Abstract

It has been shown that three-dimensional radiological reconstruction from CT scan images is very useful in the preoperative planning of complex cases using the patient's preoperative studies. It has been seen to have the most benefit in hepatobiliary and colorectal surgery. Different reconstruction means have been proposed, but all of them are considered validated to plan the critical steps of the intervention. This paper presents our 3D reconstruction model of post-bariatric surgery anatomy, to propose its applicability in revisional surgery. Anatomical models of three-dimensional stomach imaging and post-surgery anatomy have been developed. CT scan images are obtained with the Siemens Somatom Perspective 64equipment. Image recovery is in DICOM format and the processing to achieve three-dimensional reconstruction is done with the OsiriX computer program, performing a complete segmentation of the entire surface to be reconstructed, and a modification of image density. The obtaining of three-dimensional reconstruction images of post-bariatric surgery anatomy allows to develop models that can improve preoperative planning in revision surgery cases, but the risk-benefit of the radiation produced by the CT scan must be assessed to do it systematically.
