title: Stapler design and strictures at the esophagogastric anastomosis.
abstract: An apparent reduction in the rate of benign anastomotic stricture after stapled esophagogastrectomy prompted us to review the results obtained with different stapling devices since 1988. We present a retrospective review of 125 consecutive patients undergoing esophageal resection for malignancy with stapled intrathoracic anastomoses. Benign anastomotic stricture was deemed present when a patient required endoscopic dilatation to treat postoperative dysphagia. We found no difference in risk factors not related to stapler size (tumor histologic characteristics, adjuvant therapy) between patients with stricture and patients without stricture. Event-free survival was compared for different stapler diameters as well as for different stapler designs. We found that staplers of smaller diameter were associated with significantly more strictures (p < 0.005). In a comparison of different designs of 25 mm stapler, the newer CDH device (Ethicon Ltd., Edinburgh, United Kingdom) was associated with a similar stricture rate to that associated with other designs (ILP [Ethicon] and EEA [Autosuture Company Division, United States Surgical Corp., Norwalk, Conn.]). For a given stapler diameter, it appears that different stapler designs have no effect on stricture rate.
