Abstract
A 72-year-old man underwent colectomy for colon cancer 4 years previously, and he was scheduled to undergo hepatectomy for a suspected liver metastasis. This patient required surgery for a bleeding adrenal gland, but while he was under general anesthesia for the use of a soft coagulation system to repair the bleeding adrenal gland, he developed hypertension and tachycardia. As soon as we stopped hemostatic therapy, his blood pressure stabilized, and he recovered from anesthesia without further complications. All the tested adrenal hormones in the blood and urine were within the normal range, and abdominal CT and MIBG scintigraphy did not reveal a tumor in the adrenal gland postoperatively. Currently, the patient is alive without recurrence, and his blood pressure is stable. This case suggests that treatment of the adrenal gland with the use of soft coagulation should be approached with caution.
