Abstract
Sequential or domino liver transplantation is a well-established procedure for patients with familial amyloidotic polyneuropathy (FAP). Donation for domino liver transplantation imposed the resection of the inferior vena cava along with the liver, requiring complete suprarenal vena cava clamping and usually the use of venovenous bypass. We describe a successful case in which it was possible to perform the FAP hepatectomy by the piggyback technique.

Abstract
INTRODUCTION We compared early results of orthotopic liver transplantation (OLT) in adults using the classic versus piggyback technique of inferior vena cava anastomosis. PATIENTS AND METHODS We analyzed 100 consecutive patients who underwent OLT from 2000 to 2003. Group A included 50 patients operated with the classic technique with venovenous extracorporeal bypass, and group B, 50 patients with the piggyback technique. The age range of the patients in group A was 21 to 63 years (mean, 43.5 years) and in group B, 20 to 65 years (mean, 46 years). The gender F/M distribution in group A was 24/26 and in group B, 28/22. The indications for OLT were acute hepatic failure (8%), chronic liver insufficiency (77%), liver tumors (8%), metabolic diseases (5%), and Budd-Chiari syndrome (2%). The degrees of liver insufficiency evaluated according to the Child classification were A, 18; B, 52; and C, 30 patients. The urgency for OLT on the United Network for Organ Sharing (UNOS) scale was UNOS 1-group A, 2 patients; group B, 7 patients; UNOS 2a-group A, 7 patients; group B, 6 patients; UNOS 2b-group A, 29 patients; group B, 30 patients; UNOS 3-group A, 12 patients; group B, 7 patients. RESULTS The average cold ischemia time in group A was 530 minutes and in group B, 515 minutes. The average results on the 10th postoperative day: aspartate transaminase (AST)-group A, 52.5 U/L; group B, 54.5 U/L; alanine transaminase (ALT)-group A, 131.5 U/L; group B, 153 U/L; gamma glutyl transpeptidase (GGTP)-group A, 299 U/L; group B, 285.5 U/L; alkaline phosphatase (ALP)-group A, 164 U/L; group B, 150.5 U/L; bilirubin-group A, 4.37 mg%; group B, 2.71 mg%; activated partial thromboplastin time (APTT)-group A, 37.6 seconds; group B, 34.8 seconds; platelets (PLT)-group A, 167 10(2)/mm(2); group B, 171 10(2)/mm(2). The incidence of postoperative complications was 36% in group A; it was 30% in group B. The mean hospitalization times in the surgical department were 17 days in group A and 16 days in group B. CONCLUSIONS The early results, morbidity and mortality with both applied techniques were similar. Individualization in qualifying the patients for a given operative technique is important. The lower complication rate and reduced treatment cost of the piggyback technique group suggested advantages of this technique when compared with the classical OLT technique.

Abstract
Reliable monitoring enabling evaluation of graft function is crucial after living-donor liver transplantation (LDLT). A method to identify poor graft function at an early postoperative period would allow opportune intensive clinical management to bring about further improvements in LDLT outcomes. This study assessed the reliability of the indocyanine green (ICG) elimination rate constant (K(ICG)) value as an estimator of graft function and determined the actual temporal changes of K(ICG) after LDLT. K(ICG) values were measured using a noninvasive method in 30 adult recipients up to 28 days after LDLT. The receptor index (LHL15) based on liver scintigraphy, and graft parenchymal damage score based on histopathological findings were evaluated after LDLT and correlated well with simultaneous K(ICG). Thus, K(ICG) measured by noninvasive method was confirmed as accurately evaluating graft function. Changes of K(ICG) after LDLT in recipients with good graft function were maintained, after some falls in the early periods, and had a significant difference compared with those for recipients without good graft function; moreover, there were already significant differences in K(ICG) 24 hours after LDLT. Mean transit time reflecting systemic hemodynamics revealed that recipients without good outcomes fell into an unstable systemic hemodynamic state, and effective hepatic blood flow has a large influence on liver regeneration after LDLT. In conclusion, we suggested that K(ICG) values can predict clinical outcomes at the early postoperative period after LDLT by sharply reflecting the influence of systemic dynamics on splanchnic circulation.

