BACKGROUND Gallbladder rupture is common in laparoscopic cholecystectomy because the gallbladder is usually in acute or chronic inflammation *** gallstones may sometime be spilled into the peritoneal cavity,resulting in intra-abdominal ab-scess if the gallstones were not *** diagnosis of intra-abdominal ab-scess caused by unretrieved gallstone can usually be correctly identified in the routine imaging studies,such as abdominal ultrasonography or computed tomo-graphy(CT).Here we present a case of abscess formation from unretrieved gall-stone following laparoscopic cholecystectomy,which mimics the imaging findings of metastatic gallbladder *** SUMMARY This case described a 78-year-old man who received laparoscopic cholecystectomy and gallbladder adenocarcinoma was diagnosed after *** adjuvant chemotherapy,the following up abdominal CT showed several small nodules at right upper abdomen and peritoneal carcinomatosis is *** laparoscopic surgery for the excision of seeding tumor was conducted and the pathological diagnosis of the nodules and mass was inflammatory tissues and gallbladder *** Spilled gallstones are a common complication during laparoscopic cholecystectomy and some gallstones fail to be retrieved due to the size or the restricted view of laparoscopic *** spilled gall bladder stones,surgeons may consider regular computerized tomography follow-up,and if necessary,laparoscopic examination can be used as a means of confirming the diagnostic and treatment.
