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.

Review article: the impact of diet on ileoanal pouch function and on the pathogenesis of pouchitis.

BACKGROUND: There is expanding interest in the role that diet plays in ileoanal pouch function and in the pathogenesis of pouchitis. AIMS: To present a narrative review of published literature regarding the relationship of diet with pouch function and the pathogenesis of pouchitis, and to provide potentially beneficial dietary strategies. METHODS: Current relevant literature was summarised and critically examined. RESULTS: Dietary components influence pouch function via their effect on upper gastrointestinal transit, small bowel water content and the structure and fermentative activity of the pouch microbiota. FODMAPs in fruits and vegetables appear to affect pouch function the most, with intake positively associated with increased stool frequency and reduced consistency. Dietary factors that influence the pathogenesis of pouchitis appear different and, at times, opposite to those better for optimising function. For example, risk of pouchitis appears to be inversely associated with intake of fruits. The food components mechanistically responsible for this observation are not known, but a rich supply of fermentable fibres and micronutrients in such foods might play a beneficial role via modulation of microbial community structure (such as increasing diversity and/or changing microbial communities to favour 'protective' over 'pathogenic' bacteria) and function and/or anti-inflammatory effects. CONCLUSION: Available data are weak but suggest tailoring dietary recommendations according to pouch phenotype/behaviour and pouchitis risk might improve outcomes. More sophisticated dietary strategies that utilise the physiological and pathophysiological effects of dietary components on ileoanal pouches have potential to further improve outcomes. Well designed, adequately powered studies are required.

The Implications of Pouch Physiology.

INTRODUCTION: Patients undergoing an IPAA experience a completely different physiology of defecation than when they had a rectum. The new "normal" is poorly appreciated and incompletely understood, and the lack of understanding has implications for pouch function. This technical note lays out the physiology of defecation with an ileal pouch and its implications for patients and surgeons. TECHNIQUE: An intestinal pouch acts as a reservoir because the united antegrade and retrograde peristaltic loops produce no evacuatory pressure. Defecation occurs by gravity. Efficient defecation results in fewer stools, but inefficient defecation may cause stool frequency, incontinence, obstruction, constipation, and pouch inflammation. The technical aspects of pouch construction that impact emptying include a long efferent limb of an S-pouch, any degree of twist in the pouch body, afferent limb syndrome, and anal stenosis. RESULTS: Constructing a pouch with no twists and with an open anus, maintaining liquid stool, and encouraging unhurried defecation can improve pouch function. CONCLUSIONS: Understanding pouch physiology is important in optimizing pouch function and maintaining patient expectations.

Better Function With a Colonic J-Pouch or a Side-to-end Anastomosis?: A Randomized Controlled Trial to Compare the Complications, Functional Outcome, and Quality of Life in Patients With Low Rectal Cancer After a J-Pouch or a Side-to-end Anastomosis.

BACKGROUND INFORMATION: We aimed to compare prospectively the complications and functional outcome of patients undergoing a J-Pouch (JP) or a side-to-end anastomosis (SE) for treatment of low rectal cancer at a 2-year time point after resection for rectal cancer. METHODS: A multicenter study was conducted on patients with low rectal cancer who were randomized to receive either a JP or SE and were followed for 24 months utilizing SF-12 and FACT-C surveys to evaluate the quality of life (QOL). Fecal incontinence was evaluated using the Fecal Incontinence Severity Index (FISI). Bowel function, complications, and their treatments were recorded. RESULTS: Two hundred thirty-eight patients (165 males) were randomized with 167 final eligible patients, 80 in the JP group and 87 in the SE group for evaluation. The mean age at surgery was 61 (range 29 to 82) years. The overall mean recurrence rate was 12 of 238, 5% and similar in both groups. COMPLICATIONS: Overall, 37 of 190 (19%) patients reported complications, 14 of these were Clavien Dindo Grade 3b and 2 were 3a: leak 3 (2 JP,1 SE), fistula 4 (1 JP, 3 SE), small bowel obstruction 4 (3JP, 1 SE), stricture 4 (3 SE, 1 SA), pouch necrosis 2 (JP), and wound infection 5 (2 JP, 3 SE). QOL scores using either instrument between the 2 groups at 12 and 24 months were similar (P > 0.05). Bowel movements, clustering, and FISI scores were similar. CONCLUSION: At time points of 1 and 2 years after a JP or a SE for low rectal cancer, QOL, functional outcome, and complications are comparable between the groups. Although choosing a particular procedure may depend on surgeon/patient choice or anatomical considerations at the time of surgery, SE functions similar to JP and may be chosen due to the ease of construction.

