Complications after ileal pouch-anal anastomosis in Korean patients with ulcerative colitis

Review of long-term complications and functional outcomes of ileoanal pouch procedures in patients with inflammatory bowel disease

BACKGROUND

In medically refractory Ulcerative Colitis (UC), proctocolectomy with ileoanal pouch procedure (IAPP) is the preferred continence-preserving surgical option. Functional outcomes post-surgery and long-term complication rates in the biologic era remain ambiguous. This review primarily aims to provide an update on these outcomes. Secondarily, risk factors associated with chronic pouchitis and pouch failure are explored.

METHODS

Two online databases (MEDLINE and EMBASE) were searched on 4 October 2022 for English studies from 2011-present relating to long-term outcomes of IAPP in inflammatory bowel disease (IBD) patients. Adult patients with 12 month follow-up were included. Studies focused on 30-day post-operative outcomes, non-IBD patients or studies including less than 30 patients were excluded.

RESULTS

Following screening and full-text review of 1094 studies, 49 were included. Median sample size was n = 282 (IQR: 116-519). Median incidences for chronic pouchitis and pouch failure were 17.1% (IQR: 12-23.6%) and 6.9% (IQR: 4.8-10.8%), respectively. Upon multivariate analysis, chronic pouchitis development was most significantly associated with pre-operative steroid use, pancolitis and extra-intestinal IBD manifestations, whilst pouch failure was most significantly associated with pre-operative diagnosis of Crohn's disease (compared to UC), peri-operative pelvic sepsis and anastomotic leak. Overall patient satisfaction was very high with four included studies reporting greater than 90% satisfaction rates.

CONCLUSION

Long-term complications for IAPP were common. However, despite this, patient satisfaction post-IAPP was high. Up-to-date knowledge of complication rates and their risk factors improves pre-operative counselling, management planning and patient outcomes.

Ileoanal pouch-related fistulae: A systematic review with meta-analysis on incidence, treatment options and outcomes

BACKGROUND

Ileoanal pouch related fistulae (PRF) are a complication of restorative proctocolectomy often requiring repeated surgical interventions and with a high risk of long-term recurrence and pouch failure.

AIMS

To assess the incidence of PRF and to report on the outcomes of available surgical treatments.

METHODS

A PRISMA-compliant systematic literature search for articles reporting on PRF in patients with inflammatory bowel diseases (IBD) or familial adenomatous polyposis (FAP) from 1985 to 2020.

RESULTS

34 studies comprising 770 patients with PRF after ileal-pouch anal anastomosis (IPAA) were included. Incidence of PRF was 1.5-12%. In IBD patients Crohn's Disease (CD) was responsible for one every four pouch-vaginal fistulae (PVF) (OR 24.7; p=0.001). The overall fistula recurrence was 49.4%; procedure-specific recurrence was: repeat IPAA (OR 42.1; GRADE +); transvaginal repair (OR 52.3; GRADE ++) and transanal ileal pouch advancement flap (OR 56.9; GRADE ++). The overall failure rate was 19%: pouch excision (OR 0.20; GRADE ++); persistence of diverting stoma (OR 0.13; GRADE +) and persistent fistula (OR 0.18; GRADE +).

CONCLUSION

PVFs are more frequent compared to other types of PRF and are often associated to CD; surgical treatment has a risk of 50% recurrence. Repeat IPAA is the best surgical approach with a 42.1% recurrence rate.

Treatment of pouchitis, Crohn's disease, cuffitis, and other inflammatory disorders of the pouch: consensus guidelines from the International Ileal Pouch Consortium

Pouchitis, Crohn's disease of the pouch, cuffitis, polyps, and extraintestinal manifestations of inflammatory bowel disease are common inflammatory disorders of the ileal pouch. Acute pouchitis is treated with oral antibiotics and chronic pouchitis often requires anti-inflammatory therapy, including the use of biologics. Aetiological factors for secondary pouchitis should be evaluated and managed accordingly. Crohn's disease of the pouch is usually treated with biologics and its stricturing and fistulising complications can be treated with endoscopy or surgery. The underlying cause of cuffitis determines treatment strategies. Endoscopic polypectomy is recommended for large, symptomatic inflammatory polyps and polyps in the cuff. The management principles of extraintestinal manifestations of inflammatory bowel disease in patients with pouches are similar to those in patients without pouches.

