Primary Outcome Measures:
  • The achievement of safe transgastric access to the abdomen; the ability to visualize the abdominal wall to assist in safe trocar placement in the morbidly obese patient. [ Time Frame: At surgery ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Bacterial contamination analysis; results compared to previous study. [ Time Frame: Surgery ] [ Designated as safety issue: Yes ]

Enrollment: 60
Study Start Date: July 2007
Study Completion Date: November 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
10 patients with no previous abdominal surgeries, pre-insufflation of the abdomen using a veress needle (standard procedure for insufflating the abdomen for laparoscopic surgery)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.
Active Comparator: 2
10 patients with history of previous abdominal surgeries, pre-insufflation of the abdomen using veress needle (standard procedure for insufflating the abdomen for laparoscopic surgery)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.
Active Comparator: 3
10 patients with no previous history of abdominal surgeries, no veress needle pre-insufflation (insufflating the abdominal cavity through the endoscope, transgastrically)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.
Active Comparator: 4
10 patients with history of previous abdominal surgeries, no veress needle pre-insufflation (insufflating the abdominal cavity through the endoscope, transgastrically)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.
Active Comparator: 5
10 patients, all with no previous mid to upper abdominal surgeries, no Veress needle pre-insufflation (insufflating the abdominal cavity through the endoscope, transgastrically)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.
Active Comparator: 6
10 patients, all with previous mid-to-upper abdominal surgeries, no Veress needle pre-insufflation, endoscopic take-down of intra-abdominal adhesions (if identified)
Procedure: Transgastric access to the abdomen
Upper endoscopy, gastrotomy created with a needle knife followed by lower endoscopy.

Detailed Description:

Transgastric endoscopic access, without laparoscopic guidance, to the peritoneal cavity can be performed safely and guide trocar placement in morbidly obese patients undergoing Roux-en-y gastric bypass.
