[Thoracic Surgery Without Chest Tube: The Current Situation in Germany].

BACKGROUND

Over the last decades, several techniques have been implemented to reduce the invasiveness of thoracic surgery. Omitting chest tubes can lead to less postoperative pain and a shorter length of hospital stay. This study examines the extent to which German surgeons use the tubeless technique and what experience they have had with it.

MATERIALS AND

METHODS

We conducted a nationwide survey, supported by the German Society of Thoracic Surgery (DGT). A digital questionnaire was sent to all leading thoracic surgeons with DGT membership between July and September 2020.

RESULTS

63 of 161 surgeons (39%) returned the questionnaires. The tubeless technique was used in 1.9% of thoracic surgery procedures performed last year. 59% of hospitals have implemented the technique; 24% of them also performed lung resections that way. The majority of respondents (79%) believe that the tubeless technique causes less postoperative pain; 16% see no advantage. Pleural effusion was ranked as the most important contraindication (76%). All participating surgeons agree that the absence of an air fistula is a prerequisite for performing lung resections using the tubeless technique - commonly checked by an underwater leak test (73%), and/or with a digital drainage system (53%), partially under pressure controlled ventilated lungs. Almost half of the respondents (46%) have not observed any complications using the tubeless technique.

CONCLUSION

Most German thoracic surgeons consider the tubeless technique safe and advantageous over the conventional technique. However, the case load is low and only 59% of the surgeons surveyed have experience with this technique. Randomised clinical trials concerning selection criteria and the procedural pathway may help increase the use.
