Purpose:
To evaluate the surgical feasibility of retroperitoneal laparoscopic adrenalectomy for tumors exceeding 5 cm.
Methods:
A retrospective review was carried out on all adrenalectomies performed between 2002 and 2011. All surgical procedures were performed or supervised by one of two experienced laparoscopic surgeons. A total of 133 patients who underwent retroperitoneal laparoscopic adrenalectomy were divided according to tumor size: group I (n = 57) had tumors <5 cm and group II (n = 76) had tumors ≥5 cm. The operative outcomes included surgical time, change in hemoglobin level, estimated blood loss, necessity for blood transfusion, time to ambulation, hospitalization duration, postoperative complications according to the Clavien-Dindo classification, and the rate of conversion to open surgery.
Results:
The estimated blood loss (271.75 ± 232.98 mL vs. 367.24 ± 275.11 mL; p = 0.037), time to ambulation (1.60 ± 0.49 days vs. 1.89 ± 0.31 days; p = 0.001), and postoperative hospitalization (7.88 ± 3.08 days vs. 9.264 ± 3.10 days; p = 0.012) were significantly higher in group II. The operation time and hemoglobin level change were not statistically different between groups. Blood transfusions were performed in 3 patients from group I and 6 patients from group II (5.3 vs. 7.9 %; p = 0.449). No patients experienced conversion to open surgery.
Conclusions:
Retroperitoneal laparoscopic adrenalectomy can be used in patients with tumors larger than 5 cm.