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.

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 < 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.

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.

Outcomes of salvage surgery for ileal pouch complications and dysfunctions. the experience of a referral centre and review of literature.

BACKGROUND AND AIMS: Failure rates of restorative proctocolectomy with ileo pouch-anal anastomosis (IPAA) range between 3.5 and 15%. Salvage surgery aims to preserve the pouch and transanal evacuation. We report our experience with salvage, review the outcomes of revisional pouch surgery, and propose a classification of pouch dysfunction. METHODS: We collected data on patients undergoing pouch salvage surgery between 1987 and 2014 at our hospital. Pre- and post-salvage functional data were assessed. Function at the 3-year follow-up was compared with that of matched IPAA controls (study patients:controls, 1:3). RESULTS: Considering only patients who underwent primary IPAA at our centre (n = 31), 5-year failure was higher after salvage compared with primary IPAA (28.8 vs 5.7% log rank test, p = 0.005). Overall, we included 39 patients, with eight additional patients who received primary IPAA elsewhere, undergoing 46 procedures. Most patients had a J-pouch (74.4%) and needed salvage for septic complications. A transperineal approach was used in 22 patients, whereas 17 underwent abdominal salvage, with 77.3 and 64.7% success rates, respectively. Minor surgery was effective but required repeated procedures. Overall failure was 28.2% at a median follow-up of 42 (1-153) months. A significant decrease in bowel frequency (p = 0.021) and rate of urgency (p = 0.009) was observed at the 3-year follow-up after salvage in 25 patients available for comparison. Functional results after major salvage procedures were poorer compared with healthy IPAA controls (p = 0.003). CONCLUSIONS: Salvage surgery is effective and safe in experienced teams, but the 5-year failure rate is higher after salvage than after successful primary pouch surgery. Sepsis brings about a higher risk of failure compared with mechanical causes of dysfunction.

Colonic J pouch neo-rectum versus straight anastomosis for low rectal cancers.

AIM: The development of sphincter saving procedures for low carcinoma rectum has been the consequence of oncological and technological factors. The major disadvantage associated with these procedures is the development of anterior resection syndrome because of the resection of rectal reservoir. Colonic J pouch (CJP) neorectum has been practiced as an antidote to overcome this problem. We are working at a tertiary care center, which is a high volume center for rectal cancers. We thought it worthwhile to assess the efficacy of J Pouch neorectum viz.-a-viz. a straight coloanal anastomosis for low rectal cancers. MATERIALS AND METHODS: Hospital based prospective randomized study (June 2007-December 2009) low rectal cancers (4-12 cm from the anal verge). One group (20 patients) subjected to low/ultralow anterior resection with straight anastomosis (SA) and other group (22 patients) to CJP. The two groups were compared on the basis of functional outcome. RESULTS: Anastomotic leak, strictures, frequency of bowel movements, nocturnal bowel movements, use of retarding medication and incontinence to solids, liquids and gases were seen more in SA group. All these findings were statistically significant. CONCLUSIONS: We conclude that CJP has a significant functional advantage over SA and improves the overall quality-of-life in patients of low rectal cancers and the advantage persisted over a period of more than 30 months.

Factors affecting the healing of the perineum following surgery.

