Clinical and economic comparative analysis of laparotomy versus laparoscopy in the first gastric bypass surgeries in a bariatric and metabolic surgery service in a city in southern Brazil.

Introduction: this paper aims to evaluate the main direct and indirect costs of the first laparotomies and laparoscopies in bariatric surgeries with a clinical-economical retrospective and cross-sectional analysis from 2017 to 2020 at a hospital with specialties besides the basic ones in southern Brazil.
Methods: the study sample included 26 participants. The first 13 laparotomies, and the first 13 laparoscopies performed at the bariatric surgery service of the institution were evaluated. The values evaluated in such comparison analyzed the costs of operation and hospitalization. It is important to highlight that, in addition to the cost benefit, other costs take significance in the health area, such as: cost-utility, cost-effectiveness and cost-minimization, in addition to the cost-opportunity that is reassessed in the observation of the broad context associating all the values raised here. The software used for data analysis was Excel version® 365. The economic analysis was performed evidencing the profile of the patients and the direct and indirect costs involved in each segmentation.
Results: the direct and indirect costs of videolaparoscopy amounted to BRL 10,108.10 and laparoscopy to the amount of BRL 12,568.14.
Conclusion: it was concluded that laparoscopy presents more savings in the aspects of all health valuations to the detriment of laparotomy. It was concluded that the videolaparoscopy presents more savings in the aspects of all health valuations than the laparotomy.
