Computed tomographic diagnosis of obturator hernia and its surgical management: a case series

The obturator hernia is a rare type of hernia which usually presents in thin, elderly women. The preoperative diagnosis is typically difficult, with non-specific signs and symptoms which result in a delay in the diagnosis. It can also be an incidental finding at exploratory laparotomy for a patient with intestinal obstruction. The treatment is surgical. A series of four females with obturator hernia is presented. All patients presented with a history of intestinal obstruction and the hernia was diagnosed preoperatively by computed tomography. All patients underwent a preperitoneal mesh repair with a favourable outcome. The diagnosis and the surgical approach are discussed.
