Abstract
Common bile duct (CBD) stone is a common biliary problem, which often requires endoscopic approach as the initial treatment option. Roughly, 7%-12% of the subjects who experience cholecystectomy were subsequently referred to biliary endoscopist for further management. In general, there are three classifications of difficult CBD stone, which are based on the characteristics of the stone (larger than 15 mm, barrel or square-shaped stones, and hard consistency), accessibility to papilla related to anatomical variations, and other clinical conditions or comorbidities of the patients. Currently, endoscopic papillary large balloon dilation (EPLBD) of a previous sphincterotomy and EPLBD combined with limited sphincterotomy performed on the same session is still recommended by the European Society of Gastrointestinal Endoscopy as the main approach in difficult CBD stones with history of failed sphincterotomy and balloon and/or basket attempts. If failed extraction is still encountered, mechanical lithotripsy or cholangioscopy-assisted lithotripsy or extracorporeal shockwave lithotripsy can be considered. Surgical approach can be considered when stone extraction is still failed or the facilities to perform lithotripsy are not available. To our knowledge, conflicting evidence are still found from previous studies related to the comparison between endoscopic and surgical approaches. The availability of experienced operator and resources needs to be considered in creating individualized treatment strategies for managing difficult biliary stones.

[PMID: 31349795 PMCID: PMC6660680 DOI: 10.1186/s12876-019-1045-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 07/11/2019] [Indexed: 12/17/2022] Open
Abstract
Background This study aims to evaluate the efficacy and safety of detecting and removing residual common bile duct stones (CBDS) using direct peroralcholangioscopy (DPOC) after performing endoscopic retrograde cholangiopancreatography (ERCP) for stone retrieval. Methods From January 5, 2017 to December 27, 2017, a total of 164 cases of choledocholithiasis were treated by ERCP for stone retrieval. According to the inclusion and exclusion criteria, the remaining 79 cases (39 males; mean age: 63.3 years old, range: 52–79 years old) were enrolled in the present study. The maximum transverse stone diameter was 6–15 mm (12.7 ± 4.2 mm), as determined by ERCP. Furthermore, there were 57 cases of multiple stones (number of stones: two in 41 cases, three in nine cases, and ≥ 4 in seven cases), 13 cases of post-mechanical lithotripsy, and nine cases of broken stones. Results The overall success rate of DPOC was 94.9% (75/79). Furthermore, 18.7%(14/75) of cases were directly inserted, 72%(54/75) of cases required guide wire assistance, and 9.3%(7/75) of cases were successfully inserted with overtube assistance. The average insertion time was 7–17 min (4.9 ± 2.9 min). Residual stones were detected in 19 cases (25.3%), and all of which were < 5 mm in diameter. Moreover, five cases of formed stones were removed by basket and balloon catheter, while the remaining cases were cleaned after irrigation and suction. There were no serious complications. Conclusion DPOC is safe and effective for both the detection and removal of residual CBDS after conventional ERCP.

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.

Abstract
OBJECTIVE To evaluate the feasibility, effectiveness and safety of a new snare-assisted peroral direct choledochoscopy/pancreatoscopy (PDCPS) technique. METHODS From November 2014 through December 2016, 20 consecutive patients with indications for PDCPS were enrolled in this observational study. Endoscopic retrograde cholangiography was initially performed using a conventional duodenoscope, and endoscopic papillary balloon dilation was performed. Next, an ultra-slim endoscope was inserted to perform the PDCPS; a snare tightened around the end of the scope's bending section facilitated its entry into the common bile duct (CBD). The primary endpoint was the overall success rate of the PDCPS procedure (successful biliary intubation and visualization of the area of interest) and the time for biliary intubation with the ultra-slim upper endoscope. RESULTS Participants (11 men and 9 women; mean age, 72.2 years [range, 41-93 years]) had CBD adenoma (n=1), large CBD stones after failed extraction/lithotripsy treatment (n=13), CBD strictures (n=4), pancreatic duct tumor (n=1) or pancreatic duct dilation (n=1). The success rate was 95%. The mean intubation time was 18min (range, 4-57min). No adverse events were reported. CONCLUSIONS A snare-assisted PDCPS technique appears to be technically feasible, effective and safe for both diagnostic and therapeutic applications.

