Gallbladder perforation during laparoscopic cholecystectomy (LC) with spillage of bile and gallstones occurs frequently, but clinical sequelae caused by dropped gallstones are uncommon. We present a case of subhepatic and right-back abscess formation due to spilled gallstones occurring two years after LC, which were successfully removed using a percutaneous method as a minimally invasive technique. The patient firstly visited a primary care physician with right-back mass that was increasing in size and becoming symptomatic, then underwent incision and drainage. He was referred to our hospital and the subhepatic and right-back inflammatory mass containing spilled gallstones was revealed by computed tomography. Under fluoroscopic control, a percutaneous drainage catheter was placed within the abscess and pus was aspirated. The spilled gallstones were successfully retrieved with basket forceps, thereafter. The patient was discharged without significant complications on the 9th day after the percutaneous stone removal.
