The impact of ileal pouch-anal anastomosis on graft survival following liver transplantation for primary sclerosing cholangitis.

BACKGROUND: Liver transplantation is the only life-extending intervention for primary sclerosing cholangitis (PSC). Given the co-existence with colitis, patients may also require colectomy; a factor potentially conferring improved post-transplant outcomes. AIM: To determine the impact of restorative surgery via ileal pouch-anal anastomosis (IPAA) vs retaining an end ileostomy on liver-related outcomes post-transplantation. METHODS: Graft survival was evaluated across a prospectively accrued transplant database, stratified according to colectomy status and type. RESULTS: Between 1990 and 2016, 240 individuals with PSC/colitis underwent transplantation (cumulative 1870 patient-years until first graft loss or last follow-up date), of whom 75 also required colectomy. A heightened incidence of graft loss was observed for the IPAA group vs those retaining an end ileostomy (2.8 vs 0.4 per 100 patient-years, log-rank P = 0.005), whereas rates between IPAA vs no colectomy groups were not significantly different (2.8 vs 1.7, P = 0.1). In addition, the ileostomy group experienced significantly lower graft loss rates vs. patients retaining an intact colon (P = 0.044). The risks conferred by IPAA persisted when taking into account timing of colectomy as related to liver transplantation via time-dependent Cox regression analysis. Hepatic artery thrombosis and biliary strictures were the principal aetiologies of graft loss overall. Incidence rates for both were not significantly different between IPAA and no colectomy groups (P = 0.092 and P = 0.358); however, end ileostomy appeared protective (P = 0.007 and 0.031, respectively). CONCLUSION: In PSC, liver transplantation, colectomy + IPAA is associated with similar incidence rates of hepatic artery thrombosis, recurrent biliary strictures and re-transplantation compared with no colectomy. Colectomy + end ileostomy confers more favourable graft outcomes.

Pediatric Liver Transplant Recipients Who Undergo Transfer to the Adult Healthcare Service Have Good Long-Term Outcomes.

Liver transplantation has transformed survival for children with liver disease necessitating the transfer of a growing number of patients to the adult healthcare service. The impact of transfer on outcomes remains unclear. The aim of this single-center study of 137 consecutive pediatric liver transplant recipients was to examine the effect of transfer on patient and graft survival. The median time from transplant to transfer was 10.4 years and the median age of the patients at transfer was 18.6 years. After transfer, there were 5 re-transplants and 12 deaths in 14 patients. The estimated posttransfer 10-year patient and graft survival was 89.9% and 86.2%, respectively. Overall, 4 patients demonstrated graft loss as a consequence of chronic rejection. Graft loss was associated with older age at first transplant (p = 0.008). When compared to young adult patients transplanted in the adult center, the transferred patients did not have inferior graft survival from the point of transfer (HR 0.28; 95% CI 0.10-0.77, p = 0.014). This suggests that transfer did not impact significantly on graft longevity. In conclusion, pediatric liver transplant recipients who undergo transfer to the adult service have good long-term outcomes.

Donation after cardiac death liver transplant recipients have an increased frequency of acute kidney injury.

Donation after cardiac death (DCD) liver transplantation is associated with an increased frequency of hepato-biliary complications. The implications for renal function have not been explored previously. The aims of this single-center study of 88 consecutive DCD liver transplant recipients were (1) to compare renal outcomes with propensity-risk-matched donation after brain death (DBD) patients and (2) in the DCD patients specifically to examine the risk factors for acute kidney injury (AKI; peak creatinine ≥2 times baseline) and chronic kidney disease (CKD; eGFR <60 mL/min/1.73 m(2) ). During the immediate postoperative period DCD liver transplantation was associated with an increased incidence of AKI (DCD, 53.4%; DBD 31.8%, p = 0.004). In DCD patients AKI was a risk factor for CKD (p = 0.035) and mortality (p = 0.017). The cumulative incidence of CKD by 3 years post-transplant was 53.7% and 42.1% for DCD and DBD patients, respectively (p = 0.774). Importantly, increasing peak perioperative aspartate aminotransferase, a surrogate marker of hepatic ischemia reperfusion injury, was the only consistent predictor of renal dysfunction after DCD transplantation (AKI, p < 0.001; CKD, p = 0.032). In conclusion, DCD liver transplantation is associated with an increased frequency of AKI. The findings suggest that hepatic ischemia reperfusion injury may play a critical role in the pathogenesis of post-transplant renal dysfunction.

