Primary Outcome Measures:
  • Completion of Diagnostic Peritineoscopy [ Time Frame: Assessed intra-operatively as the time from first insertion of the flexible trocar into the oral cavity to final withdrawal of the flexible trocar ]

    Number of participants in which transgastric access was achieved using the EES NOTES GEN1 Toolbox

    Outcome description: Completion of diagnostic peritoneoscopy after transgastric access was completed using a flexible, steerable trocar. Because this was a feasibility trial, transgastric access was the primary outcome.

Enrollment: 7
Study Start Date: June 2009
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: NOTES Toolbox
Multiple devices designed for trans-orifice use during surgical procedures; used for transvaginal cholecystectomy in this trial
Device: Transgastric diagnostic peritoneoscopy with laparoscopic assistance

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Men and women will be enrolled in this study who:

  • Are willing to give consent and comply with evaluation and treatment schedule;
  • At least 18 years of age;
  • Are a candidate for surgical weight loss intervention (i.e. meet ASMBS and NIH criteria) for an RYGB procedure at the Investigational site;
  • Have a history of open abdominal surgery or laparoscopic abdominal surgery;
  • ASA Classification I, II, or III (Appendix II); and
  • Have a negative serum pregnancy test (for women of childbearing potential).

Exclusion Criteria:

Subjects will be excluded from the study for any of the following:

  • Use of immunosuppressive medications (within 6 months of surgery; single burst dosages and inhalable steroids are acceptable);
  • Acute cholecystitis or acute pancreatitis;
  • Evidence of abdominal abscess or mass;
  • Diffuse peritonitis;
  • 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;
  • Clinical diagnosis of sepsis;
  • 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;
  • Planned concurrent surgical procedure other than RYGB or adhesiolysis;
  • Prior or planned major surgical procedure within 30 days before or after study procedure;
  • 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;
  • Previously enrolled in the current series of 4 trials investigating the EES NOTES GEN1 Toolbox; or
  • Any condition which precludes compliance with the study (Investigator discretion).
