Background: Laparoscopic adrenalectomy is widely used for treating various adrenal tumors. Posterior retroperitoneoscopic adrenalectomy was introduced after transperitoneal laparoscopic adrenalectomy. The comparability and superiority of posterior retroperitoneoscopic adrenalectomy have been widely investigated. We aimed to compare the outcomes of posterior retroperitoneoscopic adrenalectomy and transperitoneal laparoscopic adrenalectomy using 10 years' data. The changes in outcomes over time were also analyzed.

Methods: This was a retrospective observational study. A total of 505 patients who underwent laparoscopic adrenalectomy between 2009 and 2018 were included. The patients were divided into two groups: transperitoneal (n=114) and retroperitoneal (n=391) groups. Patients who underwent posterior retroperitoneoscopic adrenalectomy were further classified into sub-groups (sub-group 1: 2009-2012; sub-group 2: 2013-2015; and sub-group 3: 2016-2018) based on time periods. Clinicopathological factors and postoperative outcomes were retrospectively reviewed and analyzed.

Results: The retroperitoneal group showed significantly shorter operation time, diet initiation time, and hospital stay compared to the transperitoneal group (P=0.000, 0.000 and 0.000, respectively). Analgesics were used less frequently in the retroperitoneal group than in the transperitoneal group (P=0.048). In the retroperitoneal group, the time to postoperative diet initiation shortened over time (P=0.000).

Conclusions: Posterior retroperitoneoscopic adrenalectomy is a favorable surgical method that results in patient outcomes that are comparable to those of conventional transperitoneal laparoscopic adrenalectomy, without compromising patient safety.
