Reoperations in Hirschsprung disease.

BACKGROUND: We sought to identify causes of preventable complications related to operations for Hirschsprung disease.

METHODS: We reviewed the cases of 51 patients with Hirschsprung disease who underwent a primary procedure elsewhere, had a complication, and were referred for reoperation.

RESULTS: Thirty-five patients had 1 failed operation, 10 had 2, and 6 had 3. Initial operations were Soave (20), Duhamel (15), Swenson (5), transanal endorectal (4), myectomy (3), unknown (3), and laparoscopic Swenson (1). Thirty-one patients presented with a stoma. Patients without a stoma (20) had fecal impaction (8), recurrent enterocolitis (6), and fecal incontinence (6). None had both enterocolitis and incontinence. Reoperation was performed posterior sagittally (40) or transanally (5). Indications included stricture (21), megarectal Duhamel pouches (12), fistulae (11 [8 rectocutaneous, 2 rectourethral, and 1 rectovaginal]), pouchitis (2), and retained aganglionic bowel (8). After reoperation, 14 were continent, 11 had a stoma (8 permanent), 6 had voluntary bowel movements but soiled occasionally, 6 received rectal irrigations to avoid enterocolitis, 6 were incontinent but clean with bowel management, and 2 were lost to follow-up.

CONCLUSION: Stricture, megarectal pouch, fistula, and retained aganglionic bowel are preventable complications. Enterocolitis is partially preventable but can occur after a technically correct procedure. Fecal incontinence is a preventable complication likely because of anal canal damage.
