Mentorship of Junior Surgical Faculty Across Academic Programs in Surgery.

Importance: Because mentorship is critical for professional development and career advancement, it is essential to examine the status of mentorship and identify challenges that junior surgical faculty (assistant and associate professors) face obtaining effective mentorship. Objective: To evaluate the mentorship experience for junior surgical faculty and highlight areas for improvement. Design, Setting, and Participants: This qualitative study was an explanatory sequential mixed-methods study including an anonymous survey on mentorship followed by semistructured interviews to expand on survey findings. Junior surgical faculty from 18 US academic surgery programs were included in the anonymous survey and interviews. Survey responses between "formal" (assigned by the department) vs "informal" (sought out by the faculty) mentors and male vs female junior faculty were compared using χ2 tests. Interview responses were analyzed for themes until thematic saturation was achieved. Survey responses were collected from November 2022 to August 2023, and interviews conducted from July to December 2023. Exposure: Mentorship from formal and/or informal mentors. Main Outcomes and Measures: Survey gauged the availability and satisfaction with formal and informal mentorship; interviews assessed broad themes regarding mentorship. Results: Of 825 survey recipients, 333 (40.4%) responded; 155 (51.7%) were male and 134 (44.6%) female. Nearly all respondents (319 [95.8%]) agreed or strongly agreed that mentorship is important to their surgical career, especially for professional networking (309 respondents [92.8%]), career advancement (301 [90.4%]), and research (294 [88.3%]). However, only 58 respondents (18.3%) had a formal mentor. More female than male faculty had informal mentors (123 [91.8%] vs 123 [79.4%]; P = .003). Overall satisfaction was higher with informal mentorship than formal mentorship (221 [85.0%] vs 40 [69.0%]; P = .01). Most male and female faculty reported no preferences in gender or race and ethnicity for their mentors. When asked if they had good mentor options if they wanted to change mentors, 141 (47.8%) responded no. From the interviews (n = 20), 6 themes were identified, including absence of mentorship infrastructure, preferred mentor characteristics, and optimizing mentorship. Conclusions and Relevance: Academic junior surgical faculty agree mentorship is vital to their careers. However, this study found that few had formal mentors and almost half need more satisfactory options if they want to change mentors. Academic surgical programs should adopt a framework for facilitating mentorship and optimize mentor-mentee relationships through alignment of mentor-mentee goals and needs.

Use of a 5-Item Modified Frailty Index for Assessing Outcomes After Hartmann's Reversal: An ACS-NSQIP Study.

BACKGROUND: Half of all patients with an end colostomy after sigmoid colectomy (Hartmann's procedure) never undergo Hartmann's reversal, frequently secondary to frailty. This retrospective cohort study evaluates the utility of a five-item modified frailty index (mFI-5) in predicting post-operative outcomes after Hartmann's reversal. METHODS: The National Surgery Quality Improvement Program (NSQIP) database captured patients with elective Hartmann's reversals from 2011 to 2020. Clinical covariates were evaluated with univariate analysis and modified Poisson regression to determine association with overall morbidity, overall mortality, and extended length of stay (eLOS) when categorized by mFI-5 score. RESULTS: 15,172 patients underwent elective Hartmann's reversal (91.6% open and 8.4% laparoscopic). Patients were grouped by mFI-5 score (0: 48.7%, 1: 38.2%, ≥ 2: 13.1%). Adjusted multivariable analysis showed frail patients (mFI-5≥2) had increased overall mortality (OR 2.23, 95% CI 1.21-4.11), morbidity (OR 1.23, 95% CI 1.12-1.35), and eLOS (OR 1.12, 95% 1.02-1.23). Among frail patients, a laparoscopic approach was associated with decreased overall morbidity (OR .64, 95% CI 0.56-.73) and decreased eLOS (OR .46, 95% CI 0.39-.54) when compared to open approach. DISCUSSION: An mFI-5 of ≥2 was associated with greater morbidity, mortality, and eLOS following Hartmann's reversal. However, there were no mortality or eLOS differences in patients with an mFI-5 of 1 and only a 14% increase in any morbidity, making these patients potentially good candidates for Hartmann's reversal. Furthermore, laparoscopic surgery was associated with a protective effect for overall morbidity and eLOS, potentially mitigating some of the risk associated with higher frailty scores.

Impact of Preoperative Factors in Patients With IBD on Postoperative Length of Stay: A National Surgical Quality Improvement Program-Inflammatory Bowel Disease Collaborative Analysis.

