This video demonstrates the standardized procedure of robot-assisted right hemicolectomy via the medial approach, aiming to promote a safe and efficient minimally invasive technique. The procedure employs a standard four-arm robotic system, with the patient in a head-up, left-tilted position. Using a ventral-caudal approach as the first cutting, dissection is initiated beneath the ileocolic vessels to access the posterior ascending colon space. The Toldt's interface is precisely exposed with the following main trunk of the superior mesenteric vessels. The ileocolic, right colic, and right branch of the middle colic arteries are sequentially ligated and divided at their origins, and regional lymph nodes are completely dissected. The whole right sight colon is then mobilized in a counterclockwise direction. This approach does not require frequent position changes, adheres entirely to the concept of membrane anatomy, and effectively leverages the robotic system's advantages of stability and dexterity, serving as a reference for robot-assisted minimally invasive radical surgery for right colon cancer.
