Laparoscopic Gastric Plication  No stomach stapling or removal  low leak risk, low bleeding risk  No bypass  minimal nutritional risk  no bowel re-routing  No foreign body (i.e. band)  no prolapse or erosion risk  Potentially reversible or modifiable to another procedure if needed  Minimally invasive; short stay  Lower cost

LGCP Normal Endoscopic Appearance Invagination of the greater curvature results in decreased intraluminal gastric volume Normal, intact plication results in lobular contour abnormalities and intraluminal filling defects on imaging

Comparison to Other Studies

Complications No bleeding or infectious complications First GCP patient required reoperation and plication reduction on POD#2 due to gastric obstruction Mild to moderate nausea in all patients (2 severe). Resolved within two weeks. One GCP patient required laparoscopic cholecystectomy 11 months after procedure Brethauer SA et al. SOARD :15-22

Plication with Gastric Banding

Laparoscopic Gastric Plication Summary Anterior Plication safe, but not effective Greater Curve Plication – Technically feasible, reproducible – Good short-term weight loss – Low major complication rate – Remains investigational (ASMBS Position Statement)
