Sarcopenia predicts poor outcomes in urgent exploratory laparotomy

Background: Emergent laparotomies are associated with higher rates of morbidity and mortality. Recent studies suggest sarcopenia predicts worse outcomes in elective operations. The purpose of this study is to examine outcomes following urgent exploratory laparotomy in sarcopenic patients. Methods: This was a retrospective review of patients in a rural tertiary care facility between 2010 and 2014. Patients underwent a laparotomy within 72 h of admission and had an abdomen/pelvis CT scan were included. Primary outcomes were predictors of morbidity and mortality. Sarcopenia is the lowest quartile cross sectional area of the psoas muscles. Results: Multivariate analysis of 967 patients found that sarcopenic patients had higher mortality, complication rate, were less likely to be discharged home, were more likely to undergo unplanned reoperation, and had a longer length of stay. Increasing abdominal wall fat has favorable outcomes in mortality, discharge destination, and complications. Conclusions: Sarcopenia is measured from CT scans, making it an accessible outcome predictor. In urgent laparotomies, sarcopenia was associated with higher morbidity, mortality, length of stay, and worse discharge destination. (C) 2018 Elsevier Inc. All rights reserved.
