Total thoracic herniation of the liver: a case of delayed right-sided diaphragmatic hernia after blunt trauma

Abstract

Abstract Background Traumatic diaphragmatic injuries (TDIs) are relatively uncommon and require surgical repair to prevent or address herniation. Three quarters of TDIs are due to blunt thoraco-abdominal trauma. In blunt TDIs, variable clinical presentations and frequent concurrent life-threatening injuries may hinder early recognition and treatment, leading to diagnostic delays, which may result in technically more challenging repairs. Right-sided blunt TDIs are much less common than left-sided ones, are difficult to visualize on imaging studies, are more frequently associated with other potentially lethal injuries, and tend to present more subtly, so that diagnostic delays are more likely. Case presentation We report the diagnosis and elective repair of a large right-sided traumatic diaphragmatic hernia resulting from a distant blunt abdominal injury, describing the techniques used to address the challenges presented by the chronic intrathoracic displacement of the entire liver with the gallbladder, as well as the right side of the colon and part of the duodenum. Conclusions Early diagnosis of right-sided TDIs can be especially elusive. The management of delayed diaphragmatic hernias can be challenging, but with meticulous planning and a flexible surgical approach, a repair can be achieved resulting in good recovery and low risk of recurrence.
