Management, Functional Outcomes, and Quality of Life After Development of Pelvic Sepsis in Patients Undergoing Re-Do Ileal Pouch Anal Anastomosis.

BACKGROUND: The data on management and outcomes of pelvic sepsis after re-do IPAA are scarce. OBJECTIVE: The aim of this study is to report our management algorithm of pelvic sepsis in the setting of re-do IPAA and compare functional outcomes and quality of life after successful management of pelvic sepsis with a no sepsis control group. DESIGN: This is a retrospective cohort study. SETTINGS: This investigation is based on a single academic practice group experience on re-do IPAA. PATIENTS: Patients who underwent re-do IPAA for ileal pouch failure between September 2016 and September 2020 were included in the study. MAIN OUTCOME MEASURES: Management of pelvic sepsis was reported. Functional outcomes, restrictions, and quality-of-life scores were compared between the sepsis and no sepsis groups. RESULTS: One-hundred ten patients were included in our study, of whom 25 (22.7%) developed pelvic sepsis. Twenty-three patients presented with pelvic sepsis before ileostomy closure, and 2 patients presented with pelvic sepsis after ileostomy closure. There were 6 pouch failures in the study period due to pelvic sepsis. Our management was successful in 79% of the patients with median follow-up of 26 months. Treatments included interventional radiology abscess drainage (n = 7), IV antibiotics alone (n = 5), interventional radiology drainage and mushroom catheter placement (n = 1), mushroom catheter placement (n = 1), and endoluminal vacuum-assisted closure (n = 1). Average number of bowel movements, urgency, incontinence, pad use, and seepage were comparable between the pelvic sepsis and no pelvic sepsis groups ( p > 0.05). Lifestyle alterations, Cleveland Global Quality of Life scores, and happiness with the results of the surgery were similar ( p > 0.05). LIMITATIONS: This study is limited by its low study power and limited follow-up time. CONCLUSIONS: Pelvic sepsis is common after re-do IPAA, and management varies according to the location and size of the abscess/sinus. If detected early, our management strategy was associated with high pouch salvage rates. See Video Abstract at http://links.lww.com/DCR/B823 .

Operative, long-term and quality of life outcomes after salvage of failed re-do ileal pouch anal anastomosis.

AIM: Approximately 20%-40% of the patients with re-do ileal pouch anal anastomosis (IPAA) experience pouch failure. Salvage surgery can be attempted in this patient group with severe aversion to permanent ileostomy. The literature regarding secondary IPAA revision after re-do IPAA failure is scarce. METHODS: All patients who underwent a secondary IPAA revision after re-do IPAA failure between September 2016 and July 2021 in a single centre were included. Short- and long-term outcomes and quality of life in this patient group are reported. RESULTS: Ten patients who had secondary IPAA revision for re-do IPAA failure were included. All patients had ulcerative colitis. Nine of these patients had pelvic sepsis and one patient had a mechanical issue. Mucosectomy and handsewn anastomosis was performed in nine patients. The existing pouch was salvaged in six patients and four patients had pouch excision and re-creation. Two patients had postoperative pelvic sepsis. Pouch retention rate was 78% in a median of 28 months. None of the patients had short-gut syndrome. The procedure was associated with good quality of life (median Cleveland Global Quality of Life Index 0.8). All patients would undergo the same surgery if needed. CONCLUSION: Secondary IPAA revision after a failed re-do IPAA can be an option in patients with severe aversion to permanent ileostomy if re-do IPAA fails and it is associated with good outcomes. This patient group should be carefully evaluated and referred to specialized centres if required.

Prevalence, Indirect Costs, and Risk Factors for Work Disability in Patients with Crohn's Disease at a Tertiary Care Center in Rio de Janeiro.

