经腹肛门尿生殖间隙中下段直肠癌根治术

Excision of mid-lower rectal carcinoma through ab-domen and anogenital space

作者自１９９０年１月至１９９３年１２月应用经腹部游离乙状结肠和直肠，经肛门尿生殖间隙切除并吻合治疗男性中下段直肠癌２８例。经肛门尿生殖间隙拖出瘤段肠管在盆腔外完成切除和吻合。随访９～５７个月，无瘤生存２６例，占９２．９％；局部复发１例，占３．５７％。本术式优点为：（１）暴露清楚、切除彻底；（２）创伤小、直视下超低位吻合，操作方便；（３）排便功能恢复好；（４）减少盆腔污染。

Abstract28 men with male mid and lower rectal carcinomawere treated by dissecting sigmoid colon and rectum inthe abdomen through the anogenital space,whichrefers to the potential coronoid space located betweenthe deep transverse perineal muscles and anal sphinctermuscles. The rectal segment was pulled out throughthe anogenital space to accomplish resection and anas-tomosis outside the pelvic cavity. Follow一up for 9～57months showed that 26 cases ( 92.9%)survived with-out recurrence of carcinoma and 1 had local recurrence. The advantages of the procedure include clear explo-ration , minimal trauma, super-lower anastomoses un-der direct vision, good recovery of defecating function,and less contamination of pelviccavity.
