Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucos...

BACKGROUND/AIMS To evaluate the therapeutic outcomes of the endoscopic submucosal dissection (ESD) technique for the treatment of gastric subepithelial tumors (SETs). METHODS A systematic literature review was conducted using the core databases. Data on the complete resection rates and the procedure-related perforation rates were extracted and analyzed. A random effects model was then applied...

Sporadic nonampullary duodenal adenoma (SNDA) is not easy to find in symptomless patients. SNDA has low incidence and usually occurs singly [1]. Resection of duodenal neoplasm by endoscopic submucosal dissection (ESD) has been increasingly reported [2]; however, resection of triple SNDAs has not been reported before, to our knowledge. Here we describe a case of successful ESD for triple SNDAs u...

AIM To examine the association between white opaque substance (WOS) and histologically verified lipid droplets in colorectal epithelial neoplasms. METHODS We reviewed colonoscopy records at our institution from 2014 to 2016 and identified cases of endoscopically or surgically resected colorectal epithelial neoplasms observed by magnifying narrow-band imaging (M-NBI) colonoscopy. Immunohistoch...

OBJECTIVE To investigate, in a porcine tongue model, the lesions created by coblation to define the optimal application of this method in treating the enlarged tongue base in patients with obstructive sleep apnea syndrome. STUDY DESIGN A prospective, experimental animal study. SETTING Military medical center. SUBJECTS AND METHODS Fifteen fresh porcine tongue specimens were injected with n...

BACKGROUND Endoscopic submucosal dissection (ESD), an endoscopic technique used for treatment of gastric superficial lesions, has been gaining importance on western countries. Procedural times have an impact on various outcomes. AIM To define which factors from patients, lesions and procedure can predict longer procedural times. METHODS In a cohort of 127 lesions resected by ESD with IT-kni...

BACKGROUND/AIMS Techniques for endoscopic evaluation of gastrointestinal subepithelial lesions include conventional endoscopy, jumbo biopsy, endoscopic ultrasonogrphy (EUS), EUS-guided fine needle aspiration, and endoscopic submucosal resection. However, these procedures have many limitations, such as low diagnostic yields and high complication rates. We therefore evaluated the diagnostic yield...

a new endosurgical approach to the resection of giant rectal lesions Transanal surgical and advanced endoscopic resection procedures have the potential to provide complete and successful eradication of rectal lesions [1–3]. However, both approaches have limitations in terms of practicability and safety [3–5]. Transanal submucosal endoscopic resection (TASER) is a new endosurgical approach, whic...

Abstract Submucosal deep invasion of gastric cancer (T1b2; depth submucosal ? 500 ?m) is a risk factor for lymph node metastasis and, thus, one the criteria curative treatment. Our aim was to evaluate specific influence endoscopic dissection (ESD) on prognosis patients with T1b2 cancer. This retrospective analysis 248 consecutive patients, 252 pT1b2 lesions, who underwent ESD prior additional s...

Purpose: Lymph node metastasis is an important prognostic factor in patients with early gastric cancer. Therefore, we analyzed the predictive factors for lymph node metastasis in submucosal gastric cancer and explored the feasibility of minimally invasive surgery. Methods: The clinicopathological features of 317 patients with submucosal gastric cancer, who underwent radical gastrectomy with lym...
