Risk Factors Analysis For Anastomotic Leakage After Anus-preserving For Rectal Carcinoma

Objective: To investigate the anastomotic leakage rate risk factors and treatment methods after anus-preserving for rectal carcinoma.Methods: Three hundred and fourteen patients with rectal cancers (3~14 cm from anal verge) underwent anus-preserving for rectal carcinoma with stapling technique, data were analyzed and compared retrospectively.Results: Anastomotic leakage rate was 7.6%, in which 95.8% (23/24)of patents were treated successfully with tube irrigation alone, 4.2% (1/24) received transverse colostomy after failure of conservative treatment. Age, distance of tumor from anal verge, low albumen, rectal carcinoma with intestinal obstruction, and diabetes were related to the leakage (P<0.05 or 0.01), while sex was not related to leakage.Conclusion: Anastomotic leakage is one of the commonest intraoperative complications after anus-preserving operation for rectal carcinoma; low rectal cancers will have more anastomotic leakage rate; The majority of anastomotic leakage can be treated successfully by tran drainage tube irrigation alone, laparotomy and proximal colostomy is necessary for a few cases. We suggest giving patients enteral nutrition after anastomotic leakage as early as possible.
