Left paraduodenal hernia with chronic abdominal symptoms

A case of left paraduodenal hernia giving chronic abdominal symptoms is presented. For 3 years the patient had had unexplained abdominal pains, the reason for which was not found until a laparotomy was performed. A retrospective review of the x-ray films showed that an internal hernia should have been suspected from the small bowel follow-through and barium enema. The possible existence of an internal hernia in cases of unexplained abdominal pains is emphasized.
