Gundersen Health System's bariatric surgery program is among the best in the nation. Research is part of the reason we have built such a successful program. We conduct research studies to remain at the cutting edge of bariatric surgery.
Three significant bariatric studies conducted at Gundersen are:
Excellent Laparoscopic Gastric Bypass Outcomes can be Achieved at a Community-Based Training Hospital with Moderate Case Volume
This study compiled the results of 700 patients who underwent laparoscopic gastric bypass surgery at Gundersen. Results were compared to published outcomes. The data in nearly every category was equal to or superior to the results of other bariatric programs showing that excellent outcomes can be achieved in a community hospital program with a moderate case volume. Published in Annals of Surgery, 252(1), 43-49. (2010).
The Natural History and Metabolic Consequences of Morbid Obesity for Patients Denied Coverage for Bariatric Surgery
This study compared the medical records of patients who had bariatric surgery to others who were medically eligible for the surgery but were denied by their insurance providers. After three years, the average body mass index (BMI) of the surgical group dropped to 30.5. The BMIs for the other group remained unchanged and several developed other illnesses including hypertension, obstructive sleep apnea and gastroesophageal reflux disease (GERD). The research showed the surgery can prevent new diseases and offers health insurers a new reason to consider covering bariatric surgery. Published in Surgery for Obesity and Related Diseases, 6(6), 591-596. (2010).
Effect of laparoscopic Roux-en-Y gastric bypass surgery on hemoglobin A1c levels in diabetic patients: A matched-cohort analysis
Researchers at Gundersen looked at the effects of obesity surgery on the blood sugar control of patients with type 2 diabetes. They found obese patients with type 2 diabetes who undergo gastric bypass weight-loss surgery are able to significantly improve their blood sugar levels and reduce their use of blood sugar medications. Published in Surgery for Obesity and Related Diseases, 5(1), 4-10. (2009).
Research in bariatric surgery at Gundersen has resulted in numerous publications. Below are just a few of the most recent publications.
