Gastric Reduction – Duodenal Switch (LGRDS-DS)
- No part of the bowel (intestine) is removed in surgery.
- Although the stomach is restricted, it will stretch in time. Approximately 12 months following surgery patients are able to eat 60% the amount of food eaten prior to surgery.
- The length of the surgical procedure is 2.5 to 5 hours.
- Average hospital length of stay is 3 days.
- Weight loss will level out in approximately 12 to 24 months.
Patients are losing 85% to 95% of the excess body weight within one to two years following surgery. A patient’s weight and BMI prior to surgery does have an effect on the weight loss as well as the compliance of a patient to follow post operative instructions.
Studies have shown that the long term success in this surgical procedure for morbid obesity is approximately 85% of the excess body weight loss. This weight loss has proven to be the most successful for the treatment and alleviation of hypertension, Type II diabetes, sleep apnea, hypercholesterolemia, pain associated with arthritic changes in joints, asthma and urinary stress incontinence as well as improving psycho-social activities.
