Abstract Background There is a lack of studies regarding the optimal timing for endoscopic retrograde cholangiopancreatography (ERCP) in patients with cholangitis caused by distal malignant biliary obstruction (MBO). This study aims to investigate the optimal timing of ERCP in patients with acute cholangitis associated with distal MBO with a naïve papilla. Methods A total of 421 patients with acute cholangitis, associated with distal MBO, were enrolled for this study. An urgent ERCP was defined as being an ERCP performed within 24 h following emergency room (ER) arrival, and early ERCP was defined as an ERCP performed between 24 and 48 h following ER arrival. We evaluated both 30-day and 180-day mortality as primary outcomes, according to the timing of the ERCP. Results The urgent ERCP group showed the lowest 30-day mortality rate (2.2%), as compared to the early and delayed ERCP groups (4.3% and 13.5%) (P < 0.001). The 180-day mortality rate was lowest in the urgent ERCP group, followed by early ERCP and delayed ERCP groups (39.4%, 44.8%, 60.8%; P = 0.006). A subgroup analysis showed that in both the primary distal MBO group, as well as in the moderate-to-severe cholangitis group, the urgent ERCP had significantly improved in both 30-day and 180-day mortality rates. However, in the secondary MBO and mild cholangitis groups, the difference in mortality rate between urgent, early, and delayed ERCP groups was not significant. Conclusions In patients with acute cholangitis associated with distal MBO, urgent ERCP might be helpful in improving the prognosis, especially in patients with primary distal MBO or moderate-to-severe cholangitis.

Background Self-expanding metal stents (SEMSs) are recommended in unresectable distal malignant biliary obstruction. However, problems with dysfunction and migration of these stents are not negligible. We aimed to investigate the effectiveness and safety of a new 12-Fr plastic stent. Methods In an observational, prospective study, all consecutive patients who underwent biliary stenting with the 12-Fr stent were considered (index group). Referent groups were a historical cohort, matched by sex, etiology, and metastatic status, including patients with 10-Fr plastic stents and with fully covered and uncovered SEMSs (FCSEMSs and UCSEMSs). Outcomes were stent patency, recurrent biliary obstruction (RBO), technical success, 30-day mortality and adverse events. A post-procedure examination of removed stents was done. Results 72 patients (median age 66, range 32 – 94 years, 50 % men) were included (24 index, 48 referents). There were no differences in median stent patency time (P = 0.684). RBO was significantly lower with the 12-Fr compared with the 10-Fr profile stent (50 % vs. 81.3 %, P = 0.04), but no difference was found compared with the FCSEMSs (50 % vs. 43.8 %, P = 0.698). Technical success was 100 %, with no differences in 30-day mortality P = 0.105). The adverse events rate was 4.2 % for both groups (index n = 1, referents n = 2). Of 11 removed 12-Fr plastic stents suspected to be dysfunctional, 7 (64 %) were still patent. Conclusions This new 12-Fr plastic stent could be an effective and cheaper alternative to SEMSs in distal malignant biliary obstruction.
