Item Improving quality of life after pouch surgery with a dedicated nurse led follow up programme(Wiely-Blackwell, 2016) Chandrasinghe, P.; Leo, A.; Alison, L.; Perry-Woodford, Z.; Warusavitarne, J.AIM:Bowel function after ileal pouch affects the quality of life (QOL). The aim of the study was to assess if objective evaluation and specialised supportive care improves QOL after pouch surgery.METHOD: Consecutive patients who had an ileoanal pouch were invited to participate in a systematic follow-up regime led by specialised pouch nurse practitioners. The Cleveland global Quality of Life (CGQOL) and specific pouch related symptoms were documented at 6, 12, 24 and 52 weeks after ileostomy reversal. Pearson's Rho coefficient was used to assess the correlation between symptoms and CGQOL. RESULTS: Thirty-nine consecutive patients who had ileoanal pouch surgery were evaluated. Thirty-four had more than two visits and improvement in CGQOL (mean-1.36 ± 0.95) was seen in 27 (79%). There was reduction in CGQOL in 5 patients (15%) and no change in 2 (6%). Daytime frequency (DTF) significantly correlated with mean CGQOL (R = −0.7, P < 0.01). Twenty (59%) of 34 had reduced DTF after intervention. Nocturnal frequency only showed correlation with CGQOL up to 3 months. Incontinence had no impact on the QOL in this cohort. CONCLUSION: DTF has the highest impact on QOL in this cohort. Regular systematic specialised pouch care follow up may achieve better QOL.Item Long-term function after transanal versus transabdominal ileal pouch-anal anastomosis for ulcerative colitis: a multicenter cohort study(Wiely-Blackwell, 2019) Chandrasinghe, P.; Carvello, M.; Wasmann, K.; Tanis, P.; Warusavitarne, J.; Spinelli, A.; Bemelman, W.AIM:The novel transanal approach to ileal pouch-anal anastomosis (ta-IPAA) provides better exposure with lower short-term morbidity in ulcerative colitis (UC). The aim of this study was to assess the long-term outcomes after ta-IPAA versus abdominal IPAA (abd-IPAA) in UC. METHOD:This is a multicentre cohort analysis between March 2002 and September 2017. Patient characteristics, surgical details and postoperative outcomes were compared. The primary end-point was CGQL (Cleveland Global Quality of Life) score at 12 months. RESULTS:374 patients (100 ta-IPAA vs 274 abd-IPAA) were included. Mean CGQL scores were comparable between the two groups (0.75 ± 0.11 vs 0.71 ± 0.14; respectively, P = 0.1). Quality of life (7.71 ± 1.17 vs 7.30 ± 1.46; P = 0.04) and energy level (7.16 ± 1.52 vs 6.66 ± 1.68; P = 0.03) were significantly better after ta-IPAA, while the quality of health item was comparable (7.68 ± 1.26 vs 7.64 ± 1.44; P = 0.9655). Stool frequencies (> 10/24 h:22% vs 21%; P = 1.0) and major incontinence rates (27% vs 26%; P = 0.89) were similar. Thirty-day morbidity rates (33% vs 41%; P = 0.2) and anastomotic leak rates were comparable (6% vs 13%; P = 0.09). CONCLUSION: This study, for the first time, provides evidence of comparable long-term functional outcome of ta-IPAA vs abd-IPAA for UC.Item Item Prospective evaluation of sutured, continuous, and interrupted single layer colonic anastomoses(Taylor and Francis, 1995) Deen, K.I.; Smart, P.J.OBJECTIVE: To evaluate the merits of continuous and interrupted colonic anastomoses. DESIGN: Prospective non-randomised study. SETTING: District hospital, UK. SUBJECTS: 53 Patients (24 male and 29 female) of whom 26 underwent continuous and 27 interrupted sutured colonic anastomoses. MAIN OUTCOME MEASURES: Mortality at 30 days, time taken to complete anastomosis, anastomotic dehiscence and anastomotic stricture. RESULTS: No patient died within 30 days. There were no significant differences in (median, range) time taken to complete the anastomosis (continuous: 15 (7-23) minutes; interrupted: 26 (10-34) minutes, p = 0.27); anastomotic leak rate (continuous 1; interrupted 1) and anastomotic stricture (continuous 1 and interrupted 1). Patients were followed up for a mean of 15 months after continuous and 18 months after interrupted colonicanastomoses. CONCLUSION: As both techniques were equally safe, it is probable that the type of colonic anastomosis done will remain a matter of individual