Hirschsprung Transitional Zone: Considerations for Re-doing a Pull-through Procedure

Hirschsprung disease is a congenital condition that causes intestinal obstruction in the first days or weeks of life. Surgical treatment known as a pull-through procedure can connect the healthy part of the intestine to the rectum. While it is critically important to identify the histological transition zone of ganglion cells - where the aganglionic cells stop and the normoganglionic cells start - in the intestine before performing the procedure, it is also important to understand how they appear after the procedure.
In this video, Luis De la Torre, MD, Assistant Director of the International Center for Colorectal and Urogenital Care, explains the importance of understanding the histological transition zone after surgery. Not fully understanding how these areas look and test after surgery can lead to unnecessary reoperations and fecal incontinence. Watch the video to hear Dr. De la Torre explain his studies on postoperative functional results following a pull-through procedure and his current recommendations for re-doing a pull-through procedure for children with Hirschsprung disease.
