Band selection is a common approach to reduce the data dimensionality of hyperspectral imagery. It extracts several bands of importance in some sense by taking advantage of high spectral correlation. In medical imaging, narrow-band imaging (NBI) is an imaging technique for endoscopic diagnostic medical tests, where light of specific blue and green wavelengths is used to enhance the detail of certain aspects of the surface of the mucosa.

Schwannomas are rare, benign tumours arising from Schwann cells, with oesophageal cases representing a small fraction. Their variety of symptoms and nonspecific imaging features often make preoperative diagnosis challenging, frequently requiring immunohistochemical staining for confirmation. We describe the case of a 62-year-old woman with progressive dysphagia, found to have a subepithelial mass at the gastroesophageal junction (GOJ).

To establish a novel laryngopharyngeal reflux model in Bama minipigs excluding concurrent gastroesophageal reflux through endoscopic cricopharyngeal myotomy. Twelve 8-month-old male Bama minipigs were randomly assigned to three groups: Group 1 underwent cricopharyngeal myotomy alone, Group 2 underwent combined cricopharyngeal and lower esophageal sphincter myotomy, and Group 3 served as the control group. Following a one-week acclimatization period, the respective surgical procedures were performed.

Background And Aims: Gastroesophageal reflux disease (GERD) is widespread in the population and is characterized by the risk of developing Barrett's esophagus and associated adenocarcinoma. Key factors in the progression of the disease are not only the frequency and duration of reflux episodes, but also the resistance of the esophageal mucosa to aggressive reflux molecules. Assessment of the state of tight junction proteins, the rate of their recovery under the influence of various treatment regimens is an urgent task for choosing optimal approaches to curing patients with GERD.

Background/aims: We aimed to clarify the clinicopathological characteristics and causes of Barrett's esophageal adenocarcinoma (BEA) with unclear demarcation.
Methods: We reviewed BEA cases between January 2010 and August 2022. The lesions were classified into the following two groups: clear demarcation (CD group) and unclear demarcation (UD group).
