Total Small Bowel Length Measurement Using Computed Tomography and Magnetic Resonance Imaging in Obese Patients

The intervention consists in performing CT and MR imaging with small bowel length measurement before bariatric/metabolic surgery in obese patients. Then, during surgery the patients will undergo laparoscopic stretched small bowel measurement as the reference gold standard method to measure the small bowel length. The imaging of the training cohort will be used to trained an AI to set up an automatic method of small bowel length measurement via the analysis of CT and MRI imaging.