Abstract
Some endoscopists have reported the usefulness of direct peroral cholangioscopy for the diagnosis and therapy of bile duct lesions. Advantages of direct peroral cholangioscopy (POC) using an ultra-slim endoscope include use of conventional endoscopy equipment, operation by a single endoscopist, and superior image quality of the biliary tree with easy application of enhanced endoscopy and a large working channel. Although ultra-slim endoscopes are usually used for direct peroral cholangioscopy, direct scope insertion is considerably difficult. Moreover, this technique still has some severe complications and limitations. Continuous development of specialized endoscopes and accessories is expected to facilitate the diagnostic and therapeutic roles of direct POC.

Abstract
Peroral cholangioscopy (POC) is an important tool for the management of a selected group of biliary diseases. Because of its direct visualization, POC allows targeted diagnostic and therapeutic procedures. POC can be performed using a dedicated cholangioscope that is advanced through the accessory channel of a duodenoscope or via the insertion of a small-diameter endoscope directly into the bile duct. POC was first described in the 1970s, but the use of earlier generation devices was substantially limited by the cumbersome equipment setup and high repair costs. For nearly ten years, several technical improvements, including the single-operator system, high-quality images, the development of dedicated accessories and the increased size of the working channel, have led to increased diagnostic accuracy, thus assisting in the differentiation of benign and malignant intraductal lesions, targeting biopsies and the precise delineation of intraductal tumor spread before surgery. Furthermore, lithotripsy of difficult bile duct stones, ablative therapies for biliary malignancies and direct biliary drainage can be performed under POC control. Recent developments of new types of conventional POCs allow feasible, safe and effective procedures at reasonable costs. In the current review, we provide an updated overview of POC, focusing our attention on the main current clinical applications and on areas for future research.

Abstract
Extraction of common bile duct stones by endoscopic retrograde cholangiopancreatography generally involves biliary sphincterotomy, endoscopic papillary balloon dilation or a combination of both. Endoscopic papillary large-balloon dilation after sphincterotomy has increased the safety of large stone extraction. Cholangioscopically directed electrohydraulic and laser lithotripsy using single-operator mother-daughter systems or direct peroral cholangioscopy using ultraslim endoscopes are increasingly utilized for the management of refractory stones. In this Review, we focus on advances in endoscopic approaches and techniques, with a special emphasis on management strategies for 'difficult' common bile duct stones.

Abstract
BACKGROUND Although peroral direct cholangioscopy (PDCS) is emerging as an alternative to traditional mother-daughter cholangioscopy, it is associated with high failure rates. The aim of the present study was to evaluate the ability to insert and carry out interventions using a prototype multi-bending PDCS. PATIENTS AND METHODS Prospective, observational clinical feasibility study was done in 41 patients with a variety of biliary diseases. A multi-bending PDCS prototype was inserted using a free-hand technique, a guidewire alone, or with a 5-Fr diameter anchoring balloon. Diagnostic and therapeutic procedures were carried out. RESULTS The free-hand direct insertion technique failed in all attempted cases (n = 7). Of the remaining 34 cases, successful rate of PDCS insertion into the distal bile duct was achieved by passing the PDCS over a guidewire alone (n = 6) and/or with a guidewire plus anchoring balloon (n = 28) for an overall successrate of 88.2% (30/34). In 13 (92.9%) patients without an underlying biliary stricture, PDCS insertion proximal to the bifurcation was possible. In 25 cases, biliary interventions were attempted including biopsy (n = 13), stone removal (n = 6), stent removal (n = 1), and intraductal electrohydraulic lithotripsy (n = 2) and were successful in 22 (88%). Other than two patients with procedure-related cholangitis with a mild grade of severity, no complications were observed. CONCLUSIONS Using a novel multi-bending prototype peroral direct cholangioscope, cholangioscopy had a high diagnostic and therapeutic success rate only when passed over a guidewire and anchoring balloon but not with the free-hand insertion technique. Comparative studies of direct cholangioscopy are warranted.

