Abstract

Surgery on the morbidly obese patients can carry a high risk of perioperative morbidity and mortality due to the unusual stress placed on the physiology of these patients. This risk is often increased because of preexisting cardiorespiratory and metabolic comorbidities. This chapter discusses the preoperative risk scoring systems that are currently used in bariatric surgery to identify and evaluate the morbidity and mortality risks for each patient. These risk scoring systems include the obesity surgery mortality risk score, the bariatric mortality risk, the Edmonton obesity staging system, the metabolic acuity score, and the nomogram for predicting surgical complications. Other useful scoring or classification systems include the cardiac risk assessment for noncardiac surgery system and the American Society of Anesthesiologists physical status classification system. Scoring systems for some comorbidities such as nonalcoholic steatohepatitis (NASH) score have also been utilized to evaluate postoperative changes in bariatric surgery patients. While there is no single ideal risk scoring system that caters to every patient, preoperative risk scoring systems are useful tools in planning a customized approach for each patient.
