LapBand Adjustment to Improve Early Weight Loss

This study has been completed.

Crospon Identifier:
First received: January 30, 2010
Last updated: April 4, 2013
Last verified: April 2013
Subjects having a gastric band fitted will have the first band adjustment done at surgery. The stoma will be set to 7mm using the EndoFLIP system to measure stoma size. Thereafter, band adjustments will be made using an adjustment chart, created at surgery, which shows stoma size versus band fill, to make adjustments in the normal follow-up visits. It is hypothesized that an early adjustment at surgery will promote earlier weight loss, and result in fewer band adjustments being required in the first year after surgery.

Enrollment: 35
Study Start Date: October 2009
Study Completion Date: March 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Stoma Adjustment at Surgery
The first band adjustment will be made at surgery versus historical controls where the adjustment is not made for 3-4 weeks post-surgery. EndoFLIP device (FDA Device Listing Number : D091203)will be used to make the adjustment.
Device: EndoFLIP device (FDA Device Listing Number : D091203)
The EndoFLIP balloon catheter will be introduced to the band and used to permit the band stoma size to be adjusted to 7mm.
No Intervention: Historic
Weight loss profile over time for 50 patients in the first 12 months after surgery as derived from historic control records. Band adjustments are made in a heuristic fashion during the year after surgery using the experience of surgeon alone
