Efficacy and safety of direct peroral cholangioscopy using a new multibending ultra-slim endoscope for the management of biliary diseases. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2022; 29:1292-1299. [PMID: 35658104 DOI: 10.1002/jhbp.1189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 04/21/2022] [Accepted: 05/01/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND/PURPOSE Compared with currently available duodenoscopy-assisted systems, direct peroral cholangioscopy (DPOC) using an ultra-slim endoscope is limited by technical difficulties. The multibending (MB) ultra-slim endoscope was introduced as a dedicated cholangioscope for DPOC to challenge the technical problem. We retrospectively analyzed the clinical utility of DPOC using an MB endoscope with free-hand insertion into the bile duct in patients with biliary diseases. METHODS A total of 145 patients who underwent DPOC using an MB endoscope were analyzed. The primary outcome was the technical success rate of DPOC using the free-hand insertion of the MB endoscope. The secondary outcomes were the technical success rates of DPOC-guided diagnostic and therapeutic interventions, the diagnostic accuracy of DPOC-guided target biopsy, and adverse events related to DPOC. RESULTS Free-hand biliary insertion of a MB endoscope for DPOC was technically successful in 133 patients (91.7%). DPOC-guided target biopsy was successful in 36 of 38 patients (94.7%) and had a diagnostic accuracy of 91.7% (95% confidence interval, 82.6-100). Sixty-nine therapeutic interventions were performed; technical success was achieved in 65 (94.2%). No severe adverse events were observed. CONCLUSIONS The MB ultra-slim endoscope was technically effective to perform a DPOC including various diagnosis and therapeutic interventions without device assistance. MB endoscope is considered to contribute to expanding a role of DPOC in diagnosis and treatment of diverse biliary tract diseases.

Abstract
Choledochoscopy technology has realized the direct observation of bile duct lesions, and can be loaded with a variety of special accessories to perform the corresponding diagnosis and treatment operations, and has become an important means for the diagnosis of unexplained bile duct stricture and treatment of refractory bile duct stones. With the further enhancement of the imaging quality and operability, the clinical application of choledochoscopy has gradually expanded to the precise positioning of cholangiocarcinoma before surgical resection, the drainage of the gallbladder through the nipple, the removal of the displaced bile duct stent and other fields. This paper briefly reviewed the historical evolution of choledochoscopy and reviewed the latest clinical advances of oral choledochoscopy in the diagnosis and treatment of biliary tract diseases.

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
Mirizzi syndrome is a rare complication of gallbladder disease that can be difficult to treat. In particular, endoscopic treatment often fails because of the inability to access or to capture the impacted cystic duct stone. We report a case of Mirizzi syndrome grade III that was successfully managed by digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage and interval laparoscopic cholecystectomy. Based on our experience, digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage is a feasible minimally invasive approach for the management of high-grade Mirizzi syndrome.

Abstract
Clinical sampling of tissue that is read by a pathologist is currently the gold standard for making a disease diagnosis, but the few minimally invasive techniques available for small duct biopsies have low sensitivity, increasing the likelihood of false negative diagnoses. We propose a novel biopsy device designed to accurately sample tissue in a biliary stricture under fluoroscopy or endoscopic guidance. The device consists of thin blades organized around the circumference of a cylinder that are deployed into a cutting annulus capable of comprehensively sampling tissue from a stricture. A parametric study of the device performance was done using finite element analysis; this includes the blade deployment under combined axial compression and torsion followed by an axial 'cutting' step. The clinical feasibility of the device is determined by considering maximum deployment forces, the radial expansion achieved and the cutting stiffness. We find practical parameters for the device operation to be an overall length of 10 mm and a diameter of 3.5 mm for a [Formula: see text] blade thickness, which allow the device to be safely deployed with a force of 10N and achieve an expansion over 3x its original diameter. A model device was fabricated with these parameters and a [Formula: see text] thickness out of a NiTi superalloy and tested to validate the performance. The device showed strong agreement with an equivalent numerical model, reaching a peak force within 2% of that predicted numerically and fully recovering after compression to 20% of its length. Clinical and Translational Impact Statement -This pre-clinical research conceptually demonstrates a novel expandable device to biopsy tissue in narrow strictures during an ERCP procedure. It can greatly improve diagnostic tissue yield compared to existing methods.

