dc.description.abstract |
Obesity is a major health concern both globally and in New Zealand. Obesity and related comorbidities are difficult to treat and are placing a considerable cost burden on the New Zealand health system. Bariatric surgery is a proven treatment for morbidly obese patients with type 2 diabetes. The Roux-en-Y gastric bypass (RYGB) remains the gold standard bariatric procedure due to its strong antidiabetic and weight loss effect. The laparoscopic sleeve gastrectomy (LSG) produces similar weight and antidiabetic effect, while being a simpler procedure with less post-operative complications. Lack of evidence exists about which procedure is most beneficial to obese patients. The Auckland District Health Board (ADHB) offers RYGB and LSG surgery, but no research has been conducted to compare metabolic effect. Methods A survey of the literature looked at the current knowledge about morbid obesity, bariatric surgery and studies comparing RYGB and LSG. A retrospective audit was conducted on 179 patients who completed bariatric surgery at ADHB between 2009 and 2013. Metabolic benefits were compared using categorical and continuous data on already collected information. Results The literature indicated that RYGB and LSG have similar weight loss and comorbidity improvement in the short term of 1-3 years, however longer term studies favour RYGB. Few studies examined the outcomes of LSG longer than 5 years and concerns remain about the long term effectiveness of LSG. More high quality studies are required to fill the knowledge gap about the efficacy of RYGB and LSG. Three key findings came from the audit. When RYGB was compared to LSG there was no difference in weight loss or type 2 diabetes remission at 12 months. Maori and Pacific Island adults who have the highest obesity rates in New Zealand were unrepresented in surgical completion. Conclusion RYGB and LSG are equally effective bariatric procedures in regards to weight loss and improvement of type 2 diabetes, 12 months after surgery. Future research should include longer term studies and research examining barriers which prevent Maori and Pacific Island populations from accessing or completing surgery. |
