RESUMEN
BACKGROUND: Patients with medically-refractory ulcerative colitis or advanced neoplasia are often offered an ileal-pouch-anal anastomosis to restore bowel continuity. However, up to 50% of patients can suffer from inflammatory conditions of the pouch, some of which require biological therapy to treat. The aim of this study was to determine the efficacy of each biological agent for the treatment of inflammatory conditions of the pouch. MATERIALS AND METHODS: A comprehensive literature search was performed in the major databases from inception through February 11, 2020, for studies assessing the efficacy of biologics in chronic antibiotic-refractory pouchitis (CARP) and Crohn's disease (CD) of the pouch. Both prospective and retrospective studies were included. The primary outcomes of interest were complete and partial responses were defined within each study. χ 2 test was used to compare variables. RESULTS: Thirty-four studies were included in the systematic review and meta-analysis. Sixteen studies (N=247) evaluated the use of infliximab (IFX), showing complete response in 50.7% and partial response in 28.1% for CARP, and complete response in 66.7% and partial response in 20% for CD of the pouch. Seven studies (n=107) assessed the efficacy of adalimumab. For CARP, 33.3% of patients had a complete response, and 38.1% had a partial response, whereas for CD of the pouch, 47.7% experienced a complete response, and 24.6% had a partial response. Three studies (n=78) reported outcomes with the use of ustekinumab, showing 50% complete response and 3.8% partial response for CARP. For the CD of the pouch, 5.8% had a complete response and 78.8% had a partial response. Seven studies (n=151) reported the efficacy of vedolizumab, showing 28.4% complete response and 43.2% partial response in patients with CARP, whereas 63% of patients experienced partial response in CD of the pouch. IFX had higher rates of complete response in CARP compared with adalimumab ( P =0.04) and compared with vedolizumab ( P =0.005), but not compared with ustekinumab ( P =0.95). There were no new safety signals reported in any of the studies. CONCLUSIONS: Biologics are safe and efficacious in the treatment of chronic, refractory inflammatory conditions of the pouch. IFX seems to be more efficacious than adalimumab and vedolizumab for CARP. Further prospective, head-to-head evaluations are needed to compare biological therapies in the treatment of CARP and CD of the pouch.

OBJECTIVE: To compare the effect of liver transplantation (LT) on ileal pouch-anal anastomosis (IPAA) outcomes in patients with primary sclerosing cholangitis and inflammatory bowel disease (PSC-IBD). BACKGROUND: Patients with PSC-IBD may require both IPAA for colitis and LT for PSC. METHODS: Patients with PSC-IBD from out institutional pouch registry (1985-2022) were divided according to LT status and timing of LT (before and after IPAA) and their outcomes analyzed. RESULTS: A total of 160 patients were included: 112 (70%) nontransplanted at last follow-up; 48 (30%) transplanted, of which 23 (14%) before IPAA and 25 (16%) after. Nontransplanted patients at IPAA had more laparoscopic procedures [37 (46%) vs 8 (18%), P =0.002] and less blood loss (median 250 vs 400 mL, P =0.006). Morbidity and mortality at 90 days were similar. Chronic pouchitis was higher in transplanted compared with nontransplanted patients [32 (67%) vs 51 (45.5%), P =0.03], but nontransplanted patients had a higher rate of chronic antibiotic refractory pouchitis. Overall survival was similar, but nontransplanted patients had more PSC-related deaths (12.5% vs 2%, P =0.002). Pouch survival at 10 years was 90% for nontransplanted patients and 100% for transplanted patients (log-rank P =0.052). Timing of LT had no impact on chronic pouchitis, pouch failure, or overall survival. PSC recurrence was 6% at 10 years. For transplanted patients, graft survival was similar regardless of IPAA timing. CONCLUSIONS: In patients with PSC-IBD and IPAA, LT is linked to an increased pouchitis rate but does not affect overall and pouch survival. Timing of LT does not influence short-term and long-term pouch outcomes.

