OR 2.06, P = .028), hypoalbuminemia (OR 1.92, P < .001), preoperative steroid treatment (OR 1.27, P = .038), preoperative transfusion (OR 1.91, P < .001), open surgical approach (OR 1.44, P = .002), and partial colectomy (OR 1.51, P = .007). Specifically in patients aged 70 or older, hypoalbuminemia (OR 3.20, P < .001) and preoperative transfusion (OR 2.78, P = .019) were associated with a major complication. CONCLUSION: Age is a risk factor for the development of a major complication in UC patients undergoing elective surgery. However, it is not the only risk factor nor is it the one that increases the risk the most.

Outcomes Following Recent and Distant Neoadjuvant Radiation in Rectal Cancer: An Institutional Retrospective Review and Analysis of NSQIP.

BACKGROUND: Neoadjuvant chemoradiotherapy (nCRT) is the standard of care in locally advanced rectal cancer (LARC). However, radiation therapy is thought to increase operative difficulty due to induction of fibrosis. Total neoadjuvant therapy (TNT) protocols increase the time between completion of radiation and surgical resection which may lead to increased operative difficulty and complications. METHODS: A single institution retrospective review of patients ≥18 years with LARC undergoing nCRT from 2015 to 2022. Patients were dichotomized in 2 cohorts: <90 days from radiation to surgery (recent radiation), and ≥90 days from radiation to surgery (distant radiation). Institutional data was compared to National Surgical Quality Improvement Program (NSQIP) rectal cancer data from 2016 to 2020. Outcomes included intraoperative complications, 30-day morbidity, and oncologic outcomes. RESULTS: One hundred forty-six institutional patients included, 120 had recent radiation, 26 had distant radiation. Thirty-day morbidity and intraoperative complications did not differ. There was greater radial margin positivity (7% vs. 24%), fewer lymph nodes harvested (17 ± 5 vs. 15 ± 6), and a lower rate of complete mesorectal dissection (88% vs. 65%,) in distant radiation patients 3059 patients were included in NSQIP analysis, 2029 completed radiation <90 days before surgery and 1030 without radiation 90 days before surgery. Patients without radiation 90 days preoperatively had more radial margin positivity (9.2% vs. 4.6%), organ space infection (8.6% vs. 6.4%), and pneumonia (2.2% vs. 0.9%). CONCLUSION: The present study suggests that increased time between radiation and surgery results in more challenging dissection with less complete mesorectal dissection and increased radial margin positivity without increasing technical complications.

Magnetic resonance imaging accuracy in staging early and locally advanced rectal cancer.

INTRODUCTION: Magnetic Resonance Imaging (MRI) is the standard pretreatment staging in patients with rectal cancer. Accurate tumor staging is paramount to determining the appropriate treatment course for patients diagnosed with rectal cancer. The current study aims to re-evaluate the accuracy of pre-operative MRI in staging of both early and locally advanced rectal cancer following completion of neoadjuvant therapy (NAT) compared to the pathologic stage. METHODS: A retrospective review of patients treated for rectal cancer between 2015 and 2020 at a single academic institution. All patients underwent rectal cancer protocol MRIs before surgical resection. Analysis was carried out in two groups: early rectal cancer: T1/2 N0 tumors with upfront surgical resection (N = 40); and locally advanced disease: T3 or greater or N+ disease receiving NAT, with restaging MRI following NAT (n = 63). RESULTS: 103 patients were included in analysis. MRI accuracy in early tumors was 35% ICC = 0.52 (95% CI 0.25-0.71) T stage and 66% ICC = 0 (95% CI -0.24, 0.29) for 29 patients with nodal data for N stage. There was 28% understaging of T2 tumors and 34% understaging of N0 stage by MRI. Post NAT MRI had 44% accuracy ICC = 0.57 (95% CI -0.15-0.20) T stage and 60% accuracy ICC = 0.32 (95% CI 0.08-0.52) N stage. Tumor invasion was overstaged on MRI: 40% T2, 29% T3, 90% T4. Nodal inaccuracy was due to overstaging, 61% N1, 90% N2. CONCLUSIONS: In locally advanced rectal cancer MRI overstaged tumors, this could be due to the continued effect of NAT from MRI to resection. This overstaging is of little clinical significance as it doesn't alter the treatment plan, except in cases of complete clinical response. In early rectal cancer, MRI had limited accuracy compared to pathology, understaging a quarter of patients who would benefit from NAT before surgery. Other adjunct imaging modalities should be considered to improve accuracy in staging early rectal cancer and consideration of complete response and enrollment in watch and wait protocols.