Long-term impact of liver transplantation on respiratory function and nutritional status in children and adults with cystic fibrosis.

Early liver transplant (LT) has been advocated for patients with cystic fibrosis liver disease (CFLD) and evidence of deterioration in nutritional state and respiratory function to prevent further decline. However, the impact of single LT on long-term respiratory function and nutritional status has not been adequately addressed. We performed a retrospective analysis of the outcomes of 40 (21 adult/19 pediatric) patients with CFLD transplanted between 1987 and 2009 with median follow-up of 47.8 months (range 4-180). One and five-year actuarial survival rates were 85%/64% for adult and 90%/85% for pediatric LT cohorts, respectively. Lung function remained stable until 4 years (FEV(1) % predicted; pretransplant 48.4% vs. 45.9%, 4 years posttransplant) but declined by 5 years (42.4%). Up to 4 years posttransplant mean annual decline in FEV(1) % was lower (0.74%; p = 0.04) compared with the predicted 3% annual decline in CF patients with comorbidity including diabetes. Number of courses of intravenous antibiotics was reduced following LT, from 3.9/year pretransplant to 1.1/year, 5 years posttransplant. Body mass index was preserved posttransplant; 18.0 kg/m(2) (range 15-24.3) pretransplant versus 19.6 kg/m(2) (range 16.4-22.7) 5 years posttransplant. In conclusion, LT is an effective treatment for selected patients with cirrhosis due to CFLD, stabilizing aspects of long-term lung function and preserving nutritional status.

Haematological malignancies presenting with acute liver injury: a single-centre experience.

INTRODUCTION: Early recognition and identification of the underlying cause of acute liver injury (ALI) is crucial in instituting medical treatment and assessing the need for liver transplantation. Haematological malignancies have been reported to present as ALI with progression to acute liver failure but experience is limited. AIM: Review our experience of ALI secondary to haematological malignancies. PATIENTS AND METHODS: Patients admitted to the liver unit with ALI secondary to a haematological malignancy between 1996 and 2006 were identified. A retrospective review was made of their case notes and our database. RESULTS: Of the 752 cases of ALI, six cases of ALI secondary to haematological malignancy were identified. Common features were a prodromal illness (median duration of 5 weeks; range 2-6 weeks) and jaundice (median bilirubin 208 micromol/l; range 112-238 micromol/l). The majority of patients (5/6) had hepatomegaly. Liver biopsy was performed in two patients and confirmed the diagnosis in both cases. In other cases, the diagnosis was made following lymph node biopsy (1), bone marrow examination (2) or from post-mortem examination (1). Median time from jaundice to encephalopathy was 12 days; range 1-22 days. A single patient underwent liver transplantation but died in the immediate post-operative period. All patients died soon after admission with a median survival of 8 days (range 3-26 days). CONCLUSION: Haematological malignancy should be considered in ALI patients presenting with a prodromal illness, jaundice and hepatomegaly. Biopsy is essential to confirm the diagnosis but the benefit of definitive therapy such as chemotherapy and/or transplantation in this setting is unclear and survival is poor.

Donor HLA-C genotype has a profound impact on the clinical outcome following liver transplantation.

