Intestinal Obstruction Due to an Incarcerated Obturator Hernia: A Case Report and Review of the Literature.

An obturator hernia (OH) is a rare form of pelvic hernia in which the abdominal contents protrude through the obturator canal. Malnourished, frail, and multiparous elderly females are at risk of an OH. Preoperative diagnosis of obturator hernia is challenging because of non-specific symptoms. Most of the cases of OH reported in the literature are diagnosed during a laparotomy for acute intestinal obstruction. However, a contrast-enhanced computed tomography (CECT) scan of the abdomen is the best diagnostic investigation for OH. The morbidity and mortality are high because of the associated complications. We report a case of an obturator hernia in a 79-year-old cachectic female with features of acute intestinal obstruction and the usefulness of a CT scan in the preoperative diagnosis. Early diagnosis and treatment are the keys to preventing disastrous complications.