Impact of neoadjuvant chemotherapy for locally advanced colon cancer on postoperative complications.

PURPOSE: Although not considered standard therapy, neoadjuvant chemotherapy (NAC) is an encouraging alternative for selected patients with locally advanced colon cancer (LAC). The aim of this study was to compare 30-day postoperative outcomes between patients undergoing upfront surgery and those undergoing NAC for LAC. METHODS: Using the ACS-NSQIP data from 2016 to 2020, 11,498 patients with LAC were divided into those who underwent upfront colectomy (96.2%) and those who received NAC (3.8%). The primary outcome was a composite outcome encompassing 30-day major postoperative complications. Propensity score matched (PSM) analysis and multivariable logistic regression were performed. RESULTS: After PSM analysis, there was no statistically significant difference in the development of a major complication. NAC was not significantly associated with the primary outcome. Risk factors for postoperative complications were T4 stage, older age, male sex, black race, smoking, dependent status, severe COPD, hypoalbuminemia, and preoperative transfusion. Laparoscopic and robotic surgery was protective. CONCLUSION: NAC did not increase the odds of developing a major complication.

Impact of National Accreditation Program for Rectal Cancer guidelines on surgical margin status.

BACKGROUND: The American College of Surgeons established the National Accreditation Program for Rectal Cancer (NAPRC) to standardize rectal cancer care. We sought to assess the impact of NAPRC guidelines at a tertiary care center on surgical margin status. MATERIALS AND METHODS: The Institutional NSQIP database was queried for patients with rectal adenocarcinoma undergoing surgery for curative intent two years prior to and following implementation of NAPRC guidelines. Primary outcome was surgical margin status before (pre-NAPRC) versus after (post-NAPRC) implementation of NAPRC guidelines. RESULTS: Surgical pathology in five (5%) pre-NAPRC and seven (8%) post-NAPRC patients had positive radial margins (p = 0.59); distal margins were positive in three (3%) post-NAPRC and six (7%) post-NAPRC patients (p = 0.37). Local recurrence was observed in seven (6%) pre-NAPRC patients, there were no recurrences to date in post-NAPRC patients (p = 0.15). Metastasis was observed in 18 (17%) pre-NAPRC patients and four (4%) post-NAPRC patients (p = 0.55). CONCLUSION: NAPRC implementation was not associated with a change in surgical margin status for rectal cancer at our institution. However, the NAPRC guidelines formalize evidence-based rectal cancer care and we anticipate that improvements will be greatest in low-volume hospitals which may not utilize multidisciplinary collaboration.

Trends in the Management of Non-emergent Surgery for Diverticular Disease and the Impact of Practice Parameters.

BACKGROUND: Due to the rise in diverticular disease, the ASCRS developed practice parameters to ensure high-quality patient care. Our study aims to evaluate the impact of the 2014 practice parameters on the treatment of non-emergent left-sided diverticular disease. METHODS: This is a retrospective cohort study using the ACS-National Surgical Quality Improvement Project (ACS-NSQIP). Elective sigmoid resections performed by year were evaluated and compared before and after practice parameters were published. RESULTS: Overall, 46,950 patients met inclusion criteria. There was a significant decrease in the number of non-emergent operations when evaluating before and after guideline implementation (P < .001). There was a significant decrease in the number of patients younger than 50 years of age operated electively for diverticular disease (25.8% vs. 23.9%, P = .005). Adoption of minimally invasive surgery continued to increase significantly throughout the study period. CONCLUSIONS: Publication of the 2014 ASCRS practice parameters is associated with a change in management of diverticular disease in the non-emergent setting.

Perioperative use of NSAIDs and the risk of short-term endoscopic recurrence in Crohn's disease patients: A retrospective cohort study.

BACKGROUND: More evidence is needed on the use of NSAID based postoperative pain regimens for Crohn's disease (CD) and its association with recurrence. Our goal is to assess the impact of perioperative use of NSAIDs on endoscopic disease recurrence in patients with CD. METHODS: A retrospective cohort study was conducted. The primary outcome measured was endoscopic disease recurrence within 24 months of surgery, defined as a Rutgeerts score ≥ i2. RESULTS: We identified 107 patients with CD that underwent index ileocolectomy with primary anastomosis between January 2009 and July 2019. Endoscopic disease recurrence was identified in 28 (26.2%) and clinical recurrence in 18 (16.8%) patients. Exposure to NSAIDs did not increase 24-month endoscopic recurrence risk (22.2% vs. 38.5% patients, p = 0.12). CONCLUSION: In patients with CD undergoing elective ileocolic resection and primary ileocolic anastomosis, NSAID use in the perioperative period did not impact endoscopic or clinical disease recurrence rate.

