Endoscopic treatment of benign anastomotic esophagogastric strictures with a biodegradable stent.

摘要

Postoperative benign fibrotic strictures of a cervical esophagogastric anastomosis have a reported incidence of 26% to 46%.1 Factors independently related to development of benign anastomotic strictures are cardiovascular disease, gastric tube compared with colonic interposition, and postoperative anastomotic leakage.1 These strictures bring about morbidity because of dysphagia and weight loss, leading to a decreased quality of life. Several methods have been described to treat these strictures, including balloon dilation, Savary bougie dilation, and Eder Puestow olive dilation. None of these conventional methods has proved to be superior over others with regard to efficacy and safety.2 The median number of dilation sessions varies between 2 and 9 per patient when conventional dilation techniques are used to achieve remission.2 To reduce the number of treatment sessions, dilation has been combined with intralesional steroid injections, revealing a reduction of dilation sessions in uncontrolled series.
