Aim: To evaluate the effect of ranitidine on gastric mucosal changes and on GI bleeding in long distance runners.
Methods: Twenty-four long distance runners (M: 16, F: 8, age: 18.2 +/- 1.5 years) participated in this study. A symptom questionnaire, stool hemoccult test, and upper gastrointestinal (GI) endoscopy were performed on the subjects prior to the study. The subjects took oral ranitidine (150 mg, b.i.d.) for two weeks. The upper GI endoscopy and stool Hemoccult tests were repeated after the treatment.
Results: Twenty-two of the 24 runners had at least one upper GI mucosal lesion before the medication. The Endoscopic improvements were seen in eleven of the 14 cases of erosive gastritis and four of the 5 cases of esophagitis. Six subjects were Heme occult positive prior to the study, but only one was positive after the medication.
Conclusion: Gastric mucosal lesions and GI bleeding in long distance runners seem to be associated to acid-related factors mediated by the high level of regular running. Ranitidine seems to be and effective prophylaxis to prevent gastric mucosal lesions and GI bleeding.

To date, no prospective study has been conducted to compare the safety and effectiveness of endoscopic snare resection with an elastic band (ESR-EB) and endoscopic snare resection with a transparent cap (ESR-C) for treating gastric muscularis propria lesions. We aimed to compare the safety and effectiveness of ESR-EB with those of ESR-C for gastric muscularis propria lesions less than 10 mm in diameter. A total of 64 patients were enrolled prospectively from May 2023 to November 2023 at Shenzhen Hospital of Southern Medical University, the First Affiliated Hospital of Shantou University, and the People's Hospital of Zhongshan City.

Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.

Dendrobium flexicaule (DF) is an endemic plant primarily found in the mountains of central China with important medicinal and edible values. In traditional Chinese medicine, DF has the effects of nourishing stomach and "Yin", and clearing heat. At present, no studies have explored the mechanisms by which Dendrobium flexicaule polysaccharides (DFP) exert pre-protect effects against alcohol-induced gastric mucosal injury.

Endoscopic examination plays a crucial role in the diagnosis of upper gastrointestinal (UGI) tract diseases. Despite advancements in endoscopic imaging, the detection of subtle early cancers and premalignant lesions using white-light imaging alone remains challenging. This review discusses two novel image-enhanced endoscopy (IEE) techniques-texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI)-and their potential applications in UGI diseases.
