Objective To retrospectively evaluate the MR and CT features of delayed complications of hepatic rupture and clinical management.Methods Delayed complications developed in 8 of 20 patients with hepatic rupture 1～3 weeks after surgery.7 patients were managed with PTD and one with laparotomy.MRI and CT were followed-up before and after treatment.Results Delayed complications included 3 bilomas,3 recurrent bleedings and 2 abscess,which appeared characteristic bi-directional changes of the signal intensity on T 1-weighted image and were non-specific on T 2-weighted image(hyperintense)and CT (low-density).Conclusion T 1-weighted images appeared to be more effective than T 2-weighted images and CT in the differentiation of delayed complications from subacute intrahepatic hematoma.Followed-up MRI and CT are needed in patients with deeptype hepatic rupture in the first month after injury.PTD and laparotomy are helpful in management of biloma and abscess and nonuseful in patient with inactive recurrent bleeding.

Objective To analyze the clinical diagnosis and treatment strategies of liver-localized posttransplantation lymphoproliferative disease (LL-PTLD).Methods Six cases of LL-PTLD from more than 3000 cases of liver transplant recipients from July 2003 to July 2011 were retrospectively analyzed.Other six cases of LL-PTLD were retrieved through Pubmed and Wanfang.The diagnosis and treatment of 12 cases of LL-PTLD were summarized and analyzed.Results All patients with LL-PTLD were diagnosed pathologically.The incidence of LL-PTLD was 0.2％ (6/3000).Among 12 patients,immunosuppressant and anti-EB virus treatment was reduced or withdrawn in the vast majority of patients,and treatment response was satisfactory.Systemic chemotherapy was given in 6 cases,and three of them died.Local radiation therapy was given in 4 cases,the tumor was significantly controled,and patients survived.Secondary liver transplantation was performed on 3 cases: 1 case died of recurrent lymphoma,and one case received partial hepatectomy and no lymphoma recurred.Conclusion For cases with obstructive symptoms of fever and chills associated with jaundice without reasonable explanation,LL-PTLD is suspected and diagnosed by liver biopsy.Basic treatments such as adjustment of immunosuppressive agents and anti-viral therapy are recommended as early as possible.Local radiation therapy is a treatment method of LL-PTLD,which can obtain a satisfactory therapeutic effect.

Objective Small-for-size syndrome (SFSS) is a common and serious problem after living donor liver transplantation (LDLT) of small grafts.To prevent SFSS by selecting large enough graft,enlarging outflow tract,and controlling the portal vein pressure and flow during LDLT.Methods 113 adult LDLT recipients were reviewed from Dec.1,2007 to Nov.30,2009.Enlarging the portal outflow tract by the incision of the anterior rim of the orifice of the right hepatic vein (RHV),modificating graft inflow,and selecting large enough graft were done to prevent SFSS.The relationship between the patients' GRWR,portal vein flow,portal vein pressure and the occurrence of SFSS was analyzed.Results All patients received the outflow orifice modification.The portal vein pressure and the portal vein flow were decreased after spleen artery ligation.No SFSS ocurred.Conclusion Selecting large enough liver graft,and enlarging portal vein inflow and outflow were safe for the LDLT recipients,and can effectively prevent SFSS.

Objective To evaluate the effect of aged cadaveric donor liver on long-term survival of liver transplant recipients.Methods Patients who underwent first time liver transplantation from cadaveric donor aging above 40 years were studied.Those patients were divided into donor age ＜ 50 group and age ≥ 50 group.Data for donor graft,recipient perioperative condition as well as long-term survival of recipients were compared between the two groups.Results There were 21 recipients receiving liver graft from a donor aging ≥ 50 (54.6-± 3.9) years.58 cases were given a liver graft from a donor aging ＜ 50 years (42.6 ± 2.9).The overall donor graft conditions were not different between the two groups (P ＞ 0.05).However,the median amount of operation time in donor age ≥50 group was longer than that in age ＜ 50 group (9.5 h vs.8.0 h,Z =-1.994,P =0.046).Median red blood cell (RBC) transfusion volume was greater in the age ≥50 group than that in age ＜50 group (1 000 ml vs.800 ml,Z =-2.593,P =0.010).During the follow-up,graft survival rates in 1,3 and 5 years were 74％,55％,55％ in donor age ≥50 group and 87％,66％,63％ in donor age ＜ 50 group,respectively (Z =0.903,P =0.342).Conclusions Use of aging cadaveric donor liver expandes donor pool,and is as well as safe,not hindering in graft's long term functions.

