Pouch functional outcomes after restorative proctocolectomy with ileal-pouch reconstruction in patients with ulcerative colitis: Japanese multi-center nationwide cohort study

BACKGROUND

Although several complications capable of causing pouch failure may develop after restorative proctocolectomy (RPC) for ulcerative colitis (UC), the incidences and causes are conflicting and vary according to country, race and institution. To avoid pouch failure, this study aimed to evaluate the rate of pouch failure and its risk factors in UC patients over the past decade via a nationwide cohort study.

METHODS

We conducted a retrospective, observational, multicenter study that included 13 institutions in Japan. Patients who underwent RPC between January 2005 and December 2014 were included. The characteristics and backgrounds of the patients before and during surgery and their postoperative courses and complications were reviewed.

RESULTS

A total of 2376 patients were evaluated over 6.7 ± 3.5 years of follow-up. Twenty-seven non-functional pouches were observed, and the functional pouch rate was 98.9% after RPC. Anastomotic leakage (odds ratio, 9.1) was selected as a risk factor for a non-functional pouch. The cumulative pouch failure rate was 4.2%/10 years. A change in diagnosis to Crohn's disease/indeterminate colitis (hazard ratio, 13.2) was identified as an independent risk factor for pouch failure.

CONCLUSION

The significant risk factor for a non-functional pouch was anastomotic leakage. The optimal staged surgical procedure should be selected according to a patient's condition to avoid anastomotic failure during RPC. Changes in diagnosis after RPC confer a substantial risk of pouch failure. Additional cohort studies are needed to obtain an understanding of the long-standing clinical course of and proper treatment for pouch failure.

MRI defecography of the ileal pouch-anal anastomosis-contributes little to the understanding of functional outcome

PURPOSE

Variability in functional outcome after ileal pouch-anal anastomosis (IPAA) is to a large extent unexplained. The aim of this study was to use MRI to evaluate the morphology, emptying pattern and other pathology that may explain differences in functional outcome between well-functioning and poorly functioning pouch patients. A secondary aim was to establish a reference of normal MRI findings in pelvic pouch patients.

METHODS

From a previous study, the best and worst functioning patients undergoing IPAA surgery between 2000 and 2013 had been identified and examined with manovolumetric tests (N = 47). The patients were invited to do a pelvic MRI investigating pouch morphology and emptying patterns, followed by a pouch endoscopy.

RESULTS

Forty-three patients underwent MRI examination. We found no significant morphological or dynamic differences between the well-functioning and poorly functioning pouch patients. There was no correlation between urge volume and the volume of the bony pelvis, and no correlation between emptying difficulties or leakage and dynamic MRI findings. Morphological MRI signs of inflammation were present in the majority of patients and were not correlated to histological signs of inflammation. Of the radiological signs of inflammation, only pouch wall thickness correlated to endoscopic pouchitis disease activity index scores.

CONCLUSION

It seems MRI does not increase the understanding of factors contributing to functional outcome after ileal pouch-anal anastomosis. Unless there is a clinical suspicion of perianal/peripouch disease or pelvic sepsis, MRI does not add value as a diagnostic tool for pelvic pouch patients. Endoscopy remains the golden standard for diagnosing pouch inflammation.

Impact of sex on 30-day complications and long-term functional outcomes following ileal pouch-anal anastomosis for chronic ulcerative colitis

PURPOSE

To determine the impact of patient sex on operative characteristics, short-term complications, and long-term functional outcomes following ileal pouch-anal anastomosis (IPAA) for chronic ulcerative colitis (CUC).

METHODS

A retrospective review was performed on all patients undergoing two- or three-stage IPAA for CUC at our institution between January 2002 and August 2013. Patient demographics, operative characteristics, 30-day postoperative complications, and long-term functional outcomes from annual survey data were analyzed comparing men and women patients.

RESULTS

During the study period, 911 IPAAs (542 men, 369 women) were performed. Men were older and were more often obese (both p < 0.01). Use of a three-stage approach and laparoscopic approach were similar between men and women, but operation length, intraoperative blood loss, and hospital length of stay were all higher in men (all p < 0.05). At 30 days, women had increased rates of superficial surgical site infections and urinary tract infections (both p < 0.05), while men had increased rates of urinary retention (p = 0.03). Five hundred forty-six patients (60%; 307 men, 239 women) responded to the annual post IPAA survey with a median follow-up of 5.1 and 5.0 years in men and women, respectively. Women reported increased frequency of daytime stools in the early follow-up period, but this difference resolved with time. Other functional outcomes were similar.

CONCLUSION

Patient sex impacts intraoperative complexity, postoperative length of stay, 30-day postoperative outcomes, and initial long-term function. These findings underscore the need to adjust preoperative counseling regarding IPAA outcomes based on sex.

Clinical Implication of Enlarged Prostate in Patients with the Ileal Pouch-anal Anastomosis for Inflammatory Bowel Disease

Background

Enlarged prostate is often noticed in patients with ileal pouch-anal anastomosis (IPAA) in our clinical practice. The aims were to identify the factors associated with enlarged prostate and to investigate its clinical implications.

Methods

IPAA patients with available prostate imaging after IPAA were included. Prostate length and width were measured in the axial plane and height in coronal plane. Prostate volume was calculated with the formula (length × width × height) × π/6. A volume greater than 40 cm³ was used to define enlarged prostate.

Results

Prostate enlargement was found in 58 (24.8%) out of 234 patients. Factors associated with prostate enlargement included advanced age at imaging examination (55.6 ± 11.5 vs. 41.3 ± 13.6 years, P < 0.0001), age at pouch surgery (46.0 ± 11.8 vs. 32.5 ± 12.9 years, P<0.0001), and the presence of an S-pouch (6.9% vs. 1.1%, P = 0.03). Postoperative use of biologics was less common in patients with enlarged prostate (5.2% vs. 17%, P = 0.03). However, pouch duration was comparable (10.0 ± 5.9 vs. 8.8 ± 6.8 years, P = 0.2) and pouch failure rate was similar. A trend towards an increased risk for acute pouchitis in patients with enlarged prostate was noticed (19% vs. 9.1%, P = 0.06). The association of S-pouch (odds ratio: 7.2, 95% confidence interval: 1.1 - 46.4) and enlarged prostate remained significant after adjusting for age, acute pouchitis, and redo pouch on multivariate analysis.

