The anatomy and histology of the rectal muscular cuff was studied in 15 dogs with an ileal pouch-anal anastomosis. Eight channel, three-dimensional anal manometry showed normal maximal squeeze pressure (128 +/- 20 mm Hg) compared to a control group (135 +/- 4 mm Hg). The rectal muscular cuff showed complete absence of the cuff in three cases. In 12 dogs, the rectal cuff was retracted to a length of less than 1 cm, the muscle fibers were degenerated and fibrotic. The results in the canine model and the clinical results of patients with an ileal pouch-anal anastomosis with a cuff demonstrated that a rectal muscular cuff is not essential to maintain continence after ileal pouch-anal anastomosis.
对15只接受回肠贮袋肛管吻合术的犬的直肠肌袖进行了解剖学和组织学研究。与对照组（135±4 mmHg）相比，八通道三维肛门测压显示最大挤压压力正常（128±20 mmHg）。直肠肌袖在3例中完全缺失。在12只犬中，直肠肌袖退缩至长度小于1 cm，肌纤维变性和纤维化。犬模型的结果以及接受带肌袖回肠贮袋肛管吻合术患者的临床结果表明，回肠贮袋肛管吻合术后，直肠肌袖对于维持控便并非必不可少。
