title: Percutaneous removal of retained calculi from the abdomen.
abstract: With rising pressure placed on health service resources minimally invasive techniques requiring only short hospital admissions are increasing in importance. We describe the techniques used to remove calculi from the peritoneal cavity which had been retained after surgery and continued to cause clinical problems. In both cases described the calculi lay within abscess cavities associated with fistulous tracks to the skin. The fistulae were dilated to allow passage of therapeutic radiologic and endoscopic equipment enabling manipulation and subsequent extraction of the stones. In both cases removal of the calculi allowed complete resolution of the fistulae and the patients made a full clinical recovery. Removal of gallstones which have escaped into the peritoneum at laparoscopic cholecystectomy leading to sepsis has been described; we describe the novel management of a patient in whom extraction had already been attempted, at another hospital, without success. Removal of an appendicolith, described here in another patient, does not appear to have been reported previously.
