12. Impression Acute Gastric Mucosal Lesion R/O Acute Phlegmonous Gastritis

13. Pathology Report (1) Stomach, "antrum", endoscopic biopsy: 1. Acute and chronic gastritis with 1) moderate inflammation 2) moderate activity 3) atrophy (not applicable) 4) no intestinal metaplasia 5) extensive erosion 6) moderate density of Helicobacter pylori-like microorganism, consistent with Helicobacter pylori associated gastritis and acute gastric mucosal lesion 2. Peptic detritus

17. Exercise-associated Gastrointestinal Ischemia 건국대학교병원 소화기내과 이경훈

18. Exercise-associated GI ischemia Colonic ischemia > Gastric ischemia Cause: dehydration, hyperthermia, exhaustion Mechanisms: decreased splanchnic blood flow, acid hypersecretion Treatment: hydration, transfusion, acid blockade Complication (rare): intestinal infarction Prognosis: Good (resume activities without restrictions) Moses F. Cur Sports Med Rep 2005;4:91-5.

19. Exercise-associated ischemic hemorrhagic gastritis Diagnosis: by history taking and EGD finding EGD finding: Acute gastric mucosal lesion (from mild erosion to severe necrotizing ulcer) Symptom: severe epigastric pain, nausea, vomiting Treatment: effective acid blockade Prognosis: quickly recovering symptoms and gastric lesions on EGD finding