BACKGROUND: Patients with IBD are challenging to manage perioperatively because of disease complexity and multiple comorbidities. OBJECTIVE: To identify whether preoperative factors and operation type were associated with extended postoperative length of stay after IBD-related surgery, defined by 75th percentile or greater (n = 926; 30.8%). DESIGN: This was a cross-sectional study based on a retrospective multicenter database. SETTING: The National Surgery Quality Improvement Program-Inflammatory Bowel Disease Collaborative captured data from 15 high-volume sites. PATIENTS: A total of 3008 patients with IBD (1710 with Crohn's disease and 1291 with ulcerative colitis) with a median postoperative length of stay of 4 days (interquartile range, 3-7) from March 2017 to February 2020. MAIN OUTCOME MEASURES: The primary outcome was extended postoperative length of stay. RESULTS: On multivariable logistic regression, increased odds of extended postoperative length of stay were associated with multiple demographic and clinical factors (model p < 0.001, area under receiver operating characteristic curve = 0.85). Clinically significant contributors that increased postoperative length of stay were rectal surgery (vs colon; OR, 2.13; 95% CI, 1.52-2.98), new ileostomy (vs no ileostomy; OR, 1.50; 95% CI, 1.15-1.97), preoperative hospitalization (OR, 13.45; 95% CI, 10.15-17.84), non-home discharge (OR, 4.78; 95% CI, 2.27-10.08), hypoalbuminemia (OR, 1.66; 95% CI, 1.27-2.18), and bleeding disorder (OR, 2.42; 95% CI, 1.22-4.82). LIMITATIONS: Retrospective review of only high-volume centers. CONCLUSIONS: Patients with IBD who were preoperatively hospitalized, who had non-home discharge, and who underwent rectal surgery had the highest odds of extended postoperative length of stay. Associated patient characteristics included bleeding disorder, hypoalbuminemia, and ASA classes 3 to 5. Chronic corticosteroid, immunologic, small molecule, and biologic agent use were insignificant on multivariable analysis. See Video Abstract. IMPACTO DE LOS FACTORES PREOPERATORIOS EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL EN LA DURACIN DE LA ESTANCIA POSTOPERATORIA UN ANLISIS COLABORATIVO DEL PROGRAMA NACIONAL DE MEJORA DE LA CALIDAD QUIRRGICAENFERMEDAD INFLAMATORIA INTESTINAL: ANTECEDENTES:Los pacientes con enfermedad inflamatoria intestinal son difíciles de manejar perioperatoriamente debido a la complejidad de la enfermedad y a múltiples comorbilidades.OBJETIVO:Este estudio tuvo como objetivo identificar si los factores preoperatorios y el tipo de operación se asociaron con una estadía postoperatoria prolongada después de una cirugía relacionada con enfermedad inflamatoria intestinal, definida por el percentil 75 o mayor (n = 926, 30.8%).DISEÑO:Este fue un estudio transversal basado en una base de datos multicéntrica retrospectiva.ESCENARIO:Datos capturados de quince sitios de alto volumen en El Programa Nacional de Mejoramiento de la Calidad de la Cirugía-Enfermedad Intestinal Inflamatoria en colaboración.PACIENTES:Un total de 3,008 pacientes con enfermedad inflamatoria intestinal (1,710 con enfermedad de Crohn y 1,291 con colitis ulcerosa) con una mediana de estancia postoperatoria de 4 días (RIC 3-7) desde marzo de 2017 hasta febrero de 2020.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la extensión de la estancia postoperatoria.RESULTADOS:En la regresión logística multivariable, el aumento de las probabilidades de prolongar la estancia postoperatoria se asoció con múltiples factores demográficos y clínicos (modelo p<0.001, área bajo la curva ROC - 0.85). Los contribuyentes clínicamente significativos que aumentaron la duración de la estancia postoperatoria fueron la cirugía rectal (frente al colon) (OR 2.13, IC del 95 %: 1.52 a 2.98), una nueva ileostomía (frente a ninguna ileostomía) (OR 1.50, IC del 95 %: 1.15 a 1.97), hospitalización preoperatoria (OR 13.45, IC 95% 10.15-17.84), alta no domiciliaria (OR 4.78, IC 95% 2.27-10.08), hipoalbuminemia (OR 1.66, IC 95% 1.27-2.18) y trastorno hemorrágico (OR 2.42, IC 95% 1.22-4.82).LIMITACIONES:Revisión retrospectiva de solo centros de alto volumen.CONCLUSIONES:Los pacientes con enfermedad inflamatoria intestinal que fueron hospitalizados antes de la operación, que tuvieron alta no domiciliaria y que se sometieron a cirugía rectal tuvieron las mayores probabilidades de prolongar la estancia postoperatoria. Las características asociadas de los pacientes incluyeron trastorno hemorrágico, hipoalbuminemia y clases ASA 3-5. El uso crónico de corticosteroides, inmunológicos, agentes de moléculas pequeñas y de agentes biológicos no fue significativo en el análisis multivariable. (Traducción-Dr. Jorge Silva Velazco ).

Detection of Ischemic Colitis on Routine Lower Endoscopy and Its Implications After Repair of Ruptured Abdominal Aortic Aneurysm.

