JOURNAL FREE ACCESSWe reviewed representative articles which were published after 2000 with regard to magnified endoscopic findings for gastric mucosa and pathology of the stomach. The normal magnified endoscopic findings are different depending upon the pat of the stomach. Briefly, the gastric body mucosa showed a regular honeycomb-lik subepithelial capillary network (SECN) pattern with collecting venules, while the gastric antral mucosa demonstrated a regular coil-shaped SECN pattern. Several articles reported the magnified endoscopic findings for Helicobacter pylori-associated gastritis. With regard to endoscopic diagnosis for early gastric cancer, the correct diagnosis for minute cancers and cancers of flat type could be made by magnified endoscopic findings alone. In addition, this technique was also useful for the preoperative diagnosis of determining horizontal extent of early gastric cancer prior to endoscopic submucosal dissection technique. From the methodological point of view, when we analyze the magnified endoscopic findings, microvascular architecture and surface microstructural change should be evaluated independently. This clarification is essential for establishment of scientific by the magnified endoscopy.View full abstractDownload PDF (14510K) -

JOURNAL FREE ACCESSBackground : Since thromboembolic diseases have increased, the frequency of performing invasive endoscopic procedures on patients taking anti-platelet agents has been increased. We investigated the relationship between the cessation period and endoscopic complications. Method : We analyzed the answers from 81 endoscopists (25 hospitals) with more than 3 years of experience. The questions contain the cessation period of anti-platelet agents (aspirin, ticlopidine) before the invasive endoscopic procedure, and the complications of bleeding or infarction during and after the procedure.Results : Approximately 50% of endoscopists performing biopsies and more than 95% of them performing polypectomies and ESTs replied that they recommended the cessation of antiplatelet agents for 7-10 days before the procedures. Between April 2001 and March 2004, there were 7 cases of abnormal bleeding (including 2 cases of required blood transfusion) and 7 cases with thrombosis (one of them died of cerebral infarction).Conclusion : When invasive endoscopic procedures are performed on the patients taking antiplatelet agents, the sufficient considerations not only for bleeding complications but also for the risk of thrombosis are necessary.View full abstractDownload PDF (7651K) -

JOURNAL FREE ACCESSCase 1 : A 58-year-old woman was hospitalized for blood in the stool with an unknown bleeding part. Bleeding scintigraphy suggested bleeding from duodenal second portion. Side view endoscopy examination revealed an exposed vessel in the duodenal diverticulm. Endoscopic treatment with clip was performed. When CT was performed after the treatment, free air existed in coeliac and retroperitoneal areas. Case 2 : A 69-year-old woman was hospitalized for hemorrhage from erosion in the duodenal diverticulm. Therefore, endoscopic clipping was performed. She had stomachache after the operation. When CT was inspected, free air was admitted in the retroperitoneal area.View full abstractDownload PDF (11768K) -

JOURNAL FREE ACCESSA 68-year-old man presented with tarry stool and anemia. We found sub mucosal tumor (SMT) at the oral side of 2nd portion in the duodenum by endoscope and imaging studies. The SMT was 3cm in diameter with central ulceration, where smoldering hemorrhage was noted. Histological examination showed spindle tumor cells that expressed CD 117 by immunohistochemical studies. We diagnosed this SMT as GIST of the duodenum. When he admitted hospital, the tumor was unresectable because of multiple huge liver metastases. We selected treatment with imatinib mesylate. The remarkable tumor reduction was confirmed with CT and endoscope after treatment. The SMT in the duodenum vanished in 10 month after.View full abstractDownload PDF (8681K) -

JOURNAL FREE ACCESSA 72-year-old woman was referred to our hospital for positive fecal occult blood. Colonoscopy showed a IIa+IIc type tumor in the anal canal. Biopsy was performed and the pathological diagnosis was moderately-differentiated squamous cell carcinoma. The depth of invasion was diagnosed as the submucosal layer by endoscopic ultrasonography. Abdominoper-ineal resection was conducted based on a diagnosis of anal canal cancer. The tumor was diagnosed as moderatery-differentiated squamous cell carcinoma with submucosal invasion (sm3), and was 2.4× 1.6 cm in size. We demonstrate that a careful observation of anal canal is necessary.View full abstractDownload PDF (9020K) -

JOURNAL FREE ACCESSA 7-year-old boy was diagnosed as FAP by double-balloon enteroscopy and APC gene analysis. As anemia was progressing after endoscopic polypectomy of a colon polyp (30mm diameter), the residual polyps of the small intestine and colon were additionally removed by surgery. Because a canceration risk about colonic polyps in this case was very high, total colectomy was recommended. Considering his low age, and capacity of digestion and absorption, we observed the clinical course of polyps at the small intestine carefully. APC gene analysis is useful for an estimate of a phenotype of FAP, but is insufficient for evaluation and treatment. Any endoscopy was indispensable, and particularly, double-balloon enteroscopy was very useful for evaluation and treatment of infantile FAP.View full abstractDownload PDF (11813K) -

JOURNAL FREE ACCESSWe reported a case of Cowden's disease in a 42-year-old woman who visited our hospital for further examination of upper gastrointestinal tract. She had undergone the operation for left breast cancer in the 34-year-old and myoma of uterus in the 37-year-old, respectively. Endoscopic examination revealed multiple small polyps in the esophagus, the stomach and the colon. The biopsy specimen from these polyps showed glycogenic acanthosis in the esophagus and hyperplasia in the stomach. Endoscopic polypectomy of the rectal polyp was performed and its histological findings demonstrated carcinoma in adenoma. She had small keratotic papulosis on the face and extremities, papillomatous lesions in the oral cavity. These findings were compatible to make diagnosis as Cowden's disease.View full abstractDownload PDF (8597K) -

JOURNAL FREE ACCESSDiffuse antral vascular ectasia (DAVE) has recently been paid attention as a cause of chronic gastrointestinal bleeding in patients with liver cirrhosis. We have taken advantage of argon plasma coagulation (APC) for treatment of bleeding from DAVE in 4 patients with liver cirrhosis caused by hepatitis C virus (HCV), and herein report our experiences. In all patients, we were able to successfully cease bleeding from DAVE with APC. No serious complication, including perforation and pneumatosis intestinalis, was observed. After APC treatment, all patients have been followed up at the out-patient clinic. In 3 patients in whom liver function was relatively preserved, no re-bleeding occurred during follow-up. However, re-bleeding developed soon 45 days after the initial APC treatment in one patient, in whom hepatic encephalopathy as well as intractable ascites was noted before APC treatment, and resulted in hepatic failure and death. In conclusion, we propose that APC is an optimal procedure for treatment of bleeding from DAVE in patients with HCV-related liver cirrhosis. However, in patients with severe liver damage, caution of re-bleeding would be required.View full abstractDownload PDF (5215K) -

JOURNAL FREE ACCESSCapsule endoscopy (PillCam TMSB, Given Imaging, Yoqneam, Israel) is a novel noninvasive method allowing visualization of the small intestine. A small video capsule swallowed by the patient, records digital images that are downloaded onto a RAPID® workstation, and the images are viewed as a digital video by a physician. In capsule endoscopy, image acquisition and interpretation is fundamental, however, it is time consuming for untrained physicians. Assuming the capsule transmits images for about 8 h, a total of 57, 600 images will be recorded, and viewing time for the examiner will be between 30 and 60 minutes in our hospital. In spite of technology advantages in capsule endoscopy, diagnostic accuracy depends on the physician's experience. In this paper, we describe the procedure and the point of image acquisition and interpretation in capsule endoscopy.View full abstractDownload PDF (11377K) -
