Abstract: Objective: To study the procedure,effect and safety of treating esophageal cardiac and anastomotic mouth stricture by dilation and implantation of stents under endoscopy.Methods: Thirty-three cases of esophageal cardiac and anastomotic mouth stricture were treated by inserting a lead through the stricture part under endoscopy and X-ray fluoroscopy,then a Savary-Gilliard dilator was used to dilate the stricture part slowly to 10-15 mm.For those who had malignant stricture,post-operative stricture or recurrence of carcinoma,stents were implanted in addition to ditation.Results: Eighteen cases were treated by dilation only,17 of whom received the therapy for one or two times;and 1 of whom four times;15 cases were treated by dilation,as well as implantation of stents.All were successful for once.After operation,the stricture state decreased Ⅱ degreses by Stooler standard in 28 cases,I degree in 4 cases and did not decrease in 1 case.No severe pain,massive haemoorrhage or perfortion occurred.Conclusions: It is effective and safe to treat esophageal cardiac and anastomotic mouth stricture by dilation and implatation of stents under endoscopy.In the operation,we must make sure that the lead goes through the stricture part and is properly fastened;the stricture part is expanded effectively and the stent implanted in place.
