    Alleviating the Burden of Small-for-Size Graft in Right Liver Living Donor Liver Transplantation Through Accumulation of Experience

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2010

    The issue of small-for-size graft (SFSG) containing the middle hepatic vein in right liver living donor liver transplantation from 1996 to 2008 (n = 320) was studied. Characteristics of donors, grafts and recipients were comparable between Era I (first 50 cases) and Era II (next 270 cases) except that the median model for end-stage liver disease (MELD) score was higher in Era I (29 vs. 24; p = 0.024). The median graft to standard liver volume ratio (G/SLV) in Era I was 49.0% (range, 32.8,86.2%), versus 49.3% (range, 28.4,89.4%) in Era II (p = 0.498). Hospital mortality rate, the study endpoint, dropped from 16.0% (8/50) in Era I to 2.2% (6/270) in Era II (p = 0.000). Univariate analysis showed that MELD score (p = 0.002), pretransplant hepatorenal syndrome (p = 0.000) and Era I (p = 0.000) were significant in hospital mortality. Logistic regression analysis showed that only Era I (relative risk 9.758; 95% confidence interval, 2.885,33.002; p = 0.000) was significant. In Era I, G/SLV<40% had a relative risk of 7.8 (95% confidence interval, 1.225,49.677; p = 0.030). The hospital mortality rates for G/SLV<40% were 50% (3/6) and 1.9% (1/52) in Era I and II respectively. In conclusion, through accumulation of experience, SFSG became less important as a factor in hospital mortality. [source]

    Percutaneous drainage of hydatid cyst of the liver: long-term results

    Background Previously surgical operation was the only accepted treatment for hydatid liver cysts. Recently percutaneous management has become more preferable because of its low morbidity rate and lower cost. Patients and methods In all, 101 patients harbouring 120 hydatid cysts of the liver were treated by percutaneous drainage between October 1994 and December 1997. Of these cysts, 89 were in the right liver and 31 in the left liver. Thirty-one patients had had previous operations for hydatid disease. All cysts had an anechoic or hypoechoic unilocular appearance on ultrasound scan. The mean dimension of the cysts was 7.5 ± 2.9 cm (range 3,10.4 cm). All patients received oral albendazole 10 mg/kg perioperatively. After aspiration under sonographic guidance, cysts were irrigated with 95% ethanol. Results The amount of cyst fluid aspirated was 220 ± 75 ml and the amount of irrigation solution used was 175 ± 42 ml. Four patients developed mild fever and three had urticaria. Mean length of hospital stay was 2.1 ± 0.7 (range 1,4) days, and patients were followed up for 43,62 months (mean 54 ± 5.4 months). Maximal cyst diameter decreased from 7.5 ± 2.9 cm to 3.2 ± 15 cm (p<0.001). Sonographic examinations revealed high-level heterogeneous echoes in the cyst cavity (heterogeneous echo pattern), while the cyst cavity was completely obliterated by echogenic material (pseudotumour echo pattern). Discussion Most hydatid cysts of the liver can be managed successfully by acombinationof drugtherapyand percutaneous drainage. [source]

    Advances in adult living donor liver transplantation: A review based on reports from the 10th anniversary of the adult-to-adult living donor liver transplantation meeting in Tokyo

    LIVER TRANSPLANTATION, Issue 6 2004
    Yasuhiko Sugawara
    In 1993, the Shinshu Group performed the first successful adult-to-adult living donor liver transplantation (LDLT). During the first 10 years of LDLT, many technical innovations have been reported. The major limitation of LDLT for adult recipients is the size of the graft. To overcome the problem, several graft types were designed, including left liver graft with caudate lobe, right liver, modified right liver, and right lateral sector and dual grafts. The necessity and criteria of reconstruction of middle hepatic vein is still on debate in right liver graft without trunk of middle hepatic vein. Biliary reconstruction remains a significant source of morbidity in LDLT. Donor safety must always be the primary consideration in LDLT and the selection criteria and management of the living donor must continue to be refined. On February 21, 2004, the 10th anniversary of the adult-to-adult LDLT meeting was held in Tokyo to review the accumulated experience and the presented information is summarized.

    Hepatic Resection in Liver Transplant Recipients: Single Center Experience and Review of the Literature

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2005
    Olaf Guckelberger
    Biliary complications such as ischemic (type) biliary lesions frequently develop following liver transplantation, requiring costly medical and endoscopic treatment. If conservative approaches fail, re-transplantation is most often an inevitable sequel. Because of an increasing donor organ shortage and unfavorable outcomes in hepatic re-transplantation, efforts to prolong graft survival become of particular interest. From a series of 1685 liver transplants, we herein report on three patients who underwent partial hepatic graft resection for (ischemic type) biliary lesions. In all cases, left hepatectomy (Couinaud's segments II, III and IV) was performed without Pringle maneuver or mobilization of the right liver. All patients fully recovered postoperatively, but biliary leakage required surgical revision twice in one patient. At last follow-up, two patients presented alive and well. The other patient with persistent hepatic artery thrombosis (HAT), however, demonstrated progression of disease in the right liver remnant and required re-transplantation 13 months after hepatic graft resection. Including our own patients, review of the literature identified 24 adult patients who underwent hepatic graft resection. In conclusion, partial graft hepatectomy can be considered a safe and beneficial procedure in selected liver transplant recipients with anatomical limited biliary injury, thereby, preserving scarce donor organs.

    Tailoring the Type of Donor Hepatectomy for Adult Living Donor Liver Transplantation

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2005
    Norihiro Kokudo
    Donor hepatectomies for adult living donor liver transplantations were performed in 200 consecutive donors to harvest a left liver (LL) graft (n = 5), a LL plus caudate lobe (LL + CL) graft (n = 63), a right liver (RL) graft (n = 86), a RL and middle hepatic vein (RL + MHV) graft (n = 28) or a right lateral sector (RLS) graft (n = 18). The graft type was selected so that at least 40% of the recipient's standard liver volume was harvested. No donor deaths occurred, and no significant differences in the morbidity rates among either donors or recipients were observed when the outcomes were stratified according to the graft type. Donors who donated RL exhibited higher values of serum total bilirubin and prothrombin time than those who donated non-RL (LL, LL + CL, RLS) grafts. The time taken for hilar dissection and parenchymal transection increased in the following order: RLS graft, LL graft and RL graft harvesting. In conclusion, non-RL grafting was more time consuming, but the hepatic functional loss in the donors was smaller. Our graft selection criteria were useful for reducing the use of RL grafts with acceptable morbidity in both donors and recipients. [source]
