Introduction
Laparoscopic adrenalectomy has become the gold standard of surgical treatment for benign adrenal masses. Two alternative surgical approaches are currently advocated: the lateral transperitoneal approach (LTA) and the posterior retroperitoneal approach (PRA). Several randomized trials have compared LTA to PRA, but most of them included small numbers of patients or had stringent inclusion criteria.

Aim
To compare clinical results of LTA and PRA endoscopic adrenalectomies for tumors < 8 cm with wide inclusion criteria.

Material and methods
We randomized 77 patients to either LTA (n = 33) or PRA (n = 44). The groups were comparable in terms of age, gender proportions, body mass index, tumor size, clinical and pathological diagnosis. We analyzed duration of surgery, intraoperative blood loss, postoperative pain, length of hospital stay and postoperative morbidity.

Results
The follow-up concerned 98.8% of patients and was on average 28 (8–47) months long. There were no conversions. We identified significantly lower intensity of pain assessed 24 h after surgery in the PRA group (3.4 ±1), as compared to LTA (4.2 ±1), with lower prevalence of shoulder pain (2.3% vs. 30.3%, respectively). Postoperative hospital stay was shorter in the PRA (1.14 ±0.4) than in the LTA (1.36 ±0.5) group. Perioperative morbidity concerned 4 patients in each group with pain requiring oral analgesia > 7 days.

Conclusions
To our knowledge this is the largest prospective randomized study comparing LTA to PRA. We demonstrated safety, efficacy and very low morbidity of both techniques. The PRA proved superior to LTA in terms of lower intensity of postoperative pain and shorter hospital stay.
