Laparoscopic adrenalectomy for adrenal tumors by transperltoneal or retroperltoneal approaches:a report of 41 cases

Abstract

Objective To evaluate the effect of laparoscopic adrenalectomy for adrenal tumors by transperito-neal or retroperitoneal approaches. Methods Atotal of 41 laparoscopic adrenalectomy for adrenal tumor patients were pertormed,inchiding 16 patients by transperitoneal approach and 25 patients by retroperitoneal approach. The tumor size,operative time,intraoperative blood loss, postoperative hospital stay, postoperative ambulatory day and postopera-tive complications were observed. Results Of the 41 cases ,3 cases were transferred to open surgery and the other 38 cases were achieved successful operations. No significant differences( all P>0.05) were found in tumor size,intraop-erative blood loss, postoperative hospital stay, postoperative ambulatory day between the transperitoneal group and ret-roperitoneal group ,but there were significant differences( P<0.05) in operative time and intraoperative blood loss be-tween the two group. Conclusion Both the transperitoneal and retroperitoneal laparoscopic approaches are feasible and safe for adrenal tumors, and the latter has more advantages in operative time, but the operative approach still should be chosen based on the pathological changes,tumor size and position as well as the individual conditions of the patients.
