Abstract
BACKGROUND Disposable digital single-operator cholangioscopy (D-SOC) and direct peroral cholangioscopy (D-POC) using an ultraslim endoscope are established POC modalities for the diagnosis and treatment of various biliary diseases. We compared the usefulness of D-SOC and D-POC for the diagnosis of intraductal superficial lesions of the bile duct (ISL-Bs). METHODS 38 consecutive patients with suspected biliary diseases who underwent both D-SOC and D-POC were enrolled. The primary outcome was ISL-B detection rate, and the secondary outcomes were technical success of POC and POC-guided forceps biopsy sampling (POC-FB), procedure time, visualization quality, and tissue adequacy. RESULTS D-SOC had a higher technical success rate than D-POC but the difference was not statistically significant (100% vs. 92.1%, P = 0.25). D-POC had a marginally higher ISL-B detection rate (34.2% vs. 28.9%, P = 0.68) and significantly higher visualization quality (P = 0.03). The mean (SD) procedure time was significantly shorter with D-SOC (11.00 [1.33] vs. 19.03 [2.95] minutes, P<0.001). The technical success rate of POC-FB and tissue adequacy did not differ between the two techniques (D-SOC vs. D-POC: 81.8% vs. 84.6%, P = 0.69 and 77.8% vs. 90.9%, P = 0.57, respectively). CONCLUSIONS Both POC systems were safe and useful for the detection, characterization, and diagnosis of minute ISL-Bs. While D-SOC displayed a shorter procedure time and a tendency for higher technical success rate, D-POC provided superior visualization quality, allowing detailed observation of the surface structure and microvascular patterns.

Abstract
Background and study aims Digital single-operator cholangioscopy (DSOC) allows the diagnosis of biliary duct disorders and treatment for complicated stones. However, these technologies have limitations such as the size of the probe and working channel, excessive cost, and low image resolution. Recently, a novel DSOC system (eyeMAX, Micro-Tech, Nanjing, China) was developed to address these limitations. We aimed to evaluate the usefulness and safety of a novel 9F and 11F DSOC system in terms of neoplastic diagnostic accuracy based on visual examination, ability to evaluate tumor extension and to achieve complete biliary stone clearance, and procedure-related adverse events (AEs). Patients and methods Data from ≥ 18-year-old patients who underwent DSOC from July 2021 to April 2022 were retrospectively recovered and divided into a diagnostic and a therapeutic cohort. Results A total of 80 patients were included. In the diagnostic cohort (n = 49/80), neovascularity was identified in 26 of 49 patients (46.9%). Biopsy was performed in 65.3% patients with adequate tissue sample obtained in 96.8% of cases. Biopsy confirmed neoplasia in 23 of 32 cases. DSOC visual impression achieved 91.6% sensitivity and 87.5% specificity in diagnosing neoplasms. In the therapeutic cohort (n = 43/80), 26 of 43 patients required lithotripsy alone. Total stone removal was achieved in 71% patients in the first session. Neither early nor late AEs were documented in either the diagnostic or therapeutic cohort. Conclusions The novel DSOC device has excellent diagnostic accuracy in distinguishing neoplastic biliary lesions as well as therapeutic benefits in the context of total stone removal, with no documented AEs.

Abstract
BACKGROUND AND STUDY AIM The development of a new cholangioscope, the SpyGlass™ Discover (Boston Scientific), has allowed the laparoscopic transcystic common bile duct exploration and stone clearance. The possibility of simultaneous treatment of choledocholithiasis during early laparoscopic cholecystectomy offers the opportunity to enormously reduce the time between acute cholecystitis diagnosis and the execution of cholecystectomy with better outcomes for patients. Furthermore, an altered anatomy of the gastrointestinal tract is not an obstacle to this technique. The aim of the study was to determine whether this new procedure is feasible, safe, and effective. PATIENTS AND METHODS The investigation employs a retrospective case series study including all consecutive patients with a diagnosis of common bile duct stones undergoing cholecystectomy and intraoperative laparoscopic common bile duct clearance using SpyGlass™ Discover at IRCCS Policlinico San Matteo in Pavia (Italy). Eighteen patients were included from May 2022 to May 2023. RESULTS A complete clearance of the common bile duct was obtained in 88.9% of patients. The mean postoperative length of stay was 3 days. No major complications occurred. After a median follow-up of 8 months, no recurrence of biliary events or readmissions occurred. CONCLUSION This procedure has proven to be feasible, safe, and effective.

Abstract
Pancreatic duct (PD) stent migration is among the recognized complications of endoscopic retrograde cholangiopancreatography (ERCP) with PD stent placement. Proximal stent migration poses a challenge for removal due to risks of PD damage, smaller caliber, and possible stricture. Here, we present a case of SpyGlass DS system-assisted PD stent repositioning after failure with traditional tools.

Abstract
To evaluate the diagnostic accuracy of improved fluoroscopy-guided biopsies for indeterminate biliary strictures (IBDS). A multi-center retrospective study was performed. Patients with IBDS who underwent digital single-operator cholangioscopy (DSOC) and improved fluoroscopy-guided biopsies procedures were included. The individual sensitivity, specificity, and accuracy were analyzed. A total of 67 patients were enrolled in this multi-center retrospective study. The DSOC and improved fluoroscopy-guided biopsies procedures were successfully performed in all cases (100%). The sensitivity, specificity, and accuracy values were 83.3%, 89.5%, and 85.1% for DSOC visual impression; 95.8%, 94.7%, and 95.5% for improved fluoroscopy-guided biopsies procedures, respectively. The sensitivity and accuracy of improved fluoroscopy-guided biopsies were significantly higher compared with DSOC visual impression. Four patients (6.0%, 4/67) occurred adverse events after the procedures. Improved fluoroscopy-guided biopsies had a high diagnostic accuracy of IBDS diagnosis.

