内镜高频电刀切除食管癌术后吻合口狭窄

ENDOSCOPIC TREATMANT ANASTOMOTIC CICTRICIAL STENOSIS AFTER RESECTION OF ESOPHAGEAL CANCER BY ENDOTHERN KNIFE.

用自制针式高频电刀于内镜下切除食管癌术后吻合口疤痕狭窄组织。共进行８９例、２６２次。其中，中上段狭窄５２例（５８．４２％），中下段狭窄３７例（４１．５８％）。吻合口＜２．０ｍｍ呈闭合状４０例，＜３．０ｍｍ１７例，＞３．０ｍｍ１６例，有１６例被食物团嵌顿。切除疤痕后１次即通畅者６２例，作２次、３次通畅者各１１例，作８１次、４３次、１２次、５次、４次通畅者各１例（前２例为膜蹼样疤痕增生狭窄，每１－３月需重复治疗１次）。本项治疗技术疗效可靠，安全性好，值得推广。

Anastomotic cicatricial stenosis after resection of esophageal cancer were treated by self- making electric knife through endoscipe.Fifty two cases were located in upper segment while 37 cases in middle-lowere part.Anastomotic diameter of 40 cases were less than 2.0mm,17 cases less than 3.0mm. Sixteen cases more than 3.0mm. Anastomotic stoma were incarcerated by food in 16 cases.The operatic procedure:First,the cicatricial stenosis was resected and became'*'shape by electric knife,then dilated by baloon catheter and by endoscope.sitytwo cases of stenosis were unobstrated(can swallow solid food)after one time treatment ; 11 cases each needed 2 and 3 times;1 case each needed 4 , 5 , 12 , 43and 81 times ,respec- tively. The last 2 cases were treated repeatly every 1- 3 months. The authors think that this procedure is ef- fective and safe. The technique is mastered easily and could be wildely used.