Are IBD Patients Underscored when Determining Postoperative VTE Risk?

BACKGROUND: Patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolism (VTE) following colorectal surgery and there is currently no consensus on post-surgical VTE prevention or specific VTE risk assessment tools. We sought to evaluate VTE risk after colorectal surgery and determine if known risk factors used in risk assessment tools adequate correlate with VTE risk in IBD patients. METHODS: Retrospective cohort study using the National Surgical Quality Improvement Project (NSQIP) Participant User File from 2010 to 2018. RESULTS: A total of 27,679 patients were included; 19,015 (68.7%) had Crohn's disease (CD) and 8664 (31.3%) ulcerative colitis (UC). Of these, 16,749 (60.5%) underwent abdominopelvic procedures, 10,178 (36.8%) complex pelvic procedures, and 752 (2.7%) small bowel operations. The overall VTE rate was 2.3%. The VTE rate in patients with CD and UC was 1.8% and 3.6% (p < 0.001) respectively. Overall median time to VTE was 9 days after surgery. VTE rate was highest in patients who underwent complex pelvic procedures (3.6%; 361/10,178). A risk score was calculated using 16/40 available variables from the Caprini VTE Risk Assessment tool; risk score ranged from 3 to 12 points. Most patients that developed a VTE had a score between 3 and 5 points (75.6%), and only 24.5% had a score of 6 or higher. Patients with higher risk scores did not have a higher VTE incidence. CONCLUSION: Post-surgical VTE rates are high in IBD patients. Over half of the events occurred following discharge and in patients with an apparent low-risk score. Additional studies are warranted to define a recommended postoperative VTE prophylaxis regimen for patients with IBD.

Immunohistochemical analysis of Tn antigen expression in colorectal adenocarcinoma and precursor lesions.

BACKGROUND: The Tn antigen (CD175) is an O-glycan expressed in various types of human adenocarcinomas, including colorectal cancer (CRC), though prior studies have relied heavily upon poorly characterized in-house generated antibodies and lectins. In this study, we explored Tn expression in CRC using ReBaGs6, a well-characterized recombinant murine antibody with high specificity for clustered Tn antigen. METHODS: Using well-defined monoclonal antibodies, expression patterns of Tn and sialylated Tn (STn) antigens were characterized by immunostaining in CRC, in matched peritumoral [transitional margin (TM)] mucosa, and in normal colonic mucosa distant from the tumor, as well as in adenomas. Vicia villosa agglutinin lectin was used to detect terminal GalNAc expression. Histo-scoring (H scoring) of staining was carried out, and pairwise comparisons of staining levels between tissue types were performed using paired samples Wilcoxon rank sum tests, with statistical significance set at 0.05. RESULTS: While minimal intracellular Tn staining was seen in normal mucosa, significantly higher expression was observed in both TM mucosa (p < 0.001) and adenocarcinoma (p < 0.001). This pattern was reflected to a lesser degree by STn expression in these tissue types. Interestingly, TM mucosa demonstrates a Tn expression level even higher than that of the adenocarcinoma itself (p = 0.019). Colorectal adenomas demonstrated greater Tn and STn expression relative to normal mucosa (p < 0.001 and p = 0.012, respectively). CONCLUSIONS: In summary, CRC is characterized by alterations in Tn/STn antigen expression in neoplastic epithelium as well as peritumoral benign mucosa. Tn/STn antigens are seldom expressed in normal mucosa. This suggests that TM mucosa, in addition to CRC itself, represents a source of glycoproteins rich in Tn that may offer future biomarker targets.

Oncotype DX testing does not affect clinical practice in stage IIa colon cancer.

