tähystystutkimukseen

Tähystystutkimus, commonly known as endoscopy, is a medical procedure used to examine the inside of the body. It involves the use of an endoscope, a flexible or rigid tube with a light and camera attached to its end. This instrument is inserted into the body through a natural opening, such as the mouth, anus, or urethra, or through a small surgical incision. The camera transmits images to a monitor, allowing medical professionals to visualize internal organs and tissues.

Tähystystutkimukset are performed for various diagnostic and therapeutic purposes. They can help detect abnormalities like inflammation, ulcers, polyps, or tumors in organs such as the esophagus, stomach, intestines, lungs, or bladder. In addition to diagnosis, endoscopes can be used for minimally invasive surgical procedures. For instance, small instruments can be passed through the endoscope to take tissue samples (biopsies), remove polyps, stop bleeding, or dilate narrowed passages.

The specific type of tähystystutkimus depends on the area of the body being examined. Examples include gastroscopy (examination of the esophagus, stomach, and duodenum), colonoscopy (examination of the large intestine), bronchoscopy (examination of the airways), and laparoscopy (examination of the abdominal cavity). Patients may be given sedation or anesthesia to ensure comfort during the procedure. Recovery time varies depending on the type of examination and whether any interventions were performed.
