[Transanal pull-through for Hirschsprung disease in new borns and infants].

OBJECTIVE

To introduce the transanal pull-through for congenital Hirschsprung's disease in new borns and infants.

METHODS

The 43 cases on whom were performed transanal pull-through for Hirschsprung's disease were reviewed. The ages of the patients were 14 days-12 months. The technique included a rectal mucosectomy at the proximal to the dentate line, separating mucosas from rectal wall to the peritoneal reflection. The part of rectal muscularis below the peritoneal was resected posteriorly. An anastomosis was made between the pull-through ganglionic colon and anus.

RESULTS

In the 43 cases the operations were easily accomplished by excising the injured intestine. The blood lost was small. The patients took food after 1-2 days of operation. discharged 5-7 days later. No retention of urine and no infection of incision wound were observed. Total follow up lasted 3-9 months. Defecation was normal, and there was no stricture of anus. Only 2 cases had soiling by chance.

CONCLUSION

Simple transanal pull-through is an ideal type of operation for congenital Hirschsprung's disease in new borns and infants. It is an easy operation, with less injury, quick recovery and rare complication.
