Sepsis is a major predictor of failure after ileal pouch-anal anastomosis

Rediversion of the Failing Ileoanal Pouch: First Step in Pouch Salvage?

BACKGROUND

Ileal pouch-anal anastomosis is a technically demanding procedure with many potential complications. Rediversion with an ileostomy is often the first step in pouch salvage; however, it may not be clear if an individual patient will undergo subsequent pouch salvage surgery. We aimed to describe the indications and short- and long-term outcomes of rediversion in our pouch registry.

METHODS

We queried our institutional pouch registry for patients who underwent index 2- or 3-stage IPAA and subsequent rediversion at our institution between 1985 and 2022. Pouches constructed elsewhere, rediverted elsewhere, or those patients who underwent pouch salvage/excision without prior rediversion were excluded. Patients were selected for pouch salvage according to the surgeon's discretion.

RESULTS

Overall, 177 patients (3.4% of 5207 index pouches) were rediverted. At index pouch, median patient age was 32 years and 50.8% were women. Diagnoses included ulcerative colitis (86.4%), indeterminate colitis (6.2%), familial adenomatous polyposis (4.0%), and others (3.4%). Median time from prior ileostomy closure to rediversion was 7.2 years. Indications for rediversion were inflammatory in 98 (55.4%) and noninflammatory in 79 (44.6%) patients. After rediversion, 52% underwent pouch salvage, 30% had no further surgery, and 18.1% underwent pouch excision. The 5-year pouch survival rates for inflammatory and noninflammatory indications were 71.5% and 94.5%, respectively (P = .02).

CONCLUSION

Rediversion of ileoanal pouches is a safe initial strategy to manage failing pouches and is a useful first step in pouch salvage in many patients. Subsequent salvage surgery for noninflammatory indications had a significantly higher pouch salvage rate than those rediverted for inflammatory complications.

Temporary loop end ileostomy reduces the risk of stoma outlet obstruction: a comparative clinical study in patients undergoing restorative proctocolectomy and ileal pouch-anal anastomosis

PURPOSE

Stoma outlet obstruction (SOO) is a serious complication of restorative proctocolectomy (RPC) and ileal pouch-anal anastomosis (IPAA). When the ileal mesentery to the pouch is under excessive tension, the ileum near the ileostomy twists easily, causing SOO. Loop-end ileostomy (EI) for fecal diversion was introduced in 2021 to prevent SOO, and we aimed to verify whether temporary EI reduces the incidence of SOO in RPC and IPAA patients relative to loop ileostomy (LI).

METHODS

This study included 106 consecutive RPC and IPAA patients with a diverting ileostomy and categorized them into LI (n = 75) or EI (n = 31) groups. The clinical characteristics of the patients were analyzed and compared.

RESULTS

Patient characteristics were similar between the groups, except for higher preoperative steroid use in the LI group (38.7%; p = 0.0116). There were no significant differences between the groups in anatomical factors, such as abdominal wall thickness and the height-adjusted distance between the root of the superior mesenteric artery and the bottom of the external anal sphincter. There were no significant differences in surgery-related factors, with ≥ 90% of the patients in each group undergoing laparoscopic procedures. A multivariate logistic regression analysis revealed that EI significantly reduced the risk of SOO relative to LI (OR, 0.18; 95% CI 0.03-0.92; p = 0.0399).

CONCLUSION

EI reduced SOO levels after RPC and IPAA and may be beneficial for cases in which anastomosis is challenging.

Third Time's the Charm? Indications and Outcomes for Redo-Redo IPAA

BACKGROUND

Up to 20% to 40% cases of redo IPAA procedures will result in pouch failure. Whether to offer a second redo procedure to maintain intestinal continuity remains a controversial decision.

OBJECTIVE

To report our institutional experience of second redo IPAA procedures.

DESIGN

This was a retrospective review. Patient-reported outcomes were compared between patients undergoing second redo procedures and those undergoing first redo procedures using propensity score matching to balance the 2 cohorts.

SETTINGS

Tertiary referral center.

PATIENTS

Patients who underwent second redo IPAA procedures between 2004 and 2021 were included in this study.

INTERVENTIONS

Second redo IPAA.

MAIN OUTCOME MEASURES

Pouch survival and patient-reported outcomes were measured using the Cleveland Global Quality of Life survey.

RESULTS

Twenty-three patients were included (65% women), 20 (87%) with an index diagnosis of ulcerative colitis and 3 (13%) with indeterminate colitis. The final diagnosis was changed to Crohn's disease in 8 (35%) cases. The indication for pouch salvage was the same for the first and second redo procedures in 21 (91%) cases: 20 (87%) patients had both redo IPAAs for septic complications. After a median follow-up of 39 months (interquartile range, 18.5-95.5 months), pouch failure occurred in 8 (30%) cases (7 cases due to sepsis, of whom 3 never had their stoma closed, and 1 case due to poor function); all patients who experienced pouch failure underwent the second redo procedure due to septic complications. Overall pouch survival at 3 years was 76%: 62.5% in patients with a final diagnosis of Crohn's disease versus 82.5% in patients with ulcerative/indeterminate colitis ( p = 0.09). Overall quality-of-life score (0-1) was 0.6 (0.5-0.8). Quality of life and functional outcomes were comparable between first and second redo procedures, except incontinence, which was higher in second redo procedures.

LIMITATIONS

Single-center retrospective review.

CONCLUSIONS

A second pouch salvage procedure may be offered with acceptable outcomes to selected patients with high motivation to keep intestinal continuity. See Video Abstract .

Routine diversion following delayed IPAA construction does not reduce the incidence of pouch-related sepsis or failure in patients with ulcerative colitis

AIM

The aim of this study was to compare modified 2-stage and 3-stage IPAA construction techniques to evaluate the effect of diverting loop ileostomy following completion proctectomy and IPAA for ulcerative colitis. In addition, our overall institutional experience was reviewed to describe long-term outcomes and changes in staging trends over time.