INTRODUCTION: The aim of this study was to establish patient and procedural factors associated with the development of an unhealed perineum in patients undergoing a proctectomy or excision of an ileoanal pouch. METHODS: A review of 194 case notes for procedures performed between 1997 and 2009 was carried out. All patients had at least 12 months' follow-up. Univariate and multivariate analyses were performed in 16 parameters. For those patients who developed an unhealed perineum, Cox regression analysis was performed to establish healing over a 12-month period. RESULTS: Two hundred patients were included in the study, of which six had unknown wound status and were subsequently excluded. This left 194 study patients. Of these, 86 (44%) achieved primary wound healing with a fully healed perineum and 108 (56%) experienced primary wound failure. With reference to the latter, 63 (58%) healed by 12 months. Comparing patients with an initially intact perineum with those with initial wound failure showed pre-existing sepsis was highly relevant (odds ratio: 4.32, 95% confidence interval [CI]: 2.16-8.62, p<0.001). In patients who had an unhealed perineum initially, perineal sepsis and surgical treatment were both significantly associated with time to healing (hazard ratio [HR]: 0.54, 95% CI: 0.31-0.93, p=0.03; and HR: 0.42, 95% CI: 0.21-0.84, p=0.01). CONCLUSIONS: The presence of pre-existing perineal sepsis is associated with an unhealed perineum following proctectomy in inflammatory bowel disease (IBD) and non-IBD surgery. Further studies are indicated to establish perineal sepsis as a causative factor.

Manometric evaluation of evacuatory difficulty (dyschezia) in ileal pouch patients.

BACKGROUND: Dyschezia occurs in patients with ileal pouch-anal anastomosis. There are limited data on the mechanisms of this condition. We hypothesized that paradoxical contractions may contribute to dyschezia in those patients with mechanical or inflammatory pouch conditions. This study was aimed to evaluate the underlying manometric abnormalities in this population. METHODS: In this retrospective analysis, we screened our Pouchitis Registry for patients with dyschezia and underlying inflammatory bowel disease. Patients having undergone anopouch manometry were considered eligible and included. Patients without inflammatory or structural diseases of the pouch (the functional pouch disorder [FPD] group) were compared with those with inflammatory or structural diseases (the inflammatory/structural pouch disorder [ISPD] group). Demographic, clinical, manometric, and laboratory variables were analyzed. RESULTS: A total of 45 patients were included; of which, 21 (46.7%) were female. The median age of patients in the FPD group (n = 10) and ISPD group (n = 35) were 41 (interquartile range =32.5-56) years and 40 (interquartile range = 28-49) years, respectively (P = 0.469). There were no differences in the demographic, clinical, and laboratory variables between the 2 groups, with the exception of the modified Pouch Disease Activity Index. For manometric evaluations, paradoxical contractions and failure of balloon expulsion occurred in 50.0% and 60.0%, respectively, of the FPD group and in 17.1% and 20.0%, respectively, of the ISPD group (P = 0.048 and 0.043, respectively). CONCLUSIONS: In this cohort, manometric evaluation demonstrated that paradoxical contractions occurred more frequently in patients with FPD than in those with inflammatory/structural conditions. This suggests that the underlying physiologic mechanisms of dyschezia in these patients differ.

Primary and secondary restorative proctocolectomy for familial adenomatous polyposis: complications and long-term bowel function.

AIM: The aim of the study was to evaluate intra-operative difficulties, complications and long-term bowel function in polyposis patients undergoing conversion of an ileorectal anastomosis to an ileoanal pouch, compared with patients with a primary ileoanal pouch operation. METHOD: A national register-based retrospective study was performed with clinical follow-up and a questionnaire on long-term bowel function. RESULTS: There were 84 patients in the study: 59 (70%) had a primary pouch operation and in 25 (30%) a secondary pouch procedure was attempted. This was abandoned, in one case, leaving 24 patients who had a successful secondary restorative proctocolectomy. The median (range) follow-up was 123 (0-359) months. There were no intra-operative difficulties in the 59 primary operations, but intra-operative difficulties were reported in nine of 25 secondary operations (P < 0.001). Complications within 1 month of surgery occurred in six of 59 primary operations and in none of 24 secondary operations (P < 0.001); and late surgical complications occurred in eight of 55 primary operations and in eight of 24 secondary operations (P = 0.13). The only difference in bowel function was a lower frequency of nocturnal defaecation after secondary pouch formation (P = 0.02). CONCLUSION: Reoperation with proctectomy after a previous ileorectal anastomosis and conversion to restorative proctocolectomy is feasible in polyposis patients, with morbidity and functional results similar to those seen after a primary pouch operation.

