BACKGROUND AND AIM: At present, the decision to perform endoscopic resection for treating either papillary early gastric cancer (EGC) or tubular EGC is made according to identical criteria. However, there is controversy in the literature whether the risk of lymph node metastasis (LNM) and submucosal invasion for both disease modalities is equal, and this prompts investigation to clarify this issue. METHODS: The PubMed and Web of Science databases were searched for relevant studies published up to January 2017...

Laparoscopic and endoscopic cooperative surgery for duodenal tumor is the precise oncologic resection procedure and the closure of the defect (1). Non-exposed Endoscopic Wall-inversion Surgery (NEWS) is a novel minimally invasive technique for gastric submucosal mass (SMT) and early gastric cancer having advantageous precision to determine the resection line with no risk of peritoneal contamination (2-5). We describe the NEWS technique that we applied and performed for a small duodenal SMT. This article is protected by copyright...

A 64-year-old woman underwent colonoscopy for abdominal discomfort and a protruded lesion measuring approximately 10 mm was detected in the descending colon. The tumor was entirely covered by normal-appearing mucosa and was regarded as a submucosal tumor (SMT). A small adenomatous polyp was present beside the SMT (Figure 1). For precise histological assessment of the SMT and therapeutic purpose of the coexisted polyp, we performed complete resection of the lesions by endoscopic submucosal dissection.

In recent years, diagnosis of early squamous cell carcinoma (SCC) of the esophagus has been increasingly emphasized. Utilization of image enhanced technology such as narrow band imaging (NBI) and magnification endoscopy allowed detailed examination of the esophageal mucosa. Different patterns of intrapapillary capillary loops (IPCL) have been proven to accurately diagnose and predict the depth of invasion of the tumors. In addition, the application of endoscopic submucosal dissection (ESD) has enabled safe en bloc resection of esophageal lesions...

Achalasia and Treatment of esophageal Adenocarcinoma are commonly associated to surgical resection. Newer technologies in interventional endoscopy gave way to a substantial paradigm shift in the management of these conditions. In the case of achalasia, endoscopic myotomy is rapidly displacing Heller's myotomy as the gold standard in many centers. Early stage neoplasia in Barrett's esophagus (BE) comprising high-grade dysplasia (HGD), intramucosal and, in some cases, submucosal carcinoma is now being treated without the need of esophagectomy...

BACKGROUND AND AIMS: Most submucosal tumors (SMTs) in the esophagogastric junction (EGJ) are irregularly shaped and different from those in the esophagus, where submucosal tunneling endoscopic resection (STER) has been proven effective and safe. However, few reports paid attention to STER for SMTs in the EGJ. The aim of the study was not only to evaluate the effect of STER in patients with SMTs in the EGJ but to analyze the risk factors for failure of en bloc resection. METHODS: A consecutive of 47 patients with SMTs originating from the muscularis propria (MP) layer in the EGJ underwent STER were retrospectively included between September 2012 and December 2016...

Background and study aims Endoscopic submucosal dissection (ESD) offers en bloc resection of lesions, allowing precise pathological assessment. Although possible in ulcerative colitis (UC) patients, the chronic inflammation may increase the procedural risks and reduce the complete resection rate. The aim of this study was to assess the feasibility of ESD for UC and to consider the factors contributing to its technical difficulty. Patients and methods Multicenter experiences of ESD for UC were retrospectively analyzed by reviewing endoscopic videos, pictures, reports, and clinical notes...

BACKGROUND AND AIM: Esophageal endoscopic submucosal dissection (ESD) to resect widespread lesions has increased the incidence of strictures, and some patients develop strictures despite receiving prophylactic locoregional triamcinolone injections. This study evaluated the predictive factors for esophageal stricture formation in patients administered prophylactic triamcinolone injections after ESD. METHODS: This was a retrospective observational study. Of 552 consecutive patients who underwent ESD, those who received prophylactic triamcinolone injections immediately after ESD were enrolled...

BACKGROUND: Patients who have undergone endoscopic resection of early gastric cancers (EGCs) are at risk for metachronous gastric neoplasm. AIM: To determine whether serum level of pepsinogen (PG), a marker of gastric atrophy, can determine which patients who have undergone endoscopic submucosal dissection for EGC are at risk for metachronous gastric neoplasm. We also investigated the effects of Helicobacter pylori eradication on metachronous gastric neoplasm incidence...

Schwannomas are benign tumors derived from Schwann cells and their typical site of origin is the subcutaneous tissue of the extremities. Gastrointestinal localization of Schwannomas is extremely rare and the stomach is the prevalent site. Gastric schwannomas primarily occur in the gastric submucosa and are usually asymptomatic.We present a rare case of a solitary gastric schwannoma in a 51-year old male, which initially manifested with hematemesis by acute upper gastrointestinal (GI) bleeding. The upper GI-Endoscopy revealed a gastric submucosal tumor, 7 cm in size, located in the proximal corpus and fundus...

BACKGROUND/AIMS: Endoscopic submucosal dissection has been widely accepted. At present, the number of antiplatelet (APT) users has been growing. Moreover, because of high risks of thromboembolism, some patients need to continuously receive APT agents. The relationship between hemorrhage and continuous therapy with low-dose aspirin (LDA) remains controversial. MATERIALS AND METHODS: A systematic search was conducted; studies were screened out- if data of no-anticoagulant/APT drugs use and interrupted and continued-LDA use were reported separately...

BACKGROUND AND PURPOSE: Previous studies comparing survival outcomes between patients who did and did not undergo additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) were limited in that the baseline characteristics differed significantly between the groups. We aimed to address this limitation and compared survival outcomes between these two groups using propensity score matching analysis. METHODS: The study enrolled 1969 consecutive patients who underwent non-curative ESD for EGC between 2000 and 2011 at any of 19 institutions across Japan...

BACKGROUND: Surgical resection for esophagogastric junction (EGJ) tumors is more aggressive and worsens the quality of life of the patients and leads to poor prognosis even after surgery compared with tumors in other sites of the stomach. Endoscopic submucosal dissection (ESD) is a widely accepted treatment modality for premalignant lesions and early cancers in the stomach. However, EGJ tumor is one of the most technically difficult lesions to resect by ESD. Therefore, this study aimed to evaluate the therapeutic outcomes of ESD for EGJ epithelial neoplasms and to assess the predictive factors for incomplete resection...

BACKGROUND AND STUDY AIMS : Accurate endoscopic detection of dysplasia in patients with Barrett's esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer...

BACKGROUND AND STUDY AIMS : Cervical esophageal cancer (CEC) is a less common form of cancer and often locally advanced at the time of diagnosis; thus, survival rates for patients with CEC remain poor. However, no reports exist on results of endoscopic submucosal dissection (ESD) for superficial cancer at the cervical esophagus. The aim of this retrospective study was to elucidate the clinicopathological features and clinical outcomes of ESD for superficial CEC. PATIENTS AND METHODS:  ESD was performed on 891 lesions (in 662 patients) for superficial esophageal cancer from January 2008 to December 2015...
