ABSTRACT
Background The Obesity Surgery Mortality Risk Score (OS-MRS) has been proposed as a user-friendly tool for the assessment and risk stratification of patients undergoing bariatric surgery. Methods Prospectively collected data from 116 patients undergoing Laparoscopic Roux-en-Y Gastric Bypass (RYGBP) at a single university hospital over a period of 18 months from 2008 to 2009 were analyzed to determine the preoperative factors correlating with 90-day mortality. Results The variables used include body mass index =50 kg/m2, male gender, hypertension, patient age =45 years and pulmonary embolus risk, which included previous thrombosis, pulmonary embolus, inferior vena cava filter and right heart failure. Using the 3 risk classes (A, B and C), 97 % of the patients were among the low and intermediate risk groups (A and B). There were zero mortality rates in our study group. Conclusion The analysis confirms that mortality risk for gastric bypass can be stratified based upon independent variables that can be identified before surgery. The OS-MRS is a clinically relevant scoring system and may contribute to surgical decision making in bariatric surgery.
