The clinical and functional outcome after restorative proctocolectomy. A prospective study in 100 patients

Controversies in IPAA for Ulcerative Colitis: A Systematic Review of Different Anastomotic Techniques

BACKGROUND

Available techniques for IPAA in ulcerative colitis include handsewn, double-stapled, and single-stapled anastomoses. There are controversies, indications, and different outcomes regarding these techniques.

OBJECTIVE

To describe technical details, indications, and outcomes of 3 specific types of anastomoses in restorative proctocolectomy.

DATA SOURCE

Systematic literature review for articles in the PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.

STUDY SELECTION

Studies describing outcomes of the 3 different types of anastomoses, during pouch surgery, in patients undergoing restorative proctocolectomy for ulcerative colitis.

INTERVENTION

IPAA technique.

MAIN OUTCOME MEASURES

Postoperative outcomes (anastomotic leaks, overall complication rates, and pouch function).

RESULTS

Twenty-one studies were initially included: 6 studies exclusively on single-stapled IPAA, 2 exclusively on double-stapled IPAA, 6 studies comparing single-stapled to double-stapled techniques, 6 comparing double-stapled to handsewn IPAA, and 1 comprising single-stapled to handsewn IPAA. Thirty-seven studies were added according to authors' discretion as complementary evidence. Between 1990 and 2015, most studies were related to double-stapled IPAA, either only analyzing the results of this technique or comparing it with the handsewn technique. Studies published after 2015 were mostly related to transanal approaches to proctectomy for IPAA, in which a single-stapled anastomosis was introduced instead of the double-stapled anastomosis, with some studies comparing both techniques.

LIMITATIONS

A low number of studies with handsewn IPAA technique and a large number of studies added at authors' discretion were the limitations of this strudy.

CONCLUSIONS

Handsewn IPAA should be considered if a mucosectomy is performed for dysplasia or cancer in the low rectum or, possibly, for re-do surgery. Double-stapled IPAA has been more widely adopted for its simplicity and for the advantage of preserving the anal transition zone, having lower complications, and having adequate pouch function. The single-stapled IPAA offers a more natural design, is feasible, and is associated with reasonable outcomes compared to double-stapled anastomosis. See video from symposium.

Functional outcomes after transanal ileal pouch-anal anastomosis for ulcerative colitis: narrative review of the current literature

The transanal approach to ileal pouch-anal anastomosis (Ta-IPAA) for ulcerative colitis was introduced in 2015 and has since been shown to be a safe and feasible technique, although the impact of this approach on patient function remains unclear. A systematic literature review was performed to identify studies exploring functional outcomes and quality of life after Ta-IPAA. Seven papers were identified, which all demonstrated satisfactory functional outcomes after Ta-IPAA as measured by tools such as Cleveland Global Quality of Life (CGQOL), Oresland Score (OS), Pouch Functional Score (PFS), and Inflammatory Bowel Disease Questionnaire (IBDQ). Many gaps in the literature were identified including paucity of follow-up data beyond the 1-year mark, lack of fertility and fecundity assessment as functional outcomes, and limited evaluation of objective physiologic anal sphincter function. The Ta-IPAA therefore shows promise for good functional results in the short-term, although further research will be required to evaluate the stability of function over time as the technique becomes increasingly integrated into modern surgical practice.

Patient Reported Outcome Assessments Used in the Evaluation of Patients after Ileal Pouch-Anal Anastomosis: A Systematic Review

BACKGROUND AND AIMS

There is a paucity of validated measures to evaluate how patients feel and function after restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis. We performed a systematic review to evaluate all published patient reported outcomes (PROs) to assess symptom burden, functional status, and quality of life (QoL) after IPAA.

METHODS

An electronic literature search on PubMed, Embase, and Web of Science was performed from inception through October 12, 2021. Eligible full texts were further characterized by the type of assessment as well as the individual domains assessed by questions in the PRO measure.

RESULTS

Among the 129 full texts analyzed, 51 specific PRO measures were utilized. In the evaluation of all PRO measures, 46% included an assessment of disease-specific QoL with 27% evaluating more general QoL, and 15% assessing symptoms related to pouch function. Among the studies using disease-specific instruments, the Cleveland Clinic Global Quality of Life (42%) and the Inflammatory Bowel Disease Questionnaire (21%) were the most commonly used PRO measures. PRO questions were mapped to individual domains using binning methodology, with the greatest number of questions from individual PRO measures mapped to the bowel function domain (122).

CONCLUSION

In our assessment of PRO measures among patients after IPAA, the studies and individual measures varied widely in both the patient populations being evaluated as well as outcomes and specific domains being assessed. A valid measure that assesses the range of outcomes after IPAA could standardize assessment and advance the study of patients after IPAA.

Colectomy reconstruction for ulcerative colitis in Sweden and England: a multicenter prospective comparison between ileorectal anastomosis and ileal pouch-anal anastomosis after colectomy in patients with ulcerative colitis. (CRUISE-study)

BACKGROUND

There are no prospective trials comparing the two main reconstructive options after colectomy for Ulcerative colitis, ileal pouch anal anastomosis and ileorectal anastomosis. An attempt on a randomized controlled trial has been made but after receiving standardized information patients insisted on choosing operation themselves.

METHODS

Adult Ulcerative colitis patients subjected to colectomy eligible for both ileal pouch anastomosis and ileorectal anastomosis are asked to participate and after receiving standardized information the get to choose reconstructive method. Patients declining reconstruction or not considered eligible for both methods will be followed as controls. The CRUISE study is a prospective, non-randomized, multi-center, open-label, controlled trial on satisfaction, QoL, function, and complications between ileal pouch anal anastomosis and ileorectal anastomosis.

DISCUSSION

Reconstruction after colectomy is a morbidity-associated as well as a resource-intensive activity with the sole purpose of enhancing function, QoL and patient satisfaction. The aim of this study is to provide the best possible information on the risks and benefits of each reconstructive treatment.

TRIAL REGISTRATION

Ileal reservoir-associated complications in ulcerative colitis versus familial adenomatous polyposis: Impact on patient quality of life

BACKGROUND

Proctocolectomy with ileal reservoir is the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis.

OBJECTIVES

To evaluate long-term postoperative complications (1994-2019) in patients operated for familial adenomatous polyposis (FAP) and ulcerative colitis (UC) and the degree of satisfaction with the procedure.

METHODS

Observational study based on the analysis of a retrospective database with prospective follow-up in 115 consecutive patients: 79 with UC and 36 with FAP. A total of 88 patients were followed up, 60 with UC and 28 with PFA.

RESULTS

48 males (54.4%) with a mean age of 44.8 ± 10.6 years were evaluated. Indications for surgery were intractable disease in 54 patients (47%), dysplasia/cancer in 43 (37%), severe bleeding in 4 (4%) and perforation in 3 (3%). A proctectomy and mucosectomy of the rectal stump was performed in 67 (76.1%), and a double stapling technique in 21. A protective ileostomy was performed in all patients with UC and FAP. No differences were found in early complications between the two groups. Late complications showed a higher rate of reservoritis in UC patients compared to FAP (44.9 vs. 14.3%, p = 0.001), with more refractory reservoritis in the UC group (13.3 vs. 0%, p = 0.04) with no differences in bowel obstruction, strictures, or anastomotic fistulas. Overall satisfaction and adaptation were considered good in 87% of UC patients and only 57% in the FAP group (p < 0.01).

CONCLUSIONS

Proctocolectomy with ileal reservoir has comparable morbidity and mortality, except for the higher rate of reservoritis in patients with a history of UC, despite this contingency there is a better quality of life and greater acceptance of surgery in UC patients than in FAP patients.

