OBJECTIVES We sought to evaluate the safety, efficacy, and feasibility of endoscopic sphincterotomy plus large balloon dilation (ESLBD) and to compare procedural time and fluoroscopy time of ESLBD with those of endoscopic sphincterotomy (EST) alone for patients with large bile duct stones. METHODS Retrospective analysis. RESULTS A total of 101 patients(More)
BACKGROUND/PURPOSE It has been reported that circulating tumor cells (CTCs) can be used to predict survival in metastatic breast cancer. In this preliminary study, we examined the level of CTCs in pancreatic cancer (PC) patients to elucidate whether we could predict survival in PC. METHODS The eligible subjects, at Tokyo Medical University Hospital, were(More)
BACKGROUND Tubular plastic and metal stents have inherent shortcomings when used for transenteric drainage of fluid collections. OBJECTIVE To evaluate a novel lumen-apposing, self-expandable metal stent for EUS-guided drainage of pancreatic pseudocysts and the gallbladder. DESIGN Retrospective case series. SETTING Tertiary-care academic medical(More)
BACKGROUND AND STUDY AIMS The aim of this prospective study was to compare endoscopic ultrasonography-guided Trucut needle biopsy (EUS-TNB) with EUS-guided fine-needle aspiration biopsy (EUS-FNAB) using 19- and 22-gauge needles for biopsy from different sites in patients with solid pancreatic cancers. PATIENTS AND METHODS Sixteen consecutive patients with(More)
The development of equipment and contrast agents for ultrasound imaging has contributed to major breakthroughs in the diagnosis of pancreatic tumors. We aimed to determine the diagnostic effectiveness of contrast ultrasound with Levovist, using the Agent Detection Imaging (ADI) technique, in 50 patients with pancreatic tumors. We studied 50 cases of(More)
BACKGROUND Post endoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis is the most common complication of ERCP, which can occasionally become serious or fatal. This preliminary study was to prospectively evaluate the efficacy of a temporary unflanged pancreatic duct stent (PS) to prevent post-ERCP pancreatitis. METHODS A total of 64(More)
There have been a few previous reports on attempted double-balloon endoscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anastomosis and an intact papilla. This study was designed to evaluate the usefulness of DBE-assisted ERCP in patients with Roux-en-Y anastomosis and an intact papilla of Vater. Thirteen(More)
BACKGROUND Endoscopic ultrasonography (EUS)-guided pancreatic drainage has been advocated as a rescue treatment for management of patients in whom retrograde access to the pancreatic duct (PD) is technically unsuccessful. The aim of the present study was to evaluate the feasibility and efficacy of EUS-guided drainage for failed endoscopic retrograde(More)
Minimally invasive interventions for choledocholithiasis are preferable in elderly patients because they tend to have multiple underlying disorders or a decreased activity of daily living. Endoscopic sphincterotomy and endoscopic papillary balloon dilation have been recognized as first-line treatments for choledocholithiasis excluding difficult cases such(More)
