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)
No prediction rule is currently available for advanced colorectal neoplasms, defined as invasive cancer, an adenoma of 10 mm or more, a villous adenoma, or an adenoma with high-grade dysplasia, in average-risk Chinese. In this study between 2006 and 2008, a total of 7,541 average-risk Chinese persons aged 40 years or older who had complete colonoscopy were(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 AND STUDY AIMS Recurrence/persistence of symptoms occurs in approximately 20 % of patients after Heller myotomy for achalasia. Controversy exists regarding the therapy for patients in whom Heller myotomy has failed. The aim of the current study was to evaluate the efficacy and feasibility of peroral endoscopic myotomy (POEM), a new endoscopic(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)
