Brief Summary

This retrospective observational study evaluated whether obesity was associated with outcomes after surgery for thoracoabdominal or isolated abdominal gunshot injuries. Adult patients who underwent surgery for these injuries at a referral trauma center between 2020 and 2025 were included. Patients were grouped according to body mass index, with obesity defined as a body mass index of 30 kg/m² or higher. Clinical characteristics, injury-related variables, perioperative findings, postoperative complications, need for reoperation, intensive care unit stay, mechanical ventilation, hospital stay, and mortality were evaluated. The study aimed to determine whether outcomes differed between patients with and without obesity and to identify factors associated with postoperative morbidity and mortality.

Study Arms (1)

Surgically Managed Gunshot Injury Cohort

Adult patients who underwent surgery for thoracoabdominal or isolated abdominal gunshot injuries at the study center between 2020 and 2025. Patients were retrospectively evaluated and classified according to obesity status based on body mass index.

Other: Obesity Status

Interventions

Obesity Status OTHER

Obesity status was determined from body mass index (BMI). Patients with a BMI of 30 kg/m² or higher were classified as having obesity, and patients with a BMI below 30 kg/m² were classified as non-obese. Obesity status was an observed exposure and was not assigned by the investigators.
