Brief summary

During surgery for obesity, minimally invasive endoscopy can be performed and can assist the surgeon in determining surgical incision sites.

Detailed description

Transgastric endoscopic access, without laparoscopic guidance, to the peritoneal cavity can be performed safely and guide trocar placement in morbidly obese patients undergoing Roux-en-y gastric bypass.

Interventions
