Robotic Diaphragm Plication

Abstract

Acquired unilateral hemidiaphragm elevation is characterised by dyspnoea, which is typically aggravated when lying down, bending over or during swimming. The most common causes are idiopathic or due to injury to the phrenic nerve during cervical or cardio-thoracic surgery. To date, surgical diaphragm plication remains the only effective treatment. The aim of the procedure is to plicate the diaphragm to restore its tension and thus improve breathing mechanics, increase the available space for the lung and reduce compression from abdominal organs. In the past, various techniques using open and minimally invasive approaches have been described. Robot-assisted thoracoscopic diaphragm plication combines the advantages of a minimally invasive approach with excellent visualisation and freedom of movement. It was shown to be a safe technique which is easy to establish and can significantly improve pulmonary function.
