This article presents the findings of a study conducted in Uruguay to determine the prevalence and endoscopic-histological correlation of premalignant gastric lesions. The study included 102 patients who underwent upper endoscopy and gastric biopsies. The prevalence of chronic atrophic gastritis (CAG) was found to be 38.2%, while intestinal metaplasia (IM) had a prevalence of 31.4%. The endoscopic-histological correlation for CAG and IM was low, indicating the need for biopsy for diagnosis in all cases. The study also identified a low proportion of high-risk stages of premalignant lesions. [Extracted from the article]

The article discusses the use of positive capsule endoscopy to diagnose and treat the small-bowel disorders. Topics include the emergence of spiral enteroscopy as an alternate method for enteroscopy, the assessment of the impact of capsule endoscopy in patients with double-balloon enteroscopy (DBE) and obscure gastrointestinal bleeding (OGIB) conducted by L. C. Fry and colleagues, and the challenges posed by the diagnosis of Crohn's disease.

The article presents a case study of a 68-year-old man presented with obscure occult gastrointestinal bleeding and was referred to emergency department for capsule endoscopy. The patient developed melena after he underwent into capsule endoscopy and was required for blood transfusion. The article discusses enteroscopy, metastatic renal cell cancer, and intraluminal small-bowel metastases.
