Doctors at the University of California, San Diego, have performed a weight-loss surgery where 80% of the patient’s stomach was removed through the mouth.
The surgeons said this may be the first time that a sleeve gastrectomy has been performed in the US.
Reduing the size of a patient’s stomach is intended to increase feelings of fullness and decrease food intake, resulting in weight loss.
Surgeons performed a laparoscopy as part of the procedure, making five incisions in the abdomen to insert instruments and cameras.
A small portion of tissue was also removed through the abdomen and staples were inserted close to the stomach.
Dr Santiago Horgan, director of the university’s Center for the Treatment of Obesity, said that removing the stomach through the mouth had minimised trauma to the abdomen.
“The absence of a large, open incision reduced the risk of hernia and greatly diminished pain for the patient,” Horgan said.
“We are getting closer to weight-loss surgery with no scars.”
