Timing of readmissions for complications following emergency colectomy: follow-up beyond post-operative day 30 matters. Surg Endosc 2024; 38:2240-2251. [PMID: 38503906 PMCID: PMC10978660 DOI: 10.1007/s00464-024-10724-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 01/28/2024] [Indexed: 03/21/2024]
Abstract
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.

Extended versus limited mesenteric excision for operative Crohn's disease: 30-Day outcomes from the ACS-NSQIP database. Int J Colorectal Dis 2023; 38:268. [PMID: 37978997 DOI: 10.1007/s00384-023-04561-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
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.

Abstract
BACKGROUND Low anterior resection syndrome (LARS) is a well-described consequence of rectal cancer treatment. Studying the degree to which bowel dysfunction exists in the general population may help to better interpret to what extent LARS is related to disease and/or cancer treatment. Currently, North American LARS normative data are lacking. The aim of this study was to describe the prevalence of bowel dysfunction, as measured by the LARS score, and quality of life (QoL) in a reference North American sample. Quality of life was measured and associations between participant characteristics and LARS were identified. STUDY DESIGN This was a single-institution cross-sectional study of asymptomatic adults who underwent screening and surveillance colonoscopies from 2018 to 2021 with no/benign endoscopic findings. Survey was conducted on select comorbidities, sociodemographic factors, LARS, and QoL. Outcomes were LARS and QoL. Multivariable linear regression accounting for a priori clinical factors associated with bowel dysfunction was performed. RESULTS Of 1,004 subjects approached, 502 (50.0%) participated, and 135 (26.9%) participants had major/minor LARS. On multiple linear regression, female sex (β = 2.15, 95% CI 0.30 to 4.00), younger age (β = -0.10, 95% CI -0.18 to -0.03), White ethnicity (β = 2.45, 95% CI 0.15 to 4.74), and the presence of at least one of the following factors: diabetes, depression, neurologic disorder, or cholecystectomy (β = 3.54, 95% CI 1.57 to 5.51) were independently associated with a higher LARS score. Individuals with LARS had lower global QoL, functional subscales, and various symptom subscale scores. CONCLUSIONS Our study identified the baseline prevalence of LARS in asymptomatic adults who have not undergone a low anterior resection. These normative data will allow for more accurate interpretation of ongoing studies on LARS in North American rectal cancer patients.

Is the Hartmann's procedure for diverticulitis obsolete? National trends in colectomy for diverticulitis in the emergency setting from 1993 to 2018. Surg Endosc 2023; 37:7717-7728. [PMID: 37563342 DOI: 10.1007/s00464-023-10317-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 07/17/2023] [Indexed: 08/12/2023]
Abstract
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.

Abstract
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.

Abstract
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.

Patient and surgeon preferences for early ileostomy closure following restorative proctectomy for rectal cancer: why aren't we doing it? Surg Endosc 2023; 37:669-682. [PMID: 36195816 DOI: 10.1007/s00464-022-09580-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 08/25/2022] [Indexed: 01/18/2023]
Abstract
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.

The impact of delaying colonoscopies during the COVID-19 pandemic on colorectal cancer detection and prevention. Surg Endosc 2022; 36:9364-9373. [PMID: 35428894 PMCID: PMC9012515 DOI: 10.1007/s00464-022-09211-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 01/25/2022] [Indexed: 02/06/2023]
Abstract
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.

Oral Antibiotic Bowel Preparation Prior to Urgent Colectomy Reduces Odds of Organ Space Surgical Site Infections: a NSQIP Propensity-Score Matched Study. J Gastrointest Surg 2022; 26:2193-2200. [PMID: 36002788 DOI: 10.1007/s11605-022-05440-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 08/10/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND Preoperative administration of oral antibiotic bowel preparation (OABP) alone has been shown to reduce infectious outcomes in patients undergoing elective colectomy. However, it remains unclear if these benefits extend to the emergency setting. This is a retrospective, propensity-score matched study comparing 30-day perioperative morbidity between those who received OABP alone versus no preparation prior to urgent colectomy. METHODS Using the American College of Surgeons National Surgical Quality Improvement Program database, adults undergoing urgent colectomy from 2012 to 2019 were included. Those who were clinically obstructed or who received mechanical bowel preparation were excluded. Outcomes of interest included: surgical site infection (SSI), leak, ileus, and major morbidity. RESULTS Of 24,559 patients meeting inclusion criteria, 878 (3.6%) received OABP prior to urgent colectomy. Prior to matching, those receiving no preparation were more likely to have higher ASA class, diabetes, hypertension, preoperative sepsis, open procedures, and a dirty wound classification. After matching, 1756 patients, remained with 878 in each arm. Preoperative characteristics were balanced on univariate analysis. Postoperatively, patients receiving OABP experienced decreased organ space SSI (11.2% vs. 15.5%, p = 0.009) and ileus (30.3% vs. 35.3%, p = 0.029), with no difference in leak rates (3.3% vs 3.3%, p = 1.000) or NSQIP major morbidity (47.4% vs. 49.9%, p = 0.316). On multivariate logistic regression, including propensity score, the reduction in organ space SSI associated with OABP persisted (OR 0.684, 95% CI 0.516-0.903). CONCLUSION OABP prior to select urgent colectomies was associated with fewer organ space SSIs and may be considered when feasible.

Early discharge after colorectal cancer resection: trends and impact on patient outcomes. Surg Endosc 2022; 36:6617-6628. [PMID: 34988738 DOI: 10.1007/s00464-021-08923-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 11/20/2021] [Indexed: 01/02/2023]
Abstract
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.

Bowel stimulation before loop ileostomy closure to reduce postoperative ileus: a multicenter, single-blinded, randomized controlled trial. Surg Endosc 2022; 37:3934-3943. [PMID: 35984521 PMCID: PMC9390101 DOI: 10.1007/s00464-022-09510-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 07/26/2022] [Indexed: 11/24/2022]
Abstract
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.

Abstract
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.