METHODS

Our institutional database was searched to identify all cases of IPAA for ulcerative colitis between 1981 and 2018. Patient, pouch and outcome characteristics were abstracted. Primary study outcomes were the incidence of primary pouch failure and pouch-related sepsis. Failure was evaluated by Kaplan-Meier estimates of survival over time. The adjusted effect of pouch stage was evaluated using multivariable Cox and logistic regression models. Exploratory analysis evaluated the effect of stage on failure in the pouch related sepsis subgroup.

RESULTS

A total of 2105 patients underwent primary IPAA over the study period. The 5, 10 and 20-year pouch survival probabilities were 95.2%, 92.7% and 86.6%. The incidence of pouch related sepsis was 12.3%. Adjusted analysis demonstrated no difference in pouch failure (HR = 0.64: 95% 0.39-1.07, p = 0.09) or post-operative sepsis (aOR = 0.79: 95% CI 0.53-1.17, p = 0.24) by stage of construction. Among patients experiencing pouch sepsis, there was no difference in Kaplan-Meier estimates of pouch survival by stage (p = 0.90).

CONCLUSIONS

Pouch related sepsis and IPAA failure did not differ between modified 2-stage and 3-stage construction techniques. Among the sub-group of patients experiencing pouch related sepsis, there was no difference in failure between groups. The results suggest diverting ileostomy may be safely avoided following delayed pouch reconstruction in appropriately selected patients.

Transabdominal IPAA Revision: Does Indication Dictate Outcome?

BACKGROUND

Following IPAA failure, select patients are eligible for IPAA revision. Presently, there is limited evidence describing long-term revision outcomes and predictors of revision failure. This represents an important knowledge gap when selecting and counseling patients.

OBJECTIVE

This study aimed to define long-term IPAA survival outcomes after transabdominal IPAA revision and identify preoperative clinical factors associated with revision failure.

DESIGN

This was a retrospective cohort study.

SETTINGS

This study was conducted at a tertiary referral center.

PATIENTS

This study included all patients who underwent revisional IPAA surgery between 1982 and 2017 for pouch failure.

INTERVENTION

Transabdominal IPAA revision was included.

MAIN OUTCOME MEASURES

The primary outcome was pouch failure, defined as pouch excision or permanent pouch diversion, after IPAA revision.

RESULTS

A total of 159 patients (64.2% women) were included with a median age of 36 years (interquartile range, 28.5-46.5) at revision. Eighty percent of patients had a primary diagnosis of ulcerative colitis. The most common indication for revision was leak/pelvic sepsis, representing 41% of the cohort, followed by pouch-vaginal fistula (22.2%), mechanical factors (20.4%), and poor pouch function (14.6%). During the study period, 56 patients (35.2%) experienced pouch failure. The 3-year pouch survival probability was 82.3% (95% CI, 75.5%-87.5%), 5-year pouch survival probability was 77.2% (95% CI, 69.8%-83.0%), and 10-year pouch survival probability was 70.6% (95% CI, 62.6%-77.2%). Compared to mechanical factors, pouch failure was significantly associated with pelvic sepsis (HR, 4.25; 95% CI, 1.50-12.0) and pouch-vaginal fistula (HR, 4.37; 95% CI, 1.47-12.99). No significant association was found between revision failure and previous revision, redo ileoanal anastomosis, or new pouch construction.

LIMITATIONS

This study is limited by its retrospective design.

CONCLUSIONS

Revisional IPAA can be undertaken with favorable long-term outcomes at high-volume centers. Consideration should be given to indication for revision when counseling patients regarding the risk of failure. Further research on risk stratifying patients before revision is required.

ECCO Guidelines on Therapeutics in Ulcerative Colitis: Surgical Treatment

This is the second of a series of two articles reporting the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of adult patients with ulcerative colitis [UC]. The first article is focused on medical management, and the present article addresses medical treatment of acute severe ulcerative colitis [ASUC] and surgical management of medically refractory UC patients, including preoperative optimisation, surgical strategies, and technical issues. The article provides advice for a variety of common clinical and surgical conditions. Together, the articles represent an update of the evidence-based recommendations of the ECCO for UC.

Staging Pouch Surgery in Ulcerative Colitis in the Biological Era

Restorative proctocolectomy, or ileal pouch anal anastomosis, is considered the standard treatment for intractable ulcerative colitis. When the pelvic pouch was first introduced in 1978, a two-stage procedure with proctocolectomy, construction of the pelvic pouch, and a diverting loop with subsequent closure were suggested. Over the decades that the pelvic pouch has been around, some principal technical issues have been addressed to improve the method. In more recent days the laparoscopic approach has been additionally introduced. During the same time-period the medical arsenal has developed far more with the increasing use of immune modulators and the introduction of biologicals. Staging of restorative proctocolectomy with a pelvic pouch refers to how many sessions, or stages, the procedure should be divided into. The main goal with restorative proctocolectomy is a safe operation with optimal short- and long-term function. In this paper we aim to review the present knowledge and views on staging of the pouch procedure in ulcerative colitis, especially with consideration to the treatment with biologicals.

Ileal Pouch-anal Anastomosis Complications and Pouch Failure: A systematic review and meta-analysis

Objective

This systematic review aims to assess the incidence of pouch failure and the correlation between ileal pouch-anal anastomosis (IPAA)-related complications and pouch failure.

Background

Previous studies demonstrated wide variation in postoperative complication rates following IPAA.

Methods

A systematic review was performed by searching the MEDLINE, EMBASE, and Cochrane Library databases for studies reporting on pouch failure published from January 1, 2010, to May 6, 2020. A meta-analysis was performed using a random-effects model, and the relationship between pouch-related complications and pouch failure was assessed using Spearman's correlations.