BACKGROUND AND AIMS: Crohn's disease (CD) can lead to work disability with social and economic impacts worldwide. In Brazil, where its prevalence is increasing, we assessed the indirect costs, prevalence, and risk factors for work disability in the state of Rio de Janeiro and in a tertiary care referral center of the state. METHODS: Data were retrieved from the database of the Single System of Social Security Benefits Information, with a cross-check for aid pension and disability retirement. A subanalysis was performed with CD patients followed up at the tertiary care referral center using a prospective CD database, including clinical variables assessed as possible risk factors for work disability. RESULTS: From 2010 to 2018, the estimated prevalence of CD was 26.05 per 100,000 inhabitants, while the associated work disability was 16.6%, with indirect costs of US$ 8,562,195.86. Permanent disability occurred more frequently in those aged 40 to 49 years. In the referral center, the prevalence of work disability was 16.7%, with a mean interval of 3 years between diagnosis and the first benefit. Risk factors for absence from work were predominantly abdominal surgery, anovaginal fistulas, disease duration, and the A2 profile of the Montreal classification. CONCLUSIONS: In Rio de Janeiro, work disability affects one-sixth of CD patients, and risk factors are associated with disease duration and complications. In the context of increasing prevalence, as this disability compromises young patients after a relatively short period of disease, the socioeconomic burden of CD is expected to increase in the future.

Pouch abandonment is extremely rare even in the reoperative setting: A high-volume referral center experience.

BACKGROUND: Ileal pouch anal anastomosis is the preferred method for restoration of intestinal continuity after proctocolectomy. Successful ileal pouch anal anastomosis requires adequate reach of the ileal mesentery to the pelvis. Reach issues are a common cause for intraoperative pouch abandonment; however, data regarding contemporary abandonment rates are rare and nonexistent in the revisional setting. METHODS: A retrospective review was conducted of consecutive ileal pouch anal anastomosis surgery at a single referral center. Both initial or "primary" pouches and revisional pouch surgery were included. RESULTS: In total, 447 attempts at pouch anal anastomosis were made, with an 1.6% overall rate of intraoperative abandonment. Pouch abandonment was attributed to inadequate mesenteric reach during 3 surgeries, desmoid tumors in 2 surgeries, and insufficient remaining small bowel in 2 surgeries. Twelve patients required lengthening maneuvers including 6 S pouches (1%) and 6 H pouches (1%). One half (49%) of operations were revisional ileal pouch anal anastomosis surgery. Overall, reach issues led to intraoperative abandonment in only 0.4% of attempted primary pouches and 1.0% of revisional surgeries. A preoperative diagnosis of familial adenomatous polyposis was associated with pouch abandonment (P < .001). CONCLUSION: Extremely low pouch abandonment rates as a result of mesenteric reach can be achieved even in the revisional setting at a high-volume center with institutional expertise. In the revisional setting, intra-abdominal desmoids or the potential for short gut affects pouch abandonment rates as much as reach issues.

Stapled End-To-Side Ileocolic Anastomosis in Crohn's Disease: Old Dog, Reliable Tricks? A Retrospective Two-Center Cohort Study.

Objective: Analyze our long-term experience with a less-popularized but stalwart approach, the stapled end-to-side ileocolic anastomosis. Background: The choice of technical approach to ileocolic anastomosis after ileocecal resection for Crohn's disease affects surgical outcomes and recurrence. Yet, despite heterogeneous data from different anastomotic configurations, there remains no clear guidance as to the optimal technique. Methods: In a retrospective cohort design, patients undergoing ileocolic anastomosis in the setting of Crohn's disease between 2016 and 2021 at two institutions were identified. Patient characteristics and surgical outcomes in terms of recurrence (surgical, clinical, and endoscopic) were studied. Results: In total, 211 patients were included. Before surgery, 80% were exposed to at least 1 cycle of systemic steroids and 71% had at least 1 biologic agent; 60% exhibited penetrating disease and 38% developed an intra-abdominal abscess. After surgery, one anastomosis leaked (0.5%). Over 2.4 years of follow-up (IQR = 1.3-3.9), surgical recurrence was 0.9%. Two-year overall recurrence-free and endoscopic recurrence-free survivals were 74% and 85% (95% CI = 68-81 and 80-91), respectively. The adjusted hazard ratio of endoscopic recurrence was 3.0 (95% CI = 1.4-6.2) for males and 5.2 (1.2-22) for patients who received systemic steroids before the surgery. Conclusion: The stapled end-to-side anastomosis is an efficient, reliable, and reproducible approach to maintain bowel continuity after ileocecal resection with durable outcomes. Our outcomes demonstrate low rates of disease recurrence and stand favorably in comparison to other more technically complex or protracted anastomotic approaches. This anastomosis is an ideal reconstructive approach after ileocecal resection for Crohn's disease.

