RESUMO

BACKGROUND: Laparoscopic liver resection for hepatocellular carcinoma (HCC) in Child-Pugh A cirrhosis has been demonstrated as beneficial. However, the role of laparoscopy in Child-Pugh B cirrhosis is undetermined. The aim of this retrospective cohort study was to compare open and laparoscopic resection for HCC with Child-Pugh B cirrhosis. METHODS: Data on liver resections were gathered from 17 centres. A 1 : 1 propensity score matching was performed according to 17 predefined variables. RESULTS: Of 382 available liver resections, 100 laparoscopic and 100 open resections were matched and analysed. The 90-day postoperative mortality rate was similar in open and laparoscopic groups (4.0 versus 2.0 per cent respectively; P = 0.687). Laparoscopy was associated with lower blood loss (median 110 ml versus 400 ml in the open group; P = 0.004), less morbidity (38.0 versus 51.0 per cent respectively; P = 0.041) and fewer major complications (7.0 versus 21.0 per cent; P = 0.010), and ascites was lower on postoperative days 1, 3 and 5. For laparoscopic resections, patients with portal hypertension developed more complications than those without (26 versus 12 per cent respectively; P = 0.002), and patients with a Child-Pugh B9 score had higher morbidity rates than those with B8 and B7 (7 of 8, 10 of 16 and 21 of 76 respectively; P < 0.001). Median hospital stay was 7.5 (range 2-243) days for laparoscopic liver resection and 18 (3-104) days for the open approach (P = 0.058). The 5-year overall survival rate was 47 per cent for open and 65 per cent for laparoscopic resection (P = 0.142). The 5-year disease-free survival rate was 32 and 37 per cent respectively (P = 0.742). CONCLUSION: Patients without preoperative portal hypertension and Child-Pugh B7 cirrhosis may benefit most from laparoscopic liver surgery.

RESUMO

When the standard arterial reconstruction is not feasible during liver transplantation (LT), aorto-hepatic arterial reconstruction (AHAR) can be the only solution to save the graft. AHAR can be performed on the infrarenal (IR) or supraceliac (SC) tract of the aorta, but the possible effect on outcome of selecting SC versus IR reconstruction is still unclear. One hundred and twenty consecutive patients who underwent liver transplantation with AHAR in six European centres between January 2003 and December 2018 were retrospectively analysed to ascertain whether the incidence of hepatic artery thrombosis (HAT) was influenced by the type of AHAR (IR-AHAR vs. SC-AHAR). In 56/120 (46.6%) cases, an IR anastomosis was performed, always using an interposition arterial conduit. In the other 64/120 (53.4%) cases, an SC anastomosis was performed; an arterial conduit was used in 45/64 (70.3%) cases. Incidence of early (≤ 30 days) HAT was in 6.2% (4/64) in the SC-AHAR and 10.7% (6/56) IR-AHAR group (p = 0.512) whilst incidence of late HAT was significantly lower in the SC-AHAR group (4.7% (3/64) vs 19.6% (11/56) - p = 0.024). IR-AHAR was the only independent risk factor for HAT (exp[B] = 3.915; 95% CI 1.400-10.951; p = 0.009). When AHAR is necessary at liver transplantation, the use of the supraceliac aorta significantly reduces the incidence of hepatic artery thrombosis and should therefore be recommended whenever possible.

RESUMO

BACKGROUND: Laparoscopic liver resection demands expertise and a long learning curve. Resection of the posterosuperior segments is challenging, and there are no data on the learning curve. The aim of this study was to evaluate the learning curve for laparoscopic resection of the posterosuperior segments. METHODS: A cumulative sum (CUSUM) analysis of the difficulty score for resection was undertaken using patient data from four specialized centres. Risk-adjusted CUSUM analysis of duration of operation, blood loss and conversions was performed, adjusting for the difficulty score of the procedures. A receiver operating characteristic (ROC) curve was used to identify the completion of the learning curve. RESULTS: According to the CUSUM analysis of 464 patients, the learning curve showed an initial decrease in the difficulty score followed by an increase and, finally, stabilization. More patients with cirrhosis or previous surgery were operated in the latest phase of the learning curve. A smaller number of wedge resections and a larger number of anatomical resections were performed progressively. Dissection using a Cavitron ultrasonic surgical aspirator and the Pringle manoeuvre were used more frequently with time. Risk-adjusted CUSUM analysis showed a progressive decrease in operating time. Blood loss initially increased slightly, then stabilized and finally decreased over time. A similar trend was found for conversions. The learning curve was estimated to be 40 procedures for wedge and 65 for anatomical resections. CONCLUSION: The learning curve for laparoscopic liver resection of the posterosuperior segments consists of a stepwise process, during which accurate patient selection is key.


