A 55-year-old woman underwent laparoscopic cholecystectomy (LC) with a diagnosis of cholelithiasis at another hospital. She suffered from biloma 1 month postoperatively. About 16 months after operation, she visited our hospital because of right hypochondralgia. Abdominal radiography showed numerous metallic clips in the right upper abdomen. Abdominal computed tomography (CT) showed a low density area 5cm in diameter including one clip under the right lobe of the liver. Diagnosis of intraperitoneal abscess associated with a migrated clip after LC was made and ultrasonically guided percutaneous abscess drainage was done. A radiocontrast study through a drainage tube showed the intraperitoneal abscess including 1 clip. Pseudomonas aeruginosa was detected in a culture of pus collected through the drain. She was treated with drainage and antibiotics. Follow-up CT showed the abscess has shrunk 33 days after admission. The drainage tube was removed and she was discharged and remains disease-free and well 10 months later. No cases of intraperitoneal abscess associated with migrated clips after LC have been previously reported in the literature. This case suggests the need for awareness of probable latent complications following LC.
