Safety of Early Removal of Chest Tubes After Thoracoscopic Lung Biopsies

Study Overview
=================
Brief Summary
-----------------
prospective study, involves 60 patients underwent thoracoscopic surgery, the patients will be divided into two groups, the first group will undergo early chest tube removal - after three hours, the second group will have late chest tube removal according to the department's protocol. the study aims to prove the possibility and non inferiority for early chest tube removal for thoracoscopic surgeries with non complicated surgical course.

Detailed Description
-----------------
Presence of chest tube post thoracoscopic surgery is associated with increased morbidities like wound infection, pain, and prolong the hospital admission Corse, in the other hand, early chest tube removal is associated with increased the need for recurrent active intervention like pleural tapping for re-accumulated pleural effusion. Method: randomized prospective study includes 60 patients who underwent thoracoscopic lobectomy/segmentectomy/ thoracoscopic mediastinal biopsy. The study will exclude patients with difficult operative course ( intraoperative finding of significant adhesions/ intraoperative injury of the lung parenchyma/ intraoperative bleeding/failure of extubation ) and patient with post operative findings of ( bleeding in the chest tube more than 100 ml in the first hour, persistent air leak, non expanded lung on chest x-ray ) The patients will be divided into two groups, the first group - 30 patients - will undergo chest tube removal after three hours, and the second group will undergo chest tube removal according to the treating department protocol. All patients will be evaluated regarding the pain level - subjective and objective -, admission period, infection, and the need for invasive intervention. The patients will be evaluated during the admission, after one week and after two weeks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: chest tube removal after 3 hours<br>30 patients, post thoracoscopic lobectomy, segmentectomy, thoracoscopic mediastinal biopsy, will undergo chest tube removal after 3 hours. | Procedure: Chest tube removal<br>* chest tube removal post thoracoscopic surgery<br>|
| Active Comparator: delayed chest tube removal<br>30 patients, post thoracoscopic lobectomy, segmentectomy, thoracoscopic mediastinal biopsy, will undergo chest tube removal according to the department's protocol, most probably post operative day 1 (POD1) | Procedure: Chest tube removal<br>* chest tube removal post thoracoscopic surgery<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Non complicated early chest tube removal | the patient with inclusion criteria can undergo early chest tube removal after three hours with no need for chest tube insertion, or pleural tapping for recurrent pleural effusion, | two weeks | 
| Complicated early chest tube removal | Patients who underwent early chest tube removal 3 hours after surgery are more liable for reinsertion of chest tube or active pleural tapping. | two weeks |
