¹Positive: Esophagogastroduodenoscopy or side-viewing duodenoscopy observed bleeding from the ampulla of Vater.

²Negative: Esophagogastroduodenoscopy or side-viewing duodenoscopy did not observe bleeding from the ampulla of Vater.

³Positive: Imaging results suggest the cause of hemosuccus pancreaticus.

⁴Negative: Imaging results fail to suggest the cause of hemosuccus pancreaticus. EUS-FNA: Endoscopic ultrasound-fine need aspiration.
