Esophagogastroduodenoscopy (EGD) or oesophagogastroduodenoscopy (OGD), also called by various other names, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum.
Bronchial brushing is a procedure in which cells are taken from the inside of the airway mucosa or bronchial lesions through catheter-based brushing under direct visualization or fluoroscopic guidance. Flexible brushes are passed through the bronchoscope, and the bronchial surface is gently abraded to obtain the specimen. Various types of ...
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
Esophageal inlet patches are diagnosed by upper endoscopy (esophagogastroduodenoscopy or EGD). Detection of esophageal inlet patches may be improved by the use of specialized imaging techniques such as narrow-band imaging (optical chromoendoscopy).
FLIP is most often performed immediately following upper endoscopy (EGD). [1] EGD helps to rule out a mechanical obstruction as a cause for symptoms, and also provides an estimation on the distance from the incisors to the EGJ. [1] FLIP uses impedance planimetry to measure the cross sectional area of the esophageal lumen. [1]
An endoscopy is usually performed first to evaluate the anatomy, and a guidewire is passed into the stomach past the obstruction. This may also be done fluoroscopically. Bougies are again introduced—this time over the guidewire—in sequentially increasing sizes.
Although most patients tolerate bronchoscopy well, a brief period of observation is required after the procedure. Most complications occur early and are readily apparent at the time of the procedure. The patient is assessed for respiratory difficulty (stridor and dyspnea resulting from laryngeal edema, laryngospasm, or bronchospasm).
