Abstract:

Abstract Background and study aims Recent advances in endoscopic equipment and diagnostic techniques have improved the detection of dysplasia in the inflamed mucosa of patients with ulcerative colitis (UC). However, it remains difficult to endoscopically identify flat-type dysplasia which has been formerly recognized as invisible dysplasia. Patients and methods In this retrospective, single-center study, we endoscopically identified 10 cases of flat-type-predominant dysplasia by targeted biopsy among 38 intramucosal dysplasia lesions from patients with UC who underwent surgical or endoscopic r

Abstract:

Abstract Adenocarcinoma and dysplasias are recognized complications of Barrett mucosa. In the past, the treatment for this carcinoma was esophagectomy. However, new techniques, including endoscopic mucosal resection, sometimes replace esophagectomy and are becoming standard procedures in clinical practice, not just in major medical centers. Pathologists must learn to handle these specimens, which have extensive artifacts. Also, Barrett mucosa has duplicated stromal layers beneath the mucosa that include a new lamina propria and a new muscularis mucosae. We must be aware of these peculiarities

Abstract:

Barrett’s Esophagus is a common condition associated with chronic gastroesophageal reflux disease. It is well known that it has an association with a higher incidence of esophageal adenocarcinoma, but this neoplastic transformation is first preceded by the onset of low and high-grade dysplasia. The evaluation of low grade dysplastic esophageal mucosa is still controversial; although endoscopic surveillance is preferred, several minimally invasive endoscopic therapeutic approaches are available. Endoscopic mucosal resection and radiofrequency ablation are the most used endoscopic treatments for

Abstract:

Abstract Background and study aims Accurate endoscopic detection of dysplasia in patients with Barrett’s esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer

Barrett’s esophagus is associated with an increased occurrence of mucosal dysplasia and adenocarcinoma in the specialized glandular mucosa, with a 30- to 52-fold increase in the occurrence of esophageal cancer compared with the normal population.

Barrett’s esophagus (BE) is a premalignant condition. The incidence of adenocarcinoma in BE has been reported to be between 0.1-3%. Dysplasia in BE is patchy and extensive biopsy sampling is labor intensive, low yield and does not eliminate the sampling error completely. Volumetric laser endomicroscopy (VLE) is expected to enable endoscopists to do targeted biopsy of dysplastic/cancerous lesions (not visible on white light endoscopy) among patients with BE.

Abstract:

Introduction. When examining the oral mucosa (OM) in the presence of an inflammatory process, the initial signs of malignancy are not always visible. Amid an inflammatory infiltrate, benign changes such as epithelial hyperplasia (EH), epithelial dysplasia (ED) of varying severity, and squamous cell carcinoma (SCC) can be hidden. The aim of the paper was to study the proliferative activity of epithelial cells of the OM, TERT expression, and amplification of telomerase TERC gene in the development of epithelial hyperplasia, dysplasia, and SCC.

At 1, 3, 5, 6, and 8 months after the start of feeding, eight rats were randomly chosen from each group, and gastric mucosa tissues were removed for histopathological analysis.

Abstract:

An important goal for the surgeon after performing proctocolectomy for ulcerative colitis is the preservation of continence, with the formation of a pelvic ileal pouch. In most patients who have required this procedure, clinical results have been satisfactory. In recent years, it has become appreciated that many patients with a satisfactory surgical result are still at risk for pouchitis and pouch neoplasia. This is not surprising because creation of a pouch leads to an environment characterized by stasis, with associated mucosal adaptive changes. In some patients, the ileal mucosa in the pouc

Abstract:

Abstract The diagnosis of dysplasia and early neoplasia in Barrett’s esophagus by conventional endoscopy is based on a four- quadrant random biopsies protocol that is prone to sampling errors. Novel endoscopic techniques have been developed to enhance the detection of premalignant and malignant lesions by real time assessment of microvasculare architecture and mucosal structure. Chromoendoscopy with magnification has improved the visualization of lesions, but the dye application impairs a clear evaluation of vascular network. Narrow band imaging endoscopy enhances vascular imaging by using nar

Here, we developed a rat model of candidiasis with diabetes progressing to mucosal proliferation. Diabetes was induced in thirty rats by single intravenous administration of alloxan.

Barrett’s esophagus is a condition in which the normal squamous lining of the esophagus has been replaced by columnar epithelium containing intestinal metaplasia induced by recurrent mucosal injury related to gastroesophageal reflux disease. Barrett’s esophagus is a premalignant condition that can progress through a dysplasia-carcinoma sequence to esophageal adenocarcinoma. Multiple endoscopic ablative techniques have been developed with the goal of eradicating Barrett’s esophagus and preventing neoplastic progression to esophageal adenocarcinoma.
