Methods: A 64 year old Chinese gentleman initially presented to the gastroenterology clinic with dyspepsia learn more in 2008. His initial OGD revealed gastritis and small gastric ulcers. Biopsy showed active chronic gastritis, helicobacter pylori and intestinal metaplasia (IM). Over the next 4 years he underwent further 2 OGDs as part screening due to IM. The pathologists raised suspicion of atypical changes in IM, and opinion ranged from indefinite for dysplasia to high grade dysplasia. IEE with FICE and OM was
used in his subsequent management. Results: A 1.5 cm flat (0-IIa) lesion was noted along incisura, demonstrating irregular microvascular and microsurface pattern with clear demarcation line. A diagnosis of early intramucosal gastric cancer was made. The lesion was removed by endoscopic submucosal dissection, and final histopathology – adenocarcinoma staging pT1a. Conclusion: Regular LY2606368 concentration interval endoscopic examination together with IEE is useful in patients with IM in identifying early gastric cancer. The performance of FICE with OM seems comparable to NBI in making such endoscopic diagnosis. Key Word(s): 1. intestinal metaplasia; 2. early gastric MCE公司 cancer; 3. image enhanced endoscopy; 4.

The proximal end of SEMS is usually located in the second portion. The purpose of this study is to compare the mean survival rate and the stent patency depending on different position. Methods: Retrospective review was performed between January 2008 and March 2013 in 13 patients. Thirteen patients received duodenal stent because of malignant gastic outlet obstruction. Complication and clinical outcome was assessed. Results: Out of 13 patients, 4 patients had CBD cancer and 9 patients had pancreatic cancer. SEMS was inserted using Olympus CV-240 endoscope. In 4 patients, the proximal end of SEMS was located at the pre-pyloric ring (Group A). For rest of 8 patients, the proximal end of the SEMS was located at the duodenum bulb (Group B). The patency of stent and mean survival rate were studied between group A and B whose stents were inserted at two different positions. Technical and clinical success rate between two groups had no significant difference. The mean stent patency of group A was 186 days (range, 10 to 310) and mean survival rate was 120 ± 38.96 days.
