Abstract
We report a case of left paraduodenal hernia which was asymptomatic, but diagnosed preoperatively, and was successfully treated by laparoscopic surgery. A 50-year-old man was diagnosed by computed tomography (CT) which was performed for evaluation of a left inguinal hernia, and was the referred to our hospital. Multi-Detector CT showed a part of the small intestine which had herniated into the unnatural space behind the pancreas through the dorsal side of the inferior mesenteric vein (IMV). Laparoscopic findings showed the orifice of the paraduodenal hernia, through which almost all of the small intestine had herniated into the paraduodenal fossa, was made up of IMV, inferior mesenteric artery and the retroperitoneum. After repositioning of the small intestine, the hernia orifice was closed by laparoscopic suturing technique. The left inguinal hernia was repaired by the TAP (transabdominal preperitoneal hernia repair) procedure. There have been 76 cases of paraduodenal hernia reported in the Japanese literature from 2002 to 2011. There were only 2 cases, including ours, that were asymptomatic and diagnosed preoperatively. Among them, our case was considered to be the only one which was treated by laparoscopic surgery.
