Purpose: Despite the fact that the laparoscopic-assisted endorectal pull-through (LAEPT) for Hirschsprung's disease (HD) was introduced over 20 years ago, published outcomes in older children and adolescent are lacking. To address this, we studied the long-term results of LATEP for rectosigmoid HD in patients above 5 years of age. Materials and Methods: A retrospective review was conducted on all nonsyndromic patients above 5 years of age and who underwent one-stage LAEPT for rectosigmoid HD between January 2002 and December 2017. Late Hirschsprung-associated enterocolitis (HAEC) was defined as HAEC occurring 1 year after the pull-through operation. Postoperative bowel function was assessed using the Krickenbeck classification. Results: Forty-one patients (37 males and 4 females) were included in this study with a median follow-up of 9.0 years. The median age at surgery was 55 days. Two patients had anastomotic leakage. No patient had late HAEC, rectal prolapse, anastomotic stricture, or intestinal obstruction. According to the Krickenbeck classification, all patients had voluntary bowel movements without constipation. Overall, 65.8% of patients had no soiling. However, on subgroup analysis, only 45.4% of patients younger than 11 years of age had no soiling compared with 89.5% in patients at or older than 11 years of age (P = .003). Conclusions: Our results showed that LAEPT for rectosigmoid HD was a safe procedure. Nearly 90% of patients had normal bowel function by puberty. Further studies are needed to address the problem of soiling in patients younger than 11 years of age.
