Technical Feasibility of Routine Intraoperative Cholangiography During Elective Rigid-hybrid Transvaginal Natural Orifice Transluminal Endoscopic Cholecystectomy

During transvaginal rigid-hybrid NOTES cholecystectomy a intraoperative cholangiography is performed. After dissection of the Calot's triangle and distal clipping of the cystic duct, the cystic duct is incised and a regular cholangiography catheter is inserted. Contrast is injected and an image is obtained using an image-converter. After extraction of the catheter the cystic duct is clipped proximally. This intervention is performed in all patients included in the study.