Zhang W, Sun H, Dong D, Li Y. Safety and feasibility of a novel recanalization technique using guidewire puncture under cholangioscopy for complete biliary stricture after liver transplantation. Sci Rep 2023; 13:4874.

Abstract
Cholangioscopy is reportedly useful for selective guidewire placement across difficult biliary strictures, but few methods are available for complete stricture of biliary anastomosis. This study aimed to propose a guidewire puncture technique to recanalize totally obstructed anastomosis and discuss its safety and feasibility. From January 2015 to December 2021, a total of 11 patients with complete biliary anastomotic stricture after liver transplantation were enrolled. These patients underwent peroral single operator cholangioscopy (SpyGlass), whereas two failed cases on SpyGlass finally underwent percutaneous transhepatic cholangioscopy (PTCS). The steps of the recanalization technique were as follows: the stricture was viewed carefully to detect the closure point (CP) of the scar endoscopically, then the CP was targeted by the hard tip of the guidewire and broke through under guidance of the cholangioscope and fluoroscope. Complete occlusions were confirmed by SpyGlass in all cases. A total of 13 hard-tip guidewire punctures were performed under cholangioscopy, and ten punctures were successful (technical success rate, 76.9% [10/13]). After recanalization of the occluded anastomosis, plastic stent or metallic stent was deployed in three and seven patients, respectively. No procedure-related complications occurred during or after the cholangioscopy-assisted guidewire puncture. After a mean follow-up of 12 months, stents had been removed in five patients. The other six patients were still receiving stent treatment. This study demonstrated that the guidewire puncture technique under cholangioscopy is safe and feasible for complete stricture of biliary anastomosis, and the success rate is satisfactory.

Diagnostic usefulness of SpyGlass in intracholecystic papillary neoplasm with pancreaticobiliary maljunction: a case report and comparison with conventional gallbladder cancer with pancreaticobiliary maljunction. Clin J Gastroenterol 2023; 16:476-481.

Abstract
BACKGROUND Intracholecystic papillary neoplasm (ICPN) is one of the precursors of gallbladder cancer defined in the 2010 World Health Organization classification of tumors. We herein report ICPN with pancreaticobiliary maljunction (PBM), which is a high-risk factor for biliary cancer. CASE PRESENTATION A 57-year-old female presented with abdominal pain. Computed tomography showed a swollen appendix and gallbladder nodules with bile duct dilatation. Endoscopic ultrasonography revealed a gallbladder tumor spreading into the cystic duct confluence accompanying PBM. Based on papillary tumors around the cystic duct detected using the SpyGlass DS II Direct Visualization System (SpyGlass DS), ICPN was suspected. We performed extended cholecystectomy, extrahepatic bile duct resection, and appendectomy with a diagnosis of ICPN and PBM. The pathological diagnosis was ICPN (90 × 50 mm) with high-grade dysplasia spreading into the common bile duct. The absence of residual cancer in the resected specimen was pathologically confirmed. P53 staining was totally negative in both the tumor and normal epithelium. The overexpression of CTNNB1 was not observed. CONCLUSIONS We encountered a patient with a very rare gallbladder tumor, ICPN with PBM. SpyGlass DS contributed to a precise assessment of the extent of the tumor as well as a qualitative diagnosis.

Abstract
BACKGROUND/PURPOSE A peroral cholangioscope (POCS) can allow direct visualization of the biliary mucosa and its use is becoming more widespread due to improvements in functionality, image quality, and operability, as well as the development of related devices. Recently, a novel mother-baby peroral cholangioscope (nMB-POCS) with a large (2-mm) accessory channel has been developed. In this study, we evaluated the feasibility of this novel POCS in a dry simulation and animal model. METHODS We evaluated the ease of insertion and maneuverability of the nMB-POCS, the image quality, and the passage of the devices into the accessory channel and into the common bile duct in a dry and live porcine model. RESULTS In both models, the nMB-POCS could be easily inserted into the duodenoscope and into the distal bile duct and hilum. The image quality was good, and it was possible to observe the surface structure and the vascular network of the bile duct mucosa in detail. CONCLUSIONS The nMB-POCS with its larger accessory channel is expected to improve the efficiency of diagnosis and treatment, and reduce the procedure time. Clinical studies in patients are warranted.

Electrohydraulic lithotripsy through endoscopic retrograde cholangiopancreatography combined with SpyGlass in the treatment of complex pancreatic duct stones: A case report and literature review. Front Surg 2023; 10:1059595. [PMID: 36741501 PMCID: PMC9889859 DOI: 10.3389/fsurg.2023.1059595] [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: 10/01/2022] [Accepted: 01/02/2023] [Indexed: 01/19/2023] Open
Abstract
The incidence of pancreatic duct stones (PDS) is less than 1%. After the formation of stones, the lumen of the pancreatic duct is blocked, and the pancreatic juice cannot be discharged smoothly, resulting in the impairment of the internal and external secretions of the pancreas. Several national guidelines now recommend endoscopic retrograde cholangiopancreatography (ERCP) as the treatment for PDS. The emergence of SpyGlass makes it possible to visualize the ERCP blind area of the pancreatic system directly. Electrohydraulic lithotripsy (EHL) under SpyGlass can crush large and pressure-resistant stones into smaller fragments, significantly improving the success of the endoscopic treatment of large stones. Here, we report a patient presented with acute alcohol-associated pancreatitis, found to have PDS on imaging, who underwent ERCP combined with SpyGlass (EHL), avoiding surgery, reducing trauma, and being discharged from the hospital with a rapid recovery. Therefore, endoscopic therapy is effective and safe for PDS patients. The combination therapy of this patient is the first use of SpyGlass for PDS in our centre, which marks a new stage in the application of endoscopic therapy for pancreatic diseases.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the technique of choice for the treatment of biliopancreatic pathology. However, fluoroscopic imaging does not always allow an adequate diagnosis. On the other hand, some large stones cannot be removed by the usual methods. In these situations, cholangioscopy has proven to be an essential tool for the diagnosis of biliary strictures and the treatment of large stones. Its role in pancreatic pathology is also increasing. The development of a single-operator, disposable cholangioscope has made it possible to expand the technique to a large number of hospitals that perform ERCP. For this reason, the Spanish Society of Digestive Endoscopy has developed this consensus document on the use of the Spyglass-DS cholangioscope. The document has been prepared by a group of endoscopists with expertise in cholangioscopy, reviewing the scientific evidence on the main current indications for cholangiopancreatoscopy.

