Abstract
We present a case of interparietal hernia, a rare subtype of inguinal hernia, diagnosed and repaired laparoscopically.
A 65-year-old man complaining of nausea and vomiting was admitted to our hospital with a diagnosis of intestinal obstruction. Computed tomography (CT) scan showed a dilated small intestine presented to the inside of the inferior epigastric vessels and compressed the testicular vessels and umbilical artery dorsalward. Operation was performed on suspicion of internal hernia or strangulated ileus due to an abnormal band.
On laparoscopy, bloody ascites and redness of the small intestine were observed. Incarceration had been released. A hernia sac was recognized on the inner back side of the internal inguinal ring, and incarceration of the small intestine to the space was diagnosed. Dissection of the preperitoneal space disclosed the hernia sac situating between the transverse fascia and peritoneum. From these findings, interparietal hernia was diagnosed. The hernia sac was resected, and the hernia was repaired with mesh in the preperitoneal space by transabdominal preperitoneal repair method.