BACKGROUND: Ischemic colitis (IC) is a known significant complication after repair of a ruptured abdominal aortic aneurysm (rAAA). Lower endoscopy (colonoscopy or flexible sigmoidoscopy) is a helpful adjunct to aid decision making for surgical exploration. We believe routine use of lower endoscopy after rAAA repair provides better patient care through expeditious diagnosis and surgical care. METHODS: We performed a retrospective chart review of rAAA repairs from 2008 to 2019. All patients undergo screening lower endoscopy after rAAA repair at our institution. The incidence of IC, mortality, and diagnostic characteristics of routine lower endoscopy was analyzed. RESULTS: Of these, 182 patients underwent rAAA repair, among which 139 (76%) underwent routine lower endoscopy. Ischemic colitis of any grade was diagnosed in 25% of patients. The 30-day mortality was 11% compared to 19% in those without lower endoscopy. The presence of IC portended a 4-fold increase in mortality rate compared to those without (26% vs 6%, P = .005). Surgical exploration rate was 8% after routine lower endoscopy. Grade III ischemia on lower endoscopy had a sensitivity of 50% (95% CI 12-88) and specificity of 99% (95% CI 94-100) for transmural necrosis. DISCUSSION: We found increased incidence of IC and reliable diagnostic characteristics of routine lower endoscopy in predicting the presence of transmural colonic ischemia. There was decreased mortality with use of routine lower endoscopy but this was not statistically significant.

The Effect of an Enhanced Recovery Program on Elective Right Hemicolectomies for Crohn's Disease vs. Colon Cancer: A Retrospective Cohort Analysis.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are widely employed in colorectal surgery, successful in reducing postoperative morbidities and hospital length of stay (LOS). However, ERAS effects on the inflammatory bowel disease population remain unclear. This study examines the postoperative course of both Crohn's disease (CD) and colon cancer (CC) patients after elective right hemicolectomies and compares the effectiveness of ERAS protocol. METHODS: A retrospective analysis was performed on patients with CD and CC undergoing elective right hemicolectomies and ileocecectomies from January 2014 through June 2016 (pre-ERAS) and January 2017 through April 2019 (post-ERAS) from a single tertiary care center. Patient demographics and perioperative variables were examined, including prolonged postoperative ileus (PPOI), hospital LOS, and 30-day readmission. RESULTS: 98 CC patients and 91 CD patients met the inclusion criteria. The pre-ERAS CC and post-ERAS CC cohorts were significantly different: post-ERAS had fewer patients with congestive heart failure and chronic obstructive pulmonary disease and had higher albumin levels. The pre-ERAS CC cohort had significantly longer operative durations and higher rates of concomitant procedures than the post-ERAS CC cohort. Both patients with CC and CD had a reduction in LOS with implementation of ERAS, decreasing by 2.24 days (P = .002) and 1.21 days (P = .038), respectively. There was a reduction in rates of organ space infections with CD (pre .132, post .00, P = .007). There was a trend towards an increased rate of PPOI with CD (Pre .079, Post .226, P = .062). DISCUSSION: The ERAS protocol significantly reduced LOS for both groups, without increasing 30-day readmission rates or other morbidities.

Management of Nonoperative Diverticulitis : Is Surgical Admission Always Best?

BACKGROUND: Institutional pathways (IPs) allow efficient utilization of health care resources. Recent literature reports decreased hospital length of stay (LOS), complications, and costs with the admittance of surgical disease to surgical services. Our study aimed to demonstrate that admission to surgery for nonoperative, acute diverticulitis reduces hospital LOS, and cost, with comparable complication rates. METHODS: In January 2017, we defined IPs for diverticulitis, mandating emergency department admission to a surgical service. Patients admitted from October 2015 to June 2016 (pre-protocol, control cohort) were compared with those admitted January 2017-September 2018 (post-protocol, IP cohort). Primary outcomes included hospital LOS, direct cost, indirect cost, total cost, and 30-day readmission. Student's 2-tailed t-test and chi-square analysis were utilized, with statistical significance P < .05. RESULTS: Nonoperative management of acute diverticulitis occurred in 62 (74%) patients in the control cohort. One hundred and eleven patients (85%) were admitted to the IP cohort. Patient characteristics were similar, except for a higher percentage of surgical patients utilizing private insurance and younger in age. Interestingly, no difference in hospital LOS (3.8 vs 4.7 days; P = 0.07), direct cost ($2639.44 vs $3251.52; P = .19), or overall cost ($5968.67 vs $6404.08, P = .61) was found between cohorts. Thirty-day readmission rates were comparable at 8% and 11% (P = .59). CONCLUSION: Institutional policy mandating admissions for patients receiving nonoperative management of diverticulitis to surgical services does not reduce hospital LOS or cost. This argues that admission to medical services may be an acceptable practice. This raises the question, is acute diverticulitis always a surgical issue?

