AIMS To assess the prevalence and clinical significance of mediastinal emphysema (ME) after esophageal endoscopic submucosal dissection (ESD). METHODS A total of 105 patients in whom assessment of ME was prospectively carried out with multi-detector row computed tomography (MDCT) after esophageal ESD were included in this study. ME was graded as follows:(More)
Endosonography-guided biliary drainage (ESBD) is now gaining acceptance as a useful alternative for the management of obstructive jaundice.(1) At present, ESBD is used mainly to establish an anastomosis between the biliary tree and the duodenum, stomach, jejunum, or esophagus by placing a stent so as to bridge the bile duct and alimentary tract. We herein(More)
OBJECTIVE The indications for endoscopic treatment in early stage cancer of the digestive tract are expanding with the emergence and technical development of endoscopic submucosal dissection (ESD). ESD requires longer term stable sedation than conventional endoscopic procedures due to the necessity of meticulous control of the devices during the procedure.(More)
BACKGROUND Clinical demand for total colonoscopy (TCS) is increasing. Improvement of the cecal intubation rate and shortening of the examination time would expand the capacity for TCS. OBJECTIVE To assess the efficacy of a transparent hood attached to the tip of a colonoscope for cecal intubation in TCS. DESIGN Prospective, randomized, controlled study.(More)
Although many cases of solid cystic tumor of the pancreas (SCT) have been reported, its nature and histogenesis remain controversial. We herein report six cases of SCT, including three cases of noncystic type. A review of 22 cases of noncystic type SCT, including our 3 cases, was carried out to compare their features with those of 173 cases of classic SCT(More)
OBJECTIVE This study was performed to determine and compare the effectiveness and incidence of complications of percutaneous cholecystostomy and gallbladder aspiration in cases of severe acute cholecystitis. SUBJECTS AND METHODS. Fifty-eight patients with severe acute cholecystitis who did not improve after antibiotic treatment were included in this study.(More)
BACKGROUND We histologically evaluated the epithelia of the gallbladder (GB) and bile duct (BD) in patients with anomalous arrangement of the pancreaticobiliary ductal system (AAPB), with regard to the shape of the common BD (CBD). METHODS The GB and BD were studied histologically using surgical materials from 44 patients with AAPB: 27 with a dilated CBD(More)
BACKGROUND AND AIMS To prospectively evaluate the role of contrast-enhanced computed tomography (CE-CT) in the detection of colonic diverticular bleeding (CDB). PATIENTS AND METHODS Consecutive patients who presented with hematochezia and were clinically suspected of CDB were prospectively enrolled. Those who could undergo both CE-CT and total(More)
AIM The aim of the present study was to investigate the efficacy and safety of a newly available enteral WallFlex stent for malignant gastric outlet obstruction (GOO). METHODS Twenty-one consecutive patients with symptomatic (unable to take solids) malignant GOO treated by a WallFlex stent from April 2010 to February 2012 were included and analyzed(More)
BACKGROUND The diagnostic efficacy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) cytology may vary greatly depending on the treatment of the samples obtained and the level of proficiency of the cytopathologist or cytoscreener. METHODS We prospectively evaluated the diagnostic efficacy of the cell block (CB) method and that of smear(More)