The Microbiome as a Therapy in Pouchitis and Ulcerative Colitis

The gut microbiome has been implicated in a range of diseases and there is a rapidly growing understanding of this ecosystem's importance in inflammatory bowel disease. We are yet to identify a single microbe that causes either ulcerative colitis (UC) or pouchitis, however, reduced microbiome diversity is increasingly recognised in active UC. Manipulating the gut microbiome through dietary interventions, prebiotic and probiotic compounds and faecal microbiota transplantation may expand the therapeutic landscape in UC. Specific diets, such as the Mediterranean diet or diet rich in omega-3 fatty acids, may reduce intestinal inflammation or potentially reduce the risk of incident UC. This review summarises our knowledge of gut microbiome therapies in UC and pouchitis.

Systematic review on the management of ileoanal pouch-vaginal fistulas after restorative proctocolectomy in the treatment of ulcerative colitis

AIM

Ileoanal pouch-vaginal fistula (PVF) is a relatively common complication of restorative proctocolectomy with ileal pouch-anal anastomosis. There are several operative approaches in the management of PVF. There is currently no consensus as to which approach is the most effective or which should be attempted first.

METHOD

A systematic review was undertaken following a publicly available protocol registered with PROSPERO (CRD42019133750) in accordance with PRISMA guidelines. Online searches of databases MEDLINE and Embase, Cochrane Library, ClinicalTrials.gov, EU Clinical Trials and ISRCTN registry were performed.

RESULTS

Twenty-seven articles met the criteria for inclusion in the study: 13 retrospective cohort studies, two prospective cohort studies, eight case series, three case reports and a case-control study. A narrative synthesis was performed due to heterogeneity between included articles. Our study included 577 PVFs, and the incidence rate was 2.1%-17.1%. Both local and abdominal approaches were used in the management of PVF. The overall success of local and abdominal procedures was 44.9% and 60.2% respectively. ROBINS-I assessment revealed a critical risk of bias. GRADE assessment indicated a very low certainty in effect size and evidence quality.

CONCLUSION

Local interventions and abdominal approaches have a high failure rate. The results of this review will aid the counselling of patients with this condition. Furthermore, we provide an algorithm for discussion on the management of PVF based on experience at our local centre. The studies available on the management of PVF are low quality; a large prospective registry and Delphi consensus are required to further this area of research.

A systematic review and meta-analysis of outcomes after elective surgery for ulcerative colitis

AIM

Approximately 20%-30% of patients with ulcerative colitis (UC) will undergo surgery during their disease course, the vast majority being elective due to chronic refractory disease. The risks of elective surgery are reported variably. The aim of this systematic review and meta-analysis is to summarize the outcomes after elective surgery for UC.

METHODS

A systematic review was conducted that analysed studies reporting outcomes for elective surgery in the modern era (>2002). It was prospectively registered on the PROSPERO database (ref: CRD42018115513). Searches were performed of Embase and MEDLINE on 15 January 2019. Outcomes were split by operation performed. Primary outcome was quality of life; secondary outcomes were early, late and functional outcomes after surgery. Outcomes reported in five or more studies underwent a meta-analysis of incidence using random effects. Heterogeneity is reported with I² , and publication bias was assessed using Doi plots and the Luis Furuya-Kanamori index.

RESULTS

A total of 34 studies were included (11 774 patients). Quality of life was reported in 12 studies, with variable and contrasting results. Thirteen outcomes (eight early surgical complications, five functional outcomes) were included in the formal meta-analysis, all of which were outcomes for ileal pouch-anal anastomosis (IPAA). A further 71 outcomes were reported (50 IPAA, 21 end ileostomy). Only 14 of 84 outcomes received formal definitions, with high inter-study variation of definitions.

CONCLUSION

Outcomes after elective surgery for UC are variably defined. This systematic review and meta-analysis highlights the range of reported incidences and provides practical information that facilitates shared decision making in clinical practice.

Short-term Outcomes of Elective 2-Stage Restorative Proctocolectomy for Ulcerative Colitis in Korea: Does Laparoscopy Have Benefits?

Purpose

This study aimed to compare the short-term outcomes of the open and laparoscopic approaches to 2-stage restorative proctocolectomy (RPC) for Korean patients with ulcerative colitis (UC).

