Summary

A quantifiable arterial bleeding gastric “ulcer” was produced in 6 dogs using the splenic artery with a mean flow rate varying from 50-120 ml/min^-1.

Using a new Neodymium Yag laser system (Barr and Stroud) and glass fibre through a fibreoptic endoscope, bleeding was successfully arrested. Coaxial CO₂ allowed adequate visualization of the spurting vessel and the helium neon laser was a satisfactory marker for aiming.

Key words:

Bleeding ulcer - Coaxial CO₂ - Nd-Yag laser