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP/IPAA) is the procedure of choice for patients with ulcerative colitis (UC), some patients with colonic Crohn's disease (CD), and those with familial adenomatous polyposis (FAP); albeit, owing to its complexity, it should be performed by experienced professionals. RP/IPAA is the recommended surgical treatment for UC when the standard medical therapy is ineffective. This procedure has been demonstrated to provide patients with a good quality of life, such as in FAP patients with extensive disease in the rectum. The CD has been associated with higher rates of perianal involvement and disease recurrence, but some patients with CD limited to the large intestine and minimal perianal or ileal disease may also be considered for this operation. First, all patients undergo a detailed preoperative evaluation that includes a review of previous imaging, pathology, and colonoscopy findings, a perianal examination, an evaluation of the anorectal functions, mechanical bowel preparation, and prophylaxis against deep venous thrombosis and infectious complications. A staged approach is the most commonly preferred technique for RP/IPAA, which can be performed in 2 or 3 stages. The IPAA can be performed by laparoscopic, robotic, or open approach. The type of approach is determined based on the patient's condition, medication used, elective or emergency setting, and the surgeon's expertise level. A successful IPAA requires tension-free pouch anastomosis. The most common IPAA pouch types are the J or S pouches; alternatively, an H pouch may be created, which is mainly used in redo pouches. In experienced centers, > 95% of the patients become stoma-free in 10 years. IPAA is a complex procedure, and the complications after pouch surgery are pouchitis, pelvic sepsis, pouch failure, or anastomotic stricture. The majority of long-term complications can be prevented in such cases with a comprehensive preoperative evaluation and through the use of appropriate surgical techniques and postoperative care conducted at experienced centers. The techniques for performing RP/IPAA with their long-term outcomes have been reviewed in this article.

OBJECTIVE: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical gold standard in patients with ulcerative colitis (UC). Results are generally satisfactory but there is a significant rate of patients who experience postoperative complications. The aims of our study were to identify the pre- and intraoperative risk factors and their correlation with the reported outcomes. PATIENTS AND METHODS: A retrospective study was conducted on the medical records of all consecutive patients undergoing restorative proctocolectomy with IPAA for UC in our center from 2010 to 2021. Pre- and intraoperative factors were examined and correlated with pouchitis, endoscopic pouchitis, pouch failure, anastomotic leak, postoperative complications classified according to Clavien-Dindo score and stoma outlet obstruction. A univariate and multivariate statistical analysis was performed. RESULTS: Out of 75 patients undergoing 3- or 2-stage IPAA surgery, the coexistence of extraintestinal clinical manifestations and preoperative topical rectal stump therapy for active proctitis were significantly associated with the occurrence of pouchitis (OR=4.4, p=0.03 and OR=7.6, p=0.01). Endoscopic pouchitis was found to be related to preoperative topical rectal therapy (OR=10.2, p=0.007), but not to extraintestinal manifestations of disease. Anastomotic leak was found to be significantly related to pouch failure (OR=22.7, p=0.007). Surgical indication for malignancy increased the risk for early complications (Clavien-Dindo >2) (OR=16.0, p=0.04). Young age was associated with the occurrence of outlet stoma obstruction in patients with recent IPAA surgery (OR=0.97, p=0.05). CONCLUSIONS: Based on observed results, an appropriate preoperative patient assessment aimed at detecting specific risk factors is crucial to identify early or prevent worse outcomes in patients undergoing IPAA surgery.

For the last 40 years, the ileal pouch-anal anastomosis has been used in patients with ulcerative colitis, familial adenomatous polyposis, and occasionally severe constipation to reconstruct the gastrointestinal tract after proctocolectomy. Although the procedure has generally been successful in helping patients avoid an ileostomy, it has come with its own set of problems. These include complications of the surgery such as fistulas and bowel obstruction, persistent inflammation of the pouch known as pouchitis, and functional problems related to the lack of expulsive peristalsis in the pouch. It is this last group of problems that is exacerbated by a poor diet, ill-advised anti-diarrheal medications, anal stenosis and pouch twists. As a consequence, patients with pouch problems are frequently referred for radiologic evaluation, with pouchography, defecation studies, and small bowel imaging commonly requested. In this review, the basic anatomy and physiology of the ileal pouch are discussed to provide a logical baseline against which to measure the anatomy of pouches and its relationship to the symptoms of pouch dysfunction.

