Clinical manifestations of lost gallstones after laparoscopic cholecystectomy: a case report with review of the literature.

Laparoscopic cholecystectomy has become the preferred treatment for patients with symptomatic gallstones. During this procedure, perforation of the gallbladder with spillage of stones into the peritoneal cavity is not uncommon. Finding and removing all of the spilled gallstones can be laborious and is often avoided. Left in the peritoneal cavity, however, the stones may lead to intraperitoneal abscess formation, which may require a second procedure. We report here on a patient with an intraperitoneal abscess located between the right liver lobe and the anterior abdominal wall, which contained a large gallstone (4 cm3), found 3 months after an undetected stone spillage during laparoscopic cholecystectomy. Healing was achieved after conventional laparotomy, removal of the gallstone, and surgical drainage of the abscess cavity. The review of the literature emphasizes the clinical manifestations of this rare laparoscopic complication.