Geosocial Features and Loss of Biodiversity Underlie Variable Rates of Inflammatory Bowel Disease in a Large Developing Country: A Population-Based Study.

BACKGROUND: The epidemiology of inflammatory bowel disease (IBD) in developing countries may uncover etiopathogenic factors. We investigated IBD prevalence in Brazil by investigating its geographic, spatial, and temporal distribution, and attempted to identify factors associated with its recent increase. METHODS: A drug prescription database was queried longitudinally to identify patients and verify population distribution and density, race, urbanicity, sanitation, and Human Development Index. Prevalence was calculated using the number of IBD patients and the population estimated during the same decade. Data were matched to indices using linear regression analyses. RESULTS: We identified 162 894 IBD patients, 59% with ulcerative colitis (UC) and 41% with Crohn's disease (CD). The overall prevalence of IBD was 80 per 100 000, with 46 per 100 000 for UC and 36 per 100 000 for CD. Estimated rates adjusted to total population showed that IBD more than triplicated from 2008 to 2017. The distribution of IBD demonstrated a South-to-North gradient that generally followed population apportionment. However, marked regional differences and disease clusters were identified that did not fit with conventionally accepted IBD epidemiological associations, revealing that the rise of IBD was variable. In some areas, loss of biodiversity was associated with high IBD prevalence. CONCLUSIONS: When distribution is considered in the context of IBD prevalence, marked regional differences become evident. Despite a background of Westernization, hotspots of IBD are recognized that are not explained by population density, urbanicity, sanitation, or other indices but apparently are explained by biodiversity loss. Thus, the rise of IBD in developing countries is not uniform, but rather is one that varies depending on yet unexplored factors like geoecological conditions.

The analysis of a large population of inflammatory bowel disease (IBD) patients in a developing country reveals that the rising prevalence of IBD is not uniform and is linked to factors not traditionally associated with IBD, such as geosocial features and loss of biodiversity.

Pathologic complete response after neoadjuvant treatment for rectal cancer decreases distant recurrence and could eradicate local recurrence.

BACKGROUND: The aim of this study was to evaluate the clinical implications of pathologic complete response (pCR) (i.e., T0N0M0) after neoadjuvant chemoradiation and radical surgery in patients with locally advanced rectal cancer. MATERIALS AND METHODS: A single-center, prospectively maintained colorectal cancer database was queried for patients with primary cII and cIII rectal cancer staged by CT and ERUS/MRI undergoing long-course neoadjuvant chemoradiation followed by proctectomy with curative intent between 1997 and 2007. Patients were stratified into pCR and no-pCR groups and compared with respect to demographics, tumor and treatment characteristics, and oncologic outcomes. Outcomes evaluated were 5-year overall survival, disease-free survival, disease-specific mortality, local recurrence, and distant recurrence. RESULTS: The query returned 238 patients (73% male), with a median age of 57 years and median follow-up of 54 months. Of these, 58 patients achieved pCR. Patients with pCR vs no-pCR were statistically comparable with respect to demographics, chemoradiation regimens, tumor distance from anal verge, clinical stage, surgical procedures performed, and follow-up time. No patient with pCR had local recurrence. Overall survival and distant recurrence were also significantly improved for patients achieving pCR. CONCLUSIONS: Achievement of pCR after neoadjuvant chemoradiation is associated with greatly improved cancer outcomes in locally advanced rectal cancer. Future studies should evaluate the relationship between increases in pCR rates and improvements in cancer outcomes in this population.

Laparoscopic resection for rectal cancer: a case-matched study.

