    Abstract:
    AIM: The aim of the study was to determine the present state of diverting stoma construction in Japanese cancer centres and to investigate the relationship between symptomatic leakage and diverting stoma after low anterior resection for rectal cancer. METHOD: Two hundred and twenty-two consecutive patients undergoing low anterior resection for rectal cancer located within 10 cm from the anal verge were investigated in a prospective, multicenter study. RESULTS: The overall leakage rate was 9.0% (20/222). Of 31 cases with an anastomosis within 2.0 cm from the anal verge, 22 (71%) had a diverting stoma. Of cases anastomosed within 5.0 cm, the absence of a diverting stoma and tumour size were significantly related to an increased rate of leakage [leakage in 13 (12.7%) of 102 cases without a diverting stoma; in three (3.8%) of 80 cases with a diverting stoma]. Among anastomoses within 2.0 cm from the anal verge, leakage occurred in four (44.4%) of nine cases without and in none (0%) of 22 cases with a diverting stoma. CONCLUSION: We recommend a diverting stoma for an anastomosis within 5.0 cm of the anal verge and strongly recommend it for a very low anastomosis within 2.0 cm.