Observational versus antibiotic therapy for acute uncomplicated diverticulitis: A non-inferiority meta-analysis based on a Delphi consensus. Surgery 2022; 171:328-335. [PMID: 34344525 DOI: 10.1016/j.surg.2021.07.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 07/03/2021] [Accepted: 07/12/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND The purpose of this study was to determine if observational therapy is noninferior to antibiotics for acute uncomplicated diverticulitis according to clinically relevant margins. METHODS MEDLINE, EMBASE, and Cochrane were systematically searched by 2 independent reviewers to identify comparative studies of observational therapy versus antibiotics for acute uncomplicated diverticulitis. Non-inferiority margins (ΔNI) for each outcome were based on Delphi consensus including 50 patients and 55 physicians: persistent diverticulitis (ΔNI = 4.0%), progression to complicated diverticulitis (ΔNI = 3.0%), and time to recovery (ΔNI = 5 days). Risk differences and mean differences were pooled using random-effects meta-analysis. One-sided 90% confidence intervals and Z-tests were used to determine non-inferiority. A sensitivity analysis was performed, excluding patients post hoc determined to have complicated diverticulitis. RESULTS Nine studies (3 randomized controlled trials, 6 observational studies) met inclusion criteria: observational therapy (n = 2,011) versus antibiotics (n = 1,144). Observational therapy was noninferior to antibiotics regarding the risk of persistent diverticulitis (pooled risk differences: -0.39%, 90% CI -3.22 to 2.44%, ΔNI: 4.0%, PNI < 0.001; I2 = 66%) and progression to complicated diverticulitis (pooled risk differences: -0.030%, 90% CI -0.99 to 0.92%, ΔNI: 3.0%, PNI < 0.001; I2 = 0%). On sensitivity analysis, observational therapy remained noninferior for both outcomes. When stratified by study design, observational therapy also remained noninferior for both outcomes among randomized controlled trials only. Only 1 study reported on time to recovery as a continuous outcome, with no statistical difference between antibiotics and observational therapy. CONCLUSION According to clinically relevant ΔNIs, observational therapy was noninferior to antibiotics for the treatment of acute uncomplicated diverticulitis with regard to persistent diverticulitis and progression to complicated diverticulitis.

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. Surg Endosc 2022; 36:5652-5659. [PMID: 34973078 PMCID: PMC9283142 DOI: 10.1007/s00464-021-08926-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 11/22/2021] [Indexed: 12/02/2022]
Abstract
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.

Assessment of long-term bowel dysfunction after restorative proctectomy for neoplastic disease: A population-based cohort study. Surgery 2021; 172:782-788. [PMID: 34848073 DOI: 10.1016/j.surg.2021.10.068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 10/20/2021] [Accepted: 10/31/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND The purpose of this study was to describe postoperative bowel dysfunction after restorative proctectomy, and to identify factors associated with its development. METHODS Patients who underwent restorative proctectomy for rectal cancer between April 1998 and November 2018 were identified from the Hospital Episode Statistics database and linked to the Clinical Practice Research Datalink for postoperative follow-up. Bowel dysfunction was defined according to relevant symptom-based read codes and medication prescription-product codes. A Cox proportional hazards model was performed to identify factors associated with postoperative bowel dysfunction, adjusting for relevant covariates. RESULTS In total, 2,197 patients were included. The median age was 70.0 (interquartile range: 62.0-77.0) years old, and the majority (59.2%) of patients were male. After a median follow-up of 51.6 (24.0-90.0) months, bowel dysfunction was identified in 620 (28.2%) patients. Risk factors for postoperative bowel dysfunction included extremes of age (<40 years old: adjusted hazards ratio 2.35, 95% confidence interval 1.18-4.65; 70-79 years old: adjusted hazards ratio 1.25, 95% confidence interval 1.03-1.52), radiotherapy (adjusted hazards ratio 1.94, 95% confidence interval 1.56-2.42), distal tumors (adjusted hazards ratio 1.62, 95% confidence interval 1.34-1.94), history of diverting ostomy (adjusted hazards ratio 1.58, 95% confidence interval 1.33-1.89), and anastomotic leak (adjusted hazards ratio 1.48, 95% confidence interval 1.06-2.05). A minimally invasive surgical approach was protective for postoperative bowel dysfunction (adjusted hazards ratio 0.68, 95% confidence interval 0.53-0.86). CONCLUSION Bowel dysfunction was common after restorative proctectomy, and several patient, disease, and treatment-level factors were associated with its development.

Abstract
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. Colorectal Dis 2021; 23:1248-1257. [PMID: 33638278 DOI: 10.1111/codi.15602] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 01/15/2021] [Accepted: 02/21/2021] [Indexed: 12/15/2022]
Abstract
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.

Reasons for delay in timely administration of adjuvant chemotherapy for patients with stage III colon cancer: a multicentre cohort study from the McGill University Department of Oncology. BMJ Open Qual 2021; 10:bmjoq-2020-000934. [PMID: 33685857 PMCID: PMC7942255 DOI: 10.1136/bmjoq-2020-000934] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 01/29/2021] [Accepted: 02/22/2021] [Indexed: 11/03/2022] Open
Abstract
PURPOSE Adjuvant chemotherapy within 56 or 84 days following curative resection is globally accepted as the standard of care for stage III colon cancer as it has been associated with improved overall survival. Initiation of adjuvant chemotherapy within this time frame is therefore recommended by clinical practice guidelines, including the European Society for Medical Oncology. The objective of this study was to evaluate adherence to these clinical practice guidelines for patients with stage III colon cancer across the Rossy Cancer Network (RCN); a partnership of McGill University's Faculty of Medicine, McGill University Health Centre, Jewish General Hospital and St Mary's Hospital Center. PATIENTS AND METHODS 187 patients who had been diagnosed with stage III colon cancer and received adjuvant chemotherapy within the RCN partner hospitals from 2012 to 2015 were included. Patient and treatment information was retrospectively determined by chart review. Χ2 and Wilcoxon rank-sum tests were used to measure associations and a multivariate Cox regression model was used to determine risk factors contributing to delays in administration of adjuvant chemotherapy. RESULTS The median turnaround time between surgery and adjuvant chemotherapy was 69 days. Importantly, only 27% of patients met the 56-day target, and 71% met the 84-day target. Increasing age, having more than one surgical complication and being diagnosed between 2013-2014 and 2014-2015 reduced the likelihood that patients met these targets. Furthermore, delays were observed at most intervals from surgery to first adjuvant chemotherapy treatment. CONCLUSION Our study found that within these academic hospital settings, 27% of patients met the 56-day target, and 71% met the 84-day target. Delays were associated with hospital, surgeon and patient-related factors. Initiatives in quality improvement are needed in order to improve adherence to recommended treatment guidelines for prompt administration of adjuvant chemotherapy for stage III colon cancer.

