Robotic Abdominal-Perineal Resection for Rectal Cancer Using da Vinci Single-Port System: Initial Clinical Experience in Japan.

The da Vinci Single-Port (dV-SP) is an innovative robot that integrates the advantages of articulated robotic instruments and a single access approach. A 58-year-old man who presented to our hospital with abdominal pain was diagnosed with cStageIIc (cT4bN0M0) rectal cancer and underwent abdominal-perineal resection using dV-SP. Its characteristic properties (cobra position of the camera, the wrists and elbows, and the relocating) allowed surgeons to overcome the challenges associated with single-port laparoscopic surgery, namely no clear triangulation and countertraction in the surgical fields, collision between straight instruments, and in-line viewing, and provide better cosmetic outcomes than those obtained by a multiport robotic surgery. We report the first surgery performed using dV-SP for rectal cancer in Japan.