Functional outcomes of transanal versus transabdominal restorative proctectomy with ileal pouch-anal anastomosis in ulcerative colitis-a monocentric retrospective comparative study

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) ensures satisfactory gastro-intestinal function and quality of life (QoL) in patients with refractory ulcerative colitis (UC). The transanal approach to proctectomy and IPAA (Ta-IPAA) has been developed to address the technical shortfalls of the traditional transabdominal approach (Tabd-IPAA). Ta-IPAA has proven to be safe but there is lack of reported functional outcomes. Aim of this study is to compare functional outcomes and QoL after Ta- or Tabd-IPAA for UC.

METHODS

This is a retrospective study of consecutive UC patients who underwent IPAA between 2011 and 2017, operated according to a modified 2- or 3-stage approach. Close rectal dissection was performed in Ta-IPAA as opposed to total mesorectal excision in Tabd-IPAA. A propensity score weighting was performed. Functional outcomes were assessed using the pouch functional score (PFS) and the Öresland score (OS). The global quality of life scale (GQOL) was used for patients' perspective on QoL. Follow-up was scheduled at 1, 3, 6, and 12 months, postoperatively.

RESULTS

One hundred and eight patients were included: 38 patients had Ta-IPAA. At 12 months follow-up, mean OS and PFS were 4.6 (CI 3.2-6.0) vs 6.2 (CI 5.0-7.3), p = 0.025 and 6.1 (CI 3.5-8.8) vs 7.4 (CI 5.4-9.5), p = 0.32, for Ta and Tabd-IPAA, respectively. Mean GQOL for Ta-IPAA was 82.5 (CI 74.8-90.1) vs 75.5 (69.4-81.7) for Tabd-IPAA (p = 0.045).

CONCLUSIONS

At 12 months postoperatively, pouch function and QoL of Ta-IPAA are probably as good as those of Tabd-IPAA. Limitations include retrospectivity, differences in the surgical technique, and lack of validated scores for QoL.

Perfusion Visualization during Ileal J-Pouch Formation—A Proposal for the Standardization of Intraoperative Imaging with Indocyanine Green Near-Infrared Fluorescence and a Postoperative Follow-Up in IBD Surgery

Background: An anastomotic leak (AL) after a restorative proctocolectomy and an ileal J-pouch increases morbidity and the risk of pouch failure. Thus, a perfusion assessment during J-pouch formation is crucial. While indocyanine green near-infrared fluorescence (ICG-NIRF) has shown potential to reduce ALs, its suitability in a restorative proctocolectomy remains unclear. We aimed to develop a standardized approach for investigating ICG-NIRF and ALs in pouch surgery. Methods: Patients undergoing a restorative proctocolectomy with an ileal J-pouch for ulcerative colitis at an IBD-referral-center were included in a prospective study in which an AL within 30 postoperative days was the primary outcome. Intraoperatively, standardized perfusion visualization with ICG-NIRF was performed and video recorded for postoperative analysis at three time points. Quantitative clinical and technical variables (secondary outcome) were correlated with the primary outcome by descriptive analysis and logistic regression. A novel definition and grading of AL of the J-pouch was applied. A postoperative pouchoscopy was routinely performed to screen for AL. Results: Intraoperative ICG-NIRF-visualization and its postoperative visual analysis in 25 patients did not indicate an AL. The anastomotic site after pouch formation appeared completely fluorescent with a strong fluorescence signal (category 2) in all cases of ALs (4 of 25). Anastomotic site was not changed. ICG-NIRF visualization was reproducible and standardized. Logistic regression identified a two-stage approach vs. a three-stage approach (Odds ratio (OR) = 20.00, 95% confidence interval [CI] = 1.37–580.18, p = 0.029) as a risk factor for ALs. Conclusion: We present a standardized, comparable approach of ICG-NIRF visualization in pouch surgery. Our data indicate that the visual interpretation of ICG-NIRF alone may not detect ALs of the pouch in all cases—quantifiable, objective methods of interpretation may be required in the future.

Ileal pouch-anal anastomosis; 18 years of experience and outcomes across two generations of surgeons at a tertiary center in Sweden

AIM

Reconstructive surgery with ileal pouch-anal anastomosis (IPAA) is the standard procedure after colectomy in patients with Ulcerative Colitis (UC) and Familial Adenomatous Polyposis (FAP). It is of interest to understand how a generation shift of the surgeons performing IPAA has affected patients' outcomes.

METHOD

All consecutive patients who underwent IPAA in the period 1999-2016 at Sahlgrenska University Hospital/Östra, Gothenburg, Sweden, were included. Surgeons representing two different generations performed the surgeries during this period. The following 6-year time periods were assigned for surgeries performed by: experienced surgeons (1999-2004; Period 1); the new generation of surgeons undergoing training (2005-2010; Period 2); and the new generation of experienced surgeons (2011-2016; Period 3). The primary endpoint was post-operative complications (Clavien-Dindo ≥3b), and the secondary endpoints were the functional outcome, failure of the pouch, and mortality. Logistic analyses of the results were performed.

RESULTS

Overall, 281 patients were included in the study. The rate of post-operative severe complications was lower in Period 1 [Odds Ratio (OR) 0.137; p = .01]. There was no difference in functional outcome between the groups.

CONCLUSION

This study implicates that the risk of post-operative complications after IPAA is lower when the surgery is performed by a generation of more-experienced surgeons. This might support literature that concludes that surgical units that have a high throughput of patients and are staffed by surgeons who perform many procedures provide better outcomes.

Proctocolectomy and ileal pouch-anal anastomosis for the treatment of collagenous colitis

The role of surgery for collagenous colitis (CC) is unexplored. Either diverting stoma, subtotal colectomy with ileo-rectal anastomosis, and proctocolectomy with ileal pouch-anal anastomosis (IPAA) have been proposed. However, the optimal surgical strategy still needs to be defined. The aim of this short report is to report our experience with two cases of IPAA for CC. Two patients affected by histologically proven CC with watery diarrhea refractory to several lines of medical treatment underwent a laparoscopic proctocolectomy with IPAA at a tertiary referral hospital for the treatment of Inflammatory Bowel Disease in Belgium. A longer rectal cuff was left in place because of the absence of macroscopic inflammation of the rectal mucosa and the consequent negligible risk of cuffitis. No postoperative complications (90 days) occurred. Definitive pathological examination confirmed the diagnosis of CC. At six months, pouchoscopy revealed no signs of inflammation. One year after surgery, mean Öresland and Pouch Functional Score were 10.5 (8-13) and 11.5 (9-14). Functional outcomes after IPAA for CC were barely satisfactory. A high stool frequency not responding to high doses of anti-diarrheals was observed. This has also previously been reported for CC patients receiving a diverting stoma. Proctocolectomy and IPAA for medical refractory CC leads to acceptable short-term gastrointestinal functional outcomes which seems to be particularly affected by high stool frequency. For this reason, pouch surgery might not be the optimal indication for collagenous colitis.

Hyperspectral Imaging: A New Intraoperative Tool for Pouch Assessment in Patients Undergoing Restorative Proctocolectomy

Introduction

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a challenging operation. Especially the mobilization of the pouch into the pelvis can be complex. Adequate perfusion of the pouch is required for optimal healing and functioning.

