Postoperative chylothorax. Six cases in 2,500 operations, with a survey of the world literature

We have systematically reviewed the literature concerning iatrogenic chylothorax and shall report our personal observations on the subject. Despite an increasing number of thoracic operations, injuries to the thoracic duct are infrequent. Cardiovascular and esophageal procedures are the most frequent causes of chylothorax. Malformations of the thoracic duct and other organs of the mediastinum have often been involved in lymphatic injury. Consequently, we believe that a complicating chylothorax may result from varied causes rather than solely from a surgical error.
