Liver and pancreas transplantation in adult donor and recipients with situs inversus totalis: a case series and review of the literature.

backgroundSitus inversus totalis is a rare congenital anomaly characterized by a mirror-image orientation of abdominal, and in some cases, thoracic organs. Here, we report our situs inversus totalis transplantation experience and further review liver transplantations in adult recipients and donors with situs inversus totalis. CASE PRESENTATION: We describe three cases with situs inversus totalis. The first case was liver transplantation in a recipient (a 61-year-old Iranian man) with situs inversus totalis, the second was a liver transplantation from a donor (a 52-year-old Iranian woman) with situs inversus totalis, and finally, for the first time, a simultaneous pancreas and kidney transplantation in a recipient (a 26-year-old Iranian man) with situs inversus totalis. In patient one, hepatectomy could be performed according to the standard method and on the basis of preoperative studies. Hepatic vein and arterial anastomosis were performed as in every other patient without situs inversus totalis. To prevent biliary complications, a Roux-en-Y hepaticojejunostomy was performed. In patient two, implantation time, suprahepatic vein, portal vein, arterial, and biliary reconstruction could be done as in any other case without situs inversus totalis. Plication of the right-sided diaphragm and fixation of the falciform ligament was done for our patient. In patient three, systemic drainage was preferred to portal flow for establishing the outflow drainage of the pancreas compared with otherwise normal patients.

conclusionAlthough situs inversus totalis is a rare condition, our reported techniques are suitable, considering advantages such as easier accessibility, more acceptable placement of the implanted organs regarding vascular variations, and the appropriate location of the allograft in the proximity of other organs.
