Transluminal Flexible Endoscopic Procedure in Foregut and Urologic Surgery (NOTES)

This study has been completed.

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.
Other Name: NOTES Surgery
Chart review control group
Procedure: Natural Orifice Translumenal Endoscopic Surgery (NOTES)
chart review of historical data from control group
Other Name: NOTES Surgery

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.

Inclusion Criteria:

  • Patients undergoing an already combined laparoscopic and endoscopic foregut procedure with general anesthesia
  • Patients undergoing a prostatectomy or cystectomy with general anesthesia
  • All patients will have a planned gastrotomy for exploration, foreign body removal, or removal of tissue, making it a contaminated case or a planned cystotomy or urethrotomy for exploration, foreign body removal or removal of tissue such as prostatectomy or bladder resection.
  • No overwhelming medical co-morbidities
  • Subject is 18 years of age or older
  • Subject is his or her own medical decision maker
  • Subject agrees to participate, fully understands content of informed consent form, and signs the informed consent form

Exclusion Criteria:

  • Patients undergoing a non-palliative procedure in the face of resectable adenocarcinoma of the foregut or genitourinary tract
  • Linitis Plastica
  • Evidence of Active Bowel Obstruction
  • Patients with history of oropharyngeal, esophageal, or gastric adenocarcinoma.
  • Esophageal stricture prohibiting passage of an endoscope
  • Urethral stricture prohibiting passage of an endoscope
