The lateral chest film and pneumoperitoneum
Abstract:
The erect posteroanterior chest film has long been considered the most sensitive for the detection of intraperitoneal free air. A review of 21 cases of pneumoperitoneum showed three with air present on the lateral but not on the frontal chest radiograph. An explanation for this finding is proposed. We believe that careful evaluation of the lateral chest radiograph for pneumoperitoneum will be helpful in certain cases.

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...
