To explore the safety and clinical efficacy of robot-assisted laparoscopic adrenalectomy retroperitoneum and transperitoneal.

A retrospective analysis was made of the clinical data of 39 patients with adrenal adenoma treated by robotic surgery via retroperitoneal and transperitoneal approaches in Beijing Anzhen Hospital from Jan. 2017 to Dec. 2018. Among them, 16 patients underwent transperitoneal approach and 23 patients underwent retroperitoneal approach. The clinical data of operation time, intraoperative blood lose, hospitalization days and post-operative hospitalization days were compared between the two groups.

The operation time was(142±28)min and(107±26)min, respectively, with statistic differences between retroperitoneal and transperitoneal approach (P<0.01). The establishment of pneumoperitoneum time was(25±6)min and(19±3)min, respectively, with statistic differences between retroperitoneal and transperitoneal approach (P<0.01). The post-operative hospitalization days were(8±2)d and(7±1)d respectively, with statistic differences between retroperitoneal and transperitoneal approach (P=0.009). There were no statistic differences in intraoperative bleeding lose and average hospitalization day between the two groups (P>0.05).

For robot-assisted laparoscopic adrenalectomy, the retroperitoneal approach has the advantages of shorter operation time, less trauma and faster recovery than the transperitoneal approach.