Conclusions

Prostate enlargement appears to be uncommon after IPAA and it was associated with S-pouch configuration and advanced age. Enlarged prostate in the setting of IPAA does not seem to have adverse impact on pouch outcomes, although there is a trend in correlation between enlarged prostate and acute pouchitis.

Endoluminal vacuum-assisted therapy as treatment for anastomotic leak after ileal pouch-anal anastomosis: a pilot study

BACKGROUND

Anastomotic leak after ileal pouch-anal anastomosis (IPAA) could lead to poor functional results and failure of the pouch. The aim of the present study was to analyze the outcomes of the vacuum-assisted closure therapy as the unique treatment for anastomotic leaks following IPAA without any additional surgical operations.

METHODS

Consecutive patients with anastomotic leak after IPAA treated at our institution between March 2016 and March 2017 were prospectively enrolled. After diagnosis, the Endosponge^® device was positioned in the gap and replaced until the cavity was reduced in size and covered by granulating tissue. A pouchoscopy was performed every week for the first month and monthly subsequently. No additional procedures were performed.

RESULTS

Eight patients were included in the study. The leak was diagnosed at a median of 14 (6-35) days after surgery. At the time of diagnosis, seven patients had a defunctioning ileostomy performed as routine at the time of pouch formation, while one patient was diagnosed after ileostomy closure and underwent emergency diversion ileostomy. The Endosponge^® treatment started after a median of 6.5 (1-158) days after the diagnosis of the leakage and was carried on for a median of 12 (3-42) days. The device was replaced a median of 3 (1-10) times. The median length of hospital stay after the first application of the treatment was 15.5 (6-48) days. The complete healing of the leak was documented in all patients, after a median of 60 (24-90) days from the first treatment. All patients but one had their ileostomy reversed at a median of 2.5 (1-6) months from the confirmation of the complete closure.

CONCLUSIONS

Endosponge^® is effective as the only treatment after IPAA leak. Based on the results of our prospective pilot study, application of Endosponge^® should be the treatment of choice in selected pouch anastomotic leaks not requiring immediate surgery. These results will have to be confirmed by future prospective studies including a larger number of patients.

Vedolizumab in the treatment of chronic, antibiotic-dependent or refractory pouchitis

BACKGROUND

The most common complication after ileal pouch anal anastomosis in up to 50% of patients is an acute pouchitis. The majority of patients respond to antibiotic treatment. However, 10%-15% develops chronic antibiotic-dependent or refractory pouchitis which is usually hard to treat.

AIM

To evaluate the effectiveness of vedolizumab in patients with chronic pouchitis.

METHODS

Patients with chronic antibiotic-dependent or refractory pouchitis were treated with vedolizumab (300 mg at week 0, 2, 6 and 10) in 10 IBD centres and retrospectively registered. Data were recorded until week 14 of vedolizumab treatment. In total 20 patients (12 male, median age 43 years) were included for analysis. The effectiveness was measured using the Oresland Score (OS) at week 2, 6, 10 and 14 and the pouch disease activity index (PDAI) at week 0 and 14.

RESULTS

The mean OS declined from 6.8 (range 2-12) to 3.4 (range 0-11). Concordantly, the mean PDAI after 14 weeks of treatment dropped from 10 (range 5-18) to 3 (range 0-10). Only three patients reported moderate side effects. No serious side effects were recorded. In addition, symptomatic co-medication such as loperamide and tincture of opium could be terminated in 8 out of 12 patients as well as antibiotic treatment could be stopped in 17 out of 19 patients.

CONCLUSION

Our data indicate that vedolizumab could be an option in the treatment of patients with chronic, antibiotic-dependent or refractory pouchitis.

Evidence-based clinical practice guidelines for inflammatory bowel disease

Inflammatory bowel disease (IBD) is a chronic disorder involving mainly the intestinal tract, but possibly other gastrointestinal and extraintestinal organs. Although etiology is still uncertain, recent knowledge in pathogenesis has accumulated, and novel diagnostic and therapeutic modalities have become available for clinical use. Therefore, the previous guidelines were urged to be updated. In 2016, the Japanese Society of Gastroenterology revised the previous versions of evidence-based clinical practice guidelines for ulcerative colitis (UC) and Crohn's disease (CD) in Japanese. A total of 59 clinical questions for 9 categories (1. clinical features of IBD; 2. diagnosis; 3. general consideration in treatment; 4. therapeutic interventions for IBD; 5. treatment of UC; 6. treatment of CD; 7. extraintestinal complications; 8. cancer surveillance; 9. IBD in special situation) were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases. The guidelines were developed with the basic concept of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Recommendations were made using Delphi rounds. This English version was produced and edited based on the existing updated guidelines in Japanese.

Segmental Resection versus Total Proctocolectomy for Crohn's Colitis: What is the Best Operation in the Setting of Medically Refractory Disease or Dysplasia?

Crohn's disease (CD) may affect any part of the gastrointestinal tract. When isolated to the colon, and patients become medically refractory, there are several surgical options - segmental resection, subtotal colectomy with ileorectal anastomosis, or a total proctocolectomy and end ileostomy. Unfortunately, surgery does not cure CD, and, regardless of the extent of bowel removed, recurrence may be seen in the small bowel. This may lead to need for further immunosuppression or surgery. Therefore, when appropriate, a segmental colectomy or subtotal colectomy may prevent a permanent ostomy required with a total proctocolectomy. In the setting of dysplasia identified on colonoscopy, low quality evidence guides our treatment paradigms. Even though identification of dysplasia has greatly improved with chromoendoscopy, rates of synchronous or metachronous neoplasm remain high. Thus, a total proctocolectomy and end ileostomy, whereas a larger operation, may be best for the patient to remove all at risk tissue. Further research with prospective or randomized control trials is needed to improve our practice guidelines of both scenarios.

Feasibility of restorative proctocolectomy in patients with ulcerative colitis-associated lower rectal cancer: A retrospective study

BACKGROUND/OBJECTIVE

Restorative proctocolectomy (RP) may improve quality of life in patients with ulcerative colitis (UC)-associated lower rectal cancer to a greater extent than total proctocolectomy. However, patients with UC-associated cancer often have flat mucosal lesions that make it extremely difficult to endoscopically delineate the tumor margins. Therefore, there is a potential risk of residual tumor and local recurrence after RP in patients with UC-associated lower rectal cancer. The aim of this study was to assess the feasibility of RP in patients with UC-associated cancer of the lower rectum.

