ABSTRACT

BACKGROUND: Since the incidence of myocardial infarction and other cardiovascular ischaemic events is highest in early morning, on account of a relative hypercoagulable state occurring in this time period, an attempt was made to test whether reperfusion of the hepatic artery at this time of the day, at liver transplantation, produces an increased risk of early thrombosis. METHODS: The records of 255 consecutive patients receiving a first transplant for chronic liver disease were retrospectively analysed. As possible risk factors, for early post-operative thrombosis (<30 days from transplantation), several medical and surgical parameters were taken into consideration. Arterial reperfusion was considered to have taken place at a time of high coagulability when occurred between 6.00 a.m. and 10.00 a.m. on the basis of previous reports. RESULTS: Logistic regression identified donor age (OR for age >60: P=0.017), bench reconstruction of the artery (OR: 5.06, P=0.013) and time of high coagulability at reperfusion (OR 2.93, P=0.087), as independently associated with early hepatic artery thrombosis. CONCLUSIONS: The present findings identified three independent predictors of early hepatic thrombosis, warranting stricter post-surgical follow-up of patients presenting such conditions. Interestingly, these factors are consistent with arterial reperfusion in the early morning being associated with an increased risk of early hepatic artery thrombosis, suggesting relative coagulative imbalances to provide a contribution in the pathogenesis of this severe complication of liver transplantation.

ABSTRACT

AIM: Kidney transplantation with ureteral duplication may represent a doubled risk factor in terms of ureteral stenosis or necrosis with urinary leakage usually from the site of ureteroneocystostomy. The incidence of complete duplication is very low at 0.19%. We report a kidney with ureteral duplication in the specific setting of multiorgan transplantation since it could be considered an adjunctive risk factor for urological complications. METHODS: The recipient was a 67-year old man, suffering from terminal renal insufficiency. He was also affected by HCV-related cirrhosis. The patient had been waiting for the combined transplantation for 27 months and in the last two months his hepatic function dramatically worsened. The donor was a 53-year old man who died of non-traumatic subarachnoid hemorrhage. Good HLA compatibility was observed between donor and recipient. During harvest both kidneys presented a complete ureteral duplication. So the ureters were freed together with a wide cuff of periureteral tissue and dissected distally. No vascular abnormalities were noted during the removal of either kidney. The grafts were flushed with University of Wisconsin solution and stored in the same solution. RESULTS: The liver was reperfused after 9 hours of cold ischemia. Subsequently the kidney was vascularized after 15 hours of cold ischemia. Urine production occurred immediately after revascularization. Two separated ureteroneocystostomies with a single antireflux technique were performed. Cyclosporine and steroids were given. Post-operative course was uneventful and liver and kidney function were normal. The 7-day cystography was normal. The 6, 12, 24 month ultrasonographies showed no signs of hydronephrosis or hydroureter. After 28 months renal cancer was diagnosed and the patient underwent a right nephrectomy. The liver-kidney recipient had excellent hepatic and renal function for 84.7 months. He died of malignancy from de novo tumor. CONCLUSIONS: On the basis of this experience, a kidney with an ureteral duplication, while rare, can be satisfactorily used also in combined liver-kidney transplantation.

ABSTRACT

INTRODUCTION: Hyperoxygenation of the liver has been suggested to improve its regenerative capacity. Thus, this study sought to determine whether an additional supply of oxygenated blood delivered by portal vein arterialization (PVA) was protective against acute liver failure induced by hepatectomy. METHODS: Sprague-Dawley rats (six per each group) were divided to either undergo PVA or be untreated after extended hepatectomy. Liver injury was evaluated by the serum alanine aminotransferase (ALT) levels. Hepatocyte regeneration was assessed by calculating the mitotic index and bromodeoxyuridine staining. The 10-day survival was assessed in separate experimental groups. RESULTS: The pO(2) in portal blood increased significantly following PVA. Serum ALT levels were significantly reduced in arterialized versus nonarterialized rats. PVA promotes liver regeneration. Finally, PVA significantly improved host survival compared to the controls: 90% versus 30%, respectively. CONCLUSION: These data suggested that an additional supply of arterial oxygenated blood through PVA promoted a rapid regeneration, leading to a faster restoration of liver mass after partial hepatectomy in rats. Thus, PVA may represent a novel tool to optimize hepatocyte regeneration.