ANTECEDENTES: La resección hepática laparoscópica exige experiencia y una larga curva de aprendizaje. La resección de los segmentos posterosuperiores (PS) es un reto, y no hay datos acerca de la curva de aprendizaje (learning curve, LC). El objetivo de este estudio fue evaluar la LC de la resección laparoscópica de los segmentos PS. MÉTODOS: Se realizó un análisis CUSUM de la puntuación de dificultad (difficulty score, DS) de la resección en pacientes de 4 centros especializados. La técnica CUSUM se ajustó al riesgo (risk-adjusted CUSUM, RA-CUSUM) para el tiempo operatorio, la pérdida de sangre y las conversiones a cirugía abierta ajustando según la DS de los procedimientos. Se utilizó una curva ROC para identificar el momento en el que se consideró que la LC había sido completada. RESULTADOS: De acuerdo con el análisis CUSUM de los 464 pacientes incluidos, se observó una DS baja al inicio, que posteriormente se fue incrementando hasta llegar a una estabilización. En la última fase de la LC se operaron más pacientes con cirrosis o cirugía previa. De forma progresiva se fueron reduciendo el número de resecciones hepáticas en cuña y aumentando el de resecciones anatómicas. A lo largo del tiempo se introdujo el CUSA y la maniobra de Pringle con mayor frecuencia. El RA-CUSUM mostró una reducción progresiva del tiempo operatorio. La pérdida de sangre inicialmente aumentó ligeramente, luego se estabilizó y finalmente disminuyó con el tiempo. Una tendencia similar se observó para las conversiones. La LC se estimó en 40 casos para las resecciones en cuña y en 65 casos para las resecciones anatómicas. CONCLUSIÓN: La LC de la resección hepática laparoscópica de los segmentos PS es un proceso paso a paso durante el cual la selección del paciente es clave.

RESUMO

BACKGROUND: Laparoscopic resection of posterosuperior (PS) segments of the liver is hindered by limited visualization and curvilinear resection planes. The aim of this study was to compare outcomes after open and laparoscopic liver resections of PS segments. METHODS: Patients who underwent minor open liver resection (OLR) and laparoscopic liver resection (LLR) between 2006 and 2014 were identified from the institutional databases of seven tertiary referral European hepatobiliary surgical units. Propensity score-matched analysis was used to match groups for known confounders. Perioperative outcomes including complications were assessed using the Dindo-Clavien classification, and the comprehensive complication index was calculated. Survival was analysed with the Kaplan-Meier method. RESULTS: Some 170 patients underwent OLR and 148 had LLR. After propensity score-matched analysis, 86 patients remained in both groups. Overall postoperative complication rates were significantly higher after OLR compared with LLR: 28 versus 14 per cent respectively (P = 0·039). The mean(s.d.) comprehensive complication index was higher in the OLR group, although the difference was not statistically significant (26·7(16·6) versus 18·3(8·0) in the LLR group; P = 0·108). The mean(s.d.) duration of required analgesia and the median (range) duration of postoperative hospital stay were significantly shorter in the LLR group: 3·0(1·1) days versus 1·6(0·8) days in the OLR group (P < 0·001), and 6 (3-44) versus 4 (1-11) days (P < 0·001), respectively. The 3-year recurrence-free survival rates for patients with hepatocellular carcinoma (37 per cent for OLR versus 30 per cent for LLR; P = 0·534) and those with colorectal liver metastases (36 versus 36 per cent respectively; P = 0·440) were not significantly different between the groups. CONCLUSION: LLR of tumours in PS segments is feasible in selected patients. LLR is associated with fewer complications and does not compromise survival compared with OLR.

