Combined Restrictive & Malabsorptive Procedure

Gastric Bypass Roux-en-Y

In recent years, better clinical understanding of procedures combining restrictive and malabsorptive approaches has increased the choices of effective weight loss surgery for thousands of patients. By adding malabsorption, food is delayed in mixing with bile and pancreatic juices that aid in the absorption of nutrients. The result is an early sense of fullness, combined with a sense of satisfaction that reduces the desire to eat.

RNY is both a restrictive and malabsorptive procedure.  The surgeon divides the stomach in two parts; the large portion of the stomach is closed off with staples to create a smaller pouch.  The smaller stomach, your new pouch, restricts the amount of food you can eat at one time.  The small intestine is cut below the duodenum and reattached to the new stomach pouch, leaving a shortened path for food to travel through so less food is absorbed. 
Surgery risks include: staple line bleed, fistula, intestinal irritation, blockage, and ulcers.

Laparoscopic adjustable gastric banding

An adjustable gastric band is placed around the top part of the stomach dividing it into two parts: a small upper pouch and a lower stomach.  The size of the band is adjusted using a port placed under your skin.  Adjusting the band changes how much you can eat and how quickly food leaves the new pouch so patients feel full sooner and longer than usual. 
Surgery risks include: gastric perforation, port leakage or twisting, lack of satiety, reflux, nausea and vomiting, infection, outlet obstruction, pouch dilation and band slippage.

Gastric Sleeve Procedure 

The sleeve limits food intake by reducing the size of the stomach.  A stapling device is used to divide the stomach vertically, leaving behind a thin vertical sleeve of stomach.  The excised portion of the stomach is removed.
Surgery risks include:  staple line bleed, gastric leakage, nausea and vomiting.

All surgeries come with the potential risk of pulmonary embolism, deep vein thrombosis (blood clot in legs or lungs), infection, breathing troubles such as pneumonia and anesthesia  problems.