Abstract
BACKGROUND Mother-baby technologies, the criterion standard for cholangioscopy, have several limitations. A novel, short-access, mother-baby (SAMBA) system may improve this technique. Direct cholangioscopy (DC) was recently developed as an alternative to mother-baby cholangioscopy. OBJECTIVE Comparison of success rates with SAMBA and DC. DESIGN Single-center, randomized, controlled trial. SETTING Academic tertiary-care referral center. PATIENTS Sixty patients with suspected cholangiopathies randomized to either SAMBA (n = 30) or DC (n = 30). INTERVENTION Cholangioscopy under deep sedation. MAIN OUTCOME MEASUREMENTS Technical success rate of diagnostic or therapeutic procedure. RESULTS A total of 24 and 21 diagnostic procedures were performed in the SAMBA and DC groups, respectively. There were no significant differences in the overall technical success rates between SAMBA (90.0%) and DC (86.7%) (P = 1.0). There was better correlation between the endoscopic prediction and histologic findings in DC (P = .013). Procedure times were shorter in DC (P < .03). In patients without significant stenoses, SAMBA allowed intrahepatic bile duct exploration in all cases, compared with 10.5% of cases in DC (P < .01). No differences regarding adverse event rates between the groups occurred (10.0% both groups). LIMITATIONS Small sample size. Heterogeneous indications for cholangioscopy. DC requires advanced skills of the endoscopist. The study is not replicable. CONCLUSION SAMBA and DC offer high technical success rates for diagnostic and therapeutic interventions. The advantages of DC consist of superior imaging, shorter total procedure time, and a wider working channel for adequate tissue sampling. SAMBA is better than DC with regard to intraductal stability and accessibility of the intrahepatic bile ducts.

Abstract
AIM: To detect and manage residual common bile duct (CBD) stones using ultraslim endoscopic peroral cholangioscopy (POC) after a negative balloon-occluded cholangiography.
METHODS: From March 2011 to December 2011, a cohort of 22 patients with CBD stones who underwent both endoscopic retrograde cholangiography (ERC) and direct POC were prospectively enrolled in this study. Those patients who were younger than 20 years of age, pregnant, critically ill, or unable to provide informed consent for direct POC, as well as those with concomitant gallbladder stones or CBD with diameters less than 10 mm were excluded. Direct POC using an ultraslim endoscope with an overtube balloon-assisted technique was carried out immediately after a negative balloon-occluded cholangiography was obtained.
RESULTS: The ultraslim endoscope was able to be advanced to the hepatic hilum or the intrahepatic bile duct (IHD) in 8 patients (36.4%), to the extrahepatic bile duct where the hilum could be visualized in 10 patients (45.5%), and to the distal CBD where the hilum could not be visualized in 4 patients (18.2%). The procedure time of the diagnostic POC was 8.2 ± 2.9 min (range, 5-18 min). Residual CBD stones were found in 5 (22.7%) of the patients. There was one residual stone each in 3 of the patients, three in 1 patient, and more than five in 1 patient. The diameter of the residual stones ranged from 2-5 mm. In 2 of the patients, the residual stones were successfully extracted using either a retrieval balloon catheter (n = 1) or a basket catheter (n = 1) under direct endoscopic control. In the remaining 3 patients, the residual stones were removed using an irrigation and suction method under direct endoscopic visualization. There were no serious procedure-related complications, such as bleeding, pancreatitis, biliary tract infection, or perforation, in this study.
CONCLUSION: Direct POC using an ultraslim endoscope appears to be a useful tool for both detecting and treating residual CBD stones after conventional ERC.

Abstract
Endoscopy is widely accepted as the first treatment option in the management of bile duct stones. In this review we focus on the alternative endoscopic modalities for the management of difficult common bile duct stones. Most biliary stones can be removed with an extraction balloon, extraction basket or mechanical lithotripsy after endoscopic sphincterotomy. Endoscopic papillary balloon dilation with or without endoscopic sphincterotomy or mechanical lithotripsy has been shown to be effective for management of difficult to remove bile duct stones in selected patients. Ductal clearance can be safely achieved with peroral cholangioscopy guided laser or electrohydraulic lithotripsy in most cases where other endoscopic treatment modalities have failed. Biliary stenting may be an alternative treatment option for frail and elderly patients or those with serious co morbidities.

