Abstract Background Accurate preoperative assessment of the longitudinal extension of perihilar cholangiocarcinoma (PHCC) is essential for treatment planning. Mapping biopsies for PHCC remain challenging owing to technical difficulties and insufficient sample amounts. The aim of this study was to investigate the usefulness of a novel technique for mapping biopsies of PHCC. Methods Our novel method focused on a biliary stent delivery system for mapping biopsies. Fifty patients with PHCC undergoing endoscopic transpapillary mapping biopsy using the novel method were reviewed from August 2015 to June 2019. Results The median number of biopsy samples was six (range 1 – 17), and the rate of adequate sampling was 91.4 % (266 /291). Biopsy from the intrahepatic bile duct was possible in 82.0 % of patients (41 /50), and negative margins were confirmed in the resected specimens from 34 /39 patients who underwent surgery (87.2 %). None of the patients had post-endoscopic retrograde cholangiopancreatography pancreatitis. Conclusions With our novel method, accurate assessment of the longitudinal extension of PHCC might be expected with minimal trauma to the duodenal papilla.

Endoscopic ultrasonography (EUS) is a versatile tool that can be used to perform a variety of diagnostic and therapeutic procedures in the upper or lower gastrointestinal tract. The proximity of the echoendoscope to the pancreas, liver, and other thoracic and abdominal organs allows detailed examination or minimally invasive intervention that would not be feasible by surgical or percutaneous approaches. EUS is available with radial or linear scanning arrays and is capable of guiding fine-needle aspiration to acquire tissue for cytologic analysis. This review covers the role of EUS in chronic pancreatitis; pancreatic cysts; submucosal tumors; suspected choledocholithiasis; fecal incontinence; staging of malignancy in esophageal, pancreatic, gastric, and rectal cancer; celiac plexus block/neurolysis; fiducial placement; pseudocyst drainage and cystogastrostomy/cystoduodenostomy; endoscopic necrosectomy; and biliary drainage. Figures show peripancreatic cysts, gastrointestinal stromal tumor, common bile duct stone, esophageal adenocarcinoma, pancreatic head mass causing biliary obstruction and invading portal confluence, fine-needle aspiration of a pancreatic head mass, rectal adenocarcinoma, abdominal aorta with celiac artery and superior mesenteric artery, celiac plexus neurolysis, necrosectomy, and EUS-guided choledochoduodenostomy for failed endoscopic retrograde cholangiopancreatography. Tables list the Rosemont criteria for chronic pancreatitis and pancreatic cystic lesions.   Key words: bile duct stone, biliary drainage, echoendoscope, endoscopic ultrasonography, fine-needle aspiration, pancreatic cyst   This review contains 12 highly rendered figures, 2 tables, and 62 references.

Autoimmune pancreatitis (AIP) is characterized by enlargement of the pancreas and irregular narrowing of the main pancreatic duct. It is often associated with IgG4-related sclerosing cholangitis (IgG4-SC), in which the bile duct narrows. Although characteristic irregular narrowing of the pancreatic duct caused by endoscopic retrograde cholangiopancreatography is noted in AIP, it is difficult to differentiate between localized AIP and pancreatic carcinoma based on imaging of the pancreatic duct. While stenosis of the bile duct in IgG4-SC is characterized by longer-length stenosis than in cholangiocarcinoma, differentiation based on bile duct imaging alone is challenging. Endoscopic ultrasound (EUS) can characterize hypoechoic enlargement of the pancreas or bile duct wall thickening in AIP and IgG4-SC, and diagnosis using elastography and contrast-enhanced EUS are being evaluated. The utility of EUS-guided fine needle aspiration for the histological diagnosis of AIP has been reported and is expected to improve diagnostic performance for AIP. Findings in the bile duct wall from endoscopic retrograde cholangiopancreatography followed by intraductal ultrasonography are useful in differentiating IgG4-SC from cholangiocarcinoma. Diagnoses based on endoscopic ultrasonography play a central role in the diagnosis of AIP.
