Penetrating abdominal trauma typically presents in an acute manner, and most require emergent intervention due to small bowel, large bowel, and liver injury. Here, we report a 53-year-old man who sustained multiple penetrating intra-abdominal injuries from a nail gun. The patient did not seek medical attention until four weeks after the incident. He presented with worsening abdominal pain and underwent exploratory laparotomy and removal of three intact nails. Fortunately, there were no injuries to the intra-abdominal organs, and the patient had an uneventful post-operative course and was seen in the office after hospital discharge in good condition.
