“…Ducts were completely cleared (technical success) in 97.3% of patients and cleared in a single session in 77.4% of patients . The results corroborate previously published studies on D‐SOC in the management of difficult‐to‐treat bile duct stones . The overall success rate of stone removal with D‐SOC appears to be over 95%.…”

“…The D‐SOC could be used in a fluoroscopy/radiation‐free setting to accomplish successful bile duct treatment without the usual exposure to radiation and other disadvantages of the fluoroscopy setting . D‐SOC appears to be superior to SOC with a higher rate of stone clearance in the first procedure (83% vs 58%, P < 0.01) with a shorter procedure time (49 vs 57 min, P = 0.032) . In case of intrahepatic stones, the thinner LL probe is generally preferred to the EHL probe.…”

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.

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.
