Combination of factors related to the surgical techniques and patient characteristics might explain the pathophysiology behind the diaphragmatic hernias following liver transplantation. Respiratory as well as non-specific gastrointestinal symptoms may be hints for an overlooked diaphragmatic hernia after liver transplantation.
