
After primary endoscopic hemostasis, PPI infusion
achieved a similar rate of ulcer rebleeding as
compared to scheduled second endoscopy

PPI infusion reduced patients’ discomfort and
endoscopists’ workload from repeating endoscopy

Second endoscopy may have an advantage of
shortening the hospital stay

Second endoscopy should be recommended if PPI
infusion is not available

Embolization in high risk patients

A prospective RCT is ongoing in PWH…

Peptic ulcer rebleeding remains one of the
most important clinical catastrophy with
significant mortality

PPI Infusion after endoscopic therapy prevent
ulcer rebleeding

Schedule 2nd endoscopy served as an
alternative when PPI infusion is not available

Pre-emptive Transarterial embolization may
served as an adjunctive measure to prevent
ulcer rebleeding
