Brief Summary
The aim of this study is to evaluate if the presence of abdominal free air on a plain chest radiograph predicts gastrointestinal perforation. We aimed to enroll all patients undergoing abdominal surgery reporting major symptoms and signs suggestive of gastrointestinal perforation (abdominal pain, leukocytosis, fever) within the third postoperative day.

Outcome Measures
Primary Outcomes (1)
prediction of gastrointestinal perforation
• Prediction of the presence of gastrointestinal perforation by the finding of intra-abdominal free air on a chest radiograph after abdominal surgery
Within 3 days from surgery
Secondary Outcomes (1)
time taken for the absorption of intra-abdominal free air
within 3 days from surgery
Study Arms (1)
subjects undergoing abdominal surgery
EXPERIMENTALSubjects who undergone abdominal intervention and reported major symptoms and signs suggestive of gastrointestinal perforation (abdominal pain, leukocytosis, fever) within the third postoperative day. Exclusion criteria: inability to consent to the study, age ≤18 yr, certain or probable pregnancy, inability to remain in upright position for more than 10 minutes.
Interventions
All enrolled patients underwent erect chest x-rays assessment. In all cases the diagnosis of pneumoperitoneum was based upon the plain film identification of subdiaphragmatic air on the upright posteroanterior chest radiograph. All patients were transported from their hospital rooms to the radiology department in wheelchairs and remained in an upright position for more than 10 min before the chest radiographs were obtained. In all cases upright posteroanterior was obtained with the patient standing, using 183-cm distance, 125 kVp, phototimed exposure, and radiographic film with a wide exposure latitude. The disappearance of intraabdominal free gas will be evaluated every 48h and will be defined as the loss of the

- Abdominal surgery and major symptoms and signs suggestive of gastrointestinal perforation within the third postoperative day.
You may not qualify if:
- inability to consent to the study, age ≤18 yr, certain or probable pregnancy, inability to remain in upright position for more than 10 minutes.
