食管吻合口瘘是食管、贲门癌切除术后最长见、最危险、最严重的并发症,死亡率高达18.5～57.1%.近年来由于外科技术的不断进步,改进和创新了许多新的吻合方法、如胃腔内食管胃吻合法、食管腔内弹力环扎吻合法、食管置入吻合法、胃浆肌层舌状瓣覆盖食管目粘膜吻合法、隧道式食管胃吻合法、活瓣胃底形成术等,使吻合口瘘的发生率明显降低,但仍在1.7～5.5%之间.因此.术后食管吻合口瘘仍是一个亟待解决的问题.1 机械吻合现在,国内外许多地方均在临床应用管型吻合器和消化道缝合器.我国应用最广的是上海产的GF—Ⅰ型吻合器和XF—60 90型缝合器.应用吻合器和缝合器.不但操作简便、吻合牢靠、 Esophageal anastomotic fistula is the longest, most dangerous, and most serious complication after esophageal and cardiac cancer resection. The mortality rate is as high as 18.5 to 57.1%. In recent years, due to the continuous advancement of surgical techniques, many new anastomoses have been improved and innovated. Methods, such as intragastric esophagogastric anastomosis, esophageal intraluminal elastic cerclage anastomosis, esophageal anastomosis, gastric mucosal lingual flap covering esophageal mucosal anastomosis, tunneling esophagogastrostomy, flap Gastric fundus formation surgery, etc., so that the incidence of anastomotic leakage was significantly reduced, but still between 1.7 to 5.5%. Therefore, postoperative esophageal anastomotic leakage is still a problem to be solved. 1 mechanical anastomosis, many at home and abroad Locally used in the clinical application of tubular anastomosis and digestive tract suturers. The most widely used in China is the Shanghai-made GF-I stapler and XF-60 90 stapler. Application stapler and stapler. Not only easy to operate, Securely fit,
