title: [Comparison on Oral versus Intravenous Proton Pump Inhibitors for Prevention of Bleeding after Endoscopic Submucosal Dissection of Gastric Lesions].
abstract: OBJECTIVE
  Although intravenous proton pump inhibitor (PPI) has been used for the prevention of post endoscopic submucosal dissection (ESD) bleeding, the route of administration has not been confirmed. The aim of the present study was to compare the efficacy of intravenous and oral PPI administration for the prevention of delayed post ESD bleeding.
  
  
  METHODS
  Total 166 consecutive patients were randomly assigned to 30 mg lansoprazol twice a day (PO group) and 120 mg pantoprazole intravenous injection (IV group) for 48 hours. Finally, 65 patients in PO group and 87 patients in IV group were analyzed. After ESD, all patients underwent follow up endoscopy after 24 hours and were observed the symptoms of bleeding up to 60 days after ESD.
  
  
  RESULTS
  Age, sex and use of anticoagulants were not different between groups. At follow up endoscopy after 24 hours, oozing and exposed vessel was noted in 4.6% of PO group and 8.0% of IV group and there was no significant difference. Delayed bleeding occurred in 4 of 65 patients (6.2%) in the PO group and 8 of 87 patients (9.2%) in the IV group (p>0.999). By multivariate analysis, oozing or exposed vessels at follow up endoscopy were risk factors for delayed bleeding (OR=17.5, p=0.022).
  
  
  CONCLUSIONS
  There was no significant difference in the delayed bleeding, length of hospital stay according to the administration route. Bleeding stigmata at follow up endoscopy was risk factor of delayed bleeding. Oral PPI administration can cost-effectively replace IV PPI for prevention of post ESD bleeding.
