BACKGROUND AND AIMS: Cholangiopancreatoscopy in evaluating pancreaticobiliary pathology is currently limited by suboptimal optics. The aim of this study was to characterize the operating characteristics of per-oral video cholangiopancreatoscopy with narrow-band imaging (POVCP) findings in indeterminate pancreaticobiliary disease and describe their association with neoplasia. METHODS: Data from consecutive patients undergoing POVCP for the evaluation of indeterminate pancreaticobiliary disease at a single tertiary care center were analyzed...

BACKGROUND AND AIMS: Digital cholangioscopes provide higher-resolution imaging of the pancreatobiliary tract compared with fiberoptic instruments. The role of a new, digital, single-operator cholangiopancreatoscopy (SOC) system for diagnosis and treatment of pancreatobiliary disorders in clinical practice is not known. METHODS: We performed a multicenter, observational study of 105 consecutive patients with suspected pancreatobiliary disorders. The main outcome measures were (1) sensitivity and specificity of SOC visual appearance and biopsies in the diagnosis of indeterminate biliary strictures and (2) achieving complete duct clearance in patients with biliary or pancreatic duct stones...

AIM: To assess the utility and safety of single-operator cholangiopancreatoscopy (SOCPS) using the SpyGlass system in widespread clinical application for biliary and pancreatic diseases. METHODS: This study was a prospective case series conducted in 20 referral centers in Japan. There were 148 patients who underwent SOCPS; 124 for biliary diseases and 24 for pancreatic diseases. The attempted interventions were SOCPS examination, SOCPS-directed tissue sampling, and therapy for stone removal, among others...

BACKGROUND: Recently, a new digital cholangiopancreatoscopy (DCPS) has been developed. The aim of this study is to retrospectively evaluate the utility of new DCPS in patients with pancreaticobiliary diseases. METHODS: Digital cholangiopancreatoscopy was used in 26 patients (16 men) with pancreaticobiliary diseases that could not be diagnosed and treated by standard endoscopic retrograde cholangiopancreatography (ERCP). The procedures included DCPS-guided tissue sampling and interventions...

A fifty-five year old female patient presented with jaundice, subfebrile fever and dark yellow urine since one month before admission. She lost weight 10 kilograms during one month. One day before admission to Ciptomangunkusumo General Hospital, she complained of worsened abdominal pain at right upper quadrant urging her to come to the emergency room. An abdominal examination revealed Murphy sign, mild hepatomegaly and deeply icteric sclera. Serum bilirubin was 21.8 mg/dl, alkaline phosphatase and gamma-glutamyltransferase levels were significantly elevated (1090 IU/L and 560 IU/L consecutively) while the transaminases were moderately high (ALT 80 U/L)...

AIM: Cholangiopancreatoscopy (CP) is an endoscopic technique that allows for direct visualization of the biliary and pancreatic ducts using a narrow caliber endoscope that passes through the working channel of a duodenoscope directly into the bile and/or pancreatic ducts. Little data is available on the safety of CP. We performed a multicenter retrospective study to evaluate the frequency and severity of adverse events with single operator CP. METHODS: A multicenter retrospective study was conducted...

AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy (POCPS). METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography (ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature review. RESULTS: Six consensus statements were generated: (1) POCPS is now an important additional tool during ERCP; (2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis; (3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail; (4) in patients with main duct intraductal papillary mucinous neoplasms (IPMN) POPS may be used to assess extent of tumor to assist surgical resection; (5) in difficult pancreatic ductal stones, POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and (6) additional indications for POCPS include selective guidewire placement, unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents...

BACKGROUND AND AIM: SpyGlass® cholangiopancreatoscopy system has shown early success in aiding diagnosis and management of pancreaticobiliary diseases. We aimed to assess the technical success, clinical success, diagnostic yield, therapeutic yield, and safety of the SpyGlass® system at a single institution. METHODS: A retrospective, single-center review of consecutive patients who underwent endoscopic retrograde cholangiopancreatography with SpyGlass® between January 2008 and August 2013 for a variety of indications...

Many surgeons prefer to perform endoscopic retrograde cholangiopancreatography (ERCP) before cholecystectomy, specifically in patients at significant risk of having biliary pathology. However, a preoperative diagnostic ERCP, without the use of an endoscopic ultrasound or magnetic retrograde cholangiopancreatoscopy, remains controversial. This is the result of the risk of either performing an unnecessary procedure and/or the development of post-ERCP pancreatitis (PEP). We performed a retrospective review of all surgeon-performed ERCPs at our institution between July 2011 and May 2013...

PURPOSE OF REVIEW: Endoscopists have long awaited advances in the equipment and techniques for cholangiopancreatoscopy. Since the turn of the millennium, endoscopists have witnessed an explosion in the development and refinement of the capabilities of cholangioscopes as they move from being almost exclusive to tertiary care academic settings to a wider range of practices. RECENT FINDINGS: Studies have tested and constructively critiqued the procedure, hoping to increase the success rate of diagnostic and therapeutic interventions...

BACKGROUND: Techniques to confirm suspected pancreaticobiliary (PB) malignancy when index sampling is non-diagnostic include cholangiopancreatoscopy (CP) and endoscopic ultrasound (EUS). However, comparative data are lacking. AIM: The purpose of this study was to compare the yield of EUS and CP for the diagnosis of PB pathology. METHODS: Consecutive patients with indeterminate PB pathology who underwent both CP and EUS within 3 months of each other were retrospectively identified...

BACKGROUND AND AIM: A single-operator cholangiopancreatoscopy was developed to overcome a problem in conventional peroral cholangiopancreatoscopy. The aim of this pilot study was to clarify the clinical utility of single-operator cholangiopancreatoscopy using a SpyGlass probe through an endoscopic retrograde cholangiopancreatography (ERCP) catheter. METHODS: Patients undergoing ERCP with a SpyGlass probe passed through a catheter were included in this study. The SpyGlass probe was inserted into the catheter following successful cannulation, and cholangiopancreatoscopy was performed by a single operator...

BACKGROUND & AIMS: It is a challenge to collect samples from bile duct strictures to diagnose patients with cholangiocarcinoma. We investigated the utility of the Spyglass Spyscope, a single-operator endoscope that is used to perform cholangiopancreatoscopy, to identify extrahepatic cholangiocarcinoma in patients who were not diagnosed with this disorder by endoscopic retrograde cholangiopancreatography (ERCP) cytology or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) analyses...

Shahzad Iqbal, Peter D Stevens
Establishing a tissue diagnosis in patients with suspected pancreaticobiliary malignancies remains challenging. Endoscopic retrograde cholangiopancreatography (ERCP)-based sampling methods have been reviewed in a previous issue of this journal but, unfortunately, the diagnostic yield continues to be inadequate in a significant minority of patients. The availability and image quality of cholangioscopy and pancreatoscopy have advanced in the last few years and our ability to make a diagnosis on imaging alone is improving...
