Background/AimsDuring the past 4 years, we have experienced a marked reduction in the incidence of esophageal anastomotic leakage and/or stricture coinciding with the use of a mechanical circular stapler for gastric cancer patients.MethodologyWe reviewed medical records of gastric cancer patients who underwent a total or proximal gastrectomy, and compared the leakage or stricture of stapled anastomosis with the hand-sewn anastomosis technique. A total of 390 esophageal anastomosis were performed between January 1978 and August 1997. Two types of mechanical circular staplers were used (EEA and CDH).ResultsAnastomotic leakage occurred in 13 (3.3%) of 390 cases; three (4.5%) of 66 cases with hand-sewn anastomosis, and 10 (3.1%) of 324 cases with stapled anastomosis (EEA: 4.5%, CDH: 0%). The anastomotic leakage rate was significantly lower in the CDH stapler group than in the EEA stapler group. Anastomotic stricture occurred in one (1.5%) of 66 cases of hand-sewn anastomosis, and 16 (4.9%) of 324 cases of stapled anastomosis (EEA: 5.9%, CDH: 2.9%). There were no significant differences in the stricture rate between the hand-sewn group and the stapler group.ConclusionsStapling anastomosis using a CDH stapler led to a reduction in the incidence of anastomotic leakage. Surgeons must, however, continue to be aware of anastomotic stricture.
