The authors suggest that occlusion of blood flow to the whole liver is not necesarily a routine procedure in surgical removal of giant cavernous hemangioma in the 8th segment of liver. An occlusion tape can be placed around the finferior vena cava inadvance. Separtion of inferior vena cava between the diaphragm and the upper surface of liver sometimes is difficult, so that placement of the tape may fail. The procedure which we performed in four patients was intermittent occlusion of blood flow at the first hepatic hilum at room temperature during dissection and removal of the tumor en bloc. This operative method is simple and safe as compared with that of resection of the 8th segment of liver.
Objective To evaluate the outcome of liver transplantation in patients with recurrent liver cancer after resection. Methods Data of 23 patients underwent liver transplantation for recurrent liver cancer from April 2001 to March 2008 were retrospectively collected and analyzed. Results Previous history of liver resection had little negative effect in subsequent liver transplantation in technical aspect. Liver function recovered uneventfully after transplantation in all cases. Alpha fetoprotein (AFP) recovered to normal value in 13 of 17 cases with elevated AFP before transplantation within one month after operation. Five cases (21.74%) had postoperative complications. Nineteen cases (82.61%) were followed up, average follow-up duration were 610 days. There were 5 cases (26.32%) of cancer recurrence and 6 deaths during follow-up, survival rate was 68.42%. Conclusion Liver transplantation is a reasonable treatment for recurrent liver cancer after resection.
ObjectiveTo figure out the factors affecting the prognosis of liver transplantation and the research progress on methods for predicting the prognosis of liver transplantation so as to provide guidance and reference for the distribution of liver sources and the perioperative treatment of liver transplantation.MethodThe literatures related to the factors influencing the prognosis of liver transplantation and the methods in predicting the prognosis were searched in the PubMed, CNKI, Wanfang, and other databases and the results were analyzed and summarized.ResultsThe liver transplantation was an effective method in the treatment of end-stage liver diseases. The main factors affecting the prognosis of liver transplantation included the change of internal environment, systemic inflammatory response, and general systemic conditions. On the basis of Model for End-stage Liver Disease (MELD), the new prediction model built in combination with the blood sodium ion, lactate, muscle mass, or reticulocyte count and hemoglobin concentration had improved the prognostic prediction ability of liver transplantation.ConclusionsIt is possible to predict the prognosis of patients with liver transplantation more accurately by selecting a more targeted prediction model combined with the factors affecting the prognosis of liver transplantation. It might provide a reference for perioperative management and treatment and make the limited liver source play the most role and save more lives.
Objective To evaluate safety and long-term efficacy of fully covered self-expandable mental stent (FCSEMS) in treatment of biliary stricture after liver transplantation (LT). Methods From January 2010 to June 2018, the data of patients with the biliary stricture after the LT underwent the endoscopic retrograde cholangiagraphy (ERCP) at the First Hospital of Lanzhou University were collected retrospectively. The therapeutic effect of the FCSEMS was evaluated. Results A total of 21 patients with the biliary stricture after the LT were treated. The success rate of the stent placement was 100%. The FCSEMSs were used in 7 cases and the only multiple plastic stents (MPSs) were used in 14 cases. There were no significant differences in the gender, age, time of biliary stricture, frequency of ERCP, recurrence time of biliary stricture, cure time of biliary stricture, curative effect, recurrence of biliary stricture, and incidence of complications between the patients treated with the FCSEMS and the MPS (P>0.050), but the number of plastic stents in the patients treated with the FCSEMS was significantly less than that in the patients treated only with the plastic stents (P<0.050), while the duration of stent retention was longer than that in the patients treated only with the plastic stents (P<0.050). Six patients were cured, 1 was remitted, and 2 were relapsed by the FCSEMS. Eight were cured, 3 were remitted, 3 were ineffective, and 5 were relapsed by the MPS alone. Conclusions FCSEMS might be an safe effective alternative to plastic stent in treatment of biliary stricture after LT, resulting in a longer duration placement, less number of plastic stent use. It is necessary to further accumulate cases to validate cure rate and recurrence rate of biliary stricture.
目的研究依達拉奉影響肝臟缺血再灌注過程中TNF-α的表達情況，探討依達拉奉對肝臟缺血再灌注損傷的逆轉作用。 方法將80只Wistar大鼠編號，根據計算機產生隨機數字，前40為一組，后40為一組，分為實驗組和對照組2組，建立常溫下部分肝缺血再灌注損傷動物模型。 在肝臟缺血再灌注損傷開始前1 h和開始時對實驗組大鼠給予依達拉奉注射液10 ml，對照組則給予同等容量的生理鹽水。分別于再灌注后0、1、2及4 h測定肝臟脂質過氧化物酶（LPO）和肝臟谷草轉氨酶(AST) 濃度； 應用RT-PCR法檢測肝組織TNF-α mRNA含量，并測定肝組織和血清中TNF-α水平； 應用TUNEL染色法檢測缺血肝組織的細胞凋亡情況。結果再灌注后1、2及4 h，實驗組大鼠肝臟LPO及AST濃度均明顯低于對照組（Plt;0.001）； 實驗組再灌注后1 h時肝組織TNF-α mRNA表達量、肝組織和血清TNF-α含量均明顯升高且達峰值，但均明顯低于對照組（Plt;0.05）； 再灌注后各時相實驗組肝細胞凋亡率明顯升高，但均明顯低于對照組（Plt;0.05）。 結論依達拉奉能抑制氧化應激反應，從而降低肝缺血再灌注損傷； 并顯著減少炎性細胞因子TNF-α的產生，抑制炎性反應的發生，減少肝細胞的凋亡。
Objective To investigate the value of multislice spiral CT （MSCT） findings in the diagnosis of hepatic tuberculosis. Methods MSCT imaging data, including both plain and contrast-enhanced CT scan, of 14 patients with hepatic tuberculosis confirmed by surgery (5 patients), aspiration biopsy (4 patients), or clinic follow-up (5 patients) were collected for the study. MSCT findings were analyzed with correlation of pathological changes. Results Hepatic tuberculosis was classified into 2 types. ①The parenchymal type (12 patients), which was further divided into 4 subtypes: Miliary subtype (2 patients) showed multiple tiny hypodense dots with faint border and had no enhancement; Nodular subtype (5 patients) showed blurring border on plain CT scan, 2 patients had no enhancement, 2 had peripheral rim-like enhancement, and peripheral rim enhancement mixed with no enhancement in 1 patient; Abscess subtype (4 patients) showed central hypodense area with peripheral zone-like enhancement in 2 patients, or patchy like slight enhancement in 2 patients; Fabric and calcific subtype (1 patient) depicted enplaque calcification. ②The serohepatic type (2 patients) showed thickened hepatic capsule, sub-capsule nodules with slight enhancement, and local subcapsular fluid collection. Other signs included hepatomegaly, tuberculous lymphadenopathy, splenic tuberculosis, and tuberculosis of pancreas, adrenal glands, intestine and thorax. Conclusion MSCT plays an important role in diagnosis of hepatic tuberculosis, by reflecting underlying pathological changes.