The Impact of an Enhanced Recovery Program on Loop Ileostomy Closure.

BACKGROUND: The implementation of enhanced recovery after surgery (ERAS) protocols has decreased the length of stay (LOS) and complications in colorectal procedures. However, little data has been published on the subset of patients undergoing loop ileostomy closure. We investigated the outcomes of loop ileostomy reversals prior to and after initiation of an ERAS protocol. METHODS: Patients undergoing ileostomy reversal over a 5-year period by 4 colorectal surgeons were studied and divided into pre-ERAS patients and ERAS patients in a retrospective, case-control study. Patient demographics, comorbidities, LOS, underlying disease process, index intra-abdominal procedure, readmission rate, and complications were evaluated. RESULTS: Overall, 208 patients were analyzed 149 pre-ERAS and 59 ERAS-with median LOS significantly lower in the ERAS group than the pre-ERAS group (50.8 hours vs. 96.1 hours, P < .0001). In subgroup analysis, the LOS was significantly lower if the index procedure performed was laparoscopic when comparing ERAS to pre-ERAS (49.9 hours vs. 96.6 hours, P < .001). ERAS did not confer a significant decrease in the LOS during ileostomy reversal with open index procedures (72.9 hours vs. 95.5 hours, P = .05). CONCLUSION: Utilizing an ERAS protocol is safe and effective for loop ileostomy closure with a shorter LOS and no difference in complication rates or 30-day readmission rates.

After Elective Sigmoid Colectomy for Diverticulitis, Does Recurrence-Free Mean Symptom-Free?

After elective sigmoidectomy for diverticulitis, patients may experience persistent abdominal symptoms. This study aimed to determine the incidence and characteristics of persistent symptoms (PSs) and their risk factors in patients who had no reported recurrence after elective sigmoidectomy. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included. After retrospective review of medical records, patients were contacted with a questionnaire to inquire about recurrence of diverticulitis and persistent abdominal symptoms since resection. Outcomes examined were prevalence of and risk factors for PSs after elective sigmoidectomy. Of 662 included patients, 346 completed the questionnaire and had no recurrent diverticulitis. PSs were reported by 43.9 per cent of the patients. The mean follow-up was 87 months. Female gender and preoperative diagnosis of irritable bowel syndrome were independent risk factors for PSs (Relative Risk 1.65, P < 0.001 and Relative Risk 1.41, P = 0.014). Previous IV antibiotics treatment was associated with PSs (P = 0.034) but not with a significant risk factor. As the follow-up interval increased, prevalence of PSs decreased (P = 0.006). More than 40 per cent of patients experienced persistent abdominal symptoms after sigmoidectomy for diverticulitis. Female patients and those with irritable bowel syndrome were at significantly increased risk.

A NSQIP analysis of trends in surgical outcomes for rectal cancer: What can we improve upon?

BACKGROUND: There is significant variation in rectal cancer outcomes in the USA, and reported outcomes have been inferior to those in other countries. In recognition of this fact, the American College of Surgeons (ACS) recently launched the Commission on Cancer (CoC) National Accreditation Program for Rectal Cancer (NAPRC) in an effort to further optimize rectal cancer care. Large surgical databases will play an important role in tracking surgical and oncologic outcomes. Our study sought to explore the trends in surgical outcomes over the decade prior to the NAPRC using a large national database. METHODS: The ACS National Surgical Quality Improvement Program (NSQIP) database from 2005 to 2017 was used to select colorectal cancer cases which were divided into abdominal-colonic (AC) and pelvic-rectal (PR) cohorts based upon the operation performed. Outcomes of interest were occurrence of any major surgical complication, mortality within 30 days of procedure, and postoperative length of stay (LOS). Chi-square and two sample t-tests were used to evaluate association between various risk factors and outcomes. Modified Poisson regression was used to compare and estimate the unadjusted and adjusted effect of procedure type on the outcomes. STATA 15.1 was used for analysis and statistical significance was set at 0.05. RESULTS: A total of 34,159 patients were analyzed. AC cases constituted 50.7% of the overall cohort. The two groups were relatively similar in demographic distribution, but the PR patients had higher rates of hypoalbuminemia and were sicker (ASA class 3 or greater). Rates of non-sphincter preserving operations ranged from 30 to 34%. Higher complication rates in the PR cohort were mainly infectious and surgical site complications, while rates of deep vein thrombosis and pulmonary embolism were similar between the two cohorts. On bivariate analysis, rates of mortality were similar between the two groups (AC: 1.02% vs PR: 0.91%, p = 0.395), while PR patients were found to be 1.36 times (95% CI: 1.32-1.41) more likely to have major complications and 1.40 times (95% CI: 1.35-1.44) more likely to have an extended LOS as compared to the AC patients. After multivariable analysis, PR patients continued to have a higher likelihood of major complications (IRR: 1.31, 95% CI 1.25-1.36) and extended LOS (IRR: 1.38, 95% CI: 1.33-1.43). 10-year trends showed a significant reduction in the percentage of patients with prolonged lengths of hospitalization as well as a reduction of nearly 20% in the mean LOS, but without improvement in morbidity or mortality. CONCLUSIONS: Patients undergoing PR operations were more likely to have had major complications than were patients who underwent AC procedures; unfortunately no improvement in the rate of these complications or in mortality occurred. Perhaps the significant reduction in LOS is due in part to an increased prevalence of minimally invasive surgery and/or enhanced recovery protocols. Data were found to be lacking within NSQIP for several important variables including key oncologic data, stratification by surgical volume, and patient geographic location. We anticipate that the NAPRC should help improve PR surgical and oncologic outcomes including decreasing morbidity and mortality rates during the next decade.

