Arteriographic findings in congenital transmesenteric internal hernia

Congenital transmesenteric internal hernia - A case report with literature review

Congenital transmesenteric internal hernia is a rare condition presenting as recurrent pain abdomen or acute intestinal obstruction. Preoperative diagnosis of internal hernia is very rare. Early intervention and surgical correction goes a long way in preventing high morbidity and mortality associated with cases of internal hernia. We report a case of congenital transmesenteric intra-abdominal hernia presented as acute abdomen with timely surgical intervention in the form of emergency laparotomy with untwisting and reduction of small bowel herniated through large congenital terminal ileal mesenteric defect and repair of mesenteric defect.

Internal hernia: an increasingly common cause of small bowel obstruction

Internal hernia is an uncommon cause of small bowel obstruction that may be increasing in frequency. Because the clinical diagnosis of internal hernia is difficult, imaging studies such as computed tomography (CT) and small bowel follow through play an important role. Transmesenteric hernia is the most common type and is usually related to prior abdominal surgery, especially with creation of a Roux-en-Y anastomosis (eg, liver transplantation, gastric bypass). CT may allow confident diagnosis in most cases. In this article, we review the clinical and imaging findings of internal hernia based on our experience with 54 cases of surgically proven internal hernias including 45 transmesenteric, 6 paraduodenal, and 3 omental hernias, 39 of which had imaging studies available for review.

The occurrence of a strangulated ileus due to a traumatic transmesenteric hernia: report of a case

We report herein the case of a 6-year-old boy in whom a strangulated ileus was caused by a traumatic transmesenteric hernia. The boy had fallen from his bicycle and suffered a severe blow to the abdomen. Abdominal pain and vomiting developed 10 h after the accident and he was admitted to our hospital. Abdominal ultrasonogram and computed tomogram demonstrated ascites, intestinal wall thickening with fluid, and an engorged radiating mesenteric vasculature. Thus, an emergency laparotomy was performed which revealed bloody ascites, a strangulated ileus, and torsion with a transmesenteric hernia. The necrotic intestine was resected and an anastomosis was performed. Macroscopic and microscopic findings revealed a traumatic mesenteric rent. The unusual presentation of this case is discussed.
