  Purpose

NOTES access is safe and feasible in the controlled human setting and comparable to standard-of-care surgical techniques. NOTES exploration of the abdomen provides adequate visualization comparable to laparoscopy.

Arms Assigned Interventions
Experimental: Prospective
Subjects scheduled to receive procedure
 Procedure: Natural Orifice Transluminal Endoscopic Surgery (NOTES)
Patients will have the standard laparoscopic procedure and the NOTES procedure will be added. The surgical procedure will require two operating teams: one led by a laparoscopic surgeon, the other by an endoscopic surgeon. During the usual course of the surgery, the flexible endoscope will be passed through the mouth urethra top gain access to the peritoneal cavity.

Detailed Description:

This is a prospective clinical trial to evaluate the feasibility of obtaining peritoneal cavity access from natural orifice translumenal endoscopic surgery (NOTES) during combined laparoscopic-endoscopic foregut surgery. Post-operative course will be compared with a historical chart-review control group of patients undergoing standard laparoscopic foregut and urologic surgery.

The study group will be compiled by open enrollment for male and female adult subjects scheduled for combined laparoscopic-endoscopic surgery of the stomach, abdominal esophagus, prostate, bladder, proximal small intestine or who meet inclusion and exclusion criteria. The historical chart-review control group will be randomly chosen from patients from 2003-2006 having undergone combined laparoscopic-endoscopic surgery of the foregut, prostate, or bladder and as determined by CPT coding.

The purpose of the study is to determine if NOTES access and abdominal exploration is feasible, safe, offers comparable visualization to laparoscopy in a controlled human setting.
