Abstract Back ground: Determining the optimal timing of postoperative oral feeding in trauma patients who have undergone abdominal surgery with small bowel and/or mesenteric injuries is challenging. The aim of this study is to investigate serum lactate as a factor that can predict oral feeding tolerance and prolonged postoperative ileus (PPOI) in patients who underwent surgery for small bowel and/or mesenteric injury due to trauma. Methods: The single center retrospective observational study was conducted on 367 patients who underwent surgery for small bowel and/or mesenteric injury between January 2013 and July 2021. The patient group was divided into two groups based on whether the peak serum lactate was over 2mmol/L (18 mg/dL). In the group of lactate > 2mmol/L, it was divided into prolonged postoperative ileus (PPOI) groups and groups rather than PPOI. Results: Patients in the peak serum lactate > 2 group had tendency to use vasopressors, lower initial systolic blood pressure, larger number of packed red blood cells for 24 h, higher injury severity score, higher PPOI incidence, and a tendency for delayed oral intake tolerance. In peak serum lactate greater than 2 mmol/L group, the lactate normalization time (OR 1.699, p = 0.04), quantity of FFP transfusion for 24 h (OR 1.145, p = 0.012), and creatine kinase (OR 1.001, p = 0.023) were related to PPOI. The lactate normalization time had the highest correlation. Conclusion: In patients undergoing surgical management for small bowel and/or mesenteric injury after trauma, serum lactate normalization time affects oral intake tolerance and prolongs postoperative ileus.

Abstract Background Blunt traumatic gastric perforations in children are rare. Delayed diagnosis will lead to abdominal contamination and may result in morbidity and even mortality. We present a case of an adolescent who sustained blunt abdominal injury in a motocross accident and presented with remarkable hyperdense spherical shaped structures on the computed tomography (CT). Case presentation A 15-year-old boy arrived at the emergency room with an acute abdomen after a motocross accident. A CT scan of the abdomen demonstrated free air and hyperdense round structures in the stomach, pelvic cavity and right paracolic gutter. During emergency laparotomy a traumatic gastric perforation was sutured, a splenic rupture was treated with a vicryl mesh and multiple spherical food scraps were removed from the abdomen. After surgery, the boy clarified that he had eaten a whole bag of colorful and spherical shaped candy just before the accident. Conclusions Traumatic gastric rupture in children is rare but physicians should be aware of this diagnosis in case of blunt abdominal trauma with free air on the CT scan. Gastric contents, in this case candy, can present as hyperdense shaped structures in the abdominal cavity on the CT scan.