Methods

We retrospectively analyzed the medical records of 73 patients with UC who underwent elective RPC between 2009 and 2016. Patient characteristics, operative details, and postoperative complications within 30 days were compared between the open and laparoscopic groups.

Results

There were 26 cases (36%) in the laparoscopic group, which had a lower mean body mass index (P = 0.025), faster mean time to recovery of bowel function (P = 0.004), less intraoperative blood loss (P = 0.004), and less pain on the first and seventh postoperative days (P = 0.029 and P = 0.027, respectively) compared to open group. There were no deaths, and the overall complication rate was 43.8%. There was no between-group difference in the overall complication rate; however, postoperative ileus was more frequent in the open group (27.7% vs. 7.7%, P = 0.043). Current smoking (odds ratio [OR], 44.4; P = 0.003) and open surgery (OR, 5.4; P = 0.014) were the independent risk factors for postoperative complications after RPC.

Conclusion

Laparoscopic RPC was associated with acceptable morbidity and faster recovery than the open approach. The laparoscopic approach is a feasible and safe option for surgical treatment for UC in selective cases.

A Systematic Review: The Management and Outcomes of Ileal Pouch Strictures

BACKGROUND

Restorative proctocolectomy with ileal pouch-anal anastomosis removes the diseased tissue in ulcerative colitis but also allows gastrointestinal continuity and stoma-free living. Pouch strictures are a complication with a reported incidence of 5-38%. The three areas where pouch strictures occur are in the pouch inlet, mid-pouch and pouch-anal anastomosis.

AIM

To undertake a systematic review of the literature and to identify management strategies available for pouch-anal, mid-pouch and pre-pouch ileal strictures and their outcomes.

METHODS

A computer-assisted search of the online bibliographic databases MEDLINE and EMBASE limited to 1966 to February 2016 was performed. Randomized controlled trials, cohort studies, observational studies and case reports were considered. Those where data could not be extracted were excluded.

RESULTS

Twenty-two articles were considered eligible. Pouch-anal strictures have been initially managed using predominately dilators which include bougie and Hegar dilators with various surgical procedures advocated when initial dilatation fails. Mid-pouch strictures are relatively unstudied with both medical, endoscopic and surgical management reported as successful. Pouch inlet strictures can be safely managed using a combined medical and endoscopic approach.

CONCLUSION

The limited evidence available suggests that pouch-anal strictures are best treated in a stepwise fashion with initial treatment to include digital or instrumental dilatation followed by surgical revision or resection. Management of mid-pouch strictures requires a combination of medical, endoscopic and surgical management. Pouch inlet strictures are best managed using a combined medical and endoscopic approach. Future studies should compare different treatment modalities on separate stricture locations to enable an evidenced-based treatment algorithm.

Early Outcome of Patient with Ulcerative Colitis who Received High Dose of Steroid and Underwent Two Staged Total Proctocolectomy

Background:

Ulcerative colitis (UC) is an idiopathic inflammatory disorder. Currently, the final treatment is colectomy. The aim of this study was to investigate the outcomes of proctocolectomy in patients that used a high dose of prednisolone.

Materials and Methods:

Seventy-five patients presenting for surgical management of histopathologically proven UC. All patients were offered total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA). Patients were divided into two groups: low dose of steroids (Group A) and high dose of steroid (Group B) consumers. Data from these patients after 2 years were reviewed and analyzed.

Results:

From total patients, 34 of them were male and 34 ones were female and seven patients underwent laparatomy. Overall incontinence rate was 8.8%; dysplasia was 22%, pouchitis was 18.9% while mortality was nil. The length of hospital stay was 6.76 days in Group A and 9.21 days in Group B (P = 0.399). Leakage was observed in nine of the patients after surgery (P = 0.589). Fecal incontinence between two groups was not statistically different (P = 0.063).

Conclusions:

Laparoscopic TPC-IPAA is feasible in patients needing surgical management of UC. Preoperative treatment with high-dose corticosteroids is associated with an increased risk of complications and reoperations.

Long-term quality of life associated with early surgical complications in patients with ulcerative colitis after ileal pouch-anal anastomosis: A single-center retrospective study

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is recommended for patients with ulcerative colitis (UC) in terms of surgical treatment. Measuring surgical complications of IPAA and long-term quality of life (QOL) are important to achieve an acceptable risk/benefit ratio for patients with UC.

