Frequently asked questions about endoscopy
Endoscopy is the visual inspection of the interior of the body through a small circular tube containing fibre optics. The endoscope is inserted into an orifice allowing a surgeon or physician to view internal organs. Sometimes the procedure is simply for diagnostic purposes, and other times the procedure is used for treatment purposes, such as the removal of a tissue sample or removal of a polyp, or tumour. There are many types of endoscopy.
An endoscope is a medical instrument that allows the surgeon to view the internal organs of a body. The scope has a small diameter "snake-like" insertion tube that enters the body through an orifice and contains optical components that send an image from the inside of the body to a video monitor for the physician to view. A control handle allows the endoscopist to control the direction of the scope and in some cases, permits the actuation of air, water and suction utilities that may be required for the endoscopy procedure.
The indication of different types of endoscopy like upper GI or Lower GI rigid or flexible Air way or Intestinal depends on the type of problem patient have. It depends on the symptom of the patient and the assumption of physician what he wants to see and what is his provisional diagnosis.
Endoscopic retrograde cholangiopancreatography (en-doh-SKOH-pik REH-troh-grayd koh-LAN-jee-oh-PANG-kree-uh-TAH-gruh-fee) (ERCP) enables the surgeon to diagnose disease in the liver, gallbladder, bile ducts, and pancreas. In combination with this process endoscopic sphincterotomy can be done for facilitating ductal stone removal. ERCP is very important for Identification of abnormalities in the pancreatic and biliary ductal system.
ERCP is generally very safe procedure when performed by surgeons who have had specific training and are experienced in endoscopic procedure. Complications are rare, however, they can occur. Some times anaphylactic reactions including rash, pancreatitis due to irritation of the pancreatic duct by the X-ray contrast material or cannula may occur. A reaction to the sedatives can be a complication. Irritation to the vein in which medications were given may cause rashes and a tender lump lasting a few weeks.
Possible complications of endoscopy include bleeding and puncture of the gastrointestinal tract. There is some report of severe damage of biliary tract by inexperienced surgeon even required whiple's procedure. However, such complications are rare. Most people will probably have nothing more than a mild sore throat after the procedure if upper GI endoscopy is performed. There is slight pain and discomfort usually felt after lower GI endoscopy.