Results

Thirty studies comprising 22,978 patients were included. Included studies contained heterogenic patient populations, different procedural stages, varying definitions for IPAA-related complications, and different follow-up periods. The pooled pouch failure rate was 7.7% (95% confidence intervals: 5.56-10.59) and 10.3% (95% confidence intervals: 7.24-14.30) for studies with a median follow-up of ≥5 and ≥10 years, respectively. Observed IPAA-related complications were anastomotic leakage (1-17%), pelvic sepsis (2-18%), fistula (1-30%), stricture (1-34%), pouchitis (11-61%), and Crohn's disease of the pouch (0-18%). Pelvic sepsis (r = 0.51, P < 0.05) and fistula (r = 0.63, P < 0.01) were correlated with pouch failure. A sensitivity analysis including studies with a median follow-up of ≥5 years indicated that only fistula was significantly correlated with pouch failure (r = 0.77, P < 0.01).

Conclusions

The single long-term determinant of pouch failure was pouch fistula, which is a manifestation of a chronic leak. Therefore, all effort should be taken to prevent an acute leak from becoming a chronic leak by early diagnosis and proactive management of the leak.

Mini abstract

This systematic review aims to assess the incidence of pouch failure and the correlation between IPAA-related complications and pouch failure. Long-term pouch failure was correlated with fistula, suggesting that early septic complications may result in fistula formation during long-term follow-up, leading to an increased risk of pouch failure.

Short-term and Long-term Outcomes Following Pelvic Pouch Excision: The Mount Sinai Hospital Experience

BACKGROUND

Few studies have reported surgical outcomes following pouch excision and fewer have described the long-term sequelae. Given the debate regarding optimal surgical management following pouch failure, an accurate estimation of the morbidity associated with this procedure addresses a critical knowledge gap.

OBJECTIVE

The objective of this study was to review our institutional experience with pouch excision with a focus on indications, short-term outcomes, and long-term reintervention rates.

DESIGN

This was a retrospective cohort study.

SETTING

This study was conducted at Mount Sinai Hospital, Toronto, Ontario Canada.

PARTICIPANTS

Adult patients registered in the prospectively maintained IBD database with a diagnosis of pelvic pouch failure between 1991 and 2018 were selected.

INTERVENTION

The patients had undergone pelvic pouch excision was measured.

MAIN OUTCOMES AND MEASURES

Indications for excision, incidence of short-term and long-term complications, and long-term surgical reintervention were the primary outcomes. In addition, multivariable logistic regression models were fitted to identify predictors of chronic perineal wound complications and the effect of preoperative diversion. The positive predictive value of a clinical suspicion of Crohn's disease of the pouch was also evaluated.

RESULTS

One hundred forty cases were identified. Fifty-nine percent of patients experienced short-term complications and 49.3% experienced delayed morbidity. Overall, one-third of patients required long-term reoperation related to perineal wound, stoma, and hernia complications. On multivariable regression, immunosuppression was associated with increased odds of perineal wound complications, and preoperative diversion was not associated with perineal wound healing. Crohn's disease was suspected in 24 patients preoperatively but confirmed on histopathology in only 6 patients.

LIMITATIONS

This is a retrospective chart review of a single institution's experience, whereby complication rates may be underestimates of the true event rates.

CONCLUSIONS

Pouch excision is associated with high postoperative morbidity and long-term reintervention due to nonhealing perineal wounds, stoma complications, and hernias. Further study is required to clarify risk reduction strategies to limit perineal wound complications and the appropriate selection of patients for diversion alone vs pouch excision in IPAA failure.

Fertility Impact of Initial Operation Type for Female Ulcerative Colitis Patients

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is the mainstay of surgical treatment for patients with ulcerative colitis (UC) but is associated with an increased risk of infertility. We developed a simulation model examining the impact of initial surgical procedure on quality-adjusted life-years (QALYs) and fertility end points.

METHODS

A patient-level state transition model was used to analyze outcomes by surgical approach strategy for females of childbearing age. Initial surgical options included IPAA, rectal-sparing colectomy with end ileostomy (RCEI), and ileorectal anastomosis (IRA). The primary outcome examined was QALYs, whereas secondary outcomes included UC and fertility-associated end points.

RESULTS

IPAA resulted in higher QALYs for patients aged 20-30 years, as compared with RCEI. For patients aged 35 years, RCEI resulted in higher QALYs (7.54 RCEI vs 7.53 IPAA) and was associated with a 28% higher rate of childbirth, a 14-month decrease in time to childbirth, and a 77% reduction in in vitro fertilization utilization. When accounting for the decreased infertility risk associated with laparoscopic IPAA, IPAA resulted in higher QALYs (7.57) even for patients aged 35 years.

CONCLUSIONS

Despite an increased risk of infertility, our model results suggest that IPAA may be the optimal surgical strategy for female UC patients aged 20-30 years who desire children. For patients aged 35 years, RCEI should additionally be considered, as QALYs for RCEI and IPAA were similar. These quantitative data can be used by patients and providers to help develop an individualized approach to surgical management choice.

Endo-sponge Assisted Early Surgical Closure of Ileal Pouch-anal Anastomotic Leakage Preserves Long-term Function: A Cohort Study

BACKGROUND AND AIMS

Endo-sponge [Braun Medical] assisted early surgical closure [ESC] is an effective treatment to control pelvic sepsis after ileal pouch-anal anastomosis [IPAA] leakage, and became standard treatment in our centre from 2010 onwards. The aim of this cohort study was to assess the long-term pouch function of ulcerative colitis [UC] patients treated with ESC or conventional management [CM] for anastomotic leakage after IPAA.