Abstract
Preservation of the caval vein during liver transplantation (OLT) has gained wide acceptance but portosystemic bypass or temporary portocaval shunt is still believed to be indicated in patients with fulminant hepatic failure. Herein we have described our initial experience with piggyback OLT without venovenous bypass and without portocaval shunting in five such patients. Division of the portal vein was always delayed until the native liver was completely dissected off the caval vein. The donor hepatic artery was anastomosed to the recipient aorta via an iliac interposition graft placed in the supraceliac position in two and at an infrarenal site in three patients. The ahepatic phase urinary output was low in the two patients in whom we applied supraceliac cross-clamping of the aorta. The mean ahepatic phase was 53 (45 to 67) minutes in four recipients who remained hemodynamically stable throughout surgery and prolonged to 5 hours in one patient due to a complicated supraceliac aortic anastomosis. Its repair resulted in hemodynamic instability, multiorgan failure, and death at 4 days following OLT. Four (80%) patients are alive in good condition with normal liver function after a mean of 12 (5 to 25) months of follow-up. In summary, liver transplantation for fulminant hepatic failure may be safely performed without venovenous bypass and without temporary portocaval shunting if the ahepatic phase is minimized and portal flow to the liver maintained up to the moment of hepatic excision. Arterial anastomosis with the supraceliac aorta prolongs the ahepatic phase and may impair kidney function: therefore, it should be avoided in these patients.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) in adult patients has traditionally been performed using conventional caval reconstruction technique (CV) with veno-venous bypass. Recently, the piggyback technique (PB) without veno-venous bypass has begun to be widely used. The aim of this study was to assess the effect of routine use of PB on OLTs in adult patients. PATIENTS AND METHODS A retrospective analysis was undertaken of 1067 orthotopic cadaveric whole liver transplantations in adult patients treated between June 1994 and July 2001. PB was used as the routine procedure. Patient demographics, factors including cold ischemia time (CIT), warm ischemia time (WIT), operative time, transfusions, blood loss, and postoperative results were assessed. The effects of clinical factors on graft survival were assessed by univariate and multivariate analyses.In all, 918 transplantations (86%) were performed with PB. Blood transfusion, WIT, and usage of veno-venous bypass were less with PB. Seventy-five (8.3%) cases with PB had refractory ascites following OLT (p=NS). Five venous outflow stenosis cases (0.54%) with PB were noted (p=NS). The liver and renal function during the postoperative periods was similar. Overall 1-, 3-, and 5-year patient survival rates were 85%, 78%, and 72% with PB. Univariate analysis showed that cava reconstruction method, CIT, WIT, amount of transfusion, length of hospital stay, donor age, and tumor presence were significant factors influencing graft survival. Multivariate analysis further reinforced the fact that CIT, donor age, amount of transfusion, and hospital stay were prognostic factors for graft survival. CONCLUSIONS PB can be performed safely in the majority of adult OLTs. Results of OLT with PB are as same as for CV. Liver function, renal function, morbidity, mortality, and patient and graft survival are similar to CV. However, amount of transfusion, WIT, and use of veno-venous bypass are less with PB.

Abstract
OBJETIVO: Apresentar os resultados iniciais de um serviço de transplante hepático que utiliza a técnica piggyback como padrão. MÉTODO: Análise retrospectiva de 19 transplantes de fígado enfatizando as complicações pós-operatórias e a taxa de sobrevida dos pacientes. A indicação mais freqüente de transplante foi cirrose pelo vírus C em nove pacientes (47%). De acordo com a gravidade da doença hepática, nove casos (47,3%) foram classificados como Child C e oito (42%) como B. Os dois casos restantes foram hepatite fulminante e trombose tardia de artéria hepática. RESULTADOS: Foram realizados 19 transplantes em 18 pacientes com doador cadáver empregando a técnica com preservação da veia cava (piggyback) em 100% dos casos. A indicação mais freqüente de transplante foi cirrose pelo virus C em nove pacientes (47%). De acordo com a gravidade da doença hepática nove casos (47,3%) foram classificados como Child C e oito (42%) como B. Os dois casos restantes foram hepatite fulminante e trombose tardia de artéria hepática. A idade média foi de 45,6 anos. O tempo de isquemia fria do enxerto foi em média de 7,8 horas e a permanência hospitalar média de 18 dias. As complicações mais freqüentes foram as biliares (21%), sendo que três pacientes necessitaram de reoperação e um foi tratado por endoscopia. Houve dois casos de trombose tardia de artéria hepática, sendo um deles tratado por retransplante. Houve um óbito (5,2%) no 8o dia de pós-operatório ocasionado por disfunção primária do enxerto. A sobrevida inicial maior que 30 dias foi de 94,7%. CONCLUSÕES: É possível ter bons resultados no início de um programa de transplante de fígado, desde que haja uma técnica padronizada e uma equipe bem treinada e envolvida com as complicações pós-operatórias.

