Abstract
The growing and evolving field of EUS and advanced hepatobiliary endoscopy has amplified traditional upper gastrointestinal endoscopy and unveiled novel options for remaining unsolved hepatobiliary issues, both diagnostically and therapeutically. This conceptually appealing and fascinating integration of endoscopy within the practice of hepatology is referred to as 'endo-hepatology'. Endo-hepatology focuses on the one hand on disorders of the liver parenchyma and liver vasculature and of the hepatobiliary tract on the other hand. Applications hanging under the umbrella of endohepatology involve amongst others EUS-guided liver biopsy, EUS-guided portal pressure measurement, EUS-guided portal venous blood sampling, EUS-guided coil & glue embolization of gastric varices and spontaneous portosystemic shunts as well as ERCP in the challenging context of (decompensated cirrhosis) and intraductal cholangioscopy for primary sclerosing cholangitis. Although endoscopic proficiency however does not necessarily equal in an actual straightforward end-solution for currently persisting (complex) hepatobiliary situations. Therefore, endohepatology continues to generate high-quality data to validate and standardize procedures against currently considered (best available) "golden standards" while continuing to search and trying to provide novel minimally invasive solutions for persisting hepatological stalemate situations. In the current review, we aim to critically appraise the status and potential future directions of endo-hepatology.

Direct Single-Operator Cholangioscopy and Intraductal Ultrasonography in Patients with Indeterminate Biliary Strictures: A Single Center Experience. Diagnostics (Basel) 2024; 14:1316. [PMID: 39001208 PMCID: PMC11240807 DOI: 10.3390/diagnostics14131316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 06/16/2024] [Accepted: 06/18/2024] [Indexed: 07/16/2024] Open
Abstract
The evaluation of biliary strictures poses a challenge due to the low sensitivity of standard diagnostic approaches, but the advent of direct single-operator cholangioscopy (DSOC) has revolutionized this paradigm. Our study aimed to assess the diagnostic performance of DSOC and DSOC-targeted biopsies, intraductal ultrasound (IDUS), and standard brush cytology in patients with indeterminate biliary strictures (IBS). We reviewed patients who underwent advanced diagnostic evaluation for IBS at our endoscopy unit from January 2018 to December 2022, all of whom had previously undergone at least one endoscopic attempt to characterize the biliary stricture. Final diagnoses were established based on surgical pathology and/or clinical and radiological follow-up spanning at least 12 months. A total of 57 patients, with a mean age of 67.2 ± 10.0 years, were included, with a mean follow-up of 18.2 ± 18.1 months. The majority of IBS were located in the distal common bile duct (45.6%), with malignancy confirmed in 35 patients (61.4%). DSOC and IDUS demonstrated significantly higher accuracies (89.5% and 82.7%, respectively) compared to standard cytology (61.5%, p < 0.05). Both DSOC visualization and IDUS exhibited optimal diagnostic yields in differentiating IBS with an acceptable safety profile.

Abstract
Background Conventional peroral methods to visualize biliary strictures are not feasible in some patients with altered anatomy or biliary obstruction, and percutaneous transhepatic cholangioscopy can be used as an alternative procedure. This study aimed to retrospectively review the use of percutaneous transhepatic cholangiography using the SpyGlass DS technology (S-PTCS) during a 5-year period at a Danish tertiary referral centre. Materials and methods All patients who underwent S-PTCS at a single Danish tertiary referral centre between 2016 and 2021 were retrospectively analyzed. The visual, technical, and overall success rates of S-PTCS were analyzed, as well as the complication rate. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of S-PTCS were calculated. Results Twenty-two patients were included in the study. Visual, technical, and overall success of S-PTCS was achieved in 17/22, 22/22, and 21/22 patients, respectively. S-PTCS yielded a sensitivity of 83.3%, a specificity of 100%, a PPV of 100%, a NPV of 94.1%, and an accuracy of 95.4%. Complications occurred in 1/22 patients. Conclusion S-PTCS is a safe modality, with high success rates, high predictive values, and a low rate of complications. This study suggests that S-PTCS is an alternative to conventional methods in patients with indeterminate biliary strictures where conventional methods were unfeasible.

Abstract
Surgical clip migration into the common bile duct (CBD) with subsequent stone formation is an exceedingly rare complication following both laparoscopic and open cholecystectomy, with fewer than 100 cases reported in the literature. Herein, we present the case of a 78-year-old female who presented with abdominal pain and dark urine six years after an open cholecystectomy. Her abdominal ultrasonography revealed no abnormalities, with only mild derangements noted in liver function tests. However, computed tomography of the abdomen unveiled a single metallic surgical clip lodged within the CBD, surrounded by a bile stone, alongside another clip at the gallbladder fossa. The patient underwent endoscopic retrograde cholangiopancreatography (ERCP), during which the clip was successfully removed. The procedure has utilized SpyGlass cholangioscopy. While clip migration into the CBD remains a rare phenomenon, it should be considered in the differential diagnosis of patients presenting with obstructive jaundice or biliary colic post-cholecystectomy. Minimally invasive management by ERCP is the procedure of choice for migrated clips-related complications but surgical common bile duct exploration may be necessary. This case highlights the importance of vigilance and prompt intervention in managing post-cholecystectomy clip migration (PCCM) but potentially serious postoperative complications.

Abstract
BACKGROUND Direct bile ducts visualization through cholangioscopy has gained popularity due to its better diagnostic accuracy than a standard ERCP in indeterminate biliary stricture. METHODS We aimed to review our catheter-based cholangioscopy interventions in patients with indeterminate biliary stenosis, using the SpyGlass Direct Visualization System (SDVS) and summarize our experience in terms of procedures and results. We collected 25 consecutive patients with indeterminate biliary stricture over 3 years. RESULTS The overall procedural success in our cohort amounted to 96% (24/25). If we focus on the diagnostic procedures, the ability to merely visualize the region of interest/lesion and perform biopsy of the lesion was possible in 96% (24/25) In our cohort localization in the common bile duct (P=0.03; 95% CI: 0.27-0.96) was found as positive determining factor for diagnosis. Sensitivity, specificity and accuracy for visual diagnosis by SDVS in our cohort were 100, 83.3 and 96%, respectively. The use of biopsy or obtaining a histological diagnosis to assist in identifying patients with malignant stenosis, to exclude malignancy and to correctly classify diagnosed patients resulted in a sensitivity of 100%, a specificity of 73% with an overall accuracy of 94.4%. Only a mild adverse event (cholangitis, treated conservatively) occurred. CONCLUSIONS Today, the SDVS should be considered essential in diagnosing indeterminate biliary strictures, since the procedure is associated with high procedural success in terms of diagnostic accuracy, alters clinical outcome in over 80% of considered insolvable cases, with an acceptable safety profile.

