Abstract

PURPOSE
To compare surgical outcomes between the lateral and the posterior approach for retroperitoneal laparoscopic adrenalectomy (RLA).
MATERIALS AND METHODS
We retrospectively reviewed the records of 130 patients who underwent RLA for adrenal tumors by a single surgeon between January 2015 and December 2018. Patient characteristics and perioperative outcomes were analyzed and compared between two surgical groups: lateral approach (n=56) and posterior approach (n=74).
RESULTS
There were no significant differences in perioperative outcomes between the two groups except for operative time (lateral approach, 105.4±41.21 minutes vs. posterior approach, 71.5±31.51 minutes; p=0.001). In the lateral approach group, two patients (3.6%) underwent open conversion, but there were no major complications in either group (Clavien-Dindo classification ≥3). Male sex was associated with an operative time of ≥90 minutes in the univariate analysis (p=0.019), but this effect did not remain significant in the multivariate analysis. In the multivariate analysis, large tumor size (>5 cm; p=0.020) and preoperative diagnosis of malignancy (p=0.043) were significantly associated with an operative time of ≥90 minutes.
CONCLUSIONS
Both the lateral and posterior approaches for RLA were performed safely with similar operative outcomes and are therefore comparable options for the treatment of adrenal tumors. In addition, large tumor size and preoperative diagnosis of malignancy are associated with longer operative times.