Elective Laparoscopic Sigmoid Colectomy for Diverticulitis-an Updated Look at Recurrence After Surgery.

BACKGROUND: Surgical management of diverticulitis is evolving and the decision to offer elective sigmoidectomy for diverticulitis has become more individualized. However, preoperative variables that may predict recurrent diverticulitis after resection and guide surgical decision-making were not well studied. METHODS: This was a retrospective chart review with a prospective questionnaire follow-up of patients. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included and their medical records reviewed. They were then contacted with a questionnaire to inquire about recurrence of diverticulitis since resection. The primary outcome was rate of recurrent diverticulitis after elective sigmoidectomy. The secondary outcome was risk factors for recurrence after sigmoidectomy. RESULTS: Of 662 patients who underwent elective sigmoidectomy for diverticulitis, 361 had long-term follow-up data available. Mean follow-up was 86 months. Indication for surgery was uncomplicated recurrent diverticulitis in 50%. Recurrent diverticulitis developed in 15 (4.2%) patients. Mean time to recurrence was 55 (range, 6-109) months. All recurrences were confirmed by CT scan. Univariate analysis showed that preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was significantly more prevalent in patients who experienced recurrent diverticulitis after sigmoidectomy (p = 0.049 and p = 0.02); however, these variables did not predict recurrence after resection. CONCLUSIONS: Overall rate of recurrent diverticulitis after elective sigmoidectomy was 4.2%. Preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was associated with but not significant predictor of recurrence after elective resection.

Laparoscopic Surgery for Diverticular Fistulas: Outcomes of 111 Consecutive Cases at a Single Institution.

BACKGROUND: The purpose of this study was to review our experience with laparoscopic colectomy and fistula resection, evaluate the frequency of conversion to open, and to compare the perioperative courses of the complete laparoscopic and conversion groups. METHODS: This study is a retrospective analysis of 111 consecutive adult patients with diverticular fistulae diagnosed clinically or radiographically over 11 years at a single institution. Five patients were excluded for preoperative comorbidities. The remaining 106 consecutive patients underwent minimally invasive sigmoid colectomy with primary anastomosis. Preoperative, intraoperative, and postoperative variables were collected from the colorectal surgery service database. A retrospective cohort analysis was performed between laparoscopic and converted groups. RESULTS: Within the group, 47% had colovesical fistulas, followed by colovaginal, coloenteric, colocutaneous, and colocolonic fistulas. The overall conversion rate to laparotomy was 34.7% (n = 37). The most common reason for conversion was dense fibrosis. Mean operative time was similar between groups. Combined postoperative complications occurred in 26.4% of patients (21.4% laparoscopic and 37.8% converted, p = 0.075). Length of stay was significantly shorter in the laparoscopic group (5.8 vs 8.1 days, p = 0.014). There were two anastomotic leaks, both in the open group. There were no 30-day mortalities. CONCLUSIONS: Laparoscopic sigmoid colectomy for diverticular fistula is safe, with complication rates comparable to open sigmoid resection. We identify a conversion rate which allows the majority of patients to benefit from minimally invasive procedures.

Impact of Interhospital Transfer on Outcomes in Non-emergency Colorectal Surgery.

BACKGROUND: A paucity of data exists on the impact of transfer status on outcomes for patients undergoing non-emergency (urgent) colorectal surgery. This study characterized transferred patients undergoing urgent colorectal surgery and determined which patient comorbidities significantly contributed to poor outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2013 was used. Urgent direct admissions undergoing colon, rectum, or small bowel operations were compared to urgent transfers using bivariate and multivariable analysis models. Primary outcomes were overall complications, hospital length of stay, and mortality. RESULTS: A total of 82,151 admissions were analyzed. After multivariable analysis, direct admission patients had nearly similar risk of complications (RR = 0.95; 95% CI 0.91-0.99) and length of hospital stay (7% shorter; 95% CI 4-9%), as well as no difference in mortality (RR = 0.94; 95% CI 0.80-1.11). CONCLUSIONS: Transfer status alone confers minimal risk toward higher complication rates and longer hospital length of stay in patients undergoing urgent colorectal surgery, and the poor outcomes observed in this cohort are largely due to patient comorbidities and disease severity. Our results suggest that outcomes in transferred colorectal surgery patients undergoing urgent operations depend mainly on operative acuity and clinical factors, and to a lesser degree transfer status.

