Cao Q, et al. - In patients undergoing hepatopancreatobiliary surgery for malignancy, researchers evaluated various computed tomography (CT)-assessed sarcopenia indexes as predictors of risk for major complications. For this investigation, they systematically searched Medline/PubMed, Web of Science, and Embase databases to identify relevant studies published before June 2018. Twenty-eight studies were included with 6,656 patients. This meta-analysis found that all commonly used CT-assessed sarcopenia indexes like skeletal muscle index (SMI), psoas muscle index (PMI), muscle attenuation (MA), and intramuscular adipose tissue content (IMAC) can forecast the risk of major postoperative complications. However, there is still no consensus on the cutoffs for these indexes to define sarcopenia.
