Bariatric surgery includes a variety of procedures performed on obese people. The common surgical techniques aim to reduce the size of the stomach and are traditionally performed by laparoscopic surgery. The post-surgical conformation of the stomach is usually defined mostly on clinical basis. Instead, the optimal geometrical configuration should be defined by analysing the mechanical functionality of the stomach and the relationship between food intake, nutrient adsorption, mechanical stimulation of stomach wall and feeling of satiety. A novel approach to bariatric surgery is required, integrating competences in the areas of biomechanics, physiology and surgery, based on a strong interaction between engineers and clinicians. Preliminary results from coupled experimental and computational investigations are here reported. The analyses aimed to develop computational tools for the investigation of stomach mechanical functionality in the pre- and post-surgical configurations.

Abstract

Bariatric surgery includes a variety of procedures performed on obese people. The common surgical techniques aim to reduce the size of the stomach and are traditionally performed by laparoscopic surgery. The post-surgical conformation of the stomach is usually defined mostly on clinical basis. Instead, the optimal geometrical configuration should be defined by analysing the mechanical functionality of the stomach and the relationship between food intake, nutrient adsorption, mechanical stimulation of stomach wall and feeling of satiety. A novel approach to bariatric surgery is required, integrating competences in the areas of biomechanics, physiology and surgery, based on a strong interaction between engineers and clinicians. Preliminary results from coupled experimental and computational investigations are here reported. The analyses aimed to develop computational tools for the investigation of stomach mechanical functionality in the pre- and post-surgical configurations.