Diagnosis and differential diagnosis of Crohn's disease of the ileal pouch.

Approximately 20%-30% of patients with ulcerative colitis will eventually require colectomy despite recent advances in medical therapy. Ileal pouch-anal anastomosis has become the surgical treatment of choice. A subset of patients with ileal pouches can develop Crohn's disease or a Crohn's-disease-like condition of the ileal pouch after surgery. Diagnosis, differential diagnosis, and management of Crohn's disease of the ileal pouch have been challenging. A combined assessment of clinical history, endoscopy, histology, abdominal/pelvic imaging, and examination under anesthesia is often necessary for accurate diagnosis, disease classification, management, and prognosis. A multidisciplinary approach with gastroenterologists, colorectal surgeons, gastrointestinal pathologists, and radiologists is advocated.

J-pouch vs side-to-end coloanal anastomosis after preoperative radiotherapy and total mesorectal excision for rectal cancer: a multicentre randomized trial.

AIM: Comparison of functional and surgical outcome of the J-pouch with the side-to-end coloanal anastomosis after preoperative radiotherapy and total mesorectal excision in rectal cancer patients. METHOD: In a multicentre study, patients with a carcinoma of the lower two-thirds of the rectum were randomized to either a J-pouch or a side-to-end reconstruction. Primary outcome was function of the neorectum 1 year after surgery. A functional outcome [COloREctal Functional Outcome (COREFO)] questionnaire, and two quality of life questionnaires (EORTC-QLQ-CR38 and SF-36) were to be completed by all participants preoperatively, and 4 and 12 months postoperatively. Independent data managers recorded surgical outcome. A group size of 30 patients in each group was calculated based on a 15-point difference of the COREFO scale. RESULTS: In total, 107 patients were randomized, 55 in the J-pouch group and 52 in the side-to-end anastomosis group. The COREFO incontinence scale at 4 months and the total functional outcome at 4 and 12 months showed better results for the J-pouch group in comparison with the side-to-end anastomosis group. The remaining COREFO scales (frequency, social impact, stool-related aspects and bowel medication), surgical outcome (complications, reoperations, length of hospital stay, readmissions and mortality) and quality of life did not show significant differences between treatment groups. CONCLUSION: The overall results of a coloanal J-pouch and a side-to-end anastomosis are comparable, although functional results are slightly better with a J-pouch. The side-to-end anastomosis is technically less demanding and therefore a justified alternative in sphincter-saving surgery.

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.

Long-term quality of life in pouch patients compared with stoma patients following rectal cancer surgery.

AIM: Low and ultralow anterior resection for rectal cancer with colorectal or coloanal anastomosis does not compromise oncological results compared with abdominoperineal excision. Although avoidance of a permanent colostomy is regarded as beneficial for a patient's quality of life (QoL), patients undergoing sphincter-sparing surgery may develop a number of functional problems. A colonic pouch significantly improves functional outcome after rectal resection and low anastomosis and may positively influence QoL. The aim of this study was to compare QoL in long-term survivors who underwent ultralow anterior resection with total mesorectal excision and colonic J-pouch anastomosis (CPA) with patients treated with abdominoperineal excision (APE) and end colostomy for rectal cancer. METHOD: The medical records from our institution's prospectively maintained rectal cancer database of 151 patients who underwent surgery for ultralow rectal cancer from 2001 to 2007 were analysed. QoL in 59 eligible patients was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 core and Colorectal Cancer 29. Results were compared for patients with CPA and APE. RESULTS: The median follow-up in the 59 patients was 74 (37-119) months. QoL was good in all patients, but it was better in CPA than in APE patients. Global health status (P = 0.009), physical functioning (P = 0.0002), role functioning (P = 0.03), cognitive functioning (P = 0.046), social functioning (P = 0.002), body image (P = 0.053), embarrassment (P = 0.002) and urinary frequency (P = 0.003) were significantly improved for patients with CPA. CONCLUSION: QoL after rectal resection and CPA was better than after APE in several respects. However, QoL should not be regarded as an isolated concept but rather as one of several possible clinical outcomes of interest.