Methods

With hyperspectral imaging (HSI) wavelengths between 500 and 1,000 nm can be analyzed in addition to visible light and by reflecting patterns. This intraoperative procedure is non-invasive, contact-free, and no contrast medium is needed. Fifteen patients undergoing IPAA were examined prospectively, and the pouch was evaluated by HSI intraoperatively. HSI was measured in standardized fashion at 4 defined locations of the J-pouch. Each measurement took about 10 s. The clinical postoperative course was assessed in all patients and correlated to the intraoperative HSI findings.

Results

Mean near-infrared perfusion and oxygenation of patients showed values ≥74% for all defined pouch areas, revealing good blood supply. Three minor anastomotic leaks were detected by standard pouchoscopy in the postoperative course, which could be treated conservatively with endosponge therapy.

Conclusion

HSI values of perfusion and oxygenation of the IPAA were high. The leak rate is associated with redo procedures. This is reflected by the current literature and most likely related to the higher complexity of the revisional pouch operation. HSI has proved itself as a quick and effective new intraoperative tool to evaluate pouch perfusion objectively and quantitatively.

Patients Undergoing Ileoanal Pouch Surgery Experience a Constellation of Symptoms and Consequences Representing a Unique Syndrome: A Report from the Patient-Reported Outcomes After Pouch Surgery (PROPS) Delphi Consensus Study

BACKGROUND

Functional outcomes after ileoanal pouch creation have been studied; however, there is great variability in how relevant outcomes are defined and reported. More importantly, the perspective of patients has not been represented in deciding which outcomes should be the focus of research.

OBJECTIVE

The primary aim was to create a patient-centered definition of core symptoms that should be included in future studies of pouch function.

DESIGN

This was a Delphi consensus study.

SETTING

Three rounds of surveys were used to select high-priority items. Survey voting was followed by a series of online patient consultation meetings used to clarify voting trends. A final online consensus meeting with representation from all 3 expert panels was held to finalize a consensus statement.

PATIENTS

Expert stakeholders were chosen to correlate with the clinical scenario of the multidisciplinary team that cares for pouch patients, including patients, colorectal surgeons, and gastroenterologists or other clinicians.

MAIN OUTCOME MEASURES

A consensus statement was the main outcome.

RESULTS

patients, 62 colorectal surgeons, and 48 gastroenterologists or nurse specialists completed all 3 Delphi rounds. Fifty-three patients participated in online focus groups. One hundred sixty-one stakeholders participated in the final consensus meeting. On conclusion of the consensus meeting, 7 bowel symptoms and 7 consequences of undergoing ileoanal pouch surgery were included in the final consensus statement.

LIMITATIONS

The study was limited by online recruitment bias.

CONCLUSIONS

This study is the first to identify key functional outcomes after pouch surgery with direct input from a large panel of ileoanal pouch patients. The inclusion of patients in all stages of the consensus process allowed for a true patient-centered approach in defining the core domains that should be focused on in future studies of pouch function.

Chronic Antibiotic-Refractory Pouchitis: Management Challenges

Background

Pouchitis is the most common long-term complication in patients with ulcerative colitis who underwent restorative proctocolectomy with ileal pouch-anal anastomosis. The incidence of acute pouchitis is 20% after 1 year and up to 40% after 5 years. Chronic antibiotic-refractory pouchitis develops in approximately 10% of patients.

Aim

To present a narrative review of published literature regarding the management of chronic antibiotic-refractory pouchitis.

Methods

Current relevant literature was summarized and critically evaluated.

Results

Clear definitions should be used to classify pouchitis into acute versus chronic, and responsive versus dependent versus refractory to antibiotics. Before treatment is started for chronic antibiotic-refractory pouchitis, secondary causes should be ruled out. There is a need for validated scoring systems to measure the severity of the disease. Because chronic antibiotic-refractory pouchitis is a rare condition, only small studies with often a poor study design have been performed. Treatments with antibiotics, aminosalicylates, steroids, immunomodulators and biologics have shown to be effective and safe for chronic antibiotic-refractory pouchitis. Also, treatments with AST-120, hyperbaric oxygen therapy, tacrolimus enemas, and granulocyte and monocyte apheresis suggested some efficacy.

Conclusion

The available data are weak but suggest that therapeutic options for chronic antibiotic-refractory pouchitis are similar to the treatment strategies for inflammatory bowel diseases. However, randomized controlled trials are warranted to further identify the best treatment options in this patient population.

The pouch behaving badly: management of morbidity after ileal pouch-anal anastomosis

AIM

Ileal pouch-anal anastomosis (IPAA), or a 'pouch', allows restoration of intestinal continuity after proctocolectomy for ulcerative colitis or familial adenomatous polyposis. Most patients have a good long-term outcome after IPAA, but in a significant proportion the functional outcome and quality of life are unsatisfactory. We term this outcome 'the pouch behaving badly'. Managing this, especially one is when unfamiliar with the possible underlying pathologies, is a challenge for both patient and clinician. We aim to outline the clinical approach to the pouch behaving badly, highlighting key aspects of investigation and management.

METHOD

This is a narrative review of the literature covering the investigation and management of postoperative complications and morbidity after IPAA.

RESULTS

Management of the pouch behaving badly requires a careful clinical assessment. The patient may present with multiple symptoms and a clear picture of the symptomatology and past history should be constructed before thorough examination and specialist investigation. We divide the pathology that underlies this clinical scenario into surgical, inflammatory, mechanical, functional and dysplastic causes and outline the investigation and management of each one.

CONCLUSION

The pouch behaving badly is a challenging problem for both patient and clinician. A detailed clinical assessment with careful specialist investigation is key to diagnosing the underlying pathology. We stress the importance of patient-centred care - the aim is to improve quality of life.

Surgical results and quality of life of patients submitted to restorative proctocolectomy and ileal pouch-anal anastomosis

PURPOSE

restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice in some cases of familial adenomatous polyposis (FAP) and ulcerative colitis (UC). IPAA allows complete removal of the diseased colon and rectum, however, it is associated with substantial morbidity and potential consequences to patients' quality of life (QoL).

AIMS

to evaluate the surgical results, functional outcomes and QoL after IPAA; and to examine the impact of surgical complications upon QoL.

METHODS

we reviewed the records of 55 patients after IPAA, with emphasis on surgical outcomes. Forty patients answered the questionnaires. The Cleveland Global Quality of Life (CGQL), Inflammatory Bowel Disease Questionnaire (IBDQ), and Short Form 36 Health Survey Questionnaire (SF36).

RESULTS

the average age was 42.1±14.1 years. 63.6% of the patients were male, and 69.1% had FAP. Operative mortality was 1.8% and overall morbidity was 76.4%. Anastomotic leakage was the most frequent early complication (34.5%). Pouchitis (10.8%) and small bowel obstruction (9.1%) were the most common late complications. Patients with UC had the most severe complications (p=0.014). Pelvic complications did not have a negative effect on functional outcomes or QoL scores. Female patients had decreased pouch evacuation frequency, fewer nocturnal bowel movements, decreased bowel symptom impact on QoL (p=0.012), and better CGQL (p=0.04). Patients with better education had better QoL scores, and patients who had their pouches for more than five years scored lower.

CONCLUSION

the high morbidity has no impact on function or QoL. Bowel function is generally acceptable. QoL is good and affected by sex, education and time interval since IPAA.

Patient-Reported Outcome Measures in Colon and Rectal Surgery: A Systematic Review and Quality Assessment

BACKGROUND

There is growing interest in using patient-reported outcome measures to support value-based care in colorectal surgery. To draw valid conclusions regarding patient-reported outcomes data, measures with robust measurement properties are required.