Abstract
BACKGROUND Duodenoscope-related multidrug-resistant organism (MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography (ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. METHODS This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score (1 to 10) on performance rating of the single-use duodenoscope, and adverse event (AE) rate. RESULTS A total of 66 patients (26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47 (71.2%) grade 3 and 19 (28.8%) grade 4. The technical success rate was 98.5% (65/66). Procedural duration was 64 (interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66 (1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients (6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis (PEP), 1 cholangitis and 1 bleeding. CONCLUSIONS Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

Abstract
Background To determine the superiority of the combination of endoscopic retrograde cholangiopancreatography (ERCP) and digital single-operator cholangioscopy (DSOC) in the same sitting over the individual modality alone in patients with indeterminate biliary strictures. Materials and Methods A randomized study enrolled 60 adult patients with biliary strictures who were randomized into two groups: ERCP + DSOC and ERCP/DSOC. Histopathologic or cytologic assessment was performed in terms of benign, indeterminate, or malignant nature of the strictures. Procedural adverse events were documented. Accuracy in terms of sensitivity (Sn), specificity (Sp), and predictive value [positive (PPV) and negative (NPV)] were noted. Results As per final diagnosis, in ERCP/DSOC group, there were 12 (40%) benign cases and 18 (60%) malignant cases, and in group ERCP + DSOC, there were 8 (26.67%) benign cases and 22 (73.33%) malignant cases. ERCP/DSOC labeled 16 (53.33%) patients as benign, 8 (26.67%) as malignant, and 6 (20%) as indeterminate, while ERCP + DSOC labeled 8 (26.67%) as benign, 17 (56.67%) as malignant, and 5 (16.67%) as indeterminate. The Sn, Sp, PPV, and NPV of ERCP/DSOC were 44.4%, 75%, 100%, and 56.25%, and for ERCP + DSOC was 77.27%, 62.50%, 100%, and 62.5%, respectively (P = 0.033). Side effects were statistically similar in both the groups (P > 0.05). Conclusion To conclude, the combination of ERCP with DSOC is safe and effective with higher diagnostic sensitivity (77.27%) in comparison to standard ERCP or DSOC alone (44.4%) for the diagnosis of biliary strictures.

Abstract
Gastrointestinal endoscopy has long been a reliable backbone in the diagnosis and management of hepatobilary disorders and their complications. However, with evolving non-invasive testing, personalised medicine has reframed the utility and necessity of endoscopic screening. Conversely, the growing interest and use of endoscopic ultrasound (EUS) and advanced endoscopy within gastrointestinal units has also opened novel diagnostic and therapeutic avenues for patients with various hepatobiliary diseases. The integration of "advanced endoscopy" within the practice of hepatology is nowadays referred to as "endo-hepatology". In essence, endo-hepatology consists of two pillars: one focusing primarily on disorders of the liver parenchyma, vascular disorders, and portal hypertension, which is mainly captured via EUS, while the other targets the hepatobiliary tract via endoscopic retrograde cholangiopancreatography and advanced imaging. Applications under the umbrella of endo-hepatology include, amongst others, EUS-guided liver biopsy, EUS-guided portal pressure gradient measurement, coil and glue embolisation of gastric varices as well as cholangioscopy. As such endo-hepatology could become an attractive concept wherein advanced endoscopy might reinforce the medical management of patients with hepatobiliary disorders and their complications after initial basic work-up. In this review, we discuss current trends and future developments within endo-hepatology and the remaining hurdles to overcome.

Abstract
BACKGROUND Mirizzi syndrome is an uncommon clinical complication for which the available treatment options mainly include open surgery, laparoscopic surgery, endoscopic retrograde cholangiopancreatography (ERCP), electrohydraulic lithotripsy, and laser lithotripsy. Here, a patient diagnosed with type I Mirizzi syndrome was treated with electrohydraulic lithotripsy under SpyGlass direct visualization, which may provide a reference to explore new treatments for Mirizzi syndrome. CASE SUMMARY This paper describes a middle-aged female patient with suspected choledocholithiasis who complained for over 1 mo of intermittent abdominal pain, dark yellow urine, jaundice, and was proposed to undergo ERCP lithotomy. Mirizzi syndrome was found during the operation and confirmed by SpyGlass. Electrohydraulic lithotripsy was performed under the direct vision of SpyGlass. After the lithotripsy, the stones were extracted using the stone extraction basket and balloon. After the operation, the patient developed transient hyperamylasemia. Through a series of symptomatic treatments (such as fasting, fluids and anti-inflammation medications), the symptoms of the patient improved. Finally, laparoscopic cholecystectomy or open cholecystectomy was performed after a half-year post-operatively. CONCLUSION Direct visualization-guided laser or electrohydraulic lithotripsy with SpyGlass is feasible and minimally invasive for type I Mirizzi syndrome without apparent unsafe outcomes.

ACG Case Rep J 2023; 10:e01095. [PMID: 37434659 PMCID: PMC10332834 DOI: 10.14309/crj.0000000000001095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 06/05/2023] [Indexed: 07/13/2023] Open
Abstract
When evaluating biliary strictures, establishing a diagnosis can present challenges. The first-line approach of endoscopic retrograde cholangiopancreatography can often involve anatomic restrictions. Traditionally, percutaneous transhepatic cholangioscopy has been the answer for biopsies unable to be obtained with the modalities above but requires time for large tract dilation and days of sinus tract maturation to allow for a scope. We present a novel case of percutaneous digital cholangioscopy with SpyGlass DS, a small caliber scope traditionally used with endoscopic retrograde cholangiopancreatography, used for percutaneous transhepatic cholangioscopy after previous failed attempts by several different standard methods. Our case highlights a multidisciplinary approach in ultimately diagnosing malignancy.

J Clin Med 2022; 11:6425. [PMID: 36362652 PMCID: PMC9654474 DOI: 10.3390/jcm11216425] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/13/2022] [Accepted: 10/28/2022] [Indexed: 06/03/2024] Open
Abstract
Peroral cholangioscopy (POCS) is believed to be effective in treating intrahepatic stones; however, reports on its efficacy are few. We reviewed the results of intrahepatic stones treated with fluoroscopic guidance or POCS. This study included 26 patients who underwent endoscopic treatment for intrahepatic stones at our institution between January 2017 and December 2021. We retrospectively evaluated the procedure time and adverse events in the first session and the rate of complete stone removal. Complete stone removal was achieved in 92% (24/26); POCS was required in 16 of 26 (62%) procedures and the complete stone removal was achieved in 15 of 16 (94%) of these procedures. The POCS group had a significantly longer procedure time than the fluoroscopy group. Cholangitis incidence was high; however, no difference was noted between patients with and without POCS, and all cases were mild and treated conservatively. Endoscopic treatment for intrahepatic stones may lead to an increase in the incidence of cholangitis, requires specialized devices such as a cholangioscope, and should be performed in an established institution by experienced staff. POCS is useful for intrahepatic stones formed upstream of the stenosis and intrahepatic stones piled in the bile duct.

Abstract
BACKGROUND AND AIM Digital single-operator cholangioscopy (D-SOC) is an endoscopic procedure that is increasingly used for the management of bilio-pancreatic diseases. We aimed to investigate the efficacy and safety of D-SOC for diagnostic and therapeutic indications. METHODS This is a multicenter, prospective study(January 2016-June 2019) across eighteen tertiary centers. The primary outcome was procedural success of D-SOC. Secondary outcomes were: D-SOC visual assessment and diagnostic yield of SpyBite biopsy in cases of biliary strictures, stone clearance rate in cases of difficult biliary stones, rate of adverse events(AEs) for all indications. RESULTS D-SOC was performed in 369 patients (201(54,5%) diagnostic and 168(45,5%)therapeutic). Overall, procedural success rate was achieved in 360(97,6%) patients. The sensitivity, specificity, PPV, NPV and accuracy in biliary strictures were: 88,5%, 77,3%, 83,3%, 84,1% and 83,6% for D-SOC visual impression; 80,2%, 92,6%, 95,1%, 72,5% and 84,7% for the SpyBite biopsy, respectively. For difficult biliary stones, complete duct clearance was obtained in 92,1% patients (82,1% in a single session). Overall, AEs occurred in 37(10%) cases.The grade of AEs was mild or moderate for all cases, except one which was fatal. CONCLUSION D-SOC is effective for diagnostic and therapeutic indications.Most of the AEs were minor and managed conservatively, even though a fatal event has happened that is not negligible and should be considered before using D-SOC.

