This study was designed to evaluate the clinical efficacy, safety, and feasibility of endoscopic full-thickness resection (EFR) for gastric submucosal tumors (SMTs) originated from the muscularis propria. Twenty-six patients with gastric SMTs originated from the muscularis propria were treated by EFR between July 2007 and January 2009. EFR technique(More)
The aim of this study was to investigate the management and treatment for complications during and after peroral endoscopic myotomy (POEM) for patients suffering from esophageal achalasia (EA). The data of 119 cases of EA patients who underwent POEM from October 2010 to July 2011 and the complications that arose during the operation, after the operation,(More)
Submucosal tunneling endoscopic resection (STER) can be adequately adopted as an effective treatment for submucosal tumors (SMTs) originating from the muscularis propria (MP) layer at the esophagus and cardia. However, it has been seldom used for gastric SMTs. Our purpose was to evaluate the clinical impact of STER for gastric SMTs arising from the MP(More)
BACKGROUND AND STUDY AIMS Submucosal tunneling endoscopic resection (STER) has become a potential option for the endoscopic treatment of a selected group of patients with submucosal tumors (SMTs) originating from the muscularis propria layer in the upper gastrointestinal tract. The aim of this retrospective study was to analyze the incidence and management(More)
BACKGROUND The technique of endoscopic submucosal dissection (ESD), which was developed for en bloc resection of large lesions in the stomach, has been widely accepted for the treatment of early gastric cancer. It is being used for muscularis propria tumors of the digestive tract and has produced positive therapeutic effects. OBJECTIVE To study the(More)
OBJECTIVE To assess the clinical value of endoscopic submucosal dissection(ESD)for rectal carcinoid tumors. METHODS Endoscopic miniprobe ultrasonography was performed in patients with rectal submucosal tumors under colonoscope. ESD was carried out with the needle knife for lesions diagnosed as rectal carcinoid as following: (1)Fluid was injected into the(More)
BACKGROUND Peroral endoscopic myotomy (POEM) has been developed to provide a less-invasive myotomy for achalasia in adults but seldom has been used in pediatric patients. OBJECTIVE To evaluate the feasibility, safety, and efficacy of POEM for pediatric patients with achalasia. DESIGN Single-center, prospective study. SETTING Academic medical center.(More)
BACKGROUND A circular muscle myotomy preserving the longitudinal outer esophageal muscular layer is often recommended during peroral endoscopic myotomy (POEM) for achalasia. However, because the longitudinal muscle fibers of the esophagus are extremely thin and fragile, and completeness of myotomy is the basis for the excellent results of conventional(More)
Endoscopic submucosal dissection (ESD), a new widely accepted method for treating early gastric cancer, was developed to increase the en bloc rate, especially for lesions larger than 20 mm in diameter. This study aimed to evaluate the efficacy and safety of ESD for colorectal epithelial neoplasms. From July 2006 to December 2007, ESD was indicated for(More)
