Comparative Analysis of Laparoscopic and Robotic Transperitoneal Adrenalectomy Performed at a Single Institution.

Background and Objectives: Laparoscopic adrenalectomy (LA) is the standard surgical approach for adrenalectomy. At present, robotic adrenalectomy (RA) has been introduced at various hospitals. This study evaluated our initial experience with robotic adrenalectomy compared with conventional laparoscopic adrenalectomy. Materials and Methods: From October 2018 to March 2022, 56 adrenalectomies were performed by a single endocrine surgeon. Thirty-two patients underwent LA (LA group), and twenty-four patients underwent RA (RA group). Results: Patients in the RA group were significantly younger than those in the LA group (48.6 ± 9.7 years vs. 55.1 ± 11.4 years, p = 0.013). The RA group had a shorter operation time than the LA group (76.1 ± 28.2 min vs. 118.0 ± 54.3 min, p < 0.001). The length of hospital stay and postoperative pain level between the two groups were similar. There were no complications in the RA group. There was no significant difference in the pathologic diagnosis between the two groups. The cost of surgery was significantly higher in the RA group than in the LA group (5288.5 US dollars vs. 441.5 ± 136.8 US dollars, p < 0.001). Conclusions: In our initial experience, RA showed a shorter operation time than LA and no complications. RA could be a viable alternative surgical option for adrenalectomy, notwithstanding its higher cost.