OBJECTIVE

The purpose of this study was to assess the use and quality of patient-reported outcome measures in colorectal surgery.

DATA SOURCES

Three major databases were searched for studies using patient-reported outcome measures in the context of colorectal surgery.

STUDY SELECTION

Articles that used patient-reported outcome measures as outcome for colorectal surgical intervention in a comparative effectiveness analysis were included. Exclusion criteria included articles older than 11 years, non-English language, age <18 years, fewer than 40 patients, case reports, review articles, and studies without comparison.

MAIN OUTCOME MEASURES

This was a quality assessment using a previously reported checklist of psychometric properties.

RESULTS

From 2007 to 2018, 368 studies were deemed to meet inclusion criteria. These studies used 165 distinct patient-reported outcome measures. Thirty were used 5 or more times and were selected for quality assessment. Overall, the measures were generally high quality, with 21 (70%) scoring ≥14 on an 18-point scale. Notable weaknesses included management of missing data (14%) and description of literacy level (0%).

LIMITATIONS

The study was limited by its use of original articles for quality assessment. Measures were selected for quality analysis based on frequency of use rather than other factors, such as impact of the article or number of patients in the study.

CONCLUSIONS

Patient-reported outcome measures are widely used in colorectal research. There was a wide range of measures available, and many were used only once. The most frequently used measures are generally high quality, but a majority lack details on how to deal with missing data and information on literacy levels. As the use of patient-reported outcome measures to assess colorectal surgical intervention increases, researchers and practitioners need to become more knowledgeable about the measures available and their quality.

Bowel Function After J-Pouch May Be More Complex Than Previously Appreciated: A Comprehensive Analysis to Highlight Existing Knowledge Gaps

BACKGROUND

Functional outcomes following J-pouch for ulcerative colitis have been studied, but lack standardization in which symptoms are reported. Furthermore, the selection of symptoms studied has not been patient centered.

OBJECTIVE

This study aimed to utilize a validated bowel function survey to determine which symptoms are present after J-pouch creation, and whether patients display a functional profile similar to low anterior resection syndrome.

DESIGN

This study is a retrospective analysis of a prospectively maintained single-center database.

SETTINGS

This study was conducted at the colorectal surgery center of a tertiary care academic hospital PATIENTS:: Included were 159 patients with J-pouch, ≥6 months after ileostomy reversal.

MAIN OUTCOME MEASURES

The primary outcomes were individual answers to the Memorial Sloan Kettering Cancer Center Bowel Function Instrument. The original Bowel Function Instrument validation cohort was used as an historical comparison (n = 127).

RESULTS

The mean total Bowel Function Instrument score for the J-pouch cohort was 59.9 ± 9.7 compared with a reported average score of 63.7 ± 11.6 for patients with low anterior resection in the validation cohort (p < 0.001), indicating worse bowel function in patients with J-pouch. When evaluating the Bowel Function Instrument subscales, patients with J-pouch reported frequency subscale scores of 18.2 ± 3.8, diet scores of 12.2 ± 3.8, and urgency scores of 15.9 ± 3.7, compared with 21.7 ± 4.5 (p < 0.001), 14.1 ± 3.7 (p < 0.001), and 15.0 ± 3.9 (p = 0.04) for patients undergoing rectal resection. Furthermore, 90.4% of patients with J-pouch state that they are sometimes, rarely, or never able to wait 15 minutes to get to the toilet. In addition, 56.4% of patients report having another bowel movement within 15 minutes of the last bowel movement, sometimes, always, or most of the time, and 50.6% of patients say that they sometimes, rarely, or never feel like their bowels have been totally emptied after a bowel movement.

LIMITATIONS

This study is limited because it took place at a single center and the Bowel Function Instrument was only validated for patients undergoing rectal resection.

CONCLUSIONS

Patients that undergo J-pouch surgery exhibit a constellation of bowel function symptoms that is more complex than fecal incontinence and frequency alone, despite the focus on these functional outcomes in the literature.

Anorectal Function After Ileo-Rectal Anastomosis Is Better than Pelvic Pouch in Selected Ulcerative Colitis Patients

BACKGROUND

With a lifelong perspective, 12% of ulcerative colitis patients will need a colectomy. Further reconstruction via ileo-rectal anastomosis or pouch can be affected by patients' perspective of their quality of life after surgery.

AIM

To assess the function and quality of life after restorative procedures with either ileo-rectal anastomosis or ileal pouch-anal anastomosis in relation to the inflammatory activity on endoscopy and in biopsies.

METHOD

A total of 143 UC patients operated with subtotal colectomy and ileo-rectal anastomosis or pouches between 1992 and 2006 at Linköping University Hospital were invited to participate. Those who completed the validated questionnaires (Öresland score, SF-36, Short Health Scale) were offered an endoscopic evaluation including multiple biopsies. Associations between anorectal function and quality of life with type of restorative procedure and severity of endoscopic and histopathologic grading of inflammation were evaluated.

RESULTS

Some 77 (53.9%) eligible patients completed questionnaires, of these 68 (88.3%) underwent endoscopic evaluation after a median follow-up of 12.5 (range 3.5-19.4) years after restorative procedure. Patients with ileo-rectal anastomosis reported better overall Öresland score: median = 3 (IQR 2-5) for ileo-rectal anastomosis (n = 38) and 10 (IQR 5-15) for pouch patients (n = 39) (p < 0.001). Anorectal function (Öresland score) and endoscopic findings (Baron-Ginsberg score) were positively correlated in pouch patients (tau: 0.28, p = 0.006).

CONCLUSION

Patients operated with ileo-rectal anastomosis reported better continence compared to pouches. Minor differences were noted regarding the quality of life. Ileo-rectal anastomosis is a valid option for properly selected ulcerative colitis patients if strict postoperative endoscopic surveillance is carried out.

Long-term functional outcome after restorative proctocolectomy: a cross-sectional study

OBJECTIVE

Restorative proctocolectomy is the procedure of choice in the surgical treatment of ulcerative colitis. Functional outcome is the key result of surgery. The aim of this study was to evaluate the long term-functional outcome after the procedure.

MATERIAL AND METHODS

The study comprised 282 ulcerative colitis patients over 18 years of age who underwent restorative proctocolectomy between1985 and 2009. The median follow-up time was 13 years (range 4-28). Functional outcome of the pouch was evaluated by the disease-specific Öresland questionnaire with a score 0-15; 15 being the worst, and score <8 considered well-functioning.

RESULTS

The mean functional score was 5.5 (men 5.6, women 5.0). Seventy per cent of the patients had a well-functioning pouch. Those with poor function had had significantly more pouchitis than the patients with well-functioning pouches, 51.0 vs. 25.6% respectively (p = .001). No association was found between functional score and the time since the operation. In multiple regression analysis only the occurrence of pouchitis was associated with poor functional results.

CONCLUSIONS

The functional results were good and remained stable in the majority of the patients. Pouchitis seemed to have a negative impact on the functional results. Elderly patients especially need careful planning and counselling before restorative proctocolectomy.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

A systematic review and meta-analysis comparing adverse events and functional outcomes of different pouch designs after restorative proctocolectomy

AIM

There is no consensus as to which ileoanal pouch design provides better outcomes after restorative proctocolectomy. This study compares different pouch designs.

METHOD

A systematic review of the literature was performed. A random effects meta-analytical model was used to compare adverse events and functional outcome.

