Which of Vonoprazan Alone or Intravenous Proton Pump Inhibitor Followed by Vonoprazan Is Optimal for Reducing Delayed Bleeding in Gastric Endoscopic Submucosal Dissection?
Abstract
Introduction: In gastric endoscopic submucosal dissection (ESD), both vonoprazan alone and intravenous proton pump inhibitor (PPI) followed by vonoprazan have lower delayed bleeding risk than PPI alone. This study aimed to clarify an optimal acid-suppressive method in gastric ESD.
Methods: This population-based cohort study included patients who underwent gastric ESD on only vonoprazan (vonoprazan alone group) or intravenous PPI followed by vonoprazan (intravenous PPI group) using the Diagnosis Procedure Combination database in Japan between 2014 and 2021. The primary outcome was delayed bleeding. To balance the two comparison groups, propensity score matching (PSM), based on 18 variables, was performed; subsequently, to compare the bleeding outcome, logistic regression analysis was performed.
Results: Of 63,952 patients, 24,710 pairs were compared following PSM. The delayed bleeding risk in the vonoprazan alone group was similar to that in the intravenous PPI group (odds ratio [OR], 1.00; 95% confidence interval, 0.93-1.08; delayed bleeding rate, 5.9% vs. 5.9%). The results were consistent in some sensitivity and subgroup analyses; however, the result was modified by the status of antithrombotic agents (p for interaction = 0.029). In additional analyses, in patients with antithrombotic agent, the vonoprazan alone group had a higher delayed bleeding risk than the intravenous PPI group (OR, 1.15).
Conclusion: Both vonoprazan alone and intravenous PPI followed by vonoprazan…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 63,952 participants or records.
