Experience with domino or sequential liver transplantation in familial patients with amyloid polyneuropathy

Expanding the living donor pool using domino liver transplantation: a systematic review

INTRODUCTION

To this day, a discrepancy exists between donor liver demand and supply. Domino liver transplantation (DLT) can contribute to increasing the number of donor livers available for transplantation.

METHODS

The design of this systematic review was based on the Preferred Reporting Items for Systematic Reviews (PRISMA). A qualitative analysis of included studies was performed. Primary outcomes were mortality and peri- and postoperative complications related to DLT.

RESULTS

Twelve studies met the inclusion criteria. All included studies showed that DLT outcomes were comparable to outcomes of deceased donor liver transplantation (DDLT) in terms of mortality and complications. One-year patient survival rate ranged from 66.7% to 100%. Re-transplantation rate varied from 0 to 12.5%. Most frequent complications were related to biliary (3.7%-37.5%), hepatic artery (1.6%-9.1%), portal vein (12.5-33.3%) and hepatic vein events (1.6%), recurrence of domino donor disease (3.3%-17.4%) and graft rejection (16.7%-37.7%). The quality of the evidence was rated as moderate according to the Newcastle-Ottawa scale (NOS).

CONCLUSION

DLT outcomes were similar to DDLT in terms of mortality and complications. Even though DLT will not solve the entire problem of organ shortage, transplant programs should always consider using this tool to maximize the availability of liver grafts.

Domino liver transplantation: indications, techniques, and outcomes

The long-term shortage of livers available for transplantation has spurred the development of many strategies to bolster the donor organ supply. One particularly innovative strategy is domino liver transplantation in which a select group of liver transplant recipients can donate their explanted native livers for use as liver grafts in other patients. Several hereditary metabolic diseases (such as familial amyloid polyneuropathy, maple syrup urine disease, and familial hypercholesterolemia) are caused by aberrant or deficient protein production in the liver, and these conditions can be cured with an orthotopic liver transplant. Although their native livers eventually caused severe systemic disease in these patients, these livers are otherwise structurally and functionally normal, and they have been used successfully in domino liver transplants for the past 15 years. This article will review the indications for donating or receiving a domino liver transplant, the surgical techniques necessary to perform these transplants, as well as the recently revealed long-term outcomes and risks of domino transplantation.

Milestones in the evolution of hepatic surgery

This paper describes the rapid evolution of modern liver surgery, starting in the middle of the twentieth century. Claude Couinaud studied and described the segmental anatomy of the liver, Thomas Starzl performed the first liver transplantations, and Henri Bismuth introduced the concept of anatomical resections. Hepatic surgery has developed significantly since those early days. To date, innovative techniques are applied, using cutting-edge technologies: Intraoperative ultrasound, techniques of vascular exclusion of the liver, new devices for performing homeostasis and dissection, laparoscopy for resections, and new drugs that allow the resection of previously unresectable tumors. The next stage in liver surgery will probably be the implementation of a multidisciplinary holistic approach to the liver-diseased patient that will ensure the best and most efficient treatments in the future.

Metabolic storage diseases: amyloidosis

This article provides an overview of the current concepts in pathogenesis, epidemiology, clinical significance, and treatment options for amyloidosis. Emphasis is given to hepatic amyloidosis, which ranges from a clinically insignificant histologic curiosity to a harbinger of widespread disease accompanied by a poor prognosis. Clinical characteristics and clues to the diagnosis are discussed as well as the importance of histologic confirmation and the controversy surrounding liver biopsy.

Techniques of orthotopic liver transplantation

BACKGROUND

Throughout the history of liver transplantation many improvements have been made in the field of surgical technique. It is beyond the scope of this paper to review all aspects of surgical technique in liver transplantation; thus, in this review we focus on the description of our current technique in most cases, which is orthotopic liver transplantation with preservation of the inferior vena cava and temporary portocaval shunt. We advocate this technique because it has been demonstrated that it achieves better haemodynamic stability during the anhepatic phase, transfusion can be reduced and renal function is improved. The different options for vascular anastomoses are described, particularly the options for arterial anastomoses in case of finding a non-adequate recipient hepatic artery. Technical possibilities for patients with preoperative portal vein thrombosis and the procedure in case of domino or sequential liver transplantation are further explained.