RESULTS

Thirty comparative studies comparing J, W, S and K pouch designs were included. No significant differences were identified between the different pouch designs with regard to anastomotic dehiscence, anastomotic stricture, pelvic sepsis, wound infection, pouch fistula, pouch ischaemia, perioperative haemorrhage, small bowel obstruction, pouchitis and sexual dysfunction. The W and K designs resulted in fewer cases of pouch failure compared with the J and S designs. J pouch construction resulted in a smaller maximum pouch volume compared with W and K pouches. Stool frequency per 24 h and during daytime was higher following a J pouch than W, S or K constructions. The J design resulted in increased faecal urgency and seepage during daytime compared with the K design. The use of protective pads during daytime and night-time was greater with a J pouch compared to S or K. The use of antidiarrhoeal medication was greater after a J reservoir than a W reservoir. Difficulty in pouch evacuation requiring intubation was higher with an S pouch than with W or J pouches.

CONCLUSION

Despite its ease of construction and comparable complication rates, the J pouch is associated with higher pouch failure rates and worse function. Patient characteristics, technical factors and surgical expertise should be considered when choosing pouch design.

Health-Related Quality of Life after Restorative Proctocolectomy: A Cross-Sectional Study

BACKGROUND AND AIMS:

Patients undergoing restorative proctocolectomy have often suffered from active ulcerative colitis which should be remembered when assessing quality of life after operation. The aim of this study was to explore health-related quality of life after restorative proctocolectomy in those with poor or good pouch function and to compare that to patients with active or inactive ulcerative colitis and to the general population.

MATERIAL AND METHODS:

Altogether, 282 restorative proctocolectomy patients were investigated. The control group comprised 408 ulcerative colitis patients from the local register. Generic 15D and disease-specific inflammatory bowel disease questionnaire health-related quality of life instruments were used. Population-based data were available for 15D. Pouch function was evaluated with Öresland score and colitis activity with simple clinical colitis activity index.

RESULTS:

15D results showed that patients with good pouch function had health-related quality of life similar to that of the general population. Health-related quality of life with inflammatory bowel disease questionnaire was equally good in patients with good pouch function (n = 131; 70%) and inactive colitis (n = 95; 63%), and equally impaired in patients with poor pouch function (n = 56; 30%) and active colitis (n = 18; 12%).

CONCLUSION:

The majority of patients had health-related quality of life comparable to that in general population. Most patients with active ulcerative colitis are likely to improve their health-related quality of life after successful surgery. These findings are important when informing colitis patients about life after surgery.

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.

Small Bowel Obstruction After Ileal Pouch-Anal Anastomosis With a Loop Ileostomy in Patients With Ulcerative Colitis

Purpose

Small bowel obstruction (SBO) remains a common complication after pelvic or abdominal surgery. However, the risk factors for SBO in ulcerative colitis (UC) surgery are not well known. The aim of the present study was to clarify the risk factors associated with SBO after ileal pouch-anal anastomosis (IPAA) with a loop ileostomy for patients with UC.

Methods

The medical records of 96 patients who underwent IPAA for UC between 1999 and 2011 were reviewed. SBO was confirmed based on the presence of clinical symptoms and radiographic findings. The patients were divided into 2 groups: the SBO group and the non-SBO group. We also analyzed the relationship between SBO and computed tomography (CT) scan image parameters.

Results

The study included 49 male and 47 female patients. The median age was 35.5 years (range, 14–72 years). We performed a 2- or 3-stage procedure as a total proctocolectomy and IPAA for patients with UC. SBO in the pretakedown of the loop ileostomy after IPAA occurred in 22 patients (22.9%). Moreover, surgical intervention for SBO was required for 11 patients. In brief, closure of the loop ileostomy was performed earlier than expected. A multivariate logistic regression analysis revealed that the 2-stage procedure (odds ratio, 2.850; 95% confidence interval, 1.009–8.044; P = 0.048) was a significant independent risk factor associated with SBO. CT scan image parameters were not significant risk factors of SBO.

Conclusion

The present study suggests that a 2-stage procedure is a significant risk factor associated with SBO after IPAA in patients with UC.

Management of Pouchitis and Other Common Complications of the Pouch

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the preferred surgical treatment for refractory or complicated ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Pouchitis is the most common complication of this procedure and can occur in about 50% of patients. Treatment of pouchitis depends on the phenotype of disease. Pouchitis can be classified as acute, chronic/refractory, or secondary pouchitis, which includes pouchitis occurring due to Crohn's disease (CD). CD of the pouch is becoming an increasingly recognized problem, and management is challenging. This article reviews the literature and offers treatment recommendations regarding management of pouchitis and CD of the pouch.

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.

Risk of Rectal Neoplasia after Colectomy and Ileorectal Anastomosis for Ulcerative Colitis

BACKGROUND AND AIMS

Colectomy can be required in the management of ulcerative colitis [UC]. While ileal-pouch anal anastomosis [IPAA] is the recommended reconstruction technique, ileorectal anastomosis [IRA] is still performed and might present some advantages. However, the risk of rectal neoplasia might limit its indication. The aims of our study were to determine the incidence of rectal neoplasias following IRA for UC and to identify risk factors associated with rectal carcinomas.

METHODS

We performed a multicenter retrospective study including patients who underwent IRA for UC from 1960 to 2014 in 13 centers. Cox-proportional hazard models were used to determine carcinoma-associated risk factors.

RESULTS

A total of 343 patients were included, with a median follow-up of 10.4 years after IRA. At the end of follow-up, 38 rectal neoplasias (including 19 carcinomas) were diagnosed, and 7 patients [2%] had either died from rectal carcinoma or had a metastatic disease. Incidences of rectal carcinoma after IRA for UC were estimated at 3.2% at 10 years and at 7.3% at 20 years, whereas incidences of neoplasia were estimated at 7.1% and 14% at 10 and 20 years, respectively. In multivariate analysis, age at IRA, IBD duration, primary sclerosing cholangitis [PSC] and history of prior colonic carcinoma were independently associated with the risk of rectal carcinoma following IRA.

CONCLUSION

The risk of rectal carcinoma in patients with IRA for UC remains, and this justifies long-term endoscopic surveillance. Either IPAA or end ileostomy should be considered in 'high-risk' patients i.e. those with PSC and/or with prior colonic neoplasia.

[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.

[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.

Restorative proctocolectomy with two different pouch designs: few complications with good function

AIM

The object of this study was to compare function and quality of life after restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) surgery having two different pouch designs.

METHOD

Patients having RPC in an academic unit from 2000 who had had the loop-ileostomy closed by June 2013 were identified from the hospital medical records. They were sent a questionnaire regarding quality of life and interviewed using a pouch function score (PFS) described by Oresland (score 0-16, higher scores denote worse function).

RESULTS

One hundred and three patients underwent surgery, of whom 56 had a J-pouch design and 47 a K-pouch design, this being a double-folded Kock pouch without the nipple valve. No patients have had the pouch removed or defunctioned due to failure at a mean of 8 years. The reoperation rate was 11.6%. The mean PFS was 5.43 and 5.27 for J- and K-pouches, respectively (P = 0.766). More patients with a J-pouch reported a social handicap due to poor bowel function (P = 0.041). Patients with a PFS ≥ 8 had a poorer quality of life. A score of ≥ 8 was reported by 16% of K-pouch and 25% of J-pouch patients (P = 0.29).

CONCLUSION

RPC is a safe procedure with a low complication rate and good functional outcome. Small improvements in function have an impact on a patient's quality of life. Although the J-pouch is the most commonly used, the K-pouch has some advantages. Other pouch designs deserve further evaluation.

