title: A previously unmentioned surgical observation in the treatment of intussusception.
abstract: Intussusception is one of the most common causes of bowel obstruction in infancy which may require surgical treatment. We have recently recognized a pathologically weakened linear area located on the wall of the reduced colon at operation. Thus, a retrospective study was conducted to evaluate the operative and pathological findings of the resected bowel segments for the treatment of intussusception. A pathologically weakened longitudinal linear area was encountered in five patients. This line was strikingly antimesenteric and under the taenia libera. The bowel wall was very thin and effaced on palpation along this whitish line and showed mucosal necrosis, disruption of the muscularis mucosa, and loss of some of the muscular tissue on microscopic examination. The line may result from compression of the inner layers of the bowel wall between the intussusceptum and the noncompliant taenia. Location on the antimesenteric border and under the taenia libera can be explained by local vascular compromise due to the distribution of the terminal arteries of the colon. Thus, the antimesenteric border as well as the mesenteric side should be checked carefully for a longitudinal weakened pressure line. The recognition of such a potentially dangerous weak line on the bowel wall indicates resection.