Abstract
INTRODUCTION Direct peroral cholangioscopy (DPOCS) was reported to present clinical potential, and creating a target-specific training program for biliary endoscopists who lack experience with DPOCS is an important task. METHODS This prospective and observational study used five male domestic pigs. Optimal procedures were decided after pilot tests using an in vivo live porcine model. A total of three ERCP men were enrolled into the training program. The objective parameters, including the rate of success and complications, and the length of the procedure, were recorded for each participant. RESULTS In the training program, all the trainees successfully performed DPOCS and biopsies without significant complications. Close observation, free discussions, and the sharing of experiences helped shorten the total procedure time from 37.3 to 18.5 min. CONCLUSIONS This training program is a feasible approach to help biliary endoscopists acquire the experience for DPOCS with the ultrathin endoscope.

Abstract
Double-balloon enteroscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) is an effective endoscopic approach for pancreatobiliary disorders in patients with altered gastrointestinal anatomy. Endoscopic interventions via DBE in these postoperative settings remain difficult because of the lack of an elevator and the use of extra-long ERCP accessories. Here, we report the usefulness of direct cholangioscopy with an ultra-slim gastroscope during DBE-assisted ERCP. Three patients with choledocholithiasis in postoperative settings (two patients after Billroth II gastrojejunostomy and one patient after Roux-en-Y gastrojejunostomy) were treated. DBE was used to gain access to the papilla under carbon dioxide insufflation, and endoscopic sphincterotomy was performed with a conventional sphincterotome. For direct cholangioscopy, the enteroscope was exchanged for an ultra-slim gastroscope through an incision in the overtube, which was inserted directly into the bile duct. Direct cholangioscopy was used to extract retained bile duct stones in two cases and to confirm the complete clearance of stones in one case. Bile duct stones were eliminated with a 5-Fr basket catheter under direct visual control. No adverse events were noted in any of the three cases. Direct cholangioscopy with an ultra-slim gastroscope facilitates subsequent treatment within the bile duct. This procedure represents another potential option during DBE-assisted ERCP.

Abstract
PURPOSE OF REVIEW Endoscopic diagnosis of biliary disease is challenging due to difficulties in access, visualization, and sampling. Recent advances in endoscopic technology, ancillary diagnostic methods, and our understanding of autoimmune pancreatitis (AIP) and IgG4-related cholangitis (IRC) have led to improvements in the endoscopic diagnosis of pancreaticobiliary disease. RECENT FINDINGS Single-operator cholangioscopy overcomes several of the limitations of mother-baby cholangioscopy enhancing the diagnostic accuracy in indeterminate pancreaticobiliary disease. Probe-based confocal laser endomicroscopy has been recently shown to provide a significantly higher accuracy for the diagnosis of malignant biliary strictures than achieved by endoscopic retrograde cholangiopancreatogram and standard tissue acquisition, and has the potential to develop into a useful adjunct method of cholangioscopy. Fluorescence in-situ hybridization increases the sensitivity of routine brush cytology without compromising specificity in patients with indeterminate biliary strictures. The diagnosis of AIP/IRC remains challenging. The recently published international consensus criteria for AIP have included data on the potential diagnostic utility of endoscopic retrograde pancreatogram and endoscopic ampullary biopsies. SUMMARY Recent technical advances as well as ancillary diagnostic methods have improved the diagnostic accuracy of conventional endoscopic techniques. Future refinement of endoscopic methods may further improve diagnostic approaches to biliary disease.

Abstract
OBJECTIVES Despite an increase in the reports of intraductal papillary neoplasm of the bile duct (IPN-B), the clinical characteristics and long-term prognosis of this disease are not well known compared with those of intraductal papillary mucinous neoplasms of the pancreas. The objective of our study was to compare the clinical features, radiologic findings, and clinical outcomes of IPN-B according to histologic subtype. METHODS A retrospective analysis was performed on the medical records of 97 patients diagnosed with IPN-B by pathologic analysis of their surgical specimens between May 1995 and May 2010. We compared the clinical manifestations, radiological findings, pathologic grade, curative resection rate, recurrence, and overall survival according to four histologic subtypes: gastric (n=15), intestinal (n=46), pancreaticobiliary (n=33), and oncocytic (n=3), which were classified on the basis of hematoxylin and eosin staining and the immunohistochemical profile of mucin core proteins. RESULTS Mucin hypersecretion was significantly more frequent in patients with gastric and intestinal types than it was in those with oncocytic and pancreaticobiliary types (P=0.014). There were no significant differences between groups regarding the presence of bile duct stones or tumor location. The frequency of invasive carcinoma in the pancreaticobiliary type was significantly higher than those in the gastric and intestinal types (72.7 vs. 26.7 and 32.6%, P<0.001 and P<0.001). When comparing the survival curves according to histologic subtype, patients with pancreaticobiliary type demonstrated significantly worse survival compared to those with gastric and intestinal types (P=0.035). CONCLUSIONS Gastric and intestinal types of IPN-B have similar clinical characteristics compared with the pancreaticobiliary type, which has a worse prognosis.

