Ask the Expert: Biliopancreatic Diversion With Duodenal Switch

28 May, 2019

Candice Chipman, MD
Candice Chipman, MD, is one of the first bariatric weight loss surgeons on Long Island who performs biliopancreatic diversion with duodenal switch (BPD-DS). Here, Dr. Chipman explains the BPD-DS procedure, which she performs utilizing St. Charles Hospital’s new, fourth generation da Vinci robot, the da Vinci Xi.

What is BPD-DS?
Dr. Chipman: BPD-DS is a bariatric weight loss procedure which combines a sleeve gastrectomy with a distal bypass. In a sleeve gastrectomy, the surgeon removes a portion of the stomach. In a distal bypass, the surgeon divides the small intestine and reattaches a segment of it to the newly sleeved stomach. The BPD-DS procedure can be performed as a single surgery or as two separate surgeries. That indication depends on the patient’s health status or whether they have had a previous bariatric surgery.

What are the advantages BPD-DS?
Dr. Chipman: Patients who have a BPD-DS report feeling full and experience reduced hunger. Their bodies also absorb less calories and fat. BPD-DS can help patients lose approximately 98 percent of their excess body fat while also resolving comorbidities, such as diabetes, hypertension, sleep apnea and high LDL cholesterol. Studies have also demonstrated that those who have undergone BDP-DS regain less than two percent of excess weight over a long period of time.

Who is an appropriate candidate for BPD-DS?
Dr. Chipman: Those who have a BMI of 50+ or those with a BMI in the high 40’s in conjunction with comorbidities most particularly diabetes. BPD-DS is an ideal revisionary surgery because it incorporates components of both a sleeve gastrectomy and a bypass. However, while bariatric weight loss centers have historically utilized BPD-DS as a second weight loss surgery for those who require a second, BPD-DS is increasingly chosen for those undergoing their first weight loss surgery.

What makes a BPD-DS successful?
Dr. Chipman: What makes BPD-DS successful is what makes all bariatric surgery procedures successful. Bariatric surgeries do not fail or succeed on their own. Our patients’ success hinges on the support of clinicians from several specialty areas. Together, with the assistance of our physician assistant, nutritionist and psychologist, we can ensure patients are prepared for surgery and are equipped with the information and strategies they need to increase, and then maintain, their weight loss after the procedure.