Complications and surgical outcomes after interhospital transfer vs direct admission in colorectal surgery: A National Surgical Quality Improvement Program analysis.

BACKGROUND: Interhospital transfer is common among patients undergoing colorectal surgery. The purpose of this study was to determine surgical outcomes after transfer vs direct admission in patients undergoing colorectal surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2012 was used. Colorectal operations were selected, including both emergency and nonemergency cases. Transfers were compared with direct admissions using a complex comorbidity analysis model. Primary outcomes of interest were mortality, extended hospital length of stay, and complication rates. RESULTS: The study included 121,040 admissions. After adjusting for multiple patient factors and comorbidities, nonemergency transfers still had higher mortality rates (RR = 1.20; P < .05), longer length of hospital stay (RR = 1.24; P < .05), and higher complication rates (RR = 1.18; P < .05). CONCLUSIONS: Preoperative hospital transfer is common among patients requiring colorectal surgery. Despite extensive propensity score matching, nonemergency transfers have higher rates of mortality, longer length of hospital stay, and higher overall complication rates compared with direct admissions. Transfer status is an important variable in hospital performance models and should be taken into consideration when analyzing hospital outcomes.

Increased Incidence of Surgical Site Infection in IBD Patients.

BACKGROUND: Surgical site infection is a key hospital-level patient safety indicator. All risk factors for surgical site infection are not always taken into account and adjusted for. OBJECTIVE: This study aimed to measure the impact of IBD in comparison with diverticulitis and colorectal cancer on the national rates of surgical site infection. DESIGN: The American College of Surgeons National Surgical Quality Improvement Project database was queried for all patients undergoing elective colectomy for colon cancer, diverticulitis, and IBD from 2008 through 2012. OUTCOME MEASURES: The association between surgical site infection and IBD patients was assessed. Patient demographics, rates of surgical site infection, wound class, return to operating room, and various patient characteristics were analyzed. Logistic regression was performed to determine the association with surgical site infection. RESULTS: The query yielded 71,845 patients undergoing elective colectomy. Of these patients, 42,132 had colon cancer, 22,143 had diverticulitis, and 7570 had IBD. The rate of surgical site infection was 12.0% for colon cancer, 12.8% for diverticulitis, and 18.0% for IBD. Return to operating room within 30 days was 7.3% for IBD patients, 4.4% for patients with diverticulitis, and 4.9% for patients with colorectal cancer. Return to operating room within 30 days had the highest correlation to surgical site infection in both univariate and multivariable analysis. Other associative factors for surgical site infection common to both analyses included diabetes mellitus, smoking, open procedures, and obesity. LIMITATIONS: This study was limited by the data collection errors inherent to large databases, exclusion of emergent operations, and the inability to identify patients taking immunosuppressive agents. CONCLUSIONS: Patients with IBD undergoing elective colectomy have significantly increased rates of surgical site infection, specifically deep and organ/space infections. Given this information, risk adjustment models for surgical site infection may need to include IBD in their calculation.

Laparoscopic sigmoid colectomy for complicated diverticulitis is safe: review of 576 consecutive colectomies.

INTRODUCTION: Laparoscopic resection of diverticular disease is typically offered to selected patients. We present the outcomes of laparoscopic colectomy in consecutive patients suffering from either simple diverticulitis (SD) or complicated diverticulitis (CD). PURPOSE: To examine the outcomes of laparoscopic sigmoid colectomy for complicated diverticulitis. METHODS: Between December 2001 and May 2013, all patients with diverticulitis requiring elective operation were offered laparoscopic sigmoid colectomy as the initial approach. All cases were managed at a large tertiary care center on the colorectal surgery service. Preoperative, intraoperative, and postoperative variables were prospectively entered into the colorectal surgery service database (CRSD) and analyzed retrospectively. RESULTS: Of the 576 patients in the CRSD, 139 (24.1%) had CD. The overall conversion rate was 12.8% (n = 74). The average BMI was 29.8 kg/m(2). The conversion rate for CD was 12.2%. The return of bowel function time was delayed in the CD group when compared to the SD group (3.1 vs 3.8 days, p = 0.04). The hospital length of stay (HLOS) was similar between the groups (5.1 vs 5.8 days, p = 0.08). The overall anastomotic leak rate was 2.1% (n = 12). Patients undergoing laparoscopic resection for SD had a postoperative complication rate of 10.0% (n = 38), whereas those with CD had a postoperative morbidity rate of 19.6% (n = 24). CD patients who had conversion to an open procedure had an even higher rate of postoperative complications (29.4%, n = 5, p = 0.35). On non-parsimonious multivariate adjustment, only CD (RR 1.96, 95% CI 1.11-3.46, p = 0.02) was found to be an independent risk factor for the development of postoperative complications. CONCLUSIONS: Complicated diverticulitis did not affect the conversion rate to an open procedure. However, patients with CD are prone to postoperative complications. The laparoscopic approach to sigmoid colectomy is safe and preferable in experienced hands.

