Ulcerative colitis is a chronic, inflammatory disease of colon which is rare in Korea. In the course of ulcerative colitis numerous extraintestinal complication may develop on the joints, skin, liver, kidney, vessel, oral cavity and eyes. The most common ocular lesions complicated in patients with ulcerative colitis are episcleritis and iritis. And the cases of retinal vascular disease in associated with ulcerative colitis are extremely rare. We experienced nonischemic central retinal vein occlusion complicated in a patient with ulcerative colitis, who is 32-year-old male and complained decreased visual acuity and metamorphosis.

Objectives: Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.

Wireless capsule endoscopy is currently the outstanding technical innovation in diagnostic gastrointestinal endoscopy. Especially for small bowel diseases this new technique offers several potential advantages over traditional diagnostic tools. The Given Diagnostic Imaging System (Given Imaging Ltd, Norcross, GA) consists of 3 components : the M2A capsule, an external receiving antenna with an attached portable hard drive, and a personal computer workstation for review and interpretation of images. The M2A capsule is a single-use device measuring 11x 26 mm and weighing 3.7 g. It is made of a biocompatible plastic and contains a complimentary metal oxide silicon chip camera, lens, light source, battery, and radio telemetry transmitter. Images are transmitted at 2 per second to an antenna array worn on the abdomen and stored on a Walkman-sized data recorder. The Given system was approved by the Food and Drug Administration in August 2001. The method has chiefly been used in patients with obscure gastrointestinal bleeding, and in some cases has allowed additional diagnoses to be made in comparison with push enteroscopy, with a positive influence on patient management. Contraindications to performance of capsule endoscopy include known or suspected GI obstruction, strictures or fistula, and presence of a cardiac pacemaker, defibrillator, or other implanted electromedical device. The M2A capsule is probably just the first in a long line of wireless endoscopic devices. There are already prototypes of self-propelled devices. Soon to come will real-time imaging, devices to image the proximal GI tract and colon, and devices that can take biopsies or provide therapy.

Nonsteroidal anti-inflammatory drugs (NSAIDs) have analgesic, antipyretic, and anti-inflammatory properties and are widely used for treating musculoskeletal and cardiovascular diseases. Notwithstanding these therapeutic efficacies, gastrointestinal toxicity is the major health problem associated with NSAID use. NSAID-related peptic ulcers are a well-known complication due to direct mucosal injury and cyclooxygenase inhibition. Risk factors for NSAID-related peptic ulcers include a prior history of peptic ulcer; age > 65 years; high-dose NSAID therapy; and concurrent use of aspirin (including low dose), corticosteroids, or anticoagulants. In addition, Helicobacter pylori infection is an independent risk factor; therefore, eradication therapy is recommended in high-risk patients using NSAIDs. Currently, misoprostol, H2-receptor antagonists, proton pump inhibitors, and COX-2 selective inhibitors are used to prevent and treat NSAID-related peptic ulcers. Further, strategic approaches are required through appropriate NSAID use and risk factor stratification to prevent NSAID-related peptic ulcers and associated complications.

Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that utilizes the natural orifices of the human body (e.g., the mouth, anus, vagina and urethra) for surgical procedures. After insertion of an endoscope into organs such as the esophagus, stomach and urinary bladder, these hollow organs are intentionally cut to reach the peritoneal or thoracic cavity to perform various surgical procedures. NOTES is anticipated to become an important part of future medical procedures to treat diverse conditions that cannot endure ordinary surgery with the use of laparotomy or laparoscopy. To take advantage of this new technology, a number of researchers have devoted time and effort to improve both the basic and clinical aspects of NOTES in order to apply this medicinal art fully in the near future. In this review, we evaluate the status of NOTES and attempt to examine the future use of this promising technique that has also been subject to skepticism.
