  Purpose
While gold standard in the treatment of symptomatic gall stones is laparoscopic cholecystectomy with instruments introduced through multiple abdominal wall incisions, transvaginal access to the peritoneal cavity offers an alternative avoiding injury of the abdominal wall. Transvaginal hybrid-NOTES cholecystectomy has been demonstrated effective and safe. However it has not been demonstrated up-to-date if intraoperative cholangiography is feasible during such procedure. This observational case series describes success and technical feasibility of intraoperative cholangiography during transvaginal cholecystectomy. The investigators hypothesis is that cholangiography is feasible equal to conventional laparoscopic cholecystectomy.

Primary Outcome Measures:
  • Number of patients with successful introduction of cholangiography catheter into cystic duct (yes/no) [ Time Frame: intraoperative ]
    Was the introduction of the cholangiography catheter into the cystic duct successfull during transvaginal rigid-hybrid cholecystectomy.


Secondary Outcome Measures:
  • Time required for cholangiography [ Time Frame: intraoperative ]
    From incision of the cystic duct to clipping of the cystic duct

  • Intraoperative complications [ Time Frame: intraoperative ]
  • postoperative complications [ Time Frame: within 6 weeks from surgery ]

Enrollment: 33
Study Start Date: April 2012
Study Completion Date: April 2013
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Women with gallstones
30 women with symptomatic gallstone disease with an indication for elective cholecystectomy
Procedure: Cholangiography during transvaginal rigid-hybdrid NOTES 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.