Abstract
BACKGROUND Selective cannulation and stenting of complex, tight, and/or angulated biliary strictures under endoscopic retrograde cholangiopancreaticography (ERCP) can be challenging. Digital single-operator cholangioscopy (SOC) may facilitate guidewire advancement through the stricture with endoscopic visual guidance. We aimed to describe a case series on clinical outcomes of this technique for selective cannulation, when used after failed conventional ERCP attempts. METHODS Consecutive patients who underwent therapeutic digital SOC for selective cannulation of biliary strictures after failed conventional ERCP were retrospectively included. RESULTS Ten patients with a malignant (n = 6) or benign (n = 4) biliary stricture were included. Digital SOC-assisted selective guidewire insertion and stent placement across the biliary stricture were technically successful in five (50%) patients. Bilirubin levels improved in all patients with technical success. One (10%) patient developed a post-ERCP pancreatitis. CONCLUSIONS Technically successful cannulation of biliary strictures with digital SOC was achieved in half of patients in whom cannulation with conventional ERCP failed, sparing them more invasive interventions. Stricture opacification during the failed ERCP was seen in all technically successful SOCs.

Abstract
Primary cystic duct carcinoma is a rare tumor. The curative treatment of cystic duct carcinoma is complete surgical resection, for which the evaluation of local extension is important. We herein report two cases of cystic duct carcinoma in which a preoperative examination was performed using per-oral cholangioscopy (POCS). Both patients underwent POCS due to suspicion of cystic duct carcinoma based on imaging findings. A visual analysis and biopsy were performed to evaluate local extension, which led to surgery. These cases suggest that POCS is useful for the preoperative assessment of local extension in advanced cystic duct carcinoma.

Abstract
PURPOSE OF REVIEW To summarize the current status and future perspectives of the endoscopic management of biliary strictures. RECENT FINDINGS In addition to conventional diagnostic modalities, such as cross-sectional imaging and endoscopic ultrasonography (EUS), per-oral cholangioscopy is helpful for indeterminate biliary strictures. It allows direct visualization of the biliary tract and targeted biopsy. For distal malignant biliary obstruction (MBO), a self-expandable metal stent (SEMS) via endoscopic retrograde cholangiopancreatography (ERCP) is a standard of care. EUS-guided biliary drainage (EUS-BD) is an emerging alternative to percutaneous transhepatic biliary drainage in cases with failed ERCP. EUS-BD is also an effective salvage option for perihilar MBO, which can not be managed via ERCP or percutaneous transhepatic biliary drainage. Preoperative drainage is necessary for most jaundiced patients as neoadjuvant chemotherapy is widely administered for resectable and borderline resectable pancreatic cancer, and a SEMS is preferred in this setting, too. For benign biliary strictures, a covered SEMS can improve stricture resolution and reduce the number of endoscopic sessions as compared to plastic stents. SUMMARY ERCP and EUS play a central role in the diagnosis and drainage for both malignant and benign biliary strictures.

Use of Endoscopic Scraper and Cell Block Technique as a Replacement for Conventional Brush for Diagnosing Malignant Biliary Strictures. Cancers (Basel) 2022; 14:cancers14174147.

Abstract
Histological evidence is essential for diagnosing malignant biliary strictures. However, conventional brush cytology remains the primary method used worldwide, despite its low diagnostic sensitivity and accuracy, as it is technically easy, rapid, and cost-effective. The aim of this study was to evaluate the diagnostic performance of a recently introduced endoscopic scraper, the simplicity of which is comparable to that of a conventional brush, by comparing diagnostic yields and the number of collected cells. The sensitivity of the endoscopic scraper when using the cell block technique was significantly higher than when using brush cytology or a brush with the cell block technique (53.6% vs. 30.9%, p < 0.001; 53.6% vs. 31.6%, p = 0.024, respectively). Quantitative digital image analysis of cell block sections revealed that the median number of cells obtained with the endoscopic scraper was significantly higher than when using the brush (1917 vs. 1014 cells, p = 0.042). Furthermore, seven cases (8.3%; 7/84) were diagnosed by immunohistochemical analysis of the cell block section obtained from the endoscopic scraper. Given its simplicity and greater capacity for sample acquisition, use of the endoscopic scraper in conjunction with the cell block technique could replace brush cytology for the histological diagnosis of malignant biliary strictures.

