Cylindrical abdominoperineal resection for rectal cancer using the Hugo RAS system: The first ever case report for...

In May 2023, the Hugo RAS system obtained pharmaceutical approval for use in gastroenterological surgery in Japan. It is expected to be particularly effective in rectal cancer surgery, which require the manipulation of the deep pelvic cavity and communication with surgeons operating from the intraperitoneal and anal approaches. A 68-year-old woman presented to our hospital with bloody stools and was diagnosed with cStage I (cT2N0M0) rectal cancer and underwent abdominoperineal resection employing the Hugo RAS system. Two arm carts were placed on the left and right lateral sides with an interleg space, and trocars were placed in a straight line between the right superior iliac spine and umbilicus. Herein, we report the first abdominoperineal resection for rectal cancer using the Hugo RAS system.
