Gastrointestinal stromal tumor is rare, which arises from the mesenchymal tissues in the gastrointestinal tract, and it is extremely rare in the appendix. Only a few cases have been found in this location to date. Although the annual incidence of lower gastrointestinal bleeding has been increasing, bleeding related to the appendix is quite rare. We herein present a very rare case of gastrointestinal stromal tumor incidentally found by appendiceal hemorrhage.

Although upper gastrointestinal bleeding is usually segregated from lower gastrointestinal bleeding, and guidelines for gastrointestinal bleeding are divided into two separate sections, they may not be distinguished from each other in clinical practice. Most patients are first observed with signs of bleeding such as hematemesis, melena, and hematochezia. When a patient with these symptoms presents to the emergency room, endoscopic diagnosis and treatment are considered together with appropriate initial resuscitation. Especially, in cases of variceal bleeding, it is important for the prognosis that the endoscopy is performed immediately after the patient stabilizes. In cases of suspected lower gastrointestinal bleeding, full colonoscopy after bowel preparation is effective in distinguishing the cause of the bleeding and treating with hemostasis. The therapeutic aspect of endoscopy, using the mechanical method alone or injection with a certain modality rather than injection alone, can increase the success rate of bleeding control. Therefore, it is important to consider the origin of bleeding and how to approach it. In this article, we aim to review the role of endoscopy in diagnosis, treatment, and prognosis in patients with acute gastrointestinal bleeding in a real clinical setting.

To investigate Helicobacter pylori (H. pylori) eradication rates using second-line bismuth-containing quadruple therapy and to identify predictors of eradication *** study included 636 patients who failed first-line triple therapy and received 7 d of bismuth-containing quadruple therapy between January 2005 and December 2015. We retrospectively demonstrated H. pylori eradication rates with respect to the year of therapy as well as demographic and clinical factors. H. pylori eradication was confirmed by a 13C-urea breath test or a rapid urease test at least 4 wk after the completion of bismuth-based quadruple therapy: proton pump inhibitor, metronidazole, bismuth, and *** overall eradication rates by intention-to-treat analysis and per-protocol analysis were 73.9% (95%CI: 70.1%-77.4%) and 94.5% (95%CI: 92.4%-96.5%), respectively. Annual eradication rates from 2005 to 2015 were 100.0%, 92.9%, 100.0%, 100.0%, 100.0%, 97.4%, 100.0%, 93.8%, 84.4%, 98.9%, and 92.5%, respectively, by per-protocol analysis. A multivariate analysis showed that diabetes mellitus (OR = 3.99, 95%CI: 1.56-10.20, P = 0.004) was associated with H. pylori eradication therapy *** second-line bismuth-containing quadruple therapy for H. pylori infection is still effective in Korea, and diabetes mellitus is suggested to be a risk factor for eradication failure.
