Occlusive Syndrome by Internal Transmesosigmoid Hernia: A Case Report and Review of the Literature

Internal transmesosigmoid is a rare condition that can cause unusual small bowel obstruction. We report an 80-year-old male patient presenting with acute intestinal obstruction due to a transmesosigmoid hernia. The patient was operated on for bladder lithiasis 6 years ago. Auscultation revealed intestinal borborygmus, and a CT scan showed sigmoid volvulus in a dolichocolon. The diagnosis of acute intestinal obstruction was made, and an emergency laparotomy was indicated. Because of the high risk of strangulation with a transmesosigmoid hernia, it is mandatory to timely and periodically reassess. Early surgical intervention is crucial to reduce mortality.
