Intraoperative hypothermia occurs frequently, but hyperthermia is relatively rare during general anesthesia. We experienced a case of hyperthermia during living donor liver transplantation that appeared to be significantly associated with biliary obstruction. A 65-year-old male patient was diagnosed with intrahepatic cholangiocarcinoma, and living donor liver transplantation was planned after confirmation of no metastasis via intraoperative frozen biopsy. Following resection of a segment of common bile duct for frozen biopsy, the surgeon clamped the common bile duct, and the patient's body temperature increased gradually to 39.5°C. As the congested bile was drained, the body temperature decreased to the normal range. This case report suggests that when a patient develops unexplained hyperthermia during hepatobiliary surgery or in a chance of biliary obstruction, clinicians should consider bile congestion as a possible reason for hyperthermia.