Although studies have demonstrated the 12-gene Oncotype DX Colon Recurrence Score's (RS) validity in predicting recurrence and influence on physician-patient decision-making, its discriminatory power and inability to predict response to treatment make its clinical impact uncertain. We sought to evaluate the influence of RS in the decision to offer adjuvant chemotherapy after resection of stage IIa colon cancer. A review of patients with stage IIa colon cancer who obtained the RS at a tertiary academic medical center was conducted. The main study outcome was decision to start adjuvant chemotherapy. The association between RS and the decision to obtain adjuvant chemotherapy was evaluated utilizing the Wilcoxon rank-sum test and area under the receiver operating characteristic curve. 52 of 105 patients with stage IIa colon cancer underwent RS testing. Overall, seven of 52 patients (13%) received adjuvant chemotherapy. 34 (65%) patients obtained the RS test despite having multiple other recurrence risk factors. There were no significant associations between any patient/tumor characteristic and RS score (all p > 0.08) or starting adjuvant chemotherapy (all p > 0.15). On multivariable analysis, there was no significant effect of RS on the odds of undergoing chemotherapy (OR 1.07, 95% CI 0.98-1.19; p = 0.14). There was no clear association between RS and starting adjuvant chemotherapy (AUC 0.64, 95% CI 0.36-0.91; p = 0.25). RS was not associated with the decision to start adjuvant chemotherapy. Given its lack of association with clinical decision-making and inability to predict clinical outcome, our data suggest the RS should not be obtained in patients with stage IIa colon cancer.

Disparities in industry funding among Colorectal Surgeons: a cross-sectional study.

BACKGROUND: Health Industry and physician collaboration generates innovation. Colorectal Surgeon (CRS) selection to collaborate might not be random. We aim to identify CRS personal and professional characteristics that facilitate collaboration with the Industry. METHOD: Cross-sectional study of Industry payments to CRS (2014-2018) using Open Payments Database from Centers for Medicare & Medicaid Services. Multivariable regression compared variables predicting payment amount including gender, years in practice, leadership positions, H-index, Twitter presence and geographic location. RESULTS: Surgeons who were male received 3.1 times the amount in Industry payments as compared to females (p = 0.014). Chairs and Division Chiefs received 2.7 times the amount in payments as compared to those without these leadership positions (p = 0.003). Surgeons with an H-index ≥ 8 received 2.2 times the amount in payments as compared to those with H-index < 8 (p = 0.001). Surgeons in practice for 12-19 and 20-30 years received 3 times and 4.4 times the amount in payments as compared to surgeons in practice for 1-11 years (p = 0.036 and p = 0.017, respectively). Surgeons in the South received 3.2 times and 2 times the amount in payments as compared to surgeons in the Northeast (p < 0.0005) and in the Midwest (p = 0.006). Surgeons with Twitter accounts received 1.7 times the amount in payments as compared to surgeons without Twitter (p = 0.036). Among Twitter users, those with 321-17,200 followers received 4.7 times and 9.5 times the amount in payments as compared to those with 0-15 and 16-79 followers, respectively (p = 0.008 and p = 0.009). CONCLUSION: Industry payments are more commonly addressed to male, senior surgeons in leadership tracks with strong social media outreach. With the increasing gender and racial variety in the CRS field, it is expected that collaborations between industry and surgeons will become more diverse and inclusive.

Patient's compliance is a contributor to failure of extended antithrombotic prophylaxis in colorectal surgery: prospective cohort study.

BACKGROUND: Venous thromboembolic events (VTE) continue to be a major source of morbidity following colorectal surgery. Selective extended VTE prophylaxis for high-risk patients is recommended; however, provider compliance is low. The purpose of this study is to evaluate whether the "global" extended use of enoxaparin in all colorectal patients is feasible and safe. METHODS: This is a prospective study conducted at a tertiary care center. All Patients undergoing elective colorectal procedures from November 1, 2017 to October 31, 2018 were discharged on 30 days of enoxaparin. Safety of use and patient compliance were examined. RESULTS: Total of 270 patients received extended prophylaxis during the study period (100% of intended patients) with five VTE recorded (1.85%). There was no significant difference in rates of VTE or complications when compared to years of selective prophylaxis (1.26% for 2016, 2.32% for 2017). Only 64% of patients reported full compliance. CONCLUSION: Global use of extended enoxaparin prophylaxis is safe, but does not decrease rates of VTE when compared to selective use. Patient's non-adherence is likely a significant contributing factor.

Preventable Emergency Department Visits After Colorectal Surgery.

