Chilaiditi syndrome is assosiated with hepatodiaphragmatic interposition of the colon and the small intestines. We anesthetized 2 patients with Chilaiditi syndrome. A 62-year-old woman with interposition of the intestine was scheduled for right femoral fibrosarcoma resection. She had been medicated for schizophrenia. Total intravenous anesthesia was induced and maintained. Another patient an 81-year-old man with interposition of the colon, was scheduled for transurethral resection of a bladder tumor. He was anesthetized with spinal anesthesia. In both cases, there was no cardiovascular complication or digestive disorder during the perioperative period.
