Combined roentgenological and endoscopic investigation was used to study the state of the esophageal submucous veins. Echography was used for investigation of the gastric subserous veins and esophageal abdominal veins. The results obtained indicate that in the presence of portal hypertension there are two types of shunting: via the esophageal submucous (82%) and subserous (18%) veins. In patients with the predominant affection of the esophageal subserous veins x-ray investigation and endoscopy do not allow correct estimation of the presence and a degree of the gastroesophageal shunt. Echography results enable one to arrive at a correct conclusion in all patients.

Oral submucous fibrosis (OSMF) is a precancerous disorder of the submucosa that causes inflammation and progressive fibrosis, leading to pronounced stiffness and trismus. Chewing betel nuts is a significant risk factor for OSMF in India. Arecoline from betel nuts and copper, which causes fibroblast dysfunction and the development of fibrotic bands, are the main components of betel quid.

Article Synopsis
- - Oral submucous fibrosis (OSMF) is a chronic and progressive condition that leads to stiffness in the mouth and throat, causing difficulties like trismus (inability to open the mouth) and dysphagia (difficulty swallowing), and has various causes related to both local and systemic issues.
- - OSMF shows similarities to other diseases such as scleroderma, which is an autoimmune disorder causing widespread fibrosis, yet they differ in their causes and disease progression, indicating the need for careful differentiation in diagnosis.
- - This review focuses on the causes, symptoms, diagnosis, and management of both OSMF and scleroderma, highlighting their shared and distinct features to improve treatment and patient outcomes.

Background: Peroral endoscopic myotomy is associated with a low risk of adverse events. Mucosal injury is the most common intraprocedural adverse event of peroral endoscopic myotomy. Severe mucosal injury may cause serious consequences, such as esophageal leak and mediastinitis, which affect the outcome of the procedure and prolong hospital stay.

The study focused on the diagnostic value of deep learning-based ultrasound combined with gastroscope examination for upper gastrointestinal submucous lesions and nursing. A total of 104 patients with upper gastrointestinal submucous lesions diagnosed in hospital were selected as the research subjects. In this study, the feed forward denoising convulsive neural network (DnCNN) was improved, and the n-DnCNN model was designed and applied to ultrasonic image processing.
