To map existence of the preperitoneal fatty plug and hernia in obtorator canal.

Prospective study and review of literature.

Institute of Anatomy of the 1st Faculty of Medicine, Charles University, Prague.

Subject and method:
We have dissected lesser pelvises of ten formalin embalmed female cadavers with focus on possible anatomical variations such as obturator hernia or preperitoneal fatty plug.

In six cases we have found formation reponable back to lesser pelvis, which could be described as preperitoneal fatty plug (which could be considered as type I of obturator hernia). Photos were taken and the formation was sent for histological exam to confirm whether peritoneum was present at the surface. Histological exam was carried out by standard procedure with hematoxylin-eosin staining.

In six female bodies we have witnessed preperitoneal fatty plug five times on the left and three times on the right side.

Key word:
anatomy, obturator hernia, preperitoneal fatty plug.