Late allograft dysfunction is a significant problem following liver transplantation and its pathogenesis is uncertain. HLA-C is the major inhibitory ligand for killer immunoglobulin-like receptors (KIRs) that regulate the cytotoxic activity of natural killer (NK) cells. HLA-C alleles can be allocated into two groups, termed HLA-C1 and HLA-C2, based on their KIR specificity. HLA-C2 interactions are more inhibiting to NK cell activation. We studied the clinical importance of HLA-C genotype in a large liver transplant cohort and found that possession of at least one HLA-C2 allele by the donor allograft was associated with less histological evidence of chronic rejection and graft cirrhosis, a 16.2% reduction in graft loss (p = 0.003) (hazard ratio: 2.7, 95% CI 1.4-5.3) and a 13.6% improvement in patient survival (p = 0.01) (hazard ratio: 1.9, 95% CI 1.1-3.3) at 10 years. Transplantation of an HLA-C2 homozygous allograft led to a particularly striking 26.5% reduction in graft loss (p < 0.001) (hazard ratio: 7.2, 95% CI 2.2-23.0) at 10 years when compared to HLA-C1 homozygous allografts. Donor HLA-C genotype is therefore a major determinant of clinical outcome after liver transplantation and reveals the importance of NK cells in chronic rejection and graft cirrhosis. Modulation of HLA-C and KIR interactions represents an important novel approach to promote long-term graft and patient survival.

Cholangiocarcinoma complicating primary sclerosing cholangitis: a 24-year experience.

AIM: To report the prevalence and outcome of cholangiocarcinoma arising in primary sclerosing cholangitis for a British tertiary referral centre. METHODS: All patients diagnosed with primary sclerosing cholangitis and concurrent cholangiocarcinoma were identified from a prospectively maintained departmental database, and the mode of presentation, management and outcome were determined. RESULTS: Of 370 patients with primary sclerosing cholangitis, 48 patients (13%) were diagnosed with a cholangiocarcinoma within a median time of 0.51 months (range: 0-73.12) from presentation to the unit. Mode of presentation included: inoperable tumours (n = 14); incidental findings in transplant hepatectomy specimens (n = 13); primary sclerosing cholangitis follow-up (n = 9); transplant work-up (n = 5); transplant waiting list (n = 5); suspected tumour confirmed at transplant (n = 1), and incidental finding at cholecystectomy (n = 1). The diagnosis was confirmed by: radiology-guided biopsy (n = 27); MRI (n = 3); CT (n = 2); laparoscopy or laparotomy (n = 2), and frozen section at transplant (n = 1). Management consisted of: transplantation (n = 14, including 1 abandoned); hepatic resection (n = 8), and palliation through stenting (n = 26). The overall median survival of the cohort was 4.9 months (range: 0.09-104.5). Median survival ranged from 2.6 months (range: 0.09-35.3) for palliation to 7.6 months (range: 0.6-99.6) for transplantation and 52.8 months (range: 3.7-104.5) for resection. There was no difference in survival between the transplant and resection groups (p = 0.14). CONCLUSIONS: Cholangiocarcinoma is a common finding in primary sclerosing cholangitis and regular screening of this cohort of patients at referring centres is advocated to detect early tumours, as surgical treatment at an early stage offers significantly better outcomes for this cohort of patients.

Post-transplant lymphoproliferative disease in liver transplantation.

Post-transplant lymphoproliferative disease (PTLD) is a well recognized complication of solid organ transplantation and therapeutic immunosuppression, first reported in 1968. PTLD incorporates a spectrum of abnormalities ranging from a benign infectious mononucleosis-like illness to non-Hodgkin's lymphoma with nodal and extranodal site involvement. The first liver transplant was performed at our institution in January 1982. This retrospective study examined the incidence of PTLD, reason for the original transplants, presenting symptoms, radiological findings, immunosuppression regimens and outcomes of these patients. From a total of 2005 adult liver transplants, 23 patients (1.1%) were identified with PTLD. The average age of these patients at the time of transplant was 46.5 years, with a ratio of female-to-male of 14:9. Indication for transplant ranged from primary biliary cirrhosis (eight patients) to epitheloid haemangioendothelioma (one patient). The average time interval between transplant and diagnosis of PTLD was 50 months. Imaging abnormalities identified included generalized lymphadenopathy, liver and portal masses, splenic enlargement, bowel, eye, cerebral and neck involvement; and in two patients, no radiological abnormality. The most common histological findings ranged from B-cell non-Hodgkin's lymphoma (five patients) to early PTLD in one patient. Our rate of PTLD is lower compared with published literature and demonstrates a much longer time interval from transplant to occurrence of PTLD than previously appreciated. This could be secondary to a low immunosuppression therapy followed at our institution. From a few months to several years after liver transplantation, the radiologist needs to be alert to the possibility of PTLD and thorough imaging is required to detect the wide variety of potential presentations.