METHODS

We retrospectively identified nine patients who had undergone RP for UC-associated lower rectal cancer at the Niigata University Medical and Dental Hospital between January 2000 and December 2016. The incidence of flat mucosal cancer, distal margin status, and oncologic outcomes were evaluated in the nine patients.

RESULTS

Eight (89%) of the nine patients had flat mucosal cancer in the lower rectum. The median length of the distal margin was 22 mm (range 0-55 mm). No patient developed local or distant recurrence during follow-up. One patient had a positive distal margin. This patient underwent annual pouchoscopy, but had no local recurrence and died of pancreatic cancer 81 months after RP. The remaining eight patients were alive at the final observation. Five-year and 10-year overall survival rates in the nine patients were 100% and 66.7%, respectively.

CONCLUSION

Patients with UC-associated lower rectal cancer often have lesions of the flat mucosal type. However, RP is feasible and not necessarily contraindicated in such patients.

Outcome of restorative proctocolectomy with an ileo-anal pouch for ulcerative colitis: effect of changes in clinical practice

AIM

Surgery for ileal pouch-anal anastomosis (IPAA) has evolved over time, especially since the introduction of laparoscopy. The aim of this retrospective study was to report the impact of surgical evolution on outcome over a period of 25 years.

METHOD

All patients who had IPAA surgery for ulcerative colitis from 1990 to 2015 at the University Hospitals of Leuven were included. Patients were divided into three period arms (period A 1990-1999; period B 2000-2009; period C 2010-2015). The main outcome measure was anastomotic leakage.

RESULTS

A total of 335 patients (58.8% male) with a median age of 39 years (interquartile range 32-49 years) at surgery were included. Median follow-up was 5 years (interquartile range 2-10 years). Overall anastomotic leakage (grades A-C) was 14.9%. A significant decrease in leakage rate was observed over time (from 21.4% in period A to 12.1% in period B to 10.0% in period C; P = 0.04). The defunctioning ileostomy rate at the time of pouch construction decreased from 91.7% (period A) to 40.3% (period B) to 11.1% (period C) (P < 0.001). We observed an increase in the use of laparoscopy (23.9% in period A vs 72.6% in period B, vs 84.4% in period C; P = 0.001) and a shift to a modified two-stage procedure (4.1% in period A, vs 66.7% in period C; P < 0.0001). In a monocentric study with some of the data retrieved retrospectively it was not possible to account for the impact of preoperative nutritional status (weight loss, serum albumin level) or disease burden. Other outcome factors were not measured, for example sexual function and fecundity.

CONCLUSION

A higher rate of laparoscopic IPAA surgery, together with a shift towards modified two-stage procedures, was associated with a lower leakage rate despite a reduction in the use of defunctioning ileostomy.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Assessing the Optimal Position for Vedolizumab in the Treatment of Ulcerative Colitis: A Simulation Model

BACKGROUND

Vedolizumab, an α4β7 integrin monoclonal antibody inhibiting gut lymphocyte trafficking, is an effective treatment for ulcerative colitis (UC). We evaluated the optimal position of vedolizumab in the UC treatment paradigm.

METHODS

Using Markov modeling, we assessed multiple algorithms for the treatment of UC. The base case was a 35-year-old male with steroid-dependent moderately to severely active UC without previous immunomodulator or biologic use. The model included 4 different algorithms over 1 year, with vedolizumab use prior to: initiating azathioprine (Algorithm 1), combination therapy with infliximab and azathioprine (Algorithm 2), combination therapy with an alternative anti-tumor necrosis factor (anti-TNF) and azathioprine (Algorithm 3), and colectomy (Algorithm 4). Transition probabilities and quality-adjusted life-year (QALY) estimates were derived from the published literature. Primary analyses included simulating 100 trials of 100,000 individuals, assessing clinical outcomes, and QALYs. Sensitivity analyses employed longer time horizons and ranges for all variables.

RESULTS

Algorithm 1 (vedolizumab use prior to all other therapies) was the preferred strategy, resulting in 8981 additional individuals in remission, 18 fewer cases of lymphoma, and 1087 fewer serious infections per 100,000 patients compared with last-line use (A4). Algorithm 1 also resulted in 0.0197 to 0.0205 more QALYs compared with other algorithms. This benefit increased with longer time horizons. Algorithm 1 was preferred in all sensitivity analyses.

CONCLUSION

The model suggests that treatment algorithms positioning vedolizumab prior to other therapies should be considered for individuals with moderately to severely active steroid-dependent UC. Further prospective research is needed to confirm these simulated results.

A look at the smelly side of physiology: transport of short chain fatty acids

Fermentative organs such as the caecum, the colon, and the rumen have evolved to produce and absorb energy rich short chain fatty acids (SCFA) from otherwise indigestible substrates. Classical models postulate diffusional uptake of the undissociated acid (HSCFA). However, in net terms, a major part of SCFA absorption occurs with uptake of Na⁺ and resembles classical, coupled electroneutral NaCl transport. Considerable evidence suggests that the anion transporting proteins expressed by epithelia of fermentative organs are poorly selective and that their main function may be to transport acetate^-, propionate^-, butyrate^- and HCO₃^- as the physiologically relevant anions. Apical uptake of SCFA thus involves non-saturable diffusion of the undissociated acid (HSCFA), SCFA^-/HCO₃^- exchange via DRA (SLC26A3) and/or SCFA^--H⁺ symport (MCT1, SLC16A1). All mechanisms lead to cytosolic acidification with stimulation of Na⁺/H⁺ exchange via NHE (SLC9A2/3). Basolaterally, Na⁺ leaves via the Na⁺/K⁺-ATPase with recirculation of K⁺. Na⁺ efflux drives the transport of SCFA^- anions through volume-regulated anion channels, such as maxi-anion channels (possibly SLCO2A1), LRRC8, anoctamins, or uncoupled exchangers. When luminal buffering is inadequate, basolateral efflux will increasingly involve SCFA^-/ HCO₃^- exchange (AE1/2, SCL4A1/2), or efflux of SCFA^- with H⁺ (MCT1/4, SLC16A1/3). Furthermore, protons can be basolaterally removed by NHE1 (SCL9A1) or NBCe1 (SLC4A4). The purpose of these transport proteins is to maximize the amount of SCFA transported from the tightly buffered ingesta while minimizing acid transport through the epithelium. As known from the rumen for many decades, a disturbance of these processes is likely to cause severe colonic disease.