The quality, suitability, content and readability of online health-related information regarding sexual dysfunction after rectal cancer surgery. Colorectal Dis 2021; 23:376-383. [PMID: 33404140 DOI: 10.1111/codi.15514] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 12/06/2020] [Accepted: 12/28/2020] [Indexed: 02/08/2023]
Abstract
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.

Development and Validation of a Clinical Risk Score for Intensive Care Resource Utilization After Colon Cancer Surgery: a Practical Guide to the Selection of Patients During COVID-19. J Gastrointest Surg 2021; 25:252-259.

Abstract
BACKGROUND The purpose of this study was to develop and validate a prediction model and clinical risk score for Intensive Care Resource Utilization after colon cancer surgery. METHODS Adult (≥ 18 years old) patients from the 2012 to 2018 ACS-NSQIP colectomy-targeted database who underwent elective colon cancer surgery were identified. A prediction model for 30-day postoperative Intensive Care Resource Utilization was developed and transformed into a clinical risk score based on the regression coefficients. Model performance was assessed using the area under the receiver operating characteristic curve (AUC) and Hosmer-Lemeshow goodness-of-fit test. The model was validated in a separate test set of similar patients. RESULTS In total, 54,893 patients underwent an elective colon cancer resection, of which 1224 (2.2%) required postoperative Intensive Care Resource Utilization. The final prediction model retained six variables: age (≥ 70; OR 1.90, 95% CI 1.68-2.14), sex (male; OR 1.73, 95% CI 1.54-1.95), American Society of Anesthesiologists score (III/IV; OR 2.52, 95% CI 2.15-2.95), cardiorespiratory disease (yes; OR 2.22, 95% CI 1.94-2.53), functional status (dependent; OR 2.81, 95% CI 2.22-3.56), and operative approach (open surgery; OR 1.70, 95% CI 1.51-1.93). The model demonstrated good discrimination (AUC = 0.73). A clinical risk score was developed, and the risk of requiring postoperative Intensive Care Resource Utilization ranged from 0.03 (0 points) to 19.0% (8 points). The model performed well on test set validation (AUC = 0.73). CONCLUSION A prediction model and clinical risk score for postoperative Intensive Care Resource Utilization after colon cancer surgery was developed and validated.

Abstract
BACKGROUND Randomized studies have shown low compliance to adjuvant chemotherapy in rectal cancer patients receiving preoperative chemotherapy and external beam radiation (CT/EBRT) with total mesorectal excision. We hypothesize that giving neoadjuvant CT before local treatment would improve CT compliance. METHODS Between 2010-2017, 180 patients were randomized (2:1) to either Arm A (AA) with FOLFOX x6 cycles prior to high dose rate brachytherapy (HDRBT) and surgery plus adjuvant FOLFOX x6 cycles, or Arm B (AB), with neoadjuvant HDRBT with surgery and adjuvant FOLFOX x12 cycles. The primary endpoint was CT compliance to ≥85% of full-dose CT for the first six cycles. Secondary endpoints were ypT0N0, five-year disease free survival (DFS), local control and overall survival (OS). RESULTS Patients were randomized to either AA (n = 120, median age (MA) 62 years) or AB (n = 60, MA 63 years). 175/180 patients completed HDRBT as planned (97.2%). In AA, two patients expired during CT; three patients post-randomization received short course EBRT because of progression under CT (n = 2, AA) or personal preference (n = 1, AB). ypT0N0 was 31% in AA and 28% in AB (p = 0.7). CT Compliance was 80% in AA and 53% in AB (p = 0.0002). Acute G3/G4 toxicity was 35.8% in AA and 27.6% in AB (p = 0.23). With a median follow-up of 48.5 months (IQR 33-72), the five-year DFS was 72.3% with AA and 68.3% with AB (p = 0.74), the five-year OS 83.8% for AA and 82.2% for AB (p = 0.53), and the five-year local recurrence was 6.3% for AA and 5.8% for AB (p = 0.71). CONCLUSION We confirmed improved compliance to neoadjuvant CT in this study. Although there is no statistical difference in ypT0N0 rate, local recurrence, and DFS between the two arms, a trend towards favourable oncological outcomes is observed.

Abstract
BACKGROUND Rates of colectomy for ulcerative colitis have been decreasing, particularly since the advent of biologics, but the subsequent impact of reduced colectomy rates on the development of neoplasms in chronically treated ulcerative colitis colons is unknown. PURPOSE To determine trends in colectomy for colorectal neoplasms in adult patients with ulcerative colitis. METHODS Adult admissions with ulcerative colitis were identified from the National Inpatient Sample from 1993 to 2015. The rate of colectomy with concurrent colorectal neoplasm served as the primary outcome and was evaluated using time trend linear and multivariable regression. RESULTS There were 366,286 admissions with ulcerative colitis including 16,556 (4.5%) total colectomies. Of those undergoing colectomy, 2018 (12.2%) had a concurrent diagnosis of colorectal neoplasm. The proportion of colectomies for ulcerative colitis with concurrent colorectal neoplasm increased from 10.3 to 12.5% (pTrend = 0.004). Specifically, the proportion of colectomies performed for dysplasia/benign neoplasm and rectal cancer increased from 3.5 to 5.6% (pTrend < 0.001) and from 2.6 to 3.0% (pTrend = 0.028) respectively, and those for colon cancer remained stable (4.5 to 3.9%, pTrend = 0.423). On multivariate regression, year of colectomy was a significant predictor of colectomy for colorectal neoplasm (OR = 1.044, 95% CI = 1.025-1.062). DISCUSSION Operative management of ulcerative colitis appears to be slowly increasing in oncological indications. The rising proportions of colectomies performed for colorectal neoplasms suggest the need for continued screening in these patients, including rectal surveillance.

