Herein, we describe a rare case of refractory gastric antral ulcers. A woman in her 50 s was admitted to Nagoya City University Hospital with epigastric pain after being diagnosed with gastric antral submucosal tumor at another hospital. Findings from esophagogastroduodenoscopy and endoscopic ultrasound examination revealed that the lesion was a gastric ulcer. The patient had no Helicobacter pylori infection and no recent history of using non-steroidal anti-inflammatory drugs. On the basis of these findings, we diagnosed this as a case of refractory gastric antral ulcer (RGAU)...

INTRODUCTION: Preoperative diagnosis of gastric cancer invasion is not always sufficiently accurate. Diagnostic endoscopic submucosal dissection (ESD) can be performed for the purpose of accurate decision making and to avoid partial treatment vs aggressive over-treatment. We present a patient with the gastric cancer with indeterminate pre-operative diagnosis for depth of the invasion. CASE PRESENTATION: A 70-year-old man presented at our hospital because both anti-Helicobacter pylori (Hp) IGG antibody and serum pepsinogen (PG) levels were classified as positive...

BACKGROUND: Endoscopic radiofrequency ablation (RFA) is a treatment option for early esophageal squamous cell neoplasia (ESCN); however, long-term follow-up studies are lacking. The risks of local recurrence and "buried cancer" are also uncertain. METHODS: Patients with flat-type ESCN who were treated with balloon-type ± focal-type RFA were consecutively enrolled. Follow-up endoscopy was performed at 1, 3, and 6 months, and then every 6 months thereafter...

Endoscopic resection is widely recognized as a first-line treatment for T1 colorectal cancers (CRC), although additional surgical intervention may be indicated based on the risk of lymph node (LN) metastasis. However, risk factors for LN metastasis in T1 CRC not fully established. We investigated the clinicopathological features of T1 CRC and evaluated their association with lymph node metastasis in 133 cases of T1 CRC, consisting of 87 cases with first-line endoscopic resection (EMR) followed by additional surgery and 46 cases with primary surgical resection...

Esophageal stricture occurs at a high rate after endoscopic submucosal dissection, especially after entire circumferential dissection, leading to poor quality of life. This retrospective cohort study evaluated the stricture rate in circumferential mucosal defect cases following modified steroid administration. We enrolled 22 consecutive patients who underwent entire circumferential endoscopic submucosal dissection for superficial esophageal cancer between April 2010 and April 2015 at our hospital. Until January 2013, a systemic steroid-prednisolone-was administered at 30 mg/day and tapered over 8 weeks in the original method group (original group)...

A Dieulafoy's lesion is defined as a dilated, aberrant, submucosal artery that erodes overlying mucosa in the absence of an underlying ulcer, aneurysm or intrinsic mural abnormality. It is a rare cause of upper gastrointestinal (GI) bleed with a very high mortality rate if it goes unidentified. It is most commonly located in the lesser curvature of the stomach but is extremely rare in the oesophagus. We are reporting a 55-year-old man who had massive haematemesis. Emergent endoscopy showed Dieulafoy's lesion in the distal oesophagus...

PURPOSE: Treatment strategies for superficial esophageal squamous cell carcinoma (S-ESCC) are determined mainly on the basis of the depth of invasion. We retrospectively studied the accuracy of the depth of tumor invasion, comprehensively assessed using the Japan Esophageal Society (JES) classification. METHODS: The study group comprised 256 patients who underwent narrow band imaging (NBI) magnifying endoscopy, and endoscopic submucosal dissection for S-ESCC. The depth of invasion of S-ESCC was classified into three groups: EP/LPM, MM/SM1, and SM2...

REVIEW
Dennis Yang, Peter V Draganov
OPINION STATEMENT: "Third space" endoscopy, also commonly referred as submucosal endoscopy, is founded on the principle that the deeper layers of the gastrointestinal (GI) tract can be accessed by tunneling in the submucosal space without compromising the integrity of the overlying mucosa. Peroral endoscopic myotomy (POEM), endoscopic submucosal dissection (ESD), and submucosal tunneling endoscopic resection (STER) are innovative techniques within the field of third space endoscopy in the management of esophageal disorders...

