Experience with the ENDOCAMELEON in vNOTES (Transvaginal Natural Orifice Transluminal Endoscopic Surgery)

Abstract

　This report describes our experience using ENDOCAMELEON in Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES). vNOTES, introduced in Japan in 2020 with the GelPOINT V-Path, has rapidly gained popularity due to its minimal invasiveness and aesthetic benefits. However, the procedure presents challenges, particularly in securing a clear operative field and avoiding interference with instruments. ENDOCAMELEON, which allows flexible viewing angles between 0° and 90°, was used in five cases performed between August and October 2024. The system proved effective in securing a clear view during surgery. We found it particularly useful in overcoming the difficulties of single-port surgery, improving the surgical field visibility without requiring additional working space. Further investigation into optimal usage and more cases are necessary to validate its benefits.
