Delayed peritoneal and retroperitoneal abscesses caused by spilled gallstones: a complication following laparoscopic cholecystectomy.

Many complications following laparoscopic cholecystectomy have been reported. We report a case of delayed peritoneal and retroperitoneal abscesses caused by spilled gallstones from a laparoscopic cholecystectomy performed 1 year earlier. This diagnosis was suggested only at sonography because the aggressive behavior of the lesions containing nonopaque gallstones suggested, by computed-tomography scan, peritoneal metastatic disease.
