Tähystystoimenpide

Tähystystoimenpide, also known as endoscopy, is a medical procedure that allows doctors to visualize the inside of a body cavity or organ. This is typically achieved using an endoscope, a flexible or rigid tube with a light and a camera attached to its tip. The camera transmits images to a monitor, enabling the medical professional to observe the area in detail.

Tähystystoimenpide can be used for both diagnostic and therapeutic purposes. Diagnostically, it helps identify abnormalities such as inflammation, ulcers, polyps, or tumors. Biopsies, the removal of small tissue samples for laboratory analysis, can also be performed during an endoscopy. Therapeutically, endoscopes can be used to remove polyps, stop bleeding, widen narrowed passages, or deliver medication directly to a specific site.

The specific type of tähystystoimenpide depends on the body part being examined. For example, gastroscopy examines the esophagus, stomach, and duodenum, while colonoscopy visualizes the large intestine. Bronchoscopy is used for the airways, and cystoscopy for the bladder. Laparoscopy, a form of minimally invasive surgery, uses an endoscope inserted through small incisions to view organs within the abdomen.

Patients typically receive sedation or anesthesia before a tähystystoimenpide to ensure comfort and minimize any discomfort. The procedure's duration varies depending on its complexity and the area being examined. Recovery time also differs, with some procedures allowing for same-day discharge while others may require a short hospital stay. Potential risks, though generally low, can include bleeding, infection, or perforation of the organ being examined.
