A prospective, randomized trial of endoscopic band ligation versus endoscopic hemoclip placement for bleeding gastric Dieulafoy's lesions

Abstract

Background and study aims: Dieulafoy's lesion is a rare cause of massive gastrointestinal hemorrhage, most commonly in the proximal stomach. Mechanical endoscopic methods have recently become the standard therapeutic approach. However, there have been few studies comparing the efficacy of different mechanical endoscopic methods in treating gastric Dieulafoy's lesions. This study was therefore carried out to compare the hemostatic efficacy and safety of endoscopic band ligation (EBL) and endoscopic hemoclip placement (EHP) in the treatment of bleeding gastric Dieulafoy's lesions.

Patients and methods: Between January 2002 and October 2003, 26 consecutive patients with bleeding gastric Dieulafoy's lesions were prospectively enrolled and were randomly assigned to undergo EBL (13 patients) or EHP (13 patients). Demographic characteristics, endoscopic variables, and outcome parameters, including rates of hemostasis and recurrent bleeding, were analyzed.

Results: One O-ring was applied in each case in the EBL group, and the median number of hemoclips applied was one (range one to four) in the EHP group. There were no significant differences between the groups with regard to age, sex, presence of shock, initial hemoglobin level, coagulopathy, concurrent diseases, location of the lesion, type of bleeding stigmata, blood transfusion requirements, or hospitalization periods. Primary hemostasis was achieved in all 26 patients. There was one case of recurrent bleeding in each group; secondary hemostasis was achieved with EBL in one of these patients and by endoscopic epinephrine injection in the other. There were no second episodes of recurrent bleeding, no procedure-related complications, no cases in which surgery was needed, and no bleeding-related deaths in either group.

Conclusions: In this small study, no differences were detected in the efficacy or the safety of EBL vs. EHP in the management of bleeding gastric Dieulafoy's lesions.
