APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -During a pull-through procedure, a surgeon removes the part of the large intestine that is missing nerve cells. The surgeon then connects the healthy part of the large intestine to the anus. Surgeons may perform the pull-through procedure as either laparoscopic or open surgery.

Detailed explanation-2: -A pull-through procedure is the definitive operation for Hirschsprung disease, involving the removal of the abnormal segment of bowel that has no nerves, pulling through the normal bowel and connecting it to the anus. Several types of pull-through procedures exist including the Soave, Swenson and Duhamel.

Detailed explanation-3: -The principle of Duhamel’s technique is to exclude the rectum instead of removing it. The proximal normally innervated colon is pulled through a simple cleavage of the rectal space. The colon then appears at the posterior wall of the anal canal.
