Peroral direct cholangioscopic argon plasma coagulation by using an ultraslim upper endoscope for recurrent hepatoma with intraductal nodular tumor growth (with videos).

摘要

Recently, a feasibiiity study on an ultraslim upper endoscope for perorai direct cholangioscopy (PDCS), without a "mother-baby endoscopic system," was reported. However, the therapeutic role of this type -of endoscope for bile-duct lesions is uncertain. We describe the first therapeutic report of PDCS argon plasma coagulation (APC) with an ultraslim upper endoscope for recurrent hepatoma with intraductal nodular tumor growth.
