Background. The ileal anal pull-through procedure has become the most frequently used cointinence sparing procedure for patients with ulcerative colitis or familial polyposis. Areas of controversy concern the use of temporary ileostomies, and the extent of the rectal mucosectomy. The current report presents a single surgeon's experience with mucosectomy to the perianal skin (squamous mucosectomy), with ileal J-pouch reservoir construction and temporary ileostomy. Methods. We reviewed the records of 105 consecutive patients undergoing this procedure by a single surgeon during a 5-year period. One hundred percent follow-up was achieved. Results. There was 100% gross fecal continence, with 5% of patients expressing rare day time leakage, and 28% having intermittent nocturnal leakage. There were no instances of pelvic sepsis, and no pouches have been removed. The diverting ileostomy was associated with 6% morbidity. Conclusions. We conclude that the rectal mucosectomy can be safely extended to the levels of perianal skin with no loss in continence or function. We recommend that this be adopted as the standard for this procedure to ensure complete eradication of the underlying pathologic condition.
