This would facilitate the adoption of anus saving operation.Before and after fully isolation of the rectum in low ratal cancer surgery, the distance between the lower tumor margin and the anorectal line was measured by the same rectuscope introduced through the anus.The two results were compared .The average lengthening was less than 1 cm if the lower tumor marginanorectal line distance was 5 cm.It was 1─2 cm if the lower tumor margin-anorectal distance was 6 cm.It was more than 2 cm if the distance was 7─9 cm.The loosening and lengthening of the rectal canal was related to the presence of lymphnode metastasis and the skill of the operator.The lengthening was also influenced by the body build of the patient,involvement of the rectal circumference and the Dukes stage. Modified Park's operation,trans abdominosacral resection with anastormosis of rectum,and anterior resection on transpubic approach are indicated for those in whom the lower tumor margin-anorectal line distance was 5 cm The rectectomy-anastomosis in the abdominal cavity(Dixon's operation)is indicated for those in whom the lower tumor margin-anorectal line was 6 cm.If manual anastomosis is difficult,stapling device may be used. The anus saving resection is easy if the distance was 7─9 cm.展开更多