BACKGROUND: Pouchitis is a common late complication in patients with ulcerative colitis (UC) who undergo ileal pouch-anal anastomosis (IPAA). The heterogeneous nature of the clinical and endoscopic presentations could affect the evaluation of therapeutic interventions for pouchitis. Thus, identifying the risk factors and clinical outcomes of pouch inflammation at different sites and severity is becoming increasingly important for colorectal surgeons. METHODS: Data on patients who underwent IPAA January from 2008 to June 2022 in our three pouch centers affiliated with the China UC Pouch Center Union were retrospectively collected. Pouchitis was categorized as a different phenotype according to the Chicago Classification. J pouches were classified into short (14 ± 2 cm) and long pouches (22 ± 2 cm) according to the distribution of ileal pouch length in our institute. RESULTS: Altogether, 143 patients with a median follow-up time of 5.0 years (interquartile range: 2.0-8.0) were enrolled. Among them, 41 patients (28.7%) developed pouchitis and 32 patients (78%) had diffuse inflammation of the pouch. Patients with diffuse pouchitis had a higher pouchitis disease activity index and more seriously impaired improvement of long-term quality of life than those with pouch phenotypes. A short J pouch, recurrent UC, and preoperative high white blood cell count were independent risk factors for diffuse pouchitis. Furthermore, a short J pouch could effectively predict the occurrence of diffuse pouchitis with an area under the receiver-operating characteristic curve of 0.614, a sensitivity of 62.5%, and a specificity of 60.4% (p = 0.049) and significantly decreased the overall diffuse pouchitis-free survival compared to a long J pouch (p = 0.0002). CONCLUSION: Diffuse pouchitis is a common phenotype of pouchitis that seriously impairs long-term prognosis. For colorectal surgeons, decision-making regarding pouch construction with an appropriate length should be considered to prevent the development of diffuse pouchitis.

BACKGROUND: Pouchitis is the most common complication following restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). Fecal calprotectin (FC) is a noninvasive indicator of the intestinal inflammatory status. This study was conducted to evaluate the clinical value of the FC concentration for the diagnosis and risk assessment of pouchitis. PATIENTS AND METHODS: This retrospective study involved patients who underwent IPAA for UC at Tianjin Medical University General Hospital from January 2015 to January 2019. The patients were categorized into pouchitis and non-pouchitis groups based on their Pouchitis Disease Activity Index (PDAI) score. Laboratory indicators, including the FC concentration, were collected from both groups. RESULTS: Sixty-six patients with UC after IPAA were included in the study and divided into the non-pouchitis group (n = 40) and pouchitis group (n = 26). The correlation coefficient between the FC concentration and the PDAI score was 0.651 (p < 0.001). Receiver operating characteristic analysis showed that the FC cut-off value for predicting pouchitis was 579.60 µg/g (area under the curve, 0.938). The patients were then divided into three subgroups according to their PDAI score (0-2, 3-6, and ≥7), and significant differences in the FC concentration were found among the three subgroups. The best FC cut-off value for predicting a high risk of pouchitis (PDAI score of 3-6) was 143.25 µg/g (area under the curve, 0.876). CONCLUSIONS: FC is a useful biomarker in patients with pouchitis. Patients are advised to regularly undergo FC measurement to monitor for pouchitis. An FC concentration in the range of 143.25-579.60 µg/g is predictive of a high risk for pouchitis, and further examination and preventive treatment are necessary in such patients.KEY MESSAGESFecal calprotectin can be used to quantify pouch inflammation.Fecal calprotectin can be used to predict a high risk of pouchitis.

BACKGROUND: To date, a few studies indicated that probiotics are beneficial to pouchitis, but no meta-analyses summarized the outcomes of probiotics in pouchitis in detail. OBJECTIVE: This meta-analysis discusses probiotics in the prevention of pouchitis for patients after ileal pouch-anal anastomosis (IPAA) and the relationship between probiotics preventive effect and the duration of therapy and history. METHODS: PubMed, EMBASE and Cochrane Library databases were searched from inception until February 2022. Risk ratio (RR), mean difference (MD) and their 95% confidence interval (CI) were analyzed by Review Manager 5.3. The subgroup analysis was also performed to explore the agent for influencing outcomes. RESULTS: A total of 8 studies were included in this meta-analysis. The incidence of pouchitis in probiotics was significantly lower than that in the control (RR = 0.19, 95%CI [0.12, 0.32], Pâ¢ï⢻⢠0.00001), and the PDAI (pouchitis disease activity index) in probiotics was also significantly lower (MD =-5.65, 95%CI [-9.48, -1.83]). After the subgroup analysis, we found that probiotics work better in the short-term (RR = 0.12, 95%CI [0.04, 0.40], P= 0.0004), but may not achieve the desired effect in the long-term (RR = 1.20, 95%CI [0.40, 3.60], P= 0.75). CONCLUSIONS: Probiotics are beneficial in the prevention of pouchitis after IPAA, especially in the short-term.

BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is used to treat patients with ulcerative colitis or familial adenomatous polyposis who need colectomy. While this procedure substantially improves patient's quality of life and reduces cancer risk, it is associated with a variety of sequelae' including surgical complications, inflammatory disorders, and neoplasia. Pouchitis, cuffitis, and Crohn's disease of the pouch are the most common inflammatory disorders of the pouch and para-pouch. OBJECTIVE: This study aimed to elaborate on the histopathology of common inflammatory and neoplastic disorders of the pouch and para-pouch. DATA SOURCES: A Medline search for English language studies published between 1981 and 2021 using the PubMed search engine. The terms "ileal pouch-anal anastomosis," "pouchitis," "pouchitis activity score," "secondary pouchitis," "Crohn's disease of the pouch," "Crohn's-like conditions of the pouch," "pre-pouch ileitis," "cuffitis," "pouch adenocarcinoma," and "pouch neoplasia" were used. STUDY SELECTION: The published human studies that reported histopathology of common inflammatory and neoplastic disorders of the ileal pouch were selected and reviewed. CONCLUSIONS: Histologic examination plays an essential role in confirming inflammation in pouchitis, identifying etiology and clues for secondary pouchitis, and diagnosing neoplasia. A standardized, simple, and reproducible histologic grading system for pouchitis is needed. Pouch and para-pouch glandular dysplasia diagnosis is challenging and should always be reviewed by at least one gastrointestinal pathologist.

AIM: Pouchitis is a clinically significant complication of ileal pouch-anal anastomosis with its prevalence varying in the literature. Pouchitis is thought to occur more commonly in patients with ulcerative colitis (UC) than in patients with familial adenomatous polyposis (FAP). We conducted a systematic review with meta-analysis of all published literature to report the prevalence of pouchitis in all pouch patients as well as specifically in UC and FAP. We also investigated the prevalence of acute and chronic pouchitis in UC and FAP. METHODS: A meta-analysis was conducted by searching the Embase, Embase Classic and PubMed databases between 1978 and 2021 exploring the prevalence of pouchitis in UC and FAP. We then performed a random effects model in order to find the pooled prevalence of pouchitis and used odds ratios to report differences in the prevalence of pouchitis in UC and FAP. RESULTS: Fifty-nine full papers and conference abstracts were included in the meta-analysis comprising 18 117 patients with UC and 860 with FAP. The prevalence of pouchitis in UC was 0.32 (95% CI 0.27-0.37) and in FAP was found to be 0.06 (95% CI 0.03-0.15). The odds ratio of pouchitis in UC patients compared with FAP patients was 4.95 (95% CI 3.17-7.72, P < 0.0001). CONCLUSIONS: Our findings support the consensus that the prevalence of pouchitis is higher in UC than in FAP. More significantly our findings suggest that the true prevalence of pouchitis is higher than commonly reported in the literature. This literature may help counsel patients prior to undergoing restorative proctocolectomy.

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

BACKGROUND: Ileoanal pouch anastomosis is the surgical treatment of choice for patients with intractable ulcerative colitis. Perianal disease is a feature that is often present in Crohn's disease and infrequently in ulcerative colitis. OBJECTIVE: The aim of this study is to identify the incidence and factors associated with the development of postoperative perianal fistula in patients undergoing ileoanal pouch anastomosis for ulcerative colitis. DESIGN: A prospectively collected database at the time of surgery with subsequent follow-up was utilized. SETTING: The study was conducted at a high-volume single institution. PATIENTS: We studied a series of 475 consecutive patients with preoperative diagnosis of ulcerative colitis who underwent ileoanal pouch anastomosis. MAIN OUTCOME MEASURES: The incidence of postoperative perianal fistula and the factors correlating with its development were primary outcome measures of the study. RESULTS: The overall number of patients developing perianal fistulas was 44 of 475 (9%). Eleven patients with perianal fistula (25%) required return to ileostomy, of which 7 had pouch excision. Patients who developed a postoperative perianal fistula had a younger age at the onset of disease, had a lower age at index surgery, and were more likely to be subsequently classified as indeterminate colitis or Crohn's disease. Patients developing perianal fistulas were also more likely to develop partial dehiscence or stricture of the ileoanal anastomosis. LIMITATIONS: This study spans nearly 40 years during which the surgical procedure evolved. CONCLUSIONS: Young age at the onset of disease, lower age at surgery, and postoperative diagnosis of Crohn's disease and indeterminate colitis were the factors correlating with perianal fistulas. Delayed healing of the ileoanal anastomosis with partial separation and/or stricture also correlated with the onset of perianal fistulas. The severity of rectal inflammation at the time of surgery or the presence of stapled versus handsewn anastomosis did not correlate with the development of perianal fistulas.

