Duodenal Switch

This procedure begins with a sleeve gastrectomy. The valve that releases food to the small intestine is left, along with the first part of the small intestine, called the duodenum. The surgeon then closes off the middle section of the intestine and attaches the last part directly to the duodenum.This is the duodenal switch.

Bariatric Surgery Process

Bariatric Surgery & Obesity Specialists | Weight-Loss Surgery Center clinics in Walnut Creek and Brentwood California

1. Consultation

During the initial consultation, you will visit with Dr. Chin / Dr. Moy to go over your medical history, surgery options and answer any questions. Based on your medical history, the surgeon will determine the tests and clearances needed to proceed with surgery. During the initial consultation, you will also meet with our Program Specialist who will help prepare you for surgery by scheduling all of your pre-operative tests and clearances (to examine the esophagus, stomach and part of the small intestine).

2. Pre-Op Testing

Pre-operative tests and clearances may include a sleep study, EKG, chest x-ray, lab work and consultation with an anesthesiologist. Each patient must have an evaluation by our clinical therapist and an EGD two weeks prior to surgery. In addition, each candidate is required to attend a mandatory patient education class.

3. Surgery

All surgeries are performed at BASS Surgery Center. The nurses will assist with your post-operative nutrition and exercise recommendations. The length of time you spend in the hospital will depend on which procedure you have: gastric bypass, adjustable gastric banding or sleeve gastrectomy. The intragastric balloon is an outpatient procedure.

Excellent 4.8 out of 5 star rating

Great Doctors!

Dr. Jason Moy performed by bariatric surgery last month.  I did enormous study on the surgery including watching 90 hours of video on YouTube.  Concerned about the surgery Dr. Jason Moy had an excellent bedside manner.  He is an excellent listener and very patient.  His staff is impeccable.  His confidence shown in me and the procedure remedied my nerves.  After surgery I was expecting some of the maladies I learned about after bariatric surgery.  To my surprise and because of an excellent surgery, I had minimal pain off pain meds next day, no sore throat or other irritable symptoms. I knew I was fortunate.  Fortunate to have an excellent doctor and surgeon.  If you plan to change you life and go in a better direction and get bariatric surgery I would expect you would want the best surgeon and doctor available.  I suggest you call Dr. Jason Moy.  I am sure there are other great doctors but if you are looking for a sure thing then it is Dr. Jason Moy.

Life Changing Surgery

I underwent Gastric sleeve surgery with Dr. Chin not long ago. I had a wonderful experience. The process for this Bariatric weight-loss surgery was made very smooth by Dr. Chin's great staff and the preparation and advice from Dr. Chin. I would highly recommend Dr. Chin to anybody thinking about having a life changing weight-loss surgery, he's one of the best Bariatric Doctors/Surgeons in the East Bay.