Direct transnasal cholangioscopy with ultraslim endoscopes: a one-step intraductal balloon-guided approach. Gastrointest Endosc 2011; 74:309-16. [PMID: 21689814 DOI: 10.1016/j.gie.2011.02.022] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2010] [Accepted: 02/25/2011] [Indexed: 02/08/2023]
Abstract
BACKGROUND Direct cholangioscopy using an ultraslim endoscope is an attractive alternative to the conventional mother-baby endoscope system because it provides a single-operator platform and high-resolution image quality and allows advanced therapeutic interventions. However, biliary access is cumbersome and usually requires previous guidewire placement via retrograde cholangiography. OBJECTIVE To evaluate the feasibility of a 1-step transnasal cholangioscopy (TNC) technique using an ultraslim endoscope with an intraductal balloon to maintain access without previous guidewire placement. DESIGN Prospective, observational clinical feasibility study. SETTING Single tertiary referral center. MAIN OUTCOME MEASUREMENTS Overall procedure success rates and complications. A successful procedure was defined as one in which the endoscope was advanced into the bifurcation or stenotic segment of the biliary system. PATIENTS AND METHODS Twenty-five patients with biliary disease and previous sphincterotomy underwent direct TNC. RESULTS TNC was successful in 18 of the 25 patients (72%). The procedure revealed 3 common bile duct stones, 4 benign biliary strictures, 1 intraductal adenoma, and 3 cholangiocarcinomas. Eight patients underwent forceps biopsies under direct visualization, and 7 patients underwent therapeutic interventions, including argon plasma coagulation (n = 2), laser lithotripsy (n = 1), stent (n = 1), and stone extraction (n = 3). Other than 1 patient with procedure-related cholangitis, no complications were observed. LIMITATIONS Small number of patients and no comparison with conventional cholangioscopy. CONCLUSIONS One-step TNC with an ultraslim endoscope allows direct visual examination and therapeutic intervention in the bile ducts in the majority of patients with biliary disease. However, development of further accessory instruments will be needed to improve the success rate.

Abstract
Here, we report a case of a pancreatobiliary (PB) fistula caused by an intraductal papillary mucinous neoplasm (IPMN) of the pancreas. The PB fistula was suspected after endoscopic retrograde cholangiopancreatography (ERCP) and diagnosed after direct visualization with a direct peroral cholangioscopy and pancreatoscopy by using an ultra-slim endoscope. No previous reports exist on the precise diagnosis of a PB fistula with direct peroral cholangioscopy and pancreatoscopy. In our case report, a 69-year-old man underwent an ERCP because of a pancreatic head mass and biliary tract obstruction. During ERCP, a fistula between the common bile duct (CBD) and main pancreatic duct (MPD) was suspected. After endoscopic sphincterotomy, we examined both the CBD and MPD with an ultra-slim videoendoscope (GIF-N260; Olympus Optical Co, Tokyo, Japan) under direct visualization and biopsy of the mass. The analysis of the biopsy specimen confirmed this mass to be an IPMN of the pancreas. When we examined the CBD, one fistula with copious mucin secretion was identified at the distal CBD. In conclusion, direct peroral cholangioscopy and pancreatoscopy using the ultra-slim endoscope is an efficient tool for diagnosis of PB fistula and pancreatic IPMN.

Abstract
Direct endoscopic views of bile duct have been described in literature since the 1970s. Since then rapid strides have been made with the advent of technologically advanced systems with better image quality and maneuverability. The single operator semi-disposable per-oral cholangioscope and other novel methods such as the cholangioscopy access balloon are likely to revolutionize this field. Even though cholangioscopy is currently used primarily for characterization of indeterminate strictures and management of large bile duct stones, the diagnostic and therapeutic indications are likely to expand in future. The following is an overview of the currently available per-oral cholangioscopy equipments, indications for use and future directions.