MATERIALS AND METHODS

Patients with UC who underwent total proctocolectomy (TPC) with IPAA from February 2008 to July 2016 at our institute were included. Early surgical complications were defined as mechanical/infectious events within one month after IPAA. Assessment of QOL was performed using the Cleveland Global Quality of Life instrument (CGQL), with 50% improvement as a cut-off value. Demographic and clinical variables were compared with univariable analysis and step-wise logistic regression models were also performed.

RESULTS

A total of 58 eligible patients had a median follow-up time of 78.5 months [interquartile range (IQR), 34.4-92.8] from February2008 to March 2017, including 25 cases (43.1%) developed early surgical complications. Age at pouch surgery and excessive blood loss were risk factors associated with early surgical complications (p < 0.05). In multivariate analysis, older age at surgery [odds ratio (OR), 1.05; 95% confidence interval (CI), 1.01-1.1] and significant blood loss (≧400 ml) (OR, 4.31; 95% CI, 1.21-16.87) were contributing factors for developing early surgical complications. The CGQL score was significantly increased after IPAA (0.728 ± 0.151 vs. 0.429 ± 0.173, p < 0.001). Early surgical complications (OR, 5.55; 95%CI, 1.44-21.37), older age at surgery (OR, 1.06; 95% CI, 1.01-1.12) and use of immunomodulatory (OR, 17.50; 95% CI, 1.52-201.39) were associated with poor long-term QOL.

CONCLUSION

The study demonstrated that early surgical complications might contribute to develop a poor CGQL score, suggesting intentional control of risk factors associated with early surgical complications should be taken into consideration for patients with UC for pouch surgery.

Pouchitis after ileal pouch-anal anastomosis in ulcerative colitis: Diagnosis, management, risk factors, and incidence

Restorative proctocolectomy with ileal pouch-anal anastomosis has been the surgical treatment of choice for patients with ulcerative colitis who require surgery. Quality of life after this procedure is satisfactory in most cases; however, pouchitis is a troublesome condition involving inflammation of the ileal pouch. When a patient presents with symptoms of pouchitis, such as increased bowel movements, mucous and/or bloody exudates, abdominal cramps, and fever, endoscopy is essential for a precise diagnosis. The proximal ileum and rectal cuff, as well as the ileal pouch, should be endoscopically observed. The reported incidence of pouchitis ranges from 14% to 59%, and antibiotic therapy is the primary treatment for acute pouchitis. Chronic pouchitis includes antibiotic-dependent and refractory pouchitis. Intensive therapy including antitumor necrosis factor antibodies and steroids may be necessary for antibiotic-refractory pouchitis, and pouch failure may occur despite such intensive treatment. Reported risk factors for the development of pouchitis include presence of extraintestinal manifestations, primary sclerosing cholangitis, non-smoking, and postoperative non-steroidal anti-inflammatory drug usage. In the present review, we focus on the diagnosis, endoscopic features, management, incidence, and risk factors of pouchitis in patients with ulcerative colitis who underwent ileal pouch-anal anastomosis.

Evaluation of dairy allergy among ulcerative colitis patients

The intestine is the largest mucosal organ of the body and also the first line immune homeostasis. Inflammatory bowel disease or IBD is divided into ulcerative colitis and Crohn's disease. One of the problems that can occur with UC is dietary allergy to some foods. This study aimed to evaluated the dairy allergy among patients with ulcerative colitis. This study is a Case - control study, that studied 72 patients with Ulcerative Colitis, after recording history of the disease, colonoscopy and confirmed by biopsy and 72 person without history of colitis. In this study, in order to investigate of food allergy, used of the EUROMMUM kit with an international code number DP3420-1601-11E. We used chi-square and Monte Carlo method for analysis of data. Among UC patients, 30.6% mild, 52.8% moderate and 16.6% of cases were in sever stage. 9.7% of them reported a history of abdominal surgery due to disease. According to the chi-square and Monte Carlo methods, dairy allergy (including: cow milk, cow milk UHT and casein) in UC group was significant (P=0.00). This study indicated that there is significant relationship between UC and cow milk, cow milk UHT and casein. UC patients who are allergic to dairy products and the use of dairy products can increase the severity of UC.
