Event Description

Olympus medical systems corp.(omsc) received a literature titled "competence development of trainees performing short-type single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy.¿ objectives: this study aimed to evaluate the trainees' practice and learning curve in short-type single-balloon enteroscopy (short sbe)-assisted endoscopic retrograde cholangiopancreatography (ercp) for patients with surgically altered anatomy (saa) and determine how to train these trainees.Methods: the data of short sbe-assisted ercp procedures between september 2011 and june 2021 were analyzed.Results : three trainees and 180 cases were included in the analysis.Each trainee performed 60 cases between april 2016 and june 2021.The trainees' completion rate was 73.9% (95% confidence interval [ci], 66.8-80.1%).Adverse events occurred in 5.0% of cases (95% ci, 2.3-9.3%).The trainee who experienced colonoscopy and ercp the most achieved better outcomes of enteroscopy success (reaching the target site) and trainee's completion rates than those of the others (p =.03 and.02, respectively).The learning curve for trainee's completion showed a significant improvement after 60 cases (p =.001).Multiple logistic regression analysis indicated that roux-en-y reconstruction was the factor affecting trainees' completion failure.Conclusions: short sbe-assisted ercp trainees has a substantial learning curve.If trainees do not have much experience with colonoscopy and ercp procedures, it may be beneficial for them to start performing short sbe-assisted ercp procedures on non-roux-en-y reconstruction cases.Type of adverse events/number of patients.Pancreatitis/4.Cholangitis /4.Intestinal perforation /1.This literature article required 3 reports.The related patient identifiers are the following: (b)(6): sif-h290s.(b)(6): d-201-10704.(b)(6): sif-h290s.This medwatch report is for patient indentifier: (b)(6).There is no report of any olympus device malfunction in any procedure described in this study.
