Modified Duhamel's Two-Staged Procedure for Hirschsprung's Disease: Further Modifications for Improved Outcomes

AIMS AND OBJECTIVES: We studied the short- and long-term outcomes and quality of life (QOL) in patients undergoing a two-staged modified Duhamel's procedure for Hirschsprung's disease. MATERIALS AND METHODS: Patients who had undergone this modified procedure, with initial Hartmann's procedure based on contrast enema, followed by bowel preparation and low colo-anal anastomosis below the dentate line were included. The patient who underwent this procedure over 10 years with a minimum 2-year follow-up were analysed based on an interview-based questionnaire. RESULTS: Of the 152 patients, 69 responded. Mean age at the time of interview was 7.72 ± 3.04 years with mean follow-up of 4.9 years (2–11 years). Perineal excoriation and soiling was present in 60.9% and 36.2% of patients initially which reduced to 0 and 4.3% by the end of 2 years. In the first 6 months, postoperative period, 15.9% of patients had constipation and 78.2% had altered stool consistency. Good fecal continence score was present in 97.1% of patients in the long term. About 95.4% had good QOL scores. There was no mortality in this series. CONCLUSIONS: Although short-term outcomes showed altered bowel function, soiling, and perineal excoriation, this improved significantly in the long term, with good QOL scores in the majority.
