[Retroperitoneal perforation of the gallbladder (author's transl)].

Perforation of the gallbladder into the retroperitoneum is a very rare event. A case report is given of a 71 year old patient suffering from acute cholecystitis. A perforation occurred and a retroperitoneal abscess developed. Cholecystectomy, appendectomy and retroperitoneal drainage were performed, and the patient recovered. A review from the literature is given covering 6 other cases.
