Liver Transplantation for Polycystic Liver Disease

Four female patients with severe complications of polycystic liver disease were treated with liver replacement; two patients were also given kidneys from their liver donors. All four of the patients were suffering from extreme fatigue. Three of the recipients have survived for 8, 11, and 60 months with normal liver function and present good health. The fourth patient recovered from a liver-kidney transplantation, but 5 months later, fulminant hepatic failure developed in this patient due to hepatitis B virus, and she died despite emergency hepatic retransplantation. © 1990, American Medical Association.

Surgical technique of orthotopic liver transplantation

Athough significant strides have been made in the surgical technique of orthotopic liver transplantation, numerous problems and nuisances are still encountered. Further surgical refinements will certainly evolve. The development of better preservation techniques, the use of intraoperative flowmeters, and the availability of new technologies, such as an artificial liver, should impact and advance the techniques of liver transplantation significantly and improve the overall results even further

Treatment of upper abdominal malignancies with organ cluster procedures

Upper abdominal exenteration for upper abdominal malignancies was carried out in 15 patients with removal of the liver, spleen, pancreas, duodenum, all or part of the stomach, proximal jejunum and ascending and transverse colon. Organ replacement was with the liver, pancreas and duodenum plus, in some cases, a short segment of jejunum. Eleven of the 15 patients survived for more than 4 months; 2 died, after 6 1/2 and 10 months, of recurrent tumor. Of the 9 patients who are surviving after 6 1/2 to 14 months, recurrent tumor is suspected in only 1 and proven in none. Four patients with sarcomas and carcinoid tumors (2 each) have had no recurrences. The other 5 survivors had duct cell cancers (3 examples), a cholangiocarcinoma (1 example), and a hepatoma (1 example). The experience so far supports further cautious trials with this drastic cancer operation

Decreased incidence of viral infections in liver transplant recipients - Possible effects of FK506?

Cytomegalovirus (CMV) is a major infectious complication of organ transplantation and its incidence is influenced by the type and intensity of immunosuppressive therapy employed. Using a new immunosuppressive agent FK506, CMV infection was observed in 30% and CMV disease in 15% of the 26 liver transplant recipients. Delayed onset of CMV disease was noted; the mean time to the occurrence of CMV disease being 137 days posttransplantation. No graft loss or mortality could be attributed to CMV infection. Mucocutaneous herpes simplex virus (HSV) infections were encountered in 19% of the patients, while no disease could be attributed to varicella zoster virus or Epstein-Barr virus (EBV). The contribution of FK506 to a decrease in viral morbidity and associated mortality bears further investigation. © 1994 Plenum Publishing Corporation

A high incidence of native portal vein thrombosis in veterans undergoing liver transplantation

The incidence of native portal vein thrombosis (PVT) in liver transplant recipients has been reported to range from 2.1 to 13.8%. We have identified an inordinately high incidence of PVT in a consecutive series of U.S. veterans receiving liver transplants. Between October 1989 and February 1994, 88 consecutive U.S. veterans received 99 orthotopic liver transplants under primary Tacrolimus (Prograf, formerly FK506) based immunosuppression. A number of clinical features were examined in an effort to identify risk factors for PVT and outcome was compared to patients without PVT. Native PVT was present in 23/88 (26%) patients. All of these patients were male U.S. veterans with a mean age of 47 years. When compared to the 65 patients without PVT, we found no significant difference with respect to underlying liver disease, age, Childs-Pugh score (mean = 12), UNOS status as defined prior to April 1995 (95% UNOS 3 or 4), previous abdominal surgery, or liver volume. Median blood loss for patients with PVT (21 units of packed red blood cells) was greater than for those without PVT (14 units, P = 0.04). Portal thrombectomy was performed in 11 patients, 11 patients required mesoportal jump grafts, and 1 patient had an interposition graft. Standard veno-venous bypass was used in 10 patients with single bypass utilized for the remainder. Actuarial patient survival for all patients at 1, 2, and 4 years was 88, 85, and 79%, respectively. There was no significant difference in patients with or without PVT. Patients with PVT had poorer graft survival than patients without PVT (86% vs 65%, 1 year; 81% vs 65%, 2 years; 81% vs 61%, 4 years; P = 0.03); however, this was not related to technical problems with the portal venous inflow. PVT occurred in 26% of U.S. veterans undergoing liver transplantation. These patients bad significantly higher operative blood loss and poorer graft survival. The high incidence of postnecrotic cirrhosis in a predominantly male group of patients with advanced disease, as is evident by the high mean Childs-Pugh score and UNOS status, perhaps accounts for our observations