Abstract
BACKGROUND Patients with primary sclerosing cholangitis (PSC) are at a high risk of developing cholestatic liver disease and biliary cancer, and endoscopy is crucial for the complex management of these patients.
AIM To clarify the utility of recently introduced digital single-operator video cholangioscopy (SOVC) for the endoscopic management of PSC patients.
METHODS In this observational study, all patients with a history of PSC and in whom digital SOVC (using the SpyGlass DS System) was performed between 2015 and 2019 were included and retrospectively analysed. Examinations were performed at a tertiary referral centre in Germany. In total, 46 SOVCs performed in 38 patients with a history of PSC were identified. The primary endpoint was the evaluation of dominant biliary strictures using digital SOVC, and the secondary endpoints were the performance of selective guidewire passage across biliary strictures and the diagnosis and treatment of biliary stone disease in PSC patients.
RESULTS The 22 of 38 patients had a dominant biliary stricture (57.9%). In 4 of these 22 patients, a cholangiocellular carcinoma was diagnosed within the stricture (18.2%). Diagnostic evaluation of dominant biliary strictures using optical signs showed a sensitivity of 75% and a specificity of 94.4% to detect malignant strictures, whereas SOVC-guided biopsies to gain tissue for histopathological analysis showed a sensitivity of 50% and a specificity of 100%. In 13% of examinations, SOVC was helpful for guidewire passage across biliary strictures that could not be passed by conventional methods (technical success rate 100%). Biliary stone disease was observed in 17.4% of examinations; of these, in 37.5% of examinations, biliary stones could only be visualized by SOVC and not by standard fluoroscopy. Biliary stone treatment was successful in all cases (100%); 25% required SOVC-assisted electrohydraulic lithotripsy. Complications, such as postinterventional cholangitis and pancreatitis, occurred in 13% of examinations; however, no procedure-associated mortality occurred.
CONCLUSION Digital SOVC is effective and safe for the endoscopic management of PSC patients and may be regularly considered an additive tool for the complex endoscopic management of these patients.

Abstract
The differential diagnosis between benign and malignant biliary strictures is challenging and requires a multidisciplinary approach with the use of serum biomarkers, imaging techniques, and several modalities of endoscopic or percutaneous tissue sampling. The diagnosis of biliary strictures consists of laboratory markers, and invasive and non-invasive imaging examinations such as computed tomography (CT), contrast-enhanced magnetic resonance cholangiopancreatography, and endoscopic ultrasonography (EUS). Nevertheless, invasive imaging modalities combined with tissue sampling are usually required to confirm the diagnosis of suspected malignant biliary strictures, while pathological diagnosis is mandatory to decide the optimal therapeutic strategy. Although EUS-guided fine-needle aspiration biopsy is currently the standard procedure for tissue sampling of solid pancreatic mass lesions, its diagnostic value in intraductal infiltrating type of cholangiocarcinoma remains limited. Moreover, the "endobiliary approach" using novel slim biopsy forceps, transpapillary and percutaneous cholangioscopy, and intraductal ultrasound-guided biopsy, is gaining ground on traditional endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography endobiliary forceps biopsy. This review focuses on the available endobiliary techniques currently used to perform biliary strictures biopsy, comparing the diagnostic performance of endoscopic and percutaneous approaches.

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
BACKGROUND The use of nonradiation endoscopic retrograde cholangiopancreatography (NR-ERCP) for choledocholithiasis is still limited. Hereby, we introduced our experience of digital cholangioscopy (DCS)-assisted NR-ERCP for retrieval of common bile duct stones. METHODS Altogether, data of 132 patients who underwent DCS-assisted NR-ERCP for choledocholithiasis were collected. Procedure details, complications, and short-term follow-up were reviewed and analyzed and were compared with those of conventional endoscopic retrograde cholangiopancreatography (ERCP). RESULTS Routine stone extraction and laser lithotripsy were planned in 116 and 16 patients, respectively. Biliary access was successfully achieved by standard biliary cannulation and by advanced techniques in 99 and 33 patients, respectively. Complete stone removal was achieved in a single session in all patients. Routine stone extraction was performed in 117 patients, and laser lithotripsy was applied in 15 patients, among whom 14 patients with planned lithotripsy and 1 unexpected impacted stone found during the procedure. Unexpected right localized intrahepatic stones and purulent cholecystitis were found in 1 and 3 patients, respectively. Three mild and 1 moderate pancreatitis, 5 cases of hyperamylasemia, and 2 cases of leukocytosis occurred as complications. Short-term follow-up revealed no stone residual. Procedure details, technical success, and complications were not statistically different than conventional ERCP. CONCLUSIONS DCS-assisted NR-ERCP is technically feasible, efficient, and safe for retrieval of common bile duct stones. This novel method is superior to conventional ERCP on detecting unexpected concomitant biliary diseases.

[PMID: 34326941 PMCID: PMC8311469 DOI: 10.4253/wjge.v13.i7.198] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 05/18/2021] [Accepted: 07/06/2021] [Indexed: 02/06/2023] Open
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.

Diagnostic performance of digital and video cholangioscopes in patients with suspected malignant biliary strictures: a systematic review and meta-analysis. Surg Endosc 2021; 36:2827-2841. [PMID: 34076761 DOI: 10.1007/s00464-021-08571-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 05/18/2021] [Indexed: 01/27/2023]
Abstract
BACKGROUND Per-oral cholangioscopy (POC) has evolved over the past decade from fiberoptic to digital and video imaging systems. Nowadays, only direct per-oral cholangioscopy (DPOC) and digital single-operator cholangioscopy (DS) are performed in daily practice. With better image resolution, POC is increasingly used as diagnostic tools in patients with suspected malignant biliary stricture (MBS). We aimed to evaluate the diagnostic yield of digital/video cholangioscopes for the diagnosis of MBS. METHODS A systematic search was performed in MEDLINE, Embase, and ISI Web of Knowledge databases until April 2020, to identify randomized controlled trials and prospective studies using digital or video POC. The meta-analysis of diagnostic accuracy study was performed to calculate summary estimates of the primary outcomes, including pooled sensitivity, and specificity of POC to diagnose MBS using bivariate random-effects models. Tissue histopathology was used as the reference standard for MBS diagnosis. For benign stricture, negative tissue histopathology and at least 6 months clinical follow-up were required. RESULTS Thirteen original articles with 876 patients were identified. The overall pooled sensitivity and specificity were 88 (95% CI 83-91) and 95 (95% CI 89-98), respectively. The area under the curve (AUROC) was 0.94 (95% CI 0.92-0.96). Subgroup analysis showed that cholangioscopic image impression provided significantly higher sensitivity (93% (95% CI 88-96) vs 82% (95% CI 76-87); p = 0.007), but lower specificity 86% (95% CI 75-92) vs 98 (95% CI 95-99); p < 0.001) than the tissue diagnosis from cholangioscopic-guided biopsy. In addition, biopsy obtained from DPOC had significantly higher sensitivity than that of DS (92% (95% CI 81-97) vs 79% (95% CI 72-84); p = 0.004). Diagnostic performance under image-enhanced endoscopy was not significantly better from white light endoscopy. CONCLUSIONS Digital/video POC has very high diagnostic performance to diagnose MBS. While image diagnosis provides higher sensitivity than biopsy, its specificity drops as a trade-off.

