Sarcopenia (a decline of skeletal muscle mass) has been identified as a predictor of poor postoperative outcomes. The impact of sarcopenia in emergency general surgery (EGS) remains undetermined. The aim of this study was to evaluate the association between sarcopenia and outcomes after EGS.

A 3-y (2012-15) review of all EGS patients aged ≥45 y was presented to our institution. Patients who underwent computer tomography–abdomen were included. Sarcopenia was defined as the lowest sex-specific quartile of total psoas index (computer tomography–measured psoas area normalized for body surface area). Patients were divided into sarcopenic (SA) and nonsarcopenic. Primary outcome measures were in-hospital complications, hospital-length of stay [h-LOS], intensive care unit-length of stay, adverse discharge disposition, and in-hospital mortality. Our secondary outcome …