Abstract
BACKGROUND Peroral cholangioscopy (POC)-guided lithotripsy is an effective treatment for difficult biliary stones. A clear definition of factors associated with the efficacy of POC-guided lithotripsy in one session and the performance of electrohydraulic lithotripsy (EHL) and laser lithotripsy (LL) have not clearly emerged. METHODS This was a non-randomized prospective multicenter study of all consecutive patients who underwent POC lithotripsy (using EHL and/or LL) for difficult biliary stones. The primary endpoint of the study was the number of sessions needed to achieve complete ductal clearance and the factors associated with this outcome. Secondary endpoints included the evaluated efficacies of LL and EHL. RESULTS Ninety-four patients underwent 113 procedures of EHL or LL. Complete ductal clearance was obtained in 93/94 patients (98.94%). In total, 80/94 patients (85.11%) achieved stone clearance in a single session. In the multivariate analysis, stone size was independently associated with the need for multiple sessions to achieve complete ductal clearance (odds ratio = 1.146, 95% confidence interval: 1.055-1.244; p = 0.001). Using ROC curves and the Youden index, 22 mm was found to be the optimal cutoff for stone size (95% confidence interval: 15.71-28.28; p < 0.001). The majority of the patients (62.8%) underwent LL in the first session. Six patients failed the first session with EHL after using two probes and therefore were crossed over to LL, obtaining ductal clearance in a single additional session with a single LL fiber. EHL was significantly associated with a larger number of probes (2.0 vs. 1.02) to achieve ductal clearance (p < 0.01). The mean procedural time was significantly longer for EHL than for LL [72.1 (SD 16.3 min) versus 51.1 (SD 10.5 min)] (p < 0.01). CONCLUSIONS POC is highly effective for difficult biliary stones. Most patients achieved complete ductal clearance in one session, which was significantly more likely for stones < 22 mm. EHL was significantly associated with the need for more probes and a longer procedural time to achieve ductal clearance.

Peroral Cholangioscopy-Guided Targeted Biopsy versus Conventional Endoscopic Transpapillary Forceps Biopsy for Biliary Stricture with Suspected Bile Duct Cancer. J Clin Med 2022; 11:jcm11020289.

Abstract
Background: The recent improvement of peroral cholangioscopy (POCS) maneuverability has enabled the precise, targeted biopsy of bile duct lesions under direct cholangioscopic vision. However, as only small-cup biopsy forceps can pass through the scope channel, the resulting small sample size may limit the pathological diagnosis of biopsy specimens. This study compared the diagnostic abilities of POCS-guided biopsy and conventional fluoroscopy-guided biopsy for bile duct cancer. Method: This multicenter, retrospective cohort study included patients exhibiting bile duct stricture with suspected cholangiocarcinoma in whom POCS-guided and fluoroscopy-guided biopsies were performed in the same session. The primary endpoint was the diagnostic sensitivity for malignancy. The size and quality of the biopsy specimens were also compared. Result: A total of 59 patients were enrolled. The sensitivity of POCS-guided biopsy was similar to that of fluoroscopy-guided biopsy (54.0% and 64.0%, respectively). However, when the modalities were combined, the sensitivity increased to 80.0%. The mean specimen size from POCS-guided biopsy was significantly smaller than that from fluoroscopy-guided biopsy. The specimen quality using fluoroscopy-guided biopsy was also better than that using POCS-guided biopsy. Conclusions: The diagnostic sensitivity of POCS-guided biopsy is still insufficient, mainly because of the limited specimen quantity and quality. Therefore, conventional fluoroscopy-guided biopsy would be helpful to improve diagnostic sensitivity.

Abstract
Post-cholecystectomy clip migration with formation of bile duct stones is a known but rare complication of laparoscopic cholecystectomy. This report discusses the case of a 64-year-old lady who presented with biliary colic symptoms 12 years post laparoscopic cholecystectomy. Computed tomography of the abdomen demonstrated one surgical clip located in the distal common bile duct, with a bile stone formed around it. This was removed via ERCP with spyglass cholangioscopy and lithotripsy.

Abstract
The endoscopic diagnosis of biliary tract lesions is applied as a non-invasive method; however, its diagnostic accuracy is not yet high. Moreover, digital cholangioscopy is used for directly visualizing the inside of the bile duct, resulting in a more precise biopsy. We present the case series of the outcomes of diagnosis using digital cholangioscopy in patients who underwent cholangioscopy for the evaluation of biliary stenosis in our department between January 2014 and March 2021. The controls were those who underwent a biopsy for biliary stenosis with conventional endoscopic retrograde cholangiopancreatography (ERCP). Background data for each case were collected, and the clinical outcomes by biopsy were evaluated, focusing on the accuracy of the diagnosis. Cholangioscopy was performed in 15 cases, while a conventional biopsy by ERCP was performed in 172 cases. Nine of 15 cases (60.0%) were diagnosed with cholangiocarcinoma. The number of specimens obtained through conventional ERCP and cholangioscopy was 2.5 ± 1.3 and 3.3 ± 1.5, respectively (p = 0.043). The diagnostic accuracy of conventional ERCP and cholangioscopy were 65.7% (113 of 172 cases) and 100%, respectively, which was significantly higher in the group with cholangioscopy. Digital cholangioscopy is useful when the diagnosis of the biliary stricture using the conventional ERCP method is difficult.

Abstract
BACKGROUND AND AIMS Digital single-operator cholangioscopy (d-SOC) with cholangioscopic biopsy sampling has shown promise in the evaluation of indeterminate biliary strictures. Some studies have suggested higher sensitivity for visual impression compared with biopsy sampling, although assessors were not blinded to previous investigations. We aimed to investigate the diagnostic accuracy and interobserver agreement (IOA) of d-SOC in the visual appraisal of biliary strictures when blinded to additional information. METHODS A multicenter, international cohort study was performed. Cholangioscopic videos in patients with a known final diagnosis were systematically scored. Pseudonymized videos were reviewed by 19 experts in 2 steps: blinded for patient history and investigations and unblinded. RESULTS Forty-four high-quality videos were reviewed of 19 benign and 25 malignant strictures. The sensitivity and specificity for the diagnosis of malignancy was 74.2% and 46.9% (blinded) and 72.7% and 62.5% (unblinded). Cholangioscopic certainty of a malignant diagnosis led to overdiagnosis (sensitivity, 90.6%; specificity, 33%), especially if no additional information was provided. The IOA for the presence of malignancy was fair for both assessments (Fleiss' κ = .245 [blinded] and κ = .321 [unblended]). For individual visual features, the IOA ranged from slight to moderate for both assessments (κ = .059-.400 vs κ = .031-.452). CONCLUSIONS This study showed low sensitivity and specificity for blinded and unblinded d-SOC video appraisal of indeterminate biliary strictures, with considerable interobserver variation. Although reaching a consensus on the optical features of biliary strictures remains important, optimizing visually directed biopsy sampling may be the most important role of cholangioscopy in biliary stricture assessment.

