Abstract
Background. There is limited literature assessing the outcomes of bariatric surgery in a publically funded, North American, multidisciplinary bariatric program. Our objective was to assess outcomes of roux-en-Y gastric bypass (RYGB) in a publically funded bariatric program through a retrospective review of patient records. Methods. 293 patients spent a median of 13 months attending a multidisciplinary obesity clinic prior to undergoing laparoscopic RYGB surgery. The hospital was a Canadian, publically funded, level 2 trauma center with university teaching services. Results. 79% of the patients were female and the average BMI at first visit to clinic was 55.3 kg/m2. The average decrease in BMI was 19.2 ± 0.9 kg/m2. This was an average absolute weight loss of 56.1 kg or 35.5% of initial weight. The average excess weight loss was 63.4 ± 20.4%. Improvement or resolution of obesity related comorbidities occurred in 65.9% of type 2 diabetics and in 50% of hypertensive patients. Conclusion. Despite this being an unconventional setting of a publically funded program in a large Canadian teaching hospital, early outcomes following RYGB were appropriate in severely obese patients. Ongoing work will identify areas of improvement for enhanced efficiencies within this system.
Highlights
The body mass index (BMI) has been increasing over the last 30 years [1]
Initial weight and BMI were recorded at first presentation to the bariatric clinic
Our study demonstrates that roux-en-Y gastric bypass (RYGB) can be performed safely and effectively on super obese individuals in a publically funded Canadian academic center as part of a comprehensive weight management strategy
Summary
The body mass index (BMI) has been increasing over the last 30 years [1]. Currently, more than 20% of the world population is overweight and approximately 10% are obese [2]. Bariatric surgery is the only evidence-based approach shown to be effective at achieving marked and sustained weight loss in obese individuals [8]. There is limited literature assessing the outcomes of bariatric surgery in a publically funded, North American, multidisciplinary bariatric program. Our objective was to assess outcomes of roux-en-Y gastric bypass (RYGB) in a publically funded bariatric program through a retrospective review of patient records. 79% of the patients were female and the average BMI at first visit to clinic was 55.3 kg/m2. Improvement or resolution of obesity related comorbidities occurred in 65.9% of type 2 diabetics and in 50% of hypertensive patients. Despite this being an unconventional setting of a publically funded program in a large Canadian teaching hospital, early outcomes following RYGB were appropriate in severely obese patients. Ongoing work will identify areas of improvement for enhanced efficiencies within this system