Incidence of Ostomy Site Incisional Hernias after Stoma Closure.

This study sought to evaluate the incidence of ostomy site incisional hernias after stoma reversal at a single institution. This is a retrospective analysis from 2001 to 2011 evaluating the following demographics: age, gender, indication for stoma, urgent versus elective operation, time to closure, total follow-up time, the incidence of and reoperation for stoma incisional hernia, diabetes, postoperative wound infection, smoking status within six months of surgery, body mass index, and any immunosuppressive medications. A total of 365 patients were evaluated. The median follow-up time was 30 months. The clinical hernia rate was 19 percent. Significant risk factors for hernia development were age, diabetes, end colostomies, loop colostomies, body mass index >30, and undergoing an urgent operation. The median time to clinical hernia detection was 32 months. Sixty-four percent of patients required surgical repair of their stoma incisional hernia. A significant number of patients undergoing stoma closure developed an incisional hernia at the prior stoma site with the majority requiring definitive repair. These hernias are a late complication after stoma closure and likely why they are under-reported in the literature.

Risk of catheter-associated deep venous thrombosis in inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease confers a hypercoagulable state. A large number of these patients require central venous access in the form of peripherally inserted central catheters for long-term intravenous therapies. Our clinical observations suggested that these patients had a higher incidence of catheter-associated deep venous thrombosis than that of the general population. OBJECTIVE: The aim of this study was to examine the relationship between IBD and catheter-associated deep venous thrombosis. DESIGN: A retrospective chart review was conducted of all patients who underwent peripherally inserted central catheter line placement between 2009 and 2011. SETTING: This study was performed at a single-institution tertiary referral center. PATIENTS: All patients who underwent peripherally inserted central catheter line placement were identified. OUTCOME MEASURES: The risk of catheter-associated deep venous thrombosis in IBD patients was assessed. This risk was compared with known risk factors such as malnutrition, malignancy, diabetes mellitus, and tobacco use. Multivariate analysis was performed. Catheter size, indication for placement, and vein location of catheter-associated deep venous thrombosis were identified in the IBD population. RESULTS: There were 7179 peripherally inserted central catheter lines placed during the study period; the overall incidence of catheter-associated deep venous thrombosis was 2.1% (148/7179). The incidence of catheter-associated deep venous thrombosis among patients with IBD was 6.8% (9/132). The incidence of catheter-associated deep venous thrombosis among non-IBD patients was 1.9% (139/7047) (relative risk, 3.5; 95% CI, 1.8-6.6; p < 0.001). The incidence of catheter-associated deep venous thrombosis was increased for patients with malnutrition (4.8%, 30/628, p < 0.001) and increasing age (95% CI, 1.01-1.12; p = 0.02). There was no increased incidence of catheter-associated deep venous thrombosis for patients with diabetes mellitus (1.6%, 25/1574, p < 0.14), malignancy (2.8%, 30/1041, p = 0.06), or tobacco use (1.6%, 31/1938, p = 0.10). After multivariate analysis, IBD, malnutrition, and increasing age were found to be significant risk factors for the development of catheter-associated deep venous thrombosis. LIMITATIONS: The inability to track the number of catheter days, the inaccuracy of administrative data, the lack of outpatient follow-up, and the small number of events in the study cohort were limitations of this study. CONCLUSIONS: This is the first study to demonstrate IBD as an independent risk factor to the development of catheter-associated deep venous thrombosis. The placement of a peripherally inserted central catheter line in IBD should be utilized selectively.

Laparoscopic approach in patients with recurrent Crohn's disease.

