Results of mucosal proctectomy versus extrarectal dissection for ulcerative colitis and familial polyposis in children and young adults.
Over a 5-year period, the authors examined 30 consecutively treated patients, aged 16 years or younger, who underwent total colectomy and ileal pouch-anal anastomosis, (IPAA) using two different surgical methods. In 16 patients (group I), extrarectal dissection with stapled J pouch and anastomosis was performed. In 14 patients (group II), mucosal proctectomy with hand-sewn S pouch and anastomosis was performed. The mean follow-up period this study was approximately two years (range, 1 to 5 years). With regard to postoperative complications, quality of life, and occurrence of pouchitis, there were no significant differences between the groups. Stool frequency was not significantly different between the two groups, and approached four bowel movements per day at 1 year after surgery. In both groups, daytime continence was achieved by all patients 6 months after surgery. A greater number of patients in group II demonstrated temporary nocturnal leakage than in group I, but this difference was not statistically significant (P = .09). The authors conclude that both methods of IPAA are equally effective in preserving normal sphincter function. In patients with severe rectal inflammation, extrarectal dissection with stapled anastomosis may obviate the need for extended preoperative hyperalimentation or subtotal colectomy, but may carry a small increased risk of recurrent anorectal inflammation. The long-term risk of dysplasia is unknown, but may be slightly higher after extrarectal dissection with stapled anastomosis. Further study of both methods of IPAA is recommended.
