Endoscopic Gastric Reduction for Weight Management

April 6, 2015 updated by: Barham K. Abu Dayyeh, M.D., Mayo Clinic

Endoscopic Gastric Reduction for Weight Management: A Pilot Feasibility Study

The proposed study is a prospective, pilot study to assess the feasibility of a novel endoscopic suturing system to reduce gastric volume by changing the shape of the stomach for the primary treatment of obesity. The investigators aim to recruit ten subjects with a body mass index between 30-40 for this study. Vertical sutures will be performed using the endoscopic suturing system to deploy 10-17 interrupted full thickness sutures. Botulinum toxin(approximately 30 units) will be injected around the sutures insertion sites in half of the subjects randomly to slow down muscular grinding of the stomach to see if it improves durability of the procedure.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Botulinum toxin at injection site
All subjects will have gastroplasty performed using the Overstitch Endoscopic Suturing System. Botulinum toxin will be injected in every other suture site in half of the randomly patients selected.
Drug: Botulinum toxin
In this study, Botulinum toxin will be injected in half of the subjects not as a primary treatment modality for obesity, but to retard the muscular grinding gastric activity arount the suture insertion sites to see if it improves the durability of the gastroplasty.
Other Names:
  • Botox
Device: Overstitch Endoscopic Suturing System
The gastroplasty will be accomplished by a series of intralumenally placed full thickness interrupted sutures through the gastric wall, using the FDA-approved (510K) endoscopic suturing device, the Overstitch Endoscopic Suturing System.