Diverting loop ileostomy versus total abdominal colectomy for clostridioides difficile colitis: outcomes beyond the index admission. Surg Endosc 2020; 35:3147-3153.

Abstract
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.

Abstract
INTRODUCTION Low anterior resection syndrome (LARS) is described as disordered bowel function after rectal resection that leads to a detriment in quality of life, and affects the majority of individuals following restorative proctectomy for rectal cancer. The management of LARS includes personalised troubleshooting and effective self-management behaviours. Thus, affected individuals need to be well informed and appropriately engaged in their own LARS management. This manuscript describes the development of a LARS patient-centred programme (LPCP) and the study protocol for its evaluation in a randomised controlled trial. METHODS AND ANALYSIS This will be a multicentre, randomised, assessor-blind, parallel-groups, pragmatic trial evaluating the impact of an LPCP, consisting of an informational booklet, patient diaries and nurse support, on patient-reported outcomes after restorative proctectomy for rectal cancer. The informational booklet was developed by a multidisciplinary LARS team, and was vetted in a focus group and semistructured interviews involving patients, caregivers, and healthcare professionals. The primary outcome will be global quality of life (QoL), as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (QLQ-C30), at 6 months after surgery. The treatment effect on global QoL will be modelled using generalised estimating equations. Secondary outcomes include symptom change, patient activation, bowel function measures, emotional distress, knowledge about LARS and satisfaction with the LPCP.

Image Guided Adaptive Endorectal Brachytherapy in the Nonoperative Management of Patients With Rectal Cancer. Int J Radiat Oncol Biol Phys 2019; 105:1005-1011. [PMID: 31476417 DOI: 10.1016/j.ijrobp.2019.08.042] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 08/20/2019] [Accepted: 08/20/2019] [Indexed: 02/07/2023]
Abstract
PURPOSE Organ preservation or nonoperative management of rectal cancer is of growing interest. Image guided adaptive endorectal brachytherapy is a radiation dose escalation modality: we explored its role in elderly patients unfit for surgery and patients refusing surgery. METHODS AND MATERIALS In this registry study, patients with rectal cancer who were ineligible for surgery received 40 Gy in 16 fractions of pelvic external beam radiation therapy. They subsequently received 3 weekly image guided adaptive brachytherapy boosts of 10 Gy to the residual tumor, for a total of 30 Gy in 3 fractions. Complete clinical response (cCR) and local control were the primary endpoints. RESULTS 94 patients were included; the median age was 81.1 years. With a median follow-up of 1.9 years, the proportion of cCR was 86.2%, the tumor regrowth proportion was 13.6%, and the cumulative incidence of local relapse was 2.7% at 1 year and 16.8% at 2 years. When considering responders and nonresponders, the 2-year local control was 71.5%. The overall survival at 2 years was 63.6%. Acute rectal grade 1 to 2 toxicity included all patients: 12.8% of patients had late bleeding requiring iron replacement, blood transfusions, or argon plasma therapy. CONCLUSIONS Results of this registry study, evaluating radiation dose escalation for elderly medically unfit patients with unselected tumors, reveal that a high proportion of patients achieved cCR with a manageable toxicity profile. This technology will likely contribute to the challenging nonoperative management paradigm of rectal cancer.

Abstract
INTRODUCTION Postoperative ileus (POI) is regarded as the most clinically significant morbidity following loop ileostomy closure; however, its incidence remains poorly understood. Our objective was therefore to determine the pooled incidence of POI after loop ileostomy closure and identify risk factors associated with its development. METHODS We systematically searched MEDLINE (via Ovid and PubMed), Embase, the Cochrane Library, Biosis Previews, and Scopus to identify studies reporting the incidence of POI in patients who underwent loop ileostomy closure. Two independent reviewers extracted data and appraised study quality. Cumulative incidence proportions were pooled across studies using a random-effects meta-analytic model. RESULTS Sixty-seven studies, including 9528 patients, met our inclusion criteria. The pooled estimate of POI was 8.0% (95% CI 6.9-9.3%; I2 = 74%). The estimated incidence varied by POI definition: studies with a robust definition of POI (n = 8) demonstrated the highest estimate of POI (12.4%, 95% CI 9.2-16.5%; I2 = 79%) while studies that did not report an explicit POI definition (n = 38) demonstrated the lowest estimate (6.7%, 95% CI 5.3-8.3%; I2 = 61%). Small bowel anastomosis technique (hand-sewn) and interval time from ileostomy creation to closure (longer time) were the factors most commonly associated with POI after loop ileostomy closure. However, most comparative studies were not powered to examine risk factors for POI. CONCLUSIONS POI is an important complication after loop ileostomy closure, and its incidence is dependent on its definition. More research aimed at studying this complication is required to better understand risk factors for POI after loop ileostomy closure.

A Comparison of Pathologic Outcomes of Open, Laparoscopic, and Robotic Resections for Rectal Cancer Using the ACS-NSQIP Proctectomy-Targeted Database: a Propensity Score Analysis. J Gastrointest Surg 2019; 23:348-356.