ABSTRACT

INTRODUCTION: Optimization of the conditions for regeneration of the native diseased liver is a major goal in patients with acute liver failure. This study sought to determine whether portal vein arterialization (PVA), which increases the oxygen supply to the liver, was protective in a rat model of liver failure. METHODS: At 24 hours after CCl(4) intoxication, Sprague-Dawley rats (six per group) were assigned to receive PVA or as controls. We determined blood tests, histology, and 10-day survivals. Hepatocyte regeneration was assessed by the mitotic index and bromodeoxyuridine (BrdU) incorporation. RESULTS: Serum transaminases were significantly lower in PVA-treated rats than in control animals: liver necrosis resolved rapidly after PVA. The BrdU staining and mitotic index were severalfold higher among PVA-treated than in untreated rats. Survival was 100% among rats with PVA and 40% in untreated animals (P < .01). CONCLUSIONS: PVA led to resolution of CCl(4)-induced massive liver necrosis in the rat. This effect was probably mediated by activation of rapid and extensive hepatocyte regeneration. PVA might provide a novel, alternative approach to treat acute liver failure.

ABSTRACT

Survival rates of patients with acute liver failure (ALF) without transplantation are poor. However, many of them die awaiting a transplant because of the donor organ shortage. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself thus avoiding transplantation is a major goal in their multidisciplinary treatment. Animal experimental studies have shown that portal vein arterialization (PVA) enhances the regenerative capacity of hepatocytes by increasing the oxygen supply to the liver after extended hepatectomy or in toxin-induced ALF models. Furthermore, we have reported the application of PVA in patients with ALF. We herein have described the technical aspects of the PVA procedure both in preclinical models and in man.

ABSTRACT

AIM: We report a series of patients who underwent combined heart-kidney transplantation (CHKT) and combines liver-kidney transplantation (CLKT) at a single center. METHODS: From January 1997 to October 2004, 13 CLKT and 2 CHKT were performed. The CLKT indications were as follows: polycystic disease (2), kidney polycystic disease associated with Caroli (1) and cirrhosis-hepatitis C virus (HCVs) (1), chronic glomerulonephritis with cirrhosis-HCV (4), and other diseases (5). From December 2003 to October 2004, 2 patients underwent CHKT for idiopathic cardiomyopathy plus glomerulonephritis and ischemic cardiomyopathy associated with vascular nephritis. RESULTS: In the CLKT group, 1 patient had acute rejection involving both liver and kidney grafts, whereas 1 patient had liver rejection and another 1 had kidney rejection alone. Of the 13 patients, 10 are alive with a mean survival of 583 days (range, 36-2688 days); 2 patients died within 1 month of transplantation (both with polycystic disease) due to ARDS and MOF. Another patient died 6 years and 9 months after CLKT of metastasis from a de novo tumor. In the CHKT group, no patient suffered heart-kidney rejection. They are all alive at 333 and 116 days, with heart and kidney allografts functioning well. CONCLUSION: In the CLKT group, the worst results were for patients with polycystic disease, in whom a more rigorous selection is necessary because of greater technical difficulties. For the remaining patients we had acceptable complications and excellent long-term results. In selected cases, CHKT can provide long-term graft function and patient survival. Our experience indicates that end-stage kidney failure combined with liver or heart failure does not necessarily preclude dual-organ transplantation.

ABSTRACT

Survival rates of patients with acute liver failure (ALF) without transplantation are poor. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself, avoiding transplantation, is a major goal in the treatment of ALF. We report our clinical experience of portal vein arterialization in one case of massive liver necrosis after liver transplantation and in two patients with ALF caused by idiosyncratic drug reaction and mushroom intoxication. Portal vein arterialization, at least in two cases, was a turning point in the course of the disease since a close temporal association between surgery and clinical improvement was clearly evident. We believe that this novel approach, which should promote liver regeneration by providing an additional oxygen supply to the liver, may disclose a new possibility in the treatment of ALF and prompt new clinical and experimental research.

