We utilized a transoral 21-mm circular stapler for the gastrojejunostomy. Patients with symptoms of anastomotic strictures underwent upper endoscopy by one surgeon (B.C.). A stricture was defined by the inability to pass a 10-mm gastroscope through the anastomosis. Balloon dilation was performed to 12 mm. Records were analyzed retrospectively and statistical analysis including Pearson \u03c7<sup>2<\/sup> statistics, Fisher\u2019s exact test and Student\u2019s t test were used when appropriate. <i>Results:<\/i> Symptomatic anastomotic strictures occurred in 29 (23%) patients. All patients presented with nausea, vomiting and dysphagia. The median time to diagnosis was 52 days (25\u2013309 days). Symptoms resolved after one dilation in 25 (86%) of patients. Two and three dilations were required in 1 (3.5%) and 3 (10.5%) of patients, respectively. No patients had complications or required more than 3 dilations. Age, preoperative body mass index (BMI), and intraoperative blood loss did not correlate with stricture formation. Although nonsteroidal anti-inflammatory drugs were used by 46 (41%) of patients after surgery, there was no correlation with stricture formation. <i>Conclusion:<\/i> Symptomatic anastomotic strictures developed in nearly a quarter of patients who underwent LRYGB utilizing a transoral 21-mm circular stapled gastrojejunal anastomosis. A single endoscopic balloon dilation was usually adequate. Strictures were not predicted by perioperative factors.<\/jats:p>","DOI":"10.1159\/000226289","type":"journal-article","created":{"date-parts":[[2009,7,31]],"date-time":"2009-07-31T11:27:44Z","timestamp":1249039664000},"page":"364-367","source":"Crossref","is-referenced-by-count":37,"title":["Stricture Rate after Laparoscopic Roux-en-Y Gastric Bypass with a 21-mm Circular Stapler: The Cleveland Clinic Experience"],"prefix":"10.1159","volume":"18","author":[{"given":"Fahad","family":"Alasfar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adheesh A.","family":"Sabnis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rockson C.","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bipan","family":"Chand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,7,31]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1381%2F096089203765887598"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2FS1091-255X%2802%2900085-9"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1381%2F096089294765558331"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.gassur.2003.09.016"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1001%2Farchsurg.138.2.181"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9610%2800%2900393-7"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00464-003-8919-x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00464-002-8908-5"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.gtc.2004.12.004"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1381%2F096089202321144540"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1381%2F096089200321593751"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016%2FS0016-5107%2803%2902310-1"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2003-41579"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1381%2F096089203322509291"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.amjsurg.2004.11.026"}],"container-title":["Medical Principles and Practice"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/226289","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/226289","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T23:03:19Z","timestamp":1745449399000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000226289"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":15,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2009,8,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000226289","archive":["Portico"],"relation":{},"ISSN":["1011-7571","1423-0151"],"issn-type":[{"value":"1011-7571","type":"print"},{"value":"1423-0151","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