Abstract
BACKGROUND/AIMS Digital single-operator cholangioscopy (dSOC) has revolutionized bile duct visualization. Interventions like electrohydraulic or laser lithotripsy, inspection of suspicious areas, and targeted biopsies have become possible quick and easy. One main indication for dSOC remains the evaluation of indeterminate biliary strictures. OBJECTIVE AND METHODS We analyzed 180 consecutive dSOCs procedures performed in a high-volume tertiary center to evaluate sensitivity, specificity as well as positive and negative predictive values (PPV and NPV) for indeterminate strictures. Furthermore, technical success and complications were analyzed. RESULTS In 92-97%, the region of interest was reached and successfully visualized. In 83-100%, targeted biopsies were obtained from the suspicious area. Only the distal bile duct was less successful with only 84 and 62%, respectively. In general, dSOC procedures were safe. Cholangitis was the main complication. Regarding the diagnostic accuracy of dSOC of indeterminate biliary strictures, we found a sensitivity of 0.87 and specificity of 0.88, over all. Within the whole cohort, the investigators' assessment directly after dSOC had a PPV of 0.63 and a NPV of 0.97. In patients with biliary lesions or stenosis suspicious for malignancy, the dSOC-based visual diagnosis revealed a very high diagnostic accuracy with sensitivity and specificity of 1.0 (95% CI 0.86-1.0) and 0.76 (95% CI 0.56-0.9) with a PPV of 0.77 (95% CI 0.59-0.9) and a high NPV of 1.0 (95% CI 0.85-1.0). CONCLUSIONS Our study demonstrates that dSOC has a high diagnostic accuracy as well as a favorable safety profile. Therefore, dSOC should be discussed as standard of care during endoscopic retrograde cholangiography for indeterminate biliary lesions.

Alrajhi S, Barkun A, Adam V, Callichurn K, Martel M, Brewer O, Khashab MA, Forbes N, Almadi MA, Chen YI. Early cholangioscopy-assisted electrohydraulic lithotripsy in difficult biliary stones is cost-effective. Therap Adv Gastroenterol 2021; 14:17562848211031388. [PMID: 34804204 PMCID: PMC8600178 DOI: 10.1177/17562848211031388] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 06/22/2021] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND AND AIMS Single-operator cholangioscopy-assisted electrohydraulic lithotripsy (SOC-EHL) is effective and safe in difficult choledocholithiasis. The optimal timing of SOC-EHL use, however, in refractory stones has not been elucidated. The following aims to determine the most cost-effective timing of SOC-EHL introduction in the management of choledocholithiasis. METHODS A cost-effectiveness model was developed assessing three strategies with a progressively delayed introduction of SOC-EHL. Probability estimates of patient pathways were obtained from a systematic review. The unit of effectiveness is complete ductal clearance without need for surgery. Cost is expressed in 2018 US dollars and stem from outpatient US databases. RESULTS The three strategies achieved comparable ductal clearance rates ranging from 97.3% to 99.7%. The least expensive strategy is to perform SOC-EHL during the first endoscopic retrograde cholangiography pancreatography (ERCP) (SOC-1: 18,506$). The strategy of postponing the use of SOC-EHL to the third ERCP (SOC-3) is more expensive (US$18,895) but is 2% more effective. (0.9967). SOC-EHL during the second ERCP in the model (SOC-2) is the least cost-effective. Sensitivity analyses show altered conclusions according to the cost of SOC-EHL, effectiveness of conventional ERCP, and altered willingness-to-pay (WTP) thresholds with early SOC-1 being the most optimal approach below a WTP cut-off of US$20,295. CONCLUSIONS Early utilization of SOC-EHL (SOC-1) in difficult choledocholithiasis may be the least costly strategy with an effectiveness approximating those achieved with a delayed approach where one or more conventional ERCP(s) are reattempted prior to SOC-EHL introduction.

Abstract
BACKGROUND Diagnosis of malignant biliary obstruction is complicated and lacks accuracy. Exosomes may be secreted by malignant tumors; intact miRNAs from exosomes might serve as potential biomarkers for the disease. AIM To identify exosomal microRNAs in human bile among benign and malignant biliary obstructions. METHODS Bile samples were collected from patients undergoing therapeutic endoscopic retrograde cholangiopancreatography for biliary obstruction. Exosome microRNAs were determined by RNA-sequencing in the discovery cohort, which comprising benign (n = 5) cases and malignant biliary obstruction (n = 5) cases. Then, the diagnostic performance of the two up-regulated microRNAs (mir-483-5p and mir-126-3p) of bile exosomes was verified by analysis of 82 patients with a diagnosis of malignant (n=37) or nonmalignant (n=45) biliary obstruction. RESULTS In both cohorts, the expressions of mir-483-5p and mir-126-3p were significantly higher in bile exosomes samples from patients with malignant biliary obstructions than controls. In the verification cohort, the two miRNAs can distinguished the benign and malignant groups with high diagnostic accuracy and specificity; the diagnostic values of the two microRNAs were better than serum carbohydrate antigen 19-9 (CA19-9), area under the curve (AUC) were 0.81 and 0.74. CONCLUSION The expression of exosomal mir-483-5p and mir-126-3p in the bile samples discriminates between patients with malignant and nonmalignant biliary obstructions.

Abstract
Patients with cholangiocarcinoma have poor survival since the majority of patients are diagnosed at a stage precluding surgical resection, due to locally irresectable tumors and/or metastases. Optimization of diagnostic strategies, with a principal role for tissue diagnosis, is essential to detect cancers at an earlier stage amenable to curative treatment. Current barriers for a tissue diagnosis include both insufficient tissue sampling and a difficult cyto- or histopathological assessment. During endoscopic retrograde cholangiopancreatography, optimal brush sampling includes obtaining more than one brush within an individual patient to increase its diagnostic value. Currently, no significant increase of the diagnostic accuracy for the new cytology brush devices aiming to enhance the cellularity of brushings versus standard biliary brush devices has been demonstrated. Peroral cholangioscopy with bile duct biopsies appears to be a valuable tool in the diagnostic work-up of indeterminate biliary strictures, and may overcome current technical difficulties of fluoroscopic-guided biopsies. Over the past years, molecular techniques to detect chromosomal instability, mutations and methylation profiling of tumors have revolutionized, and implementation of these techniques on biliary tissue during diagnostic work-up of biliary strictures may be awaited in the near future. Fluorescence in situ hybridization has already been implemented in routine diagnostic evaluation of biliary strictures in several centers. Next-generation sequencing is promising for standard diagnostic care in biliary strictures, and recent studies have shown adequate detection of prevalent genomic alterations in KRAS, TP53, CDKN2A, SMAD4, PIK3CA, and GNAS on biliary brush material. Detection of DNA methylation of tumor suppressor genes and microRNAs may evolve over the coming years to a valuable diagnostic tool for cholangiocarcinoma. This review summarizes optimal strategies for biliary tissue sampling during endoscopic retrograde cholangiopancreatography and focuses on the evolving molecular techniques on biliary tissue to improve the differentiation of benign and malignant biliary strictures.

