New Surgical Technique – Stomach Intestinal Pylorus-Sparing Surgery, SIPS – Addresses Challenges of Established Weight Loss Surgeries

Mitchell Roslin, MD - Director of Bariatric Surgery at Northern Westchester Hospital

Northern Westchester Hospital announced today that the work of Bariatric Surgeon Mitchell Roslin was presented at Obesity Week, an international medical meeting sponsored by the American Society for Bariatric and Metabolic Surgery and The Obesity Society recently in Boston, MA. The latest modification of bariatric surgical technique called SIPS was the topic of a podium presentation based on the work of Dr. Mitchell Roslin, New York bariatric surgeon, and Dr. Daniel Cottam of Salt Lake City, one-year weight loss and complication rates were presented. Weight loss exceeded gastric bypass and sleeve gastrectomy with no suggestion of increased complication.

The technique is based on several research studies conducted by Dr. Mitchell Roslin, Director of Bariatric Surgery at the Surgical Weight Loss Program at Northern Westchester Hospital. Dr. Roslin has presented and spoken internationally about improved outcomes that are associated with preserving the pyloric valve, which is located at the bottom of the stomach and controls the emptying of solid food from the stomach. Stomach Intestinal Pylorus-Sparing Surgery or SIPS, combines a sleeve gastrectomy with a procedure that shortens the amount of intestine used to absorb food. The response was so overwhelmingly positive that an educational symposium at Obesity Week sponsored by Covidien Inc was oversubscribed.

The expectation of the SIPS weight loss procedure is that it can provide weight loss that is greater than sleeve or bypass, and minimize the risk of micronutrient and vitamin deficiency. Dr. Roslin explains, “all procedures that have this level of efficacy will require lifetime vitamin and mineral supplementation. This is not a procedure for all patients, but may be the best alternative for those who have the highest BMI, are very frightened about weight regain, and have severe metabolic syndrome.”

Bariatric surgery usually involves a reduction of the size of the stomach, either functionally or literally, with modification of the small intestine in many cases. Dr. Roslin describes the SIPS bariatric surgery as a modification of an established technique known as duodenal switch surgery: A portion of the stomach is removed and a section of the small intestine is divided. The section just underneath the division is then attached directly to the duodenum so food can pass through it, while the original section of intestine is reattached at a lower point along the intestine to allow digestive juices to enter the system. However, "This technique has traditionally posed certain challenges” says Dr. Roslin.

According to the New York bariatric surgeon, SIPS is simpler as no intestine is removed, and SIPS requires only a single attachment as opposed to the two attachments done in gastric bypass or classic duodenal switch procedures. The data thus far shows by preserving three meters of intestine, nutrition needs are met.

Patients who undergo the stomach intestinal pyloric-sparing surgery can achieve impressive levels of weight loss that only are rivaled by duodenal switch. An initial one-year study of recipients showed an average weight loss of 40 percent of total body weight.

Certain criteria must be met to qualify for any type of bariatric surgery.

In addition to his position at Northern Westchester Hospital, Dr. Roslin practices at Lennox Hill Hospital as chief of Obesity Surgery. He also serves as President of Manhattan Minimally Invasive and Bariatric Surgery PC. Dr. Roslin also enjoys an international reputation as a speaker and lecturer on bariatric surgery procedures and issues.
