About this study
Official title: Association Between Obesity and Outcomes After Surgery for Thoracoabdominal and Isolated Abdominal Gunshot Injuries
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.
Read the detailed description
This was a single-center retrospective observational cohort study of adult patients who underwent surgery for thoracoabdominal or isolated abdominal gunshot injuries at a referral trauma center between 2020 and 2025.
Patients aged 18 years or older were eligible for inclusion. Patients who died in the emergency department, arrived without signs of life, had an Abbreviated Injury Scale score of 3 or greater in another body region, or were transferred from another hospital were excluded.
Patients were categorized according to obesity status. Obesity was defined as a body mass index of 30 kg/m² or higher, and outcomes were compared with those of patients with a body mass index below 30 kg/m².
Data collected from medical records included demographic characteristics, injury-related variables, initial physiological and laboratory findings, perioperative characteristics, blood transfusion requirements, operative duration, gastrointestinal interventions, stoma creation, postoperative complications, need for reoperation, duration of mechanical ventilation, intensive care unit length of stay, total hospital length of stay, and mortality. The shock index was calculated as heart rate divided by systolic blood pressure at emergency department admission.
Postoperative morbidity was defined as any postoperative complication with a Clavien-Dindo grade of IIIa or higher. Multivariable logistic regression analyses were used to evaluate factors independently associated with morbidity and mortality, with obesity included as the primary exposure variable.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Obesity StatusOther
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Other: Obesity Status |
What is being measured
The primary outcome is the main question the study is designed to answer.
Major Postoperative Morbidity
Occurrence of one or more postoperative complications classified as Clavien-Dindo grade IIIa or higher.
Measured: Within 30 days after surgery
