Low skeletal muscle gauge (SMG) significantly predicts higher 30-day and 90-day mortality following emergency laparotomy, with odds ratios of 2.12 and 2.64, respectively. Patients presenting with acute abdominal pain should undergo routine computed tomography reporting of body composition, as low SMG also correlates with prolonged hospital stays. With a study cohort of 1,090 patients, this analysis underscores the necessity of incorporating body composition assessments into risk prediction models for surgical outcomes.
