There is a lack of data regarding the appropriateness of transperitoneal and retroperitoneal approaches for right-sided laparoscopic adrenalectomy. The aim of this study was to determine whether there is any difference between right-sided transperitoneal laparoscopic adrenalectomy (TLA) and retroperitoneal laparoscopic adrenalectomy (RLA).
Our surgery database was reviewed to identify patients who underwent right-sided laparoscopic adrenalectomy with a retroperitoneal or transperitoneal approach since 2000. Fifty-five patients were enrolled (31 RLA and 24 TLA). Patient characteristics, as well as operative and perioperative details, were compared between the two groups.
There was no difference in patient characteristics between the groups. There was a statistically significant difference (p=0.02) in blood loss (31.7±16.4 vs. 56.9±65.5 ml) between RLA and TLA when the patient's BMI was >26. There was no significant difference in operative time, conversion to open surgery, length of hospitalization, or time to oral intake between the groups.
Right-sided laparoscopic adrenalectomy can be performed safely and effectively via either RLA or TLA. Surgeons can adopt either approach with confidence depending on their preference if they are familiar with that approach.
