A Trial to Evaluate Natural Orifice Transvaginal Endoscopic Cholecystectomy With Laparoscopic Assistance

The study will document being able to successfully remove a subject's gallbladder through the vagina (laparoscopic visualization)using a small collection of study surgical tools.

3. Have a clinical diagnosis of gallbladder disease indicated for cholecystectomy;
4. ASA Classification I or II (Appendix II);
5. Have a negative serum pregnancy test (for women of childbearing potential); and
6. Absence, on visual inspection, of adhesions judged to be a potentially complicating factor in transvaginal access and operation.

7. Pelvic Inflammatory Disease;
8. Evidence of abdominal abscess or mass;
9. Diffuse peritonitis;
10. Use of anticoagulants or anti-platelet agents (use of daily cardio protective doses of aspirin, up to 81 mg/day, is acceptable and shall not constitute an exclusion criterion) or the presence of coagulopathy;
11. Clinical diagnosis of sepsis;
12. History of ectopic pregnancy, pelvic inflammatory disease, or severe endometriosis;
13. History of peritoneal or vaginal trauma;
14. Co-morbid condition(s) that could limit the subject's ability to participate in the study or to comply with follow-up requirements, or that could impact the scientific integrity of the trial;
15. Planned concurrent surgical procedure;
16. Prior or planned major surgical procedure within 30 days before or after study procedure;
17. History of transvaginal surgery;
18. History of (or symptomatic for) abdominal adhesions;
19. Participation in any other investigational device or drug trial that has not completed the primary endpoint or that clinically interferes with the current study endpoints;
20. Previously enrolled in the current series of 4 trials investigating the EES NOTES GEN1 Toolbox;
21. Any contraindication listed in a study device Instructions for Use (IFU) document (if that device may be used in the study procedure); or
22. Any condition which precludes compliance with the study (Investigator discretion).
