OBJECTIVES: To report the indications, technique, and results in patients with primary hyperaldosteronism due to aldosterone-producing adrenal adenoma treated by laparoscopic partial adrenalectomy. Laparoscopy has become the technique of choice in adrenal surgery, but adrenalectomy is the standard procedure. Only a few studies have reported on partial adrenalectomy, and the indications and technique have not yet been clearly defined. METHODS: From June 1995 to December 2001, 13 patients presented with hyperaldosteronism and a single adrenal adenoma (Conn's syndrome) and were treated with laparoscopic partial adrenalectomy. The mean age was 60 years, and the average tumor size was 2.1 cm in diameter. A transperitoneal approach was used in all patients, tumors were resected with safety margins by endoshears, and hemostasis was achieved by bipolar coagulation and finally by sealing with fibrin glue. RESULTS: All procedures were finished laparoscopically, and no conversion was necessary. No major intraoperative or postoperative complication was observed. The histologic examination showed adenomas with negative surgical margins in all cases. Postoperative computed tomography revealed a normal blood supply for the remaining adrenal tissue. Blood pressure and aldosterone levels were unremarkable at follow-up, and no local recurrence was observed. CONCLUSIONS: Laparoscopic partial adrenalectomy for aldosterone-producing adenomas is a minimally invasive procedure with a low complication rate. It provides the benefit of retaining functional tissue on the side of the affected adrenal gland. Therefore, we recommend laparoscopic partial adrenalectomy for patients with small, potentially benign, tumors of the adrenal gland, even with a healthy contralateral adrenal gland.
