Technique: Minimally invasive congenital biliary dilatation (CBD) surgery is technically demanding. However, few studies have reported surgical approaches of robotic surgery for CBD. This report presents robotic CBD surgery using a scope-switch technique. Our robotic surgery technique for CBD consisted of four steps: step 1, Kocher's maneuver; step 2, dissection of the hepatoduodenal ligament using the scope switch technique; step 3, preparation for the Roux-en-Y loop; and step 4, hepaticojejunostomy. Results: The scope switch technique can provide different surgical approaches for dissecting the bile duct, including anterior approach by the standard position and right approach by the scope switch position. When approaching the ventral and left side of the bile duct, anterior approach with the standard position is suitable. In contrast, the lateral view by the scope switch position is preferable for approaching the bile duct laterally and dorsally. Using this technique, the dilated bile duct can be dissected circumferentially from four directions: anterior, medial, lateral, and posterior. Thereafter, complete resection of the choledochal cyst can be achieved. Conclusions: The scope switch technique in robotic surgery for CBD can be useful for dissecting around the bile duct with different surgical views, leading to the complete resection of the choledochal cyst.
