Endorectal pull-through with conservation of the rectal mucosa: experimental study

The present experimental work was designed to study an abdominoanal pull-through technique, with conservation of rectal mucosa. Continence was evaluated from clinical, radiologic, and histopathologic standpoints. The animals defecated normally. A good retention of barium was seen in the radiologic enema. On the reexploration of the animals, we found a distal dehiscence with elevation of the intussuscepted stump towards the rectum in all. A reepithelization process of serosa of the intussuscepted segment was noted.
