Endoscopy is a procedure through which a doctor can examine the interior of a patient’s body without having to conduct extensive surgery. A long, flexible tube called an endoscope (also known as a fibrescope) has a lens at one end and a camera at the other. The patient receives the end with the lens. The required area is illuminated by light travelling down the tube (through bundles of optical fibres), which the video camera then magnifies and projects onto a television for the doctor to see. Typically, one of the body’s natural openings, like the mouth, urethra, or anus, is used to implant an endoscope.

Colonoscopy is a procedure used to see into the large intestine, which contains the colon, rectum, and anus. It is a form of endoscopy, which uses a flexible tube with a lit camera introduced into your body as the instrument. Endoscopes come in a variety of varieties for use in various body sections. During a colonoscopy, the colonoscope enters your colon through your rectum and anus. It transfers images of your big intestine’s inside to a screen along the way.

Endoscopic retrograde cholangiopancreatography (ERCP) is a test which combines the use of an endoscope and X-rays. ERCP is a procedure that gastroenterologists use to diagnose and treat conditions involving the liver, pancreas, gallbladder, and bile ducts.

Luminal stenting is a procedure in which the stents are surgically inserted into patients’ GI tracts to increase the lumen (inner space) and remove significant obstructions. Masses in the intestines or other exterior tissues might be obstructions. Stent implantation is often risk-free and is done endoscopically.

Sigmoidoscopy is a procedure in which the sigmoid colon, which is the lowest portion of the is examined during a, a diagnostic procedure. A sigmoidoscope, a thin, flexible tube, is used to accomplish it. The tube is placed into the anus and carefully advanced to the lower section of the colon. It has a tiny light and a camera.

Polypectomy: The surgical excision of a polyp is called a polypectomy. A colonoscope, also known as a thin, flexible, lighted tube, is inserted into the colon and rectum during a polypectomy treatment. The colonoscope not only enables the doctor to view the inside colon, but also to irrigate, vacuum, inject air, and enter the bowel with surgical tools. In order to perform a more thorough inspection and maybe cure any further issues found, the doctor will remove the polyp (and possibly surrounding tissue as well).

EUS: A minimally invasive method called endoscopic ultrasonography (EUS) is used to diagnose conditions affecting the gastrointestinal system and other surrounding organs and tissues. Endoscopic ultrasonography combines the use of an endoscope, a small, flexible tube that is introduced into the digestive tract, and an ultrasound machine.

PEOM: A treatment called peroral endoscopic myotomy is performed to address swallowing abnormalities brought on by muscular issues including esophageal spasms. For esophageal myotomy, POEM uses an endoscope, a small, flexible tube with a camera that is placed into the mouth (peroral). By cutting the muscles, you can avoid them from tightening up and getting in the way of your ability to swallow.
