Bariatric surgeries available at Lodi Memorial Hospital
Roux-en-Y gastric bypass
Gastric bypass is the most common type of weight loss surgery and there are extensive long term studies showing the effectiveness of this surgery. During this procedure, the bariatric surgeon divides the stomach and creates a pouch or new smaller stomach, and leaves a larger portion of the stomach through which food no longer passes. The small bowel is then divided and attached up to the new pouch, so that food traveling downward goes directly from the “pouch” and into the small intestine, bypassing the larger stomach and the beginning section of the intestine – hence the name gastric bypass. The remnant stomach continues to produce gastric juices which meet the food where the small bowel is attached below. In the beginning, this reduces the amount of food a patient can eat (“restriction”), but the in the long term gastric bypass works by changing the metabolism of the patient. Through this surgery, the way the brain and the gut talk to each other is changed thus patients don’t feel hungry.
Gastric bypass is strongest metabolic procedure of the three common bariatric surgeries, meaning that it has the highest rate of remission for diabetes, hypertension and hyperlipidemia at 80-90 percent. Long term weight loss results are great- most patients retain 60-70 percent of their extra body weight at 10 years after surgery.
Vertical sleeve gastrectomy
The newest of all weight loss surgeries is the vertical sleeve gastrectomy. This is a simple surgery where approximately 75 percent of the stomach is permanently removed, thus giving the stomach the shape of a tubular sleeve as opposed to a large pouch. Although this is a newer procedure, the current studies show that the remission rates of diabetes, hypertension and hyperlipidemia are in the 70-90 percent range, making this procedure slightly less strong than the gastric bypass. This is often performed on those with high risk patients who may return for a second surgery at a later time. Most patient lose approximately 60 percent of their extra body weight by year after surgery.
Adjustable gastric band
The adjustable gastric band (also known as the Lap Band®) is a procedure in which the surgeon places an adjustable plastic band at the top of the patient’s stomach creating a small pouch on top with the rest of the stomach below the band. The tightness of the band may be adjusted by the surgeon. The band works by slowing down the food which helps patients eat less and eat more slowly. However, there are virtually no metabolic benefits from this surgery which means that success of the patient depends largely on the patient’s choices. Patients who routinely snack throughout the day, take in liquid calories, or have a sweet tooth are not ideal candidates for the adjustable gastric band. The average patient will lose 30 percent of his/her extra body weight in the long term.