BACKGROUND: The emergency department plays a common and critical role in the treatment of postoperative patients. However, many quality improvement databases fail to record these interactions. As such, our understanding of the prevalence and etiology of postoperative emergency department visits in contemporary colorectal surgery is limited. Visits with potentially preventable etiologies represent a significant target for quality improvement, particularly in the current era of rapidly evolving postoperative and ambulatory care patterns. OBJECTIVE: We aimed to characterize postoperative emergency department visits and identify factors associated with these visits for potential intervention. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at an academic medical center. PATIENTS: Consecutive patients undergoing colectomy or proctectomy within the division of colorectal surgery at an academic medical center between 2014 and 2018 were included. MAIN OUTCOME MEASURES: Frequency and indication for emergency department visits, as well as clinical and sociodemographic factors associated with emergency department visits in the postoperative period, were included measures. RESULTS: From the 1763 individual operations, there were 207 emergency department visits from 199 patients (11%) within 30 days of discharge. Two thirds of emergency department visits led to readmission. Median (interquartile range) time to presentation was 8 days (4-16 d). Median time in the emergency department was 7.8 hours (6.0-10.1 h). One third of visits were identified as potentially preventable, most commonly for pain (17%) and stoma complications (excluding dehydration; 13%). A primary language other than English was associated with any postoperative emergency department visit risk ratio of 2.7 (95% CI, 1.3-5.3), as well as a preventable visit risk ratio of 3.6 (95% CI, 1.7-8.0). LIMITATIONS: This was a single-center study and a retrospective review. CONCLUSIONS: One third of emergency department visits after colorectal surgery are potentially preventable. Special attention should be directed toward those patients who do not speak English as a primary language. See Video Abstract at http://links.lww.com/DCR/B648. SE PUEDEN EVITAR LAS VISITAS AL SERVICIO DE URGENCIA DESPUS DE UNA CIRUGA COLORECTAL: ANTECEDENTES:Las unidades de emergencia tienen un rol fundamental en el periodo posterior a una cirugía. Sin embargo muchos de los registros en las bases de datos de estas secciones no son de buena calidad. Por esto analizar la prevalencia y etiología de las visitas postoperatorias en cirugía colorectal resulta ser bastante limitada. Para lograr una mejoría en la calidad es fundamental analizar las causas potencialmente evitables, especialmente al considerer la rapida evolucion de los parametros de medición actuales.OBJETIVO:Nuestro objetivo es caracterizar las visitas postoperatorias al servicio de urgencias e identificar los factores asociados potencialmente evitables.DISEÑO:Estudio de cohorte retrospectivo.AJUSTE:Centro médico académico, 2014-2018.PACIENTES:Pacientes consecutivos sometidos a colectomía o proctectomía dentro de la división de cirugía colorrectal en un centro médico académico entre 2014 y 2018.PRINCIPALES MEDIDAS DE RESULTADO:Frecuencia e indicación de las visitas al servicio de urgencias en el period postoperatorio: factores clínicos y sociodemográficos.RESULTADOS:De 1763 operaciones individuales, hubo 207 visitas al departamento de emergencias de 199 pacientes (11%) en los 30 días posteriores al alta. Dos tercios de las visitas al servicio de urgencias dieron lugar a readmisiones. La mediana [rango intercuartílico] de tiempo hasta la presentación fue de 8 [4-16] días. La mediana de tiempo en el servicio de urgencias fue de 7,8 [6-10,1] horas. Un tercio de las visitas se identificaron como potencialmente evitables, más comúnmente dolor (17%) y complicaciones del estoma (excluida la deshidratación) (13%). En los pacientes con poco manejo del inglés se asoció con una mayor frecuencia razón de visitas al departamento de emergencias posoperatorias [IC del 95%] 2,7 [1,3-5,3], así como opetancialmente evitables con un RR de 3,6 [1,7-8,0].LIMITACIONES:Estudio de un solo centro y revisión retrospectiva.CONCLUSIÓN:Al menos un tercio de las visitas al servicio de urgencias después de una cirugía colorrectal son potencialmente evitables. Se debe prestar especial atención a los pacientes que no hablan inglés como idioma materno. Consulte Video Resumen en http://links.lww.com/DCR/B648.

Omission of or Poor Response to Preoperative Chemoradiotherapy Impacts Radial Margin Positivity Rates in Locally Advanced Rectal Cancer.