ABSTRACT

Two hundred seventy-six liver transplants were retrospectively reviewed to analyze 6-month graft survival in relation to the combination of donor quality (standard donor vs nonstandard donor) and risk related to the severity of recipient liver disease low-risk, ie, United Network for Organ Sharing [UNOS] status 3/2b; high-risk, ie, UNOS status 1/2a). The overall 6-month survival rate of 82% was stratified into 4 classes: (1) standard donor to low-risk recipient = 88%; (2) standard donor to high-risk recipient = 86%; (3) nonstandard donor to low-risk recipient = 84%; and (4) nonstandard donor to high-risk recipient = 67%. According to the observed graft survival in the 4 different classes, 2 simulations were performed: the "match simulation" (transplantation of all low-risk recipients using standard donors, and transplantation of all high-risk recipients using nonstandard donors), and the "mismatch simulation" (transplantation of all the high-risk patients using low-risk donors and transplantation of low-risk patients using high-risk donors). The 6-month survival rates, calculated using the match simulation, were 74% and using the mismatch simulation, 84%. The authors suggest that, in the era of marginal donors, the recipient should be selected in relation to the characteristics of the donor according to the mismatch model.

ABSTRACT

INTRODUCTION: A prospective, randomized, multicenter, open clinical trial was performed to compare the main liver function tests, postoperative complications, and early graft and patient survival of recipients transplanted with livers preserved in Celsior (CEL) versus histidine tryptophan ketoglutarate (HTK) solutions. METHODS: We analyzed the data from a single center. Forty livers randomized to CEL (n = 20) or HTK (n = 20) preservation solution were perfused in situ via the aorta and portal vein (CEL, 30 mL/kg via portal vein and 60 mL/kg via aorta; and HTK solution, 30 mL/kg via portal vein and 120 mL/kg via aorta). RESULTS: The groups were comparable with regard to donor, graft, and recipient characteristics. The mean cold ischemia time was 458 minutes (range: 203-667 minutes) in CEL and 450 (range: 310-684 minutes) in HTK. The incidence of initial poor function and primary nonfunction in CEL and HTK were (0 vs 1) and (0 vs 1), respectively. No differences were observed for acute rejection. No vascular or biliary complications were reported in either group. The 3-month graft and patient survival rates were 95% and 95% in CEL and 80% and 90% in HTK. The 12-month graft and patient survival rates were 90% and 90% in CEL and 75% and 85% in HTK. CONCLUSIONS: To our knowledge, this is the first report comparing CEL and HTK preservation solutions in clinical liver preservation. Although a greater 1-year graft and patient survival was observed in the CEL group, a definitive evaluation comparing CEL and HTK solutions in clinical preservation must await completion of the trial.

ABSTRACT

Although octogenarian livers have been transplanted successfully in elective settings, their safety in the case of fulminant hepatic failure has not yet been reported. From November 1998 to June 2003, we transplanted 3 livers from 80-, 82-, and 86-year-old donors. The donors were hemodynamically stable with an intensive care unit stay ranging from 24-48 hours. Cold ischemia time was from 260 minutes to 526 minutes. Mild macrosteatosis was present in 2 donors. Donor and recipient characteristics as well as posttransplantation evolution were evaluated. Two cases had uneventful courses and all recipients are well at 39, 21, and 5 months, respectively. The second recipient underwent retransplantation at 15 days due to technical complications. Livers from octogenarian donors may be safely used in an emergency to save patients. Age does not represent a limit for individually assessed and highly selected donors.

ABSTRACT

INTRODUCTION: To evaluate the influence of pretransplantation recipient and donor prognostic factors on graft-patient survival. MATERIALS AND METHODS: Between April 1986 and June 2003, 40 liver transplantation (LT) procedures to treat fulminant hepatic failure were performed (5.7%). Twenty-one pre-LT recipient and donor variables were retrospectively considered for analysis. RESULTS: The indications for LT were hyperacute (62.5%), acute (35%), and subacute hepatic failure (2.5%). Glasgow Coma Scale scores ranged from <5 in 22 patients to > or =5 in 18 patients. The causes were hepatitis B (n = 21), unknown (n = 10), Amanita phalloides (n = 5), and other (n = 4). The 1-year graft and patient survival rates were 48.3% and 61.3%, respectively. Perioperative and late mortality was 27.5% and 22.5%. The only variable statistically significant for graft survival was waiting list time for LT <48 hours (P = .05). DISCUSSION: Liver transplantation is the best treatment for fulminant hepatic failure, with a 1-year patient survival rate of 61.3%. The short waiting list time has an important role in outcome.

