OBJECTIVES Endoscopic submucosal dissection (ESD) in the duodenum is challenging. The water pressure method (WP-ESD) has been developed with a decreased rate of perforation. However, details of perioperative adverse events of WP-ESD are unknown. The purpose of this study was to clarify the frequency and related factors of fecal incontinence and oral regurgitation during WP-ESD. METHODS A chart-based retrospective analysis was performed on 43 patients who underwent duodenal WP-ESD. The saline vol...
BACKGROUND AND AIMS Efficacy of endoscopic balloon dilation (EBD) for intestinal strictures in patients with Crohn's disease (CD) receiving anti-tumor necrosis factor alpha antibodies (anti-TNF) as maintenance therapy is unclear. We investigated the long-term efficacy and safety of EBD for intestinal strictures in patients with CD receiving anti-TNF. METHODS We retrospectively analyzed data from patients with CD who received anti-TNF as maintenance therapy from 2008 to 2017, underwent EBD, and w...
OBJECTIVES Photodynamic therapy (PDT) is an optional salvage treatment for local failure of esophageal squamous cell carcinoma (ESCC) after chemoradiotherapy; however, local failure after PDT sometimes occurs. In such cases, second PDT is sometimes attempted, but its outcomes remain unclear. This study aimed to evaluate the efficacy and safety of second PDT. METHODS We enrolled patients who underwent PDT for local failure of ESCC after chemoradiotherapy. We retrospectively evaluated local-comple...

Splenic sclerosing angiomatoid nodular transformation (SANT) was first described as a distinct pathological entity in 2004 by Martel et al.1 SANT is an extremely rare and benign vascular lesion. Common differential diagnoses include lymphoma, metastasis, and angiosarcoma.2 However, it is difficult to differentiate splenic tumors preoperatively by imaging.3 Recently, it has been reported that endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful in differentiating various abdomi...
Protracted percutaneous endoscopic gastrostomy (PEG) tubes can cause excoriation of the entry site secondary to track dilatation and leakage [1]. A 66-year-old gentleman had PEG tube inserted prior to definitive chemo-radiotherapy for squamous cell carcinoma of the oropharynx eleven years before. He has been on PEG feeds since then as dysphagia persisted due to a tight non-dilatable post-cricoid stricture.

The revised 2014 Japanese Guidelines for Gastric Cancer Screening approved gastric endoscopy for use in population-based screening. Thus, it is expected that gastric cancer will be detected earlier, and gastric cancer mortality further decreased, with the widespread use of endoscopy and H. pylori eradication therapy. However, due to an increasingly aging population and relatively low gastric cancer screening rates, gastric cancer remains the leading cause of cancer death in Japan. While the era ...