Abstract
BACKGROUND There is ongoing debate regarding the benefits of minimally invasive techniques for rectal cancer surgery. The aim of this study was to compare pathologic outcomes of patients who underwent rectal cancer resection by open surgery, laparoscopy, and robotic surgery using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) proctectomy-targeted database. METHODS All patients from the 2016 ACS-NSQIP proctectomy-targeted database who underwent elective proctectomy for rectal cancer were identified. Patients were divided into three groups based on initial operative approach: open surgery, laparoscopy, and robotic surgery. Pathologic and 30-day clinical outcomes were then compared between the groups. A propensity score analysis was performed to control for confounders, and adjusted odds ratios for pathologic outcomes were reported. RESULTS A total of 578 patients were included-211 (36.5%) in the open group, 213 (36.9%) in the laparoscopic group, and 154 (26.6%) in the robotic group. Conversion to open surgery was more common among laparoscopic cases compared to robotic cases (15.0% vs. 6.5%, respectively; p = 0.011). Positive circumferential resection margin (CRM) was observed in 4.7%, 3.8%, and 5.2% (p = 0.79) of open, laparoscopic, and robotic resections, respectively. Propensity score adjusted odds ratios for positive CRM (open surgery as a reference group) were 0.70 (0.26-1.85, p = 0.47) for laparoscopy and 1.03 (0.39-2.70, p = 0.96) for robotic surgery. CONCLUSIONS The use of minimally invasive surgical techniques for rectal cancer surgery does not appear to confer worse pathologic outcomes.

Abstract
BACKGROUND This study aimed to define the incidence and risk factors of postoperative morbidity and mortality after pouch excision (PE). METHODS ACS-NSQIP database was queried for patients who underwent PE between 2005 and 2015. Main outcome measures were 30-day mortality, major morbidity, overall surgical site infections (SSI), reoperation, and length of stay (LOS). Risk factors associated with these outcomes were assessed using multivariate logistic or quantile regression. RESULTS Three hundred eighty-one patients underwent PE (mean age 47.7(±15.3) years; 51.7% female). Mean body mass index (BMI) was 24.6(±5.7) kg/m2, 55.4% were ASA class 1-2 and 18.4% were immunosuppressed. Mean operative time was 252(±112.7) min, 98% were elective cases, and median LOS was 7(5-11) days. Twenty-eight percent experienced major morbidity, including SSIs (21.5% overall, 9.2% superficial, 3.7% deep, 10.3% organ space), sepsis (9.5%), urinary tract infection (5.8%), and postoperative pneumonia (2.4%). The observed venous thromboembolism rate was low, with 0.5 and 0.8% of patients suffering pulmonary embolism and deep vein thrombosis, respectively; 5.5% required reoperation. Postoperative mortality was 0.8%. On multivariate logistic regression, smoking (OR 3.03 [95% CI 1.56, 5.88]) and operative time (OR 1.003 [95% CI 1.0003, 1.0005) were associated with increased odds of major morbidity. Smoking (OR 3.29 [95% CI 1.65, 6.54]) and operative time (OR 1.002 [95% CI 1.000, 1.004]) were independent risk factors for overall SSI. LOS was significantly increased in patients with major morbidity (3.29 days [95% CI 1.60, 4.99]) and increased operative time (0.013 days [95% CI 0.007, 0.018]). CONCLUSIONS PE is an operation with significant risk of morbidity. However, mortality was low in the present cohort of patients. Patients who were smokers and had longer operative time had increased risk of overall infectious complications and major morbidity. Furthermore, major morbidity and operative time were associated with increased hospital length of stay following PE.

Abstract
This study queried American Society of Colon and Rectal Surgeons members for management of sigmoid volvulus and aimed to determine whether surgeon experience impacts decision-making. American Society of Colon and Rectal Surgeons members received a 16-item survey in March, 2017. Items included endoscopic detorsion technique and colonic decompression, preoperative dietary considerations, surgical approach, and respondents’ demographics. Respondents were separated into low experience (LE; ≤10 years in practice) and high experience (HE; >10 years in practice). Of 1996 survey recipients, 10 per cent (197) responded; 124 were HE and 73 were LE. Most were fellowship-trained (93.8%) and primarily in colorectal surgery practice (74.6%), however only 27.4 per cent managed >20 sigmoid volvulus cases as attendings. Fifty-two per cent use rectal tubes for continued colonic decompression after successful endoscopic detorsion; 81.2 per cent would perform sigmoid colectomy on the index admission after successful detorsion, but within a variable timeframe (one to seven days postdetorsion) and with variable dietary restrictions in the interval period; 49.7 per cent would perform a laparoscopic colectomy and 68.3 per cent would perform a stapled colorectal anastomosis. LE surgeons reported a higher proportion of gastrointestinal-performed endoscopic detorsions (P = 0.015), were more likely allow regular diet in the interval period (P = 0.031), and were more inclined to use laparoscopy (P = 0.008), versus HE surgeons. There remains controversy among many of the components in the management of sigmoid volvulus after successful endoscopic detorsion.

Abstract
BACKGROUND The short-term benefits of laparoscopy for rectal surgery are equivocal. The objective of this study was to determine the clinical and economic impact of an enhanced recovery pathway (ERP) for laparoscopic and open rectal surgery. MATERIALS AND METHODS All patients who underwent elective rectal resection with primary anastomosis between January 2009 and March 2012 at two tertiary-care, university-affiliated institutions were identified. Patients who met inclusion criteria were divided into four groups, according to surgical approach (laparoscopic [lap] or open) and perioperative management (ERP or conventional care [CC]). Length of stay (LOS), postoperative complications, and hospital costs were compared. RESULTS A total of 381 patients were included in the analysis (201 open-CC, 34 lap-CC, 38 open-ERP, and 108 lap-ERP). Patients were mostly similar at baseline. ERPs significantly reduced median LOS after both open cases (open-CC 10 days versus open-ERP 7.5 days, P = .003) and laparoscopic cases (lap-CC 5 days versus lap-ERP 4.5 days, P = .046). ERPs also reduced variability in LOS compared with CC. There was no difference in postoperative complications with the use of ERPs (open-CC 51% versus open-ERP 50%, P = .419; lap-CC 32% versus lap-ERP 36%, P = .689). On multivariate analysis, both ERP (-3.6 days [95% confidence interval, CI -6.0 to -1.3]) and laparoscopy (-3.6 days [95% CI -5.9 to -1.0]) were independently associated with decreased LOS. Overall costs were only lower when lap-ERP was compared with open-CC (mean difference -2420 CAN$ [95% CI -5628 to -786]). CONCLUSIONS ERPs reduced LOS after rectal resections, and the combination of laparoscopy and ERPs significantly reduced overall costs compared to when neither strategy was used.