Effect of probiotics (Lactobacillus plantarum 299 plus Bifidobacterium Cure21) in patients with poor ileal pouch function: a randomised controlled trial

OBJECTIVE

Poor pouch function after restorative proctocolectomy for ulcerative colitis is a considerable problem. Pouchitis and functional disorders are the most common reasons. Probiotics seem to have a beneficial effect in pouchitis but have not been assessed in functional pouch disorders. The aim was to analyse the effects of probiotics in patients with poor pouch function.

METHODS

Thirty-three patients were randomized to probiotics (Lactobacillus plantarum 299 and Bifidobacterium infantis Cure 21) or placebo in a double blinded, 1:1 fashion. The treatment effect was assessed by the pouch functional score (PFS; 0-15, 15 worst), pouchitis disease activity index (PDAI; 0-18, 18 worst), and levels of four faecal biomarkers of inflammation (calprotectin, lactoferrin, myeloperoxidase [MPO] and eosinophilic cationic protein [ECP]).

RESULTS

Thirty-two patients were included (probiotics = 17, placebo = 16). There was no difference in change in the PFS from before to after treatment between the groups (median difference: -1.00, 95% C.I. -3.00 to 0.00, p = 0.119). Furthermore, probiotics had no effect on PDAI (median difference: 0.00, 95% C.I. 0.00-1.00, p = 0.786), or on faecal biomarkers. Significant correlations were observed between PDAI and each of the faecal biomarkers at study start. There were no correlations between PFS or PDAI symptom subscore and the biomarkers. PDAI endoscopic and histologic subscores correlated significantly to each of the biomarkers.

CONCLUSION

The hypothesis that probiotics improves pouch-related dysfunction was not confirmed. Faecal biomarkers could play a future role in the management of pouch patients.

Correlation between pouch function and sexual function in patients with IPAA

OBJECTIVE

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for ulcerative colitis refractory to medical treatment and familial adenomatous polyposis. The objective of this study was to study the impact of postoperative pouch function on sexual function. Sexual function after IPAA surgery has also been compared to sexual function in the average Norwegian population.

MATERIAL AND METHODS

All patients having undergone IPAA from 2000 to June 2013 were identified from the hospital medical record files and sent validated questionnaires regarding their sexual function. Pouch function was scored according to Oresland score through a phone interview. Patients operated on or before June 2012 were asked to answer the same questionnaires twice with an interval of one year to see how stable sexual function is over time.

RESULTS

Sixty-eight out of 100 consecutive patients answered the questionnaire regarding both sexual function and pouch function (44 men, 24 women). There was no significant relationship between pouch and sexual function in men (p-value 0.158, corr. coefficient - 0.216). In women there was a significant relationship (p-value - 0.01, corr. coefficient 0.517). There was no significant shift in sexual function during the study period.

CONCLUSION

We found no significant correlation between sexual function and pouch function in men. In women, we found a significant correlation between poor pouch function and impaired sexual function. As similar studies have found, sexual function remains good after IPAA surgery. This is an important information for patients and physicians, both to inform patients correctly prior to surgery, and in the postoperative follow-up.

Scintigraphic Small Intestinal Transit Time and Defaecography in Patients with J-Pouch

Objective methods for examination of pouch function are warranted for a better understanding of the functional result and treatment of dysfunction. The objective of this study was to evaluate the results of scintigraphic intestinal transit time and defaecography compared to the results of pouch function, mucosal condition and a questionnaire on quality of life (QoL). This cross-sectional study included 21 patients. Scintigraphic transit time and defaecography was determined with the use of Tc-99m. Pouch function was assessed by number of bowel movements, pouch volume, and continence. Pouch mucosal condition was evaluated by endoscopy and histology. Median transit time was 189 min (105-365). Median ejection fraction at defaecography (EF) was 49% (3-77) and 62% (17-98) after first and second defecation. Median pouch volume was 223 mL (100-360). A median daily stool frequency of nine (4-25) was reported and three (14%) patients suffered from daytime incontinence. No patients had symptomatic or endoscopic pouchitis; however, the histology showed unspecific inflammation in 19 (90%) patients. There was no correlation between transit time, evacuation fraction (EF) and pouch function in univariate analysis. However, we found a high body mass index (BMI) and a low bowel movement frequency to be associated with a longer transit time by multivariate analysis. Scintigraphic determination of transit time and defaecography are feasible methods in patients with ileal pouch anal anastomosis, but the clinical relevance is yet doubtful.

A reappraisal of the ileo-rectal anastomosis in ulcerative colitis

Colectomy is still frequently required in the care of ulcerative colitis. The most common indications are either non-responding colitis in the emergency setting, chronic active disease, steroid-dependent disease or neoplastic change like dysplasia or cancer. The use of the ileal pouch anal anastomosis has internationally been the gold standard, substituting the rectum with a pouch. Recently the use of the ileorectal anastomosis has increased in frequency as reconstructive method after subtotal colectomy. Data from centres using ileorectal anastomosis have shown the method to be safe, with functionality and risk of failure comparable to the ileal pouch anal anastomosis. The methods have different advantages as well as disadvantages, depending on a number of patient factors and where in life the patient is at time of reconstruction. The ileorectal anastomosis could, together with the Kock continent ileostomy, in selected cases be a complement to the ileal pouch anal anastomosis in ulcerative colitis and should be discussed with the patient before deciding on reconstructive method.

Sexual dysfunction in inflammatory bowel disease

Sexual health is a broad term that encompasses a variety of functions including sexual thoughts, desire, arousal, intercourse, orgasm, and the impact of body image. Sexual dysfunction in individuals with inflammatory bowel disease is multifactorial including the impact of psychosocial factors, disease activity, medical therapies, surgical interventions, body image perceptions and changes, hypogonadism, and pelvic floor disorders. Providers caring for patients with inflammatory bowel disease should be cognizant of these concerns and develop management plans and techniques for earlier diagnosis and treatment.

Surgery in the age of biological treatment

Surgery for IBD is in constant evolution; it does not appear that the introduction of biologicals has had a major effect on the chance of a patient being operated on or not. Pouch surgery had its heydays in the 80s and 90s and has since then become less frequent, but the number of patients undergoing surgery still seem about the same from one year to the other. Likewise, there is no substantial evidence that surgery for Crohn's disease is diminishing. There have been fears that patients on biological treatment have an increased risk of postoperative complications. The issue is not completely settled but it is likely that patients on biological treatment who come to surgery are those who do not benefit from biologicals. Thus, they are compromised in that they have an ongoing inflammation, are in bad nutritional state, and might have several other known risk factors for a complicated postoperative course. These factors and perhaps not the biologicals per se is what surgeons should consider. During the recent years, we have seen several new developments in IBD surgery; the ileorectal anastomosis is being used for ulcerative colitis and laparoscopic surgery usually resulting in a shorter hospital stay, less pain, and better cosmetics. We have also seen the introduction of robotic surgery, single incision minimal invasive surgery, transanal minimal invasive surgery, and other approaches to minimize surgical trauma. Time will show which of these innovations patients will benefit from.

Long-term functional outcome after ileal pouch anal anastomosis in 191 patients with ulcerative colitis

BACKGROUND

A long-lasting good functional outcome of the pelvic pouch and a subsequent satisfying quality of life (QoL) are mandatory. Long-term functional outcome and QoL in a single-center cohort were assessed.

PATIENTS AND METHODS

A questionnaire was sent to all patients with an IPAA for UC, operated between 1990 and 2010 in our department. Pouch function was assessed using the Öresland Score (OS) and the 'Pouch Functional Score' (PFS). QoL was assessed using a Visual Analogue Score (VAS).

