Colonoscopy is performed to view the rectum and colon, using a colonoscope, which is a long, flexible tube with a camera on the end. Colonoscopy is done to check for colon cancer and other problems in the intestines, as well as to treat and remove polyps. A biopsy can be done during a colonoscopy to look for microscopic evidence of disease.
With the procedure known as gastrointestinal endoscopy, we are able to see the inside lining of the digestive tract. This exam is performed using an endoscope – a flexible fiber optic tube with a tiny camera at the end. The camera is connected to either an eyepiece for direct viewing or a video screen that displays the images on a color TV. The endoscope allows for diagnosis of gastrointestinal (GI) disease and treatment.
EGD with stent placement is a procedure used to treat disorders of the gastrointestinal tract. The doctor passes an endoscope (a thin, flexible lighted tube with a camera on the end) through your mouth to inspect the tissue in your esophagus, stomach and duodenum. For many people with a tumor in their esophagus or duodenum, the area may be narrowed and need to be enlarged for food to get through. During the EGD, a hollow, mesh tube called an esophageal or duodenal stent may be placed. A balloon may also be used to expand the esophagus or duodenum during placement. These treatments should allow food to pass through, though occasionally that also can cause discomfort from the esophagus or duodenum stretched.
Paracentesis is a procedure to take out fluid that has collected in the abdomen (peritoneal fluid). This fluid buildup is called ascites. Ascited may be caused by infection, inflammation, injury, or other conditions such as cirrhosis or cancer. The fluid is taken out using a long, thin needle. Then it is sent to a lab and studied to find the cause of the fluid buildup. Patracentesis also may be done to take the fluid out to relieve belly pressure or pain in people with cancer or cirrhosis.
Endoscopic retrograde cholangiopancreatography, or ERCP, is an endoscopic technique that is used to examine and treat problems in the bile and pancreatic ducts, and the gallbladder. The bile ducts are channels, analogous to plumbing, that drain bile from the liver and gallbladder; the pancreatic ducts drain the pancreas. Both types of ducts empty into the duodenum, which is the first part of the small intestine.
