Laparoscopic Adjustable Gastric Banding (LAGB) is a gold standard in the surgical treatment of morbid obesity. We hypothesize that the addition of truncal vagotomy (cutting of nerves to the stomach) will produce greater weight loss and better reduction of co-morbidities (diseases caused by or aggravated by morbid obesity) than LAGB alone. 25 patients will be enrolled and outcomes compared to LAGB historical controls over a post-operative period of 24 months.

Primary Outcome Measures:
  • Excess body weight loss measured @ 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 weeks
  • BMI reduction measured @ 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 weeks
  • Reduction and or elimination of co-morbidities @ 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 weeks

Estimated Enrollment: 25
Study Start Date: May 2006
Study Completion Date: May 2006
Primary Completion Date: May 2006 (Final data collection date for primary outcome measure)
Detailed Description:
The patients will receive standard laparoscopic adjustable gastric banding treatment as well as truncal vagotomy. The vagus nerves will be cut just below the diaphragm using the same access ports that are used during the laparoscopic adjustable gastric banding. During the surgical procedure, the first fifteen patients will also receive a dose of Baclofen, a vagus nerve stimulant, and an endoscopy at the end of the procedure during which congo red dye will sprayed within the stomach. The Baclofen and endoscopy are used to ensure that all branches of the vagus nerve have been cut. If, after 15 complete vagotomies, are verified by the above testing then the use of Baclofen and endoscopy will be abandoned.
