Laparoscopic Versus Robotic Adrenalectomy in Pheochromocytoma Patients.

Background and Objectives: Pheochromocytoma is a challenging tumor type requiring resection with a clear margin and an intact capsule to prevent recurrences. Our aim was to compare perioperative outcomes of laparoscopic adrenalectomy (LA) versus robotic adrenalectomy (RA) for pheochromocytoma. Methods: In an institutional review board-approved retrospective study, clinical parameters of patients who underwent LA versus RA at a single center were compared using Mann-Whitney U, chi(2) and survival analyses. Continuous data are expressed as median (interquartile range). Results: There was a total of 157 patients (RA: n = 87, LA: n = 70) analyzed. Estimated blood loss (36.3 [35.0] vs. 99.9 [65.0] cc, p = 0.020) and hospital stay (1.3 [0.0] vs. 2.2 [1.0] days, p = 0.010) were lower in robotic versus laparoscopic group, respectively. Disease-free and overall survival was similar between groups. The rate of conversion to open for tumors cm was less in the robotic group (0% vs. 14%, respectively, p = 0.048). Conclusion: In this study, long-term outcomes of LA and RA were similar, although adrenalectomies performed robotically were associated with less blood loss, shorter hospital stay, and a lower chance of conversion to open in the case of large tumors.
