[Management of Chest Drains after Elective, Thoracoscopic, Anatomical Lung Resections. A Survey in Thoracic Surgical Departments in Germany].

Introduction: The increasing use of minimally invasive techniques along with the introduction of the "Enhanced Recovery After Surgery" (ERAS) guidelines have reduced the perioperative risk of anatomic lung resections. However, the prolonged postoperative air leak still remains one of the major postoperative issues. The purpose of this survey was to evaluate the perioperative management of chest drains and the current clinical practice in treating prolonged air leaks after elective, thoracoscopic, anatomic lung resections in Germany.

Methods: We performed a survey among the thoracic surgical units, which are listed in the Database of the German Thoracic Society (n = 160). Based on the number of resections annually, the centres were divided into high- and low-volume and the results were presented accordingly.

Results: The response rate was 35.6%. Most of the units routinely place a single, 24 Ch. chest drain, which they connect to a digital system on suction. 42.1% of the thoracic units treat a postoperative air leak after the 7th postoperative day. The majority of the surgeons either reduce the suction or use other conservative measures to deal with the air leak. There is no significant difference in the drain management between high- and low-volume centres.

Conclusion: The postoperative hospital stay after an uncomplicated lobectomy has come down to a few days whereas the lower limit of the length of stay has been reduced to 2 days. Nevertheless, 80% of the German thoracic surgeons define a postoperative air leak as prolonged, when it lasts beyond the 5th postoperative day and 65% deal with it only after the 5th postoperative day. The available evidence on this field is limited. New prospective clinical studies are required in order to improve the management of this common complication.
