Abstract:
In some cases, in addition to the usual difficulties that the bariatric surgeon may encounter during standard bariatric procedures, anatomical anomalies such as situs inversus can pose an additional technical challenge. A 58-year-old patient with total situs inversus underwent Roux-en-Y gastric bypass (RYGB) surgery in our department. The main difficulty was the realization of a mirrored RYGB. Laparoscopic RYGB in a patient with situs inversus totalis is feasible but requires significant concentration and three-dimensional coordination to perform the mirrored procedure.