BACKGROUND: In the setting of multidisciplinary standardized care of locally advanced rectal cancer, preoperative chemoradiotherapy and total mesorectal excision have become the mainstay treatment. OBJECTIVE: This study aimed to evaluate whether the lack of preoperative chemoradiotherapy or poor response to it is associated with higher radial margin disease involvement in patients with locally advanced rectal cancer. DESIGN: This is a retrospective cohort study using a publicly available database. SETTING: Data were collected from the proctectomy-targeted National Surgical Quality Improvement Project file from 2016 to 2017. PATIENTS: A total of 1161 patients were analyzed. They were categorized into 3 groups: patients who did not receive any preoperative chemoradiotherapy (28.6%), patients who received and responded to preoperative chemoradiotherapy (41.2%), and patients who received but did not respond to preoperative chemoradiotherapy (30.2%). MAIN OUTCOME MEASURES: Response to treatment was determined by using the American Joint Committee on Cancer pretreatment and final pathological staging. Circumferential radial margin was extracted from the targeted proctectomy file. RESULTS: Disease-involved positive circumferential radial margin was found in 86 (7.4%) cases. Positive radial margin was noted in 11 of 479 patients (2.3%) who underwent preoperative chemoradiotherapy and responded to treatment, 30 of 350 patients (8.6%) who did not respond or had a poor response to preoperative chemoradiotherapy, and 45 of 332 patients (13.6%) who did not receive preoperative chemoradiotherapy (p < 0.001). Regression analysis demonstrated that patients who do not receive preoperative chemoradiotherapy or have poor response to it have 6.6 and 4 times higher chances of having a positive radial margin. LIMITATIONS: There is a risk of selection bias, unidentified confounders, and missing data despite the use of a nationwide cohort. CONCLUSIONS: Omission of indicated preoperative chemoradiotherapy or poor response to it is associated with increased risk of radial margin positivity. More efforts are needed for standardized rectal cancer care with the appropriate use of preoperative chemoradiotherapy. See Video Abstract at http://links.lww.com/DCR/B467.

El análisis de regresión demostró que los pacientes que no reciben quimioradioterapia preoperatoria o que tienen escasa respuesta, presentan respectivamente, 6,6 y 4 veces más probabilidades de tener un margen radial +.LIMITACIONES:Existe el riesgo de sesgo de selección, factores de confusión no identificados y datos faltantes a pesar del uso de una cohorte nacional.CONCLUSIONES:La omisión de la quimioradioterapia preoperatoria indicada o la escasa respuesta, se asocian a un mayor riesgo de positividad del margen radial. Se necesitan mayores esfuerzos en la atención estandarizada del cáncer rectal, con el uso adecuado de quimioradioterapia preoperatoria. Consulte Video Resumen en http://links.lww.com/DCR/B467.

Delivery of ERAS Care in an Academic Hospital: An Analysis of Pathway Deviations and Obstacles to Adherence.

Enhanced Recovery after Surgery (ERAS) pathways in colorectal surgery improve outcomes and reduce disparities, but pathway adherence rates are variable. Sustainability of adherence following initial implementation, particularly in academic settings with trainee involvement, is underexplored. This study measures and describes ERAS adherence for 163 consecutive patients undergoing elective colorectal resection in an academic colorectal surgery department with a well-established ERAS pathway. Providers, including residents and nursing staff, were surveyed regarding pathway knowledge and obstacles to adherence. Adherence was higher preoperatively (80%) and intraoperatively (93%) than postoperatively (61%). Opioid-sparing analgesia and bowel motility agents were underdosed on up to 63% of hospital days, without clinical rationale in ≥50% of cases. Providers cited peer teaching (71%) as the primary source of pathway knowledge and identified individual surgeon preferences as an obstacle to adherence. Formalized ERAS pathway education, communication, and coordination among attending physicians are needed to reduce provider-driven deviation in an academic setting.

Patients Undergoing Ileoanal Pouch Surgery Experience a Constellation of Symptoms and Consequences Representing a Unique Syndrome: A Report from the Patient-Reported Outcomes After Pouch Surgery (PROPS) Delphi Consensus Study.

