Methods: Three patients underwent esophagogastroduodenoscopy. The stomach was aerated to the predetermined level, and internal dimensions were measured using regularly marked endoscopic guidewire. Three-dimensional stomach models were constructed using this information, and individual stomach volumes were calculated. We also planned a simulated sleeve operation or endoluminal bariatric gastroplasty for predetermined volume reduction.

Results: The stomach volume of each patient was acquired and intertemporal variation was calculated. The resection line for sleeve operation and suture lines for endoluminal gastroplasty were planned. Expected volume and shape change after the procedure were obtained.

Conclusion: A patient's stomach volume and shape are important information in surgical or endoscopic volume restrictive procedures. These data can be used for the prediction of treatment response, complications, and prognosis. In the absence of techniques for individualized 3D stomach modeling and volume estimation, this procedure would be an important basic step for future tailored bariatric procedures.

Background: The size and shape of the stomach are variable among individuals and conditions, so an individual three-dimensional (3D) stomach model is important when planning bariatric procedures. If the stomach is aerated to a certain level by endoscopy and the internal space is measured, a 3D stomach model can be constructed precisely. In this study, we constructed a 3D model of the stomach using endoscopy and planned tailored bariatric procedures.
