Abstract

Background and Aim:

Endoscopic resection is commonly used to remove gastric neoplasms. However, effective dosing or scheduling of proton pump inhibitors for the prevention of delayed bleeding after endoscopic resection remains unclear.

Methods:

One hundred sixty-six patients with gastric adenoma or early gastric cancer were enrolled. After an endoscopic procedure, each subject was randomly assigned to 40 mg every 24 h (standard dose group) or 40 mg every 12 h (double-dose group) of intravenous pantoprazole for 48 h. Second-look endoscopy was performed on day 2 after endoscopic resection to compare signs of rebleeding and ulcer status between the two groups.

Result:

Eighty-one patients of the standard dose group and 81 of the double-dose group were analyzed. There were no significant differences in the incidence of delayed bleeding events (1.3% vs 6.2%, P = 0.21) and bleeding ulcer at the second-look endoscopy (6.2% vs 3.9%, P = 0.69) between standard and double-dose groups. There were no other significant variables associated with delayed bleeding or bleeding ulcer on second-look endoscopy.

Conclusions:

Intravenous pantoprazole 40 mg every 24 h or 12 h for 2 days after endoscopic resection was equally effective for the prevention of delayed bleeding.