BACKGROUND: Functional outcomes after ileoanal pouch creation have been studied; however, there is great variability in how relevant outcomes are defined and reported. More importantly, the perspective of patients has not been represented in deciding which outcomes should be the focus of research. OBJECTIVE: The primary aim was to create a patient-centered definition of core symptoms that should be included in future studies of pouch function. DESIGN: This was a Delphi consensus study. SETTING: Three rounds of surveys were used to select high-priority items. Survey voting was followed by a series of online patient consultation meetings used to clarify voting trends. A final online consensus meeting with representation from all 3 expert panels was held to finalize a consensus statement. PATIENTS: Expert stakeholders were chosen to correlate with the clinical scenario of the multidisciplinary team that cares for pouch patients, including patients, colorectal surgeons, and gastroenterologists or other clinicians. MAIN OUTCOME MEASURES: A consensus statement was the main outcome. RESULTS: patients, 62 colorectal surgeons, and 48 gastroenterologists or nurse specialists completed all 3 Delphi rounds. Fifty-three patients participated in online focus groups. One hundred sixty-one stakeholders participated in the final consensus meeting. On conclusion of the consensus meeting, 7 bowel symptoms and 7 consequences of undergoing ileoanal pouch surgery were included in the final consensus statement. LIMITATIONS: The study was limited by online recruitment bias. CONCLUSIONS: This study is the first to identify key functional outcomes after pouch surgery with direct input from a large panel of ileoanal pouch patients.

Patients Undergoing Ileoanal Pouch Surgery Experience a Constellation of Symptoms and Consequences Representing a Unique Syndrome: A Report From the Patient-Reported Outcomes After Pouch Surgery (PROPS) Delphi Consensus Study.

OBJECTIVE: The primary aim was to create a patient-centered definition of core symptoms that should be included in future studies of pouch function. BACKGROUND: Functional outcomes after ileoanal pouch creation have been studied; however, there is great variability in how relevant outcomes are defined and reported. More importantly, the perspective of patients has not been represented in deciding which outcomes should be the focus of research. METHODS: Expert stakeholders were chosen to correlate with the clinical scenario of the multidisciplinary team that cares for pouch patients: patients, colorectal surgeons, gastroenterologists/other clinicians. Three rounds of surveys were employed to select high-priority items. Survey voting was followed by a series of online patient consultation meetings used to clarify voting trends. A final online consensus meeting with representation from all 3 expert panels was held to finalize a consensus statement. RESULTS: One hundred ninety-five patients, 62 colorectal surgeons, and 48 gastroenterologists/nurse specialists completed all 3 Delphi rounds. Fifty-three patients participated in online focus groups. One hundred sixty-one stakeholders participated in the final consensus meeting. On conclusion of the consensus meeting, 7 bowel symptoms and 7 consequences of undergoing ileoanal pouch surgery were included in the final consensus statement. CONCLUSIONS: This study is the first to identify key functional outcomes after pouch surgery with direct input from a large panel of ileoanal pouch patients. The inclusion of patients in all stages of the consensus process allowed for a true patient-centered approach in defining the core domains that should be focused on in future studies of pouch function.

Recurrence and Survival of Neuroendocrine Neoplasms of the Rectum: Single-Center Experience.

BACKGROUND: In 2010, the World Health Organization proposed that rectal neuroendocrine neoplasms (NENs) be considered malignant. We hypothesized that patients with small, low-grade, locally excised tumors have a low risk of recurrence and death. METHODS: Retrospective review of institutional database 2006-2017 including consecutive adults with newly diagnosed rectum NENs. Outcome measures included risk of recurrence and 5-year overall survival. RESULTS: A total of 122 patients were diagnosed with rectal NENs. Most patients were asymptomatic and diagnosed during screening colonoscopy (80, 66.1%), had small tumors (median 0.6 cm, IQR 0.5-1) with intact muscularis propria on EUS (62/65, 95.4%), and were low grade (2017 WHO grades 1-2, n = 116, 95.1%). Lymph node and distant metastasis were found in 4 (3.3%) and 4 (3.3%) of patients, respectively. Patients were treated with local excision in 93.4% of cases with polypectomy (52, 42.6%), endoscopic mucosal resection (48, 39.3%), and transanal excision (14, 11.5%). Three patients (2.5%) required abdominoperineal resection or low anterior resection, and five patients (4.1%) received adjuvant chemotherapy. Of 87 patients surveilled, 4 (4.6%) recurred at a median time of 1 year (IQR 0.6-8). Death from neuroendocrine neoplasms occurred in 5 (4.1%) patients, all with lymph node (1/4) or metastatic disease (4/5) on presentation. Median time to death from NEN was 0.8 years (0.7-2.4). Overall 5-year survival for patients with localized disease was 98.2% (95% CI 93-99.5, Fig. 1). CONCLUSION: Patients with small, low grade rectal NENs treated with local excision have excellent oncologic outcomes.