Abstract
The aim of this study is to analyse a single centre's experience with two techniques of liver transplantation (OLT), conventional (CON-OLT) and piggyback (PB-ES), and to compare outcome in terms of survival, morbidity, mortality and post-operative liver function as well as operative characteristics. A consecutive series (1994-2000) of 167 adult primary OLT were analysed. Ninety-six patients had CON-OLT and 71 patients had PB-ES. In PB-ES group two revascularization protocols were used. In the first protocol reperfusion of the graft was performed first via the portal vein followed by the arterial anastomosis (PB-seq). In the second protocol the graft was reperfused simultaneously via portal vein and hepatic artery (PB-sim). One-, 3- and 5-yr patient survival in the CON-OLT and PB-ES groups were 90, 83 and 80%, and 83, 78 and 78%, respectively (p = ns). Graft survival at the same time points was 81, 73 and 69%, and 78, 69 and 65%, respectively (p = ns). Apart from the higher number of patients with cholangitis and sepsis in CON-OLT group, morbidity, retransplantation rate and post-operative liver and kidney function were not different between the two groups. The total operation time was not different between both groups (9.4 h in PB-ES vs. 10.0 h in CON-OLT), but in PB-ES group cold and warm ischaemia time (CIT and WIT), revascularization time (REVT), functional and anatomic anhepatic phases (FAHP and AAHP) were significantly shorter (8.9 h vs. 10.7 h, 54 min vs. 63 min, 82 min vs. 114 min, 118 min vs. 160 min and 87 min vs. 114 min, respectively, p < 0.05). RBC use in the PB-ES group was lower compared to the CON-OLT group (4.0 min vs. 10.0 units, p < 0.05). Except for WIT and REVT there were no differences in operative characteristics between PB-Sim and PB-Seq groups. The WIT was significantly longer in PB-Sim group compared with PB-Seq group (64 min vs. 50 min, p < 0.05); however REVT was significantly shorter in PB-Sim group (64 min vs. 97 min, p < 0.05). Results of this study show that both techniques are comparable in survival and morbidity; however PB-ES results in shorter AAHP, FAHP, REVT and WIT as well as less RBC use. In the PB-ES group there seems to be no advantage for any of the revascularization protocols.

Abstract
Venovenous bypass has improved patient survival and decreased morbidity and mortality in the field of orthotopic liver transplantation. The standard at many transplant centers is the use of the internal jugular percutaneous venovenous bypass cannulae (PVVBC) for venous return to the patient. Placement of these large (18F) PVVBC may lead to several complications and requires confirmation before use. Use of transesophageal echocardiography, an effective and rapid method to guide placement of the PVVBC and minimize potential complications associated with insertion of the device, is described.

