Laparoscopic Adrenalectomy for Pheochromocytoma Versus Other Surgical Indications

Abstract

Objective: Laparoscopic adrenalectomy is widely recognized as the preferred technique for surgical removal of adrenal masses. This study aimed to evaluate the outcomes of consecutive laparoscopic adrenalectomies performed at a high-volume referral center and compare operative results for pheochromocytomas with that of other adrenal diseases. Materials and methods: We retrospectively reviewed a single surgeon's experience with laparoscopic adrenalectomy performed between July 2002 and June 2007. Patient records were analyzed in regards to demographics, pathology diagnoses, operative time, postoperative complications, tumor size, hospital stay, among others. Results: Seventy-two consecutive laparoscopic adrenalectomies were performed on 70 patients, including 2 bilateral adrenalectomies and one partial adrenalectomy. Surgical indications included pheochromocytoma (n=11), aldosteronoma (n=26), malignant adrenal disease (n=4), nonfunctioning adenomas (n=17), Cushing's disease (n=6), and other adrenal disease (n=8). No mortality was observed. Perioperative complications occurred in 7 cases (9.7%). When a comparison between pathological diagnosis groups was made, no statistical differences were seen between pheochromocytomas and other adrenal neoplasms with respect to estimated blood loss, open conversion rate, length of stay, preoperative and postoperative hemoglobin values, blood transfusion rates, perioperative complication occurrence, tumor size, and ASA class. Conclusion: Laparoscopic adrenalectomy is a safe and appropriate surgical technique for most adrenal lesions, including pheochromocytomas.