Abstract
Endoscopic management of bile duct stones is now the standard of care, but challenges remain with difficult bile duct stones. There are some known factors associated with technically difficult bile duct stones, such as large size and surgically altered anatomy. Endoscopic mechanical lithotripsy is now the standard technique used to remove large bile duct stones, but the efficacy of endoscopic papillary large balloon dilatation (EPLBD) and cholangioscopy with intraductal lithotripsy has been increasingly reported. In patients with surgically altered anatomy, biliary access before stone removal can be technically difficult. Endotherapy using two new endoscopes is now utilized in clinical practice: enteroscopy-assisted endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-guided antegrade treatment. These new approaches can be combined with EPLBD and/or cholangioscopy to remove large bile duct stones from patients with surgically altered anatomy. Since various endoscopic procedures are now available, endoscopists should learn the indications, advantages and disadvantages of each technique for better management of bile duct stones.

Clinical Outcomes of Digital Cholangioscopy-Guided Procedures for the Diagnosis of Biliary Strictures and Treatment of Difficult Bile Duct Stones: A Single-Center Large Cohort Study. J Clin Med 2021; 10:jcm10081638. [PMID: 33921514 PMCID: PMC8069886 DOI: 10.3390/jcm10081638] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 04/02/2021] [Accepted: 04/05/2021] [Indexed: 12/12/2022] Open
Abstract
Although Spy DS (SpyGlass DS Direct Visualization System) is considered to be useful for the diagnosis of bile duct strictures and the treatment of bile duct stones, there is limited data to date validating its efficacy. We hence retrospectively evaluated the clinical outcomes of the use of Spy DS in a large number of patients. A total of 183 patients who underwent Spy DS-guided procedures for indeterminate bile duct strictures (n = 93) and bile duct stones (n = 90) were analyzed retrospectively. All patients (93/93) with bile duct strictures successfully underwent visual observation, and 95.7% (89/93) of these patients successfully underwent direct biopsy. The sensitivity, specificity, and overall accuracy were 94.7%, 83.3%, and 90.3%, respectively, for visual impression; 80.9%, 100%, and 89.2%, respectively, for histopathological analysis of a direct biopsy; and 96.5%, 91.7%, and 94.6%, respectively, for visual impression combined with biopsy. Successful visualization of the stones was achieved in 98.9% (89/90) of the patients, and complete stone removal was achieved in 92.2% (83/90) of the patients, with an average of 3.3 procedures. The adverse events rate was 17.5% (32/183; cholangitis in 15 patients, fever the following day in 25, pancreatitis in 1, hemorrhage in 1, and gastrointestinal perforation in 1). No administration of antibiotics before the procedure was found to be a statistically significant risk factor for the development of fever after the procedure (p < 0.01). Spy DS-guided procedures are effective for the diagnosis and treatment of bile duct lesions and can be performed with a low risk of serious adverse events.

Abstract
The diagnostic process for biliary strictures remains challenging in some cases. A broad differential diagnosis exists for indeterminate biliary strictures, including benign or malignant lesions. The diagnosis of indeterminate biliary strictures requires a combination of physical examination, laboratory testing, imaging modalities, and endoscopic procedures. Despite the progress of less invasive imaging modalities such as transabdominal ultrasonography, computed tomography, and magnetic resonance imaging, endoscopy plays an essential role in the accurate diagnosis, including the histological diagnosis. Imaging findings and brush cytology and/or forceps biopsy under fluoroscopic guidance with endoscopic retrograde cholangiopancreatography (ERCP) are widely used as the gold standard for the diagnosis of biliary strictures. However, ERCP cannot provide an intraluminal view of the biliary lesion, and its outcomes are not satisfactory. Recently, peroral cholangioscopy, confocal laser endomicroscopy, endoscopic ultrasound (EUS), and EUS-guided fine-needle aspiration have been reported as useful for indeterminate biliary strictures. Appropriate endoscopic modalities need to be selected according to the patient's condition, the lesion, and the expertise of the endoscopist. The aim of this review article is to discuss the diagnostic process for indeterminate biliary strictures using endoscopy.

Abstract
The most effective and the standard treatment for bile duct stones (BDSs) is endoscopic retrograde cholangiopancreatography (ERCP). However, in 10% to 15% of patients with BDSs, the stones cannot be removed by conventional ERCP, which involves endoscopic sphincterotomy followed by balloon or basket extraction. Additional techniques or devices are often necessary to remove these difficult bileduct stones, including endoscopic papillary large balloon dilatation to make a larger papillary opening and/or mechanical lithotripsy to fragment the stones. Advances in cholangioscopy have made possible electrohydraulic or laser lithotripsy under direct cholangioscopic visualization during ERCP. Cholangioscopy-guided lithotripsy could be another good option in the armamentarium of techniques for removing difficult BDSs. Here we review endoscopic techniques based on single-operator cholangioscopy for the management of difficult BDSs.

