Abstract

One Korean company recently successfully produced a robotic surgical system prototype called Revo-i (MSR-5000). We, therefore, conducted a preclinical study for robotic cholecystectomy using Revo-i, and this is a report of the first case of robotic cholecystectomy performed using the Revo-i system in a preclinical porcine model. Revo-i consists of a surgeon console (MSRC-5000), operation cart (MSRO-5000) and vision cart (MSRV-5000), and a 40 kg-healthy female porcine was prepared for robotic cholecystectomy with general anesthesia. The primary end point was the safe completion of these procedures using Revo-i: The total operation time was 88 minutes. The dissection time was defined as the time from the initial dissection of the Calot area to the time to complete gallbladder detachment from the liver bed: The dissection time required 14 minutes. The surgical console time was 45 minutes. There was no gallbladder perforation or significant bleeding noted during the procedure. The porcine survived for two weeks postoperatively without any complications. Like the da Vinci surgical system, the Revo-i provides a three-dimensional operative view and allows for angulated instrument motion (forceps, needle-holders, clip-appliers, scissors, bipolar energy, and hook monopolar energy), facilitating an effective laparoscopic procedure. Our experience suggests that robotic cholecystectomy can be safely completed in a porcine model using Revo-i.
