Modular approach for single docking robotic colorectal surgery
We have read the article by Priatno and Kim with great interest (1). The article and attached video describe the single docking technique for rectal resection using the da Vinci® Si system. Robotic rectal surgery has shown steady increase during recent times. With challenging ergonomics of heavy mechanical arm of the robotic Si system, arm collision was often quoted as the main reason for limited adoption. With this in mind, surgeons have tried various other techniques such as hybrid, laparoscopic assisted or double docking as possible solution to this problem (2-4).
