This study compares different pouch designs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A systematic review of the literature was performed. A random effects meta\u2010analytical model was used to compare adverse events and functional outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>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\u00a0h 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\u2010time 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>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.<\/jats:p><\/jats:sec>","DOI":"10.1111\/codi.14104","type":"journal-article","created":{"date-parts":[[2018,3,26]],"date-time":"2018-03-26T01:53:37Z","timestamp":1522029217000},"page":"664-675","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["A systematic review and meta\u2010analysis comparing adverse events and functional outcomes of different pouch designs after restorative proctocolectomy"],"prefix":"10.1111","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8864-4350","authenticated-orcid":false,"given":"C.","family":"Simillis","sequence":"first","affiliation":[{"name":"Department of Colorectal Surgery Chelsea and Westminster Hospital NHS Foundation Trust London UK"},{"name":"Department of Surgery and Cancer Imperial College London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Afxentiou","sequence":"additional","affiliation":[{"name":"Department of Colorectal Surgery Chelsea and Westminster Hospital NHS Foundation Trust London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Pellino","sequence":"additional","affiliation":[{"name":"Department of Colorectal Surgery Chelsea and Westminster Hospital NHS Foundation Trust London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Kontovounisios","sequence":"additional","affiliation":[{"name":"Department of Colorectal Surgery Chelsea and Westminster Hospital NHS Foundation Trust London UK"},{"name":"Department of Surgery and Cancer Imperial College London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Rasheed","sequence":"additional","affiliation":[{"name":"Department of Surgery and Cancer Imperial College London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O.","family":"Faiz","sequence":"additional","affiliation":[{"name":"St Mark's Academic Institute Surgical Epidemiological Trials and Outcomes Centre London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.
