Anesthesia record of the first (A) and the second surgery (B). A Periodic blood pressure fluctuations occurred after tracheal intubation, lasted approximately for 150 min, and subsided at the end of laparoscopic surgery. Levels of adrenaline, noradrenaline, and dopamine were 3.22, 1.98, and 0.02 ng/ml at the point of [1], 6.32, 3.12, and 0.02 ng/ml [2] and 0.36, 0.47, and 0.02 ng/ml [3], respectively. B Periodic blood pressure fluctuations occurred after anesthesia induction, lasted approximately for 200 min, and disappeared after pheochromocytoma resection. The fluctuations were approximately 10 min apart, and the degree was smaller than that of the first surgery
