OBJECTIVE. Subepithelial tumors (SETs) in the stomach are usually considered benign. However, some do have potential for malignant transformation, especially when originating in the muscularis propria (MP). Our study aimed to evaluate the clinical efficacy and safety of endoscopic submucosal dissection (ESD) for gastric SETs originating in MP. MATERIAL AND(More)
BACKGROUND AND AIM Gastrointestinal stromal tumors (GISTs), the most common mesenchymal tumors of the digestive tract with potential for malignant transformation, are mainly treated by open surgery or laparoscopic resection. The aim of this retrospective study was to evaluate the clinical efficacy, safety, and feasibility of endoscopic submucosal dissection(More)
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) can successfully resect large lesions en bloc by using a submucosal injection solution, but the cost of currently available submucosal injection solutions is not satisfactory. The authors' aim was to evaluate the feasibility and effectiveness of a thermally sensitive elastin-like polypeptide (ELP)(More)
It is important to understand the differences between emissions from standard laboratory testing cycles and those from actual on-road driving conditions, especially for solid particle number (SPN) emissions now being regulated in Europe. This study compared particle mass and SPN emissions from a heavy-duty diesel vehicle operating over the urban dynamometer(More)
The gastrointestinal tract is the most common location for primary extranodal non-Hodgkin lymphoma (NHL) with cases less commonly found in the intestine. The majority of primary intestinal B-cell lymphomas are exophytic, whereas enteropathy-associated T-cell lymphomas present predominantly as thickened plaques, ulcers or strictures. Crohn's disease (CD) is(More)
OBJECTIVE Extensive surgery is the mainstay of therapy for patients with gastrointestinal mesenchymal tumors (GIMTs) adjacent to the esophagogastric junction (EGJ). However, this modality is invasive and may interfere with anatomic consistency of the digestive tract. Therefore, we evaluated the feasibility, safety, and efficacy of endoscopic submucosal(More)
BACKGROUND AND AIM Peroral endoscopic myotomy (POEM) has emerged as an advanced technique for the treatment of achalasia, and defining the learning curve is mandatory. METHODS From August 2011 to June 2014, two operators in our institution (A&B) carried out POEM on 35 and 33 consecutive patients, respectively. Moving average and cumulative sum (CUSUM)(More)
Modern technologies use NO(2) to promote low-temperature soot oxidation for diesel particulate filter regeneration. In this study, the online aerosol technique of high-temperature oxidation tandem differential mobility analysis is used to study kinetics of soot oxidation by NO(2). Soot particles are exposed to varying temperature and NO(2) mixing ratio(More)
BACKGROUND Gastrointestinal tumors originating from the muscularis propria are believed to have the potential to progress to malignant tumors. The efficacy of 'pre-management' with elastic band or endoloop assistant ligation after initial submucosal dissection in endoscopic enucleation procedure of these tumors was investigated and evaluated. METHODS The(More)
Peutz-Jeghers syndrome (PJS) is a rare, autosomal dominant inherited disorder characterized by gastrointestinal hamartomatous polyps and pigmented mucocutaneous lesions. Intussusceptions and gastrointestinal tract bleeding are frequent complications of PJS caused by larger polyps, but acute pancreatitis and splenomegaly are very rare. Previously, surgical(More)
