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.
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a minimally invasive procedure for acquiring biopsies in gastric regions that are hard to reach otherwise (e.g. the pancreas). Endoscopic ultrasound EUS-FNA of cystic lesions, followed by liquid cell analysis, has been used as a diagnostic tool for differentiating benign ...
Any additional procedures are performed at this stage. The air in the stomach is aspirated before removing the endoscope. Still photographs can be made during the procedure and later shown to the patient to help explain any findings. In its most basic use, the endoscope is used to inspect the internal anatomy of the digestive tract.
[2] Procedures performed within an endoscopy unit may include gastrointestinal endoscopy (such as gastroscopy, colonoscopy, ERCP, and endoscopic ultrasound), bronchoscopy, cystoscopy, or other more specialized procedures. Endoscopy units may be part of a hospital, where emergency procedures may be performed on ill patients admitted to hospital ...
Cystoscopy is endoscopy of the urinary bladder via the urethra.It is carried out with a cystoscope.. The urethra is the tube that carries urine from the bladder to the outside of the body.
This is because, rigid endoscopy tends to use larger biopsy forceps to take tissue samples from the bowel wall while flexible endoscopy uses small biopsy forceps to take superficial samples. [1] For those with incomplete bowel preparation, the subject can return the next day or the day after next to repeat the procedure.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
An endoscopy is a simple procedure that allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform minor procedures such as tissue biopsies, banding of oesophageal varices or removal of polyps.