ABSTRACT

INTRODUCTION: Although portal vein thrombosis (PVT) is no longer considered a contraindication for liver transplantation (OLT), it is still considered a high risk because of the complexity of the surgical procedure. The aim of this study was to evaluate the impact of PVT in the recipient during OLT on intra- and perioperative management and outcome. PATIENTS AND METHODS: Between April 1986 and October 2003, 721 primary OLT included 64 patients (8.8%) with PVT. The underlying liver disease was postnecrotic cirrhosis in most cases (n = 37). Intraoperative (length of surgery, packed red blood cells (PRBC) transfusion requirements, ischemia time, complications) and postoperative parameters (ICU stay and hospitalization time, complications, actuarial graft and patient survival at 1 month and 1 and 5 years) were compared with a control group of patients submitted to OLT without PVT (n = 657). RESULTS: Portal flow was reestablished in 56 patients with thromboendovenectomy, in seven patients with a venous graft from the superior mesenteric vein, and with cavoportal hemitransposition in one case. The average ICU and hospital stay as well as the 1-month and 1- and 5-year patient survivals were not significantly different in the PVT versus the control group. We observed slightly more PRBC transfusions and longer surgery procedures in the PVT group. CONCLUSIONS: Our experience suggests that thromboendovenectomy is the procedure of choice for PVT. The results are good in terms of survival rates and postoperative complications, although the presence of PVT may lead to more technical problems during surgery.

ABSTRACT

INTRODUCTION: We aimed to analyze the influence of intraoperative blood transfusion on postoperative complications and survival and to identify the preoperative variables associated with greater intraoperative bleeding. MATERIALS AND METHODS: Thirty-one elective liver transplantations (OLT) without blood transfusion performed between 1986 and 2002 (group 1) were compared with 62 patients (group 2) who underwent elective OLT with intraoperative transfusion after matching for gender, disease severity, and chronology. RESULTS: The hemoglobin and hematocrit values were significantly greater in group 1 compared to group 2. No significant differences were reported for the other parameters. In particular, the type of surgical technique had no influence on the blood requirement. As expected the nontransfused patients received less autologous packed red blood cells compared with the transfused patients. No differences were observed in either group for mean CIT, ICU and hospital stay, or acute rejection. A significant difference was observed in the number of postoperative infectious episodes, which was higher in group 2 (28 vs 5, P = .01). Graft and patient survivals at 3 months and 5 years did not differ significantly between groups. CONCLUSIONS: OLT without blood transfusion may be achieved in the presence of good recipient conditions. Lower preoperative hemoglobin and hematocrit values were associated with greater intraoperative transfusions.

ABSTRACT

INTRODUCTION: The shortage of donors has made it necessary to consider older subjects, those with mild or moderate steatosis, and those who are HBcAb- or hepatitis C virus (HCV)-positive as marginal donors. MATERIALS AND METHODS: From April 1986 to January 2002, 690 orthotopic liver transplantations (OLTs) were performed in 603 patients. In this series we used 68 donors older than 70 years, 51 with steatosis (38 mild, 12 moderate, and 1 severe), 44 were HBcAb-positive and 6 were HCV-positive. RESULTS: Of 68 grafts from donors older than 70 years, 65 were used as a first OLT. These grafts showed 3 PNF, 11 arterial complications, 12 re-OLTs, and 14 deaths with graft survival of 72.3% and 61.34% at 1 and 3 years, respectively. All patients who received the other 3 grafts, which were used for re-OLT, died between postoperative day 21 and 720. Among the 51 grafts with steatosis, we observed 2 PNF of those within the mild steatosis group and graft survival rates of 76.8% and 70.9% at 1 and 3 years, respectively. Forty-four grafts from HBcAb-positive subjects were used in 18 HBsAg-negative and 26 HBsAg-positive recipients. Among the untreated patient group, 1 patient demonstrated hepatitis B virus (HBV) reinfection and 1 patient had de-novo HBV. No reinfection or de novo infections were observed in the 13 patients treated with immunoglobulin or in the 19 patients treated with lamivudine plus immunoglobulin, or in the only patient treated with lamivudine. Graft survival rates were 64.1% and 54.7% at 1 and 3 years, respectively. Among who received 6 patients transplants from HCV-positive donors, we observed 1 recurrence of chronic hepatitis, 1 re-OLT for hepatic vein stenosis, and 1 PNF. CONCLUSION: Old donors, those with moderate steatosis, or those who are HBcAb- and HCV-positive can be safely used in selected recipients to reduce waiting list mortality.

