Abstract

Background and study aims Bleeding is a common complication of following endoscopy sphincterotomy (EST), and antithrombotic therapy use during the procedure often increases risk of it. Although several guidelines have been released regarding the use of antithrombotic agents during EST, many issues about it remain controversial. We carried out a systematic review and meta-analysis to evaluate the effect of antithrombotic medication on the risk of EST bleeding.

Methods A structured literature search was carried out in Web of Science, EMBASE, PubMed, and Cochrane Library databases. RevMan 5.2 was used for meta-analysis to investigate the rate of post-EST bleeding.

Results Seven retrospective articles were included. Compared with patients who had never taken antithrombotic drugs, patients who discontinued antithrombotic drugs 1 day before the procedure had a significantly increased risk of post-EST bleeding (OR, 1.95; 95 %CI, 1.57–2.43), particularly for severe bleeding (OR, 1.83; 95 %CI, 1.44–2.34). In addition, compared with patients who discontinued antithrombotic therapy for at least 1 day, patients who continued taking antithrombotic drugs did have an increased risk of post-EST bleeding (OR, 0.70; 95 %CI, 0.40–1.23).

Conclusions The use of antithrombotic drugs may increase the bleeding rate of EST, but discontinuing therapy 1 day before endoscopy does not significantly reduce the bleeding rate.