Resultados funcionales del reservorio ileal / Functional results of ileal pouch

Background: Proctocolectomy with ileal pouch and posterior pouch anal anastomosis is the treatment of choice of severe ulcerative colitis and polyposis. Aim: To evaluate the functional results of ileal pouch anal anastomosis. Material and Methods: Retrospective assessment of all patients subjected to an ileal pouch anal anastomosis. Pouch function was evaluated using Oresland score that goes from 0 or perfect to 15 or bad. Results: During a 10 years period, 35 patients were operated. Ten patients aged 19 to 67 years were treated for an ulcerative colitis and nine, aged 18 to 54 years for a familial adenomatous polyposis. Global complication rate of the procedure was 20 percent. Late complication rate was 17 percent. Specific complication rate of the rectal- ileal pouch anastomosis was 6 percent. Specific late complications of the technique were only observed in six of 20 patients with ulcerative colitis. Pouch failure was observed in two patients (6 percent). Global Oresland score was 3.2. Seventeen of 22 patients with ulcerative colitis and seven of eight patients with polyposis had a satisfactory or acceptable score. Patients had a mean of 4.4 bowel movements per day (range 1 to 15) without differences according to the underlying disease. Conclusions: Eighty percent of patients subjected to an ileal pouch anal anastomosis reported an Oresland score of less than seven, that is satisfactory in terms of quality of life.

Introducción: La proctocolectomía con reservorio ileal y anastomosis reservorio-anal (RIARA) es el tratamiento quirúrgico de elección en la colitis ulcerosa grave y las poliposis. Objetivo: Evaluar resultados funcionales de la RIARA. Pacientes y Método: Evaluación retrospectiva de todos los pacientes intervenidos por una RIARA en forma consecutiva. Los resultados funcionales se evaluaron mediante entrevista según el escore de Õresland. Resultados: En un período de 10 años se intervinieron 35 pacientes, 26 por colitis ulcerosa (CU) (edad promedio 36,8; extremos 19-67) y 9 por poliposis adenomatosa familiar (PAF) (edad promedio 38,8; extremos 18-54). La morbilidad global de la RIARA alcanza al 20 por ciento y las complicaciones tardías se elevan al 17 por ciento. La morbilidad específica de la RIARA fue 5,6 por ciento. Las complicaciones tardías específicas de la técnica se presentaron exclusivamente en el grupo CU (6/30=20 por ciento) y la falla del reservorio alcanza al 5,7 por ciento (2 casos). El puntaje global de Õresland fue 3,2, sin diferencias entre ambos grupos. Hubo 17 de 22 (77 por ciento) pacientes con un puntaje satisfactorio o aceptable en el grupo CU y 7 de 8 (88 por ciento) en el grupo PAF. El promedio de evacuaciones en 24 horas fue 4,4 (extremos 1-15) en la serie global, sin diferencias entre ambos grupos. Conclusión: El 80 por ciento de los pacientes sometidos a una RIARA tienen un escore menor de 7 en la escala de Õresland, lo que equivale a una calidad de vida similar a la población general. Aunque los resultados funcionales de la RIARA no son perfectos, la calidad de vida y la satisfacción del paciente son satisfactorias.

Pouch function and gastrointestinal complications during pregnancy after ileal pouch-anal anastomosis.

OBJECTIVE: To estimate the risk of gastrointestinal and pouch complications and alterations in pouch function related to pregnancy in women treated with ileal pouch-anal anastomosis (IPAA). METHODS: Pregnancies following IPAA were identified in our center, and in the literature through MEDLINE and PUBMED searches. The incidence of each complication was calculated. Pouch function was compared before and after pregnancy, by mode of delivery, and between women who became pregnant versus those that did not. RESULTS: The incidence of complications in 283 pregnancies after IPAA was 12.7% including antepartum (2.8%) or postpartum (6.7%) small bowel obstruction, pouchitis (1.8%), and perianal abscess (0.4%). Stool frequency and incontinence were not significantly affected by pregnancy or mode of delivery. CONCLUSION: Pregnancy after IPAA is overall safe, associated with limited complications and no significant alteration in pouch function. Vaginal delivery appears as safe as cesarean section for most women.
