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 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)
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)
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)
BACKGROUND Pancreatodigestive tract anastomotic site stenosis is a problematic complication after pancreatoduodenectomy. OBJECTIVE We evaluated the feasibility and efficacy of endoscopic treatments for a stenotic pancreatodigestive tract anastomosis. DESIGN Retrospective study. SETTING Endoscopic units of a university-affiliated hospital and a general(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)
OBJECTIVES The aim of this study was to evaluate the usefulness of single-balloon enteroscopy (SBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with Billroth II gastrectomy (B-II) or Roux-en-Y anastomosis (R-Y). METHODS Thirteen SBE procedures were performed in 2 patients with B-II and 11 patients with R-Y at Tokyo Medical(More)
Endoscopic ultrasonography (EUS)-guided biliary drainage was performed for treatment of patients who have obstructive jaundice in cases of failed endoscopic retrograde cholangiopancreatography (ERCP). In the present study, we introduced the feasibility and outcome of EUS-guided choledochoduodenostomy in four patients who failed in ERCP. We performed the(More)
