RESTORATION OF ANUS IN SITU BY INTERNAL AND EXTERNAL SPHINCTER RECONSTRUCTION TO TREAT 21 PATIENTS WITH MIDDLE AND LOW RECTAL CARCINOMA

Objective:To investigate the clinical effect of restoration of anus in situ by internal and external sphincter reconstruction in the treatment of middle and low rectal carcinoma.Methods:An operation was designed to reconstruct internal and external sphincter of anus in 21 patients with middle and low rectal carcinoma. The operation was used by Mile's procedure.Internal sphincter was reconstruced by folding colon and keeping two amputated end of puborectal muscle to reconstruct external sphincter by perineal superficial transverse muscle.Results:In all 21 patients there is no death in operation. 14 cases have an excellent postoperative function,4 cases have a good postoperative function, only one has common postoperative function.Conclusion:The reconstruction of anus in situ by internal and external sphincter reconstruction has a good clinical effect and is worthy of popularization.
