Background: post-sphyncterotomy endoscopic retrograde cholangiopancreatography (ERCP) bleeding is an adverse event with an estimated incidence rate of 1.34%. There is no established consensus about how to treat this particular type of gastrointestinal bleed. Placement of fully covered self-expandable biliary metal stents (FCSEBMS) has been evaluated as an alternative treatment with positive outcomes and a low complication rate. Aim: to report the results of a cohort of patients with post-sphyncterotomy bleeding treated in a tertiary care referral hospital with FCSEBMS. Methods: a retrospective cases series study was performed including all post-ERCP bleeds treated with FCSEBMS (immediate or delayed) from January 2015 to June 2017. Clinical data, laboratory results and endoscopic reports were collected in order to evaluate the rebleeding rate after endoscopic treatment. Two different scenarios were considered: a) prophylactic stent placement after effective endoscopic treatment; and b) stents placed for the treatment of an active postsphyncterotomy bleed, refractory to standard endoscopic therapy. Results: twenty-two patients (14 male, eight women) diagnosed with postsphyncterotomy bleeding were treated with FCSEBMS placement. The stents were placed prophylactically in 15 patients, while the stents were placed as a treatment for a refractory bleed in seven patients. No differences were found between both groups except for a higher anticoagulation rate in the treatment group. Clinical success was achieved in all but one patient, with no complications in relation to stent placement. Distal migration was described in two of the 22 patients included in the study. Conclusions: temporary placement of FCSEBMS seems to be a technically feasible treatment option for post-ERCP bleeding with a high clinical success rate. The complication rate was low, although randomized studies are needed.