Abstract
BACKGROUND AND AIMS Various macroscopic features are proposed for the diagnosis of biliary lesions during digital single-operator cholangioscopy (DSOC); however, neovasculature may be one of the most reliable features of neoplasia. We aimed to evaluate the detection of neovasculature during DSOC to distinguish neoplastic from non-neoplastic bile duct lesions. METHODS A retrospective, single-center, cohort study was used. Neovasculature was defined as the presence of irregular or "spider" vascularity on bile duct lesions. The accuracy of detection of neovasculature for the identification of neoplastic lesions was estimated using the histologic results, surgical specimens, and/or 6-month follow-up as the criterion standard. Interobserver agreement analysis (kappa value) was performed between 2 expert endoscopists and 3 nonexpert physicians. RESULTS Ninety-five patients were included; the median age was 65.6 years (range, 20-93 years), and 51 (53.7%) patients were female. Signs of neovasculature were observed in 65 of 95 (68.4%) patients. Histology confirmed neoplasia in 48 of 95 (50.5%) patients, and 6-month follow-up survival confirmed neoplasia in 52 of 95 (54.7%) patients. The use of vascularity for identifying neoplastic lesions achieved an accuracy of 80%, sensitivity of 94%, specificity of 63%, positive predictive value of 75%, negative predictive value of 90%, positive likelihood ratio of 2.53 (95% confidence interval, 1.71-3.76), and negative likelihood ratio of 0.09 (95% confidence interval, 0.03-0.28). The interobserver and intraobserver agreement were excellent (κ > 80%; P < .001) between expert endoscopists and nonexpert physicians. CONCLUSION Detection of irregular or spider vascularity on bile duct lesions during DSOC evaluations accurately identifies biliary neoplastic lesions. Prospective multicenter trials are required to evaluate neovasculature as a single factor for predicting neoplasia.

ARQUIVOS DE GASTROENTEROLOGIA 2021; 57:347-353.

Abstract
BACKGROUND Biliary complications remain one of the most important causes of morbidity and graft loss after liver transplant (LT). Endoscopic therapy of biliary complications has proven to be effective over time, leaving surgical treatment restricted to only very few cases. However, we cannot yet predict which patients will have the greatest potential to benefit from endoscopic treatment. OBJECTIVE On this premise we decide to conduct this study to evaluate the role and safety of single operator cholangioscopy (SOC) in the endoscopic treatment of post-LT biliary anastomotic strictures (AS). METHODS Between March/2016 and June/2017, 20 consecutive patients referred for endoscopic treatment for biliary anastomotic stricture were included in this prospective observational cohort study. Inclusion criteria were age over 18 years old, and a deceased LT performed within at least 30 days. Exclusion criteria were non-anastomotic biliary stricture, biliary leakage, cast syndrome, any previous endoscopic therapy, pregnancy and inability to provide informed consent. All patients underwent SOC before endoscopic therapy with fully covered self-expandable metal stent (FCSEMS) and after stent removal. RESULTS At pre-treatment SOC, stricture orifice and fibrotic changes could be visualized in all patients, vascular changes and surgical sutures in 60% and acute inflammatory changes in 30%. SOC was essential for guidewire placement in five cases. FCSEMS was successfully deployed in all patients. Stricture resolution rate was 44.4% (median stent indwelling 372 days). Stricture recurrence was 12.5% (median follow-up of 543 days). Adverse events were distal (66.6%) and proximal (5.5%) stent migration, stent occlusion (16.6%), severe abdominal pain (10%) and mild acute pancreatitis (10%). SOC was repeated after FCSEMS removal. Post-treatment SOC showed fibrotic changes in all but one patient; vascular and acute inflammatory changes were less frequent in comparison to index procedure. The disappearance of suture material was remarkable. None of the cholangioscopic findings were statistically correlated to treatment outcome or stricture recurrence. CONCLUSION Endoscopic retrograde cholangiography with SOC is feasible in post-LT patients with AS. Cholangioscopic findings can be classified into fibrotic, vascular and acute inflammatory changes. Cholangioscopy may be helpful to assist guidewire passage, but Its overall role for changing management is post-LT patients was not demonstrated.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is the second most frequent primary liver tumor and defined as the heterogeneous group of tumors derived from cells in the biliary tree. METHODS AND RESULTS Based on the anatomical locations (intrahepatic, perihilar, and distal), there are various approaches to the diagnosis and treatment of CCA. Imaging modalities, staging classifications, understandings around natural behavior of CCA, and therapeutic strategies have had remarkable progress in recent years. CONCLUSIONS This article reviews and discusses the epidemiology, clinical presentation, diagnosis, and treatment modalities of CCA; determines the appropriate inclusion and exclusion criteria for liver transplantation (LT); and defines the risk of disease progression for patients in the waiting list of LT.

Abstract
BACKGROUND AND AIMS Identifying malignant biliary strictures using endobiliary brushing cytology specimens is important for treatment decision-making and prognosis prediction. The sensitivity of brushing cytology specimens based on Papanicolaou (Pap) staining is low, which hampers accurate diagnosis of indeterminate strictures. Here, we assessed the diagnostic value of immunohistochemical (IHC) and immunofluorescence (IF) staining for methionyl-tRNA synthetase 1 (MARS1). METHODS Endobiliary brushing cytology specimens were obtained during ERCP from 80 patients with an extrahepatic biliary stricture. Pap and MARS1 IF staining were performed on liquid-based cytology slides derived from these specimens. Sections of bile duct adenocarcinoma and normal bile duct tissue were obtained from 45 patients who underwent surgery for malignant biliary stricture, and MARS1 levels were evaluated by IHC staining. RESULTS MARS1 IF staining was applied to brushing cytology specimens, and the results showed strong signals in malignant biliary structures but not in the negative for malignancy specimens. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 70.4%, 96.2%, 97.4%, 56.8%, and 78.8%, respectively, for conventional Pap staining and 98.1%, 96.1%, 98.1%, 96.2%, and 97.5%, respectively, for MARS1 IF (P < .0001). When IHC staining was used, MARS1 was detected in 45 bile duct adenocarcinoma sections but not in 15 normal bile duct sections. Moreover, MARS1 mRNA and protein levels were significantly higher in bile duct adenocarcinoma sections according to polymerase chain reaction and Western blot, respectively. CONCLUSIONS The high sensitivity and accuracy of MARS1 IF staining enabled detection of malignancy in patients with indeterminate biliary stricture. Further prospective studies are needed to validate our findings. (Clinical trial registration number: KCT 0003285.).

Abstract
INTRODUCTION Endoscopic removal of common bile duct stones has a high success rate ranging from 85% to 95%. Bile duct stones >15 mm are difficult and frequently require lithotripsy. Peroral cholangioscopy (POC) allows lithotripsy with similar success rates. AIM To determine the efficacy and safety of cholangioscopy-guided lithotripsy used in the treatment of difficult to remove bile duct stones vs. conventional therapy. METHODS Search was based in Medline, Embase, Cochrane Central, Lilacs/Bireme. Studies enrolling patients referred for the removal of difficult bile duct stones via POC were considered eligible. Two analyses were carried out separately, one included randomized controlled trials (RCTs) and another observational studies. RESULTS Forty-six studies were selected (3 RTC and 43 observational). In the analysis there was no statistical significant difference between successful endoscopic clearance (RD=-0.02 CI: -0.17, 0.12/I²=0%), mean fluoroscopy time (MD=-0.14 CI -1.60, 1.32/I²=21%) and adverse events rates (RD=-0.06 CI: -0.14, 0.02/I²=0%), by contrast, the mean procedure time favored conventional therapy with statistical significance (MD=27.89 CI: 16.68, 39.10/I²=0%). In observational studies, the successful endoscopic clearance rate was 88.29% (CI95: 86.9%-90.7%), the first session successful endoscopic clearance rate was 72.7 % (CI95: 69.9%-75.3%), the mean procedure time was 47.50±6 min for session and the number of sessions to clear bile duct was 1.5±0.18. The adverse event rate was 8.7% (CI95: 7%-10.9%). CONCLUSIONS For complex common bile duct stones, cholangioscopy-guided lithotripsy has a success rate that is similar to traditional ERCP techniques in terms of therapeutic success, adverse event rate and means fluoroscopy time. Conventional ERCP methods have a shorter mean procedure time.

