title: Transmesosigmoid hernia: case report and review of literature.
abstract: Transmesosigmoid hernia has previously been considered as a rare condition. The clinical symptoms can be nonspecific. Here, we report a case of acute intestinal obstruction because of transmesosigmoid hernia. In addition, after a comprehensive review of PubMed and China National Knowledge Infrastructure, we present a review of 22 cases of transmesosigmoid hernia. We summarize several valuable clinical features that help early recognition of transmesosigmoid hernia. As a result of easy strangulation, in patients without a history of surgery or abdominal inflammation who present with symptoms of progressive or persistent small bowel obstruction (SBO), surgeons should consider the possibility of transmesosigmoid hernia. In addition, based on our data, in patients with SBO because of transmesosigmoid hernia, the defect is usually 2-5 cm in diameter. Furthermore, because of the high risk of strangulation with transmesosigmoid hernia, it is mandatory to reassess the condition timely and periodically when patients receive conservative treatment.