INTRODUCTION: The field of laparoscopic rectal cancer surgery is expanding. We compare short-term and early oncological outcomes after laparoscopic versus open resection in carefully matched rectal cancer patients. METHODS: All consecutive patients undergoing elective laparoscopic resection for rectal cancer were reviewed. Laparoscopic resections were matched 1:1 to open resections by age, gender, American Society of Anesthesiologists class, body mass index, neoadjuvant chemoradiation, and type of surgery. Data were analyzed using Fisher's exact, chi-square, Wilcoxon rank-sum tests, and Kaplan-Meier estimates. P-value <0.05 was considered statistically significant. RESULTS: Ninety-one rectal cancer patients with laparoscopic resection were included, 59% were male, and median age was 62 years. Conversion rate was 18.7%. Laparoscopic and open surgery had similar 30-day morbidity and mortality except wound infection, which was lower for the laparoscopic group (p = 0.02). Laparoscopic surgery had similar 30-day readmissions but shorter total length of hospital stay (5 versus 7 days, p < 0.01), time to first flatus (3 versus 4.5 days, p = 0.001), and time to first bowel movement (4 versus 5 days, p = 0.05) when compared with open surgery. The 3-year disease-free survival, local recurrence, and distant recurrence rates were also similar between the two groups. CONCLUSION: Laparoscopic surgery can be safely performed for rectal cancer, with better postoperative recovery and acceptable early oncological outcomes. Results from large ongoing randomized trials with longer follow-up time are pending to better define oncologic outcomes.

Factors associated with septic complications after restorative proctocolectomy.

OBJECTIVE: Few studies have evaluated factors that may be associated with the development of septic complications after restorative proctocolectomy. Therefore, the aim of this study is to evaluate preoperative and operative factors that might be associated with septic complications after restorative proctocolectomy. METHODS: Patients developing abdominal and pelvic septic complications after restorative proctocolectomy were identified from a prospective database. Patients with subclinical leaks and ileostomy closure leak were not included in the septic complication group. A multivariable logistic regression model for sepsis was constructed using a forward stepwise selection with entry criterion of P < 0.05. RESULTS: From 1983 to 2007, 3233 patients (56% male) were included in the database. Eight-four percent (2597) of patients underwent proximal diversion. Two hundred patients (6.2%) developed septic complications within 3 months of restorative proctocolectomy or within 3 months of ileostomy closure. On multivariate analysis, body mass index > 30 (P = 0.02, OR = 1.77), final pathologic diagnosis of ulcerative/indeterminate colitis (P = 0.02, OR = 2) or Crohn's disease (P = 0.02, OR = 3.6), intraoperative (P = 0.02, OR = 1.6), and postoperative transfusions (P = 0.01, OR = 1.9) were all independently associated with septic complications. We also demonstrated an independent association among individual surgeons (P = 0.04) with decreased septic complications. CONCLUSIONS: Body mass index greater than 30, final pathologic diagnosis of ulcerative/indeterminate colitis or Crohn's disease, intraoperative and postoperative transfusions, and surgeon were all independent factors associated with septic complications after restorative proctocolectomy.

Downstaging without complete pathologic response after neoadjuvant treatment improves cancer outcomes for cIII but not cII rectal cancers.

BACKGROUND: The aim of this study was to evaluate whether downstaging impacts prognosis in patients with cII versus cIII rectal cancer. MATERIALS AND METHODS: We identified from our colorectal cancer database 295 patients with primary cII and cIII rectal cancer staged by CT and ERUS/MRI who received 5-FU-based chemoradiation followed by R0 surgery after a median interval of 7 weeks during 1997-2007. The median radiotherapy dose was 5040 cGy. We excluded 58 patients with pathologic complete response (pCR) and compared among the remaining 162 patients pathologic downstaging (cII to ypI, cIII to ypII or ypI) versus no pathologic downstaging (c stage < or = yp stage). Outcomes evaluated were 5-year overall survival, 3-year cancer-specific survival, disease-free survival, overall recurrence, local recurrence, and distant recurrence. RESULTS: The median age was 58 years and median follow-up was 48 months. Patients with downstaging versus no downstaging were statistically comparable with respect to demographics, chemoradiation regimen, interval time between neoadjuvant chemoradiation and surgery, tumor distance from anal verge, surgical procedures performed, and follow-up time. With the exception of local recurrence rates, downstaging resulted in significantly improved cancer outcomes for cIII but not cII. CONCLUSIONS: Downstaging without pCR is a significant prognostic factor for patients with stage cIII rectal cancer. Tumor response to neoadjuvant chemoradiation should be taken into account when defining the optimal adjuvant chemotherapy regimen for patients with cIII rectal cancer.

