Objectives: We compared two different approaches to right laparoscopic transperitoneal adrenalectomy for large tumors (>5 cm): the anterior transperitoneal (AT) and lateral transperitoneal (LT) approaches. Methods: 40 patients with a right large adrenal mass >5 cm underwent right adrenalectomy: 20 patients underwent the AT procedure and 20 patients the LT procedure. Preoperative characteristics were similar for both groups: mean tumor size for the AT and LT groups was 6.52 cm (range 5.2–8.5) and 6.59 cm (range 5.4–8.1), respectively. Mean patient’s age was 53 years (23–75 in the AT group and 20–77 in the LT group). AT and LT approaches were compared in terms of operative time, intraoperative blood loss, time to first oral intake and postoperative convalescence. Results: No difference was found between two groups in terms of estimated blood (100 ml for the AT group and 105.3 ml for the LT group), time to first oral intake (2.0 days for both groups) and convalescence (3.5 and 3 days, respectively). The mean operative times of the AT and LT procedures were 75.25 and 84.75 min, respectively: this difference was statistically significant at the Student’s t test (p = 0.0423). Conclusions: Both approaches proved to be safe and minimally invasive. We believe that the shorter operative time of AT procedures was related to the better visibility of familiar anatomic landmarks, easier access to the vessels and a larger operative field. For these reasons, we prefer the AT approach in the management of large adrenal masses.
