Objective To summarize the initial experience in adult-to-adult living donor liver transplantation(ALDLT),so as to improve the efficacy of ALDLT.Methods The clinical data of 31 adult patients who undelwent ALDLT from June 2006 to February 2008 were retrospectively analyzed.Results Of all the patients,8 was with decompensated cirrhosis,7 with acute liver failure,12 with hepatocellular carcinoma,2 with purpura of liver,1 with hilar cholangiocarcinoma,and 1 with Wilson disease.The liver grafts included 25 right lobes with middle hepatic vein(MHV),3 right lobes without MHV,1 right lobe with MHV+left lateral lobe,1 right lobe with MHV+left lobe.The remaining 1 patient underwent auxiliary partial orthotopic liver transplantation with left lobe graft.Six post-transplantation complications occurred in 5 donors. Eleven post-transplantation complications occurred in 9 recipients,including 4 biliary complications,3 vascular complications,3 infection complications and 1 delayed healing of the incision.After ALDLT,2 recipients died of pulmonary infection and 1 of multiple aspergillus infection. Conclusions ALDLT has become an effective method to expand the source of liver grafts.Rational donor and recipient assessment,surgical procedure and postoperative management are key to ALDLT.

OBJECTIVE To discuss the preventive methods of hepatitis B virus reinfection after liver transplantation. METHODS Eighty eight liver transplantation recipients with HBV-related end-stage liver diseases including chronic fulminant hepatitis B,end-stage liver cirrhosis and liver carcinoma were analyzed retrospectively,and were given lamivudine pre-transplantation to prevent hepatitis B virus reinfection.Post-transplantation medicines of lamivudine were administered in 3 cases;lamivudine and hepatitis B immunoglobulin(HBIg) in 85 cases.The follow-up criteria included serum HBV,HBV-DNA,liver biopsy,immunohistochemical study of liver biopsy specimens and clinical manifestations.All of patients were followed-up 6 months at least.RESULTS Two of the three cases who taken lamivudine developed reinfection,the little time is 6 months following liver transplantation.There were three of eighty five cases taken lamicudine and HBIg(small dosage) developed reinfection.CONCLUSIONS Liver transplantation is an effective treatment for HBV-related end-stage liver diseases.Given lamivudine at the pre-transplantation could reduce the levels of the HBV virus copies.Lamivudine and HBIg post-transplantation offer effective prevention against hepatitis B virus reinfection.

OBJECTIVE To explore the treatment measure of pulmonary infection after liver transplantation.METHODS The clinical data of 78 cases of pulmonary infection after liver transplantation in our hospital were analyzed retrospectively.RESULTS The incidence of pulmonary infection in this group of patients was 48.8%.The mean onset time of the first pulmonary infection after operation was(9.56?5.53)days after surgery.Forty four patients were diagnosed as right pneumonia,14 as left pneumonia,and 20 bilateral pneumonia.Long operation time,mechanical ventilatory time,abdominal bleeding,intraoperative total fluid perfusion and renal dysfunction after liver transplantation were risk factors of pulmonary infection.87.2% Of these patients improved,and 12.8% died.CONCLUSIONS The mortality of pulmonary infection after liver transplantation is high.Bacteria and fungi are the major pathogens.The key of prevention and cure of pulmonary infection after liver transplantation wis included of cutting down operation time,lessening abdominal bleeding,controlling intraoperative fluid perfusion,extubating as soon as possible,protecting renal dysfunction and raising pathogeny to check.

OBJECTIVE To evaluate the effect of lamivudine on prophylaxis against hepatitis B virus(HBV) reinfection following orthotopic liver transplantation(OLT).METHODS The clinical data of 14 CLT recipients with HBV-related diseases received lamivudine(100mg/day) were retrospectively analyzed in our hospital.Hepatitis B serum markers,serum HBVDNA,and YMDD district variation were detected every two weeks.HBsAg and HBcAg in the liver specimens were examined by immunohistochemistry.Liver biopsy was conducted from the donor during operation and from the recipient postoperatively in a regular interval.RESULTS The reinfection took place in 4 patients and postoperatively(28.6%),HBV-DNA was transfered to the positive in 2 cases,and among them was 1 YMDD district produced and made a variation. Two cases with positive HBV-DNA before liver transplantation had higher HBV reinfection rate postoperatively.CONCLUSIONS Lamivudine monotherapy can effectively and definitely;preven HBV reinfection after liver transplantation HBV reinfection can produce YMDD district and make a variation again;HBV relevant diseases patient should negatively turn the HBV-DNA at the time of competent liver transplantation.