Laparoscopic versus open colectomy for patients with American Society of Anesthesiology (ASA) classifications 3 and 4: the minimally invasive approach is associated with significantly quicker recovery and reduced costs.

BACKGROUND: Conceivably, the benefits of earlier recovery associated with a minimally invasive technique used in laparoscopic colectomy (LC) may be amplified for patients with comorbid disease. The dearth of evidence supporting the safety of laparoscopy for these patients led to a comparison of outcomes between LC and open colectomy (OC) for patients with American Society of Anesthesiology (ASA) classifications 3 and 4. METHODS: Data for all ASA 3 and 4 patients who underwent elective LC were reviewed from a prospectively maintained laparoscopic database. The patients who underwent LC were matched with OC patients by age, gender, diagnosis, year, and type of surgery. Estimated blood loss, operation time, time to return of bowel function, length of hospital stay, readmission rate, and 30-day complication and mortality rates were compared using chi-square, Fisher's exact, and Wilcoxon tests as appropriate. A p value <0.05 was considered statistically significant. RESULTS: In this study, 231 LCs were matched with 231 OCs. The median age of the patients was 68 years, and 234 (51%) of the patients were male. There were 44 (19%) conversions from LC to OC. More patients in the OC group had undergone previous major laparotomy (5 vs. 15%; p < 0.001). Estimated blood loss, return of bowel function, length of hospital stay, and total direct costs were decreased in the LC group. Wound infection was significantly greater with OC (p = 0.02). When patients with previous major laparotomy were excluded, the two groups had similar overall morbidity. The other benefits of LC, however, persisted. CONCLUSION: The findings show that LC is a safe option for patients with a high ASA classification. The LC approach is associated with faster postoperative recovery, lower morbidity rates, and lower hospital costs than the OC approach.

The evolution of prophylactic colorectal surgery for familial adenomatous polyposis.

INTRODUCTION: Over the past 50 years, prophylactic colorectal surgery for patients with familial adenomatous polyposis has evolved as new technologies and ideas have emerged. The aim of this study was to review all the index surgeries for familial adenomatous polyposis performed at our institution to assess the changes in surgical techniques. METHODS: All index abdominal surgeries for polyposis from 1950 to 2007 were identified through the Polyposis Registry Database. We assigned the patients to prepouch (before 1983), pouch (after 1983), and laparoscopic (after 1991) eras, and analyzed the changes in prophylactic surgery. RESULTS: Four hundred twenty-four patients were included; 51% were male. Median age at surgery was 26 (range, 9-66) years. In the prepouch era, 97% (66 of 68) of all surgeries and 100% of restorative surgeries were ileorectal anastomosis. After 1983, 70% (54 of 77) of patients with a severe phenotype had an ileal pouch-anal anastomosis. After 1991, 110 operations (43%) were laparoscopic (88 ileorectal and 22 ileal pouch-anal anastomosis). CONCLUSION: Colon surgery for familial adenomatous polyposis has evolved as advances in surgical technique have created more options to reduce the risk of cancer. Current strategy uses polyposis severity and distribution to decide on the surgical option, and laparoscopy to minimize morbidity.

Outcomes of Crohn's disease presenting with abdominopelvic abscess.

PURPOSE: The aim of this study was to evaluate clinical outcomes, quality-adjusted life-years, and the cost-effectiveness gained from percutaneous drainage followed by elective surgery vs. initial surgery for abdominopelvic abscesses related to Crohn's disease. METHODS: All consecutive patients with spontaneous Crohn's disease-related abdominopelvic abscess from 1997 to 2007 were reviewed. The authors excluded postoperative and perirectal abscesses. Decision analysis during one year of patient life was used to calculate quality-adjusted life-years and the cost-effectiveness of each strategy. RESULTS: Of 94 patients, 48 (51 percent) were initially approached with percutaneous drainage. Thirty-one (65 percent) had successful percutaneous drainage and delayed elective surgery. The factors significantly associated with percutaneous drainage failure were steroid use, colonic phenotype, and multiple or multilocular abscesses. The initial treatment was surgery in the remaining 46 (49 percent) patients. The initial approach with percutaneous drainage gave higher quality-adjusted life-years and was more cost-effective than initial surgery. Percutaneous drainage was the optimal strategy in spite of the risk of failure and septic complications within the plausible range. CONCLUSIONS: Percutaneous drainage failure is associated with steroid use, colonic phenotype, and multiple or multilocular abscesses. When feasible, percutaneous drainage is the most effective strategy from the perspective of patients and third-party payers.

