Advantages of the umbilical minilaparotomy-first approach in robotic rectal cancer surgery.

Background: Since 2018, we have performed robotic rectal cancer surgery at our institution via the umbilical mini-laparotomy-first approach. In the present technical note, we introduce the advantages of this approach.

Methods: In this approach, a 3-cm mini-laparotomy and the wound protector attachment are performed prior to port placement for the da Vinci Xi system.
