Background: Obesity usually refers to, very fat accumulation. On the other hand, overweight refers to moderate fat accumulation. Abdominal Computerized Axial Tomography (CAT) ideally completed by using oral and intravenous contrast agents. This CT study aimed to learn about and identify the normal anatomy following laparoscopic sleeve gastrectomy (LSG), as well as to identify any issues that may have developed as a result of this procedure. Objective: Review of the computerized axial tomography role in detection of complications of laparoscopic sleeve gastrectomy. Methods: We scoured scholarly journals and databases including PubMed, Google Scholar, and Science Direct for reports on laparoscopic sleeve gastrectomy and computerized axial tomography. Between November 2005 and April 2022, however, only the latest or most comprehensive study was considered. The authors also assessed the usefulness of references drawn from similar books. As a result, non-English documents have been overlooked due to a lack of resources to translate them. It was commonly recognized that scientific research did not include things like unpublished publications, oral presentations, conference abstracts, or dissertations. Conclusion: CT is very important in the diagnosis of early complications after LSG. Splenic infarction was clearly observed with CT angiography, after dividing the short stomach vasculature, the ischemic patches were visible on inspection of the laparoscopic pictures, and it helped for differentiation and diagnosis of several early complications as hemorrhage, stricture, fistula, splenic infarction as well as other wound complications.
