Case report: laparoscopic cholecystectomy in situs viscerum inversus.

Situs viscerum inversus is a rare condition, in which the organs are transposed from their normal location in the opposite side of the body. The inversion of L-R asymmetry may be complete (SVI totalis) or partial (SVI partialis), whereby transposition is confined to either the abdominal or thoracic viscera. The authors report a case of videolaparocholecystectomy for cholelithiasis successfully performed on a 41-year-old Caucasian woman with situs viscerum inversus totalis. The patient was discharged on the 2nd postoperative day. The symptomatology disappeared right after the intervention, and still now, after a follow-up of six months, is absent. The procedure was safely performed on the patient with no particular difficulties, except for the reverse position of the angle between the operating and exposing trocars, which led to a difficult approach to the Calot triangle when using the right hand of the surgeon.