RESULTS

250 patients (42% females) with a median age at surgery of 38 years (interquartile range (IQR): 29-48 years) underwent restorative proctocolectomy. Median follow-up was 11 years (IQR: 6-17 years). Response rate was 81% (n=191). Overall pouch function was satisfactory with a median OS of 6/15 (IQR: 4-8) and a median PFS of 6/30 (IQR: 3-11). 24-hour bowel movement is limited to 8 times in 68% of patients (n=129), while 55 patients (29%) had less than 6 bowel movements. 12 patients (6.5%) were regularly incontinent for stools, while 154 patients (82%) reported a good fecal continence. Fecal incontinence during nighttime was more common (n=72, 39%). Pouch function had little impact on social activity (4/10; IQR: 2-6) and on professional activity (3/10; IQR: 1-6). 172 patients (90%) reported to experience an overall better health condition since their operation. The OS and the PFS correlated well (Pearson's correlation coefficient=0.83). Overall pouch function was stable over time.

CONCLUSION

Majority of patients report a good pouch function on the long-term with limited impact on QoL.

Outcomes after ileal pouch anal anastomosis in patients with primary sclerosing cholangitis

BACKGROUND AND AIMS

Outcomes after ileal pouch anal anastomosis (IPAA) are not well established in patients with primary sclerosing cholangitis (PSC). We conducted a comprehensive outcomes assessment in these patients.

METHODS

A retrospective case note review of complications in all PSC-IPAA (n=21) and matched ulcerative colitis patients with IPAA (UC-IPAA; n=79) after surgery in Oxford (1983-2012) was conducted, and functional outcomes (Öresland score) were evaluated (2012). Quality of life [Cleveland Global Quality of Life Questionnaire, Short Form-36 (SF-36)], and sexual function were also assessed (2012) including patients with PSC-associated UC without IPAA (PSC-UC; n=19). Sub-group analysis of patients with large duct (ld) PSC-IPAA (n=17) was also performed.

RESULTS

The 1-, 5-, 10- and 20-year risk of acute pouchitis for PSC-IPAA was 10%, 19%, 31% and 65% respectively, compared to 3%, 10%, 14% and 28% in UC-IPAA (p=0.03). More PSC-IPAA (36%) had poor nocturnal pouch function (vs 2% in UC-IPAA; p=0.0016). There were no differences in surgical complications, quality of life or sexual function between the 3 main groups. LdPSC-IPAA had poorer pouch function (Öresland score: 7.7 vs 5.4 in UC-IPAA; p=0.02), and worse quality of life [SF-36 Physical: 42 vs 50.5 in UC-IPAA; 47.7 in PSC-UC; p=0.03 and Mental Health summary scores: 41.6 vs 51.2 in UC-IPAA; 42.3 in PSC-UC; p=0.04].

CONCLUSIONS

PSC-IPAA suffer more acute pouchitis and have worse functional outcomes than UC-IPAA. LdPSC-IPAA also have poorer quality of life.

Colectomy for patients with ulcerative colitis and primary sclerosing cholangitis - what next?

BACKGROUND AND AIMS

Primary sclerosing cholangitis (PSC) occurs in 2%-8% of patients who suffer from ulcerative colitis (UC). For patients who require colectomy, ileal pouch-anal anastomosis (IPAA) or ileorectal anastomosis (IRA) is employed to preserve continence.We evaluated the outcomes after IPAA and IRA for patients with UC-PSC, using patients with UC but without PSC as controls (UC-only group).

PATIENTS

In a case-control study conducted at Sahlgrenska University Hospital, Sweden, patients with UC-PSC (N=48; 31 IPAA and 17 IRA) were compared to patients with UC only (N=113; 62 IPAA and 51 IRA). Functional outcomes (Öresland score), pouchitis, surgical complications, and failure were evaluated.

RESULTS

For patients with IPAA, the median Öresland scores were similar for the two groups: 5 (range, 0-13) for the UC-PSC group and 5 for the UC-only group (range, 0-12; p>0.05). However, the IRA scores were significantly different at 7 (range, 2-11) and 3 (range, 0-11) for the respective groups (p=0.005). Pouchitis was more frequent in patients with UC-PSC. Complication rates did not differ. For patients with IPAA, the failure rate was 16% for those in the UC-PSC group versus 6% for those in the UC-only group (p>0.05); the corresponding results for IRA were 53% versus 22% (p=0.03).

CONCLUSIONS

For cases of IPAA, pouchitis seems to be more common in patients with UC-PSC. However, the functional outcomes and failure rates are unaffected by concurrent PSC. For patients with UC-PSC, functional outcome is poor and the failure rate is high after IRA.

Restorative proctocolectomy for ulcerative colitis: development and validation of a new scoring system for pouch dysfunction and quality of life

AIM

The purpose of this study was to develop and validate a pouch dysfunction score that could identify the aspects of function which have the greatest impact on quality of life as perceived by the patient.

METHOD

All (n = 1757) patients having restorative proctocolectomy in Denmark between 1980 and 2010 were identified. Of these, 1229 were available for study and were sent a questionnaire on bowel function and quality of life (QoL) designed specifically for this study. Function was correlated with QoL in a multivariate model using ordinal logistic regression with QoL as a dependent variable. The pouch dysfunction score was developed from a randomly selected half of the study population and the validity was tested on the other half.

RESULTS

1047 (85%) patients returned the questionnaire. On multivariate analysis, the symptom domains of 'incomplete emptying', 'severity of urgency', 'number of bowel movements/24 h', 'major incontinence' and 'use of anti-diarrhoeal medication' were associated with reduced QoL. The score was divided into three categories including 'none', 'minor' and 'some/major' pouch dysfunction. The corresponding coefficients gave the score a range from 0 to 7.5. There was a highly significant difference (P < 0.001) in score between the categories. The area under the receiver operating curve was 0.81.

CONCLUSION

Urgency, incomplete emptying, number of bowel movements/24 h, major incontinence and use of anti-diarrhoeal medication have a major impact on QoL. There was a high accuracy for the score, demonstrating its potential clinical usefulness in relating symptoms to QoL.

Ileal pouch anal anastomosis with modified double-stapled mucosectomy-the experience in China

AIM: To investigate the feasibility and long-term functional outcome of ileal pouch-anal anastomosis with modified double-stapled mucosectomy.

METHODS: From January 2002 to March 2011, fourty-five patients underwent ileal pouch anal anastomosis with modified double-stapled mucosectomy technique and the clinical data obtained for these patients were reviewed.

RESULTS: Patients with ulcerative colitis (n = 29) and familial adenomatous polyposis (n = 16) underwent ileal pouch-anal anastomosis with modified double-stapled mucosectomy. Twenty-eight patients underwent one-stage restorative proctocolectomy, ileal pouch anal anastomosis, protective ileostomy and the ileostomy was closed 4-12 mo postoperatively. Two-stage procedures were performed in seventeen urgent patients, proctectomy and ileal pouch anal anastomosis were completed after previous colectomy with ileostomy. Morbidity within the first 30 d of surgery occurred in 10 (22.2%) patients, all of them could be treated conservatively. During the median follow-up of 65 mo, mild to moderate anastomotic narrowing was occurred in 4 patients, one patient developed persistent anastomotic stricture and need surgical intervention. Thirty-five percent of patients developed at least 1 episode of pouchitis. There was no incontinence in our patients, the median functional Oresland score was 6, 3 and 2 after 1 year, 2.5 years and 5 years respectively. Nearly half patients (44.4%) reported “moderate functioning”, 37.7% reported “good functioning”, whereas in 17.7% of patients “poor functioning” was observed after 1 year. Five years later, 79.2% of patients with good function, 16.7% with moderate function, only 4.2% of patients with poor function.