[PMID: 32179048 DOI: 10.1016/j.ajg.2019.12.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 12/03/2019] [Accepted: 12/05/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND STUDY AIM Since its inception in 2007, single-operator cholangioscopy (SOC) has gained popularity for many diagnostically and therapeutically challenging biliary and pancreatic conditions. Many studies have been published to evaluate the feasibility, usefulness, cost-effectiveness, and safety profile of the first generation. This paper is a descriptive study in which we aim to share the experience of two tertiary care centers with the novel version of SOC, SpyGlass DS. PATIENTS AND METHODS We retrospectively reviewed the records of all the patients who went through the procedure from October 2015 - July 2019 to explore the scope of biliary and pancreatic conditions in which SOC was utilized. Technical success was defined as the ability to visualize the lesion and complete the procedure as planned, whereas clinical success was determined by the ability to achieve the desired diagnostic/therapeutic outcome. RESULTS During the period of interest, 66 patients (34 males) went through 84 cholangioscopy procedures. Forty-four patients failed the conventional extraction methods and needed the intervention for the treatment of difficult stones, 24 patients needed a diagnostic evaluation of biliary strictures, and 3 needed an intervention to remove migrated stents. Technical success was achieved in 98.8% (83/84) of the procedures (95% CI: 96-100%). Regarding clinical success, stone breakdown and removal was achieved in 92% of the procedures (49/53; 95% CI: 85-100%). Tissue samples were successfully obtained in 95.8% (23/24) of patients with strictures (95% CI: 88-100%). The biopsy was appropriate to make a histological diagnosis in 83.3% of cases (20/24; 95% CI: 68-98%). The median number of sessions needed to achieve the deisred outcome was one (ranging between 1 and 6 sessions). CONCLUSION The new version of SOC, SpyGlass DS, provides a feasible and an effective option for the management of difficult cholelithiasis, as well as visually evaluating and obtaining histological samples for indeterminate biliary strictures. However, data from more extensive studies are needed to establish its non-inferiority to the fiberoptic version in terms of short- and long-term outcomes, cost-effectiveness, and complications.

Abstract
Direct visualization of bile and pancreatic duct pathology is proving to be beneficial in patients where previous techniques have failed. Recent advancements in technology and the development of the SpyGlass system have led to an increased use of cholangioscopy. It is already known that SpyGlass is beneficial in patients with difficult bile duct stones and indeterminate biliary lesions through the use of targeted lithotripsy and visually guided biopsy. Cholangioscopy allows the visualization of hidden stone and guide wire placement across difficult strictures and selective cannulation of the intrahepatic and cystic ducts. It is also demonstrating its utility in investigational applications such as post-liver transplant and primary sclerosing cholangitis stricture treatment, evaluation of hemobilia, and guided radiofrequency ablation of ductal tumors. In addition to having clinical utility, cholangioscopy may also be cost-effective by limiting the number of repeat procedures. Cholangioscopy overall has similar complication rates compared to other standard endoscopic retrograde cholangioscopy (ERCP) techniques, but there may be higher rates of cholangitis. This could be mitigated with prophylactic antibiotic use, and overall, cholangioscopy has similar complication rates compared to other techniques.

Abstract
BACKGROUND & AIMS Although single-operator cholangioscopy is considered to be the most sensitive method for tissue acquisition in patients with indeterminate bile duct strictures (IBDS), methods are needed to optimize the specimen collection and processing techniques. We aimed to determine the optimal method for specimen processing and identify the number of biopsies required to establish a definitive diagnosis. METHODS Patients with IBDS were randomly assigned to groups that underwent specimen processing using the onsite (n = 32) or offsite (n = 30) method. The primary outcome was to compare operating characteristics of onsite vs offsite specimen processing techniques. The secondary outcome was number of biopsies needed to establish definitive diagnosis. A final diagnosis was established at surgery or after a minimum clinical follow-up period of 18 months RESULTS: The final diagnosis was benign disease in 33 patients and malignancy in 29 patients. There were no significant differences between the offsite and onsite groups in diagnostic accuracy (90% vs 87.5%; P=.99), sensitivity (76.9% vs 75%; P=.99), specificity (100% vs 100%; P=.99), positive predictive value (100% vs 100%; P=.99), or negative predictive value (85% vs 80%; P=.99). Although diagnoses were established by analysis of a median of 1 biopsy in the onsite cohort (interquartile range, 1-1.5), the diagnostic accuracy was identical (90%) in each group, regardless of whether 3 or 4 biopsies were collected from each patient in the offsite cohort. CONCLUSIONS In a prospective comparative study, we found that centers without onsite cytopathology support that analyze 3 single-operator cholangioscopy-guided biopsies of a biliary stricture and process the specimens offsite make the correct diagnosis for 90% of cases.

Abstract
Endoscopic Retrograde Cholangiopancreatography (ERCP) remains the conventional method of imaging the pancreatic and biliary tree and is performed by direct injection of iodinated contrast material via the major papilla. This diagnostic procedure gained popularity in the 1970s and subsequently paved way for ERCP guided interventions such as sphincterotomy, stone retrieval and stent placement. Currently, therapeutic ERCP is more widespread than diagnostic ERCP primarily due to the availability of noninvasive imaging. Nevertheless, more than half a million ERCPs are performed annually in the United States and radiologists need to be comfortable interpreting them. The following review will familiarize the reader with the imaging appearances of biliary and pancreatic disorders on conventional ERCP, and elaborate on therapeutic ERCP with illustrative examples.

Abstract
Bile duct stones, indeterminate biliary strictures and other biliary duct pathologies represent a significant surgical and endoscopic challenge in patients with altered luminal or biliary anatomy. Traditional endoscopic retrograde cholangiopancreatography (ERCP) is not feasible and alternative approach is usually required. A novel alternative approach of addressing these challenging cases is assessed by this case series. All patients who underwent percutaneous transhepatic cholangioscopy (PTCS) and SpyglassTM Direct visualization system (SDVS) between December 2016 and February 2018 were studied. The indications for procedure, interventions performed, outcomes and complications were reviewed for each case. SpyglassTM marketed by Boston Scientific Corporation, Marlborough, Massachusetts was utilized by interventional endoscopists and radiologists through a 12 French (Fr) percutaneous vascular sheath. Five patients had altered biliary and/or luminal anatomy: two with Roux-en-Y gastric bypass and three with Roux-en-Y hepaticojejunostomy. All patients had unsuccessful previous ERCP attempts. All PTCS with SDVS procedures were technically successful. Indications for this unusual approach were: ascending cholangitis, abnormal liver function tests and biliary dilation on imaging. SDVS was utilized to conduct electrohydraulic lithotripsy (EHL) for biliary stone management in four patients and intraductal biopsies for indeterminate strictures in two of them. PTCS with SDVS can be beneficial for multiple diagnostic and therapeutic indications in patients with altered biliary or luminal anatomy. SDVS allows direct evaluation and management of different biliary pathologies in challenging cases where traditional ERCP is not feasible. Some indications for PTCS with SDVS include evaluation of biliary strictures and biliary stasis, biliary tract biopsy and lithotripsy for management of biliary stones.