Objective To study the clinical efficacies of different surgical palliative treatments for patients with advanced pancreatic carcinoma.Methods A retrospective analysis was conducted on the clinical data of 119 patients with advanced pancreatic carcinoma who were treated in the department of General Surgery of Linyi's Central Hospital from January 2010 to January 2016.According to the different surgical methods the patients received,they were divided into the seed group (n =38),the radiofrequency ablation (RF) group (n =52) and the control group (n =29).Patients' general data,operation data,postoperative complications and follow-up profiles were analyzed.Results There was no significant difference in the patients'general data among the three groups of patients (P ＞ 0.05).The incidences of postoperative complication in the seed group,the RF group and the control group were 55.3％,38.5％ and 20.7％,respectively.There was significant differences between the incidences of postoperative complications between the seed group and the control group (P ＜ 0.05).There was no perioperative death.The postoperative follow-up rate was 91.6％.Pain in the seed group and the RF group significantly improved,while it was not significantly improved in the control group.There were significant differences in the postoperative pain scores (P ＜0.05).The 6 months,1-year and 2-year overall survival rates were 61.3％,25.9％,8.6％ respectively.The median survival was 8 months.In the seed group,the 6 months,1-year and 2-year survival rates were 75.2％,37.8％,18.9％ respectively.The median survival was 9 months.In the RF group,the 6 months,1-year and 2-year survival rates were 60.4％,25％,6.3％ respectively.The median survival was 8 months.In the control group,the 6 months,1-year and 2-year survival rates were 53.4％,15.3％,3.8％ respectively.The median survival was 6.5 months.On log-rank test,there was no significant difference in survival rates among the three groups (P =0.145).Conclusions Patients with advanced pancreatic carcinoma had poor prognosis.I125 radioactive particles implantation and radiofrequency ablation were useful to improve patients'quality of life and prolonged their survival.

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 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.

Objective To investigate the efficacy and the indication and the management of perioperative complications in treatment of infra- kidney abdominal aortic aneurysm (AAA) by using endovascular graft exclusion (EVGE). Methods From April 2006 to September 2008, 24 patients with infra- kidney abdominal aortic aneurysms were diagnosed by contrast-enhanced CT or MRI scan. Vascular access was obtained through the bilateral femoral artery after arteriotomy and stent-graft was deployed into AAA of below the renal artery to occlude the left over cavity of AAA. The stent- graft was extended and anchored to the both side wall of AAA, the blood flow enter into the arteria iliaca communis through the sten't.Results Stent-graft deployment was successfully performed in all the patients. Immediate aortography after the procedure showed no leakage in 20 patients and the type Ⅰ minor leakage in 4 patients. No stent movement or organ and both lower extremities ischemia was found at the early post operative stage in all the patients. Six months after the operation, in all the 24 patients, contrast-enhanced CT scan showed the disappearance of the aneurysm and thrombosis at the level of the stent. Conclusions EVGE is simple,minimally invasive,less complication and quick recovery after operation. Thus it becomes first choice for the treatment of AAA for the elder patients.

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 explore the prognostic value of chemoradiotherapy based on the depth of invasion (DOI) in patients with oral squamous cell carcinoma. Methods : Patients with oral squamous cell carcinoma who received surgical treatment in a hospital from 2008 to 2016 were enrolled. The chi-square test was used to compare the effects of DOI on postoperative cervical lymph node metastasis and local recurrence. The effects of chemoradiotherapy on postoperative cervical lymph node metastasis, local recurrence, and survival were analyzed based on the DOI. Results: A total of 111 patients with oral squamous cell carcinoma were included in this study. The postoperative local recurrence rate (P<0.05) and cervical lymph node metastasis rate (P<0.05) of patients with 5 mm < DOI ≤ 10 mm and DOI > 10 mm were significantly higher than those with DOI ≤ 5 mm. The time of postoperative recurrence was concentrated within two years after the operation. The greater the DOI was, the shorter the time to postoperative recurrence (P<0.05). The addition of postoperative chemoradiotherapy did not significantly improve the postoperative local recurrence rate, cervical lymph node metastasis or survival rate of patients with different DOIs (P > 0.05). Conclusion DOI has important predictive value for postoperative recurrence, cervical lymph node metastasis and survival rate. However, DOI cannot be used as an independent index to guide whether chemoradiotherapy is needed after oral cancer surgery.