Laparoscopic surgery for patients with Crohn's colitis: a case-matched study.

INTRODUCTION: The purpose of this study was to compare short and long-term outcomes of laparoscopic colectomy with open colectomy in patients with Crohn's disease confined to the colon. MATERIALS AND METHODS: We reviewed all patients undergoing laparoscopic colectomy for Crohn's disease at our institution between 1994 and 2005. Laparoscopic colectomies were matched to open colectomies by patient age, gender, American Society of Anesthesiologists score, type, and year of surgery. We excluded patients with concomitant small bowel disease. RESULTS: Twenty-seven laparoscopic cases were matched with 27 open cases. There were seven conversions (26%). There was no mortality. Median operative times were significantly longer after laparoscopic colectomy (240 vs 150 min, P < 0.01), and estimated blood loss was comparable (325 vs 350 ml, P = 0.4). Postoperative complications were similar. Laparoscopic colectomies had shorter median length of stay (5 vs 6 days, P = 0.07) and median time to first bowel movement (3 vs 4 days, P = 0.4). When overall length of stay included 30-day readmissions, the difference in favor of laparoscopy became statistically significant (P = 0.02). Recurrent disease requiring surgery was decreased after laparoscopy, although median follow-up was significantly shorter. CONCLUSION: Laparoscopic colectomy is a safe and acceptable option for patients with Crohn's colitis. Longer follow-up is needed to accurately establish recurrence rates.

Perianal complete remission with combined therapy (seton placement and anti-TNF agents) in Crohn's disease: a Brazilian multicenter observational study.

BACKGROUND: Perianal fistulizing Crohn's disease is one of the most severe phenotypes of inflammatory bowel diseases. Combined therapy with seton placement and anti-TNF therapy is the most common strategy for this condition. OBJECTIVES: The aim of this study was to analyze the rates of complete perianal remission after combined therapy for perianal fistulizing Crohn's disease. METHODS: This was a retrospective observational study with perianal fistulizing Crohn's disease patients submitted to combined therapy from four inflammatory bowel diseases referral centers. We analyzed patients' demographic characteristics, Montreal classification, concomitant medication, classification of the fistulae, occurrence of perianal complete remission and recurrence after remission. Complete perianal remission was defined as absence of drainage from the fistulae associated with seton removal. DISCUSSION: A total of 78 patients were included, 44 (55.8%) females with a mean age of 33.8 (±15) years. Most patients were treated with Infliximab, 66.2%, than with Adalimumab, 33.8%. Complex fistulae were found in 52/78 patients (66.7%). After a medium follow-up of 48.2 months, 41/78 patients (52.6%) had complete perianal remission (95% CI: 43.5%-63.6%). Recurrence occurred in four (9.8%) patients (95% CI: 0.7%-18.8%) in an average period of 74.8 months. CONCLUSIONS: Combined therapy lead to favorable and durable results in perianal fistulizing Crohn's disease.

Neoadjuvant therapy for rectal cancer: the impact of longer interval between chemoradiation and surgery.

PURPOSE: The aim of this study was to determine the effect of a longer interval between neoadjuvant chemoradiation and surgery on perioperative morbidity and oncologic outcomes. METHODS: A colorectal cancer database was queried for clinical stage II and III rectal cancer patients undergoing neoadjuvant chemoradiation followed by proctectomy between 1997 and 2007. The neoadjuvant regimen consisted of long course external beam radiation and 5-fluorouracil chemotherapy. Patients with inflammatory bowel disease, hereditary cancer, extracolonic malignancy, urgent surgery, or non-validated treatment dates were excluded. Patients were divided into two groups according to the interval between chemoradiation and surgery (<8 and ≥ 8 weeks). Perioperative complications and oncologic outcomes were compared. RESULTS: One hundred seventy-seven patients were included. Groups were comparable with respect to demographics, tumor, and treatment characteristics. Perioperative complications were not affected by the interval between chemoradiation and surgery. Patients undergoing surgery ≥ 8 weeks after chemoradiation experienced a significant improvement in pathologic complete response rate (30.8% vs. 16.5%, p = 0.03) and had decreased 3-year local recurrence rate (1.2% vs. 10.5%, p = 0.04). A Cox regression analysis was performed to assess the compounding effect of a complete pathologic response on oncologic outcome. A longer interval correlated with less local recurrence, although statistical significance was not reached (p = 0.07). CONCLUSION: An interval between chemoradiation and surgery ≥ 8 weeks is safe and is associated with a higher rate of pathologic complete response and decreased local recurrence.