The purpose of this study is to review our experience with laparoscopic management of Crohn's disease including patients with prior Crohn's-related abdominal surgery. All cases of Crohn's patients who underwent laparoscopic attempt for management of disease from April 2005 to October 2010 (n = 130) at a single institution were retrospectively reviewed. Evaluated datapoints include: prior abdominal surgery for Crohn's disease, operative time, rate of conversion, and complication rate. Of the 130 patients, 82 (63.1%) patients had no prior abdominal surgery and 48 (36.9%) patients had previous bowel surgery with mean age of 35.3 (3.5-79) and 41.3 (15-66) years, respectively. Operative time with no prior surgery was 106 (23-245) minutes, and with prior surgery was 100 (26-229) minutes. Estimated blood loss with no prior surgery was 116 (5-800) mL, and with prior surgery was 123 (5-800) mL. Conversion from laparoscopic to open surgery in those with no prior surgery was 17.1 per cent and in those with prior surgery, 20.8 per cent (P = 0.64). Postoperative complications were found in 13 patients (15.9%) without prior abdominal surgery and 13 patients (27.1%) with prior surgery (P = 0.17). The most common postoperative complication in both groups was infection/abscess (8.5%). The laparoscopic management of recurrent Crohn's disease is a safe and technically feasible option, even in those patients with prior history of Crohn's-related abdominal surgery, with a low complication rate and low conversion rate. The utility of the laparoscopic approach in Crohn's patients faced with repeat abdominal procedures may be beneficial in the long-term and should be considered as a method to limit morbidity.

Extra nuchal-type fibroma associated with elastosis, traumatic neuroma, a rare APC gene missense mutation, and a very rare MUTYH gene polymorphism: a case report and review of the literature*.

We report a case of an extra nuchal-type fibroma in a 51-year-old male suspected to have attenuated familial adenomatous polyposis (Gardner's syndrome), who presented with a longstanding buttock mass excised due to enlargement and pain. Histopathologically, lobules of haphazard, hypocellular, hyalinized collagen bundles replaced the dermis and subcutis and entrapped nerve bundles, mimicking Morton neuroma. Ramifying nerve twigs found around larger nerve fascicles showed the co-existence of traumatic neuroma. Elastic tissue stain revealed elastosis characterized by large, arborizing fibers lying between and within the hyalinized collagen bundles. Modified Masson's trichrome stain showed light blue staining of collagen bundles producing the hyalinized nodules with irregular, light red staining of collagen bundles at their periphery and within tumor collagen. Compression and/or degeneration of collagen and secondary elastosis with later entrapment by tumor collagen could explain this microscopic phenotype. By immunohistochemistry, tumor spindle cells expressed nuclear ß-catenin and cyclin D1, mostly within regions of fibrosis implicating activation of the adenomatous polyposis coli (APC)-Wnt pathway. Genetic analysis showed a missense mutation in APC gene (c.7504G>A, p.G2502S in exon 15) and a functional homozygous polymorphism in the MUTYH gene (c.36+325G>C, (IVS1+5G/C)). Nuchal-type fibroma has been associated with Gardner's syndrome and trauma. In this patient, genetic predisposition coupled with repetitive, localized trauma and collagen degeneration may have provided the stimulus for the development of extra nuchal-type fibroma.

The effect of diabetes mellitus on surgical site infections after colorectal and noncolorectal general surgical operations.

Patients undergoing colorectal surgery (CRS) are known to be at increased risk of surgical site infection (SSI). We assessed the effect of diabetes and other risk factors on SSI in patients undergoing CRS and patients undergoing general surgery (GS). American College of Surgeons National Surgical Quality Improvement Program Participant Use Data File from 2005 to 2006 was used. Chi2 tests, t tests, and logistic regression were used to assess the risk factors. Of the 129,909 study patients 10.1 per cent were patients undergoing CRS. The incidence of SSI in patients undergoing CRS was 3.8 times higher (95% CI, 3.6-4.1) than in patients undergoing GS. The incidence of SSI was higher in diabetics than nondiabetics in patients undergoing CRS (15.4 vs. 11.0%, P < 0.001) and patients undergoing GS (5.3 vs. 3.1%, P < 0.001). The significant univariate predictors of SSI for patients undergoing GS and patients undergoing CRS were: males, American Society of Anesthesiologists (ASA) class, diabetes emergency surgery, operation time, and greater than 2 units of intraoperative red blood cell transfusion. For patients undergoing GS, increasing age was also significant. After multivariate adjustment, significant predictors of SSI for patients undergoing GS and patients undergoing CRS were: male gender, diabetes, ASA class, emergency surgery, and operation time. For patients undergoing GS, age also remained significant. Among patients undergoing CRS, insulin-dependent diabetes mellitus (IDDM) and noninsulin-dependent diabetes mellitus (NIDDM) were 1.32 (P < 0.05) times more likely than nondiabetics to develop SSI. Among patients undergoing GS, only IDDM (OR, 1.39; P < 0.001) were at increased risk. In this large hospital-based study, patients undergoing CRS were three times more likely to get SSI than patients undergoing GS. Diabetic patients with CRS (IDDM and NIDDM) and patients undergoing GS (IDDM) were at increased risk of SSI compared with nondiabetics. More intense glycemic control may reduce SSI in patients undergoing CRS with diabetes.
