Clinical Trial Summary

Pleural empyema : is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria.[1]

Medical thoracoscopy has played a marginal role in the treatment of empyema for a long time, but has become more and more established in recent years. It can be per-formed in analgo-sedation in a bronchoscopy suite. It is minimally invasive and costs are much lower compared to surgical VATS. The diagnostic and therapeutic power seems to be comparable to VATS, since several studies show success rates with medical thoracoscopy between 73 and 100% (2, 3) .

Clinical Trial Description

Study Setting: Assuit university hospital - Chest department. endoscopy unit . the subjects will under go the following :

1. Thorough medical history .

2. Routine hematologic investigations .

3. Pleural fluid aspiration and analyses .

4. Radiological investigation & Chest X ray and CT scan to localize pleural fluid collection and assess the echogenicity of the effusion. & Chest ultrasound. Loculated empyema defined as ultrasonographic presence of empyema loculations with presence of intrapleural septa.

5. Medical thoracoscopy (MT):

Medical thoracoscopy with single-port-of-entry technique will be performed in the bronchoscopy unit under local anesthesia and conscious sedation using midazolam (2 mg) or bethdein.

• To define the point of entry into the pleural cavity, an ultrasound will be carried out.

• vertical incision will be made with the scalpel (usually near the midaxillary line), through the skin and subcutaneous tissue, appropriate to the size of the trocar to be used, usually of approximately 10 mm, parallel with and in the middle of the selected intercostal space.

• Then the trocar will be inserted in a corkscrew motion until the sudden release of resistance (after passing the costal pleura) is felt, while holding the handle of the trocar firmly in the palm of the hand, as index finger is extended.

• Under direct vision with the thoracoscope, introduction of pneumothorax will be performed, and all pleural fluid will be removed, and the pleural cavity will be inspected.

• With the closed biopsy forceps, step by step, fibrinous septae were perforated, the pleural space was irrigated with saline and fluid and fibrinopurulent material were aspirated and removed from the pleural cavity, the entire pleural cavity was inspected and biopsies were obtained from suspicious areas carefully by the biopsy forceps under vision. Multiple lesions were encountered, multiple biopsies were taken & If no lesion, biopsy from parietal pleura was obtained from any sites.

• & Following thoracoscopy, a chest tube (gauge 26-28) was introduced and connected to underwater seal. The wound was then closed around the tube by stitches to fix it in position.

• & After the procedure, chest X- ray PA view was done to show if any complications had happened and to insure inflation of the lung, to determine the size of the residual pneumothorax.

• Vital signs were recorded at appropriate intervals for 24 h. & The rigid thoracoscope and its accessories were sterilized by cold immersion in 2% gultraldhyde (cidex) for at least 30 min.

• An intercostal drain will be placed with underwater seal drainage to drain residual air and fluid from the pleural cavity, allowing the lung to re expand.

• The indications for removal of chest tubes will be absence of air leakage and cessation of fluid flow (100-150 mL daily).

• The patients who would be diagnosed will be blindly randomized to the two study arms :

medical thoracoscopy or tube thoracostomy . ;
