ORAL RABEPRAZOLE ADMINISTRATION ON A PROCEDURE DAY SUPPRESSES BLEEDING AFTER ENDOSCOPIC SUBMUCOSAL

Abstract: [Aim] The efficacy of pre-procedure oral proton pump inhibitor (PPI) administration for gastric endoscopic submucosal dissection (ESD) is unclear. This study evaluated oral PPI adminis-tration effectiveness on the day of ESD to prevent post-ESD bleeding. [Methods] This study ex-amined 55 patients who underwent ESD for gastric neoplasm. Group A comprised 31 patients who took rabeprazole sodium (RPZ) 20 mg/day beginning 7-8 hr before ESD. Group B comprised 24 who took RPZ 20 mg/day beginning three days before ESD. Gastric pH (G-pH) was measured at one month before ESD (pre-ESD pH), immediately before ESD (ESD pH), and seven days after ESD (post-ESD pH). The post-ESD bleeding rate and changes in G-pH were recorded. [Results] No significant difference in post-ESD bleeding rates was found (Group A 3.2%, Group B 0%). ESD pH and post-ESD pH were significantly higher than pre-ESD pH in both groups (P<0.001). The ESD pH for Group A was higher than 6 (6.5±1.1), providing hemostasis for intragastric bleeding. [Conclusions] Oral RPZ administration on the day of gastric ESD can suppress post-ESD bleedin