ABSTRACT

BACKGROUND: Celsior (CS) has recently been proposed as a cold storage solution for thoracic and abdominal organs. We compared University of Wisconsin (UW) and CS solutions for the preservation of livers from old donors, with regard to initial function as well as short- and long-term graft and patient survival. METHODS: A multicenter retrospective study from 1998 to 2002 includes 30 livers from octogenarian donors preserved in CS (n = 15) or UW (n = 15) solution prior to transplantation. Donor and recipient clinical and laboratory parameters as well as liver biopsy results were evaluated in all cases. RESULTS: The distribution of the main donor variables as well as recipient characteristics were comparable between groups. Mean cold ischemia time was 421 minutes in the CS group and 474 minutes in the UW group. Mild steatosis was present in 8 cases in the CS group and 7 cases in the UW group. No primary graft dysfunction or arterial or biliary complications were noted. There was 1 acute rejection episode in the CS group and 4 in the UW group. Late postoperative deaths were observed only in the UW group (ie, 7 of 15). Actuarial graft survival was 100% in the CS group vs 86.7% in the UW group (P = NS) at 3 months, and 100% in the CS group vs 52.5% in the UW group (P =.007) at 12 months. Patient survival was 100% in the CS group vs 93.3% in the UW group (P = NS) at 3 months, and 100% in the CS group vs 59.3% in the UW group (P =.01) at 12 months. CONCLUSIONS: Both CS and UW solutions effectively protect livers obtained from donors >80 years of age during the early postoperative course but the CS group had better long-term results.

ABSTRACT

BACKGROUND: The results obtained for combined liver-kidney transplantation (CLKT) are reported. METHODS: From 1997 to 2003 six procedures were performed in patients with polycystic disease (n = 2), chronic glomerulonephritis associated with HCV cirrhosis (n = 2), chronic interstitial nephritis associated with cirrhosis HCV + alcohol (n = 1), and subacute hepatitis caused by drugs (n = 1). The average age of patients was 55 years (5 M and 1 F). The liver transplants were performed using the piggyback technique except in the two polycystic patients, for whom a conventional technique was used. The immunosuppressive therapy was based on cyclosporine in five patients and tacrolimus in one patient. RESULTS: The average blood transfusion was 3670 mL, with larger consumption in the two polycystic cases. Graft function immediately after operation was satisfactory. There were two cases of liver and kidney rejection. In one case, a cardiac arrest occurred during the operation with neurologic consequences. The postoperative complications were cyclosporine neurotoxicity (n = 1), pleuric empyema treated with surgical drainage (n = 1), and CMV infection (n = 1). Four years after CLKT, one patient underwent nephrectomy for a de novo tumor. Of the six patients, four are in good general condition whereas the two polycystic disease patients died within 1 month from transplantation due to ARDS and MOF, respectively. CONCLUSIONS: Based on the worst results of CLKT occurred among patients with polycystic disease, a more rigorous selection is necessary.

