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.

Efficacy and safety of a single-use cholangioscope for percutaneous transhepatic cholangioscopy. Endosc Int Open 2024; 12:E981-E988. [PMID: 39184059 PMCID: PMC11343621 DOI: 10.1055/a-2366-2265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 07/10/2024] [Indexed: 08/27/2024] Open
Abstract
Background and study aims Percutaneous transhepatic cholangioscopy (PTCS) is a management option for patients in whom peroral cholangioscopy or endoscopic retrograde cholangiopancreatography (ERCP) fail. We conducted a case series on the efficacy and safety of PTCS using a cholangiopancreatoscope cleared by the US Food and Drug Administration in 2020. Patients and methods Fifty adult patients scheduled for PTCS or other cholangioscopic procedure were enrolled at seven academic medical centers and followed for 30 days after the index procedure. The primary efficacy endpoint was achievement of clinical intent by 30 days after the index PTCS procedure. Secondary endpoints included technical success, procedure time, endoscopist ratings of device attributes on a scale of 1 to 10 (best), and serious adverse events (SAEs) related to the device or procedure. Results Patients had a mean age of 64.7±15.9 years, and 60.0% (30/50) were male. Forty-four patients (88.0%) achieved clinical intent by 30 days post-procedure. The most common reasons for the percutaneous approach were past (38.0%) or anticipated (30.0%) failed ERCP. The technical success rate was 96.0% (48/50), with a mean procedure time of 37.6 minutes (SD, 25.1; range 5.0-125.0). The endoscopist rated the overall ability of the cholangioscope to complete the procedure as a mean 9.2 (SD, 1.6; range 1.0-10.0). Two patients (4.0%) experienced related SAEs, one of whom had a fatal periprocedure aspiration. Conclusions PTCS is an important endoscopic option for selected patients with impossible retrograde access or in whom ERCP fails. Because of the associated risk, this technique should be practiced by highly trained endoscopists at high-volume centers. (ClinicalTrials.gov number, NCT04580940).

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
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
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.

Abstract
BACKGROUND While the fiberoptic single-operator cholangiopancreatoscopy (FSOCP) system has demonstrated efficacy in the diagnosis and management of pancreaticobiliary diseases, the digital SOCP (DSOCP) appears to provide higher resolution digital imaging, however a comparison of these devices has not been established. The aim of this work was to compare the efficacy of FSOCP and DSOCP in biliary stone disease and indeterminate biliary strictures. METHODS A retrospective analysis of a prospective cohort was performed in patients undergoing FSOCP or DSOCP demographics included indication, diagnostic yield, procedure time, radiation dose, and complications. RESULTS 324 patients underwent cholangioscopy. FSOCP and DSOCP were utilized in 198 and 126 patients respectively. Male/female ratio was similar and mean age was 66 ± 13 years. Indications included stone disease, indeterminate stricture evaluation and "other" were 47%, 42% and 11% respectively. Mean procedure time for stone disease and the amount of radiation doses in DSOCP group were lower than the FSOCP group (P = 0.032 and P = 0.02, respectively). Diagnostic yield in indeterminate strictures was higher 78% with DSOCP system compared to 37% with FSOCP system (P = 0.004). Complication were low and similar between the groups. CONCLUSIONS DSOCP system provides enhanced diagnostic yield, shorter procedure times and less radiation exposure compared to FSOCP system.

Abstract
BACKGROUND AND AIM Recently, the digital single-operator cholangioscope (SPY-DS) has become available. This system may allow diagnosis by direct visualization and allow performance of various therapeutic procedures. The aim of the present study was to prospectively evaluate the clinical utility of DSOCS for diagnostic and therapeutic procedures for biliary disease. METHODS Technical success was defined as successful visualization of target lesions in the biliary tract and carrying out forceps biopsy as a diagnostic procedure, and successfully carrying out treatment such as guidewire insertion for the area of interest, electrohydraulic lithotripsy (EHL), or migrated stent removal. Also, the present study aimed at investigating diagnostic yield of the cholangioscopic findings and biopsy specimens. RESULTS A total of 55 consecutive patients were prospectively enrolled in this study; a diagnostic procedure was done in 33 patients, and a therapeutic procedure was done in 22 patients. Overall accuracy of visual findings was 93%, with a sensitivity of 83%, a specificity of 89%, positive predictive value (PPV) of 83%, and negative predictive value (NPV) of 100%. However, the overall accuracy of forceps biopsy was 89%, with a sensitivity, specificity, and PPV of 100%, and NPV of 90%. Overall technical success rate of therapeutic procedures such as selective guidewire insertion, EHL or migrated stent removal was 91% (20/22). Finally, adverse events were seen in two cases in the diagnostic group, but were not seen in the therapeutic group. CONCLUSION Although additional cases and a randomized, controlled study with another cholangioscope are needed, diagnostic and therapeutic procedures using SPY-DS appear to be feasible and safe.

