Abstract
Emergency liver transplantation is the treatment of choice for the most severe forms of fulminant hepatitis B. Auxiliary liver transplantation is an attractive alternative, offering the possibility of regeneration and discontinuation of immunosuppression. However, the use of auxiliary transplantation for fulminant hepatitis B is controversial because the remnant part of the native liver could be the source of recurrence of HBV infection. We report the results of auxiliary liver transplantation in six patients with fulminant hepatitis B. Postoperatively, all patients received gancyclovir and anti-hepatitis B surface immune globulins. Graft function has been satisfactory in all cases and all patients had rapid neurologic improvement. One patient died with a functional graft because of disseminated aspergillosis on postoperative day 17. The remaining 5 patients are currently alive. The 4 patients with more than 1-year follow-up had complete regeneration of the native liver and are free of immunosuppression. None of these patients had recurrence of hepatitis B. These results suggest that the use of an auxiliary graft is a safe alternative in selected patients with fulminant hepatitis B. Regeneration of the native liver, even if slow, seems to occur in most cases, allowing discontinuation of immunosuppression, which is a major advantage over conventional transplantation. Finally, the remnant part of the native liver does not compromise immunization against HBV.

Abstract
Following a heterotopic auxiliary liver transplantation, commonly used measurements are either invasive or non-indicative of individual viability of the coexisting engrafted and native livers. Magnetic resonance imaging (MRI) was therefore tested for its potential to monitor the post-transplant hepatic viability in a rat model. Thirteen Wistar rats were systematically evaluated with MRI and serum biochemical liver parameters. Post-transplant complications and the causes of animal death were identified by autopsy and histo-pathological examinations. The data of the healthy survivors were compared with those of the rats that developed complications. On MRI, the hepatic complications could be depicted in the individual livers. A specific pattern of signal evolution was found in the livers of the healthy survivors: the mean T1 relaxation times of the engrafted livers increased immediately after transplantation (476 +/- 64 ms, mean +/- standard deviation, pre-operative; 730 +/- 48 ms, week 1) and then declined steadily to a 3 month value of 489 +/- 246 ms, while, following a transient first rise (476 +/- 64 ms, pre-operative; 589 +/- 28 ms, week 1), the mean T1 value of the native livers increased again 4 weeks after surgery and reached a 3 month value of 859 +/- 43 ms. However, in the rats with various complications, the mean T1 relaxation times of the engrafted livers continued to increase throughout the first post-operative month (760 +/- 48 ms, week 1; 922 +/- 76 ms, week 4), while that of the native liver only varied mildly (546 +/- 25 ms, week 1; 473 +/- 25 ms, week 4). After the first post-transplant week, the healthy engrafted livers could already be distinguished from those with complications by a significant decrease in T1 relaxation times. These data suggest that, besides demonstrating major complications, MRI may allow one to monitor the viability of each liver by analysing the relative signal intensity and T1 relaxation times after a heterotopic auxiliary liver transplantation.

Abstract
Combined liver-intestine transplantation is an evolving procedure, and auxiliary liver transplantation has several advantages over standard orthotopic liver transplantation. We present a new model of combined intestine-auxiliary liver transplantation in rats. Total small bowel and 60% liver were harvested en bloc. An aortic segment that contained the celiac axis and superior mesenteric artery ensured blood supply to the graft. Venous drainage of the grafted intestine was achieved via the intact portal vein of the graft. The infrahepatic vena cava was cut at different levels during the modification period and at the oblique level of the left renal vein in consecutive series. Revascularization was accomplished by end-to-side anastomosis of the aorta and of the infrahepatic vena cava. The recipient small bowel was resected and the intestine continuity restored by anastomosis. Total operation time averaged 130 min. The overall survival rate of 3 months in the consecutive series was 80% (16/20). Exploratory laparatomy and histologic study in 3 rats on 90 days after transplantation revealed normal and viable grafts. Liver function was normal and both grafted liver and intestine showed normal histologic architectures in 5 rats observed for 12 months after transplantation. The present model is reproducible and allows preclinical research on several aspects of experimental combined intestine-auxiliary liver transplantation.

Abstract
Auxiliary liver transplantation for patients with fulminant hepatic failure supports the patient's failing liver for a period of time until the native liver (NL) has recovered and immunosuppression can be withdrawn. Auxiliary heterotopic liver transplantation (AHLT) with portal vein arterialization (PVA) has several advantages over auxiliary orthotopic liver transplantation: NL resection is not required, and the hepatic hilum is left untouched; thus, the chances of liver regeneration are optimal. The successful application of emergency AHLT with PVA in a young patient who developed toxic fulminant hepatic failure caused by tuberculostatic drugs is described. Two and one-half months after the procedure, the NL had completely regenerated; the graft was removed, and immunosuppression was suspended.