Determinants of optimal bowel function in ileal pouch-anal anastomosis - physiological differences contributing to pouch function

BACKGROUND

Variability in functional outcome after ileal-pouch anal anastomosis (IPAA) is to a large extent unexplained. The aim of this study was to perform multiple physiological and biochemical tests including an endoscopic examination with histology on IPAA patients with well and poorly functioning pouches to determine factors, or combinations thereof, contributing to functional outcome.

METHODS

All patients with ulcerative colitis undergoing restorative proctocolectomy between 2000 and 2013 (N = 108) were interviewed using a pouch functioning score. The best and worst functioning quartiles were invited to undergo examination with a barostat measuring pouch volume at preset variable distension pressures, and a pouch endoscopy.

RESULTS

Forty five of 58 eligible patients agreed to participate. The most significant physiological parameter differing between the well and poorly functioning pouches was pouch volume at first sensation, urge and discomfort (p value <.001). Urge volumes were 213 (CI 171-256) ml for poorly and 352 (CI 305-401) ml for well functioning pouches. Pouchitis episodes were negatively correlated to function. The poorly functioning patients had a higher prevalence of histological signs of inflammation and hand-sewn anastomosis, and a longer remaining rectal cuff, however, nonsignificant. The pouch pressure at sensation thresholds did not differ between the groups.

CONCLUSIONS

Pouch volume is the most dominant predictor of pouch function in this study. The present comprehensive study of a multitude of different factors that possibly could be contributing to functional outcome, failed to shed much further light on the functional variability among pouch patients. The pouch physiology remains to a large extent unexplained.

The functional outcome and factors influencing the quality of life after ileal pouch anal anastomosis in patients with ulcerative colitis

PURPOSE

The aim of this study was to assess the bowel function and quality of life (QOL) in patients with ulcerative colitis (UC) after total proctocolectomy with ileal pouch anal anastomosis (IPAA).

METHODS

Two questionnaires ["Questionnaire sheet on the bowel function" and "Inflammatory bowel disease questionnaire (Japanese IBDQ)"] were sent to 121 patients with UC who underwent IPAA at Tohoku University Hospital. Seventy-nine patients (65%) participated in the study.

RESULTS

The median number of daily bowel movements was 6.5, which significantly decreased with postoperative time (≤ 1, 1-5, 5-15 years) and increased with age (< 45, ≥ 45 years at colectomy). The ratio of patients who usually had bowel movements at night also significantly decreased with postoperative time and increased with age. The median total IBDQ score was 180. A multivariate analysis showed that "trip activity", "care about where the restroom is", and "bowel movements in the day" were significant independent risk factors for the daily life satisfaction score.

CONCLUSIONS

The bowel function and QOL were acceptable in patients with UC after IPAA; however, patients with a short postoperative time or older age had a lower functional outcome than others.

Impact of Prostate Cancer and Its Treatment on the Outcomes of Ileal Pouch-Anal Anastomosis

BACKGROUND

There are scant published data in the impact of prostate cancer and its treatment on functional outcomes and quality of life (QOL) in patients with ileal pouch-anal anastomosis (IPAA). The aim of the study was to evaluate the influence of prostate cancer and its treatment on functional outcomes and QOL in patients with IPAA.

METHODS

Patients with IPAA with prostate cancer were compared to age and pouch duration-matched controls without prostate cancer in a 1:2 ratio. Pouch function and QOL were compared between pretreatment and posttreatment for prostate cancer as well as between subjects and controls.

RESULTS

A total of 30 patients with IPAA with prostate cancer and 60 matched controls were included. Treatment modalities of prostate cancer included prostatectomy (n = 22), brachytherapy (n = 5), watchful waiting (n = 2), and hormonal therapy (n = 1). The median length of follow-up was 6 (interquartile range, 2.7-8) years. Permanent fecal diversion was required in 5 (16.7%) patients with prostate cancer who developed pouch failure, as compared with 2 patients in the control group (P = 0.04). In patients who retained their pouches, the pouch functional outcomes at the latest follow-up were similar to that before prostate cancer treatment and to that of the matched controls, in terms of bowel movements, daytime seepage, nighttime bowel movements, nighttime seepage, and QOL score.

CONCLUSIONS

The risk of pouch failure may be increased after the diagnosis of prostate cancer with or without treatment. However, for those with retained pouches, their pouch function and QOL did not seem to be adversely affected.

Risk Factors for Postoperative Complications Following Diverting Loop Ileostomy Takedown

INTRODUCTION

Diverting loop ileostomies are frequently created to divert the fecal stream in an effort to protect downstream anastomoses. These are later reversed to restore intestinal continuity. The goal of this study is to evaluate risk factors for postoperative complications following diverting loop ileostomy takedown.

MATERIALS AND METHODS

Patients who underwent diverting loop ileostomy takedown between January 1, 2010 and April 28, 2015 were identified in the Michigan Surgical Quality Collaborative registry. Candidate covariates were identified and a hierarchical logistic regression model was used to identify risk factors for postoperative complications.

RESULTS

1,737 patients met the inclusion criteria. Rates of postoperative complications were generally low. Mean length of stay (LOS) was 5.6 (± 4.5) days. Outcomes of interest were the following: overall morbidity, serious morbidity, extended LOS, SSI, UTI, pneumonia, readmission, reoperation, and mortality. Risk factors for these outcomes included the following: ASA class, bleeding disorder, prolonged operative time, race, tobacco use, gender, steroid use, peripheral vascular disease, weight loss, and functional status.

CONCLUSIONS

Diverting loop ileostomy takedown has a complication rate of approximately 20%. Higher ASA class, longer operative times, history of bleeding disorder, and functional status were identified as risk factors for most complications.

Complications in children with ulcerative colitis undergoing ileal pouch-anal anastomosis

Total colectomy with ileal pouch-anal anastomosis (IPAA) is considered the standard procedure for the surgical management of ulcerative colitis. Despite the widespread utility of the procedure, as many as 75% of patients who undergo IPAA, experience at least 1 complication. This review highlights difficult intraoperative scenarios and complications of pouch surgery in children, including intraoperative, postoperative, and functional complications. Intraoperative scenarios include insufficient mesenteric length and positive leak tests. Postoperative complications include surgical site infection, anastomotic leak, stricture, fistula, pouchitis, small bowel obstruction, and pouch failure. Less common complications include afferent limb syndrome, pouch prolapse, and superior mesenteric artery syndrome. Functional complications include incontinence, impaired quality of life, infertility, and sexual dysfunction. Despite complications, most patients are satisfied with their outcomes and report an improvement in their lifestyle.

