Laparoscopic Banded Roux-en Y Gastric Bypass Surgery in Mumbai

Laparoscopic Banded Roux-en Y Gastric Bypass Surgery

Laparoscopic Roux-en Y gastric bypass is one of the oldest and time tested bariatric procedures in the world. Commonly acknowledged as a gold standard weight loss procedure, this surgery is being performed for over 50 years all across the world and for almost 20 years in Mumbai.

Laparoscopic banded Roux-en y gastric bypass surgery is a modification of the standard gastric bypass where a silicon band is placed on the stomach pouch for better maintenance of weight in the future.

As per the IFSO-APC guidelines, if your BMI is more than 37.5 Kg/m² (BMI- weight in kg/height in m²), you can undergo a laparoscopic Roux-en Y gastric bypass in the absence of any associated illnesses. You can also undergo this procedure if your BMI is ≥ 32.5 Kg/m² and you have 2 or more obesity associated diseases like type 2 diabetes, high blood pressure, high cholesterol etc. As per the new DSS guidelines formed by a group of international diabetes federations in London, laparoscopic Roux-en Y gastric bypass may also be considered as a treatment option for control of diabetes in patients with class I obesity (BMI- 27.5-32.5 Kg/m²) if their diabetes is poorly controlled.

Laparoscopic banded Roux-en Y gastric bypass surgery

Laparoscopic banded Roux-en Y gastric bypass surgery is a surgical procedure in which a small pouch of the stomach is created using staplers and the small intestine is rearranged and joined to this stomach pouch. Major part of the stomach, duodenum- which is the first part of small intestine and the first part of jejunum is bypassed in this surgery. In laparoscopic banded Roux-en Y gastric bypass surgery, an inflexible silicon ring is placed on the stomach pouch. This ring helps in prevention of enlargement of the stomach pouch and the joint where the stomach pouch is attached to the intestine.

Mechanism of action of laparoscopic banded Roux-en Y gastric bypass surgery

Banded Roux-en Y gastric bypass surgery is one of the best bariatric procedures and leads to weight loss by a combination of multiple mechanisms. First of all, as the stomach pouch is very small, you will not be able to eat too much and your intake will be restricted. Secondly, you will feel full even after eating small quantities and will feel satiated much earlier. The band on the stomach pouch prevents the pouch from dilating in future and helps in the long term maintenance of weight loss. Thirdly, “ghrelin” the hunger inducing hormone which is produced from the fundus of the stomach, does not come in contact with the food and hence the sensation of hunger is curbed to a large extent. Fourthly, as the stomach and first part of intestine are bypassed, banded Roux-en Y gastric bypass surgery also leads to some degree of mal-absorption. In addition to this there are GI hormones that play a big role in weight loss as well as control of diabetes. There are also other factors like bile acids, gut microbiota and certain unknown factors that augment the effect of a banded Roux-en Y gastric bypass surgery.

Expected results after surgery

Bariatric/metabolic surgery is the only proven method for sustained weight loss in people suffering from clinically severe obesity. Most bariatric procedures will lead to an excess weight loss to the tune of 65 to 75% over a period of 18 to 24 months. This weight loss journey is a partnership between the doctor and the patient and the results depend on the level of commitment from either party. All bariatric procedures lead to a significant improvement in type 2 diabetes, high blood pressure, high cholesterol, gout, obstructive sleep apnoea, venous thrombo-embolism, PCOD, infertility and many other diseases related to obesity. Weight loss leads to a significant decrease in the risk for heart disease also. Overall, bariatric/metabolic surgery leads to a marked improvement in health, quality of life and confidence of the patient.

The doctor will guide you about the cost after assessing and evaluating all the above details.

Laparoscopic banded Roux-en Y gastric bypass surgery FAQ’s (Frequently Asked Questions)

1. What is banded laparoscopic Roux-en Y gastric bypass? Is it advisable?

In a banded laparoscopic Roux-en Y gastric bypass, a non-adjustable silicon ring is placed around the stomach pouch. Dr. Aparna Govil Bhasker recommends this over a normal non-banded laparoscopic Roux-en Y gastric bypass as this helps in long term weight maintenance. In a non-banded laparoscopic Roux-en Y gastric bypass, there are chances of weight regain in future whereas with a banded laparoscopic Roux-en Y gastric bypass, chances of weight regain are reduced. Its biggest advantage is that it helps to maintain restriction in the long term. Though it is safe in approximately 98% of patients, 2 to 3% patients may experience erosion or slippage of the ring. If the ring were to erode into the stomach pouch, most of the times it can be removed non-surgically by endoscopy.

2. How much weight loss is expected after a laparoscopic Roux-en Y gastric bypass?

Weight loss is a gradual process after a laparoscopic Roux-en Y gastric bypass. You will lose weight quite fast in the first 3 to 4 months after which, weight loss slows down. You will continue to lose weight for about 12 to 18 months after your surgery and can expect to lose about 65 – 75% of your excess weight with help of a laparoscopic Roux-en Y gastric bypass.

It is important to note that bariatric/metabolic surgery is a tool that pushes you into a lifestyle change. While bariatric/metabolic surgery helps to lose massive amount of weight, it is also important to exercise every day and follow a healthy diet. Our experience shows that patients who embrace the lifestyle change along-with surgery, tend to do much better in terms of weight loss and weight maintenance.

3. Does diabetes improve after a laparoscopic banded Roux-en y gastric bypass surgery?

Banded Roux-en y gastric bypass surgery is known to lead to improvement in type 2 diabetes. It has been observed that a lot of patients do not need to go back on their anti-diabetic medications after the surgery. For those who need to continue medications, the dose is reduced considerably and a lot of times patients who have been on insulin may not require it post-operatively. The outcomes of diabetes remission depend on a lot of factors like the duration of diabetes, type of diabetes (type 1/type 2), age of the patient, c-peptide levels, use of insulin etc. It also leads to improvement in other associated diseases like high blood pressure, high cholesterol, obstructive sleep apnoea, gout, joint diseases, PCOD, infertilty etc. The overall risk for heart disease goes down considerably due to significant weight loss and overall improvement in associated co-morbidities.

4. I am diabetic but not overweight or obese. Am I eligible to undergo a laparoscopic banded Roux-en Y gastric bypass surgery?

Banded Roux-en Y gastric bypass surgery has been shown to lead to remission or improvement in obese diabetics. Most often their blood sugars come under control within a few months of surgery and a lot of times patients do not need to take medications.

If you are a diabetic but you are not overweight or obese, the chances are that this surgery may not help you for improvement of diabetes. The latest DSS guidelines recommend metabolic surgery for patients with a BMI greater than 27.5 kg/m² if their diabetes is uncontrolled despite best medical management. Presently, there is no evidence to recommend this surgery to a diabetic patient with a BMI less than 27.5 kg/m².