Abstract
Functional competition has been shown to lead to a detrimental outcome in auxiliary liver transplantation. We evaluated the interaction in auxiliary partial orthotopic liver transplantation between the native liver and the graft in terms of portal flow and regeneration. The need for diversion of the portal flow to the graft was also assessed. Reduced-size liver grafts were transplanted orthotopically after partial hepatectomy in beagles. There were two groups: the preserved group, where portal inflow to the native liver was preserved, and the ligated group, where it was interrupted. Portal flow was measured serially and liver regeneration was evaluated on postoperative day 5. Functional competition was not observed in the preserved group. On the other hand, ligation of the native liver portal vein had no obviously detrimental effects on the remnant native liver. This leads to the conclusion that the portal vein to the native liver can be safely ligated to prevent functional competition.

Abstract
In the rat model of heterotopic auxiliary liver transplantation, the coexistence of the engrafted liver and the recipient's native liver makes it difficult to evaluate the posttransplant graft viability. In this study, auxiliary liver transplantation was performed in Wistar rats, in which the recipient's native liver was handicapped with a 68% partial hepatectomy and a common bile duct ligation. Serum biochemistry of the liver was analyzed and compared with that of the selected control group. The surgical handicap of the liver showed severe damaging effects: the handicapped native livers appeared atrophic at autopsy, and no long-term animal survival could be achieved without an auxiliary liver transplantation. As the engrafted liver corrected the cholestasis of the handicapped native liver, significant differences of serum biochemistry were found between the transplanted group and the control group: for bilirubin concentration and gamma glutamyl transferase activity from postoperative day 3 to 28 (p < .05); for alkaline phosphatase on days 3, 7, 14, and 28 (p < .05); for alanine aminotransferase activity on days 3 and 14 (p < .05); and for aspartate aminotransferase activity on day 14 (p < .05). The efficiency to induce hepatic failure and to hamper its regeneration capacity in the native liver makes animal survival and liver biology as reliable parameters to evaluate the posttransplant graft viability in this rat model.

Abstract
BACKGROUND/PURPOSE Auxiliary liver transplantation is an attractive alternative for orthotopic liver transplantation in patients with certain inborn errors of metabolism of the liver in which complete resection of the liver is unnecessary or even contraindicated. Because in these diseases portal hypertension is mostly absent, finding a balance in portal blood distribution between native liver and graft is complicated. The objective of this study was to investigate requirements for long-term (180 days) graft survival in auxiliary partial heterotopic liver transplantation (APHLT) in a dog model. METHODS A metabolic defect was corrected in 26 dalmation dogs with a 60% beagle heterotopic auxiliary liver graft. Four groups of different portal inflow were studied. In the ligation group the portal vein to the host liver was ligated. In the split-flow group graft and host liver received separate portal inflow. In the banding group the distribution of the portal flow was regulated with an adjustable strapband and in the free-flow group the portal blood was allowed to flow randomly to host or graft liver. RESULTS Metabolic correction increased in all groups after transplantation from 0.19 +/- 0.02 to 0.70 +/- 0.05 (P< .0001) but remained significantly better in the ligation and split-flow groups (graft survival, 135 +/- 27 and 144 +/- 31 days). In the banding group metabolic correction decreased significantly after 70 days, and although the grafts kept some function for 155 +/- 14 days, in 4 of 6 dogs portal thrombosis was found. In the free-flow group, competition for the portal blood led to reduced correction within 12 days and total loss of function in 96 +/- 14 days. Graft function also was assessed with technetium (Tc) 99m dimethyl-iminodiacetic acid uptake. A good linear association between HIDA uptake and metabolic correction was observed (r = 0.74; P < .0005). Grafts that contributed more than 15% to the total uptake of HIDA showed biochemical correction. This indicates a critical graft mass of about 15% to 20% of the hepatocyte volume to correct this metabolic defect. CONCLUSION Auxiliary partial heterotopic liver transplantation can be a valuable alternative treatment for inborn errors of hepatic metabolism if the native liver and the graft receive separate portal blood inflow.

Abstract
BACKGROUND/AIMS/METHODS We report 1-year results after auxiliary liver transplantation for acute liver failure in a cohort of 47 patients transplanted in 12 European centers as compared with those of 384 consecutive patients undergoing orthotopic liver transplantation for acute liver failure in the Eurotransplant area. RESULTS One-year patient survival resp. retransplant-free patient survival did not differ between orthotopic (61%, 232/384 resp. 52%, 200/384) and auxiliary liver transplantation (62%, 29/47 resp. 53%, 25/47). One-year patient survival resp. retransplant-free patient survival after auxiliary partial orthotopic liver transplantation was 71% (25/35) resp. 60% (21/35), not significantly different from orthotopic liver transplantation (61%, 232/384 resp. 52%, 200/384), while both transplantation techniques had better 1-year patient survival resp. retransplant-free patient survival than after heterotopic auxiliary liver transplantation (33%, 4/12) (p < 0.05). Primary nonfunction was more frequent after heterotopic auxiliary liver transplantation (3/12, 25%) than after orthotopic liver transplantation (21/384, 5.5%), while the incidence did not differ between orthotopic liver transplantation and auxiliary partial orthotopic liver transplantation (3/35, 8.5%). Portal vein thrombosis was more frequent after both heterotopic auxiliary liver transplantation (5/12, 42%) and auxiliary partial orthotopic liver transplantation (5/35, 14%) than after orthotopic liver transplantation (2/384, 0.5%) (p < 0.001). Of the patients, 65% (17/26) surviving auxiliary liver transplantation for 1 year without retransplantation by orthotopic liver transplantation were free of immunosuppression within 1 year, compared with none of the patients transplanted by orthotopic liver transplantation (p < 0.01). CONCLUSIONS Auxiliary liver transplantation, especially auxiliary partial orthotopic liver transplantation, offers an advantage over orthotopic liver transplantation in acute liver failure in terms of a chance of a life free of immunosuppression, apparently without jeopardizing chances of survival. Reduction of the incidence of primary nonfunction and vascular complications should be a focus of research in auxiliary liver transplantation. These findings need to be confirmed in a prospective study.