RESUMO

AIMS: Liver resection is considered the standard treatment of colorectal metastases (CRLM). However, to date, no long term oncological results and data regarding repeat hepatectomy after laparoscopic approach are known. The aim of this study is to analyze single center long-term surgical and oncological outcomes after liver resection for CRLM. METHODS: A total of 57 open resections (OR) were matched with 57 laparoscopic resections (LR) for CRLM. Matching was based mainly on number of metastases, tumor size, segmental position of lesions, type of hepatectomy and type of resection. RESULTS: Morbidity rate was significantly less in the LR group (p = 0.002); the length of hospital stay was 6.5 ± 5 days for the LR group and 9.2 ± 4 days for the OR group (p = 0.005). After a median follow up of 53.7 months for the OR group and 40.9 months for the LR group, the 5-y overall survival rate was 65% and 60% respectively (p = 0.36) and the 5-y disease free survival rate was 38% and 29% respectively (p = 0.24). More patients in the LR group received a third hepatectomy for CRLM relapse than in the OR group (80% vs. 14.3% respectively; p = 0.015). CONCLUSIONS: Laparoscopic resection for CRLM offers advantages in terms of reduced blood loss, morbidity rate and hospital stay. It provides comparable long-term oncological outcomes but can improve further resectability in patients with recurrent disease.

RESUMO

INTRODUCTION: Highly effective antiretroviral therapy in the last decade has increased the survival rates of HIV-positive patients, yielding a greater number of HIV patients suffering from liver-related disease. Liver transplantation (LT) is the only curative treatment for end-stage liver disease (ESLD) associated or not with hepatocellular carcinoma (HCC). PATIENTS AND METHODS: From June 2003 to September 2010, 23 patients underwent cadaveric donor LT for ESLD at our institution. Inclusion criteria followed the Italian Protocol for LT in HIV-positive patients. Immunosuppressive regimens were based on cyclosporine or tacrolimus, eventually switched to Rapamycin. RESULTS: The median CD4 T-cell count was 275/mmc (range=119-924). All patients were affected by ESLD, which was associated with HCC in 14 cases. Ten patients were within the Milan criteria and four patients exceeded them but were within the San Francisco criteria. Conversion from calcineurin inhibitors (CNI) to rapamycin occurred in ten cases. Hepatitis C virus (HCV) recurrence occurred in 13/21 HCV-positive patients. Acute cellular rejection occurred in eight patients with one developing chronic cellular rejection. Overall patient and graft survivals at 80 months were 50% and 45% respectively. DISCUSSION: LT in HIV-positive patients is a feasible procedure, even if in our experience was burdened by a greater incidence of complications including HCV recurrence and infection compared with HIV-negative patients.

RESUMO

Most transplant centers consider severe pulmonary hypertension (PHT) to be an absolute contraindication for orthotopic liver transplantation (OLT). We retrospectively examined the outcome of 24 patients with PHT (group 1) who underwent OLT compared with 24 matched patients (group 2) without PHT, who also underwent OLT. Based on right cardiac catheterization measurements made after the induction of anesthesia for OLT, PHT was defined as mild or moderate-to-severe if the mean pulmonary arterial pressure exceeded 25 or 35 mm Hg, respectively. The incidence of PHT was 9.8% (24/244); 21/24 PHT patients showed mild and 3/24 moderate PHT. Kaplan-Meier survival analysis did not show a significant difference between the two groups. The incidence of pulmonary infections was significantly greater in group 1 (P < .05). The duration of ventilation and intensive care unit stay was similar in the two groups. Echocardiography detected only the three moderate cases of PHT and not the twenty-one cases of mild PHT. Our analysis suggested that mild PHT was common and did not affect patient outcomes after OLT; moderate or severe PHT was uncommon. The two patients with moderate PHT survived OLT and did not succum to PHT during long-term follow-up.

