Anal Canal Decompression in Prophylaxis of Anastomotic Leakage after Anterior Resection for Rectal Neoplasms
>Objective: To investigate the prophylactic effect of anal canal decompression on anastomotic leakage after anterior resection for rectal neoplasms. Methods: We recruited patients receiving anterior rectal tumor resection in the same operation team from January 2010 to June 2012 in West China Hospital. Demographic data, data of tumor-asso- ciated indication, anastomotic leakage and other early postoperative complications, such as intestinal obstruction, anemia and hypoalbuminemia, were recorded. SPSS 17.0 software was used in data statistics. Results: A total of 432 patients were enrolled, 207 of which were in experimental group while the other 225 were in control group. There was no difference between the baselines in two groups. The leakage rate in experimental group (1.45%) is significantly lower than that in control group (4.89%) (P = 0.044), which has statistical significance. In addition, multivariate logistic regression analysis suggests that diabetes mellitus, BMI > 25 kg/m2, tumor located < 7 cm from anal verge, were independent risk factors for anastomotic leakage (P < 0.001, = 0.001, 0.002). Conclusion: Anal canal decompression is effective in decreasing anastomotic leakage rate on anterior resection for rectal cancer.