Abstract
Recently, the novel SpyGlass DS Direct Visualization system (SPY DS) has become available. This system offers several advantages over the conventional SPYGlass system. This study evaluated the clinical feasibility and efficacy of diagnostic and therapeutic procedures for biliary disorder using SPY DS.In this retrospective study, consecutive patients who had biliary disorder were enrolled between November 2015 and February 2016. All patients could not be diagnosed or treated by standard endoscopic retrograde cholangiopancreatography in our hospital or at another hospital.A total of 28 consecutive patients (21 men and 7 women; median age, 73 years; age range, 55-87 years) were retrospectively enrolled in this study. Among them, diagnostic procedure was performed in 20 patients, and 8 patients underwent therapeutic procedures. The technical success rate for diagnostic procedures was 100% (20/20). Diagnostic accuracy was 100% (19/19). The technical success rate for therapeutic procedures was 88% (7/8). Among these 8 patients, 4 patients with common bile duct stones underwent electrohydraulic lithotripsy. One patient successfully underwent guidewire insertion to remove a migrated plastic stent. The 3 remaining patients underwent SPY DS to insert a guidewire for left bile duct obstruction and for posterior bile duct branch. In the patient who underwent guidewire insertion for left hepatic bile duct obstruction cause by primary sclerosing cholangitis, we could not advance the guidewire into the left hepatic bile duct. No adverse events were seen. Median SPY DS insertion time was 21 min (range, 8-32 min).Single-operator cholangioscopy using SPY DS was feasible and had a marked clinical impact in patients with biliary disease. Additional case reports and prospective studies are needed to examine further applications of this system.

JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2016; 23:E25-E29.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the gold-standard modality for diagnosis and therapy of bilio-pancreatic disease. In particular, peroral cholangiography (POCS) is a useful modality not only for diagnosing biliary disease, but also for therapeutic procedures such as electrohydraulic lithotripsy. The SPY-DS single-operator cholangioscope has recently become available, and offers favorable visualization, a wide view, suction function and a larger accessory working channel. However, if the duodenoscope cannot be advanced into the ampulla of Vater for reasons such as surgical anatomy, POCS cannot be performed. On the other hand, percutaneous transhepatic cholangiodrainage (PTCD) has been developed as an alternative endoscopic ultrasound-guided approach to the biliary tract. Peroral transluminal cholangioscopy (PTLC) using SPY-DS is a novel approach. Because transluminal interventional procedures under endoscopic ultrasound guidance have recently been developed, our technique may have clinical impact for selected cases.

Abstract
Nowadays, cholangioscopy is an established modality in diagnostic and treatment of pancreaticobiliary diseases. The more widespread use and the recent development of new technologies and accessories had renewed the interest of endoscopic visualization of the biliary tract, increasing the range of indications and therapeutic procedures, such as diagnostic of indeterminate biliary strictures, lithotripsy of difficult bile duct stones, ablative techniques for intraductal malignancies, removal of foreign bodies and gallbladder drainage. These endoscopic interventions will probably be the last frontier in the near future. This paper presents the new advances in therapeutic cholangioscopy, focusing on the current clinical applications and on research areas.

Abstract
Endoscopic retrograde cholangiopancreatography is an effective platform for a variety of therapies in the management of benign and malignant disease of the pancreas. Over the last 50 years, endotherapy has evolved into the first-line therapy in the majority of acute and chronic inflammatory diseases of the pancreas. As this field advances, it is important that gastroenterologists maintain an adequate knowledge of procedure indication, maintain sufficient procedure volume to handle complex pancreatic endotherapy, and understand alternate approaches to pancreatic diseases including medical management, therapy guided by endoscopic ultrasonography, and surgical options.