preference.Item Mucosal characteristics of pelvic ileal pouches(British Medical Assosiation, 1991) de Silva, H.J.; Millard, P.R.; Kettlewell, M.; Mortensen, N.J.; Prince, C.; Jewell, D.P.This study aimed to investigate the degree of colonic metaplasia in ileo - anal pouches. Biopsy specimens from 25 patients with functioning pouches, eight of whom had pouchitis, were studied using routine histology, mucosal morphometry, mucin histochemistry, and immunoperoxidase staining with monoclonal antibodies directed towards a 40kD colonic protein and a small bowel specific disaccharidase-sucrase isomaltase. Thirteen patients (including all eight with pouchitis) had subtotal or total villous atrophy and crypt hyperplasia. In this group, nine had colorectal type sulphomucin and the 40kD colonic protein was detected in two. These changes were not observed in patients with less severe villous abnormalities. Sucrase-isomaltase activity was, however, present in all 25 pouch specimens. We conclude that although some ileal pouches acquire certain colonic characteristics, complete colonic metaplasia does not occur.Item Clinical and functional outcome after restorative proctocolectomy(1991) de Silva, H.J.; de Angelis, C.P.; Soper, N.; Kettlewell, M.G.; Mortensen, N.J.; Jewell, D.P.Restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) has been carried out on 88 patients since 1982. Three different pouch designs (J, S and W) were used. Ten pouches had to be removed. Detailed analysis was performed on 61 patients (J = 23, S = 15, W = 23) whose pouches had been functioning for at least 6 months. There was no significant difference in surgical complications before or after ileostomy closure between pouch designs but the hospital stay was greater after construction of an S pouch (P less than 0.05). There were no significant differences in stool frequency, degree of continence or urgency between the three types. Twelve patients with J pouches required antidiarrhoeal medication compared with only one with S and five with W pouches. Only seven patients with S pouches could defaecate spontaneously compared with 22 with W pouches and all patients with J pouches (P less than 0.001). Twenty-five of 29 patients who had preservation of the anal transition zone had perfect continence compared with 23 of 32 with a mucosal proctectomy (P = n.s.). Pouchitis occurred in 13 patients, all of whom had ulcerative colitis. In a subgroup of 23 patients, pouch evacuation was assessed scintigraphically. There was no difference in pouch capacity or total volume evacuated, but spontaneous evacuation was better in J and W pouches compared with S pouchesItem Crypt cell proliferation and HLA-DR expression in pelvic ileal pouches(BMJ Publishing Group, 1990) de Silva, H.J.; Gatter, K.C.; Millard, P.R.; Kettlewell, M.; Mortensen, N.J.; Jewell, D.P.To investigate the nature of the morphological changes that occur in ileal pouches, 26 biopsy specimens from patients with functioning ileo-anal pouches (eight with pouchitis) were studied. Normal ileum (n = 10) was used as a control. Mucosal morphometry (using linear measurements), crypt cell proliferation (CCP) (using the monoclonal antibody Ki67), and epithelial HLA-DR expression (monoclonal antibody CR3/43) were assessed. CCP (expressed as the percentage of Ki67 positive nuclei for each crypt) was significantly higher in pouches with pouchitis, compared with those without, and in pouches without pouchitis compared with normal ileum. CCP values in some pouches without pouchitis approached values found in those with pouchitis. CCP was related inversely to villous height and an index of villous atrophy (VH/TMT), and directly to crypt depth. In the presence of pouchitis there was intense epithelial HLA-DR expression that extended into the crypts. In some pouches with high CCP values, but without clinically important inflammation, surface epithelial HLA-DR expression was weak and patchy. It is concluded that villous atrophy and crypt hyperplasia in ileal pouches are associated with high CCP values. These may be increased even in the absence of active inflammation, and this increase may occur as a response to the new luminal environment.
