The use of a robot to assist with the most commonly performed weight-loss surgery appears to significantly lower a patient’s risk of developing a rare but serious complication, according to a study published in the most recent edition of the Journal of Robotic Surgery.

A report in the September Cell Metabolism, a publication of Cell Press, offers new evidence to explain why those who undergo gastric bypass surgery often show greater control of their diabetes symptoms within days.

Morbidly obese patients who undergo a particular type of gastric bypass surgery called Roux-en-Y gastric bypass (RYGB) are at an increased risk of developing kidney stones – small, pebble-like deposits that can result in severe pain and require an operation to remove them – earlier than previously thought.

Losing weight may help resolve erectile dysfunction in obese men, according to research presented today at the 103rd Annual Scientific Meeting of the American Urological Association (AUA).

Obese patients who suffer complications after gastric bypass surgery may face further health risks because their weight exceeds the limits of diagnostic imaging equipment, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Obese Medicaid patients who undergo Roux-en-Y gastric bypass surgery may be more likely to return to work than obese Medicaid patients who do not undergo the surgery, according to a report in the October issue of Archives of Surgery, a theme issue on bariatric surgery.

High-risk morbidly obese patients who lose 5 to 10 percent of their excess body weight before undergoing gastric bypass surgery appear to have shorter hospital stays and more rapid postoperative weight loss, according to a report in the October issue of Archives of Surgery, a theme issue on bariatric surgery.

Two studies by a group of researchers at Washington Hospital Center highlight potential postoperative nutritional deficiencies among patients who undergo gastric bypass surgery to treat obesity.

Severely obese patients who undergo gastric bypass surgery significantly reduce their risk of death from coronary heart disease, diabetes, and cancer, according to research published in the Aug. 23, 2007, issue of The New England Journal of Medicine.

Bariatric surgery patients had 64 percent fewer complications and a 26 percent shorter hospital stay if they went to a five-star rated hospital compared with a one-star rated hospital, according to a new study released today by HealthGrades, the healthcare ratings company.

A simple scoring system based on five medical factors accurately predicts which patients being considered for gastric bypass surgery would be at highest risk of dying.