RESUMO

Disorders in lipoprotein metabolism do not contraindicate liver procurement and transplantation (LT). In this circumstance, LT provides an intriguing opportunity to assess the in vivo contribution of the liver to the synthesis and degradation of genetically polymorphic plasma proteins. Apolipoprotein (APO) E exists with several common phenotypic differences due to gene polymorphism. Some authors have shown that the APOE phenotype of the recipient was virtually completely converted to that of the donor, providing evidence that >90% of plasma APOE arises from the liver. Homozygosis for APOE2 (E2-E2) is related to an increased incidence of type III hyperlipoproteinemia (HLP). Recently, some authors have identified 4 new APOE mutations that are strongly linked to a unique entity of renal lipidosis called lipoprotein glomerulopathy (LPG). At present, 65 cases of LPG have been reported worldwide, although most patients have been discovered in Japan and other East Asian countries. We have herein reported a case of LT in a patient with advanced hepatocarcinoma who received a liver from a caucasian donor affected by type III HLP due to homozygous E2-E2. The LPG was due to a novel genetic mutation in APOE. After the LT, the recipient, developed de novo severe lipid abnormalities despite good graft function. To our knowledge this is the first report of an LT using a graft from a non Asian donor with homozygous E2-E2 with the presence of a novel APOE mutation.

RESUMO

The transjugular intrahepatic portosystemic shunt (TIPS) is an acceptable procedure that has proven benefits in the treatment of patients who have complications from portal hypertension due to liver cirrhosis. In the literature few reports have described complications after TIPS placement. Initial surgery and local hemostasis have been needed to manage abdominal bleeding: if this treatment is insufficient, it may be necessary to perform a liver transplantation. This report describes the role of liver transplantation to manage dangerous complications in 2 patients after TIPS placement, when surgical procedures and hemostasis were unable to stop the bleeding.

RESUMO

AIM: Radical resection is the only potential cure for pancreatic malignancies and a useful treatment for other benign diseases, such as pancreatitis. Over the last two decades, medical and surgical improvements have drastically changed the postoperative outcome of elderly patients undergoing pancreatic resection, and appropriate treatment for elderly potential candidates for pancreatic resection has become an important issue. METHODS: A hundred and five consecutive patients undergoing radical pancreatic resection between 2003 and 2007 at the Surgery Unit of the University of Modena, Italy, were considered and divided into two groups according to their age, i.e., over 75-year olds (group 1, 25 patients) and under 75-year-olds (group 2, 80 patients). The two groups were compared as regards to demographic features, American Society of Anesthesiologists scores, comorbidities, previous major surgery, surgical procedure, postoperative mortality, and morbidity. RESULTS: There were no significant differences between the two groups concerning postoperative mortality, and the duration of hospital stay and days in the postoperative Intensive Care Unit were also similar. Complications such as pancreatic fistulas, wound infections, and pneumonia were more frequent in the older group, but the differences were not statistically significant. CONCLUSION: In the light of these findings and as reported for other series, old age is probably not directly related with any increase in the rate of postoperative complications, but comorbidities (which are naturally related to the patients' previous life) may have a key role in the postoperative course.

RESUMO

Expansion of the donor pool has led to reconsideration of selection criteria to obtain the largest number of grafts without compromising recipient outcomes. This reconsideration concerns the utilization of donors with malignancies. Herein we have analyzed the outcomes, survivals, and risks of cancer transmission among patients who received a liver transplant from a donor with a genitourinary malignancy. Six of 363 patients (1.5%) who underwent transplantation at our center received an organ from a donor with a genitourinary cancer which was detected prior to the surgical harvest. Donors affected by low-grade renal cell carcinoma (Fuhrman grade 1 or 2) or low-grade intraprostatic prostate carcinoma (Gleason score