Abstract
BACKGROUND Auxiliary liver transplantation has several advantages over standard orthotopic liver transplantation. However, functional competition has been reported even in auxiliary partial orthotopic liver transplantation (APOLT). We evaluated herein the interaction in APOLT between the native liver and the graft in terms of portal blood flow and regeneration. The need for diversion of the portal blood flow to the graft was also assessed. METHODS A total of 15 patients received APOLT from living donors. Portal blood flow to the native liver was preserved in 6 patients, and the portal vein to the native liver was preemptively transected at the time of transplantation in 9 patients. RESULTS Of the patients with preservation of the portal blood flow to the native liver, two showed inadequate graft portal blood flow just after operation, and in the other three patients the graft portal blood flow decreased or the graft atrophied after deterioration of the graft function. In the patients with preemptive transection of the portal vein to the native liver, optimal graft portal blood flow was obtained, and the native liver, supplied only by arterial inflow, supported a small-for-size graft until the graft regenerated. The damage to the native liver was minimal. CONCLUSIONS Functional competition may occur in APOLT with preservation of the portal blood flow to the native liver, whereas preemptive transection of the native liver portal vein is a safe procedure and effectively prevents the portal steal phenomenon.

Abstract
Auxiliary liver transplantation (ALT), retaining in place the liver of the recipient, has been proposed as an alternative to liver replacement in patients with fulminant hepatic failure (FHF). Hepatobiliary scintigraphy (HS) has proved a unique tool for the separate assessment of graft and native liver function. Forty-eight HS scans were performed, following the injection of technetium-99m trimethyl-bromo-imino-diacetic acid, in six patients who underwent ALT for FHF. Quantitative parameters were derived from the time-activity curves of both the graft and the native liver. The function of the graft remained normal as long as the patients remained under immunosuppressive therapy (IST). The function of the native liver was almost completely absent in the 1st month in five patients, but it improved gradually in four of them. IST was then decreased in four patients and finally withdrawn in three. Spontaneous graft atrophy occurred in two patients and the graft was removed in two. All of the patients in whom IST was reduced had a normal global hepatic function and selective uptake (RU) >30% at that time. In ALT patients with FHF, HS can distinguish non-invasively the functional performance of both the donor and the recipient liver and its evolution with time.

Abstract
OBJECTIVE The authors objective is to report their experience with auxiliary partial orthotopic liver transplantation in fulminant hepatitis (FH) and to discuss the principles that may help in its safe application. SUMMARY BACKGROUND DATA Auxiliary partial orthotopic liver transplantation is an attractive therapeutic method in FH because it provides hepatic function, whereas the remaining native liver is given the possibility to recover. Despite early encouraging reports, its place in the treatment of FH remains to be defined. METHODS Evaluation of 5 cases of FH treated with auxiliary partial orthotopic liver transplantation from a collective of 22 transplantations for 35 cases of FH referred to the authors' center from January 1994 to November 1995. The grafts were one left lobe, two left livers, and two right livers. RESULTS The native liver regenerated in three patients: one with Reye's syndrome who died of irreversible neurologic damage, one with FH caused by the hepatitis B virus who is alive 20 months after ABO incompatible graft removal, and one with FH caused by the hepatitis A virus who had her graft removed at 4 months. In two patients, regeneration did not occur: one with drug-induced FH who died of sepsis 3 months after surgery and one with FH of unknown origin who was retransplanted with a standard liver transplantation at 4 months for uncontrollable biliary rejection of an ABO incompatible graft (alive at 10 months). Two of the three patients who survived suffered severe neurologic complications. CONCLUSIONS Auxiliary partial orthotopic liver transplantation is an attractive treatment for FH, especially in the presence of good prognostic factors for native liver regeneration: a young patient, rapid onset of the disease, and viral hepatitis. It should be considered cautiously in patients with advanced encephalopathy. By providing a smaller mass of liver tissue than with standard orthotopic liver transplantation, and as a more complex operative procedure, auxiliary partial orthotopic liver transplantation may not be as effective in arresting the progression of neurologic damage.
