Duhamel operation for children with distal colonic dysmotility.

PURPOSE

To report outcomes of children with constipation refractory to medical management and manometrically proven distal colonic dysmotility, managed with rectosigmoidectomy followed by Duhamel operation (Duhamel).

METHODS

Children who underwent a Duhamel from 2009 onwards for intractable constipation and left colonic dysmotility were retrospectively reviewed. The primary end point was resolution of constipation, and secondary end point was postoperative complications. Continuous data were median (range).

RESULTS

11 patients (4 males) had Duhamel at 11 years (5-16) with constipation started from 2 years (1-8). Hirschsprung's disease was excluded. All Duhamels were performed with a covering ileostomy: 9 following a Hartmann procedure, one following a previously failed reversal of Hartmann, and one Duhamel performed with a pre-existing ileostomy. All ileostomies were subsequently closed. Median resection length was 22 cm (11-31). Length of stay was 8 days (5-23). Follow-up was 5 years (0.5-7). Age at final review was 15 years (10-18). Resolution of constipation occurred in nine patients (4 required antegrade continence enemas (ACE), 5 with laxative); two had persistent constipation and faecal incontinence despite ACE, ultimately requiring an ileostomy. Two postoperative small bowel obstructions required laparotomy.

CONCLUSION

Duhamel performed in children with manometrically proven distal colonic dysmotility yielded 82% resolution of refractory constipation; half of them subsequently needed ACE.