FSTULA PERIANAL POSTERIOR A RESERVORIO ILEOANAL EN PACIENTES CON COLITIS ULCERATIVA UNA REVISIN DE PACIENTES OPERADOS EN UN CENTRO PRINCIPAL DE EII: ANTECEDENTES:El reservorio ileoanal es el tratamiento quirúrgico de elección para los pacientes con colitis ulcerativa intratable. La enfermedad perianal es una característica que a menudo está presente en la enfermedad de Crohn y con poca frecuencia en la colitis ulcerativa.OBJETIVO:El objetivo del estudio es identificar la incidencia y los factores asociados con el desarrollo de fístula perianal posoperatoria en pacientes sometidos a reservorio ileoanal por colitis ulcerativa.DISEÑO:Base de datos recopilada prospectivamente en el momento de la cirugía con seguimiento subsecuente.ENTORNO CLÍNICO:El estudio se llevó a cabo en una única institución de gran volumen.PACIENTES:Estudiamos una serie de 475 pacientes consecutivos con diagnóstico preoperatorio de colitis ulcerativa a los que se les realizó reservorio ileoanal.PRINCIPALES MEDIDAS DE VALORACIÓN:La incidencia de fístula perianal posoperatoria y los factores que se correlacionan con su desarrollo fueron las principales medidas de resultado del estudio.RESULTADOS:El número total de pacientes que desarrollaron fístulas perianales fue 44 de 475 (9%). Once pacientes con fístula perianal (25%) requirieron volver a la ileostomía, de los cuales 7 tuvieron resección del reservorio. Los pacientes que desarrollaron fístula perianal posoperatoria tenían edad más temprana al inicio de la enfermedad, menor edad en el momento de la cirugía inicial y tenían más probabilidades de ser clasificados posteriormente como colitis indeterminada o enfermedad de Crohn. Los pacientes que desarrollaron fístulas perianales también fueron más propensos a desarrollar dehiscencia parcial o estenosis de la anastomosis ileoanal.LIMITACIONES:Este estudio abarca casi 40 años durante los cuales ha evolucionado el procedimiento quirúrgico.CONCLUSIONES:Edad temprana al inicio de la enfermedad, menor edad al momento de la cirugía, diagnóstico postoperatorio de enfermedad de Crohn y colitis indeterminada fueron los factores que se correlacionaron con las fístulas perianales. El retraso en la cicatrización de la anastomosis ileoanal con separación parcial y/o estenosis también se correlacionó con la aparición de fístulas perianales. La gravedad de la inflamación rectal en el momento de la cirugía o la presencia de anastomosis con grapas versus anastomosis manual no se correlacionó con el desarrollo de fístulas perianales.

Risk stratification is required to improve the management of pouchitis with ulcerative colitis (UC) patients who undergo ileal pouch-anal anastomosis (IPAA). Recently, the colectomy risk score (CRS) has been used to assess UC severity and predict the need for surgery. We explored whether the CRS predicted pouchitis in patients with UC who underwent IPAA. This retrospective study included 168 UC patients who underwent IPAA. Pouchitis was diagnosed according to the pouchitis disease activity index. The primary endpoint was the cumulative incidence of pouchitis. The risk factors for pouchitis using preoperatively obtained data, including the CRS, were investigated. Based on their CRS, patients were assigned to low- (scores 0-3), intermediate- (scores 4-6), and high-risk (scores 7-9) groups. The incidence of pouchitis was estimated using the Kaplan-Meier curve. CRS validity was assessed using the Cox proportional hazards model. During the median 7.2 (interquartile range [IQR] 2.8-11.1) years' follow-up, 37 (28.5%) patients were diagnosed with pouchitis. Patients with pouchitis had significantly higher CRS than patients without pouchitis (median 7.0; IQR, 4.0-7.0 vs median 5.0; IQR, 3.0-7.0). The cumulative incidences of pouchitis in the low-, intermediate-, and high-risk groups were 10.3%, 18.3%, and 36.1% at 5 years, respectively. Thus, the incidence trended to increase significantly as CRS increased. Multivariate analysis revealed high-risk CRS status was an independent predictor of pouchitis (hazard ratio: 18.03; 95% confidence interval 1.55-210.05). CRS is useful in risk stratification for the development of subsequent pouchitis in patients with UC undergoing IPAA.

