Primary Outcome Measures:
  • Proportion of Procedures Completed With Successful Endoscopic Visualization. [ Time Frame: Assessed intra-operatively ]
    The goal of the study was to evaluate the feasibility of endoscopic visualization during a laparoscopic sleeve gastrectomy procedure using an endoscope inserted transvaginally through a steerable flex trocar. The number of subjects in whom the procedure was completed with endoscopic visualization was recorded.

Enrollment: 4

  • Unable or unwilling to attend follow-up visits and examinations;
  • Planned or predicted concurrent surgical procedure;
  • Any medical condition which precludes compliance with the study;
  • Immunocompromised such as that resulting from chronic oral steroid use, chemotherapeutic agents, or immune deficiency disorders;
  • Conditions that, in the opinion of the investigator, may jeopardize the subject's well-being and/or the soundness of this clinical study;
  • History or presence of pre-existing autoimmune connective tissue disease, e.g., systemic lupus erythematosus or scleroderma;