ABSTRACT

There are few reports of combined heart and liver transplantation (CHLT) for familial amyloidotic polyneuropathy (FAP). The technique for the operation remains to be defined. Four CHLTs were performed for amyloidogenic transthyretin-related (variant Glu89Gln-ATTR Glu89Gln) cardiomyopathy in our center. Patients 1 and 4 had no serious involvement of other organs, whereas patients 2 and 3 had evident peripheral neuropathy and gastrointestinal motility alterations. Patient 3 also had high-grade orthostatic hypotension. All four patients underwent cardiac and sequential hepatic transplantation with organs procured from the same donor. Venovenous bypass was used in patients 1 and 4 who experienced uncomplicated procedures. The amyloidotic liver of patient 4 was successfully utilized for a domino procedure to treat a patient with hepatocellular carcinoma on cirrhosis. The cardiac performance of patients 1 and 4 remains normal; there has been no progression of amyloidosis at 42 and 1 months after transplantation. Patient 2 had no intraoperative complications but experienced postoperative bleeding, renal failure, sepsis, and heart failure, and finally died of multiorgan failure 2 months after transplant. In patient 3, right hemicolectomy was required intraoperatively due to intestinal ischemia, without significant hemodynamic instability, while extracardiac symptoms of amyloidosis gradually worsened postoperatively. In conclusion, CHLT for ATTR Glu89Gln may be performed even in patients with advanced disease. However, the most compromised patients are more likely to display intraoperative risks, postoperative complications, and worsening of extracardiac, extrahepatic symptoms.

ABSTRACT

The literature provides little data about incisional herniae (IH) developing after orthotopic liver transplantation (OLTx). We evaluated the incidence, predisposing factors, and results of surgical treatment of this pathological condition. We reviewed the records of 718 consecutive OLTx performed in 623 patients between April 1986 and May 2002. Patients whose IH developed after transplantation were included in the study. We identified 31 patients (incidence, 4.9%) whose IH developed from 2 to 140 months after the transplantation. This complication was significantly more frequent in men. Important predisposing factors included: virus-correlated cirrhosis, body mass index >25, severe ascites, incision type for OLTx (bilateral subcostal extended upper midline to xiphoid), and post-OLTx complications. In 17 patients, repair of hernia was performed using direct fascial approximation, in 20 patients, it required a prosthesis. After hernia treatment, we observed no deaths but a morbidity rate of 6.4%, a mean postoperative hospital stay of 8 days and a recurrence rate of 6.4%. IH post-OLTx need surgical treatment.

ABSTRACT

BACKGROUND/AIMS: Bile duct strictures may be malignant or benign. In the absence of previous biliary surgery a precise preoperative diagnosis is often difficult, in particular when a tumor mass is absent in the preoperative radiologic findings. METHODOLOGY: A review of 179 patients observed between 1982 and 2001 by the same surgical team with a preoperative diagnosis of malignant stricture of the biliary tree. A surgical procedure was performed in 153 of these cases. RESULTS: The presence of a malignant stricture was confirmed by final pathologic examination in 32 of 38 cases (96%) in which a curative resection was performed. A final diagnosis of inflammatory stricture secondary to choledocholithiasis was made in 3 of the remaining 6 cases (4%), along with one case each of sclerosing cholangitis, granular cell tumor and Mirizzi's syndrome, respectively. CONCLUSIONS: Precise preoperative evaluation of biliary structures can be very difficult when a tumor mass is absent. Despite the use of invasive procedures and new techniques such as magnetic resonance cholangiopancreatography, a false-positive rate of 4% may be expected. However, whenever a malignancy is not definitely excluded, biliary strictures should be treated as a cholangiocarcinoma.

ABSTRACT

Mirizzi syndrome type II is a form of obstructive jaundice caused by a stone impacted in the gallbladder neck or the cystic duct that impinges on the common hepatic duct with a cholecysto-choledochal fistula. Preoperative recognition is necessary to prevent injury to the common duct during surgery. We present a patient with an operative diagnosis of type II Mirizzi syndrome, which was not originally indicated in the preoperative work-up; in particular endoscopic retrograde cholangiopancreatography showed stenosis of the middle third of the hepatic duct along with markedly elevated serum CA19-9 levels (up to 35,000 U/mL). Surgical specimen examination did not reveal the presence of neoplasia. We performed cholecystectomy and a jejunal loop was brought up and anastomosed to the common duct at the hilar level in a Roux-en-Y fashion. In cases such as ours with extensive fibrosis and inflamed tissue mimicking cholangiocarcinoma or gallbladder carcinoma, a wide hepaticojejunostomy is required to establish adequate biliary drainage.
