Laparoscopic repair of a Spigelian hernia using an expanded polytetrafluoroethylene (ePTFE) mesh.

Spigelian hernia are rare and difficult to diagnose. The use of the laparoscope has simplified the diagnosis, clarified its localization, and facilitated the subsequent repair of these hernias. We describe a Spigelian hernia treated with an expanded polytetrafluoroethylene (ePTFE) patch that was applied as an peritoneal onlay. We added coagulation of the hernial sac to the standard technique in order to prevent formation of a seroma, a frequent complication of the use of an ePTFE patch.