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.

Transanal Versus Transabdominal Minimally Invasive (Completion) Proctectomy With Ileal Pouch-anal Anastomosis in Ulcerative Colitis: A Comparative Study

OBJECTIVE

This study aims to compare surgical outcome of transanal ileal pouch-anal anastomosis (ta-IPAA) with transabdominal minimal invasive approach in ulcerative colitis (UC), using the comprehensive complication index (CCI).

BACKGROUND

Recent evolutions in rectal cancer surgery led to transanal dissection of the rectum resulting in a better exposure of the distal rectum and presumed better outcome. The same approach was introduced for patients with UC, resulting in decreased invasiveness.

METHODS

All patients, undergoing minimally invasive restorative proctocolectomy in 1, 2, or 3 stages between January 2011 and September 2016 in 3 referral centers were included. Only patients who underwent either multiport, single port, single port with 1 additional port, hand-assisted, or robotic (R) laparoscopy were included in the analysis. CCI, registered during 90 days after pouch construction, was compared between the transanal and the transabdominal approach.

RESULTS

Ninety-seven patients (male: 52%) with ta-IPAA were compared to 119 (male: 53%) with transabdominal IPAA. Ninety-nine (46%) patients had a defunctioning ileostomy at time of pouch construction. A 2-step model showed that the odds for postoperative morbidity were 0.52 times lower in the ta-IPAA group (95% confidence interval [0.29; 0.92] P = 0.026). In patients with morbidity, mean CCI of the transanal approach was 2.23 points lower than the transabdominal approach (95% confidence interval: [-6.64-3.36] P = 0.13), which was not significant.

CONCLUSIONS

Ta-IPAA for UC is a safe procedure, resulting in fewer patients with morbidity, but comparable CCI when morbidity is present. Overall, ta-IPAA led to lower CCI scores.

Restorative proctocolectomy: an example of how surgery evolves in response to paradigm shifts in care

AIM

Surgical technique constantly evolves in response to the pressure of progress. Ileal pouch anal anastomosis (IPAA) is a good example. We analysed the effect of changes in practice on the technique of IPAA and its outcomes.

METHOD

Patients undergoing primary IPAA at this institution were divided into three groups by date of the IPAA: those operated from 1983 to 1993, from 1994 to 2004 and from 2005 to 2015. Demographics, patient comorbidity, surgical techniques, postoperative outcomes, pouch function and quality of life were analysed.

RESULTS

In all, 4525 patients had a primary IPAA. With each decade, increasing numbers of surgeons were involved (decade I, 8; II, 16; III, 31), patients tended to be sicker (higher American Society of Anesthesiologists score) and three-staged pouches became more common. After an initial popularity of the S pouch, J pouches became dominant and a mucosectomy rate of 12% was standard. The laparoscopic technique blossomed in the last decade. 90-day postoperative morbidity by decade was 38.3% vs 50% vs 48% (P < 0.0001), but late morbidity decreased from 74.2% through 67.1% to 30% (P < 0.0001). Functional results improved, but quality of life scores did not. Pouch survival rate at 10 years was maintained (94% vs 95.2% vs 95.2%; P = 0.06).

CONCLUSION

IPAA is still evolving. Despite new generations of surgeons, a more accurate diagnosis, appropriate staging and the laparoscopic technique have made IPAA a safer, more effective and enduring operation.

Colectomy in refractory Crohn's colitis improves nutrition and reduces steroid use

BACKGROUND

Pediatric patients with severe refractory Crohn's colitis (CC) may require total colectomy (TC) or diverting loop ileostomy (DLI). Our understanding of outcomes (postoperative complications, nutrition and restoration of intestinal continuity) is currently limited.

METHODS

Pediatric patients with severe CC who underwent TC or DLI were identified. Demographics, pre and postoperative anthropometric and biochemical data, surgical complications and medication requirements were recorded.

RESULTS

Twenty-seven patients (TC=22, DLI=5) with a median age of 15.0years (range 3-18) were identified, 64% male with a median follow-up of 45months (range 3-120). Mean weight and BMI improved for TC patients by 1year postoperatively - weight z-score from -1.08 to -0.54 (p=0.02), BMI z-score from -0.83 to -0.38 (p=0.04), with a non-significant height change from - 0.79 to -0.65 (p=0.07). Mean hemoglobin and albumin both also improved - 9.88g/dl to 11.76g/dl (p=0.003) and 3.44g/dl to 4.03g/dl (p=0.004) respectively. These measures did not significantly improve after DLI. Most TC patients (59%) had attempted restoration of intestinal continuity with 45% in continuity at end of follow-up. One DLI patient underwent ileostomy takedown but subsequently needed re-diversion.

CONCLUSIONS

In severe CC, TC offers an opportunity to improve nutrition and growth, with a reasonable likelihood of restoring intestinal continuity.

Factors affecting pouch-related outcomes after restorative proctocolectomy

Purposes

Restorative proctocolectomy (RPC) with ileal pouch anal anastomosis (IPAA) is the procedure of choice for patients with familial adenomatous polyposis (FAP) and ulcerative colitis (UC) despite morbidities that can lead to pouch failure. We aimed to identify factors associated with pouch-related morbidities.

Methods

A retrospective analysis of patients who underwent RPC with IPAA was performed. To investigate the factors associated with pouch-related morbidities, patients' preoperative demographic and clinical factors, and intraoperative factors were included in the analysis.

Results

A total of 49 patients with UC, FAP, and colorectal cancer were included. Twenty patients (40.8%) experienced leakage-related, functional, and/or pouchitis-related morbidities. Patients with American Society of Anesthesiologists (ASA) grade 2 or 3 had a higher risk of functional morbidity than those with grade 1. Intraoperative blood loss exceeding 300.0 mL was associated with an increased risk of pouchitis-related morbidity.

Conclusions

Our study demonstrated associations of higher ASA grade and increased intraoperative blood loss with poor functional outcomes and pouchitis, respectively.

Risk of Colectomy in Patients With Pediatric-onset Ulcerative Colitis

OBJECTIVES

Data describing the incidence and risk factors for colectomy in pediatric ulcerative colitis (UC) is inconsistent. Our aim was to describe the colectomy rate and to identify risk factors associated with colectomy in a large cohort of children with UC with long-term follow-up.

