OBJECTIVES: Endoscopic heater probe thermocoagulation and hemoclip are considered to be safe and very effective in the treatment of bleeding peptic ulcer. So far, there are only few reports concerning hemostasis with endoscopic hemoclip. The aims of this study were to compare the hemostatic effects of both therapeutic modalities in patients with peptic ulcer bleeding. METHODS: A total of 80 patients with active bleeding or nonbleeding visible vessels were randomized to receive endoscopic hemoclip (n = 40) or heater probe thermocoagulation (n = 40). RESULTS: Initial hemostasis was achieved in 34 patients (85%) in the hemoclip group and 40 patients (100%) in the heater probe group (p = 0.01277). Rebleeding occurred in three patients (8.8%) in the hemoclip group and two patients (5%) in the heater probe group (p > 0.1). Among patients with difficult-to-approach bleeding, we obtained a better hemostatic rate in the heater probe group (nine of 11 patients vs three of 10, p = 0.02417). The volume of blood transfused after entry into the study, duration of hospital stay, number of patients requiring urgent surgery, and the mortality rate were not statistically significantly different between the two groups. CONCLUSIONS: For patients with peptic ulcer bleeding, heater probe thermocoagulation offers an advantage in achieving hemostasis than hemoclip. In difficult-to-approach bleeders, heater probe is a more suitable therapeutic modality.
