摘要

Anal sphincter ablation with permanent colostomy or abdominoperi-neal resection (APR) has been regarded until recently as the standard treatment for patients with low-lying rectal cancers based on the concept that the safe distal resection margin of the cancer should be at least 5 cm (1). However, as many investigators have reported that distal mural spread over 2 cm is rare in distal rectal cancers, it has become accepted that a distal resection margin of 2 cm is sufficient (2, 3), and the result of a 'close shave' at anterior resection were reported, suggesting that a resection margin of 1 cm or less produced an similar oncological outcome to that of a resection margin greater than 1 cm (4).
