    (BioMed Central, 2019) Reuterwall, Marcus; Lubbe, Jeanne; Enochsson, Lars; Lundell, Lars; Konradsson, Magnus; Swahn, Frederik; Del Chiaro, Marco; Lohr, Matthias; Arnelo, Urban
    Background: Single-operator, per-oral cholangiopancreatoscopy (SOPCP) enables direct biliopancreatic ductal visualization, targeted tissue sampling, and therapeutic intervention. At Karolinska University Hospital, SOPCP was introduced early and has since been extensively utilized according to a standardized protocol. We analysed the clinical value of SOPCP in the diagnosis and treatment of biliopancreatic diseases in a single high volume center. Methods: All SOPCP procedures performed between March 2007 and December 2014 were retrospectively reviewed. Each procedure’s diagnostic yield and therapeutic value was evaluated using a predefined 4 grade scale; 1 - no diagnostic or therapeutic value, 2 - information gained did not impact clinical decision-making and in case of a therapeutic intervention, did not alter the clinical course of the patient, 3 - information gained had an impact on clinical decision-making and in the case of a therapeutic intervention, assisted subsequent disease management, and finally, 4 - information gained was essential and critical for clinical decision-making and in case of a therapeutic intervention, solved the clinical problem requiring no further therapeutic actions. Descriptive statistics were used to analyse results, with uni- and multivariate analyses completed to assess risk of adverse events. Results: During the study period, 365 SOPCP procedures were performed. We found SOPCP of pivotal importance (grade 4) in 19% of cases, and of great clinical significance (grade 3) in 44% of cases. SOPCP did not affect clinical decision-making or alter clinical course (grade 1 and 2) in 37% of cases. Conclusion: SOPCP offers direct access to the biliopancreatic ducts for both diagnostic and therapeutic purposes, adding significant clinical value in 64% of cases.

    Endoscopic stenting for malignant biliary obstruction: results of a nationwide experience
    (Korean Society of Gastrointestinal Endoscopy, 2021-05) Lubbe, Jeanne; Sandblom, Gabriel; Arnelo, Urban; Jonas, Eduard; Enochsson, Lars
    Background/Aims: Many unanswered questions remain about the treatment of malignant hilar obstruction. We investigated endoscopic stenting for malignant biliary strictures, as reported in a nationwide registry. Methods: All endoscopic retrograde cholangiopancreatography (ERCP) procedures entered in the Swedish Registry of Gallstone Surgery and ERCP from January 2010 to December 2017 in which stenting was performed for malignant biliary stricture management were included in this study. Patency was estimated by determining the time to reintervention. Results: Endoscopic stenting was performed for malignant stricture management in 4623 ERCP procedures, of which 1364 (29.5%) were performed for hilar strictures. Of the hilar strictures, 320 (23.5%) were intrahepatic strictures (Bismuth–Corlette III– IV). Adverse events were more common after hilar stenting than after distal stenting (17.2% vs. 12.0%, p<0.0001). The 6-month reintervention rate was 73.4% after hilar stenting compared with 55.9% after distal stenting (p<0.0001). The 6-month reintervention rates for Bismuth–Corlette types I, II, IIIa, IIIb, and IV were 70.4%, 75.6%, 90.0%, 87.5%, and 85.7%, respectively. In multivariate analysis, the risk for reintervention was three times higher after hilar stenting than after distal stenting (hazard ratio 3.47, 95% confidence interval 2.01–6.00, p<0.001). Conclusions: This study with a relatively large patient cohort undergoing endoscopic stenting confirms that stenting for malignant hilar obstruction has more adverse events and lower patency than stenting for distal malignant obstruction.
