Role of transanal endorectal pull-through in complicated Hirschsprung's disease: experience in 18 patients.
OBJECTIVE
In Hirschsprung's disease (HD) redo pull-through (PT) is indicated for anastomotic complications and for persistent aganglionosis after previous definitive surgery. This study was undertaken to evaluate the role of transanal approach to redo PT procedure in the management of complicated cases of HD over the last 7 years.


METHODS
Between November 1998 and September 2005, 225 patients with HD were operated using the transanal endorectal PT (TEPT) approach. Eighteen patients had a redo PT owing to persistent aganglionosis. The present study evaluates the role of TEPT approach in patients with persistent aganglionosis (n = 18). Three patients needed a colostomy (n = 2) or ileostomy (n = 1) before the final operation. All the 18 patients underwent transanal mobilization (TEPT) of the colon. Six patients required additional mobilization of the proximal colon (n = 4) and the ileum (n = 2) during the redo PT operation.


RESULTS
Median follow-up was 43 months (range, 3-72 months). Sixteen patients have had a good outcome with stool pattern 1 to 4 times daily. One patient had obstructive symptoms for 4 months postoperatively but then settled. One patient has occasional soiling.


CONCLUSIONS
In this series, TEPT and posterior midline split of the muscle cuff were used with good results. This has the advantage of avoiding injury to the pelvic muscles and nerves. The TEPT approach is combined with transabdominal mobilization of the intestine depending on the length of the aganglionic segment. The outcome has been favorable, but long-term follow-up is necessary for full assessment of those patients.
