Unsuccessful stent replacement in transpapillary biliary drainage with plastic stents (PSs) has a significant impact on patient prognosis; thus, a safe and reliable replacement method is required. We aimed to compare the snare-over-the-guidewire (SOG) method, wherein the PS lumen is used as an access route to the biliary tract and the PS is removed with a snare inserted via the inserted guidewire, with the conventional side-of-stent (SOS) method, wherein the biliary approach is performed from the side of the PS. This retrospective single-center study included 244 consecutive patients who underwent biliary PS replacement between January 2018 and July 2020. The procedural success rates were compared between the two methods. A predictive analysis of unsuccessful PS replacement was also performed. The procedural success rate in the SOG group was significantly higher than that in the SOS group (p = 0.026). In the proximal biliary stenosis lesion, the same trend was observed (p = 0.025). Multivariate analysis also showed that the SOS method (p = 0.0038), the presence of proximal biliary stenosis (p < 0.0001), and parapapillary diverticulum (p = 0.0007) were predictors of unsuccessful PS replacement. The SOG method may be useful for biliary PS replacement, especially in cases of proximal hilar bile duct stenosis.

Abstract Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is one of the IgG4-related systemic sclerosing diseases and responds well to steroid therapy. A 58-year-old male was admitted with hilar bile duct stenosis revealed by computed tomography. We performed percutaneous transhepatic right portal vein embolization (PTPE) and scheduled a right hepatectomy because a hilar cholangiocarcinoma was first suspected. However, there was no cytologic evidence of malignancy and serum IgG4 was elevated. Steroid therapy was initiated after PTPE. There was no evidence of bile duct stenosis after 4 weeks. Improving diagnostic technique, IgG4-SC was diagnosed and treated with steroid therapy. In some cases, we couldn't deny the malignancy and performed unnecessary resection. We recommend that steroid administration while waiting for the liver volume to increase after PTPE is useful. The therapy aids in the diagnosis of bile duct stenosis, which has value for a hilar bile duct limit type of IgG4-SC, as in the case reported here.

<p><strong>Background.</strong> Today there is no clear recommendations regarding the choice of a technique for coronary chronic total occlusion recanalization.<br /><strong>Aim.</strong> The article aims to evaluate the efficacy of choosing the coronary chronic total occlusion primary recanalization strategy according to the CHOICE score in comparison with primary antegrade recanalization.<br /><strong>Methods.</strong> This prospective single-center study included 160 patients with chronic total occlusion. The patients were randomized into two groups: in the first, the recanalization strategy was selected on the basis of the previously developed CHOICE score, in the second, antegrade recanalization technique was used as the primary strategy.<br /><strong>Results.</strong> In the group where the choice of primary recanalization strategy was based on the CHOICE score, technical and procedural success rates were 90% and 88.8% and were significantly higher compared to those in the primary antegrade recanalization group, 76.3% and 75%, respectively. The success rate of the primary recanalization strategy was also higher in the group where choice of the primary recanalization strategy was based on the score (80% vs. 58.8%). At the hospital stage, 2 complications were recorded, one in each group. Thus, a patient in the CHOICE score-based strategy group developed periprocedural myocardial infarction, while the primary antegrade recanalization group there was 1 case complicated by perforation of the coronary artery, which required pericardiocentesis. The average number of stents and contrast did not differ between groups. However, the intervention time was longer in the group with primary antegrade recanalization (47.6 ± 28.2 vs. 39.2 ± 23.4).<br /><strong>Conclusion.</strong> Selecting the CHOICE score-based recanalization can significantly increase the probability of procedural success and reduce the intervention time.<br />Received 17 October 2018. Revised 13 December 2018. Accepted 18 December 2018.<br /><strong>Funding:</strong> The study did not have sponsorship.<br /><strong>Conflict of interest:</strong> Authors declare no conflict of interest.</p>
