Argon plasma coagulation (APC) is a new technique of non-contact electrocoagulation which now can also be used in digestive endoscopy. Unipolar current is applied to the tissue by means of ionized argon gas flow, through a probe fitting to flexible endoscopes' working channel. The APC coagulation is uniform and no more then 3 mm deep. Operative distance between probe tip and tissue is to be kept at 2-10 mm because the current does not work when the distance is beyond this range. 18 patients with digestive diseases underwent 23 APC sessions: 12 large colorectal adenomas, 1 malignant adenoma and 1 polipoid rectal cancer after endoscopic piecemeal polipectomy; one colonic angiodisplasia; one bleeding cardial erosion; 2 esophageal cancers, one of which was ingrowth through an uncovered self-expanding esophageal endoprosthesis. The treatment was always well tolerated and complications were not observed. In our preliminary experience, endoscopic APC resulted to be an easier and safer therapeutic technique than standard coagulation. Moreover, APC is safer than Nd:YAG laser photocoagulation in presence of thin visceral walls and when visceral overinflation can not be early controlled, but it is less to treat large tumors. Good immediate results were observed, but a larger number of treated cases and a longer follow up period are required for definitive results.