Primary hepatocellular cancer in the explanted liver: outcome of transplantation and risk factors for HCC recurrence.

AIM: To evaluate the risk of recurrence of hepatocellular cancer (HCC) after liver transplantation (LT). METHODS: The clinical records of 104 patients with HCC in the explanted liver were examined. RESULTS: HCC recurrence occurred in 12 patients. Recurrence was observed in all patients with a single nodule greater than 5 cm. Among the 5 patients with more than 3 tumours with a maximum diameter of 4.5 cm, no recurrence occurred. The survival rates were 81% and 64% at 1 and 5 years, respectively; the recurrence-free survival at 1 and 5 years was, respectively, 93% and 82%. Pre-LT alpha-fetoprotein (AFP) increased at a greater magnitude in patients who experienced recurrence, compared to those who did not. Tumour diameter, differentiation, satellitosis, AFP and the magnitude of AFP increase were predictive of recurrence. The 1- and 5-year recurrence-free survival for the 68 patients who had a single nodule up to 5 cm, or up to 3 nodules all less than 4.5 cm and with a maximum cumulative diameter of 8 cm, or more than 3 nodules all less than 2.5 cm, were 95% and 92%, respectively. For the 13 patients not meeting these criteria, the 1- and 5-year recurrence-free survival was, respectively, 75% and 54% (log Rank test p=0.019). CONCLUSIONS: Patients with more than 3 small HCC nodules before LT could still have a good outcome without recurrence. A rapid increase in AFP could be useful in identifying patients with a greater risk of post-LT HCC recurrence.

Favourable medium term outcome following hepatic vein recanalisation and/or transjugular intrahepatic portosystemic shunt for Budd Chiari syndrome.

BACKGROUND: We report our experience with management of patients with Budd Chiari syndrome over the past two decades. In 1996 we described a novel approach involving recanalisation of hepatic veins by combined percutaneous and transvenous approaches. This was incorporated into an algorithm published in 1999 in which our preferred treatment for all cases of Budd Chiari syndrome with short segment occlusion or stenosis of the hepatic veins involves recanalisation of the hepatic veins by transvenous or combined percutaneous-transvenous approaches. In symptomatic Budd Chiari syndrome where recanalisation is not possible, we perform transjugular intrahepatic portosystemic shunts (TIPS) because TIPS decompresses the portal circulation directly in an adjustable way. In this series of patients with Budd Chiari syndrome treated with radiological interventions alone, we assess their medium term outcome using two independent objective prognostic indices. METHODS: We retrospectively studied 61 patients with non-malignant Budd Chiari syndrome treated by radiological intervention alone in our centre. RESULTS: Actuarial survival for the entire cohort at one year and five years was 94% and 87%, respectively. Survival of our patients with mild disease (according to the Murad classification) was 100% at one year and at five years, with intermediate disease severity 94% at one year and 86% at five years, and with severe disease 85% at one year and 77% at five years. CONCLUSION: Management of Budd Chiari syndrome by interventional radiology resulted in excellent medium term survival for patients in all categories of disease severity.

Analysis of marginal donor parameters in liver transplantation for primary biliary cirrhosis.

