Olympus medical systems corp.(omsc) received a literature titled "very urgent endoscopic retrograde cholangiopancreatography is associated with early discharge in patients with non-severe acute cholangitis".Literature summary background: endoscopic retrograde cholangiopancreatography (ercp) is a first-line procedure for biliary drainage in patients with acute cholangitis, and there are no studies focused on very urgent ercp within several hours of hospital arrival.This study aimed to elucidate the use of very urgent ercp for non-severe acute cholangitis.Methods: this retrospective observational study included patients with non-severe acute cholangitis who underwent ercp between april 2011 and june 2020 in our institution.Patients were stratified into three groups based on time to ercp after hospital arrival: very urgent (= 3 hours), urgent (3-24 hours) and elective (> 24 hours).The primary outcome was length of hospital stay (los).Results: this retrospective, observational cohort study was to elucidate the use of very urgent endoscopic retrograde cholangiopancreatography (ercp) as performed within = 3 hours after hospital arrival for non-severe acute cholangitis (ac), by comparing with ercp as performed > 3 hours after hospital arrival.A total of 291 patients were included (47 patients (very urgent group), 196 patients (urgent group), and 48 patients (elective group).A shorter los was associated with earlier ercp (log-rank trend test, p = 0.04).The rates of readmission within 30 days of discharge and of adverse events were not significantly different among the three groups.The multivariate analysis showed that, compared with the very urgent group, the hrs were significantly lower in the urgent (hr, 0.71, p = 0.04) and elective (hr, 0.47, p < 0.01) groups.Very urgent ercp for non-severe acute cholangitis was associated with early discharge.Conclusions: very urgent ercp for non-severe acute cholangitis was associated with early discharge.Type of adverse events/number of patients very urgent readmission within 30 days of discharge - 3 patients pancreatitis - 3 patients acute cholecystitis - 1 patient urgent pancreatitis - 11 patients readmission within 30 days of discharge - 5 patients elective readmission within 30 days of discharge - 1 patient pancreatitis - 2 patients this literature article requires 3 reports.The related patient identifiers are as follows: 1.(b)(6) - tjf-240 2.(b)(6) - jf-260v 3.(b)(6) - tjf-q290v this medwatch report is for (b)(6).There is no report of any olympus device malfunction in any procedure described in this study.