Abstract
BACKGROUND Laparoscopic common bile duct exploration (LCBDE) has gained wide popularity for the treatment of choledocholithiasis. However, it remains unclear whether LCBDE is a better alternative option for the patients with difficult biliary stones. Thus, the aim of the present study was to explore the safety and efficacy of LCBDE for these patients by retrospectively analyzing our data and combing with literature review. METHODS Between September 2011 and February 2019, 1064 consecutive patients who underwent LCBDE at Shanghai Tenth People's Hospital were reviewed. The clinical data of patients with difficult biliary stones were selected and retrospectively analyzed. RESULTS Of these patients, 334 cases were confirmed with difficult biliary stones, and the overall complete stone clearance rate was 98.8% (330/334). 34 cases (10.2%) were performed with laser lithotripsy. A total of 296 patients (88.6%) underwent primary closure of common bile duct, and T-tube drainage was indwelled in 38 patients (11.4%). No bile duct injury, bleeding, perforation and surgery-related deaths were observed. The overall morbidity rate was 6.6%. 16 cases (4.8%) occurred in bile leakage with primary closure procedure, and all of them were managed successfully with conservative therapy. The median follow-up period was 9 months with stone recurrence occurring in 9 patients (2.7%). There was no evidence of bile duct stricture in all cases. CONCLUSIONS The current study suggests that LCBED is a considerable safe and effective option for the patients with difficult biliary stones. A randomized clinical trial is needed to further evaluate the benefit of LCBDE in this subgroup.

Abstract
Background Cholangiocarcinomas are relatively rare tumors most frequently arising from the epithelium of the hilar bile ducts. The diagnosis is often made in advanced (symptomatic) stages, which accounts for the infavorable prognosis with a 5-year survival of less than 10%. Identification of perihilar cholangiocarcinoma (pCCA) is often challenging because there is no single method offering sufficient diagnostic accuracy. Summary Most tumors arise in patients without specific risk factors. Clinical symptoms of pCCA are nonspecific and reliable biomarkers are lacking, with carbohydrate antigen 19-9 being the most commonly used tumor marker (but with a low accuracy). Cross-sectional imaging (CT and MRI) is used to identify and map hilar strictures and determine resectability by showing vascular involvement. Endoscopic ultrasound offers additional information on locoregional tumor spread and lymph node involvement. Endoscopic retrograde cholangiography in combination with cholangioscopy gives direct access to and imaging of hilar strictures but it does not always distinguish between pCCA and benign hilar strictures. Tissue acquisition for histological diagnosis is challenging, with frequent sampling errors regardless of the method of biopsy procurement because of the cellular paucity of tumor tissue. Key Messages In suspected perihilar malignancy, a mosaic of clinical data has to be taken into account. Histological evaluation of (endoscopically harvested) specimens is pivotal to differential diagnosis. Several new techniques to increase diagnostic accuracy are under investigation (biomarkers and genetic testing among others).

Abstract
Background The accurate diagnosis of biliary strictures remains problematic. The aim of the present study was to prospectively evaluate the clinical utility of probe-based confocal laser endomicroscopy (pCLE) under the direct view of peroral cholangioscopy (POCS) for the diagnosis of biliary strictures. Methods Consecutive patients with biliary strictures were included. We investigated sensitivity, specificity, and accuracy to diagnose malignancy for (1) ERCP alone, (2) POCS, (3) pCLE under the direct view of POCS, and (4) tissue sampling under the direct view of POCS. Results A total of 30 patients (17 with malignant lesions) were prospectively enrolled. (1) ERCP alone showed 88.2% sensitivity, 46.2% specificity, and 70% (95% confidence interval (CI), 52.1%–83.3%) accuracy. (2) POCS showed 100% sensitivity, 76.9% specificity, and 90% (95% CI, 74.4%–96.5%) accuracy. (3) pCLE under the direct view of POCS showed 94.1% sensitivity, 92.3% specificity, and 93.3% (95% CI, 78.7%–98.8%) accuracy. (4) Tissue sampling under the direct view of POCS showed 82.4% sensitivity, 100% specificity, and 90% (95% CI, 74.4%–96.5%) accuracy. Conclusions pCLE under the direct view of POCS provided highly accurate and sensitive characterization of biliary strictures and showed the potential for more diagnostic reliability and reduction of delays in diagnosis. This trial was registered at UMIN (registration number: UMIN000033801).

Abstract
PURPOSE OF REVIEW Indeterminate biliary strictures (IDBS) continue to be an area of frustration for clinicians. Standard endoscopic retrograde cholangiopancreatography (ERCP) with conventional brush cytology and/or forceps biopsy has a low sensitivity for distinguishing benign from malignant biliary strictures. A delay in diagnosis of malignancy has consequences for subsequent therapy or surgery. In this article, we review current and emerging technologies that may aid in this diagnostic dilemma. RECENT FINDINGS Several technologies have been utilized in IDBS to establish a diagnosis which include peroral cholangioscopy, confocal laser endomicroscopy, endoscopic ultrasound with fine needle aspiration, intraductal ultrasound, optical coherence tomography, fluorescence in situ hybridization, next generation sequencing, integrated molecular pathology, and DNA-image cytometry. While cholangioscopy and confocal laser endomicroscopy have become standards of care in expert centers for the evaluation of patients with IDBS, there are several endoscopic and molecular modalities that may also aid in establishing a diagnosis. Further head-to-head prospective diagnostic studies as well as cost-efficacy studies are needed.

Abstract
BACKGROUND Biliary strictures are frequently encountered in clinical practice. The determination of their nature is often difficult. This study aims to systematically evaluate the efficacy and safety of the second generation of digital single-operator cholangioscopy (SpyGlass DS, DSOC) in indeterminate biliary strictures (IBDS) through biopsies. METHODS All relative studies published in Medline, the Cochrane Library, Web of Science, and EMBASE were included. The diagnostic tests for IBDS were compared to the surgical histology, autopsy, or long-term clinical follow-up. The methodological quality of the included studies was evaluated by the Quality Assessment of Studies of Diagnostic Accuracy Included in Systematic Reviews (QUADAS-2). RESULTS A total of 11 studies, which involved 356 patients diagnosed through biopsies, were included. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were 0.74 (95% CI: 0.67-0.80), 0.98 (95% CI: 0.95-1.00), 10.52 (95% CI: 5.45-20.32), 0.31 (95% CI: 0.23-0.41), and 65.18 (95% CI: 26.79-158.61), respectively. The area under the curve (AUC) was 0.9479, and the pooled adverse event rate was 7%. The sensitivity and specificity in the heterogeneity analysis were I2 = 48.1% and I2 = 25.4%, respectively. CONCLUSION SpyGlass DS is a safe and effective technique for IBDS. However, future randomized trials are needed to determine optimal number of biopsies.

