Laparoscopic resection of pheochromocytoma

The following case report presents the diagnostic procedures, laparoscopic therapy, and postoperative course of a 48-year-old patient with pheochromocytoma. During the previous 15 years, he had occasionally presented with hypertension, intermittent attacks of severe perspiration, and tachycardia; no diagnostic measures were performed at the time. During an ultrasound examination of the abdomen performed due to gastrointestinal complaints, a 5-cm adrenal tumor was discovered incidentally. Further diagnostic procedures then indicated the presence of a pheochromocytoma which was resected laparoscopically. The anesthesia was tolerated well, although isolated systolic blood pressure peaks to 200 mmHg were observed. The laparoscopic tumor resection presented no problems, although identifying the tumor proved to be difficult and resulted in an extended operation time of 4 h and 20 min. The postoperative course was unremarkable. This case report presents our laparoscopic technique and confirms that techniques proven in the "open" resection of a pheochromocytoma can also be utilized in the laparoscopic approach.
