Forrest-type IIb increases the risk of rebleeding after endoscopic treatment in patients with Dieulafoy’s lesion of the upper gastrointestinal tract

Background Dieulafoy's lesion (DL) is a rare cause of nonvariceal upper gastrointestinal bleeding (NVUGIB) and represents a significant clinical challenge. This research aimed to identify the potential risk factors contributing to DL rebleeding after endoscopic hemostasis, including patient characteristics and laboratory and endoscopic findings such as the Forrest classification.