RESUMO

BACKGROUND: The use of the Model for End-stage Liver Disease (MELD) score to prioritize patients on liver waiting lists and to share organs among centers was effective according to US data, but few reports are available in Europe. MATERIALS AND METHODS: We evaluated the outcome of 887 patients listed between April 2004 and July 2006 in a common list by two transplant centers (University of Bologna [BO] and University of Modena [MO] ordered according to the MELD system. Patients with hepatocellular carcinoma had a score calculated according to their real MELD, tumor stage, and waiting time. RESULTS: Five hundred eighty-six (67%) patients were listed from BO and 291 (33%) from MO. The clinical features of recipients (sex, age, blood group, and real MELD) were comparable between centers. The number of liver transplantations performed was 307, and 273 (89%) recipients had a calculated MELD >or=20. Liver transplantations were equally distributed according to the number of patients listed: 215 out of 586 (36.7%) for BO and 92 out of 291 (31.6%) for MO. The median real MELD of patients transplanted was 20, and 246 out of 307 (80.1%) grafts transplanted were functioning. The dropouts from the list were 124 (14%), and 87 (70%) of these patients had a calculated MELD >or=20. CONCLUSION: The MELD system was effective to share livers among the two Italian centers. According to this policy, livers were allocated to the recipients with the highest probability of dropout and who had a satisfactory survival after liver transplantation.

RESUMO

INTRODUCTION: Anemia after orthotopic liver transplantation (OLT) is a common complication due to several reasons. Immunosuppressive drugs play an important role in anemia occurring at 1 month or more after OLT. Several studies describe myelosuppression immunosuppressants such as the mammalian target of rapamycin inhibitors. METHODS: We performed a single-center, prospective trial consisting of a short 30-day course of cyclosporine (CsA) associated with everolimus (EVL) from postoperative day 10 (Group EVL) versus a CsA immunosuppressive regimen (Group CsA) in de novo OLT patients. We explored the influence of immunosuppressive drugs on hematological parameters comparing EVL versus CsA. RESULTS: Twenty-eight patients were enrolled in the EVL and 12 in the CsA Groups. After OLT, hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), white blood cell (WBC), platelets (PLT), transferrin saturation (TSAT), iron, ferritin, and transferrin did not differ significantly between the 2 groups at any time point. Among the patients who reached 6-months of follow-up, 5 (41.7%) EVL and 4 (80%) CsA subjects were anemic (P=not significant [NS]). Only anemia in patients enrolled in Group EVL showed a trend toward the features of microcytic, hypochromic anemia. DISCUSSION: Our results demonstrated that de novo anemia in OLT patients treated with EVL monotherapy showed the same incidence as in patients treated with CsA. Hb values remained similar during the entire follow-up. Moreover, overall myelosuppression in the EVL Group was not significantly different from patients in the CsA Group.

RESUMO

INTRODUCTION: Highly active antiretroviral therapy (HAART) has been able to improve the immune system function and survival of HIV patients with a consequent increase in the number of HIV patients affected by end-stage liver disease (ESLD). Between June 2003 and October 2006, 10 HIV-positive patients underwent liver transplantations in our center. METHODS: All patients were treated with HAART before transplantation; treatment was interrupted on transplantation day and was restarted once the patients' conditions stabilized. Five patients were hepatitis C virus (HCV)-positive, 3 were hepatitis B virus (HBV)-positive, and 2 were HBV-HCV coinfected. HIV viral load before transplantation was <50 copies/mL in all cases. CD4+ cell count before transplantation ranged between 144 and 530 c/microL. Immunosuppression was based on Cyclosporine (CyA) and steroid weaning for 8 patients, and on Tacrolimus and steroid weaning for 2 patients. RESULTS: Five patients were cytomegalovirus (CMV)-positive pp65 antigenemia posttransplantation, and 1 patient was EBV-positive; 2 patients had a coinfection with HHV6. Four patients suffered from a cholestatic HCV recurrent hepatitis treated with antiviral therapy (peginterferon and Ribavirin). Three patients died after transplantation. DISCUSSION: The outcome of liver transplantation in HIV patients was influenced by infections (HCV, CMV, and EBV) and Kaposi's Sarcoma. HCV recurrence was more aggressive, showing a faster progression in this patient population. Drug interaction between HAART and immunosuppressants occurs; longer follow-up and better experience may improve the management of these drug interactions.