Abstract
BACKGROUND The original method of liver transplantation (LT) included recipient inferior vena cava (IVC) resection and the use of extracorporeal venovenous bypass (VVB). Refinements in technique permit transplantation to be done with IVC preservation and without VVB use. MATERIAL AND METHODS Between November 1993 and November 2000, 202 consecutive grafts were performed in 188 adults (>/=16 years of age). Twelve patients (6.4%) received two and three retransplants (re-LT). Split grafting was performed 19 times (19 of 202 grafts, 9.4%). Risk factors included United Network of Organ Sharing status I (n=30, 16%), previous right upper abdominal surgery (n=32, 17.1%), caudate lobe encirclement of IVC (n=65, 32.2%), IVC (n=24, 11.9%), and splanchnic venous modification (n=58, 30.9%), transjugular intrahepatic portosystemic stent shunt (n=34, 16.8%), giant (>5 kg) liver tumor (n=6, 3%), septic necrosis of the caudate lobe (n=1, 0.5%), and previous cavocaval (n=13, 6.4%) or classical LT (n=5, 2.5%). RESULTS IVC preservation, avoidance of IVC cross clamping and of VVB use were possible in 98.9%, 93%, and 99.5% of 183 primary LT and in 89.5%, 84.2%, and 89.5% of 19 re-LT. Temporary portocaval shunting was never applied. Perioperative mortality was 1.2%. There was no allotransfusion in 73 (36%) grafts and 45 (22%) patients were immediately extubated. Permanent hepatic vein and caval problems were encountered in three (1.5%) grafts. One patient needed stent placement to treat IVC stenosis. Actual 3- and 12-month patient survival for whole, re-LT, and right-lobe split LT groups were 94.7%, 94.1%, 94.7%, 88.2%, 94.1%, and 89%. Three-month graft survival rates for these groups were 92.6%, 94.7%, and 84.2%. CONCLUSIONS LT with IVC preservation and without VVB use and portocaval shunting is possible in nearly all primary transplants and in the majority of re-LT.

Abstract
OBJETIVO: Apresentar a experiência e enfatizar o aprendizado obtido em um programa incipiente de transplante hepático desenvolvido em Hospital Universitário de Recife-PE. MÉTODO: Foram estudados os primeiros 20 pacientes submetidos a transplante ortotópico de fígado, de maneira simplificada, no período de agosto de 1999 a março de 2002. Foram analisadas as indicações, a reserva funcional hepática pré-operatória, o volume de sangue transfundido, o tempo de isquemia, o tempo de permanência em UTI, a morbidade e a mortalidade. A cirrose por vírus C foi a indicação de transplante em 9 pacientes (45%), seguida de cirrose alcoólica em 7 (35%). Quarenta e cinco por cento dos pacientes foram classificados como CHILD-PUGH A, 35% como B, e apenas 20% como C. RESULTADOS: O tempo de isquemia médio foi de 9h 09' (+ 2h 33'). Foram utilizadas em média 2,88 (+ 2,11) unidades de hemácias. A técnica empregada foi a convencional sem bypass em 90% dos casos e piggyback nos restantes. No pós-operatório, houve um caso de trombose de artéria hepática e outro de veia porta. Oito pacientes apresentaram complicações biliares, todas resolvidas por via endoscópica ou percutânea. A sobrevida global é de 100%, no período de seguimento de 2 a 32 meses. CONCLUSÃO: Conclui-se que é possível realizar transplantes de fígado, com bons resultados, em hospital universitário do Nordeste do Brasil, desde que se reúnam as mínimas condições de estrutura física e recursos humanos.

Abstract
As promoters of orthotopic liver transplantation (OLT) with preservation of caval flow, we reviewed our 8-year experience to assess the feasibility and limits of this technique. Preservation of caval flow during OLT, which improves intraoperative hemodynamic stability, was not considered feasible in a significant proportion of transplant recipients. When transient clamping of caval flow is required, causes and consequences of this clamping during all phases of the procedure were not reported. Between 1991 and 1998, a total of 275 OLTs using a whole graft were performed in 259 patients with a policy consisting of a systematic attempt to preserve inferior vena cava (IVC) and caval flow. Preservation of IVC flow was possible in all cases, and no procedure was converted to the conventional technique. Caval flow was maintained throughout the procedure in 246 procedures (90%). Temporary IVC cross-clamping was required in 24 cases during hepatectomy because of difficult dissection and in 5 cases after graft reperfusion because of outflow obstruction; none required the use of a venovenous shunt. IVC cross-clamping during hepatectomy was required more frequently in cases of a large liver, with a mean duration of 11 +/- 4 minutes, but without significant influence on early postoperative risk, including one graft failure (4%) and one postoperative death (4%). Conversely, IVC cross-clamping after reperfusion, with a mean duration of 23 +/- 5 minutes, was associated with four graft failures (80%) and four deaths (80%). We conclude that IVC preservation is feasible in almost all candidates, allowing the use of split livers from cadaveric or living donors independently from their underlying disease. Although preservation of caval flow was possible in the large majority of cases, transient IVC cross-clamping during hepatectomy was well tolerated in contrast to caval clamping after graft reperfusion. Therefore, if necessary, we recommend transient IVC cross-clamping to perform a large cavocaval anastomosis.

