吻合口狭窄是食管贲门手术三大并发症之一。传统上多采用食道扩张器扩张以及置入金属支架、再手术等。扩张疗法短期效果明显 ,但易反复发生狭窄 ,支架及手术患者多不易接受。我们将电化学治疗用于吻合口狭窄的治疗 ,经过1～ 6ｍｏｎ的观察 ,有效率 91 6 % ,近期效果明显 ,优于? Anastomotic stenosis is one of the three major complications of esophageal cardia surgery. Traditionally, esophageal dilators have been used to expand and insert metal stents, reoperations, and the like. The short-term effects of dilation therapy are obvious, but stenosis is easy to occur repeatedly, and stents and surgical patients are not easily accepted. We used electrochemical therapy for the treatment of anastomotic stenosis. After 1 to 6mon observation, the effective rate was 91.6%. The recent effect was obvious.