Abstract
BACKGROUND/AIMS The use of cholangioscopy for the diagnosis and treatment of hepatobiliary diseases is gradually becoming more common. We aimed to review our peroral cholangioscopy interventions, using the first-generation SpyGlass Direct Visualization System (SDVS) and summarize our experience in terms of procedures and results. MATERIALS AND METHODS Forty-one patients who underwent this procedure at our Gastroenterology Clinic between February 2010 and October 2014 were included in this study. Patients were monitored for a median (IQR) of 44 (range 38-72) months. Demographic characteristics of these patients, results of the radiological and biochemical evaluation performed prior to the procedure, cholangioscopy findings together with the data relating to the procedure, histopathological diagnosis, clinical findings and results, and their effects on patient prognosis were assessed. RESULTS In total, 41 patients underwent 46 cholangioscopy procedures. Of them, 21 (51.2%) were male. The most frequent clinical indications for cholangioscopy was the need to further investigate indeterminate stricture (n=16; 39%) and indeterminate filling defect (n=7; 17.1%). The procedure was considered successful in 39 patients with 41 (95.1%) receiving diagnostic and 33 (80.5%) receiving therapeutic benefits. The sensitivity and specificity for SVDS-guided biopsies and brush cytology were 80% and 87.5%; 26.6% and 75%, respectively. Complications related to the procedure occurred in a total of three patients (7.3%), two with cholangitis and one with perforation of gall bladder. CONCLUSION Our experience shows that cholangioscopy procedures, performed with SDVS, are clinically applicable and safe in the diagnosis and treatment of hepatobiliary diseases.

Abstract
INTRODUCTION Brush cytology is commonly used during endoscopic retrograde cholangiopancreatography for the diagnostic evaluation of biliopancreatic strictures. However, since the overall sensitivity of brush cytology is poor, the exclusion of malignancy is difficult. Recognition of factors related to the patient, technique or lesion may help improve the diagnostic yield of brush cytology. The objective of this study was to evaluate the diagnostic yield of brush cytology in the assessment of biliopancreatic strictures and identify predictive factors associated with a positive diagnosis of malignancy. METHODS Retrospective study that evaluated all consecutive patients that underwent brush cytology for the investigation of biliopancreatic strictures in a tertiary center, between January 2012 and January 2018. RESULTS One hundred and sixty-five patients that underwent 182 procedures were included. A diagnosis of malignancy was confirmed in 110 patients (66.7%), of whom 62 had positive brush cytology (sensitivity 53.7%, specificity 98.5%, accuracy 69.8%). On the multivariate analysis, age ≥68 years (OR 4.83, 95% CI 1.04-22.37) and lesions suspicious of metastasis on cross-sectional imaging (OR 8.58, 95% CI 1.70-43.38) were independently associated with a positive result. Subanalysis of the patients presenting with these two factors (n = 26) revealed an increase in the diagnostic yield (sensitivity 80.8%). CONCLUSION Age ≥68 years and lesions suspicious of metastasis on cross-sectional imaging are independent factors associated with a positive result. Patient selection taking these factors into account may increase the diagnostic yield of brush cytology.

Abstract
Biliary strictures are considered indeterminate when the initial radiologic evaluation and endoscopic retrograde cholangiopancreatography with brush cytology and/or forceps biopsy do not reveal diagnostic findings. Evaluation of these strictures is challenging and often requires a multidisciplinary approach and multiple procedures. Peroral cholangioscopy allows direct visualization of these lesions and targeted tissue acquisition using miniature biopsy forceps. In the past decade, there have been significant improvements in the field of cholangioscopy. These advances have allowed higher-quality image acquisition, easy setup, operation by a single operator, easy maneuverability, and excellent targeted tissue sampling performance. However, the interpretation of cholangioscopic visual findings remains challenging. In this review, we discuss the role of peroral cholangioscopy in the evaluation of indeterminate biliary strictures.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, idiopathic, cholestatic liver disease characterized by inflammation and fibrosis of the intrahepatic and/or extrahepatic bile ducts. It can affect individuals of all age groups and gender, has no established pharmacotherapy, and is associated with a variety of neoplastic (e.g. cholangiocarcinoma) and non-neoplastic (e.g. dominant strictures) hepatobiliary complications. Given these considerations, endoscopy plays a major role in the care of patients with PSC. In this review, we discuss and provide updates regarding endoscopic considerations in the management of hepatobiliary manifestations and complications of PSC. Where evidence is limited, we suggest pragmatic approaches based on currently available data and expert opinion.

Abstract
Cholangiocarcinoma (CCA) is a heterogeneous group of tumours, derived from cells of the biliary tree, which represent the second most frequent primary liver tumour. According to the most recent classifications, CCA can be subdivided into intrahepatic (iCCA) and extrahepatic (eCCA) which include perihilar (pCCA) and distal (dCCA) CCA. CCA are usually identified at advanced stages, when the primary tumour grows enough to produce a large liver mass or when jaundice has developed because of biliary tree obstruction. The ongoing challenges in the identification of risk factors and definition of a specific population at higher risk of developing CCA are the main challenges for the development of screening programs. Therefore, late diagnosis remains an unresolved issue in CCA. Imaging plays an important role in the detection and characterization of CCA, helping with radiological diagnosis, guiding biopsy procedures and allowing staging of the tumour. This review focuses on clinical presentations and diagnosis and staging techniques of CCA.

Abstract
BACKGROUND AND AIM Current evidence supporting the utility of single-operator peroral cholangioscope (SOPOC) in the management of difficult bile duct stones is limited. We conducted the present systematic review and meta-analysis to evaluate the efficacy and safety of SOPOC in treating difficult bile duct stones. METHODS We searched studies up to April 2018, using MEDLINE, EMBASE, the Cochrane Library, and Google Scholar. Quality assessment of the studies was completed with the Newcastle-Ottawa Scale. Main outcomes were complete stone clearance rate, single-session stone clearance rate, number of endoscopic sessions needed for stone clearance, and adverse events. We calculated the pooled estimates with random-effects models. Potential publication bias was assessed. RESULTS Twenty-four studies involving 2786 patients met the inclusion criteria. Pooled proportion of patients with complete stone clearance was 94.3% (95% confidence interval [95% CI]: 90.2-97.5%). Single-session stone clearance was achieved in 71.1% (95% CI: 62.1-79.5%) of the pooled patients. Pooled number of sessions needed for stone clearance was 1.26 (95% CI: 1.17-1.34%). Pooled adverse event rate was 6.1% (95% CI: 3.8-8.7%). Potential publication bias was detected but had no significant influence on the results. CONCLUSIONS Single-operator peroral cholangioscope is an effective and safe treatment for difficult bile duct stones when conventional methods have failed. More randomized controlled trials are warranted to confirm the results.

Abstract
Indeterminate biliary strictures pose a diagnostic and therapeutic challenge. Although underlying malignancy is a primary concern, biliary strictures may result from benign processes. An accurate diagnosis is paramount to define the treatment strategy and minimize morbidity. The limitations of traditional endoscopic retrograde cholangiopancreatography-based tissue acquisition with cytology brushings are well-documented. Endoscopic retrograde cholangiopancreatography is generally unable to determine a stricture's etiology. Complementary advanced endoscopic imaging and multimodal tissue acquisition have evolved. Careful consideration of the clinical presentation, location of the stricture, and interpretation of imaging constitute the most optimal approach for diagnosis and management.

