Abstract
We report a case of left paraduodenal hernia (LPDH) that was preoperatively diagnosed by computed tomography (CT) and upper gastrointestinal series (UGI) and underwent an elective surgery. A 50-year-old man was admitted to the hospital because of left upper abdominal pain and postprandial vomiting as “unknown subileus”. There was slight tenderness in the left upper quadrant of abdomen. CT showed the looped small intestine with converging mesenteric vessels in the left upper abdomen. Both before and after intestinal obstructions were relieved by conservative treatment. UGI demonstrated the looped jejunum associated with stenosis of its proximal and distal ends. These findings were considered to represent LPDH. Elective surgery revealed a hernia sac with the hilus 4cm in diameter to the ligament of Treitz. The hernia contained the 40cm-long, non-ischemic jejunum. This patient underwent closure of the hernia hilus. In patients with intestinal obstruction, differential diagnoses should include LPDH. It may show characteristic CT and UGI findings.
