Advanced therapeutic endoscopy, in particular endoscopic mucosal resection, endoscopic submucosal dissection, per-oral endoscopic myotomy, submucosal endoscopic tumor resection opened a new era where direct esophageal visualization is possible. Combining these information with advanced diagnostic endoscopy, the esophagus is organized, from the luminal side to outside, into five layers (epithelium, lamina propria with lamina muscularis mucosa, submucosa, muscle layer, adventitia). A specific vascular system belonging to each layer is thus visible: Mucosa with the intra papillary capillary loop in the epithelium and the sub-epithelial capillary network in the lamina propria and, at the lower esophageal sphincter (LES) level with the palisade vessels; submucosa with the drainage vessels and the spindle veins at LES level; muscle layer with the perforating vessels; peri-esophageal veins in adventitia...

BACKGROUND AND AIMS: Endoscopic mucosal resection (EMR) is the primary treatment of large laterally spreading colonic lesions (LSL). Residual or recurrent adenoma (RRA) is a major limitation. We aimed to identify a robust method to stratify risk of RRA. METHODS: Prospective multicenter data on consecutive LSL ≥ 20mm removed by piecemeal EMR from eight Australian tertiary centers was included (September 2008 until May 2016). A logistic regression model for endoscopically determined recurrence (EDR) was created on a randomly selected half of the cohort to yield the Sydney EMR Recurrence Tool (SERT), a 4-point score to stratify the incidence of RRA based on characteristics of the index EMR...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

Endoscopic mucosal resection (EMR) is an increasingly popular minimally invasive technique that is used for the management of superficial lesions in the upper and lower gastrointestinal tract. The goal of this article is to describe the indications and technique of EMR, with a focus on the endoscopic management of Barrett's esophagus (BE). The two major EMR techniques-cap EMR and band EMR-will be presented, along with a discussion of their efficacy as well as their integration into the broader treatment paradigm of endoscopic eradication therapy for BE...

BACKGROUND: Endoscopic submucosal tunneling dissection (ESTD) has been proved to be safe and effective for removal of esophageal submucosal tumors (SMTs) and can maintain the mucosal integrity compared with other endoscopic methods. The aim of the study was to estimate the safety and efficacy of ESTD as well as compare its efficacy with thoracoscopic enucleation for esophageal SMTs, which is used increasingly as a minimally invasive approach. METHODS: We retrospectively collected the clinical data of the patients with esophageal SMTs smaller than 40 mm who underwent ESTD or thoracoscopic enucleation at Nanfang hospital between January 2008 and August 2016...

BACKGROUND AND AIMS: Endoscopic therapy is the standard treatment for high-grade dysplasia and some cases of T1a esophageal adenocarcinoma (EAC), but it is not appropriate for deeply invasive disease. Data on the value of EUS for patient selection for endoscopic or surgical resection are conflicting. We investigated the outcome of esophageal EUS for the staging and treatment selection of patients with treatment-naïve, premalignant Barrett's esophagus (BE) and suspected superficial EAC...

PURPOSE: In Japan, the majority of early gastric cancers (EGCs) are now treated with endoscopic submucosal dissection (ESD). Patients with non-curative lesions treated by ESD are advised to undergo additional surgical resection (ASR) based on guidelines from the Japan Gastroenterological Endoscopy Society (JGES) and Japanese Gastric Cancer Association (JGCA). However, many studies have demonstrated that residual cancer and lymph node metastasis are only rarely found in ASR specimens. Here we retrospectively analyzed the conditions that could enable the avoidance of unnecessary ASR...

BACKGROUND: There are limited studies on the dermoscopic features of mucosal melanoma, particularly early-stage lesions. Described criteria include the presence of blue, gray, or white colors, with a reported sensitivity of 100%. It is unclear if these features will aid in the detection of early mucosal melanoma or improve diagnostic accuracy compared to naked-eye examination alone. CASE: An Asian female in her fifties was referred for evaluation of an asymptomatic, irregularly pigmented patch of the clitoral hood and labia minora of unknown duration...

Primary mucosal melanomas of the head and neck are rare and aggressive tumours that arise in the nasal cavity, paranasal sinuses and more rarely, in the oral cavity. The current treatment options include radical surgical resection with adjuvant external beam radiotherapy being offered in high risk patients. Although the latter can improve regional control, it does not reduce overall survival. Elective neck dissection is recommended for nodular oral mucosal melanoma but its role in the clinically node negative neck is controversial...

BACKGROUND AND AIM: Argon plasma coagulation (APC) is a safe alternative treatment for gastrointestinal neoplasms and precancerous lesions. However, the extent of thermal damage after APC is difficult to predict. We investigated the effects of APC on human stomach tissue. METHODS: APC was performed on 10 freshly resected human stomachs which were obtained after total gastrectomy. The effects on tissue were compared across power settings (40, 60, and 80 W), durations (5, 10, 15, 20, and 25 s), and between injection (submucosal injection of normal saline) and control (without injection) groups...

Incidental gastric subepithelial tumor (SET) is frequently found during endoscopy. Although endoscopic ultrasonography (EUS) can provide useful information, its diagnostic accuracy varies. Most of the potentially malignant tumors observed on EUS are hypoechoic lesions. Therefore, we aimed to investigate the diagnostic accuracy of EUS for hypoechoic lesions located in the submucosa or proper muscle layer. We also evaluated various characteristics for potential associations with diagnostic accuracy.A retrospective review was conducted of the medical records of 99 patients who were diagnosed with gastric SET and who underwent EUS with pathologic confirmation between March 2008 and April 2015...
