Background and study aims
Researchers are conducting a study at Zhongda Hospital, affiliated with Southeast University, to improve how they manage air leaks that occur after lung surgery, a common issue that can prolong hospital stays and increase complications. Traditionally, a method called autologous blood patch pleurodesis (ABPP) is used that uses a patient's own blood to seal these leaks. A new method involves two chest tubes and utilizes naturally occurring blood within the chest to seal the air leaks more effectively. This study aims to see if this new double chest tube method can shorten recovery times and reduce complications more than the traditional single-tube method.

Who can participate?
Adults aged 18 years and above diagnosed with non-small cell lung cancer, who are scheduled for lung lobectomy through a minimally invasive technique called Uniportal Video-Assisted Thoracoscopic Surgery (U-VATS)

What does the study involve?
Participants will be randomly assigned to one of two groups: one receiving the new double tube treatment and the other receiving the traditional single tube treatment. The treatment effectiveness will be monitored from the day of surgery until discharge, about 1-2 weeks.

What are the possible benefits and risks of participating?
While there is no direct benefit to participants, the study may help identify more effective treatment methods for future patients. The risks are associated with typical complications of chest tubes used in lung surgeries, such as pain, infection, or air and blood accumulation in the chest, which will be closely monitored.

Where is the study run from?
Zhongda Hospital, Southeast University (China)

When Is the study starting and how long is it expected to run for?
July 2018 to December 2021

Scientific titleEvaluating the effectiveness of double chest tube management utilizing naturally occurring pleural blood for managing prolonged air leaks after uniportal video-assisted thoracoscopic surgery lobectomy: a single-center randomized controlled trial
Study acronymDCTM-PAL
Study objectivesAutologous blood patch pleurodesis (ABPP) utilizes the patient's own blood to effectively seal leaks. Building on the principles of ABPP, this study introduces a novel double chest tube management technique utilizing naturally occurring pleural blood post-uniportal video-assisted thoracoscopic surgery (U-VATS) lobectomy. It is hypothesized that this method may harness the natural healing properties of pleural blood, serving as a biological sealant for air leaks.
Ethics approval(s)

Approved 28/11/2018, IEC for Clinical Research of Zhongda Hospital, Affiliated to Southeast University (87 Dingjiaqiao Gulou District Nanjing, Nanjing, 210009, China; +86 (0)25 8327 2015; zdyyrsk@163.com), ref: 2018ZDKYSB101

Health condition(s) or problem(s) studiedTreatment for postoperative air leakage in patients undergoing U-VAT pulmonary lobectomy
InterventionThe intervention involves a double chest tube strategy for managing post-surgical pleural blood: a 20F chest drainage tube without extra holes and a 19F round type of flexible silicone tube equipped with grooves that run along the tube length. The 20F chest tube, positioned anteriorly in the apex of the pleural cavity, was dedicated to continuous air removal and connected to a water-sealed drainage bottle. The 19F soft tube was placed over the diaphragm and connected to a suction ball to allow intermittent drainage of the naturally occurring blood in the pleural cavity post-surgery.

Participants will be randomly assigned to one of two groups: one receiving the new double tube treatment and the other receiving the traditional single tube treatment. The treatment effectiveness will be monitored from the day of surgery until discharge, approximately 1-2 weeks.

The randomization occurs intraoperatively after the completion of the resection and hemostasis. A member of the surgical team will employ a simple random sampling technique to assign eligible patients to either the control group (with a single chest tube) or the study group (with double tubes). This will be facilitated using SAS statistical software (SAS Institute, Cary, NC, USA), ensuring a randomized allocation of patients in a 1:1 ratio between the two groups.
Intervention typeProcedure/Surgery
Primary outcome measureTime to chest tube removal in full days following lobectomy. The criteria for removing chest tube included: (1) the drainage volume less than 200 ml over the preceding 24 h; (2) absence of intrathoracic hemorrhage or air leakage, and (3) no signs of pleural effusion or atelectasis.
Secondary outcome measures1. The incidence of prolonged postoperative air leakage measured using monitoring by daily observation of the water seal chamber.
2. The total cumulative volume of chest drainage measured using daily counting the records of the chest chamber.
3. The postoperative hospital stay measured by counting at the time of discharge from hospital.
4. The incidence of postoperative complications and mortality measured by counting the records of the electronic hospital charts at the time of discharge from hospital.