RESUMO

Hemophilia B is a congenital recessive disorder caused by deficiency of coagulation factor IX (FIX). Surgical procedures can be performed in patients with hemophilia using high-purity and/or recombinant FIX, which has been shown to be safe and effective in surgical hemostasis. Liver transplantation is the only potentially curative treatment available for these patients, providing a long-term phenotypic cure for hemophilia. End-stage liver disease together with hemophilia exposes patients to greater risks of bleeding complications during the perioperative period with consequent difficulties in managing coagulopathy. The limited experiences reported by different investigators and the various strategies for clotting factor replacement make it difficult to define a single approach with respect to the optimal dose and method of administering FIX to achieve perioperative hemostasis. The limits of plasma-based coagulation tests--prothrombin time, activated partial thromboplastin time--have made thromboelastography a valid alternative in this kind of surgery. It has been demonstrated to be a useful tool for real-time analysis of clot formation using a whole-blood assay format. Further, it accurately illustrates the clinical effects of procoagulant or anticoagulant interventions. In this article, we have described the usefulness of thromboelastography to monitor the ability of high-purity FIX supplementation to restore a normal coagulation state and to guide the perioperative administration of blood products in a successful orthotopic liver transplantation in a hemophilic patient with deficiencies of factors IX and X, presenting with hepatitis C virus-related cirrhosis and hepatocellular carcinoma.

RESUMO

INTRODUCTION: Several reports have shown the effectiveness of liver transplantation (LT) as a therapeutic option in HIV-patients affected by end-stage liver disease. HCC on cirrhosis is another major indication for LT. However, no reports, to our knowledge, have been published as yet addressing the important questions of indications and outcome of LT in HIV-patients with HCC, mainly because of concerns regarding a more aggressive course of HCC with respect to HCC seen in HIV-negative individuals. METHODS: The aim of this report is to focus on indications, preliminary results and complications of LT in a group of 7 HIV-patients who underwent LT at our department for HCC on cirrhosis. RESULTS: Indications to listing HIV-patients were HCC using the internationally accepted Milan criteria. All patients were HBV-and/or HCV-infected. The mean CD4+ cell-count was 249 (range 144-353), and the HIV-RNA load was undetectable in all but one case. After a mean follow-up period of 232days (range 33-774), no recurrence of HCC was seen; one patient died. CONCLUSION: Characteristics of the study protocol, the patients, virological and immunological features, tumor stage and pre-transplantation treatment, complications and survival are herein described in an effort to provide new insights into methodology for an aggressive management of HCC in HIV patients, and possibly give a greater chance of cure.

RESUMO

INTRODUCTION: Since 1999, a new immunosuppressive drug was administered to renal transplant patients. The SRL molecule acts by blocking post-receptor signal transduction of interleukin-2 (IL-2) interacting with a family of intracellular binding proteins termed immunophilins FKBPs. Among these FKBPs, FK506 12-kd binding protein is the most relevant. SRL is an immunosuppressive drug. Therefore it can inhibit the immune system; at the same time the drug is not nephrotoxic, neurotoxic, and without diabetogenic effects. METHODS: Among 285 patients who underwent liver transplantation, 27 took Sirolimus as monotherapy. Immunosuppressive treatment upto cyclosporine (CsA) or tacrolimus (FK) associated with steroids (methylprednisolone) and mycophenolate Mofetil (MMF) was initiated among subjects with pre-transplant renal failure. SRL was administered as monotherapy for patients who developed nephrotoxicity, or neurotoxicity, or diabetes. Moreover, patients affected by multifocal HCC who did not meet the Milan criteria or patients who developed Kaposi's Sarcoma were prescribed SRL monotherapy. RESULTS: Nephrotoxicity occurred in 14 patients with mean serum creatinine level 2.2 mg/dl. Eleven patients with real failure showed significant improvements after a mean period of 28 days of SRL monotherapy (range: 6-45 days). The mean creatinine serum level after treatment with SRL monotherapy was 1.0 mg/dl (range: 0.7-1.2 mg/dl). Neurotoxicity occurred in 4 patients with tremor, confusion, and agitation. Each patient had complete improvement of symptoms after a few days of Sirolimus monotherapy. Among Three patients who developed Kaposi's Sarcoma, two underwent remission. One patient had diabetes due to calcineurin inhibitors, and one showed arterial hypertension not treatable with drugs. After the switch, we treated these patients with medications. Another important indication was HCC not meeting the Milan criteria. CONCLUSION: SRL monotherapy may be used to manage complication of calcineurin inhibitors or Kaposi's Sarcoma.

RESUMO

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.
