食管空肠吻合口瘘为全胃切除术后最严重的并发症。针对其发生原因，我们对食管空肠吻合技术进行了一些改进。至今已采用该法行１００例全胃切除术，术后无一例发生吻合口瘘。我们认为，术中注意保持食管断端血运，确保无张力吻合为预防吻合口瘘发生的关键。 The esophagojejunostomy fistula is the most serious complication after total gastrectomy. For the reason of its occurrence, we have made some improvements to the esophagojejunostomy technique. So far, 100 cases of total gastrectomy have been performed using this method, and no postoperative anastomotic leakage occurred. We believe that the intraoperative attention to maintaining blood supply to the broken end of the esophagus ensures that tension-free anastomosis is the key to prevention of anastomotic leakage.