MATERIALS AND METHODS

We performed a retrospective chart review of pediatric UC cases that were diagnosed at Schneider Children's Medical Center of Israel between 1981 and 2013. Potential predictors for colectomy including age at diagnosis, sex, disease extent, severity indices, and different therapeutic regimens during disease course were assessed.

RESULTS

Of 188 patients with pediatric onset UC, 34 (18%) underwent colectomy. Median follow-up was 6.9 years (range, 1-30). Kaplan-Meier survival estimates of the cumulative probability for colectomy were 4% at 1 year and 17% at 10 years from diagnosis. Multivariate Cox models showed that male sex (hazard ratio 4.2, P = 0.001) and severe disease at diagnosis reflected by Pediatric Ulcerative Colitis Activity Index score ≥65 (hazard ratio 8.9, P < 0.001) were associated with increased risk for colectomy. Age, disease extent, ethnicity, family history of inflammatory bowel disease, early introduction of immunomodulators, or treatment with antitumor necrosis factor α agent did not affect the risk of colectomy.

CONCLUSIONS

Male sex and higher Pediatric Ulcerative Colitis Activity Index score at diagnosis are independent risk factors for colectomy.

Outcome after restorative proctocolectomy and ileal pouch–anal anastomosis in children and adults

Background

Studies comparing the outcome of ileal pouch–anal anastomosis (IPAA) in children and adults are scarce. This complicates decision-making in young patients. The aim of this study was to compare adverse events and pouch function between children and adults who underwent IPAA.

Methods

This cross-sectional cohort study included all consecutive children (aged less than 18 years) and adults with a diagnosis of inflammatory bowel disease or familial adenomatous polyposis who underwent IPAA in a tertiary referral centre between 2000 and 2015. Adverse events were assessed by chart review, and pouch function by interview using a pouch function score (PFS).

Results

In total, 445 patients underwent IPAA: 41 children (median age 15 years) and 404 adults (median age 39 years), with a median follow-up of 22 (i.q.r. 8–68) months. Being overweight (P = 0·001), previous abdominal surgery (P = 0·018), open procedures (P &lt; 0·001) and defunctioning ileostomy (P = 0·014) were less common among children than adult patients. The occurrence of anastomotic leakage, surgical fistulas, chronic pouchitis and Crohn's of the pouch was not associated with paediatric age at surgery, nor was pouch failure. The development of anastomotic strictures was associated with having IPAA surgery during childhood (odds ratio 4·22, 95 per cent c.i. 1·13 to 15·77; P = 0·032). Pouch function at last follow-up was similar in the children and adult groups (median PFS 5·0 versus 6·0 respectively; P = 0·194).

Conclusion

Long-term pouch failure rates and pouch function were similar in children and adults. There is no need for a more cautious attitude to use of IPAA in children based on concerns about poor outcome.

Alicaforsen in the treatment of pouchitis

Alicaforsen is a 20-base antisense oligonucleotide inhibiting ICAM-1 production, which is an important adhesion molecule involved in leukocyte migration and trafficking to the site of inflammation. Hitherto, alicaforsen has been granted orphan drug designation and is prescribed as an unlicensed medicine in accordance with international regulation for the treatment of pouchitis and left-sided ulcerative colitis. Given the positive results evolving from one open-label trial and one case series in patients with chronic refractory pouchitis, US FDA has agreed to a rolling submission for a license application for the treatment of pouchitis, which has been recently initiated. Whether alicaforsen leads to higher endoscopic and clinical remission rates as placebo and whether the response can be maintained in the long-term in larger studies is yet unknown. An ongoing multicenter international Phase III trial will definitely address these unanswered questions.

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.

Predictors of pouchitis after ileal pouch-anal anastomosis in pediatric-onset ulcerative colitis

OBJECTIVES

Few studies have reported on the incidence and risk factors for pouchitis following colectomy and ileal pouch-anal anastomosis (IPAA) in patients with pediatric-onset ulcerative colitis (UC). We aimed to determine clinical predictors for the development of pouchitis following IPAA in this population.

PATIENTS AND METHODS

We performed a retrospective chart review of all pediatric UC cases that were diagnosed at the Schneider Children's Medical Center of Israel between 1981 and 2013 and who underwent colectomy during disease course. Potential predictors for pouchitis and chronic pouchitis including various demographic, clinical, endoscopic, and histological variables at diagnosis and at the time of surgery were assessed.

RESULTS

Of 188 patients with pediatric-onset UC, 33 (18%) underwent colectomy and IPAA surgery. During a median postsurgical follow-up of 7.6 (range: 1-21.5) years following IPAA, 20/33 (60%) patients developed pouchitis including 11/33 (33%) patients who developed chronic pouchitis. Kaplan-Meier survival estimates of the cumulative probability for pouchitis were 9% at 1 year and 36 and 55% at 5 and 10 years, respectively. Multivariate Cox models showed that older age at colectomy (hazard ratio: 0.86, P=0.024) was a protective factor, whereas preoperative vitamin-D deficiency (≤20 ng/ml) (hazard ratio: 4.4, P=0.021) increased the risk for pouchitis. Age at diagnosis, sex, disease extent, and preoperative therapeutic regimens did not affect the risk of pouchitis.

CONCLUSION

Long-term risk for pouchitis is significantly high in pediatric-onset UC after IPAA. Vitamin-D deficiency and younger age at colectomy may increase the risk for pouchitis.

[Laparoscopic proctocolectomy technique : Restorative proctocolectomy with ileal pouch-anal anastomosis in ulcerative colitis. Video article]

Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) constitutes a curative treatment option for therapy-refractory ulcerative colitis. A two-stage procedure with loop ileostomy at the time of IPAA is the most frequent variant of surgery. The aim of the procedure is the complete removal of the colon and rectum with simultaneous restoration of gastrointestinal continuity and preservation of continence functions. Long-term quality of life following laparoscopic proctocolectomy with IPAA is good and comparable with a healthy reference population. The surgical technique is demonstrated in detail with the help of a video of the operation, which is available online.

Nonrelaxing Pelvic Floor Dysfunction Is an Underestimated Complication of Ileal Pouch-Anal Anastomosis

BACKGROUND & AIMS

Nonrelaxing pelvic floor dysfunction (N-RPFD), or dyssynergic defecation, is the paradoxical contraction and/or impaired relaxation of pelvic floor and anal muscles during defecation. Few studies have evaluated this disorder in patients with an ileal pouch-anal anastomosis (IPAA). We investigated the frequency of N-RPFD in patients with and without chronic pouchitis following IPAA and the effectiveness of biofeedback therapy within this population.