Ileorectal anastomosis and proctocolectomy with end ileostomy for ulcerative colitis.

Until the development of the ileal pouch-anal anastomosis in the early 1980s, proctocolectomy with end ileostomy was the only definitive surgery for ulcerative colitis and colectomy with ileorectal anastomosis was the procedure of choice for affected patients who were reluctant to have a permanent ileostomy. Currently, ileal pouch-anal anastomosis is the most common procedure for patients with ulcerative colitis requiring surgical treatment. However, there is still a role for ileorectal anastomosis and proctocolectomy with end ileostomy for a selected group of patients. In this review, the authors summarize the current indications for ileorectal anastomosis and proctocolectomy with end ileostomy in patients with ulcerative colitis.

Does CT influence the decision to perform colectomy in patients with severe ulcerative colitis?

PURPOSE: The purpose of this study was to evaluate the impact of abdominal computerized tomography (CT) on the decision to perform colectomy in patients with severe acute ulcerative colitis (SAC). METHODS: Patients with SAC admitted to a single hospital between 2002 and 2007 were reviewed. The criteria for SAC were > or =6 bloody bowel movements per day plus fever >37.8 degrees C, pulse >90, or hemoglobin <10.5 g/dL. Study patients were given a SAC score of 2-4 based on these criteria. Clinical and laboratory parameters, medication use, abdominal X-ray, and endoscopic findings in SAC patients who did or did not have an abdominal CT were compared. Chi-squared, Fisher exact test, and Wilcoxon rank sum test were used as appropriate. RESULTS: Ninety-two consecutive patients with SAC were evaluated. CT was performed in 26 (28%). The SAC score, laboratory values, abdominal X-ray, and endoscopic findings were similar in patients who did or did not have a CT. Colectomy was performed in 32 (48%) and 10 (38%) patients who did or did not have a CT, respectively (p = 0.4). The CT findings were similar in patients who required colectomy and those who did not require colectomy. In two (8%) of the patients who underwent CT, the CT findings clearly influenced the decision to perform or defer colectomy. CONCLUSION: CT has a minor impact on the decision to perform colectomy in patients with severe acute ulcerative colitis.

CT enterography for Crohn's disease: accurate preoperative diagnostic imaging.

PURPOSE: CT enterography (CTE) is a technique that provides detailed images of the small bowel by using a low Hounsfield unit oral contrast media. This study was designed to correlate CTE findings with operative findings in patients with Crohn's disease. METHODS: We performed a retrospective study of all patients with Crohn's disease of the small bowel or colon, who had CTE and subsequent small bowel or colon surgery within three months after the CT examination. CTE findings of stricture, fistula, inflammatory mass, abscess, and combinations of these abnormalities were compared with operative findings. Specialist radiologists and fellowship-trained colorectal surgeons participated in the study. The Fisher's exact test or chi-squared tests were used with respect to categorical data, and the Wilcoxon's rank-sum test was used for quantitative data. RESULTS: In 36 patients, the presence or absence of stricture, fistula, abscess, or inflammatory mass was correctly determined by CTE in 100, 94, 100, and 97 percent, respectively. The accuracy for stricture or fistula number was 83 and 86 percent, respectively. There were nine patients with multiple disease phenotypes identified on CTE of which eight were confirmed at surgery. CTE overestimated or underestimated the extent of disease in 11 patients (31 percent). CONCLUSIONS: CTE is an accurate preoperative diagnostic imaging study for small-bowel Crohn's disease. The ability of this imaging study to detect both luminal and extraluminal pathology is a distinct advantage of CTE compared with small-bowel contrast studies.
