Introduction:
Post-traumatic diaphragmatic hernias are not commonly diagnosed immediately after the initial trauma. There is a greater prevalence of left hernias due to the fragility or injury in diaphragm muscle and the lack of solid and fixed structures on the left side.
Presentation of case:
A male patient, 30 years old, he was admitted to the emergency department presenting diffuse abdominal pain, vomiting, dyspnea, pain in the left hemithorax with worsening during forced inspiration. After performing X-ray and computed tomography (CT), the presence of organs in the abdominal cavity outside the usual position was evidenced and with discrete deviation. Immediate surgery was performed with posterolateral thoracic access through the sixth left intercostal space combined with left subcostal access. Initially, it was found jejunum, ileum and left colonic flexure and accessory spleen filling the hernial sac.
Discussion:
This report is the first case to report two accessory spleens in manual reduction of herniation between thoracic and abdominal cavities after trauma and percutaneous perforation. The splenectomy performed in both organs occurred due to their advanced ischemia that was due to reduced vascularity.
Conclusion:
The presence of the reported accessory spleen inside the thoracic cavity is only a possible variation within the possibilities in cases of diaphragmatic hernias, which does not modify the surgical procedure in a relevant way.
