Abstract
Situs inversus totalis (SIT) is a rare genetic autosomal recessive disorder; however, in identical twins, it may be misinterpreted as X-linked disorder. SIT describes a 270 degrees counterclockwise rotation of the intra-abdominal organs. Laparoscopic surgery in patients with SIT may be more difficult than in normal patients due to its mirror image anatomy. We report a case of a morbidly obese patient (body mass index 36 kg/m(2)) with SIT who underwentsuccessful laparoscopic sleeve gastrectomy. This article describes all technical details and difficulties of this operation due to the presence of SIT. When performed by an expert laparoscopic surgeon, however, laparoscopic sleeve gastrectomy appears to be a feasible, effective, and safe procedure to treat morbidly obese patients with SIT.