METHODS

Consecutive patients who underwent an IPAA for UC between 2002 and 2017 were included. Patients treated with ESC [2010-2017] or CM [2002-2009] for anastomotic leakage were compared with control patients without anastomotic leakage of the corresponding time period. Main endpoints were long-term pouch function on a 3-point scale and pouch failure, as measured with the validated pouch dysfunction score questionnaire.

RESULTS

Some 280 of 334 patients [84%] returned the pouch dysfunction questionnaire, of whom 18 were treated with ESC and 22 with CM for anastomotic leakage. Control cohorts included 133 [2010-2017] and 107 patients [2002-2009]. Between ESC-treated patients and control patients, pouch function [p = 0.647] and pouch failure rates [0/18 versus 5/133, p >0.99] were similar. CM resulted in worse pouch function [p = 0.016] and a higher pouch failure rate [5/22 versus 5/107, p = 0.013] compared with control patients.

CONCLUSIONS

ESC, in contrast to CM, for IPAA leakage in UC patients is associated with preservation of pouch function and preclusion of pouch failure, probably due to early and effective treatment of pelvic sepsis.

Morbidity related to diverting ileostomy after restorative proctocolectomy in patients with ulcerative colitis

AIM

Restorative proctocolectomy with ileal pouch-anal anastomosis is considered by many surgeons to be the standard procedure for surgical management of ulcerative colitis. There is controversy about whether or not a covering ileostomy should be constructed. The aim of this study was to evaluate the outcomes and morbidity for patients with ulcerative colitis who underwent restorative proctocolectomy with or without a diverting ileostomy.

METHOD

This is a retrospective study of a consecutive series of 510 patients with ulcerative colitis who were operated on in Helsinki University Hospital between January 2005 and June 2016. A diverting ileostomy was performed in 119 patients (the stoma group) compared with 391 patients with no stoma.

RESULTS

Dehydration and intestinal obstruction occurred more often in the stoma group (P < 0.0001). Clinical anastomotic leakage was more common among patients without an ileostomy (6.6% vs 1.7%, P = 0.04). However, the need for re-laparotomy because of any early complication did not differ between the groups (P = 0.58). Within 3 months, 50 patients with ileostomy (42.0%) and 51 patients without (13.0%) were readmitted (P < 0.0001). In total, 35 patients (29.3%) had a complication relating to ileostomy closure and four of them required surgery. There was no difference in the rate of fistulas, pouchitis or pouch failure between the groups.

CONCLUSION

Our study shows that a diverting ileostomy is associated with considerable morbidity but it does not seem to prevent later failure of the pouch. We suggest that a diverting ileostomy should only be constructed for high-risk patients.

Anastomotic Sinus That Developed From Leakage After a Rectal Cancer Resection: Should We Wait for Closure of the Stoma Until the Complete Resolution of the Sinus?

Purpose

The aims of this study were to identify the clinical characteristics of an anastomotic sinus and to assess the validity of delaying stoma closure in patients until the complete resolution of an anastomotic sinus.

Methods

The subject patients are those who had undergone a resection of rectal cancer from 2011 to 2017, who had a diversion ileostomy protectively or therapeutically and who developed a sinus as a sequelae of anastomotic leakage. The primary outcomes that were measured were the incidence, management and outcomes of an anastomotic sinus.

Results

Of the 876 patients who had undergone a low anterior resection, 14 (1.6%) were found to have had an anastomotic sinus on sigmoidoscopy or a gastrografin enema before their ileostomy closure. In the 14 patients with a sinus, 7 underwent ileostomy closure as scheduled, with a mean closure time of 4.1 months. The remaining 7 patients underwent ileostomy repair, but it was delayed until after the follow-up for the widening of the sinus opening by using digital dilation, with a mean closure time of 6.9 months. Four of those remaining seven patients underwent stoma closure even though their sinus condition had not yet been completely resolved. No pelvic septic complications occurred after closure in any of the 14 patients with an anastomotic sinus, but 2 of the 14 needed a rediversion due to a severe anastomotic stricture.

Conclusion

Patients with an anastomotic sinus who had been carefully selected underwent successful ileostomy closure without delay.

Management of early pouch-related septic complications in ulcerative colitis: a systematic review

AIM

It is well established that ileo-anal pouch-related septic complications (PRSC) increase the risk of pouch failure. There are a number of publications that describe the management of early PRSC in ulcerative colitis (UC) in small series. This article aims to systematically review and summarize the relevant current data on this subject and provide an algorithm for the management of early PRSC.

METHOD

A systematic review was undertaken in accordance with PRISMA guidelines. Studies published between 2000 and 2017 describing the clinical management of PRSC in patients with UC within 30 days of primary ileo-anal pouch surgery were included. A qualitative analysis was undertaken due to the heterogeneity and quality of studies included.

RESULTS

A total of 1157 abstracts and 266 full text articles were screened. Twelve studies were included for analysis involving a total of 207 patients. The studies described a range of techniques including image-guided, endoscopic, surgical and endocavitational vacuum methods. Based on the evidence from these studies, an algorithm was created to guide the management of early PRSC.

CONCLUSION

The results of this review suggest that although successful salvage of early PRSC is improving there is little information available relating to methods of salvage and outcomes. Novel techniques may offer an increased chance of salvage but comparative studies with longer follow-up are required.

The prevalence of chronic peri-pouch sepsis in patients treated for antibiotic-dependent or refractory primary idiopathic pouchitis

AIM

Chronic peri-pouch sepsis (CPPS) may be mistaken for antibiotic-dependent or refractory primary idiopathic pouchitis (ADRP), but requires different treatment such as drainage. The study aimed to identify the prevalence of CPPS in patients thought to have ADRP. The secondary aims were to identify any specific features on pouchoscopy suggesting CPPS and to determine the results of treatment for CPPS.

