Successful prevention of stenosis after circumferential endoscopic resection of esophageal cancer.

Circumferential resection of a >5-cm longitudinal mucosal defect following esophageal endoscopic submucosal dissection (ESD) is a risk factor for refractory stenosis. Circumferential ESD was performed in 3 patients with 64, 69, and 70 mm longitudinal mucosal defects. A local steroid injection was used to treat the postoperative ulcer, followed by an oral steroid.

Diagnostic Performance of Endocytoscopy for Esophageal Eosinophilia.

Introduction: Eosinophils in the esophageal epithelium are unevenly distributed in eosinophilic esophagitis (EoE). Esophageal eosinophilia (EE) may be observable by endocytoscopy (EC). This study aimed to evaluate the diagnostic performance of EC for the diagnosis of EE.

Novel endoscopic approaches using the endocytoscopy for the target biopsy in esophageal eosinophilia.

Background And Aims: Multiple biopsies are recommended for the diagnosis of eosinophilic esophagitis (EoE) because inflammatory changes are frequently patchy. Reports on EoE using endocytoscopy (ECS) are limited. This present study aimed to assess if diagnostic yield improves by adding ECS on conventional white light imaging (WLI) in patients with esophageal eosinophilia (EE).

Effects of steroid use for stenosis prevention after endoscopic submucosal dissection for cervical esophageal cancer.

Background And Aim: Esophageal stenosis is a serious complication after endoscopic submucosal dissection (ESD) for thoracic esophageal cancer (TEC), and steroid has been applied for stenosis prevention. However, the rate of stenosis and effect of steroid for ESD of cervical esophageal cancer (CEC) remain unknown. The aim was to clarify the rate and managements of post-ESD stenosis for CEC.

A novel scoring system to predict therapeutic intervention for non-variceal upper gastrointestinal bleeding.

Various scoring systems have been developed to predict the need for endoscopic treatment in patients with non-variceal upper gastrointestinal bleeding (NVUGIB). However, they have rarely been applied in clinical practice because the processes are complicated. The aim of this study was to establish a simple scoring system that predicts the need for endoscopic intervention in patients with NVUGIB.

Collision Tumors of Gastric Adenocarcinoma and Mucosa-associated Lymphoid Tissue Lymphoma.

A 65-year-old woman with a history of treatment for splenic marginal zone B-cell lymphoma and gastric mucosa-associated lymphoid tissue (MALT) lymphoma underwent esophagogastroduodenoscopy. A reddish elevated lesion was found in the fundus of the stomach. On image-enhanced endoscopy, several findings, such as glandular structures of varying sizes suggesting well-differentiated adenocarcinoma, pruned blood vessels, and dilated blood vessels in deeper mucosa suggesting MALT lymphoma, were observed.

Comparison of High-Resolution Manometry in Patients Complaining of Dysphagia among Patients with or without Diabetes Mellitus.

Introduction: Dysphagia is a common symptom that occurs in patients with diabetes mellitus (DM). There have been few prospective observational studies on esophageal motility disorders in DM using high-resolution manometry (HRM). This study aimed to clarify the characteristics of esophageal motility disorders using HRM in patients with dysphagia and compare them between DM and non-DM patients.

Subjective Symptoms in Patients with Eosinophilic Esophagitis Are Related to Esophageal Wall Thickness and Esophageal Body Pressure.

Background: Endoscopic ultrasonography (EUS) and high-resolution manometry (HRM) can be used in the evaluation of eosinophilic esophagitis (EoE) for frequent symptoms such as dysphagia. However, the role of these examinations is not clear.

Aims: The aim of this study was to objectively evaluate the subjective symptoms of EoE patients with EUS and HRM.
