Straight ileo-anal anastomosis with myectomy as an alternative to ileal pouch-anal anastomosis in restorative proctocolectomy.
Restorative proctocolectomy with various types of reservoir is widely used in the elective surgery of ulcerative colitis and familial adenomatous polyposis. Both, advantages and disadvantages of this procedure are well known and documented. Straight ileo-anal anastomosis (IAA) yields unsatisfactory clinical results due to the lack of storage capacity of the distal ileum and the frequency of bowel movements related to high pressure ileal waves. In an attempt to create an alternative to the above procedures, we have performed a straight ileo-anal anastomosis with two rectangular (10 cm x 1 cm) myectomies down to 2 cm, above the anastomotic line. The two myectomies are spaced at 120 degrees to each other and to the mesenteric border of the ileal loop. The rationale of this approach is to reduce the peristaltic drive of the ileum by weakening the muscular wall. This study presents the results in three patients operated on with this new method in the last year.
