Reoperative surgery for Hirschsprung's disease.

Most patients who undergo a pull-through procedure for Hirschsprung's disease typically do well. A small number of patients have persistent stooling problems, often manifesting with either constipation or recurrent enterocolitis. A group of these patients will not respond to conservative medical management and may need to undergo another operative procedure. Reoperative surgery for Hirschsprung's disease typically falls into 2 categories, those who require a myectomy and those who need a redo pull-through. This article reviews the workup, indications, and techniques for these procedures and discusses previously published, as well as the authors' outcome, with these 2 procedures.
