Primary transanal rectosigmoidectomy for Hirschsprung's disease: Preliminary results in the initial 33 cases.
OBJECTIVE
The authors describe their newly developed technique-primary transanal rectosigmoidectomy for Hirschsprung's disease (HD) and its preliminary results in neonates and infants.


METHODS
Thirty-four consecutive patients (26 boys) with biopsy-proven rectosigmoid HD, aged 18 days to 4 years, underwent this new procedure. Rectal mucosectomy started 1 to 1.5 cm posteriorly and 2 to 3 cm anteriorly proximal to the dentate line. The rectal muscular sleeve below the peritoneal reflection was resected to the level of the striated muscle complex, leaving a shorter muscular cuff, into which a partial internal sphincterotomy was made posteriorly. An oblique anastomosis was constructed between the pull-through ganglionic colon and the anus canal.


RESULTS
The mean time for the operation was 160 minutes, and the average length of bowel resected was 29.5 cm (range, 12.5 to 41 cm). Two children (6.06%, 2 of 33) had 2 to 5 episodes of postoperative enterocolitis (EC). One was cured by rectal irrigation and dilation, and the another by Lynn's myectomy. Eighty-four percent of patients had 1 to 6 bowel movements per day during a 6- to 18-month follow-up period.


CONCLUSIONS
Primary transanal rectosigmoidectomy for HD is logical and associated with excellent early results. A long-term follow-up is required to determine bowel functions. J Pediatr Surg 36:1816-1819.
