Obturator hernia and the elderly.

An 84-year-old woman with a history of weight loss, anorexia and episodic vomiting was admitted to hospital where she died soon afterwards. Her diagnosis was acute renal injury due to dehydration and malnutrition. At autopsy the body was cachectic with a small intestinal obstruction due to herniation through a defect at the anterolateral aspect of the obturator foramen. A poorly differentiated adenocarcinoma of the gastroesophageal junction was also identified with small peripheral pulmonary thromboemboli. Death was due to small bowel obstruction from a left obturator hernia with scattered peripheral pulmonary thromboemboli complicating cachexia due to gastroesophageal adenocarcinoma. Obturator hernias are called the "little old lady's hernia" and occur mainly in elderly, multiparous and malnourished women. The broader female pelvis and wider obturator canal with laxity of ligaments and loss of preperitoneal adipose tissue padding around the canal predispose to herniation. This rare hernia is often first identified at autopsy.
