Procedure Selection in Obesity and Metabolic Surgery Based on EOSS

Procedure Selection in Obesity and Metabolic Surgery Based on the Edmonton Obesity Staging System (EOSS) - a Nationwide German Register-based Cohort Study (StuDoQ MBE)

The Edmonton Obesity Staging System (EOSS) is a more comprehensive measure of obesity-related diseases and predictor of mortality than BMI or waist circumference. EOSS is also important in predicting post - operative outcome and 30-day mortality after metabolic surgery. The aim of this study is to determine whether EOSS could be an indicator for procedure selection in obesity and metabolic surgery.

All patients in Germany, who underwent Sleeve Gastrectomy, Roux-en Y Gastric Bypass and Mini/One anastomosis Gastric Bypass as a primary procedure for severe obesity, are prospectively registered in the German register StuDoQ MBE. Preoperative EOSS by Sharma et al. will be applied to all patients, who were operated between Februar 2015 and July 2017 by two different evaluators. Data collection will include the following: gender, age, body mass index, mobility, comorbidities, ASA score (American Society of Anesthesiologists score) perioperative complications next to Clavien Dindo, readmission rates and 30 - day mortality. Follow-up will be investigated in all patients up to 1 month after surgery. Complications, readmission rates and 30 day mortality will be investigated in relation to EOSS and the surgical procedure performed, to determine whether EOSS could be an indicator for procedure selection in obesity and metabolic surgery.

A cohort of all patients who underwent obesity and metabolic surgery in Germany will be analyzed in relation to preoperative complications

The role of EOSS for the surgical intervention: Mini/One anastomosis gastric bypass for severe obesity

The Edmonton Obesity Staging System (EOSS) is a more comprehensive measure of obesity-related diseases and predictor of mortality than body mass index (BMI) or waist circumference. Its application for the selection of obese patients for obesity surgery has been suggested. This study evaluates the role of the Edmonton Obesity Staging System (EOSS) in predicting postoperative outcome (next to the Clavien Dindo Classification) and 30-day mortality after metabolic surgery.
