Minimally Invasive Surgery
Also written as: MIS — Minimally Invasive Surgery
Surgical techniques using small incisions and specialized instruments to minimize tissue trauma while maintaining oncologic principles.
Full Definition
Minimally invasive surgery (MIS) in oncology encompasses laparoscopic and robotic techniques that achieve equivalent oncologic outcomes to open surgery while reducing patient morbidity. Key principles include maintaining adequate margins, proper specimen handling, avoiding tumor spillage, and adhering to established oncologic planes of dissection. Common applications include colorectal resections, gastric surgery, and select hepatic resections. Benefits typically include reduced blood loss, shorter hospital stays, and faster recovery, though patient selection and surgeon experience are critical factors in successful outcomes.
Usage
Usage note: Encompasses both laparoscopic and robotic approaches. Emphasize oncologic equivalency when documenting outcomes.