METHOD

The records of patients who had been treated for ADRP between March 2006 and June 2015 were reviewed retrospectively. Only those with endoscopic evidence of pouch inflammation who had also undergone MRI of the pelvis were included. The findings on pouchoscopy and the outcome of treatment were determined.

RESULTS

Sixty-eight patients (43 men, 63%) were identified with apparent ADRP between March 2006 and June 2015. MRI of the pelvis showed CPPS in 26 (38%). In those with CPPS, the inflammation was more often located in the upper pouch alone (15%) compared with patients without CPPS (0%) (P = 0.0184). Examination under anaesthesia was performed in 13 of those with CPPS. In five a collection was identified and drained; symptoms improved in only one (4%). Eighteen patients (69%) remained on antibiotics and seven (27%) had a defunctioning stoma or underwent pouch excision.

CONCLUSION

In patients thought to have ADRP, 38% had CPPS on MRI. There was no clinically relevant specific feature on pouchoscopy suggestive of CPPS. The possibility of CPPS should be considered early in patients with apparent ADRP and pelvic MRI performed. This might lead to earlier detection of CPPS and appropriate treatment.

Early postoperative complications have long-term impact on quality of life after restorative proctocolectomy

INTRODUCTION

Early postoperative complications graded according to the Clavien-Dindo classification system have not previously been correlated with long-term quality of life outcomes in patients who have had restorative proctocolectomy with ileal pouch-anal anastomosis. This study aimed to assess the severity of early postoperative complications and compared these in terms of the long-term quality of life after restorative proctocolectomy in a population-based cohort of patients (operated on from 1984 to 2013). It was hypothesized that those who experienced grade 3 or 4 Clavien-Dindo complications would have worse quality of life at follow-up.

METHODS

This population-based study used a combination of a retrospective note review and a cross-sectional questionnaire. All patients with a restorative proctocolectomy performed in 1984-2013 in the Canterbury region were recruited using multiple sources. Early (≤30 days) and late (>30 days) complication rates were obtained via patient records. Early postoperative complications were graded according to the Clavien-Dindo classification. Quality of life was measured using the inflammatory bowel disease questionnaire.

RESULTS

One hundred and thirty-six people were identified with a median follow-up of 12 years. Data were available for 121 patients for early complications and 112 for late complications. Eighty-one eligible participants had their quality of life assessed (86% response rate). Early complications occurred in 26% and 76% had late complications. Those who had Clavien-Dindo grade 3 or 4 early complications had lower quality of life scores (P = 0.001) as did females (P = 0.004) and those with a stricture (P = 0.031).

CONCLUSION

This population-based study with long-term follow-up demonstrates that Clavien-Dindo grade 3 and 4 postoperative complications are important in determining quality of life in the long term. The reduction in these complications should be a focus of patient management, as it should improve long-term quality of life.

Severity of inflammation as a risk factor for ileo-anal anastomotic leak after a pouch procedure in ulcerative colitis

PURPOSE

The pelvic pouch procedure (PPP) carries significant post-operative complication risks including a 4-14 % risk of ileo-anal anastomotic (IAA) leak [1-4]. The aim of this study is to evaluate the severity of disease at the distal resection margin as an independent risk factor for an IAA leak following the PPP for patients with ulcerative colitis (UC).

METHODS

A retrospective matched case-control study was undertaken. The distal margin of each subject's specimen was reviewed by a blinded pathologist and the degree of inflammation was scored using a modified histological activity index (mHAI)--a 0 to 5 graded scale with HAI of 5 representing ulcerations >25 % the depth of bowel wall.

RESULTS

Forty-nine patients with perioperative IAA leaks (mean 11 days ±0.92) were identified and matched for gender, age and year of surgery. The case cohort had 33 males (67 %) of mean age at time of surgery of 36.3 years (±1.42). The severity of distal inflammation did not increase the risk of IAA leak. The presence of a diverting ileostomy was associated with a decreased incidence of an IAA leak (p = 0.01).

CONCLUSION

Studies with greater power will be required to evaluate the association (if any) between histological severity of UC at the distal margin of a PPP procedure and IAA leak rate. This risk factor could influence preoperative management and post-operative outcome in patients requiring the PPP.

Male issues of the ileal pouch

: Restorative proctocolectomy with ileal pouch-anal anastomosis is the standard surgical treatment modality for patients with ulcerative colitis who require colectomy. There are special issues related to male gender. We performed systemic literature review on the topic, incorporating the experience in our specialized Center for Ileal Pouch Disorders, and provide recommendations for the identification and management for the gender-specific issues in male patients with ileal pouches. Chronic pouchitis, particularly ischemic pouchitis, anastomotic leak, and presacral sinus are more common in male patients than their female counterparts. Sexual dysfunction can occur after pouch surgery, particularly in those with pouch failure. Diagnosis and management of benign and malignant prostate diseases can be challenging due to the altered pelvic anatomy from the surgery. Digital rectal examination for prostate cancer screening is not reliable. Transpouch biopsy of prostate may lead to pouch fistula or abscess. Pelvic radiation therapy may have an adverse impact on the pouch function. In conclusion, sexual dysfunction and enlarged prostate can occur in patients with the ileal pouch. The measurement of serum prostate-specific antigen is a preferred method for the screening of prostate cancer. If biopsy of the prostate is needed, the perineal route is recommended. The risk for pouch dysfunction and the benefit for oncologic survival of pelvic radiation for prostate cancer should be carefully balanced.

Restorative proctocolectomy with a handsewn IPAA: S-pouch or J-pouch?

BACKGROUND

The efferent limb on the S-pouch fits well into the anal canal while the body of the pouch lies on the levators. In contrast, the blunt end of a J-pouch may be distorted as it is forced into the muscular tube of the stripped anus.

OBJECTIVE

The aim of this study is to compare the clinical outcomes and quality of life between patients with S- and J-pouches with a handsewn IPAA.