Objective To summarize the experience of reconstruction of Ⅴ and Ⅷ hepatic veins in right lobe (without middle hepatic vein) living donor liver transplantation. Methods The clinical data of 55 cases of living donor liver transplantation of right lobe without middle hepatic vein were analyzed, and Ⅴ and Ⅷ hepatic veins were reconstructed. All donors underwent evaluation on the basis of vascular anatomy, GRWR and graft volume/ESLV. Fifty-one grafts underwent reconstruction of Ⅴ and Ⅷ hepatic veins with cold-storage cadaveric iliac veins. Great saphenous vein, varicose umbilical veins, recipient intrahepatic portal veins and recipient intrahepatic veins were used respectively in the remaining 4 cases. Results One recipient died of obstruction of out-flow on the postoperative day 43. One recipient was converted to cadaver donor liver transplantation at the 7th day after operation, because of acute liver function failure. The remaining 53 cases recovered successfully. Conclusion Reconstruction of Ⅴ and Ⅷ hepatic veins with proper materials in right lobe (without middle hepatic vein) living donor liver transplantation is feasible, and the effect is satisfactory.

Objective To evaluate biliary digital imaging technology in determining the type of the intrahepatic bile duct anatomy and the transection plane of the duct in right lobe living donor liver transplantation(LDLT). Methods Mobile digital subtraction angiography was performed to show the intrahepatic bile duct anatomy of 66 liver transplant donor candidates. Combined with metal markers, the bile duct transection plane was defined. Comparing with the actual results, the effect of digital imaging technology in determining the intrahepatic anatomical variations and transection plane of the duct in LDLT was evaluated. Results Intrahepatic bile duct anatomical variations were showed in all donors by using digital imaging technology. type Ⅰ (classical type) was identified in45 cases (68.2%), type Ⅱ (with triple confluence, the simultaneous emptying of the right anterior segmental duct, right posterior segmental duct and left hepatic duct into the common hepatic duct) in 7 cases ( 10.6% ), type Ⅲ (no right hepatic duct stem, right posterior segmental duct draining into common hepatic duct) in 13 cases ( 19. 7% ), type Ⅳ (no right hepatic duct stem, right posterior segmental duct draining into left hepatic duct) in 1 case (1.5%), and type Ⅴ (complex variation ) in no case (0%). As a result, cases of type Ⅰ form a single anastomosis. In type Ⅱ, four cases formed double anastomoses, three cases formed single anastomosis with or without ductoplasty. In type Ⅲ, two anastomoses were formed in 9 cases, single anastomosis in 4 cases with ductoplasty. The case of type Ⅳ had double anastomoses. In all cases right lobe liver were harvested.Conclusions Biliary digital subtraction image combined with metal markers accurately defines intrahepatic bile duct anatomy and the transection plane, helping to reduce number of bile duct anastomosis, and contributes to safe graft harvesting.

Objective To probe the correlation between preoperative pulmonary dysfunction and postoperative pulmonary complications in patients of orthotopic liver transplantation. Methods From August 2008 to June 2009, 71 orthotopic liver transplantation patients were studied. Preoperative pulmonary function and its relationship with postoperative pulmonary complications were analyzed.Results Preoperatively 65 out of 71 patients had abnormal lung functions, suffering from pulmonary diffusing capacity reduction (65 cases, 91.5% ), followed by reduction of restrictive ventilation function (30 cases, 42. 2% ), small airway function reduction ( 28 cases, 39.4% ), and obstructive ventilatory function reduction (21 cases, 29. 6% ). The incidence of postoperative pulmonary complications was 56. 3% including: pulmonary atelectasis, pneumonia, acute respiratory failure. The incidence of posttransplantation pulmonary complications in patients with pulmonary restrictive or obstructive ventilation function reduction was higher than in normal group (x2 = 6.703, P= 0.010; x2 = 4.768, P = 0.029), and there was significant difference in pulmonary complication rate between groups of moderate and severe diffusing capacity reduction and mild reduction and normal range (x2 = 8.478, P = 0.004 ).Conclusions Preoperative pulmonary function abnormality in patients before liver transplantation such as pulmonary ventilatory function reduction (VCmax ＜ 80% or FEV1.0 ＜ 80% ) and moderate to severe pulmonary diffusing capacity reduction (TLCOSB ＜ 60% ) predicts higher incidence of postoperative pulmonary complications.
