The U.S. Food and Drug Administration today approved a new obesity treatment device that uses a surgically-placed tube to drain a portion of the stomach contents after every meal.
The AspireAssist device should not be used on patients with eating disorders, and it is not intended to be used for short durations in those who are moderately overweight. It is intended to assist in weight loss in patients aged 22 and older who are obese, with a body mass index of 35 to 55, and who have failed to achieve and maintain weight loss through non-surgical weight-loss.
To place the device, surgeons insert a tube in the stomach with an endoscope via a small incision in the abdomen. A disk-shaped port valve that lies outside the body, flush against the skin of the abdomen, is connected to the tube and remains in place. Approximately 20 to 30 minutes after meal consumption, the patient attaches the device’s external connector and tubing to the port valve, opens the valve and drains the contents. Once opened, it takes approximately five to 10 minutes to drain food matter through the tube and into the toilet. The device removes approximately 30 percent of the calories consumed.
Side effects related to use of the AspireAssist include occasional indigestion, nausea, vomiting, constipation and diarrhea.
The endoscopic surgical placement of the gastric tube is associated with risks, including sore throat, pain, abdominal bloating, indigestion, bleeding, infection, nausea, vomiting, sedation-related breathing problems, inflammation of the lining of the abdomen, sores on the inside of the stomach, pneumonia, unintended puncture of the stomach or intestinal wall and death.
contraindicated in those with certain conditions, including uncontrolled hypertension, diagnosed bulimia, diagnosed binge eating disorder, night eating syndrome, certain types of previous abdominal surgery, pregnancy or lactation, inflammatory bowel disease or stomach ulcers.