The shortage in cadaveric donor livers is pushing the transplant centers to expand the pool by using "marginal" donors. Primary biliary cirrhosis (PBC) remains an important indication for transplantation. We conducted a retrospective analysis of prospectively collected data in a well-defined group of patients with PBC where 301 consecutive donor-PBC recipient pairs transplanted were analyzed to identify donor and operative factors influencing recipient outcome. Mean follow-up was 56 months. The 1-, 3- and 5-year actuarial patient and graft survival was 93.97%, 90.64%, and 81.75%, and 85.49%, 82.57%, and 75.21%, respectively. Factors showing influence in decreased total patient survival were recipient old age (P = 0.003) and low recipient albumin (P = 0.01). However, the only variables showing an association with decreased patient survival within 90 days are old donor age (P = 0.002) and high donor body weight (P = 0.03) or high body mass index (BMI) (P = 0.055). Cold ischaemic time (CIT) of 18 hours showed statistical significance in patient survival (P = 0.025). Obesity did have a significant adverse impact on survival compared with normal or overweight donors (BMI < 30), decreasing survival by 50% at 5 years. In conclusion, this study of several factors considered "marginal" for transplantation in a recipient population with predictable liver disease (PBC), donor BMI and age were shown to be associated with decreased graft and patient survival.

Liver resection for colorectal metastases.

BACKGROUND: Colorectal cancer is the second commonest malignancy in the UK. Metastases to the liver occur in greater than 50% of patients and remain the biggest determinant of outcome in these patients. Liver resection is a safe procedure that achieves good long-term survival, but surgery has traditionally been limited to select groups of patients. The improved outcome suggests that more patients could benefit from resection if more was known of what criteria are predictive of a good outcome. PATIENTS AND METHODS: A retrospective analysis was performed on all patients undergoing surgical resection of the liver for colorectal metastases between March 1989 and March 2001 in the Birmingham Liver Unit. RESULTS: During this period, 212 liver resections for colorectal cancer metastases were performed in 82 females and 130 males. The median follow-up was 16 months with an overall actuarial survival of 86% at 1 year, 54% at 3 years, and 28% at 5 years. The peri-operative mortality was 2.8%. The number and timing (metachronous or synchronous) of metastatic lesions, the gender of the patient, pathological staging of the primary lesion or surgical resection margins had no significant influence on survival. Patients with lesions less than 5 cm in size had a significantly prolonged survival compared with patients with lesions greater than 5 cm in size (P < 0.004). CONCLUSIONS: Liver resection is the only curative treatment for patients with colorectal metastases. The long-term survival reported in patients with resected colorectal metastases confined to the liver is comparable to primary surgery for solid gastrointestinal tumours. Every attempt must be made to increase the availability of liver resection to patients with hepatic metastases from colorectal cancer.

Delayed hepatic artery thrombosis in adult orthotopic liver transplantation-a 12-year experience.

BACKGROUND: Although the clinical features of early hepatic artery thrombosis (HAT) are well defined, the features of delayed (more than 4 weeks after transplantation) hepatic artery thrombosis are less clearly defined. The aim of our study was to identify risk factors, clinical presentation, and outcome of management of delayed hepatic artery thrombosis (HAT) after liver transplant (LTx). METHODS: An analysis of prospectively collected data of all patients transplanted from 1986 to 1998 was performed. The importance of recipient (age, sex, primary indication for LTx, cytomegalovirus status, and intraabdominal sepsis) and donor factors (donor age, cold ischemia time, and donor cytomegalovirus status), modes of presentation, and outcome of treatment (biliary reconstruction/stenting, regraft, vascular reconstruction, observation) were analyzed. RESULTS: Delayed HAT was seen in 31/1097 adult LTx recipients (incidence 2.8%). No recipient or donor factors were identified as risk factors. A total of 16 patients were symptomatic at presentation (HAT diagnosed on abdominal ultrasound). Six patients had recurrent episodes of cholangitis, four had cholangitis with a stricture, four had cholangitis and intrahepatic abscesses, and two had bile leaks. Biliary reconstruction was done in six patients (all of whom subsequently required a regraft), vascular reconstruction was performed in two patients (one regrafted and one died shortly after), four patients with cholangitis and stricture on presentation had a biliary stent (all four were later regrafted). A total of 16 patients were regrafted, 9 are alive, 5 died within 6 months (septic at time of LTx), 1 died after 1 year, and 1 died after 2 years. Fifteen patients were asymptomatic and detected on routine screening. 5 have remained asymptomatic and are still alive, 1 developed a biliary stricture that was stented and is alive 105 months later, 4 had recurrence of the original disease, 3 developed progressive graft failure and were listed for transplant but died before regraft due to overwhelming sepsis and hepatic encephalopathy. Two patients died due to nonbiliary sepsis. CONCLUSIONS: Delayed HAT is a rare complication of LTx that may present with biliary sepsis, or remain asymptomatic. Biliary or vascular reconstructions do not increase graft survival. Of the patients who were clinically silent on presentation, 20% developed progressive graft failure requiring a second transplant. A total of 33% survived in the long-term without a second transplant. Ongoing severe sepsis at the time of regraft results in poor survival.

