Situs Inversus Totalis in Laparoscopic Sleeve Gastrectomy: A Case Report.

Obesity is a pathology that is increasing in incidence globally and threatens public health. Currently, one of its most effective treatments is bariatric surgery, which has shown the best long-term results. One of the most frequently performed surgical procedures in this area is laparoscopic sleeve gastrectomy (LSG) or vertical sleeve. It is a restrictive technique that has had positive results in weight loss. Situs inversus totalis (SIT) is a strange condition with a low incidence in which thoracic and abdominal organs are on the opposite side of the already-known anatomic site, seen on a sagittal plane. The high demand for laparoscopic bariatric surgeries predisposes surgeons to find rare congenital anomalies in patients. Low prevalence and the anatomic mirror image condition may be challenging even for expert surgeons. Medical teams need to have knowledge of these cases and adjust the technique and procedure to complete the surgery without complications. We present a SIT case successfully treated with LSG in a male patient in Mexico.
