Robotic approach for gastric cancer treatment

Surgeons at UC San Diego Health System have performed the region’s first robotic gastrectomy, a potentially lifesaving procedure to remove a section of the stomach after a diagnosis of gastric cancer. Aided by a da Vinci robot, surgeons remove the diseased tissue, perform a delicate reconstruction and remove local lymph nodes for further testing.

“To treat the gastric cancer, we remove part or all of the stomach with five small incisions,” said Kaitlyn Kelly, MD, surgical oncologist at UC San Diego Health System. “The goal of the robotic approach is to remove the cancer and carefully extract nearby lymph nodes in a highly precise way to achieve a more accurate cancer staging.”

Kelly’s patient, a woman of Korean descent, was diagnosed with stomach cancer after reporting upper abdominal pain to her physician. Korean men and women are five to seven times more likely than Caucasians to develop gastric cancer, which is the fourth most common cancer worldwide.

Also known as an adenocarcinoma, stomach cancer arises from the mucus-producing cells of the stomach lining. Early detection and accurate staging are essential to the patient’s long-term survival. Staging describes the extent or severity of a person’s cancer. Patients with a diagnosis of gastric cancer typically complain of upper stomach pain, persistent and severe heartburn or stomach fullness shortly after eating.

“What is special about the robotic approach is the ability to carefully remove the lymph nodes around large blood vessels without causing damage to the nodes or vessels. This robotic approach can potentially offer a better specimen for pathologists to evaluate,” said Santiago Horgan, MD, chief of minimally invasive surgery at UC San Diego Health System and director of the Center for the Future of Surgery at UC San Diego School of Medicine.