Abstract
Objective Recently, a new digital peroral cholangioscopy (POCS) system, the SpyGlass DS (SpyDS), has been used for POCS-guided lithotripsy for difficult bile duct stones (DBDSs). The aim of this retrospective study was to compare the efficacy of SpyDS-guided electrohydraulic lithotripsy (EHL) for DBDS with that of a conventional digital cholangioscope. Methods Seventeen consecutive patients who had undergone POCS-guided EHL for DBDS with the SpyDS between October 2015 and January 2019 were enrolled in this study group (SpyDS group) using a prospectively maintained database. Fifteen other consecutive patients who had undergone POCS-guided EHL with a conventional digital cholangioscope (CHF-B260) just prior to the introduction of the SpyDS between December 2006 and September 2015 were analyzed as a control group (CHF group). The main outcome measurement was the total procedure time to complete stone removal. Results The rate of complete stone removal was 100% for both groups. The mean total procedure time for the SpyDS group was significantly shorter than that for the CHF group (67±30 minutes vs. 107±64 minutes, p=0.038). The mean number of endoscopic sessions for the SpyDS group was significantly lower than that for the CHF group (1.35±0.49 vs. 2.00±0.85, p=0.037). There were no significant differences in the rate of adverse events between the two groups. Conclusion The SpyDS appears useful for decreasing the procedure time and number of endoscopic sessions for complete stone removal in POCS-guided EHL for DBDS compared with a conventional digital cholangioscope.

Abstract
OBJECTIVE Indeterminate biliary strictures remain a significant diagnostic challenge. Digital single-operator cholangioscopy (D-SOC) incorporates digital imaging which enables higher resolution for better visualization and diagnosis of biliary pathology. We aimed to conduct a systematic review and meta-analysis of available literature in an attempt to determine the efficacy of D-SOC in the visual interpretation of indeterminate biliary strictures. MATERIAL AND METHODS Electronic searches were performed using Medline (PubMed), EMBASE, and Cochrane Library. All D-SOC studies that reported the diagnostic performance in visual interpretation of indeterminate biliary strictures and biliary malignancies were included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 was used to evaluate the quality of the included studies. All data were extracted and pooled to construct a 2 × 2 table. The visual interpretation of D-SOC was compared to resected surgical specimens or clinical follow-up in the included patients. Pooled sensitivity, specificity, positive predictive value, negative predictive value, prevalence, positive likelihood ratio (+LR), negative likelihood ratio (-LR), and diagnostic odds ratio (OR) were calculated. The summarized receiver operating characteristic (SROC) curve corresponding with the area under the curve (AUC) was also analyzed. RESULTS The search yielded 465 citations. Of these, only six studies with a total of 283 procedures met inclusion criteria and were included in the meta-analysis. The overall pooled sensitivity and specificity of D-SOC in the visual interpretation of biliary malignancies was 94% (95% CI 89-97) and 95% (95%CI 90-98), respectively, while +LR, -LR, diagnostic OR, and AUC were 15.20 (95%CI 5.21-44.33), 0.08 (95%CI 0.04-0.14), 308.83 (95%CI 106.46-872.82), and 0.983, respectively. The heterogeneity among 6 included studies was moderate for specificity (I2 = 0.51) and low for sensitivity (I2 = 0.17) and diagnostic OR (I2 = 0.00). CONCLUSION D-SOC is associated with high sensitivity and specificity in the visual interpretation of indeterminate biliary strictures and malignancies. D-SOC should be considered routinely in the diagnostic workup of indeterminate biliary lesions.