DESIGN

This study was retrospective.

SETTING

This study was conducted at a high-volume tertiary referral center.

PATIENTS

Patients undergoing a primary handsewn IPAA from 1983 to 2012 were identified.

MAIN OUTCOMES MEASURES

Demographics, operative details, functional outcomes, and quality of life were abstracted.

RESULTS

A total of 502 patients, including 169 patients with an S-pouch (33.7%) and 333 patients with J-pouch (66.3%), met our inclusion criteria; 55.8% (n = 280) were men. Mean age at pouch construction was 37.8 ± 12.5 years. Patients with an S-pouch were younger (p = 0.004) and had a higher BMI (p = 0.035) at pouch surgery. There was no significant difference between patients with S- or J-pouches in other demographics. The frequencies of short-term complications in the 2 groups were similar (p > 0.05), but pouch fistula or sinus (p = 0.047), pelvic sepsis (p = 0.044), postoperative partial small-bowel obstruction (p = 0.003), or postoperative pouch-related hospitalization (p = 0.021) occurred in fewer patients with an S-pouch. At a median follow-up of 12.2 (range, 4.3-20.1) years, patients with an S-pouch were found to have fewer bowel movements (p < 0.001), less frequent pad use (p = 0.001), and a lower fecal incontinence severity index score (p = 0.015). The pouch failed in 62 patients (12.4%), but neither univariate nor multivariate analysis showed a significant association with pouch configuration.

LIMITATIONS

The use of data from a single tertiary referral center was a limitation of this study.

CONCLUSION

We recommend using an S-pouch when constructing an IPAA with a handsewn technique.

NSAID use and anastomotic leaks following elective colorectal surgery: a matched case-control study

INTRODUCTION

Non-steroidal anti-inflammatory drugs (NSAIDs) decrease postoperative pain and opioid consumption. The objective of the study was to determine if postoperative NSAIDs were associated with anastomotic leaks following elective colorectal surgery.

MATERIALS AND METHODS

We used a matched nested case-control study design. Using a prospectively collected database, we identified all patients having elective colorectal surgery between January 2001 and June 2012. Cases and matched controls were identified based on the occurrence of a postoperative anastomotic leak. The primary and secondary exposure variables were, respectively, use of any NSAID and use of ketorolac specifically. Conditional logistic regression was used to determine the unadjusted and adjusted odds ratio.

RESULTS

A total of 262 patients were included (65.6 % inflammatory bowel disease, 34.4 % cancer). Use of any NSAID was associated with a non-significant increase in anastomotic leaks (odds ratio (OR) 1.81, 95 % confidence interval (CI) 0.98-3.37, p = 0.06). Use of ketorolac was associated with a significant increase in anastomotic leaks (OR 2.09, 95 % CI 1.12-3.89, p = 0.021). There was no significant association between anastomotic leaks and cumulative NSAID dose.

CONCLUSION

These data suggest that there may be an association between NSAIDs and risk of anastomotic leaks after colorectal surgery. Further research is needed to better elucidate this relationship to clarify the implications for patients.

Comparable pouch retention rate between pediatric and adult patients after restorative proctocolectomy and ileal pouches

BACKGROUND & AIMS

We compared long-term outcomes between adult and pediatric patients with inflammatory bowel disease (IBD) who underwent restorative proctocolectomy with ileal pouch-anal anastomosis.

METHODS

We performed a retrospective study that analyzed data from consecutive patients with ileal pouches who presented to the subspecialty Pouch Center at the Cleveland Clinic from 2002-2011. Pouch outcomes of 104 pediatric patients (having pouch surgery at age <18 years; 53 male) were compared with those of 1135 adults (having pouch surgery at an age 18 years or older; 632 male).

RESULTS

Pediatric patients had a shorter duration from time of IBD diagnosis to colectomy than adult patients. Fewer pediatric than adult patients had a history of smoking, concomitant extraintestinal manifestations, or dysplasia as the indication for colectomy. However, pediatric patients had higher rates of pouch procedure-related complications, postoperative pouch-associated hospitalization, and postoperative use of anti-tumor necrosis factor (TNF) agents. In multivariate analysis, risk factors for pouch failure included preoperative use of anti-TNF agents (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.05-3.13; P = .032), postoperative use of anti-TNF agents (HR, 2.07; 95% CI, 1.31-3.27; P = .002), Crohn's disease of the pouch (HR, 2.21; 95% CI, 1.28-3.82; P = .005), pouch procedure-related complications (HR, 2.68; 95% CI, 1.55-4.64; P < .001), and postoperative pouch-associated hospitalization (HR, 25.20; 95% CI, 14.44-43.97; P < .001). Being a pediatric patient was not significantly associated with pouch failure in univariate or multivariate analyses (HR, 0.6; 95% CI, 0.32-1.16; P = .13).

CONCLUSIONS

On the basis of an analysis of patients with IBD who underwent restorative proctocolectomy and presented at a subspecialized Pouch Center, patients who had the surgery at a pediatric age tend to have a higher incidence of postoperative pouch complications than adults. However, long-term rates of pouch retention were comparable.

Excessive weight gain is associated with an increased risk for pouch failure in patients with restorative proctocolectomy

BACKGROUND

The aim was to evaluate the impact of weight gain on pouch outcomes after ileostomy closure.

METHODS

Consecutive inflammatory bowel disease patients with ileal pouches followed up at our subspecialty Pouch Center from 2002 to 2011 were studied. The association of excessive weight gain (defined as a 15% increase the index weight) with pouch outcomes were evaluated using univariate and multivariate analyses.

