Anal continence following Soave procedure. Analysis of results in 100 patients.

AUTOR(ES)
RESUMO

The Soave procedure is an increasingly popular procedure for the definitive therapy of patients with ulcerative colitis. The authors present their experience with 100 patients in whom total proctocolectomy, rectal mucosal stripping, and ileoanal anastomosis (generally using an S-pouch) were carried out. The physiological and anatomical basis of continence is presented, and anastomosis at the top of the columns of Morgagni is recommended. Of the 100 patients in whom this procedure was performed, there was no mortality either in-hospital or later. Of the 12 patients in whom the anastomosis was done 1 cm above the top of the columns (and thus columnar epithelium was retained), six have recurrent anorectal disease, but all are continent both day and night. Three patients in whom the anastomosis was done at the dentate line have had difficulty with continence; two are now continent, but one, after being totally incontinent for 4 years, has required a permanent ileostomy. Of the 69 patients in whom the anastomosis was done at the top of the columns of Morgagni, five are incontinent at night only and two have seepage during both day and night. Thus, if the anastomosis is done at the level recommended, namely, at the top of the columns of Morgagni, retaining no columnar epithelium and anastomosing the ileal pouch to transitional epithelium (which the authors believe not to be subject to the disease of ulcerative colitis), daytime continence will be achieved in 97% and total day and night continence in 90%. The evidence presented suggests that a properly done pull-through procedure with ileoanal anastomosis is the procedure of choice for ulcerative colitis.
