Comparison of histological effect of electrocoagulation and Nd-YAG laser coagulation in intact and tumorous rat tissue.
In our animal experiments we used a chemical agent (dibutylnitrosamine) to induce urinary bladder tumor in rats, then this was implanted under the dorsal skin of rats of the same strain to gain a standard tumor preparation. The histological effects of electrocoagulation and Nd-Yag laser coagulation were compared in rat striated muscle, liver, intact rat urinary bladder and in our standard tumor preparation. The histological changes suggested that laser coagulation has advantages over electrocoagulation for inducing deep and homogenous necrosis in intact and tumorous tissues.
