During this procedure, Dr. Lavin reduces the stomach into a smaller, tubular pouch and then attaches a section of the small intestine to the stomach. The excised portion of the stomach is removed. By creating a small stomach pouch, the stomach has smaller capacity and will hold less food. Additionally, the food will bypass most of the small intestine where calories are normally absorbed; thereby, decreasing the amount of calories absorbed.

A Patient’s Journey Throughout the Biliopancreatic Diversion with Duodenal Switch

Our Patient's first step

Our patient’s first step is to call our office and speak with a Patient Advocate. Our Patient Advocates are advocacy experts who help patients secure financing, insurance approval and explain our cash pay options.

Pre-Procedure clinic visit

During the initial clinic visit, our patients meet with one of our nurse practitioners to determine whether any pre-operative testing is needed prior to surgery. Pre-operative tests are sometimes necessary to make sure our patients are healthy enough to undergo a procedure.

Following the initial clinic visit, our patients will be assigned a case manager. Our case managers answer patient questions and discuss any concerns prior to surgery.

The Biliopancreatic Diversion with Duodenal Switch

Our patients meet with Dr. Lavin or one of our nurse practitioners in clinic approximately 7-10 days prior to their procedure (special arrangements are made for our traveling patients).

A Biliopancreatic Diversion with Duodenal Switch takes between 1-2 hours. Our patients remain in the recovery room for 1-2 hours and typically begin walking the hallways and drinking liquids around that same time. Patients are usually discharged the next morning.


Our patients follow-up with Dr. Lavin or one of our nurse practitioners periodically following the procedure to insure healthy weight loss goals are met.

What are the advantages?

  • Often results in significant long-term weight loss (on average 60 to 80 percent excess weight loss)
  • Does not restrict types of food that can be eaten and allows for larger meals
  • Can resolve or improve co-morbidities such as diabetes, high blood pressure, sleep apnea, and high cholesterol

What are the risks?

As with any surgery, there are risks associated with the procedure; however, the health benefits as well as quality of life improvements far outweigh any risk of complications. Dr. Lavin will personally discuss the risks with each patient prior to surgery.
