Risk Factors of Anastomotic Leak Following Operations for Gastric Cancer in the Elderly

Abstract

The risk factors of anastomotic leak in the elderly following operations for gastric cancer were evaluated by multiple logistic model analysis. Data were taken from 705 operations over a 14-year period. The mean age of patients was 75.8±7.6 years. The significant risk factors for anastomotic leak were amounts of intra-operative bleeding and male gender. No other factors were significant, including age, preoperative associated diseases, preoperative nutritional states and postoperative complications, some of which were, however, significant factors by univariate analyses. We conclude that we should make every endeavor to lower the amount of intra-operative bleeding in order to prevent postoperative anastomotic leaks in the elderly, especially in male patients.