Abstract
INTRODUCTION This study examined the efficacy and safety of cholangiopancreatoscopy via the SpyGlass™ system in routine clinical practice. METHODS The clinical data of endoscopic retrograde cholangiopancreatography (ERCP) performed in a regional hospital from January 2013 to November 2016 was retrieved from an electronic database and reviewed. All patients who had undergone SpyGlass cholangiopancreatoscopy were enrolled. Patient demographics, procedure indication, technical success rates, clinical success rates and complication rates were analysed. A subanalysis of clinical outcomes was performed comparing the SpyGlass legacy (fibreoptic) and digital systems. RESULTS Out of 2,050 ERCP procedures performed, 47 patients underwent 50 cholangiopancreatoscopy procedures. Clinical indications were difficult common bile duct (CBD) stones (59.6%, n = 28), indeterminate CBD stricture (36.2%, n = 17), indeterminate pancreatic duct stricture (2.1%, n = 1) and proximally migrated CBD stent (2.1%, n = 1). Complete stone extraction was achieved in 26 (92.9%) out of 28 patients. Among patients with strictures, a correct diagnosis of malignancy based on image visualisation was achieved in all 11 cases. The sensitivity and specificity for SpyBite™ biopsies were 81.8% (95% confidence interval [CI] 48.2%-97.7%) and 100.0% (95% CI 15.8%-100.0%), respectively. The proximally migrated CBD stent was successfully extracted. Complications included pancreatitis (2.1%, n = 1), suspected sealed perforation after laser lithotripsy treated conservatively (2.1%, n = 1) and cholangitis (10.6%, n = 5). There was no difference in clinical outcomes between the SpyGlass legacy (n = 20) and digital (n = 30) systems. CONCLUSION SpyGlass cholangiopancreatoscopy is a safe and effective tool in routine clinical practice.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) remains the gold standard for the diagnosis and treatment of biliopancreatic disorders, and over one million ERCP procedures are performed each year worldwide. ERCP has always been performed by a group of courageous endoscopists who on a daily basis managed to develop its full diagnostic and therapeutic potential over the technique's 50 years of lifespan, always making the most of radiographic images, ever secretly dreaming of directly viewing the banned, consigned-to-oblivion territory.

Abstract
Background and study aims A newly developed peroral cholangioscopy (POCS) system, SpyGlassDS has high maneuverability. This study aimed to evaluate acceptability of the accuracy of SpyGlassDS accompanied by simultaneous POCS-guided biopsy compared with that of a traditional POCS scope, CHF-B260, to diagnose the lateral extent of extrahepatic cholangiocarcinoma (LEC). Patients and methods Patients who underwent surgical resection after preoperative examinations to diagnose LEC were evaluated. POCS by CHF-B260 was performed if there was discrepancy between preceding fluoroscopy-guided biopsy findings and other examinations between January 2004 and September 2015 (group A, n = 56); and POCS plus POCS-guided mapping biopsy by SpyGlassDS was performed in all surgical candidates between October 2015 and December 2017 (group B, n = 20). The main outcome measure was the accuracy of overall preoperative diagnosis (OPD) of LEC defined based on all examinations, including POCS. Results Accuracy of OPD for the liver side and the ampullary side was 93 % and 100 %, respectively, in group A, and 84 % and 100 %, respectively, in group B ( P = 0.37 for the liver side; P , not available for the ampullary side). Diagnostic accuracy of simple optical evaluation by POCS for the liver side and the ampullary side was 83 % and 100 %, respectively, in group A, and 58 % and 88 %, respectively, in group B ( P = 0.29 for the liver side; P = 0.40 for the ampullary side). Conclusions POCS by SpyGlassDS was found to be acceptable and could be a standard approach for diagnosis of LEC.

Abstract
PURPOSE OF REVIEW Every year more than one million people worldwide undergo an endoscopic retrograde cholangiopancreatography (ERCP) for disorders of the bile duct system. This review aims to discuss recent clinical data with regard to single-operator peroral cholangioscopy (POC). RECENT FINDINGS Innovations and technical optimizations of POC devices have extended diagnostic and therapeutic options for patients with complex biliary disease. Most of the currently available clinically relevant data are obtained with the single-operator peroral cholangioscopy (SOC)-system SpyGlass, which in a period of a decade has evolved further to a digital platform with increasing applicability, usefulness and cost-effectiveness. SUMMARY POC allows endoscopists to treat patients with complicated diseases of the gallbladder, liver, biliary tract, and pancreas better. In recent years, this technique was optimized to overcome prior limitations. The implementation of the single-operator SpyGlass Digital System in daily practice becomes a reality. We make an overview of the history of cholangioscopy, the technical evolution, and usefulness of this platform and take a look at its economic impact.

Abstract
BACKGROUND/OBJECTIVES It is often difficult to determine an adequate resection line during pancreatectomy for intraductal papillary mucinous neoplasm involving the main pancreatic duct during partial pancreatectomy. The aim of this study was to evaluate the usefulness of improved peroral pancreatoscopy using SpyGlass-DStm in the preoperative assessment of intraductal papillary mucinous neoplasm involving the main pancreatic duct. METHODS We collected and retrospectively analyzed clinicopathological data from seven consecutive patients who underwent preoperative assessment of intraductal papillary mucinous neoplasm involving the main duct using SpyGlass-DStm. RESULTS Good imaging quality of the intraductal protruding lesion was obtained in all seven patients, and only one adverse event was noted wherein a patient had mild pancreatitis. Six patients underwent pancreatectomy. In one patient, masked-type concomitant pancreatic ductal adenocarcinoma and low-length dysplastic lesion was found near the surgical margin, which was not detected by preoperative imaging modalities including SpyGlass-DStm. The sensitivity of targeting biopsy during SpyGlass-DStm to diagnose high-grade dysplasia was 0%. CONCLUSIONS SpyGlass-DStm can be safely performed in patients with intraductal papillary mucinous neoplasm involving the main duct, and has excellent visualization of the target lesion. However, challenges include poor diagnostic ability of targeting biopsy, and, therefore, intraoperative frozen section is still needed to obtain negative surgical margins.

Review article: Asia-Pacific consensus recommendations on endoscopic tissue acquisition for biliary strictures. Aliment Pharmacol Ther 2018; 48:138-151.

Abstract
BACKGROUND Pre-operative tissue diagnosis for suspected malignant biliary strictures remains challenging. AIM To develop evidence-based consensus statements on endoscopic tissue acquisition for biliary strictures. METHODS The initial draft of statements was prepared following a systematic literature review. A committee of 20 experts from Asia-Pacific region then reviewed, discussed, and modified the statements. Two rounds of independent voting were conducted to reach a final version. Consensus was considered to be achieved when 80% or more of voting members voted "agree completely" or "agree with some reservation." RESULTS Eleven statements achieved consensus. The choice of tissue sampling modalities for biliary strictures depends on the clinical setting, the location of lesion, and availability of expertise. Detailed radiological and endoscopic evaluation is useful to guide the selection of appropriate tissue acquisition technique. Standard intraductal biliary brushing and/or forceps biopsy is the first option when endoscopic biliary drainage is required with an overall (range) sensitivity and specificity of 45% (26%-72%) and 99% (98%-100%), and 48% (15%-100%) and 99% (97%-100%), respectively, in diagnosing malignant biliary strictures. Probe-based confocal laser endomicroscopy and fluorescence in situ hybridisation using 4 fluorescent-labelled probes targeting chromosomes 3, 7, 17 and 9p21 locus may be added to improve the diagnostic yield. Cholangioscopy-guided biopsy and EUS-guided tissue acquisition can be considered after prior negative conventional tissue sampling with an overall (range) sensitivity and specificity of 60% (38%-88%) and 98% (83%-100%), and 80% (46%-100%) and 97% (92%-100%), respectively, in diagnosing malignant biliary strictures. CONCLUSION These consensus statements provide evidence-based recommendations for endoscopic tissue acquisition of biliary strictures.
