Colectomy with rectal mucosectomy and ileoanal anastomosis in young patients. Its use for ulcerative colitis and familial polyposis

R. L. Telander and J. Perrault

Twenty-five children and young adults underwent colectomy with rectal mucosectomy and ileoanal anastomosis for chronic ulcerative colitis or familial polyposis. Follow-up ranged from three to 35 months. A simpler and shorter modification of the operation was used in 12 patients. Balloon catheter dilations were performed in nine patients before closure of the ileostomy to begin enlargement of the neorectum; 24 patients underwent closure of their temporary ileostomy. All patients are alive and well and participate full time in school or work. Two patients had mechanical bowel obstruction; on critical retrospective review, one patient was found to have Crohn's disease that necessitated removal of the rectal cuff. The clinical result was considered excellent in 11 patients, good in seven, fair in three, and poor in three. A gradual decrease in frequency of stooling was observed as the neorectum enlarged during the first year postoperatively. All patients had very good anal sphincter tone with voluntary rectal continence. Although some soiling and leakage occurred, especially during sleeping, these complications decreased with time.