METHODS

We conducted a retrospective study of all patients with an IPAA who underwent anorectal manometry between January 2000 and March 2015 (n = 111). N-RPFD was diagnosed in patients with symptoms consistent with a pouch evacuation disorder and 1 or more of the following abnormal tests: anorectal manometry, balloon expulsion test, barium or magnetic resonance defecography, or external anal sphincter electromyography. Patients who completed biofeedback therapy were identified and assessed to determine symptomatic response.

RESULTS

Of the 111 patients evaluated, 83 (74.8%) met criteria for N-RPFD. A significantly higher proportion of patients with chronic pouchitis were diagnosed with N-RPFD than patients without chronic pouchitis (83.3% vs 62.2%, respectively; P = .012). Most patients diagnosed with N-RPFD had abnormal results from the balloon expulsion test (78.3%); 53.0% of patients diagnosed with N-RPFD had abnormal findings from external anal sphincter electromyography, 25.3% had abnormal defecography findings, and 20.5% had abnormal findings from anorectal manometry. Twenty-two patients completed biofeedback therapy: 15 patients (68.2%) had mild-moderate improvement and 5 patients (22.7%) had significant improvement of symptoms.

CONCLUSIONS

N-RPFD occurs in almost 75% of patients with an IPAA, especially in patients with chronic pouchitis. Biofeedback seems to be an effective therapy for patients with an IPAA and N-RPFD, but further studies are needed for validation.

Total abdominal colectomy vs. restorative total proctocolectomy as the initial approach to medically refractory ulcerative colitis

PURPOSE

There is scant data assessing the consequences of staging restorative proctocolectomy for ulcerative colitis. The aim of the study is to compare outcomes of initial vs. staged restorative proctocolectomy.

METHODS

Patients completing restorative proctocolectomy, including ileostomy reversal, during 2006-2012 were identified from an IRB-approved database. Demographics, treatment variables, and perioperative outcomes were assessed.

RESULTS

Out of 521 patients, 322 (62%) underwent initial total abdominal colectomy before restorative proctectomy. This group was associated with more common preoperative anemia, leukocytosis, hypoalbuminemia, severe colitis, steroids and biologics use, decreased proximal ileostomy rate at the time of completion restorative proctectomy (92.5 vs 97.5%, p = 0.023), shorter hospital stay (6.6 vs 7.8, p < 0.001), and marginally decreased pelvic sepsis rate (6.2 vs 11.1%, p = 0.05) compared with patients having initial restorative proctocolectomy. However, they also required longer combined postoperative hospital stays (17 vs 12 days, p < 0.001) and treatment span (10.4 vs 5.7 months, p < 0.001) to complete all surgical stages and they were associated with increased overall postoperative surgical site infection, hemorrhage, and small bowel obstruction rates. Pouch function and QOL were comparable between the groups, except for increased nightly bowel movements in the initial abdominal colectomy group (2.5 ± 2.2 vs 2.1 ± 1.8, p = 0.012).

CONCLUSIONS

Patients undergoing initial total abdominal colectomy require longer treatment time and experience increased overall morbidity, but ultimately experience comparable ileal pouch outcomes when compared to patients undergoing initial restorative proctocolectomy.

[How does the ileoanal pouch keep its promises? : Functioning of the ileoanal pouch after restorative proctocolectomy]

Restorative proctocolectomy with an ileoanal pouch anastomosis (IAPA) is the surgical therapy of choice for patients with refractory ulcerative colitis and/or associated (pre)neoplastic lesions. It is predominantly performed laparoscopically. Reconstruction with a J‑pouch is the most frequently applied variant due to the ideal combination of technical simplicity and good long-term results. In the present review, potential postoperative pouch complications, their risk factors, diagnostics and surgical management, as well as mid-term and long-term quality of life after pouch construction are differentially presented based on the current literature.

Postoperative complications after stapled and hand-sewn ileal pouch-anal anastomosis for familial adenomatous polyposis: A multicenter study

Ileal pouch‐anal anastomosis (IPAA) after total proctocolectomy (TPC) can be conducted with either hand‐sewn or stapled anastomosis for patients with familial adenomatous polyposis (FAP). Although stapled IPAA without mucosectomy has a higher risk for developing adenomas in the remnant mucosa, it is the simpler procedure with potential benefit in short‐term outcomes. However, it remains controversial as to whether stapled IPAA has any advantages in reducing postoperative complications. The aim of the present study was to compare the postoperative complications and short‐term outcomes of stapled and hand‐sewn IPAA for patients with FAP, using a multicenter cohort sample in Japan. Data of 143 patients with FAP who underwent TPC with stapled IPAA (n=37) and hand‐sewn IPAA (n=106) at 23 institutions between 2000 and 2012 were collected. Postoperative complications, proportion of ostomy, fecal continence and overall survival were compared. Overall rates of the Clavien‐Dindo grade II‐IV complications were not different between the two groups (19% in stapled vs 25% in hand‐sewn, P=.42), with significantly fewer pouch‐related complications including leakage, pelvic abscess, vaginal fistula and anastomotic stricture in stapled IPAA (none in stapled vs 11% in hand‐sewn, P=.036). There was no mortality. Proportion of ostomy at 12 months was similar (2.7% in stapled vs 4.3% in hand‐sewn, P=.26). Mean Wexner score was similar. (0.47 in stapled vs 2.0 in hand‐sewn, P=.12). Five‐year overall survival excluding Stage IV patients was 96% in both groups. Stapled IPAA is a safe option in patients with FAP with a potential benefit in reducing pouch‐related complications.

Hereditary Colorectal Cancer Syndromes

Awareness of hereditary colorectal cancer syndromes is important to facilitate their identification because affected patients are at increased risk for early onset, synchronous, and metachronous colorectal malignancies, and certain extracolonic malignancies depending on the syndrome. Identification of an affected individual allows for screening and early interventions for patients and their at-risk kindred. Genetic counseling and testing is important to the care of these patients. As knowledge of the genetic basis of these syndromes grows, unique genotype-phenotype profiles allow clinicians to tailor surveillance and treatment strategies based on individual risk.

Pouch-Related Symptoms and Quality of Life in Patients with Ileal Pouch-Anal Anastomosis

BACKGROUND

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the standard surgical treatment for the majority of patients with inflammatory bowel disease (IBD) who require colectomy. We evaluated the prevalence of pouch-related symptoms among the Crohn's and Colitis Foundation of America Partners cohort and the effect of pouch-related symptoms on Patient-Reported Outcome Measurement Information System measures.