BACKGROUND:  Colorectal endoscopic submucosal dissection (ESD) can be technically difficult in some situations, such as paradoxical movement of the proximal colon. The double-balloon endoscope provides stable endoscopic maneuvering, even in the small intestine. The aim of this study was to assess the outcomes of balloon-assisted endoscopic submucosal dissection (BAESD) of colonoscopically difficult superficial proximal colon tumors. METHODS:  We retrospectively reviewed the records of patients who underwent BAESD of superficial proximal colon tumors where colonoscopic difficulties were encountered, from January 2011 to September 2016...

A 37-year-old man presented to our hospital for early rectal cancer accompanied by mucosal prolapse syndrome. Biopsy confirmed an adenocarcinoma, and endoscopic ultrasonography indicated proximity to the dentate line but no submucosal invasion. The tumor was removed en bloc via endoscopic submucosal dissection without complications, and its margin was free of tumor cells. The total procedure duration was 37 minutes, and the resected specimen measured 23 × 13 mm. There was no recurrence during the 3-year observation period...

Metastasis to the esophagus from a distant primary cancer is a rare manifestation in a patient with a history of oncological disease presenting with obstructive upper gastrointestinal symptoms. Computed tomography of the thorax or esophagogastroduodenoscopy can be non-diagnostic as the disease tends to be submucosal. In such a situation, endoscopic ultrasound (EUS) with fine needle aspiration (FNA) can be directed to characterize and sample the submucosal esophageal lesion. We present a case series of metastatic esophageal strictures diagnosed with EUS and FNA...

Background/Aims: Current guidelines recommend withholding antiplatelets for 5-7 days before high-risk endoscopic procedures. We investigated whether this reduces post-endoscopic submucosal dissection (ESD) bleeding. Methods: Gastric ESD cases with antiplatelets were retorospectively reviewed. Withholding antiplatelets for 5-7 days before ESD was defined as cessation and 0-4 days as continuation. The rate and risk of post-ESD bleeding according to the types and cessation of antiplatelets were assessed...

BACKGROUND/AIM: Laser-based photodynamic endoscopic diagnosis (LPDED) is a type of endoscopic diagnosis that uses the fluorescence caused by the photochemical reaction that occurs when a fluorescent substance is irradiated by a light of a specific wavelength. Although 5-aminolevulinic acid (5-ALA) can detect early gastric cancer (EGC) during LPDED, there is an unresolved issue of the differences in fluorescence intensity among histopathological types of gastric cancer. Thus, the aim of the present study was to assess whether protoporphyrinogen oxidase (PPOX), involved in the activation of protoporphyrin IX, can affect the fluorescence intensity in EGC...

OBJECTIVES: Colorectal endoscopic submucosal dissection (ESD) remains challenging because of technical difficulties, long procedure time, and high risk of adverse events. To facilitate colorectal ESD, we developed traction-assisted colorectal ESD using a clip-and-thread (TAC-ESD) and conducted a randomized controlled trial to evaluate its efficacy. METHODS: Patients with superficial colorectal neoplasms (SCNs) ≥20 mm were enrolled and randomly assigned to the conventional-ESD or TAC-ESD group...

Zenker's diverticulum (ZD), or pharyngeal pouch, is an anatomical defect characterised by herniation of the posterior pharyngeal wall through Killian's dehiscence, and may result in dysphagia and regurgitation. Multiple therapeutic modalities including surgery, rigid and flexible endoscopy have been developed to manage ZD. Although surgical management with open and endoscopically-assisted techniques have historically been the mainstay of ZD treatment, minimally invasive flexible endoscopic techniques, performed under conscious sedation, are increasingly favoured...

Since colorectal endoscopic submucosal dissection (ESD) remains technically difficult, hybrid ESD was developed as an alternative therapeutic option to achieve en bloc resection of relatively large lesions. In this feasibility study, we evaluated the safety and efficacy of hybrid colorectal ESD using a newly developed multifunctional snare. From June to August 2016, we prospectively enrolled 10 consecutive patients with non-pedunculated intramucosal colorectal tumors 20 - 30 mm in diameter. All of the hybrid ESD steps were performed using the "SOUTEN" snare...
