Benefits of gastrointestinal endoscopy
A great advantage of endoscopy is that tiny surgical instruments.
Can pass through the endoscope to perform many functions. This includes taking biopsies, removing growths such as polyps, stopping bleeding from lesions, inserting stents (devices that hold open blocked tubes) and removing gallstones from the bile ducts.
A Nd-YAG laser or argon plasma fibre can also be passed down the endoscope to burn away cancers where appropriate or to เล่นเกมคาสิโน UFABET ทันสมัย ฝากถอนง่าย coagulate bleeding blood vessels. In other imaging methods, including capsule endoscopy, the doctor can only see abnormalities but can do nothing to confirm diagnosis nor treat anything.
Is gastrointestinal endoscopy painful?
Not at all. Modern instruments are very thin and flexible and designed with patient comfort in mind. Patients undergoing gastroscopy and colonoscopy are also offer local anaesthesia by throat spray of lignocaine, as well as gentle sedation with intravenous injections of sedatives and analgesics, or a mild anaesthetic agent, carefully titrated to each individual patient’s comfort. Patients are generally very comfortable throughout their procedures and usually awaken without any memory of having gone through them.
The sedation used in endoscopy is very gentle (unlike the general anaesthesia use in surgery). There are minimal ‘hangover’ symptoms after awakening. In fact, most patients undergo endoscopy as day-cases and are in the Endoscopy Suite or Day Ward for only a few hours at most.
Patients who have morning procedures can, if they wish, return to work by the afternoon. Only in more complex cases will patients need to remain in hospital for a longer period for observation or further treatment.
