title: Gallstone-related abdominal cystic mass presenting 6 years after laparoscopic cholecystectomy: A case report.
abstract: BACKGROUND
  Although gallbladder perforation and gallstones spillage are common complications during laparoscopic cholecystectomy (LC), clinically significant complications resulting from stones left in the peritoneum are extremely uncommon. We report a rare case of spilled gallstones complication with a late and uncharacteristic presentation.
  
  
  METHODS
  A 44-year-old Caucasian female presented with a complaint of a mass in the right upper quadrant associated with a cramping pain for the last 6 months. Her past surgical history included a laparoscopic cholecystectomy performed six years ago. Abdominal computed tomography demonstrated an intra-abdominal cystic mass. On open exploration, a cystic mass adhered to the abdominal wall was excised containing two gallstones. The patient tolerated the procedure well and had uneventful postoperative recovery.
  
  
  CONCLUSIONS
  Although unretrieved gallstones are considered harmless, serious complications can occur early or late. The most frequent complication is the formation of abscesses in different locations.
  
  
  CONCLUSIONS
  The diagnosis of gallstone abscess after years of LC is usually a diagnostic challenge. Obtaining a comprehensive past surgical history still plays an important role in the assessment of patients presenting with unusual findings.