Abstract
Background and Aims Pancreaticobiliary stone extraction during endoscopic retrograde cholangiopancreatography can be challenging when working space is limited or the duct is irregular and strictured. We aimed to demonstrate several difficult anatomic scenarios in which stone extraction was accomplished by ductoscopic grasping and retrieval using miniature devices. Methods In 2 cases, a miniature retrieval basket and snare are used during cholangioscopy to grasp refractory stones in the intrahepatic and cystic ducts, respectively. In cases 3 and 4, a miniature basket and snare are used during pancreatoscopy to facilitate stone extraction from stenotic and tortuous pancreatic ducts. In case 5, a miniature forceps is used to extract a stone from within a dilated pancreatic side branch. Results Stone extraction was successful in all cases without adverse events. Conclusions Miniature grasping accessories that fit through the working channel of the cholangioscope/pancreatoscope may allow stone retrieval in difficult anatomic scenarios and thus represent a meaningful addition to our therapeutic armamentarium for the treatment of this condition.

Abstract
Background and study aims Digital, per-oral cholangioscopy (POCS) allows diagnosis of biliary ducts disorders and treatment for complicated stones. We aimed to determine the diagnostic accuracy of digital POCS systems for stricture lesions and the factors precluding complete biliary stone clearance. Patients and methods We performed a retrospective analysis of a prospective database of 265 consecutive patients referred for POCS between December 2016 and July 2018. We first analyzed the diagnostic accuracy of digital POCS for malignant and benign stricture lesions in 147 patients. Then, we analyzed the factors associated with complete or partial biliary stone clearance achieved with electrohydraulic lithotripsy (EHL) delivered via POCS in 118 patients. Results In the diagnostic group, digital POCS achieved 91 % visual-impression sensitivity, 99 % specificity, 99 % positive and 91 % negative predictive values, and 63.64 positive and 0.09 negative likelihood ratios for malignancy diagnosis. In the therapeutic group, complete biliary stone clearance was achieved by EHL in 94.9 % patients; the mean stone size was 20 mm (10-40 mm). In multivariable analyses, a stone size > 20 mm (OR: 1.020, P < 0.001) and the number of stones ≥ 3 (OR: 1.276, P < 001) was associated with partial biliary stone clearance. Adverse events were reported in 3.3 % patients; no deaths were reported 30 days after the procedure. Conclusions Digital POCS has excellent diagnostic efficacy for biliary lesions. EHL via POCS is effective for complicated biliary stone clearance. Stone size (> 20 mm) and the number of stones (≥ 3) are associated with partial biliary stone clearance.

Abstract
Distal biliary strictures (DBS) are common and may be caused by both malignant and benign pathologies. While endoscopic procedures play a major role in their management, a comprehensive review of the subject is still lacking. Our consensus statements were formulated by a group of expert Asian pancreatico-biliary interventional endoscopists, following a proposal from the Digestive Endoscopy Society of Taiwan, the Thai Association for Gastrointestinal Endoscopy, and the Tokyo Conference of Asian Pancreato-biliary Interventional Endoscopy. Based on a literature review utilizing Medline, Cochrane library, and Embase databases, a total of 19 consensus statements on DBS were made on diagnosis, endoscopic drainage, benign biliary stricture, malignant biliary stricture, and management of recurrent biliary obstruction and other complications. Our consensus statements provide comprehensive guidance for the endoscopic management of DBS.

Abstract
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an algorithm that can facilitate management decisions in these patients.

Abstract
Cholangioscopy provides an opportunity to directly visualize the bile duct for diagnosing biliary lesions and for therapeutic interventions. Although there are different cholangioscopy techniques available, single-operator cholangioscopy has gained widespread acceptance as the standard technique for interventions in the biliary system because of its ease of use and widespread availability. Single-operator cholangioscopy can be used for both diagnostic and therapeutic indications in the biliary tract. Diagnostic cholangioscopy is used for direct evaluation of indeterminate bile duct strictures with biopsies, diagnosing filling defects in the bile ducts observed during endoscopic retrograde cholangiography (ERC) imaging, preoperative mapping of the precise location and extension of tumors of the biliary tract, and diagnosis of intraductal neoplasms. Therapeutic cholangioscopy is used for visually guided treatment of biliary stones that have failed extraction with conventional ERC techniques, residual or impacted stones by using intraductal lithotripsy, ablation of biliary tumors and for facilitation of guidewire advancement into selective intrahepatic ducts for adequate biliary drainage. In this review, we will focus on advances in the single-operator cholangioscopy techniques in the diagnosis and management of biliary disorders.

