Right diaphragmatic hernia after abdominal trauma is a rare injury. Most patients can be asymptomatic, and the diagnosis may be delayed for several years. The treatment of choice involves surgical repair via laparotomy. The authors treated a young patient with transdiaphragmatic herniation of the right hepatic lobe and delayed diagnosis using a laparoscopic approach and accomplished a successful complete repair. The 6-month radiologic follow-up assessment confirmed good results.
