Robotic Assisted surgery has proven to show signi cant advantages in surgery, for patients and surgeons alike. Nontheless the elevated cost remains a barrier to its acceptance in the medical eld. Strategies to reduce cost should be implemented as a way to ensure cost-effectiveness in robotic-assisted procedures.The aim of this article was to compared the performance of the new generator E100 (Intuitive Surgical, Inc.) vs. VIO dV 2.0 (Erbe Elektromedizin GmbH) by analyzing the number of times the generators were activated, the average time per seal, total sealing time, and console time. Financial impact based on annual volume was determined. A total of 1,457 sleeves gastrectomies (Erbe:746, E100:711) were analyzed, the average activation per case was similar in both groups. The sealing time dropped by 42.3% and the average console time dropped by 8 minutes in cases with the E100. The nancial analysis
