Abstract
A 37-year- old man presented with acute-onset abdominal pain and nausea. He was referred to our hospital with the diagnosis of ileus. Abdominal computed tomography showed a positive closed loop sign of the small intestine. Since we suspected strangulated ileus caused by an internal hernia, emergency laparoscopic surgery was performed. Laparoscopy revealed ileus due to transomental herniation. About a 30-cm segment of the small intestine had herniated through a hiatus of the greater omentum. Because the herniated small intestine showed no dark red discoloration, it was not resected. After the herniation was laparoscopically released, the greater omentum was cut and the hiatus of the greater omentum was opened. We therefore conclude that laparoscopic surgery is useful for the diagnosis of ileus caused by transomental herniation.
