Gastric Sleeve

The Gastric Sleeve can be performed for patients with a Body Mass Index (BMI) greater than 35. Calculate your BMI. This procedure is performed laparoscopically in about 45 minutes. Thin instruments, and a tiny camera are used to do the entire procedure allowing us to complete the whole thing using a few small 5mm to 10mm skin incisions. During the procedure, approximately 75% of the stomach is removed, leaving a smaller stomach in the shape of a banana. This is a common sense surgery: A small stomach means you feel full after eating just a small amount of food, and the less you eat, the more you lose. Ofcourse, eating healthy food is always recommended, since eating calorie dense junk foods will minimize the results. Since there is no cutting or re-routing of intestines (which are important in absorbing nutrients), there is very little loss of vitamins and nutrients that our body needs.

Stomach Before and After Gastric Sleeve

Technical Aspects

The stomach is measured using a tube called a bougie, which is temporarily placed inside the stomach as a guide to sizing the gastric sleeve. The smaller the bougie diameter, the smaller the gastric sleeve can be made. The stomach created is just enough to help you lose 60-70% of your extra weight while allowing you to eat a normal healthy diet.

Staples & Sutures

The standard way to perform a gastric sleeve is by using cutting staple devices that cut and seal the stomach, simultaneously. This allows us to create and seal the banana shaped stomach mentioned earlier. There are 2 leading companies that make these stapler devices. Both have been around for years, both are well-respected brands, and there is no consensus among surgeons on which is better. Bariatric surgery is serious work, so it becomes obvious for us to use the best products available, and as technology and knowledge advances, we make sure to keep up with the advancements. The staples themselves are less than 2 mm in length, which is tiny by any measure. Although hundreds of such staples are used during the surgery, they are harmless; they don’t set off alarms, and don’t lead to unnecessary fondling by airport security. There is no such thing as doing a sleeve without staples. I say this because once in a while someone will ask me not to use staples, but only sutures instead. Sutures can be used additionally, on top of the staple line for added security.

Buttressing Materials

Buttressing materials are thin strips of reinforcement materials that sandwich the staple line on both sides of the stomach, for added strength. Two such materials are available Peristrips®, and Seamguard®. These have shown to decrease oozing from the staple line and may be used during the procedure.

Leak Tests

A leak test is used in the operating room right after the new stomach pouch is created, to make sure the staple line is completely sealed, and there is no micro-hole in the stomach that is not visible to the naked eye.

  • I have never felt better physically, emotionally and spiritually in my LIFE! I have made a commitment to myself to live a healthier lifestyle and Dr. Mehta has helped in this decision and choice. Down 80 lbs with the lap band.*

  • I chose Dr. Mehta because he came highly recommended by my gastrointestinal doctor. Before surgery my maximum weight was 338 lbs. My current weight, one year post-op is 205 lbs. I had no trouble getting an appointment with Dr. Mehta’s office and I found the staff to be kind and very informative and supportive. Dr. Mehta answered all of my questions thoroughly and was very attentive when I developed post op complications. I have not taken advantage of the support staff in place, but I know they’re available should I need them. I would highly recommend Dr. Mehta and the Mehta Bariatric Center to anyone considering bariatric surgery. It has made a tremendous impact on my life.*

  • Dr. Mehta and his staff (especially Lulu) are great!! Dr. Mehta has a great bedside manner and takes the time to talk to you and answer any and all questions that you may have. My situation was different than most. I had an old gastric banding placed in back in 1985. My surgery was performed by a surgeon who no longer practices. The banding had gone bad and eroded through my stomach causing a lot of pain. I had gone to many doctors and finally met Dr. Mehta who decided to help me by performing corrective surgery to remove the band and perform the new gastric bypass. I was back up to 225 lbs and I am now down to 140 lbs. My husband met with Dr. Mehta while he was in the hospital and liked his manners and asked me to call him. I had no problem getting an appointment and he explained everything I needed to know. I had the surgery and I am now feeling great and no longer in pain. I love Dr. Mehta and his staff. I felt I made a great choice and I am glad he took my case on and helped me out.*

  • I heard about Dr. Mehta through my mother. I felt very comfortable around him. At our first meeting, Dr. Mehta explained the procedure and all risks with me. The staff that Dr. Mehta has is very friendly and helpful with all your questions. I felt like Lulu was a personal friend of mine. Before my surgery, I weighed 237 lbs now I am weighing 145 lbs. I feel great!! I have not been able to utilize the Mehta Bariatric Center’s after care program because of where I live, in Delaware. If I lived closer, I wouldn’t hesitate to utilize it. I highly recommend Dr. Mehta and the Mehta Bariatric Center.*
