Weight Loss Surgery Options

We understand how difficult weight loss can be. Even with the best of efforts, managing your weight can involve frustrating ups and downs, and can even feel hopeless at times. Weight loss surgery (also known as bariatric surgery) offers an opportunity to reset your weight to a point where it's more manageable. Surgery can also greatly improve your health and quality of life.

We also recognize that the idea of weight loss surgery can be intimidating for many. However, most people who have weight loss surgery keep the weight off long-term and, often, their only regret is that they didn't do it sooner.

Minimally Invasive Approaches

All of our weight loss surgeries are done in a laparoscopic (minimally invasive) way using state-of-the-art technology. This means your surgeon uses just a few dime-sized cuts. Because it is a minimally invasive surgery, there is a shorter recovery time compared to traditional open surgery. Patients are discharged from the hospital after 1 to 2 days. Following surgery, we'll provide ongoing nutritional and dietary guidance to help you keep the weight off and identify strategies to ensure you maintain your new healthier lifestyle.

We offer the following weight loss surgical procedures:

  • Laparoscopic sleeve gastrectomy: In this procedure, surgeons remove the outer section (or crescent) of the stomach. The smaller stomach that remains looks like a narrow sleeve. This surgery reduces how much food the stomach can hold by 75 percent. This treatment also affects the hormones that control appetite, so you feel less hungry.
  • Laparoscopic gastric bypass surgery: In this procedure, surgeons reduce the size of the stomach by about 90 percent. The smaller stomach that remains looks like a pouch that’s about the size of an egg. The new stomach pouch is then connected to a lower point in the small intestine, so that food bypasses (goes around) the upper part of the small intestine. This surgery works by limiting how much food your stomach can hold and changing how food is absorbed.
  • Laparoscopic/Robotic Duodenal Switch (DS) Surgery: In this procedure, surgeons perform a sleeve gastrectomy (remove the outer portion of the stomach) so that the new stomach looks like a narrow sleeve. The upper small intestine gets divided and the lower intestine is divided much further down than the Gastric Bypass, so it is the most malabsorptive procedure. This part gets connected to the stomach. The remaining intestine is connected back to itself to allow enzymes and bile to mix with food, to support digestion. In the DS, one more connection is made than the SADI-S.
  • Laparoscopic/Robotic Single Anastomosis Duodenoileostomy with Sleeve Gastrectomy (SADI-S): In this procedure, surgeons perform sleeve gastrectomy (remove the outer portion (also called crescent) of the stomach) so that the new stomach looks like a narrow sleeve. In addition, part of the upper small intestine gets divided and connected to a loop of the lower, small intestine.
  • Revision surgery: Patients who’ve had a previous weight loss surgery can receive adjustments to that surgery in the form of reversals, modifications or conversions from one type of surgery to another. Each revision case is unique and our expert revisional team—one of the largest and most experienced in the region—can work with you to evaluate your options.