Abstract
BACKGROUND Laparoscopic colorectal cancer operations in obese patients pose technical challenges that may negatively impact oncologic adequacy. A meta-analysis was performed to assess the oncologic outcomes of laparoscopic colorectal cancer resections in obese compared to non-obese patients. Short- and long-term outcomes were assessed secondarily. METHODS A systematic literature search was conducted from inception until October 01, 2014. Studies that compared outcomes of laparoscopic colorectal malignant neoplasms in obese and non-obese patients were selected for meta-analysis. Studies that defined obesity as body mass index (BMI) ≥ 30 kg/m2 were included. Oncologic, operative, and postoperative outcomes were evaluated. Pooled odds ratios (OR) and weighted mean differences (WMD) with 95 % confidence intervals (CI) were calculated using fixed-effects models. For oncologic and survival outcomes, a subgroup analysis was conducted for rectal cancer and a secondary analysis was conducted for Asian studies that used a BMI cutoff of 25 kg/m2. RESULTS Thirteen observational studies with a total of 4550 patients were included in the meta-analysis. Lymph node retrieval, distal, and circumferential margins, and 5-year disease-free and overall survival were similar in the obese and non-obese groups. Conversion rate (OR 2.11, 95 % CI 1.58-2.81), postoperative morbidity (OR 1.54, 95 % CI 1.21-1.97), wound infection (OR 2.43, 95 % CI 1.46-4.03), and anastomotic leak (OR 1.65, 95 % CI 1.01-2.71) were all significantly increased in the obese group. CONCLUSIONS Laparoscopic colorectal cancer operations in obese patients pose an increased technical challenge as demonstrated by higher conversion rates and higher risk of postoperative complications compared to non-obese patients. Despite these challenges, oncologic adequacy of laparoscopic colorectal cancer resections is comparable in both groups.

Abstract
BACKGROUND Recent attention has been focused on the relationship between carcinoembryonic antigen (CEA) and pathological complete response (pCR), without consensus regarding its predictive value. This study aims to examine the association between CEA and pCR. METHODS We conducted a retrospective review of a prospectively maintained database of all patients who underwent primary rectal cancer resection after neo-adjuvant chemoradiotherapy (nCRT). Patients were divided into two groups, pCR or no-pCR, based on final pathology. CEA levels were measured at the initial visit with the surgeon/oncologist and post-completion of nCRT. RESULTS One hundred and forty-one patients underwent primary rectal cancer resections after nCRT. Nineteen patients (13.5 %) achieved pCR, while 122 (86.5 %) had no-pCR. Pre-nCRT CEA levels were not significantly different between groups (2.75 vs 4.5 μg/L, p = 0.65). However, post-nCRT CEA levels were significantly lower in patients with pCR (1.7 vs 2.4 μg/L, p < 0.01). On multivariate logistic regression analyses, low post-nCRT CEA level was an independent predictor of pCR (OR 1.74, CI 1.06, 3.81) and normalization of CEA from an initially elevated level was a highly significant predictor of pCR (OR 64.8, CI 2.53, 18,371). CONCLUSION Low post-nCRT CEA is an independent predictor of pCR, and normalization of CEA post-nCRT is a strong predictor of pCR.

Abstract
e14615 Background: Use of the anti-diabetic drug Metformin has been associated with reduced risk or improved prognosis of several cancers in both lab models and retrospective population studies of diabetics. Plausible mechanisms of action include (1) reduction in serum levels of insulin or inflammatory cytokines and (2) direct effects on target cells due to action of the drug as an inhibitor of mitochondrial respiration, including activation of AMPK. Methods: Non-diabetic subjects (n = 47) consented to bloodwork and sigmoid biopsy at screening colonoscopy, metformin administration (500 mg TID) for 10 weeks, and end-of-study sigmoid biopsy and bloodwork. Serum assays were performed on both fasting and post standard oral glucose load specimens. Metformin levels were measured by mass spectroscopy. Anti-phospho-histone-3 immunostaining was used to quantify proliferation. Results: Metformin reduced fasting levels of c-peptide, insulin, and IL-6 levels by < 10%, a magnitude of change that laboratory studies suggest is unlikely to be biologically significant. However, postprandial insulin levels following metformin were reduced by 18 % relative to baseline postprandial levels, a finding of potential physiologic relevance. Serum metformin level showed considerable variation between subjects (1005 ± 769 ng/ml) and this variation was not correlated with effects of metformin on epithelial proliferation. Proliferation index fell from 5.9 to 3.3, (p<0.03), a change greater than predicted by in vitro studies of direct action of metformin at the concentrations measured in serum. Conclusions: Metformin lowers insulin levels even in non-diabetic subjects, and post prandial insulin levels are more sensitive indicators of metformin action than fasting biomarkers. As high insulin level has been linked to increased cancer risk and/or worse prognosis (eg J Natl Cancer Inst. 2004;96:546), this systemic action suggests clinical applications. However, direct exposure of colonic epithelial cells to high luminal concentrations of metformin may also be relevant and is one of several factors that may explain the greater inhibitory effect of the drug on colonic epithelium proliferation than that previously reported for breast or prostate.

