Laparoscopic adrenalectomy: lessons learned from an initial series of 100 patients

Abstract

Background

Laparoscopic adrenalectomy is considered the gold standard for the surgical treatment of adrenal disorders in most centers. This study analyzes the authors’ experience using the lateral intraperitoneal approach with the first 100 patients. In addition to analyzing the authors’ experience, this article aims to contrast it with some published series as an internal quality control.

Methods

In a 10-year period, 138 laparoscopic adrenalectomies were performed for 100 patients. Demographics, surgical results, complications, and long-term outcomes were analyzed.

Results

The participants comprised 69 women and 31 men with a mean age of 37 years. The procedures included 24 right, 38 left, and 38 bilateral adrenalectomies. The indications for surgery were Cushing’s disease for 33 patients, pheochromocytoma (4 bilateral) for 23 patients, Cushing’s syndrome for 18 patients, Conn’s syndrome for 16 patients, and incidentaloma for 10 patients. Five procedures were converted to open surgery. Two patients with pheochromocytoma required intraoperative blood transfusion. The mean operative time was 174 min for unilateral adrenalectomies and 302 min for the bilateral procedures. The mean hospital stay was 5 days. Surgical morbidity included an abdominal wall hematoma, a small pneumothorax, and intraabominal bleeding in one patient that required reexploration. There were three operative mortalities not related to the technique. The long-term results showed control of hypercortisolism in all the patients with Cushing’s disease and 82% of the patients with pheochromocytoma. Most of the patients with Conn’s syndrome (91.4%) became normotensive after surgery.

Conclusions

Laparoscopic adrenalectomy is safe and effective. The complications are mild, and mortality is related more to the patient’s condition than to the surgical technique.
