Abstract
A 56-year-old man was performed a laparoscopic cholecystectomy for cholecystolithiasis. Tazobactam/piperacillin was administered against epigastralgia and fever persisting since the postoperative day (POD) 3, however, no symptomatic remission was gained. Abdominal computed tomography and abdominal ultrasonography demonstrated an infected liver cyst on POD 10. Ultrasound guided percutaneous transhepatic abscess drainage (PTAD) was performed and 50 ml of white purulent discharge was drained. Then the drainage tube was replaced. A bacterial culture test on the cystic fluid and blood showed no significant pathogenic growth. Symptoms improved immediately after PTAD, and the patient was discharged from the hospital on POD 24. Liver cysts are commonly encountered in daily treatment. Although most cases are asymptomatic, there are occasional reports of infection. It was etiologically inferred that surgical manipulation of the infected gallbladder might pass the causative pathogen to the hepatic cyst through the peripheral and portal veins. We have to consider the risk of causing infection to the liver cyst in patients undergone a cholecystectomy for cholecystitis.
