Schwannomas are uncommon neoplasms that arise from Schwann cells of the neural sheath. Gastrointestinal schwannomas are rare among mesenchymal tumors of the gastrointestinal tract, and only a few cases have been reported to date. Duodenal schwannomas are usually discovered incidentally and achieving a preoperative diagnosis is difficult. Schwannomas can be distinguished from other subepithelial tumors on endoscopic ultrasonography; however, any typical endosonographic features of duodenal schwannomas have not been reported due to the rarity of these tumors. Immunohistochemistry is essential to distinguish schwannomas from gastrointestinal stromal tumors and leiomyomas. We report a case of duodenal schwannoma found incidentally during a health checkup endoscopy. On endoscopic ultrasonography, this tumor was suspected as a gastrointestinal stromal tumor; therefore, the patient underwent laparoscopic wedge resection of the tumor. Histopathology and immunohistochemistry confirmed that the duodenal lesion was a benign schwannoma.

Dieulafoy lesions, vascular anomalies typically found along the gastrointestinal tract, have been viewed as rare and obscure causes of sudden intestinal bleeding, especially in pediatric patients. Since their discovery in the late 19th century, the reported incidence has increased. This is due to an increased awareness of, and knowledge about, their presentation and to advanced endoscopic diagnosis and therapy. Our patient was a three-year-old male, without a complex medical history. He presented to the emergency department with acute hematemesis with blood clots and acute anemia requiring blood transfusion. Endoscopy revealed four isolated Dieulafoy lesions along the lesser curvature of the stomach, which were treated with an epinephrine injection. The Dieulafoy lesion, although thought to be rare, should be considered when investigating an acute gastrointestinal bleed. These lesions have been successfully treated endoscopically. Appropriate anticipation and preparation for diagnosis and therapy can lead to optimal outcomes for the pediatric patient.

The early detection of early gastric cancer (EGC) is important. However, the sensitivity of conventional white light imaging (WLI) in detecting EGC had been reported to range only from 77% to 84%. Although the resolution of endoscopes has been remarkably developed, precancerous lesions such as adenomas and microscopic early cancers are difficult to diagnose with general endoscopy. Linked Color Imaging (LCI) magnifies the differences in color for easy detection. Therefore, it produces a bright image from a distance and is performed for screening endoscopy. The 410 nm wavelength of BLI (Blue Light Imaging) helps to detect cancer by showing microstructure and microvessels in the mucosal superficial layer. This review will focus on the utility of Image enhanced endoscopy (IEE) techniques in diagnosis of gastrointestinal cancer.

Objective : The purpose of this study is to determine a distribution of sasang constitution among dyspepsia patients, and to weigh their symptoms score. Methods : We surveyed symptoms of dyspepsia and QSCCII in one hundred dyspepsia patients who had undergone upper gastrointestinal endoscopy. Results : In distribution of sasang constitution in total dyspepsia patients group and distribution according to the result of endoscopy, ratio and symptoms score of So-Eum-tn were higher than the others. However the differences were not statistically significant. According to symptoms score by age, symptoms score of Tae-Eum-In in patients above 35 years old group was higher than the others. In patients group under 35 years old, symptoms score of So- Yang-In is higher than the others. However in neither group was this statistically significant.

Purpose: This study evaluates the effect of behavioral relaxation training on distress and cancer screening intention of patients with upper gastrointestinal endoscopy. Methods: The research was conducted in a non-equivalent control group posttest design. Data were collected from endoscopy subjects in B city from October to November of 2018. Fifteen minutes of behavioral relaxation training were provided to the experimental group (n=40) and traditional relaxation therapy methods were provided to the control group (n=40). Outcome measures were distress and cancer screening intention of patients with upper gastrointestinal endoscopy. Data were analyzed with a ${\chi}^2$-test, independent t-test, Fisher's exact test with SPSS/PC version 23.0. Results: The objective discomfort (t=8.81, p<.001) of the experimental group was lower than that of the control group; there were no significant differences in the subjective discomfort (t=1.73, p=.088). The cancer screening intention (t=-5.85, p<.001) of the experimental group was significantly higher than that of the control group. Conclusion: Behavioral relaxation training was effective in heightening cancer screening intention. Therefore it can be usefully applied to increase cancer screening intention.

From dye-assisted conventional chromoendoscopy to novel virtual chromoendoscopy, image-enhanced endoscopy (IEE) is continuously evolving to meet clinical needs and improve the quality of colonoscopy. Dye-assisted chromoendoscopy using indigo carmine or crystal violet, although slightly old-fashioned, is still useful to emphasize the pit patterns of the colonic mucosa and predict the histological structures of relevant lesions. Equipment-based virtual chromoendoscopy has the advantage of being relatively easy to use. There are several types of virtual chromoendoscopy that vary depending on the manufacturer and operating principle. IEE plays distinctive roles with respect to histologic characterization of colorectal polyps and prediction of the invasion depth of colorectal cancers. In addition, the newest models of IEE have the potential to increase adenoma and polyp detection rates in screening colonoscopy.

Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive endoscopic technique that has many diagnostic and therapeutic implications. It is a procedure with small but significant life-threatening complications. To ensure the best possible care, minimize complications, and improve the quality of health care, a constant review of the performance of the operator using ideal benchmark standards is needed. Hence, quality indicators are necessary. The American and European Societies of Gastrointestinal Endoscopy have provided guidelines on quality measures for ERCP, which describe the skills to be developed and training to be implemented in performing quality ERCP. These guidelines have divided the indicators into pre-procedure, intraprocedural, and post-procedure measures. The focus of this article was to review the quality indicators of ERCP.