METHODS

We performed analyses nested in the Crohn's and Colitis Foundation of America Partners cohort. We used bivariate analyses to compare demographics and medication use among patients with ulcerative colitis or indeterminate colitis and pouch-related symptoms and those with IPAA without symptoms. We also compared Patient-Reported Outcome Measurement Information System domains (measured in T-scores) and short IBD questionnaire quality of life scales between symptomatic pouch patients (over the past 6 mo) and those without symptoms.

RESULTS

Among 243 patients reporting a history of IPAA, 199 (82%) reported a history of pouch symptoms. Patients with recent pouch symptoms demonstrated higher mean T-scores in pain interference (53.0 versus 45.3; P < 0.001), depression (51.0 versus 46.4; P = 0.002), and fatigue (56.3 versus 47.0; P < 0.001). Symptomatic pouch patients reported lower mean scores in social role satisfaction (47.4 versus 54.6) and short IBD questionnaire (4.8 versus 5.8) (both P < 0.001). These differences were all clinically meaningful.

CONCLUSIONS

In a large sample of patients with IBD, nearly all patients with IPAA reported a history of pouch symptoms. Patients experiencing symptoms within the 6 months before the survey assessment demonstrated clinically meaningful decrements in patient-reported outcomes in multiple domains of physical and psychosocial functioning.

Risk of Rectal Cancer After Colectomy for Patients With Ulcerative Colitis: A National Cohort Study

BACKGROUND & AIMS

Patients with ulcerative colitis (UC) have an increased risk of rectal cancer, therefore reconstruction with an ileal pouch-anal anastomosis (IPAA) generally is preferred to an ileorectal anastomosis (IRA) after subtotal colectomy. Similarly, completion proctectomy is recommended for patients with ileostomy and a diverted rectum, although this approach has been questioned because anti-inflammatory agents might reduce cancer risk. We performed a national cohort study in Sweden to assess the risk of rectal cancer in patients with UC who have an IRA, IPAA, or diverted rectum after subtotal colectomy.

METHODS

We collected data from the Swedish National Patient Register for a cohort of 5886 patients with UC who underwent subtotal colectomy with an IRA, IPAA, or diverted rectum from 1964 through 2010. Patients who developed rectal cancer were identified from the Swedish National Cancer Register. The risk of rectal cancer was compared between this cohort and the general population by standardized incidence ratio analysis.

RESULTS

Rectal cancer occurred in 20 of 1112 patients (1.8%) who received IRA, 1 of 1796 patients (0.06%) who received an IPAA, and 25 of 4358 patients (0.6%) with a diverted rectum. Standardized incidence ratios for rectal cancer were 8.7 in patients with an IRA, 0.4 in patients with an IPAA, and 3.8 in patients with a diverted rectum. Risk factors for rectal cancer were primary sclerosing cholangitis in patients with an IRA (hazard ratio, 6.12), and colonic severe dysplasia or cancer before subtotal colectomy in patients with a diverted rectum (hazard ratio, 3.67).

CONCLUSIONS

In an analysis of the Swedish National Patient Register, we found that the risk for rectal cancer after colectomy in patients with UC is low, in relative and absolute terms, after reconstruction with an IPAA. An IRA and diverted rectum are associated with an increased risk of rectal cancer, compared with the general population, but the absolute risk is low. Patients and their health care providers should consider these findings in making decisions to leave the rectum intact, perform completion proctectomy, or reconstruct the colon with an IRA or IPAA.

Management of ulcerative colitis in Taiwan: consensus guideline of the Taiwan Society of Inflammatory Bowel Disease

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Restorative Proctocolectomy in Elderly IBD Patients: A Multicentre Comparative Study on Safety and Efficacy

BACKGROUND AND AIMS

Restorative proctocolectomy in elderly inflammatory bowel disease [ IBD] patients is controversial and limited data are available on the outcomes of surgery. The aim of this study was to evaluate the safety, efficacy, and long-term results of ileal-pouch-anal anastomosis in elderly patients, in a multicentre survey from European referral centres.

METHODS

The International Pouch Database [IPD] combined 101 variables. Patients aged ≥ 65 years were matched on the basis of open versus laparoscopic surgery with a control group of consecutive younger unselected patients with a ratio of 1:2. Statistical analysis was performed using two-tailed t test, chi square and Fisher's exact tests, Kaplan-Meier function, and log-rank tests where appropriate.

RESULTS

In the IPD, 77 patients aged ≥ 65 years [Group A] and 154 control patients [Group B] were identified. Elderly patients had more comorbidities [p = 0.0001], longer disease duration [p = 0.001], less extensive disease [p = 0.006], more previous abdominal operations [p = 0.0006], surgery for cancer or dysplasia more frequently [p = 0.0001], fewer single-stage procedures [p = 0.03], more diversions after ileal pouch-anal anastomosis [IPAA] [p = 0.05], and a higher laparoscopic conversion rate [p = 0.04]. Postoperative complications and pouch failure were similar between the groups, but Group A had more Clavien-Dindo IV-V complications [p = 0.04], and longer length of stay [p = 0.007]. Laparoscopy was associated with a shorter duration of surgery [p = 0.0001], and length of stay [p = 0.0001], and the same complication rate as open surgery.

CONCLUSIONS

Restorative proctocolectomy can be performed in selected elderly patients, but there is a higher risk of postoperative complications and longer length of stay in this group. Laparoscopy is associated with shorter operating time and length of stay.

[Restorative proctocolectomy for ulcerative colitis : Long-term functional results and quality of life]

Restorative proctocolectomy with ileo-pouch-anal anastomosis is the standard procedure for ulcerative colitis. It provides complete removal of the diseased colorectum, avoids permanent ileostomy and allows the preservation of continence. Functional results and quality of life after restorative proctocolectomy are of great importance. Patients usually have 5-6 bowel movements per day, and continence is satisfactory in more than 90% of patients. A good pouch function strongly correlates with high quality of life. Postoperative septic complications are the main risk factor for bad pouch function and pouch failure; therefore nowadays most procedures are performed with a covering ileostomy. Quality of life is usually impaired by active ulcerative colitis, and restorative proctocolectomy improves the quality of life up to the level of a healthy reference population. Taken together, restorative proctocolectomy provides excellent results concerning function and quality of life.