RESULTS

A total of 846 patients met inclusion criteria, with 470 (55.6%) being men. The mean age at the diagnosis of inflammatory bowel disease and at pouch surgery was 27.2 ± 11.9 years and 37.8 ± 12.8 years, respectively. Patients with weight gain more likely had mechanical or surgical complications of the pouch (18.4% versus 12.3%, P = 0.049), Crohn's disease of the pouch (30.6% versus 18.5%, P = 0.001), Pouch Center visits (2.0 [1.0-4.0] versus 2.0 [1.0-3.0], P = 0.008), and postoperative pouch-related hospitalization (21.1% versus 10.6%, P < 0.001). After a median follow-up of 9.0 (interquartile range = 4.0-14.0) years, 68 patients (8.0%) developed pouch failure. In the multivariate analysis, excessive weight gain was an independent risk factor for pouch failure with a hazard ratio of 1.69 (95% confidence interval = 1.01-2.84, P = 0.048) after adjusting for preoperative or postoperative use of anti-tumor necrosis factor biologics, postoperative use of immunosuppressants, Crohn's disease of the pouch, mechanical or surgical complications of the pouch, and postoperative pouch-associated hospitalization.

CONCLUSIONS

Excessive weight gain after closure of the ileostomy is associated with worse pouch outcomes in patients with inflammatory bowel disease. Appropriate weight control may help improve pouch retention.

Considerations and complications in patients undergoing ileal pouch anal anastomosis

Total proctocolectomy with ileal pouch anal anastomosis (IPAA) preserves fecal continence as an alternative to permanent end ileostomy in select patients with ulcerative colitis and familial adenomatous polyposis. The procedure is technically demanding, and surgical complications may arise. This article outlines both the early and late complications that can occur after IPAA, as well as the workup and management of these potentially morbid conditions.

The management of anastomotic pouch sinus after IPAA

BACKGROUND

Anastomotic sinus is a relatively uncommon complication after an IPAA. Disease course is poorly defined, and management can be challenging.

OBJECTIVE

The purpose of this study was to evaluate the frequency, management, and outcome of anastomotic pouch sinus.

DESIGN

This research is a retrospective cohort study from a prospectively collected database.

SETTING

The investigation took place in a high-volume specialized colorectal surgery department.

PATIENTS

Patients with an anastomotic sinus after pouch surgery from 1997 to 2009 were included.

MAIN OUTCOMES MEASURES

The primary outcomes measured were sinus healing and pouch failure.

RESULTS

Of 2286 patients who underwent an IPAA, 45 (2.0%) patients were identified with an anastomotic pouch sinus. There were 32 (71%) males, and the mean age was 40 (±13) years. The pouch sinus was initially managed by observation in 23 (51%) patients, drainage of the sinus in 9 (20%) patients, unroofing of the sinus tract in 8 (18%) patients, sinus closure in 3 (7%) patients, and a diverting ileostomy in 2 (4%) patients. In 28 patients (62%), subsequent treatment was necessary. Sinus healing was achieved in 27 (60%) patients, whereas 15 (33%) eventually developed pouch failure. Of the treatment modalities applied, a strategy with observation as initial treatment was the most successful with a healing rate of 65%. The healing rate was significantly lower in symptomatic patients in comparison with asymptomatic patients (30% vs 84%, p = 0.001). Pouch failure was also higher (45% vs 24%, p = 0.14). No other factors associated with healing rate or pouch failure were identified.

LIMITATIONS

This study was limited by its nonrandomized retrospective design.

CONCLUSION

Anastomotic pouch sinuses after pouch surgery are associated with a high rate of pouch failure. Symptomatic presentation is a significant predictor for low healing rates and is associated with a high risk of pouch failure. Observation and watchful monitoring is the initial treatment of choice when permitted by the patient's condition.

Pelvic sepsis after IPAA adversely affects function of the pouch and quality of life

BACKGROUND

Pelvic sepsis after IPAA predisposes to pouch failure. There are limited data on long-term pouch function for patients with pelvic sepsis.

OBJECTIVE

The aim of this study was to investigate functional outcomes and quality of life for patients undergoing IPAA who develop pelvic sepsis and preserve their pouch long-term.

DESIGN

This study is based on retrospective analysis of prospectively accrued data.

SETTINGS

This study was conducted at a single-center institution.

PATIENTS

All patients undergoing IPAA from 1983 to 2007 were included.

MAIN OUTCOME MEASURES

The primary outcomes measured were functional outcomes (urgency, incontinence, bowel movements) and quality-of-life (restrictions, energy, happiness) parameters.

RESULTS

Two hundred (6.2%) of 3234 patients developed pelvic septic complications within 3 months of IPAA. In the comparison of complications at the time of IPAA for the 2 groups, patients with pelvic sepsis had higher rates of postoperative hemorrhage (13.5% vs 3.7%, p < 0.001), anastomotic leak (35% vs 3.7%, p < 0.001), wound infection (14% vs 7.4%, p < 0.001), and fistula formation (37% vs 7.1%, p < 0.001). The overall median follow-up was 7 years. Pelvic sepsis was associated with greater pouch failure (19.5% vs 4%, p < 0.001). For patients with follow-up (pelvic sepsis = 144, nonpelvic sepsis = 2677) with a retained pouch, for whom we compared functional outcomes and quality of life, incontinence was worse (never/rare: 69.5% vs 77.8%, p = 0.03). Urgency scores were lower in pelvic sepsis but not statistically significant. The overall Cleveland Global Quality of Life score (and components) in the sepsis group were significantly worse than in the nonsepsis group (0.74 vs 0.79, p < 0.001). Patients who developed sepsis were also less likely to recommend IPAA to others than patients who did not develop pelvic sepsis.

LIMITATIONS

This study was limited by the retrospective analysis and the use of questionnaires.

CONCLUSIONS

Pelvic sepsis after IPAA leads to worse functional outcomes and quality of life even when it does not lead to pouch failure. This finding argues for careful attention to preoperative and intraoperative planning and strategies aimed at reducing this complication after IPAA.

