Study type
Description of intervention(s) / exposure
The intervention is performed at the end of the laparoscopic gastric band removal before removing all the laparoscopic ports. It is a Polymer Kit containing two precursor solutions, a polyethylene glycol (PEG) ester trilysine amine solution and a borate buffer solution. These are mixed together causing the precursors to link forming a synthetic, absorbable, hydrogel adhesion barrier. The reconstituted Polymer Kit syringes are attached to an applicator to allow the polymer to be sprayed onto the operative field. Upon spraying, the polymer liquids mix and rapidly cross-link to form a thin, flexible, tissue adherent, hydrogel adhesion barrier.

Brief summary
A randomised trial to determine whether using a sprayable adhesion barrier onto the operative field during removal of a gastric band will make a future laparoscopic sleeve gastrectomy quicker and safer due to reduced scar formation where the gastric band used to be.
