In recent years, cases of diverticular bleeding have become more common. Although identifying the bleeding diverticulum is difficult, it is even more difficult to identify the exposed blood vessels in the bleeding diverticulum. We experienced a case in which we succeeded in directly observing the exposed blood vessels of a sigmoid colon diverticulum using the ultrathin endoscope.

He underwent endoscopic submucosal dissection for hypopharyngeal cancer in parallel with systemic immunotherapy for recurrent renal cell carcinoma, resulting in completely overcoming both malignancies. Endoscopic submucosal dissection is less invasive and can be performed in a shorter duration for treating superficial hypopharyngeal cancer compared with other treatment options, such as radiation therapy, chemotherapy, and surgery.

We examined the use of an ultrathin endoscope for esophageal ESD, which is difficult using conventional endoscopes. A designated transparent hood and ESD knife for ultrathin endoscopes have been developed and clinically introduced.

The Japanese Society of Hospital Pharmacists (JSHP) conducts a nationwide survey annually to analyze the actual situation and generate fundamental information about hospital pharmacy practice in Japan. Using data from this large-scale survey, we described pharmacists' involvement in cancer chemotherapy.

Methods: Eighty-six early gastric cancer lesions complicating AIG in 50 patients were treated by endoscopic submucosal dissection (ESD) at our hospital in 2008-2022.
Introduction The usefulness of traction devices (TDs) in endoscopic submucosal dissection (ESD) for rectal neuroendocrine tumors (NETs) has not been reported. The aim of this study was to investigate the impact of using a TD on the vertical margin (VM) distance in the ESD of rectal NETs. Methods In this single-center, retrospective study, we included patients with rectal NETs who were treated with ESD during 2013-2023.

Methods: We conducted an analysis on the clinicopathological features of individuals with gastric metastases originating from solid organ tumors at the Department of Gastroenterology, Toranomon Hospital, Minato-ku, Tokyo, Japan.
Introduction: Gastric neoplasm of the fundic gland type (GNFG) is a tumor with a good prognosis. However, since it has not been compared with conventional gastric adenocarcinoma (CGA), it is unknown whether it has a good prognosis or requires surveillance after treatment. The purpose of this study was to determine the prognosis and metachronous gastric tumor rates compared with those of CGA.

This exploratory study aimed to identify the risk factors for GNFG.
Methods: We conducted a single-center, retrospective, matched case-control study using medical information recorded at our health management center from January 2014 to July 2023.
Background/aims: : Asymptomatic esophageal eosinophilia (aEE), characterized by eosinophil infiltration in the esophagus without clinical symptoms, has been reported as a precursor of eosinophilic esophagitis (EoE). Nevertheless, no report exists on the long-term clinical course of the disease. Therefore, this study aimed to investigate the long-term clinical course of aEE over 5 years, including the symptomatic conversion rate and the effect of treatments.

Vonoprazan (VPZ) has been available in Japan since 2015. Endoscopic features of proton-pump inhibitor (PPI)-related gastric mucosal changes, including fundic gland and hyperplastic polyps, have been observed. However, the relationship between gastric polyps and VPZ remains unclear.

Symptoms include dysphagia and regurgitation, which are associated with underlying esophageal motility disorders. We herein report a 93-year-old woman with dysphagia diagnosed with symptomatic epiphrenic diverticulum by computed tomography, esophagogastroduodenoscopy, and esophagography.

However, in 2018, the age limitation specified in the package insert was removed. Here, we evaluated the trends in anti-influenza drug prescription and adverse drug reactions (ADRs) reported in pediatric outpatients after revising the oseltamivir package insert as an ecological study.

However, research on outcomes of ARIP applications related to the practice of hospital pharmacists is scarce.
Methods: This study assessed the activities performed by hospital pharmacists in hospitals with 100 to 299 beds, using ARIP acquirement as an indicator, using data from an annual questionnaire survey conducted in 2020 by the Japanese Society of Hospital Pharmacists on the status of hospital pharmacy departments.
Background/aims: We investigated the validity and safety of endoscopic submucosal dissection for gastric tumors by examining shortand long-term outcomes by tumor diameter.
Materials And Methods: Endoscopic submucosal dissection for gastric tumor was performed on 4259 lesions at our hospital between January 2005 and June 2021. [Study 1] Patients were divided into 5 tumor diameter groups: 3751 lesions, ≤30 mm; 366 lesions, 31-50 mm; 106 lesions, 51-75 mm; 24 lesions, 76-100 mm; and 12 lesions, ≥101 mm.