Abstract
PURPOSE This study evaluated risk factors for mortality after emergency colectomy for fulminant Clostridium difficile infection. METHODS Retrospective study of 130 cases of Clostridium difficile infection that required a colectomy between 1994 and 2007 in four hospitals of Quebec, Canada. Primary outcome was 30-day mortality. RESULTS Twenty-five cases underwent colectomy in 1994 to 2002, 41 in 2003, 40 in 2004, and 24 in 2005 to 2007. Common indications were septic shock (41 percent) and nonresponse to medical treatment (39 percent). Overall, 30-day mortality was 37 percent. Mortality increased with age but was not influenced by comorbidities burden. Mortality correlated with preoperative lactate (< or =2.1 mmol/L: 26 percent; 2.2-4.9 mmol/L: 52 percent; > or =5.0 mmol/L: 75 percent, P < 0.001), leukocytosis (<20.0 x 10(9)/L: 32 percent; 20.0-49.9 x 10(9)/L: 33 percent; > or =50.0 x 10(9)/L: 73 percent, P = 0.008), albumin (> or =25 g/L: 19 percent; 15-24 g/L: 38 percent; <15 g/L: 52 percent, P = 0.04) and renal failure. In multivariate analysis, risk factors for mortality were age (per year, adjusted odds ratio: 1.03, 95 percent confidence interval: 1.00-1.06), preoperative lactate greater than or equal to 5.0 mmol/L (adjusted odds ratio: 10.32, 95 percent confidence interval: 2.59-41.1), leukocytosis greater than or equal to 50.0 x10(9)/L (adjusted odds ratio: 3.68, 95 percent confidence interval: 0.92-14.8) and albumin less than 15 g/L (adjusted odds ratio, 6.57, 95 percent confidence interval: 1.31-33.1). CONCLUSIONS Incidence of Clostridium difficile infection-related emergency colectomies increased 20-fold during the epidemic. Postoperative mortality can be predicted by simple laboratory parameters. Three-fourths of patients with leukocytosis greater or equal to 50.0 x10(9)/L or lactate greater or equal to 5.0 mmol/L died. When possible, emergency colectomy should be performed earlier.

Abstract
PURPOSE This study was designed to determine the results of patients with rectal adenocarcinoma treated with local excision. METHODS A retrospective, chart review was conducted for all patients treated with local excision for rectal adenocarcinoma from 1984 to 1998. RESULTS Sixty-four patients were retained for analysis. The median follow-up was 37 (range, 9-125) months. There were 15 local failures with a median time to local failure of 12 months. Seven patients were salvaged with further operation (4 by repeat local excision, 4 by abdominoperineal resection, and 1 by low anterior resection). The incidence of local recurrence increased with advancing stage of the carcinoma (T1, 13 percent; T2, 24 percent; T3, 71 percent), histologic grade of differentiation, (well, 12 percent; moderately, 24 percent; poorly, 44 percent), and margin status (negative, 16 percent; close (within 2 mm), 33 percent; positive, 50 percent). Sixteen percent of carcinomas < or = 3 cm failed compared with 47 percent for carcinomas > 3 cm. Nine percent (1/11) of T2 patients treated with adjuvant radiation therapy recurred locally compared with 36 percent (5/14) without radiation therapy. Three of four T3 patients who received radiation therapy failed locally compared with two of three who did not. Using the Kaplan-Meier method, the overall survival at five years was 71 percent, and disease-free survival was 83 percent. Actuarial local failure was 27 percent and freedom from distant metastasis was 86 percent. The sphincter preservation rate was 90 percent at five years. CONCLUSIONS Local excision alone is an acceptable option for well-differentiated, T1 carcinomas, < or = 3 cm. Adjuvant radiation is recommended for T2 lesions. The high local recurrence rate in patients after local excision of T3 lesions with or without adjuvant radiotherapy would mandate a radical resection.

Abstract
PURPOSE The value of specialization has frequently been challenged by many health care institutions and providers. This review was conducted to determine whether there were any outcome differences in the management of fistulas complicating diverticulitis. METHODS We conducted an historical cohort study using hospital charts of all cases of fistulas complicating diverticulitis that were operated on in four university-affiliated hospitals between 1975 and 1995. There were 122 patients, with 37 under the care of fully trained colorectal surgeons and 85 under the care of general surgeons. RESULTS There were no significant differences in patient demographics, preoperative comorbidities, or the number of preoperative diagnostic investigations between the two groups. The colorectal surgeons performed more intraoperative ureteral stenting (Colorectal Surgery 55.5 percent vs. General Surgery 24.4 percent, P = 0.001). The general surgeons performed more initial diverting Hartmann's and colostomy procedures (Colorectal Surgery 5.4 percent vs. General Surgery 27 percent, P = 0.013). The patients in the General Surgery group had longer preoperative lengths of stay (median Colorectal Surgery 3 (range, 1-28) days vs. General Surgery 8 (range, 0-29) days; P < 0.001), longer postoperative lengths of stay (median Colorectal Surgery 11 (range, 5-40) days vs. General Surgery 14 (range, 2-80) days; P = 0.001), and longer total lengths of stay (median Colorectal Surgery 14 (range, 6-62) days vs. General Surgery 24 (range, 6-100) days; P < 0.001). The patients in the General Surgery group experienced a higher rate of wound infections (Colorectal Surgery 5.4 percent vs. General Surgery 12.9 percent), and a larger proportion of them experienced complications (Colorectal Surgery 27 percent vs. General Surgery 41.2 percent). CONCLUSIONS We conclude that specialization in colon and rectal surgery contributed to an improved outcome, with a lower rate of diverting procedures, a shorter hospital stay, and a lower rate of complications.

Abstract
Colonic lipoma with a dramatic presentation requiring urgent operation is a rare occurrence. We report two such cases in conjunction with a review of the literature on colonic lipomata. Clinicopathologic features of two patients who required urgent resection were studied. The preoperative diagnosis of colonic lipoma was suggested on imaging study in one case. A MEDLINE search was conducted with a special goal of revealing cases with a dramatic presentation. One patient presented with rectal bleeding and intussusception related to a partially infarcted 4.5-cm submucosal lipoma of the lower descending colon. The second patient presented with intestinal obstruction related to a near-totally infarcted 6-cm submucosal lipoma at the splenic flexure. In both cases a florid reactive vascular and fibro-/myofibroblastic proliferation and associated hyperplastic mucosal pattern were present at the base and edge of the lipoma. Among 275 previously reported cases of colonic lipoma 28 patients had a dramatic presentation with pain and/or rectal bleeding being the most significant prodromal symptom. In this subset the lipomas tended to be larger, frequently had associated marked necrosis/ulceration, and were less likely to be located in the ascending colon/cecum. Whereas colonic lipomas are relatively common occasional cases present dramatically with massive bleeding, intussusception, or even perforation for which emergency operation is required. Such lipomas usually reveal marked ischemic changes.

