Purpose: This study aimed to compare the intraoperative and postoperative outcomes between robotic and laparoscopic transperitoneal adrenalectomies.
Methods: In this retrospective study, 93 patients underwent adrenalectomy using 2 surgical modalities: 45 patients underwent adrenalectomy using the da Vinci Xi system (robotic group), and 48 patients using laparoscopic devices (laparoscopic group). We compared the operation time, intraoperative bleeding, and hospital stay according to the surgical modality and tumor characteristics.
Results: There were no significant differences in the operative time (P = 0.827), hospital stay (P = 0.177), and intraoperative bleeding (P = 0.174) between the groups. However, the robotic group showed a lower coefficient of variation in total operative time than that of the laparoscopic group (100.6 ± 23.3 minutes vs. 101.9±32.7 minutes, 0.230 vs. 0.321). When divided into 2 subgroups based on the tumor size (<3 cm and ≥3 cm), the robotic group with a tumor sized >3 cm had a shorter operative time than that of the laparoscopic group (P = 0.032). The robotic group also had fewer cases of intraoperative bleeding (P = 0.034).
Conclusions: Compared to the laparoscopic transperitoneal adrenalectomy, the robotic one achieved a lower deviation in total operative time and showed less bleeding and a shorter operative time, especially for tumors sized >3 cm.
