COS, Ana Isabel de et al. Obesity associated risk using edmonton staging in bariatric surgery. []. , 31, 1, pp.196-202. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2015.31.1.8097.

With a prevalence of Morbid Obesity of 1,2% of the Spanish population, the current criteria for Bariatric Surgery do not classify patients taking into consideration co-morbidities or functional status. We need new staging systems useful in predicting mortality and able to support prioritizing treatments. Aim: Applying Edmonton staging system to patients awaiting Bariatric Surgery. Method: Data collected from 81 patients from 2011- 2013 after pre-surgery protocol. Weight, height, waist, BMI, biochemical parameters and blood pressure are registered. Also taken down are hepatic, renal, osteoarticular diseases, sleep-apnea syndrome and/or gastro-oesophageal reflux, if present. Edmonton staging of ten variables is applied to each patient. Results: 81 patients: 67% women, average age 47y, 18% below 30y. Average BMI of 47, 90% of patients have a BMI >40.34% of patients show sleep-apnea syndrome and 25% gastro-oesophageal reflux. 9% of the patients have a BMI >45, diabetes mellitus and sleep-apnea syndrome. Applying the Edmonton Staging, nine patients (11%) are in the highest risk range (stage 3), 70% are in the high-risk range (stage 2) and 15 patients (18%) are included in the low-risk range. No patient was found to be in stage 0 without obesity risk factors. Conclusions: The Edmonton staging system provides us with information on presence or extent of co-morbidities that guide decision making in individuals. The mortality- predictive ability of Edmonton proposal could help to assist in determining the urgency of Bariatric Surgery and establish better criteria to prioritize these group of patients.
