BACKGROUND: Postoperative anastomotic strictures produce significant morbidity after esophagectomy. Previous reports have described a variable association between the diameter of the circular end-to-end anastomosis (EEA) stapler commonly used in esophagogastric anastomoses and the incidence of stricture formation. Stapler technology has improved. We investigated an association between stapler diameter and the incidence of postoperative anastomotic strictures in a contemporary series. This has renewed importance given the limited diameter of trans-oral staplers that are being increasingly used. METHODS: Retrospective chart review revealed that of 194 patients undergoing an esophagectomy over a 10-y period (10/1998-8/2008) at our institution, an EEA stapler was used in 91. EEA size information and follow-up were available in 89 patients. Patients were divided into two groups based on EEA size: 'small' = 23-25 mm (n = 24) and 'large' = 28-33 mm (n = 65). Patients with strictures were identified based on symptoms of dysphagia requiring an esophageal dilation procedure. Patients with postoperative leaks were excluded when analyzing for the association of stricture with EEA size, as postoperative leaks are known to be associated with stricture. Wilcoxon and Fisher's exact tests were used for statistical analysis; a 5% α error was accepted. RESULTS: Fifteen (16.8%) of 89 patients developed a stricture postoperatively. The anastomotic leak rate was 3.3%. There was no statistically significant association between EEA size group and stricture formation (P = 0.7506). CONCLUSIONS: No association was found between the size of the EEA stapler used and stricture formation. EEA size should be determined at surgery by the native esophageal diameter.
