From March 1980 through April 1983. Models GF-1 XF and CF stapling apparatuses for gastrointestinal anastomosis, all domestically made, were used in 203 patients for 316 anastomoses. The types of operation included gastrojejunal.gastroduodenal.Roux-Y gastrojejunal. colo-rectal.esophagogastric. esophago-esophageal. and esophago-jejunal anastomoses, and closure of gastric and duodenal stumps. The technic and results of using such stapling apparatuses were described in detail. No anastomotic leakage or bleeding occurred with exception of one case. The advantages of the stapling apparatus can be summarized as:(1) The anastomotic stoma made by such apparatus was smoother and tidier than that of conventional suturing method; (2)Some anastomoses,which would be technically impossible with conventional suturing technic, were successfully made with the aid of the stapling apparatus; (3) The stapler shortened the operation time. However, it should be emphasized that the operator should familiarize themself with the construction and the method of operation of the stapler beforehand.
