Gastric bypass (also known as “Roux-en-Y” or “the bypass”) is the most common weight loss surgical procedure performed worldwide. It has the longest proven track record and has more long term studies proving its efficacy and is therefore considered by many as the ‘gold standard’ of weight loss surgery. This operation has been the most effective in ensuring long-term weight loss. Patients can typically lose 70-80% of their excess weight within the first year. It is also a highly effective treatment for diabetes in obese individuals.
Laparoscopic gastric bypass allows this procedure to be performed with only a few small incisions in the abdomen, and the use of a camera and specialized instruments. The smaller incisions cause less pain following surgery, fewer complications during recuperation, and shorter recovery times than open procedures. Laparoscopic gastric bypass, as opposed to open procedures, has less of a chance of complications during and after surgery, also requiring shorter hospital stays and recovery periods. The surgeons at The Bariatric Center of Kansas City have performed the most laparoscopic gastric bypass surgeries in the Midwest.
Laparoscopic Roux-en-Y gastric bypass causes weight loss by significantly restricting the amount of food you can eat, allowing less absorption of calories, and suppressing hunger and promoting the feeling of fullness. In this operation, no organs are removed and no foreign implants are placed.
The stomach is divided into a small “pouch” which food will go into, and one large “remnant stomach” through which the food no longer passes. This “excluded” or “remnant stomach” remains in the body and still produces helpful digestive juices which meet up with the food downstream. The upper, smaller “pouch” or “new stomach”, which can hold only about one ounce of food, is connected directly to a portion of the small intestine bypassing the larger chamber created by the procedure. By having a smaller stomach patients will eat much smaller meals and consume less calories. By rerouting the intestine, the food spends less time in the digestive system and the body absorbs less fat and calories from the food. Most importantly, the rerouting of the food stream produces changes in gut hormones that promote satiety, suppress hunger, and reverse one of the primary mechanisms by which obesity induces type 2 diabetes. That is why current research proves that gastric bypass is the best treatment for type 2 diabetes in obese patients.
Laparoscopic Roux-en-Y gastric bypass surgery requires an overnight hospital stay. Significant changes to diet and lifestyle are needed to ensure patient safety and success. To lose weight after bariatric surgery you must continue following the diet and exercise guidelines given to you by the surgeon. After gastric bypass, you will need to take vitamin and mineral supplements to ensure adequate nutrition and optimal health. We require some follow up visits to monitor your progress and evaluate your health after surgery.
The Bariatric Center of Kansas City is the largest center for laparoscopic weight loss surgery in the Kansas City metropolitan area. We are listed by the Surgical Review Corporation as a Bariatric Center of Excellence.
Dr. Stanley Hoehn has served on university faculties and have received specialty training in the field of laparoscopic weight loss surgery from surgeons who developed laparoscopic techniques. In addition to the dedicated surgeons, we are also staffed with with physician assistants, nursing and supporting staff that have years of experience in providing compassionate, American Society for Metabolic and Bariatric Surgery patient-centered care.