Type of donor aortic preservation solution and not cold ischemia time is a major determinant of biliary strictures after liver transplantation.

The development of biliary strictures (BSs) after liver transplantation (LT) continues to affect 10% to 30% of patients, causing substantial morbidity. The cause of BSs is multifactorial, including technical, immune, and, in particular, ischemic factors. The importance of adequate flushing of the peribiliary arterial tree has been stressed. We hypothesized that high-viscosity (HV) preservation solutions in the donor do not completely flush the small donor peribiliary plexus, leading to inadequate preservation of the bile ducts and posttransplant BSs. To test this hypothesis, we retrospectively compared the incidence of BSs in 2 groups of adults undergoing LT using different types of aortic preservation solution in the donor: group 1 (n = 24), low-viscosity (LV) Marshall solution; and group 2 (n = 27), HV University of Wisconsin (UW) solution. All donors in both groups received additional portal flushes with UW. All LTs were performed between November 1995 and August 1998 at 2 centers by the same surgeon, eliminating a technical bias. Terminal duct-to-duct anastomosis was performed in all recipients except 1 patient in group 1, who underwent a bile duct-to-jejunum anastomosis. BSs were first suspected on clinical and biochemical grounds and then confirmed by endoscopic retrograde cholangiopancreatography. Identical medical protocols were used in all patients. One-year patient survival rates in groups 1 and 2 were 92% and 100%, respectively (P =.9). One-year graft survival was identical to patient survival. The incidence of BSs in group 1 was 4.1% (1 of 24 patients), compared to 29.7% in group 2 (8 of 27 patients; P =.02). The BS in group 1 occurred 4 months post-LT and was anastomotic. BSs in group 2 occurred between 1 and 12 months post-LT and were anastomotic, extrahepatic, intrahepatic, or combined intrahepatic and extrahepatic. There were no significant differences in the following factors between groups 1 and 2: donor age, local versus imported liver, split-liver or full-liver transplantation, incidence of multiple vessels in the donor liver, indications for LT, recipient age, T-tube versus no T-tube, post-LT peak aspartate aminotransferase level, and treatment for rejection. There was no hepatic artery thrombosis or primary nonfunction in either group. Interestingly, cold ischemia time (CIT) was longer in group 1, which had the least incidence of BSs (692 +/- 190 v 535 +/- 129 minutes in group 2; P =.001). Follow-up was longer in group 1 (28.9 +/- 8.3 v 15.6 +/- 8 months in group 2; P =.0001). Preservation costs per procurement were 1.9 times greater in the UW group than in the Marshall group. Donor aortic flushing with an HV preservation solution leads to more frequent BSs compared with an LV preservation solution. The impact of preservation solution outweighs the previously described deleterious impact of prolonged CIT. Mixed preservation solution (Marshall solution in the aorta, UW solution in the portal vein) might protect against BS formation while providing optimal liver graft preservation, function, and survival despite a mean CIT longer than 10 hours.

Orthotopic liver transplantation for alcoholic liver disease: a retrospective analysis of survival, recidivism, and risk factors predisposing to recidivism.

