AUGIS member Professor Alan Osborne, who works in Bristol gave a very well-received Royal College of Surgeons Hunterian Oration at the DDF in Liverpool, speaking on ‘Gut Hormones in Bariatric Surgery.’
Professor Osboure described a study to find out what happens to gut hormones after laparscopic RYGB which measured gut hormone changes post-operatively and changes to appetite and satiety. The results showed a significant decrease in hunger. He also looked at insulin resistance, diabetes adding and quality of life studies. He said: “Bypass surgery provides a fascinating model for the study of metabolic surgery but we need to look beyond weight loss and study diabetic outcomes.”
Prof Osborne also said that looking at the economic impact of surgery showed how bariatric operations saved millions of pounds. He referred to a study of 78 people which showed that before operations they had collectively worked 1,023 hours per week whilst after operations this figure rose to 1,611 hours, a 57% increase. Before bariatric surgery, the patients were claiming 32 different benefits but after surgery this dropped to eight. There was a 75% reduction in disability benefit claims.
Prof Osborne moved on to talk about the incidence of obesity in society compared with the number of bariatric trainee positions around the country He estimated that 50 new consultant posts would results in a £75 million economic saving.
In conclusion, he said: “Bariaric surgery is metabolic surgery. It is cost-effective – patients return to a normal quality of life – and it saves lives.”
