title: A novel endolaparoscopic intragastric partitioning for treatment of morbid obesity.
abstract: Morbid obesity is a burgeoning health crisis. Significant morbidity is associated with the current gastric bypass, and, therefore, alternative surgical modalities are desired. A novel minimally invasive surgical technique, endoluminal gastric partitioning, is presented. Ten mongrel dogs underwent endolaparoscopic placement of intragastric mesh. Each circular prosthesis (Surgisis or prolene mesh) was 8 cm in diameter with a 1.5 cm central aperture. The mesh was passed transorally into the gastric lumen and secured with a laparoscopic, intragastric suturing resulting in a 30 to 50 mL proximal gastric reservoir. The operation was successfully completed in all 10 animals. Nine of 10 animals were healthy at the scheduled sacrifice date. In 2 dogs, the intragastric mesh was 100% adherent to the gastric mucosa after 7 days. Four of the final 5 dogs demonstrated some degree of mucosal adherence after 1 week. Endoluminal placement of intragastric mesh appears feasible and safe. Long-term studies are necessary to demonstrate the efficacy and long-term weight loss of this, or alternate intraluminal gastric partitioning techniques.
