Summary
In a randomized, prospective study, 57 patients with a gastroduodenal ulcer and a visible vessel with or without spurting bleeding were treated with a Nd:YAG laser (λ = 1.064 nm). Twenty-eight of these patients were treated using the conventional non-contact (NC) modality, and 29 were treated with the water jet (WJ) laser. Apart from the technical advantages (minimal smoke development, no damage to adjacent structures) the WJ group had a lower rate of induced spurting bleeds (25 % WJ versus 55 % NC). The therapeutic failure/mortality rate of 7 %/0 % respectively for the water-jet group was lower than the 18 %/7 % for the non-contact group. The initial clinical results of this study suggest that the water-jet Nd:YAG laser system is superior to the non-contact system.
