Abstract:
Pneumothorax, pneumomediastinum, pneumopericardium, and subcutaneous emphysema have been described as complications of laparoscopy. This study evaluates the incidence and significance of these extra alveolar collections of air. We found that pneumomediastinum with or without pneumothorax was not associated with significant morbidity and is more likely after laparoscopic fundoplication than other laparoscopic surgeries. The presence of pneumomediastinum after fundoplication is a normal finding. However, pneumothorax has clinical significance and should be considered pathological.

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Pneumothorax-II
Clinical Manifestations:
Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