The aim of this study performed at the Liver Unit at the Queen Elizabeth Hospital, Birmingham, UK, is to assess posttransplantation alcohol consumption and identify risk factors associated with recidivism. This retrospective case-control study used a self-report questionnaire to assess pretransplantation and posttransplantation drinking, and a retrospective cohort study used patient notes to analyze risk factors for recidivism. Of 64 patients who underwent transplantation for alcoholic liver disease (ALD) between May 1996 and November 1999, a total of 49 surviving patients (40 men, 9 women) were available for study. The comparison group consisted of 49 patients matched for age, sex, and date of transplantation who underwent transplantation for non-alcohol-induced chronic liver disease. Two-year patient survival rates were 82% in both study groups. The questionnaire response rate was 69.3% and 75.5% in patients with and without ALD, respectively. Data on recidivism (defined as any alcohol consumption after transplantation) were available in 46 of the 49 patients with ALD. Of these, 45.6% were drinking; 21.7% reported only occasionally drinking; 17.3%, moderate drinking; and 6.5%, heavy drinking. Information on alcohol consumption was available from 41 of the 49 controls. Of these, 52.5% consumed alcohol; 22.0% reported drinking only on special occasions; 24.4%, moderate drinking; and 4.9%, a return to heavy drinking. However, these differences were not statistically significant, and log-rank analysis found no significant difference in time to resumption of drinking. In the ALD cohort, no significant risk factors were identified to predict recidivism. No pretransplantation risk factors (including period of abstinence before transplantation) correlated with recidivism. Survival after transplantation for ALD is similar to that in other forms of chronic liver disease. Recidivism rates for patients with ALD are high, but patients with ALD do not drink more than their control counterparts posttransplantation. In most instances, alcohol consumption posttransplantation is minimal to moderate (<20 units/wk) and seems to be controlled.

Liver transplantation for polycystic liver disease.

Polycystic liver disease (PLD) may provoke massive hepatomegaly and severe physical and social handicaps. Data on orthotopic liver transplantation (OLT) for PLD are rare and conflicting. Conservative surgery (resection or fenestration) is indicated for large single cysts, but its value for small diffuse cysts is questionable. In addition, conservative surgery is not devoid of morbidity and mortality. OLT offers the prospect of a fully curative treatment, but controversy remains because those patients usually have preserved liver function. Thus, we reviewed our experience with OLT for PLD. Sixteen adult women underwent OLT for small diffuse PLD between 1990 and 1999. Mean age was 45 years (range, 34 to 56 years). Fourteen patients had combined liver and kidney cystic disease, but only 1 patient required combined liver and kidney transplantation, whereas 13 patients underwent OLT alone. Two patients had isolated PLD. Indications for transplantation were massive hepatomegaly causing physical handicaps (n = 16), social handicaps (n = 16), malnutrition (n = 4), and cholestasis and/or portal hypertension (n = 5). OLT caused no technical difficulty in 15 of 16 patients (surgery duration, 6.8 hours; range, 5 to 8 hours), with blood transfusions of 7.9 units (range, 0 to 22 units). One patient who underwent attempted liver-mass reduction pre-OLT died of bleeding and pulmonary emboli. Native liver weight was 10 to 20 kg. Posttransplantation immunosuppression consisted of cyclosporine or FK506, azathioprine, and steroids (discontinued at 3 months). Morbidity included biliary stricture (2 patients), revision for bleeding and hepatitis (1 patient), pneumothorax and subphrenic collection (1 patient), and tracheostomy (1 patient). One patient died of lung cancer 6 years posttransplantation. Both patient and graft survival rates are 87.5% (follow-up, 3 months to 9 years). Of 15 patients who underwent OLT alone, only 1 patient needed a kidney transplant 4 years after OLT. Kidney function has remained satisfactory in the other patients despite the use of cyclosporine or FK506 (last follow-up creatinine level, 1.55 mg/dL; range, 0.80 to 2.85 mg/dL). OLT had a dramatic impact on daily quality of life, enabling these patients to go back to a fully active life style. OLT offers the chance of a definitive treatment in patients with extensive, small, diffuse PLD that has evolved into severely handicapping hepatomegaly. In contrast to previous studies, combined liver and kidney transplantation is rarely needed. Patient symptoms and chances of definitive palliation offered by OLT must be balanced against the risks of transplantation and lifelong commitment to immunosuppression.
