RESUMO
BACKGROUND: By argon plasma coagulation (APC), a current is applied to tissues as ionised gas. Special probes have recently been developed for applying the gas through flexible endoscopes. In the field of therapeutic endoscopy, this method is promising for several diseases in the gastrointestinal tract. MATERIAL AND METHODS: At Ostfold Hospital in Fredrikstad, Norway, 122 treatments in 80 patients were performed during the years 1997-99. RESULTS: The new method was useful for endoscopic treatment of haemorrhages, tumour debulking and tumour ingrowth and overgrowth in oesophageal stents. Abdominal pain was related to insufflation of air and gas. Complications related to the method were not observed. INTERPRETATION: Our experience with this new method was very positive. The method was effective, had a very low complication rate, and the equipment was easy to use. The application of APC in premalignant conditions is discussed.