Abstract
BACKGROUND We first introduced the orthotopic liver transplantation utilizing cavaplasty technique in 1994. This paper describes the surgical technique and assesses the outcome of the cavaplasty OLT. METHODS The cavaplasty procedure was used in 115 consecutive orthotopic liver transplantations, including six left lateral and two right lobe transplantations, between November 1994 and September 2000. Fifty-three (66.3%) transplantations required femoro-axillary veno-venous bypass in the initial 4 years, whereas only eight (22.9%) needed VB in the subsequent 2 years. Conversion to piggyback or standard technique was not necessary in any patient. RESULTS Median results are as follows: operative time 4.5 hr, warm ischemia time 25 min, and blood transfused (packed red blood cells) 6 units. These findings did not differ between first transplantation and retransplantation. There were no perioperative deaths related to the cavaplasty technique. No hepatic venous outflow obstruction was observed, including living-related OLTs. No patient required postoperative hemodialysis for acute renal failure. The median intensive care and hospital stays were 2 days and 10 days, respectively. CONCLUSIONS The cavaplasty technique requires no retrocaval, hepatic vein, or short hepatic vein dissection, and the inferior vena cava can be preserved, which provides advantages for hepatectomy and easy hemostasis, especially during retransplantation. The wide-open triangular caval anastomosis is easy to perform, allowing short implantation time and size matching and avoiding outflow obstruction. The short implantation time reduces the need for veno-venous bypass. Our experience indicates that the cavaplasty technique can be applied to all patients and is justified by minimal technical complications.

Abstract
OBJECTIVE To report the authors' experience with adult living donor liver transplantation (ALDLT) without venovenous bypass and to describe modifications that will allow for a direct duct-to-duct biliary reconstruction. SUMMARY BACKGROUND DATA Adult living donor liver transplantation is being evaluated as a method to alleviate the organ shortage. Descriptions of the procedure have emphasized the use of venovenous bypass, portocaval decompression, and the mandatory use of a Roux-en-Y biliary enteric anastomosis. The authors describe a technique for ALDLT without venovenous bypass, portocaval decompression, or caval clamping in 11 recipients and describe the modifications to the procedure that may allow a duct-to-duct biliary reconstruction in certain cases. METHODS Between March 1999 and March 2000, 11 ALDLTs were performed at the authors' institution. All procedures were performed without venovenous bypass, portocaval decompression, or caval clamping. After a modification to the procedure, five of the last six recipients underwent biliary reconstruction with a direct duct-to-duct anastomosis. Data regarding donor, recipient, and graft survival, complications, and graft function were collected. RESULTS Recipients comprised five women and six men, mean age 48 years. Donors comprised five women and six men, mean age 36.5 years. Donor to recipient relationships included sibling, spouse, son, and daughter. Indications for transplantation were hepatitis C, hepatitis C with hepatocellular carcinoma, primary biliary cirrhosis, primary sclerosing cholangitis, ethanol, and cryptogenic. No case required venovenous bypass or portocaval shunting. The right hepatic vein of the donor graft was anastomosed to the confluence of the left and middle hepatic veins in all cases. All donors are alive and well, with no adverse complications reported. Recipient and graft survival rates were 91% and 82%, respectively, for ALDLT versus 92% and 92% for recipients of cadaveric organs during the same time period. One recipient died of multiple organ failure and sepsis. Biliary reconstruction was performed by Roux-en-Y hepaticojejunostomy in the six cases. In five of the last six recipients, direct duct-to-duct biliary reconstruction with a T tube was used. No anastomotic leaks or strictures occurred in the patients undergoing duct-to-duct reconstruction. CONCLUSIONS Adult living donor liver transplantation can be performed safely and may help alleviate the organ shortage. Neither venovenous bypass nor portocaval shunting is necessary to perform the procedure, and modifications to both the donor and recipient hepatectomy procedures may allow biliary reconstruction to be performed by a direct duct-to-duct anastomosis in selected cases.
