Initial Experience of Robot-Assisted Adrenalectomy in Japan: What is the Optimal Selection of Robotic Forceps for Adrenalectomy?

Abstract

Minimally invasive adrenalectomy is the preferred technique for managing adrenal tumors. Laparoscopic adrenalectomy is widely performed and covered by insurance in Japan, but robot-assisted adrenalectomy is not. To investigate the best forceps combinations for performing robot-assisted adrenalectomy safely, we performed robot-assisted adrenalectomy for two left and two right adrenal adenomas using different robotic forceps combinations (bipolar forceps, monopolar curved scissors, Vessel Sealer Extend, and SynchroSeal) for each case. Although we evaluated a small number of RAs, lower blood loss was observed in patients where the vessel sealing devices were used. The extent of dissection is small for adrenalectomy, and robotic bipolar vessel sealing tools may not be necessary, especially for the small adrenal tumors. However, considering the risk benefits, the combination of forceps with Vessel Sealer Extend (by the left arm) and monopolar curved scissors (by the right arm) will become one of the best forceps combinations for performing robot-assisted adrenalectomy safely.
