Conceptual developments through colonoscopy.
Fiberoptic colonoscopy is 25 years old this year. Improvement in instruments led rapidly to wide acceptance of colonoscopy in diagnosis and therapy of colorectal diseases. The diagnosis of benign and malignant neoplasms was revolutionized by colonoscopy. The differential diagnosis of inflammatory bowel disease, assessment of its extent and severity, response to treatment, and potential for development of cancer are all made easier by colonoscopy. Colonoscopy has improved the diagnosis of diverticular disease, rectal bleeding, identification of ischemia, and other problems. Therapeutic colonoscopy has radically changed the management of colonic polyps, and colonoscopic polypectomy is now the standard form of treatment for most of these lesions. Treatment of bleeding lesions, decompression of obstruction, and removal of foreign bodies are other examples of therapeutic colonoscopic procedures.
