Bariatric surgery associated with better long-term survival

7 January 2015

Obese patients who undergo bariatric surgery have an improved long-term survival, a new study has suggested.

Published in the Journal of the American Medical Association (JAMA), the research focused on significantly overweight patients who were involved in the Veterans Affairs (VA) health system. It found that those who underwent bariatric surgery had a lower all-cause rate of death between five years and ten years after the procedure, compared to those that did not.

The 14-year study analysed 2,500 patients, with 74 per cent of them being male, who all underwent bariatric surgery in VA bariatric centres from 2000-2011. These were then compared to a control group of 7,462 control patients who did not undergo the procedure.

It found that estimated mortality rates for surgical patients were 2.4 per cent a year after the procedure, 6.4 per cent after five years and 13.8 per cent at ten years. Control patients, in contrast, had rates of 1.7 per cent at one year, 10.4 per cent at five years, and 23.9 per cent at ten years.