Permanent ostomy after ileoanal pouch failure: pouch in situ or pouch excision?

BACKGROUND

The risks and benefits of pouch excision and end ileostomy creation when compared to the alternative option of a permanent diversion with the pouch left in situ when restoration of intestinal continuity is not pursued for patients who develop pouch failure after IPAA have not been well characterized.

OBJECTIVE

This study aimed to compare the early and long-term outcomes after permanent diversion with the pouch left in situ vs pouch excision with end ileostomy creation for pouch failure.

DESIGN

This study is a retrospective review of prospectively gathered data.

SETTINGS

This investigation was conducted at a tertiary center.

PATIENTS

Patients with pouch failure who underwent a permanent ileostomy with the pouch left in situ and those who underwent pouch excision were included in the study.

MAIN OUTCOME MEASURES

The primary outcomes measured were the perioperative outcomes and quality of life using the pouch and Short Form 12 questionnaires.

RESULTS

One hundred thirty-six patients with pouch failure underwent either pouch left in situ (n = 31) or pouch excision (n = 105). Age (p = 0.72), sex (p = 0.72), ASA score (p = 0.22), BMI (p = 0.83), disease duration (p = 0.74), time to surgery for pouch failure (p = 0.053), diagnosis at pouch failure (p = 0.18), and follow-up (p = 0.76) were similar. The predominant reason for pouch failure was septic complications in 15 (48.4%) patients in the pouch left in situ group and 39 (37.1%) patients in the pouch excision group (p = 0.3). Thirty-day complications, including prolonged ileus (p = 0.59), pelvic abscess (p = 1.0), wound infection (p = 1.0), and bowel obstruction (p = 1.0), were similar. At the most recent follow-up (median, 9.9 y), quality of life (p = 0.005) and health (p = 0.008), current energy level (p = 0.026), Cleveland Global Quality of Life score (p = 0.005), and Short Form 12 mental (p = 0.004) and physical (p = 0.014) component scales were significantly higher after pouch excision than after pouch left in situ. Urinary and sexual function was similar between the groups. Anal pain (n = 4) and seepage with pad use (n = 8) were the predominant concerns of the pouch left in situ group on long-term follow-up. None of the 18 patients with pouch in situ, for whom information relating to long-term pouch surveillance was available, developed dysplasia or cancer.

LIMITATIONS

This study was limited by its retrospective nature.

CONCLUSIONS

Although technically more challenging, pouch excision, rather than pouch left in situ, is the preferable option for patients who develop pouch failure and are not candidates for restoration of intestinal continuity. Because pouch left in situ was not associated with neoplasia, this option is a reasonable intermediate or long-term alternative when pouch excision is not feasible or advisable.

Factors associated with ileoanal pouch failure in patients developing early or late pouch-related fistula

BACKGROUND

The natural history of a pouch-related fistula in terms of timing of its development and its impact on pouch survival is poorly defined.

OBJECTIVE

This study aimed to evaluate factors associated with the time of onset of ileoanal pouch-related fistulas and predictors of pouch failure after the development of fistulas.

DESIGN

This study is an evaluation of prospectively collected data from a cohort of patients with pouch-related fistulas.

SETTING

Patients were identified from a prospective ileoanal pouch database, with data recorded from 1983 to 2009.

PARTICIPANTS

Patients who participated had developed a fistula after ileoanal pouch surgery. Patients were classified according to the time of onset, origin, and target of pouch fistulas into "early" and late" groups.

MAIN OUTCOME MEASURE

Ileoanal pouch failure was the main outcome measure.

RESULTS

Three hundred six patients (158 early-onset, 148 late-onset) with 373 pouch-related fistulas were identified. The early-onset group had a higher mean body mass index (P = .013) and more patients in this group developed a postoperative leak (P < .001), whereas diagnosis revision to Crohn's disease was more frequent in the late-onset group (P = .018). Overall, pouch failure occurred in 89 (29%) patients. Major abdominal procedures were more common in the early-onset group (18 vs 6%). There was no difference in pouch failure between the early- and late-onset groups (P = .24). On multivariate analysis, a current Crohn's diagnosis (P < .001), major fistula (P = .022), history of colectomy before ileoanal pouch (P = .005), handsewn anastomosis (P = .008), anastomotic leak (P = .012), and body mass index over 30 (P = .018) were independent risk factors for failure. No individual risk factor for failure was separately associated with either early or late fistula groups.

CONCLUSIONS

The timing and etiology of pouch fistula appear to be interrelated. There is a temporal association between procedure-related sepsis and early and delayed diagnosis of Crohn's disease and late fistula development. Cause of the fistula and associated factors rather than timing after IPAA is associated with long term pouch retention.

Complications following restorative proctocolectomy in children

BACKGROUND

Adverse outcomes following restorative proctocolectomy (RPC) in adults have been attributed to steroid exposure and use of hand-sutured anastomoses. This study analyses complications in children undergoing RPC.

METHODS

This study is a retrospective review of all children undergoing RPC in an English regional center over a 10-year period. The main outcome measure was defined as a complication within 30 days of surgery. Logistic regression analysis was used with possible explanatory variables (eg, steroid use, indication for surgery, weight and height z scores, hematologic indices, degree of blood loss, and use of laparoscopic surgery).

RESULTS

Sixty (33 female) patients underwent RPC at a median age of 13.5 years. Of these, 16 had an operative complication and 17 had a late complication. Only severe acute colitis with inability to induce remission as an indication for surgery was significant in predicting operative complications (odds ratio, 6.8 [95% confidence interval, 1.2-37]; P = .03).

CONCLUSIONS

Severe acute colitis resistant to medical therapy but not steroid use or hand-sutured anastomoses appears to be a risk factor for complication. This differs from the adult experience.