CONCLUSION: The results of ileal pouch anal anastomosis with modified double-stapled mucosectomy technique are promising, with a low complication rate and good long-term functional results.

Evaluation of preoperative predictors of development of pouchitis after ileal-pouch-anastomosis in ulcerative colitis

INTRODUCTION

In this retrospective study, we aimed to evaluate preoperative predictive risk factors for development of pouchitis in the ulcerative colitis (UC) patients with ileal pouch-anal anastomosis (IPAA).

METHODS

The records of UC patients who underwent IPAA surgery and were under follow-up in the inflammatory bowel disease (IBD) clinic of our hospital between January 1994 and September 2009 were retrieved. Preoperative clinical, biochemical, and endoscopic findings, as well as preoperative endoscopic activity index (EAI), preoperative disease activity index (DAI) and operative characteristics were recorded. Patients with endoscopic, histological and clinical findings consistent with pouchitis were identified.

RESULTS

Out of a total of 49 patients who underwent IPAA for UC, pouchitis was identified in 20 (40.8%) of them. Overall, 37 (75.5%) patients had chronic active disease, eight (16.3%) patients had chronic intermittent disease with frequent relapses, and four (8.2%) patients had fulminant colitis prior to surgery. There was a statistically significant difference (P=0.02) among these patients for the development of pouchitis in postoperative period. The mean EAI (10.1 vs. 8.7, P=0.02) and DAI (10.0 vs. 8.6, P<0.01) in patients with pouchitis were significantly higher than that of patients who did not develop pouchitis. Multivariate analysis revealed steroid dependency (P=0.02), and a higher DAI (P=0.02) to be independent risk factors for the development of pouchitis.

CONCLUSION

A more severe preoperative clinical course and steroid dependency, as well as higher endoscopic and disease activity scores may be useful as preoperative predictors of subsequent pouchitis in UC patients undergoing IPAA surgery.

Study of sexual, urinary, and fecal function in females following restorative proctocolectomy

BACKGROUND

The aim was to investigate quality of life, sexual, fecal, and urinary function in females undergoing restorative proctocolectomy (RPC).

METHODS

A prospective case-control study was performed in two tertiary centers. Controls were females with ulcerative colitis, without a stoma or RPC. Validated questionnaires (SF-36, Female sexual function index, King's questionnaire, and the Wexner scale) were administered in the outpatient setting. Pearson chi(2), t-test, and Mann-Whitney U-tests were used to assess significance.

RESULTS

A total of 255 females were identified and 49% (n = 124) recruited. In all, 109 patients fulfilled the inclusion criteria: 55 (50.5%) inflammatory bowel disease (IBD); 54 (49.5%) RPC. The mean age of RPC patients was 41.8 years (± 12.7 SD) vs. 43.8 years (± 15.8) for IBD (P = 0.491). RPC females with urinary symptoms (urgency, frequency, or incontinence) were 10 years younger than IBD (RPC mean age 37.6 ± 7.3 years vs. IBD 47.4 ± 13.5; P = 0.044). Urgency in fecal function was experienced by more IBD patients (IBD 75.0% vs. RPC 47.9%; P = 0.006), although RPC patients had increased day (P < 0.001) and night bowel frequency (P < 0.001) and were more likely to experience night seepage (P = 0.001). RPC females who had a vaginal delivery (VD) were more likely to have day seepage (P = 0.046) and require pads (P = 0.026) than RPC females who had not undergone VD. There was no significant difference in sexual function.

CONCLUSIONS

RPC may adversely impact urinary function in female patients over time. Bowel frequency, seepage, and pad usage are increased following RPC and function may be worse following VD. RPC does not adversely affect overall sexual function.

Timing of restorative proctocolectomy in patients with medically refractory ulcerative colitis: the patient's point of view

BACKGROUND

Development of biologic agents has led to new therapeutic options for patients with refractory ulcerative colitis, and intensive medical therapy allows delay of restorative colectomy. However, the overall rate of colectomies has not changed. The decision as to timing of the operation is difficult.

OBJECTIVE

Our aim was to elucidate the patients' views about the timing of their own proctocolectomy.

DESIGN

This was a retrospective review of a prospectively designed database combined with a follow-up survey questionnaire.

SETTINGS AND PARTICIPANTS

We included patients who underwent proctocolectomy and ileal pouch-anal anastomosis for refractory ulcerative colitis from 1999 through 2009 at our university hospital.

MAIN OUTCOME MEASURES

A questionnaire was sent to patients asking whether they would have preferred to have had the operation performed earlier, later, or at the same time as it was actually done and to give the number of years or months earlier or later that they would have preferred. They were also asked to give reasons for their preference. Patients who preferred an earlier operation were compared with those satisfied with the timing regarding measures of postoperative quality of life and pouch function collected from the institution's prospective database.

RESULTS

Of 84 eligible patients, 70 (83%) responded. Of these, 37 (53%) would have preferred an earlier operation; 33 patients (47%) were satisfied with the timing. No patient would have chosen a later operation. Patients who preferred an earlier operation wished it to have been a median of 2 years earlier (range, 2-120 months). The main reasons for a preferred earlier time point were postoperative improvement of stool regulation in 89% (33/37), reduction of bleedings in 84% (31/37), and relief of pain in 68% (25/37). No significant differences were observed between groups regarding postoperative quality of life or pouch function.

LIMITATIONS

Limitations of the study included lack of validation and a nonsymmetrical structure of the questionnaire.

CONCLUSIONS

About half of the patients of our study would have preferred to have had proctocolectomy earlier than it had been performed, mainly because of the relief of symptoms that they experienced after the operation. For patients with an emerging refractory course of ulcerative colitis, earlier restorative proctocolectomy should be considered as an alternative to further intensified medical treatment.

A comprehensive review of inflammatory bowel disease focusing on surgical management

The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.

Quality of life after restorative proctocolectomy and ileal pouch-anal anastomosis in patients with familial adenomatous polyposis: a matter of adjustment

AIM

Favourable outcomes for health-related quality of life (HRQL) have been reported in patients with familial adenomatous polyposis (FAP) after restorative proctocolectomy and ileal pouch-anal anastomosis (RPC). However, less is known about patients' subjective experience and adjustment to postoperative impairment. Using a multidimensional psychometric assessment, we investigated patient-reported HRQL to determine the impact of the patient's subjective experience together with medical, functional and psychosocial factors on HRQL.

METHOD

In this cross-sectional study, 116 FAP patients who had undergone RPC on average 8 years earlier completed standardized and study-specific questionnaires and participated in a personal interview. The impact of medical, functional and psychosocial factors on patients' HRQL was determined by regression analyses.

RESULTS

When using a generic psychometric measure, FAP patients' overall HRQL was comparable with that of the general population. Impaired HRQL, however, was found in patients reporting poor pouch function in contrast to those reporting good or moderate functional outcome. Findings from a personalized interview also suggested that a good functional result does not necessarily translate into good HRQL. Personal resources predicted patients' physical and psychological well-being, whereas little variance of HRQL was explained by medical factors and function.

CONCLUSION

Patients' HRQL is, to a substantial degree, the result of adjustment to the adverse impact of RPC. By using personal resources the majority of patients may achieve satisfactory HRQL levels even when bowel function is impaired. A multidimensional assessment that comprises medical, functional and psychosocial aspects is required to ascertain an adequate evaluation of FAP patients after RPC.