BACKGROUND: Restorative proctocolectomy is the procedure of choice in patients with ulcerative colitis refractory to medical therapy. Prepouch ileitis is characterized by mucosal inflammation immediately proximal to the pouch. Prepouch ileitis is uncommon, and long-term follow-up data are lacking. OBJECTIVE: The aim of this study is to report the long-term outcomes of prepouch ileitis. DESIGN: We followed up a cohort of patients with prepouch ileitis that was originally described in 2009. Patients were followed up until the last recorded clinic attendance or at the point of pouch failure. Follow-up data collected included stool frequency, endoscopic findings, treatment, and overall pouch function. SETTING: We accessed a prospectively maintained database at our institution between January 2009 and January 2017. PATIENTS: Three of the 34 patients originally described in 2009 were lost to follow-up; we reanalyzed data on the remaining 31. MAIN OUTCOME MEASURE: The rate of pouch failure was defined as the need for ileostomy or pouch revision. RESULTS: All 31 patients had coexisting pouchitis at index diagnosis of prepouch ileitis. The median length of follow-up from the index pouchoscopy was 98 (range, 27-143) months. Seven (23%) patients who had an index pouchoscopy with prepouch ileitis went on to pouch failure, which is significantly higher than expected (p = 0.03). Five (71%) of these patients had chronic pouchitis, and 2 (29%) had small-bowel obstruction due to prepouch stricture. Two patients had evidence that would support possible Crohn's disease at long-term follow-up. LIMITATIONS: This was a retrospective analysis. Because of the nature of the study, there was some missing information that may have influenced the results. Our study is further limited by small patient numbers. CONCLUSIONS: Prepouch ileitis is associated with a significantly increased risk of pouch failure compared with the overall reported literature for restorative proctocolectomy. Prepouch ileitis does not appear to be strongly predictive of Crohn's disease at long-term follow-up. See Video Abstract at http://links.lww.com/DCR/A480.

BACKGROUND: Creation of a J pouch is the gold standard surgical intervention in the treatment of chronic ulcerative colitis (UC). Pouchoscopy prior to ileostomy takedown is commonly performed. We describe the frequency, indication, and findings on pouchoscopy, and determine if pouchoscopy affects rates of complications after takedown. METHODS: All UC or indeterminate inflammatory bowel disease patients with a J pouch were retrospectively evaluated from January 1994 to December 2014. Cases were defined as having routine (asymptomatic) pouchoscopy after pouch creation but before ileostomy takedown. Controls were defined as having no pouchoscopy or pouchoscopy on the same day as that of takedown. RESULTS: The study included 178 patients (81.5% cases, 18.5% controls). Fifty two percent of pouchoscopies were reported as normal. Common abnormal endoscopy findings included stricture (35%), pouchitis (7%), and cuffitis (0.7%). Length of stay during takedown hospitalization was shorter for cases than controls (3 vs. 5 days; p = 0.001), but neither short- nor long-term complications were statistically different between cases and controls. Abnormalities on pouchoscopy were not predictive for short-term complications (p = 0.73) or long-term complications (p = 0.55). Routine pouchoscopy did not delay takedown surgery in any of the included patients. CONCLUSIONS: Routine pouchoscopy may not be necessary prior to ileostomy takedown; its greatest utility is in patients with suspected pouch complications.

BACKGROUND/AIM: Abdominoperineal resection (APR) has been performed for lower rectal cancer, anal cancer and inflammatory diseases, but is associated with postoperative complications such as inflammation of pelvic dead space or perineal wound infection. We are performing a novel procedure (transanal assisted resection with closure of anal canal, TARC) that resects the intestine by using transanal assist and close the anal canal for patients who do not require resection of the anus and anal canal. PATIENTS AND METHODS: From January 2015 to March 2017, nine patients (seven males, two females) underwent this procedure in our hospital for rectal cancer, recurrent rectal cancer, postoperative refractory pouchitis, and cervical cancer invaded to the rectum. The three patients diagnosed with rectal cancer underwent this procedure by a completely laparoscopic abdominal approach. RESULTS: None developed postoperative dead space inflammation or perineal wound infections. CONCLUSION: TARC seems to allow improved postoperative quality of life as compared to APR.
