With advances in transplantation, multiorgan transplantation has become a treatment of choice for end-stage organ failure which can not be reversed with other modalities. In 1984, the first case of combined liver and kidney transplantation was introduced by Witts at Innsbruck University Hospital in a 30-year-old man with HBsAg positive cirrhosis. He survived more than 9 years. Since then, an increasing number of such combined transplantation has been performed. But in Asia, this technique has not been put into clinical practice yet. We report such a case below.
A 52-year-old woman was admitted to our hospital with fatigue, jaundice and severe abdominal pain. She suffered from congenital polycystic liver and kidney disease at 40 years of age. Two weeks before her admission, she underwent laporatory in a local hospital for unbearable abdominal pain. She was found to have anemia and jaundice in physical examination. She had an enormous liver extending to pelvic cavity with an enlarged spleen. Biochemical tests showed hemoglobin 103 g/L, WBC 3.2 × 109/L, platelet 7.4 × 109/L, serum total bilirubin 42.7 μmol/L, albumin 30 g/L, creatine 62 μmol/L, BUN-8.5 μmol/L and prothrombin time 18 seconds (control 12 seconds). The renogram indicated that her renal function had been slightly damaged. Two weeks after her admission, she received combined liver and kidney transplantation.
The donated liver and kidney were harvested using the rapid multiple organs harvesting technique. Both organs were flushed in situ and then cold preserved in the Winsconson University solution. Lym-phocyte cross-matching was negative and the panel reactive antibody (PRA) was 8%.
The liver was transplanted orthotopically using veno-venous bypass during anhep atic phase. Following implantation of the liver, the kidney was placed intrapert ioneally into the right iliac fossa after 12.5 h of cold ischemia. Bile was produced promptly, indicating immediate graft function. The kidney assumed normal color and consistency after revascu-larization and produced copious amounts of urine. The total operative blood loss was 3500 mL, and 2800 mL blood products were infused. Immunosup-pressive regimen including cyclosporine A, 2 mg/kg per day intravenously, and methylpredisolone (starting with 1 g per day and tapering to 10 mg daily) was given.
The early postopertive course was uneventful. The patient was discharged two months after combined liver and kidney transplantation. Six months after transplantation, however, she developed jaundice though her general condition was good. Following the jaundice period, liver function began to show signs of deterioration. The biliary sludge was diag-nosed. She was reoperated due to biliary obstruction. The biliary sludge which was 2.0 cm × 0.5 cm in size located in the middle portion of common bile duct. The patient was soon recovered from the sec-ond operation and discharged on the 20th day with nearly normal liverfunction. She is doing well and is in good health.
The high success rate achieved with single organ transplantation has stimulated the assumption of double organ transplantation for patients with complex multiorgan failure. The development of new immunosuppressive agents and improved surgical approaches as well as sophisticated postoperative man-agement make assumption become clinical practice.
The main concern in combined liver and kidney transplantation is the selection of candidates. According to Margreiter, the indications for combined liver-kidney transplantation are divided into three categories: (1) Disease affecting both organs, such as autosomal dominant polycystic disease. (2) Renald isorders with liver involvement or liver disorders with renal involvement, inclu ding primary type I hyperoxaluria, type I glycogen storage disease, cholesterol acyltransferase deficiency, etc. (3) Separate diseases of both organs. This category consisting of patients on hemodialysis with liver disease and patients with end-stage liver disease and renal function impairment other than hepatorenal syn-drome is the main indication for combined liver and kidney transplantation.
Autosomal dominant polycystic kidney disease is often present in newborns, but dose not become clinically evident until adulthood. It is often associated with liver cysts which may reach enormous size (in our case, it weighs 5.0 kg) and can therefore be extremely disabling considering both the rigors of renal ischemia during transplantation and nephro-toxic effects of cyclosporine A, and some necessitating antibiotics may worsen the previously impaired renal function and lead to postoperative renal failure. We treated the patient with combined liver-kidney transplantation.
The surgical technique of combined liver-kidney transplantation was exactly the same as for transplantation of the liver or the kidney alone. For the reason that liver is more subject to cold ischemia damage than kidney, the liver is gener ally implant-ed prior to the kidney. In case a venovenous bypass should be needed, the axilla and thigh, preferentially on the left side, must be prepared. Because of the poor coagulation status of the recipient, heparin may not be required for prevention of clotting.
A protective role of the liver allografts in the survival of other solid organ transplants has been noted, but the exact mechanism of this phenomenon has not been elucidated. The liver has the potential to protect the other organs immunologically. The efficacy of simultaneous liver-kidney transplantation in the prevention of hyperacute renal rejection in patients with reformed anti-HLA lymphocytotoxic antibodies is also demonstrated in clinical practice. However, these observations have been challanged by reports documenting hyperacute rejection of kid ney or/and liver allografts when the roles of ABO matching and donor/recipient crossmatching have been violated[4-5]. Although our patient did not ex-perience any rejection and showed some protection of the transplanted kidney by the liver graft, we be-lieve that careful selection of suitable donor with HLA typing crossmatching and PRA test are essen-tial to success in combined liver-kidney transplantation.
