Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.

Objective To evaluate the feasibility,safety and efficacy of laparoscopic radiofrequency ablation (RFA) therapy for hepatocellular carcinoma (HCC).Methods Sixty-eight cases of liver cancer lesions were underwent laparoscopic radiofrequency ablation,and their postoperative recovery state,focal necrosis rate were observed.Results All the 68 cases were successfully performed operation,114 lesions were treated including 20 missed lesions at preoperative imaging diagnosis.There were no serious postoperative complications,the average hospital stay was (2.5 ± 1.2) days,focal necrosis rate 3 months after operation was 85.9％,lesion recurrence rate 6 months after operation was 12.2％,the 1-year survival rate was 76.47％.Conclusions Laparoscopic radiofrequency ablation in treatment of hepatocellular carcinoma has high security,few complications,short hospital stay and remarkable clinical effects.It's well worth clinical outreach.

ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.

Objective To evaluate the outcome of living donor liver transplantation(LDLT)for hepatocellular carcinoma(HCC).Methods We retrospectively analyzed the clinical data of 180 patients,who had received LDLT(n=34)or deceased donor liver transplantation(DDLT,n=146)for HCC,compared overall and recurrence-free survival between LDLT and DDLT,and identified the risk factors of tumor recurrence and prognosis by univariate and multivariate analysis.Results The 5-year overall survival and recurrence-free survival rate were 53 % and 58 %,respectively,in DDLT group,and 60 % and 60 %,respectively,in LDLT group.There was no significant difference in overall (P=0.85)and recurrence-free(P=0.89)survival between these two groups.The tumor recurrence rate was 26.5 % in LDLT group,and 17.8 % in DDLT group,respectively(P=0.25).Multivariate COX regression model analysis identified vascular invasion(relative risk 2.118,95 % confidential interval 1.201-4.353,P=0.032)and tumor beyond UCSF criteria(relative risk 3.490,95 % confidential interval 1.862-8.207,P=0.015)as independent risk factors of tumor recurrence,and tumor beyond UCSF criteria(relative risk 8.573,95 % confidential interval 3.016-18.261,P=0.006)as independent predictors of prognosis.Conclusion LDLT is a safe and effective procedure for patients with HCC,but further studies are required for selection criteria of recipients and higher HCC recurrence rate after LDLT.

BACKGROUNDTo compare the effect and toxicity between gemcitabine and cisplatin (GP) with vinorelbine, ifosfamide and cisplatin (NIP) combined chemotherapy in the treatment of patients with advanced non-small cell lung cancer (NSCLC).

METHODSEighty patients received either gemcitabine 1 000 mg/m² on days 1, 8, or 15 plus cisplatin 70-80 mg/m² on day 1, or vinorelbine 25 mg/m² on days 1, 8, ifosfamide 1.2 g/m² on days 1-4 plus cisplatin 70-80 mg/m² on day 1, every 28 days as a cycle.

RESULTSThe objective response rate was 40.0% in GP goup, compared with 52.5% in NIP group (P > 0.05). Median survival time of GP and NIP groups was 13.68 and 15.34 months respectively, and 1-year survival rates were 54.29% and 59.46% respectively (P > 0.05). Leukopenia at grade III+IV was significantly lower in GP arm (27.5%) than that in NIP arm (55.0%) (P < 0.05). Non-hematological toxicities were less frequent in GP group than those in NIP group (P < 0.05).

CONCLUSIONSAlthough the response rate tends to be higher in three-drug than in two-drug combined chemotherapy, but no significant difference is observed. Three-drug combinations often result in more toxicities. Two-drug combination GP may be the standard protocol for chemotherapy of advanced NSCLC. Three-drug combination NIP should be given to young patients with good performance status.

Objective To optimize plan for right lobe living donor hepatectomy based on the territorial volume drained by the middle hepatic vein (MHV) as shown by preoperative MR image in donors.Methods Utilizing preoperative MR dynamic enhancement scanning image,virtually plot three types of hepatic parenchyma transsection plane based on the variation of including MHV for right lobe graft procurement. Results From June 2006 to May 2010,65 adult-to-adult right lobe living donor liver transplantations was performed at General Hospital of Chinese PLA,in which there were 43 grafts including MHV (66.2％,43/65 ), eight grafts including partial MHV which was dissected before the V4b abouchement ( 12.3％,8/65) and 14 grafts not including MHV (21.5％,14/65). There was no postoperative death in donors and the postoperative complications developed in 10.76％ (7/65). The recipients' perioperative mortality was 7.69％ (5/65). Ttwenty-one complications developed in 18 recipients,and the morbidity was 32.31％. The cumulative survival rates were 86％,77％ and 68％respectively for 1,2 and 3 years. Conclusions The optimizing liver resection plane could be practically designed preoperatively for right lobe graft procurement based on the territorial volume drained by MHV.

Objective:To study the correlation between umbilical artery blood gas (UABG) and Apgar score of neonates and the risk factors of low base excess (BE) in UABG.Methods:From March 2017 to September 2020, newborns without congenital malformation born in three hospitals were prospectively enrolled and received UABG analysis. According to their Apgar score, the infants were assigned into low Apgar score group and normal Apgar score group. According to BE of UABG, they were assigned into BE<-12 mmol/L group and BE≥-12 mmol/L group. The UABG indexes including abnormal pH and BE between the low Apgar score group and the normal Apgar score group were compared. The risk factors of low BE in UABG were analyzed.Results:A total of 1 351 qualified samples were included including 208 cases in low Apgar score group and 1 143 cases in normal Apgar score group. 115 cases were in BE <-12 mmol/L group and 1 236 cases in BE ≥-12 mmol/L group. The incidences of abnormal pH and BE values in the low Apgar score group were higher than the normal Apgar score group [50.0% (104/208) vs. 13.8% (158/1 143), 34.6% (72/208) vs. 3.8% (43/1 143)]. The pH and BE values of UABG were positively correlated with 1 min Apgar score ( r=0.402, 0.398, P<0.001). Multivariate logistic regression analysis indicated that the risk factors for BE<-12 mmol/L were Ⅲ° contaminated amniotic fluid ( OR= 3.155, 95% CI 1.972~5.025, P<0.001) and placental abruption ( OR = 3.968, 95% CI 1.992~7.874, P <0.001). Conclusions:The pH and BE values of neonatal UABG are positively correlated with 1 min Apgar score. Ⅲ° contaminated amniotic fluid and placental abruption are risk factors of low BE in UABG.
