Section 3. Adrenal: Laparoscopic adrenalectomy for pheochromocytoma: a literature review

Abstract

Laparoscopic adrenalectomy has become the standard treatment for benign adrenal tumors, providing minimal invasiveness and early recovery. In the case of pheochromocytomas, special attention should be paid perioperatively to prevent excessive hypertension or hypotension. The protocol should include sufficient preoperative medication with alpha 1 blockers, early ligation of the adrenal vein, and minimal handling of the tumor itself. A literature review of 227 laparoscopic adrenalectomies for pheochromocytomas revealed that the perioperative data, including the operative time, blood loss, and hemodynamic status, were similar or slightly better in the laparoscopic procedures as compared to the open procedures, although the convalescence period was significantly shorter in the laparoscopic surgery. The majority of surgeons prefer the transperitoneal approach for pheochromocytomas, although some authors use the retroperitoneal approach successfully. A comparison of the perioperative data from laparoscopic surgeries for pheochromocytomas versus those for other adrenal tumors showed that the former had slightly higher demands to complete the procedure safely. In the treatment of familial pheochromocytoma due to multiple endocrine neoplasia type 2 or von Hippel–Lindau disease, a cortical-sparing adrenalectomy can be safely performed laparoscopically. In conclusion, laparoscopic adrenalectomy is the standard for small pheochromocytomas, with a high success rate when the procedure is performed by experienced surgeons.
