BACKGROUND Although endoscopic submucosal dissection (ESD) is expected to reduce the local recurrence of gastric cancers, we still experience cases of recurrence after an ESD. OBJECTIVE To characterize clinical and pathologic features of cases with local recurrence of early gastric cancer after an ESD. DESIGN A prospective cohort study. SETTING AND(More)
The purpose of this study was to analyze the detectability of colorectal neoplasia with fluorine-18-2-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (FDG-PET/CT). Data for a total of 492 patients who had undergone both PET/CT and colonoscopy were analyzed. After the findings of PET/CT and colonoscopy were determined independently,(More)
OBJECTIVES The narrow-band imaging (NBI) system is a novel technology that enhances the visualization of microvasculature and mucosal patterns. The aim of this study was to assess the reliability of the NBI system for esophageal cancer screening in patients with head and neck cancers. METHODS A total of 142 patients with head and neck squamous cell(More)
OBJECTIVES Lugol-voiding lesions (LVLs), detected by chromoendoscopy using iodine dye in patients with esophageal squamous cell carcinoma (EC) or head and neck squamous cell carcinoma (HNC), are associated with a second primary carcinoma in the other organ. We undertook a cross-sectional and retrospective cohort study to assess the risk for second primary(More)
The objectives of this study were to evaluate the accuracy of endoscopic ultrasonography (EUS) in local and regional staging of early gastric cancer, to analyze the factors influencing the accuracy of EUS, and to reveal the usefulness and problems of EUS in pre-treatment staging of gastric cancer. We examined 105 lesions in 104 patients with histologically(More)
BACKGROUND AND STUDY AIMS Preoperative diagnosis of the pathological grade of intraductal papillary mucinous neoplasms (IPMNs) is difficult. This study aimed to evaluate the accuracy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) with time - intensity curve analysis in differentiating between low or intermediate grade dysplasia (LGD/IGD)(More)
BACKGROUND Our purpose was to evaluate the effectiveness of a newly developed non-invasive traction technique known as thin endoscope-assisted endoscopic submucosal dissection (TEA-ESD) procedure for the removal of colorectal laterally spreading tumors (LST). PATIENTS AND METHODS A total of 37 LST located in the rectum and distal sigmoid colons of 37(More)
BACKGROUND/AIMS Two studies have reported on the superiority of a proton pump inhibitor (PPI) compared with a histamine-2-receptor antagonist for the treatment of artificial ulcers after endoscopic submucosal dissection (ESD), but the optimal dose of PPI remains to be defined. The aim of this study was to evaluate the possibility of reducing the dose of(More)
Endoscopic submucosal dissection (ESD) has been used recently for successful en bloc resection of even large lesions, although no consensus appears in medical literature concerning its application to elderly patients. This prospective cohort study aimed to evaluate the efficacy and safety of colorectal ESD for patients 80 years of age or older. Colorectal(More)
BACKGROUND AND AIMS Although the usefulness of propofol sedation during endoscopic submucosal dissection (ESD) for gastric neoplasms was reported previously, information is limited on its use in elderly patients. We investigated the safety and efficacy of propofol sedation with a target-controlled infusion (TCI) pump and bispectral index (BIS) monitoring(More)