Abstract
OBJECTIVE To describe the etiology and clinical course of acute colitis occurring after flexible endoscopy. DESIGN Chart review. SETTING A university teaching hospital. PATIENTS Eight patients who sought assessment of potential colonic disease. INTERVENTION Colonoscopy in 5 patients and flexible sigmoidoscopy in 3 patients. The indication for endoscopy was screening in 5 patients, cancer surveillance in 2 patients and preoperative evaluation of colon carcinoma in 1 patient. OUTCOME MEASURES The relation of presenting symptoms to glutaraldehyde exposure, the response to therapy and the need for further therapy. RESULTS All patients had abdominal pain, mucus diarrhea and rectal bleeding within 48 hours after endoscopy. Most patients reported that the symptoms started within 12 hours of the procedure. All patients were confirmed by sigmoidoscopy to have colitis within 72 hours of the first endoscopic procedure. One patient required hospitalization. In the first 7 patients several stool cultures were negative for Clostridium difficile using the cytotoxin assay by the cell culture method. Four patients had negative cultures for Yersinia, Salmonella and Shigella spp. Three patients were treated with metronidazole initially. Two patients underwent endoscopic biopsy and examination of the biopsy specimen showed fibrinoleukocytic exudate and ischemic type injury. One patient underwent the scheduled sigmoid resection within 48 hours of endoscopy for a Dukes' stage B adenocarcinoma. Concomitant acute ischemic colitis limited to the mucosa and submucosa was noted in the resected specimen. Symptoms resolved in all patients and follow-up endoscopy revealed normal mucosa. CONCLUSION The entity of glutaraldehyde-induced colitis should be recognized and special attention should be given during instrument cleansing to minimize the risk of its development.

Abstract
OBJECTIVE To determine the rate of complications of ileoanal pouch anastomosis, their treatment and their influence on a successful outcome. DESIGN A computerized database and chart review. SETTING Three academic tertiary care health centres. PATIENTS All 239 patients admitted for surgery between 1981 and 1994 with a diagnosis of ulcerative colitis and familial adenomatosis coli. INTERVENTIONS Sphincter-saving total proctocolectomy and construction of either S-type of J-type ileoanal reservoir. OUTCOME MEASURES Indications, early and late complications, incidence of pouch excision. RESULTS Of the 239 patients, 228 (95.4%) were operated on for ulcerative colitis and 11 (4.6%) for familial polyposis coli. One patient in each group was found to have a carcinoma not previously diagnosed. Twenty-eight patients had poor results: in 17 (7.1%) the ileostomy was never closed or was re-established because of pelvic sepsis or complex fistulas, sclerosing cholangitis or severe diarrhea; 11 (4.6%) patients required excision of the pouch because of anal stenosis, perirectal abscess-fistula or rectovaginal fistula. Three patients died--of suicide, and complications of liver transplantation and HIV infection. Thus, 208 patients maintained a functioning pouch. The early complication rate (within 30 days of operation) was 57.7% (138 patients) and the late complication rate was 52.3% (125 patients). Pouchitis alone did not lead to failure or pouch excision. Emptying difficulties in 25 patients with anal stenosis were helped in 2 by resorting to intermittent catheterization. Patients with indeterminate colitis had a higher rate of anorectal septic complications, and all patients having Crohn's disease after pouch construction had complicated courses. CONCLUSIONS The complication rate associated with ileoanal pouch anastomosis continues to be relatively high despite increasing experience with this technique. Overall, however, a satisfactory outcome was obtained in 87% of patients.

Abstract
This study was undertaken to assess the appropriate management of patients with diverticulitis complicated by fistula formation. A retrospective chart review was conducted on patients with symptoms of a fistula who presented between 1975 to 1995. There were 42 patients (32 women, 76%; 10 men, 24%) who ranged in age from 46 to 89 years (mean 69.8 +/- 9.8). Six patients had multiple fistulas. The types of fistulas included colovesical (48%), colovaginal (44%), colocutaneous (4%), colotubal (2%), and coloenteric (2%). Operative procedures consisted of resection and primary anastomosis in 38 patients and a Hartmann's operation in one. Three patients were managed conservatively with antibiotics (two due to poor performance status, the third due to resolution of symptoms). There were no operative deaths. The postoperative course was uncomplicated in 69%, while 12 patients (31%) experienced 19 complications (40%). These consisted of urinary tract infection (9.5%), atelectasis (7.1%), prolonged ileus (4.8%), arrhythmias (4.8%) and renal failure, myocardial infarction, pseudomembranous colitis, peroneal nerve palsy, unexplained fever, pulmonary edema (2.4% each). There were no anastomotic leaks and no deaths. Hospital stay ranged from 6 to 31 days (mean 12.3 +/- 7.6). Fistulas due to diverticulitis were safely managed by resection and primary anastomosis without mortality and with acceptable morbidity in this series. Patients deemed to be poor operative risks can be managed with a course of nonoperative treatment.

Abstract
To determine if subtotal colectomy constitutes a valuable alternative in the treatment of patients with chronic constipation, a retrospective review of 52 consecutive patients who underwent subtotal colectomy between January 1980 and August 1985 was undertaken. Forty-six patients underwent ileodistal sigmoidostomy while five patients underwent ileoproctostomy and five with concomitant rectal prolapse underwent simultaneous proctopexy. A mortality rate of 3.8 percent and morbidity rate of 60 percent were encountered. The most frequently occurring complication was small-bowel obstruction, which occurred in 36 percent, and necessitated laparotomy in 66 percent. Additional procedures were necessary in five patients because of newly discovered rectal prolapse (two patients), rectocele (one patient), unrelieved constipation (one patient), and incapacitating incontinence (one patient). Follow-up data available in 94 percent (mean, 46 months) disclosed that patients had an average of 2.8 bowel movements per day without the use of laxatives (89 percent) or enemas (80 percent). Overall, 79 percent were satisfied with the final outcome. It is concluded that subtotal colectomy constitutes a viable option in the treatment of chronic constipation. However, the significant morbidity and mortality associated with the procedure dictate the need for careful patient selection on the basis of appropriate physiologic testing.
