In vitro study of safety and co-efficiency of the transbronchial coagulation techniques.

Background: The usual transbronchial coagulation techniques include microwave, argon plasma coagulation (APC), electrocautery and cryotherapy. However, there are serious clinical problems in the safety of each. By analyzing the experimental data and clinical observations, we observed the variable effects of different coagulation techniques via bronchofibroscopy, to look for an optimal interventional management of luminal bronchus diseases, and evaluate the safety and the equivalent point.
