Anthony Maffei, MD, takes pride in helping patients to lose weight and resolve obesity-related diseases such as diabetes and sleep apnea.


Are You a Candidate for Bariatric Surgery?

Candidates for bariatric surgery include individuals who have a body mass index (BMI) of 35 or higher and have obesity-related conditions, such as diabetes, high blood pressure or sleep apnea. Individuals who have a BMI over 40 are also candidates for weight-loss surgery.

Greenwich Hospital offers several types of bariatric surgery, each using minimally invasive techniques, resulting in less scarring and quicker recovery.
During a sleeve gastrectomy, surgeons remove roughly 85 percent of the stomach, creating a sleeve-shaped organ about the size of a small banana. “In addition to inhibiting caloric intake, removing part of the stomach in the sleeve gastrectomy reduces food cravings because it lowers levels of ghrelin, the so-called ‘hunger hormone,’” said Anthony Maffei, MD.

With gastric bypass surgery, surgeons first create a small stomach pouch about the size of an egg and then construct a “bypass” that allows food to skip parts of the small intestine, so the body absorbs fewer calories.

The gastric banding procedure places an adjustable band around the top part of the stomach to create a small pouch, making the individual feel full after eating a small amount of food.

During duodenal switch surgery, a larger portion of the stomach is left intact and more of the small intestine is rerouted, with greater reduction of caloric absorption.

Greenwich Hospital surgeons also do revision surgery of previous bariatric surgeries, including the conversion of gastric banding to gastric bypass surgery or a sleeve gastrectomy.

“We look at each individual’s underlying health conditions to determine the best procedure to help him or her overcome obesity,” said Cheryl Williams, RD, the program coordinator. “Our goal is not just weight loss, but improving quality of life.”
