Minithoracoscope versus Conventional Medical Thoracoscope in Patients with Exudative Pleural Effusion.

BACKGROUND

Thoracoscopy allows visualization of the pleural cavity including diaphragm, visceral pleura, and lungs. It provides the physician with information about the disease extent and it has the ability to get a biopsy from these lesions to differentiate between tumors and fibrotic reactions. This study aims to compare minithoracoscopy and medical thoracoscope in patients with exudative pleural effusion as regards the diagnostic yield, safety, complications, and duration of hospital stay.

PATIENTS AND METHODS

Sixty patients were diagnosed with exudative pleural effusion and were randomly divided into 2 equal groups: Group (1): included 30 patients who underwent minithoracoscopy and Group (2): included the remaining 30 cases who underwent the standard thoracoscope.

RESULTS

Pathological examination of the sample revealed that biopsy size was 2.02 and 1.25 in group 1 and group 2 was respectively with highly statistically significant between both groups ( < .001). Group 1 revealed TB, malignant, chronic nonspecific pleurisy, Staph aureus, Klebsiella, and Pseudomonas in 30% (9), 30% (9), 33.3% (10), 69% (9), 15% (2), and 15% (2) of cases respectively. While group 2 reveled TB, malignancy, chronic nonspecific pleurisy, Staph aureus, Klebsiella, Pseudomonas, and other causes in 40% (12), 23.3% (7), 23.3% (7), 67% (8), 8% (1), 8% (1), and 16% (2) respectively with no statistically significant differences between both groups ( > .05).

CONCLUSION

Minithoracoscopy is well tolerated by patients as minimal pain and early hospital discharge could be achieved by that approach.
