Laparoscopic Roux-en-Y gastric bypass in a patient with situs inversus totalis: case report.

The purpose of this report is to present the case of a patient with situs inversus totalis (SIT) who underwent laparoscopic gastric bypass and review of the literature. Situs inversus is a rare congenital abnormality that occurs in ~0.01% of the population and is characterized by transposition of the abdominal viscera1. When associated with dextrocardia, it is known as SIT. Electrocardiography reveals a reversal of the electrical waves of the heart and is the diagnostic measure of choice. Roux-en-Y laparoscopic gastric bypass for morbid obesity is one of the most effective bariatric procedures currently considered as the gold standard in bariatric surgery. We present the case of a 19-year-old male with morbid obesity and diagnosis of SIT, who underwent a laparoscopic gastric bypass adjusting the technique to the anatomical changes typical of this variant. It can be concluded, based on the previously compared cases and what was reported in ours, that in patients who have an indication to perform bariatric surgery and present SIT, surgery is not contraindicated, obtaining favorable results.