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
Aims: Endoscopic management of indeterminate strictures and complex stones remains a challenge, for which the latest generation single-operator digital cholangioscope (SpyGlass DS) has shown promising results. We aimed to study the clinical impact of single-operator digital cholangioscope at our tertiary academic center. Methods: We retrospectively reviewed all digital cholangioscopies performed from June 2015 to May 2018. Patient characteristics, procedure characteristics, and post-procedural patient outcomes were recorded. Results: A total of 50 patients (26 men, average age 61.4 years) underwent 67 procedures. Indications were biliary stones (21/50, 42%), strictures and primary sclerosing cholangitis surveillance (22/50, 46%), and miscellaneous (7/50, 14%). The average procedure time was 82 ± 29 min (99.5 min for stones and 74.2 min for strictures). Stone clearance was achieved in 19/21 (90.47%) cases, with electrohydraulic lithotripsy employed in 16/21 and repeat cholangioscopy necessary in 9/21. Malignant strictures (10) were differentiated from benign (12) in all cases both in patients with primary sclerosing cholangitis (9) and in those without (13), based on visual cholangioscopic features (sensitivity and specificity 100%), single-operator digital cholangioscope–directed biopsies (sensitivity 60% and specificity 100%), and brush cytology (sensitivity 37.5% and specificity 100%). Complications included one post-sphincterotomy bleeding and one post-procedural cholangitis despite antibiotic prophylaxis, but no procedure-related mortality. Conclusion: Single-operator digital cholangioscope had a high success rate and a low rate of complications for management of indeterminate strictures and difficult biliary stones. Visual cholangioscopic features of biliary strictures had excellent diagnostic accuracy, and targeted biopsies outperformed brush cytology. Early implementation of cholangioscopy for select indications leads to successful patient outcomes and reduces diagnostic delays, cost, and risks of repeat endoscopic retrograde cholangiopancreatographies.

Abstract
BACKGROUND AND AIM This study aims to assess the clinical validity and safety of single-operator cholangioscopy system (SOCS) for the treatment of concomitant gallbladder stones and secondary common bile duct (CBD) stones. METHODS This retrospective study included 10 consecutive patients who had small-sized stones (< 1 cm) in both the gallbladder and CBD; the patients underwent SOCS treatment from June 2016 to December 2016. The clinical validity of this minimally invasive surgery was determined by the operation success rate, stone removal rate, postoperative hospital stay, hospitalization cost, and contrast images before and after the operation. The clinical safety was evaluated by perioperative complications and outcomes, gallbladder stone recurrence, and gallbladder contractility function. RESULTS Both the technique success rate and the stone removal rate when using SOCS was 100%. There were no serious complications that occurred during the operation; three patients developed acute cholecystitis, and four patients underwent hyperamylasemia after the surgery. The average postoperative hospital stay was 5.8 ± 1.32 days, and the average hospitalization cost was 7466 ± 566.1 dollars. In the follow-up period, which ranged from 3 to 8 months, there was no stone residuals or recurrences in the gallbladder and CBD, and no patient showed a recurrence of biliary colic. In addition, the gallbladder contractility function was proven to be normal within 3 to 6 months after the operation. CONCLUSIONS SOCS could successfully manage concomitant gallbladder stones and secondary CBD stones and precisely protect normal biliary function.

Abstract
BACKGROUND Recently, a digital single-operator cholangiopancreatoscope (DSOC) has become available. This system allows the performance of electrohydraulic lithotripsy (EHL) even within the main pancreatic duct (MPD). However, there are only few reports of EHL for MPD stones using SPY-DS. AIMS The aim of this study was to evaluate the technical feasibility and efficacy of EHL for MPD stones under DSOC guidance. METHODS Between October 2016 and August 2017, patients with MPD stones were retrospectively enrolled in this study. The presence of MPD stones was diagnosed by endoscopic ultrasound and MRCP. The patients' baseline characteristics and those of the stones, including their size, number, and site in the MPD, number of EHL procedures, and adverse events, were reviewed. RESULTS A total of 21 patients were retrospectively enrolled. The etiologies of chronic pancreatitis were idiopathic (n = 4) and alcohol induced (n = 17). The pancreatic stone was variously located in the head (n = 6), body (n = 11), tail (n = 1), head and body (n = 2), and body and tail (n = 1) of the pancreas. Median pancreatic stone size was 12 mm, and the mean number of ERCP sessions was 1.29 (range 1-3). EHL was successfully performed in 15 patients (85.7%, 18/21), and the rate of complete stone clearance was 88.2% (18/21). Severe adverse events were not seen in any of the patients, although one patient developed mild acute pancreatitis. CONCLUSIONS In conclusion, although additional case reports and prospective studies are needed, EHL under DSOC may be an option to treat MPD stones.

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.

Comparison of digital versus fiberoptic cholangioscopy in patients requiring evaluation of bile duct disease or treatment of biliary stones. Ann Gastroenterol 2019; 32:199-204. [PMID: 30837794 PMCID: PMC6394257 DOI: 10.20524/aog.2019.0358] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Accepted: 01/09/2019] [Indexed: 02/07/2023] Open
Abstract
Background Recently, the introduction of the novel digital SpyGlass™ DS Direct Visualization system (Boston Scientific Corp., Natick, MA, USA) has signaled the transition into the era of digital single-operator cholangioscopy (D-SOC). We sought to compare the clinical utility between fiberoptic single-operator cholangioscopy (F-SOC) and D-SOC in a tertiary-care referral center in Greece. Methods This was a retrospective analysis of a prospective database of single-operator cholangioscopy (SOC) procedures performed over an 8-year period (2009-2017) at a single tertiary-care referral center. The study population consisted of consecutive adults referred for cholangioscopy for a variety of clinical indications, including biliary strictures, difficult biliary stones and migrated or occluded pancreatic or biliary stents. Results A total of 2763 endoscopic retrograde cholangiopancreatography procedures were performed during the study period. Overall, SOC was performed in 68 (2.46%) procedures (F-SOC=39, D-SOC=29), showing a significant increase in the utilization of cholangioscopy during the D-SOC (29/599; 4.84%) compared with the F-SOC (39/2124; 1.83%) period (P=0.0001). The overall technical success of diagnostic SOC was 69.1% (38/55), being marginally higher for D-SOC (83.3%) than for F-SOC (58.1%), although not reaching statistical significance (P=0.07). Conclusions D-SOC was utilized more frequently in our tertiary-care non-academic referral center, demonstrating a favorable safety profile and a trend towards a marginally higher technical success rate for the diagnosis of biliary strictures compared with F-SOC.
