Endoscopy

A colonoscopy is a procedure used to diagnose diseases like polyps, colon cancer, colitis and diverticulosis. A colonoscope is a thin, flexible tube which is passed through the rectum into the colon to allow the doctor to look at the lining of the colon. A tiny video camera is attached to the tip of the colonoscope which sends images to a video monitor. If any abnormality is found, a biopsy or polyp removal (polypectomy) may be performed.

A flexible sigmoidoscopy is a procedure used to diagnose diseases like polyps, colon cancer, colitis, diverticulosis and hemorrhoids. A thin, flexible tube is passed through the rectum into the distal half of the colon to allow the doctor to look at the lining of the colon. If any abnormality is found, a biopsy or polyp removal (polypectomy) may be performed.

A gastroscopy is a procedure used to examine the esophagus, stomach and duodenum. The gastroscope is a thin, flexible tube, passed through the mouth into the esophagus, where biopsies of any abnormalities can be taken.

Sometimes conservative measures are not effective to improve hemorrhoid symptoms. Rubber band ligation is the most widely used NONSURGICAL procedure to treat hemorrhoidal bleeding or mild to moderate protrusion.
