Twenty-five years' experience with Hirschsprung's disease.
Sixty-three patients with biopsy-proven Hirschsprung's disease were diagnosed at LeBonheur Children's Medical Center, Memphis, TN between 1955 and 1980. Fifty-eight of these patients had pull-through procedures performed by three similarly trained pediatric surgeons. The follow-up was 100 percent, averaging 8 years from initial diagnosis. Demographics, surgical procedures performed, and complications are reviewed. Significant findings are (1) anastomotic strictures occurred most frequently when the level of aganglionosis was at the sigmoid colon; (2) postoperative encopresis was most likely when the endorectal pull-through procedures were performed before the age of 10 months; and (3) with selective use of colostomies or enterostomies performed prior to the pull-through procedure, the incidence of enterocolitis was low, with 0% mortality. On the basis of these findings, we recommend that, when the most proximal level of aganglionosis is the sigmoid colon, it is important to critically inspect the angulation of mesenteric blood vessels and viability of the splenic flexure pull-through colon segment to prevent ischemia and therefore anastomotic strictures. The endorectal pull-through procedure should be delayed until after 10 months of age. Infants with Hirschsprung's disease should have a colostomy or enterostomy prior to a pull-through procedure. Patients diagnosed at 10 months of age or more, who have not had earlier bouts of enterocolitis, are not low percentile weight, and are without signs of severe obstruction, are candidates for pull-through without a prior fecal diversion procedure.
