Anorectal function in children after ileoanal pull-through.
Mucosal proctectomy and ileoanal pull-through is increasingly used in children requiring total colectomy for ulcerative colitis or familial polyposis. Excellent continence can be achieved with this procedure, and it avoids proctocolectomy and permanent ileostomy. We have evaluated prospectively anorectal function in nine consecutively treated children who underwent ileoanal pull-through. Patients were 8 to 17.5 years of age (median, 11.3 years) at the time of surgery; seven had ulcerative colitis, and two had familial polyposis. Anorectal evaluation was performed before colectomy and ileoanal pull-through, following ileoanal pullthrough, after rectal training, and then at yearly intervals. A biofeedback "rectal training" program was instituted 6 weeks after ileoanal pull-through and a contrast study documenting integrity of the pouch. The program consisted of an initial biofeedback session with the motility unit, followed by daily instillations, through a catheter, of progressively larger volumes of water (from 1 to 6 oz, increasing 1 oz per week) into the ileal pouch. Patients were instructed to retain the water and participate in normal activities after the instillation. This protocol acclimated the patient to sensing distension of the pouch and using the sphincters. The follow-up period ranges from 1 to 4.5 years (median, 2.2 years). All patients are continent by day and night. One patient has nocturnal incontinence with episodes of pouchitis. Stool frequency is three to eight movements per day (median, four), with none at night. Preoperative resting rectal sphincter pressures averaged 74.3 +/- 23.1 mm Hg (mean +/- standard deviation), and a maximum squeeze pressure was 93.9 +/- 25.3 mm Hg.(ABSTRACT TRUNCATED AT 250 WORDS)
