Hirschsprung's disease: revisited.

ABSTRACT

The diagnosis and therapy of Hirschsprung's disease has changed in recent times and a firm diagnosis of the entity can be made pre-operatively by immunohisto-chemistry. There has been a recent trend of switching over from the conventional staged surgical procedures to primary pull-through procedures. In this article the newer concepts referring to its aetiology, pathogenesis, and the current technical advancements like stapler anastomosis, laparoscopic assisted pull-through and single one stage operation without colostomy are discussed along with a brief mention of current concepts in intestinal neuronal dysplasia, enterocolitis and total colonic aganglionosis.
