Scheduled second-lookendoscopy
Is it useful ?
Scheduled second-look endoscopy Rationale– To treat before clinical rebleeding occurs– To perform second-look OGD within 16 – 24 hours after
primary endoscopic hemostasis

Q
What type of surgery to do?Conservative surgery Definitive surgery

P<0.05
Q What type of surgery to do?
Results before the era of PPI may not be reliable
ConclusionHigh-dose IV PPI infusion is useful in reducingrebleeding, emergency operation and mortality
Second-look endoscopy is useful in preventing rebleeding in high-risk patients
Both endoscopic re-treatment and surgery should be selectively applied to rebleeding patients
The choice between conservative and definitiveSurgery is still controversial
