Endoscopic Doppler ultrasound after injection therapy for peptic ulcer hemorrhage

BACKGROUND/AIMS: A positive Doppler signal in endoscopic Doppler ultrasound at index endoscopy predicts a high risk for rebleeding from peptic ulcer. The aim of this study was to evaluate if a negative Doppler status immediately after injection therapy may exclude a rebleeding from peptic ulcer in a high-risk cohort. METHODOLOGY: Twenty consecutive patients (pts) (age: 68 (33-91) yrs; 11 female) with peptic ulcer bleeding were enrolled. All patients with an actively bleeding ulcer and those with a non-actively bleeding, but Doppler-positive ulcer were treated by injection of adrenaline (1:10,000 dilution). Treatment was performed during index endoscopy until the Doppler status was negative. Patients were followed-up clinically and endoscopically (including Doppler ultrasound) for bleeding recurrence. RESULTS: Patients were treated by injection of 12 (6 to 20) mL of adrenaline solution until Doppler scan was negative. During follow-up four pts (20%) had a clinically overt rebleeding episode. At control endoscopy three ulcers were actively bleeding and another two were Doppler positive without rebleeding (total: five of eighteen (27.7%) Doppler-positive ulcers). Two of the twenty pts required surgical therapy due to rebleeding (10%). CONCLUSIONS: A negative endoscopic Doppler status immediately after injection therapy is not helpful to identify patients with no risk for rebleeding from peptic ulcer.
