Background: Organophosphorus poisoning (OP) is one of the common critical conditions in emergency departments in China, which is usually caused by suicide by taking oral drugs. Patients with severe OP have disturbance of consciousness, respiratory failure, toxic shock, gastrointestinal dysfunction, and so on. As far as we know, the perforation of the duodenum caused by OP has not been reported yet.
Case summary: A 33-year-old male patient suffered from acute severe OP, associated with abdominal pain. Multiple computed tomography scans of the upper abdomen showed no evidence of intestinal perforation. However, retrograde digital subtraction angiography, performed via an abdominal drainage tube, revealed duodenal perforation. After conservative treatment, the symptoms eased and the patient was discharged from hospital.
Conclusion: Clinicians should pay close attention to gastrointestinal dysfunction and abdominal signs in patients with severe OP. If clinical manifestation and vital signs cannot be explained by common complications, stress duodenal ulcer or perforation should be highly suspected.
