Objective To describe the hemodynamic changes during piggyback liver transplantation (PBLT), and to analyze the hemodynamic correlation with various degrees of cirrhosis according to Childpugh classification. Methods Between March 1999 and June 2004, 180 patients underwent PBLT procedure in our institution, and 95 cases were selected and divided according to Child classification. The intraoperative hemodynamics of different time points were retrospectively analyzed, including mean artery pressure (MAP), heart rate (HR), central vein pressure (CVP) and mean pulmonary artery pressure (MPAP). Results Hemodynamic changes were minimal before and during anhepatic phase in all the patients. At reperfusion, a hemodynamic disturbance occurred featured by decrease of MAP and increase of MPAP. Comparison between different Child class showed that in the Child C group, MAP were lower and HR were higher before new liver phase, while CVP and MPAP were higher during new liver phase. Conclusion Hemodynamic changes were minimal before and during anhepatic phase for PBLT, while they were more severe during reperfusion, and they also correlates with the different Child class before transplantation. The more severe of the cirrhosis before transplantation according to Child classification, the greater hemodynamic changes during the operation.

OBJECTIVETo prevent and manage biliary complications after orthotopic liver transplantation (OLT).
METHODSNinety-five patients of OLT performed at our institute from February, 1999 to December 2002 were retrospectively analysed. Recipient operation was performed using standard method combined with veno-venous bypass in 12 patients and piggyback method in 78 patients and living-related liver transplantation in 5 patients. Biliary reconstruction was performed by end-to-end choledochocholedochostomy (C-C) over a T-tube in 55 patients and without a T-tube in 36 patients while the remaining 4 patients underwent Roux-en-Y choledochojejunostomy (CRY). C-C and CRY were performed by the interrupted or continuous suture with 5 - 0 or 6 - 0 Vicryl or PDS. Routine examination of liver function, Doppler ultrasonography and cholangiography were performed during the follow-up period.
RESULTSBiliary complications occurred in 7 patients (7.3%). Two patients with bile leakage at the anastomotic site developed biliary peritonitis on the seventh and tenth postoperative day and needed reoperation. One patient developed anastomotic biliary stricture one month after the operation and was cured by endoscopic stenting. Two patients developed bile leakage after T-tube removal. One of the two patients was treated conservatively and the other underwent a exploratory laparotomy to ligate the T-tube tract and drain the peritoneal cavity. One patient died of biliary vast syndrome five months after OLT and one patient died of biliary tract necrosis secondary to hepatic artery thrombosis on the tenth postoperative day. One - 42-month (mean 11.4 months) follow-up revealed no biliary stricture in 74 patients. No biliary stone and biliary sludge were detected by Doppler ultrasound and/or cholangiography. Serological examinations proved that liver grafts functioned well in these patients.
CONCLUSIONSTo prevent biliary complications, it is crucial to protect biliary mucosa and arterial blood supply of the common bile duct while harvesting the graft and to obtain perfect mucosa-to-mucosa apposition of no-tension end-to-end anastomosis of the bile duct. Endoscopic dilation and stenting are effective for post-OLT extrahepatic biliary stricture.

OBJECTIVETo evaluate the prognostic value of surgical operation-related factors in patients with hepatocellular carcinoma (HCC).
METHODSThe clinical data of 234 patients after hepatic resection (214 men and 20 women) were retrospectively studied. Univariate and multivariate COX regression analyses were performed for surgical operation-related prognostic factors including age, gender, intraoperative blood loss, iatrogenic tumour rupture, transfusion, operation duration, hepatectomy extent, Pringle manoeuvre, with or without devarscularization, and complications (e.g. postoperative ascites, biliary leakage, incision infection, and pleural effusion). Kaplan-Meier and log-rank tests were used to compare survival rates. Kendall's tau bivariate analyses were used to examine the correlations of these surgical operation-related factors.
RESULTSUnivariate COX regression analysis revealed that iatrogenic blood loss (chi2 = 19.721, P < 0.001), transfusion (chi2 = 7.769, P = 0.005), tumour rupture (chi2 = 6.401, P = 0.011), operation duration (chi2 = 4.793, P = 0.029), and postoperative ascites (chi2 = 4.452, P = 0.035) were statistically significant predictors in patients with HCC after hepatic resection. Multivariate COX regression analysis revealed that pathological factors, such as blood loss (RR: 2.138, 95% CI: 1.556-2.939), tumour rupture (RR: 2.260, 95% CI: 1.182-4.321), and postoperative ascites (RR: 1.648, 95% CI: 1.088-2.469), independently influenced the HCC prognosis. Blood loss correlated with transfusion (Kendall's tau = 0.416, P < 0.001). There was no correlation between hepatectomy extent and blood loss (Kendall's tau = 0.057, P = 0.383), while transfusion closely correlated with the hepatectomy extent (Kendall's tau = 0.185, P = 0.004). The postoperative ascites closely correlated with Child classification (Kendall's tau = 0.151, P = 0.024).
CONCLUSIONSThe long-term survival of patients with HCC after hepatectomy may be improved by avoiding blood loss and iatrogenic tumour rupture. The indications of blood transfusion may not be strictly obeyed in some severe cases. Child class B and C cirrhotic patients may experience postoperative ascites and a worse prognosis, and therefore may be candidates for liver transplantation.

OBJECTIVETo explore the application of endoscopic transnasal prelacrimal recess-maxillary sinus approach in surgery for lesions in the pterygopalatine fossa.
METHODSFive patients with tumors of pterygopalatine fossa were treated by endoscopic transnasal prelacrimal recess-maxillary sinus surgery between May 2008 and May 2011. The lesions treated included 4 schwannoma. and 1 neurofibroma. The operation began with endoscopic transnasal lateral nasal wall approach to maxillary sinus. Then after opening posterior wall of maxillary sinus, the pterygopalatine fossa was entered and the tumor was removed. The operation was performed under hypotension anaesthesia.
RESULTSThe tumors were removed totally in all 5 patients. No complication was found. After the surgery, all patients fully recovered and were discharged from the hospital in 5 to 12 days. No recurrence and death occurred during the follow up periods ranging from 5 to 28 months.
CONCLUSIONSEndoscopic transnasal prelacrimal recess-maxillary sinus approach is safe and effective management for benign tumors in the pterygopalatine fossa. This approach reserved nasolacrimal duct and turbinate, maintained the structure and function of the nose, with decreased morbidity and shorter recovery periods.

OBJECTIVETo evaluate the effects of primary duct closure and T-tube drainage in laparoscopy choledochotomy to treat the common bile duct stones.
METHODSThe enrollment of the patients was in accordance with 6 criteria. 55 patients with cholecystolithiasis and secondary common bile duct stones from January 2000 to February 2003 were treated with laparoscopic choledochotomy. The patients were randomly divided into two groups: primary duct closure group and T-tube drainage group. Their all data were recorded and studied prospectively,and patients were followed up after discharge.
RESULTSThere were 27 patients and 28 patients in primary duct closure group and T-tube drainage group respectively. The operation time and the results of following up between the two groups had no significant difference. Compared with T-tube drainage group, primary duct closure group had less the total quantity of postoperative transfusion and hospital costs, shorter postoperative hospital stay. The incidence of postoperative complications in primary duct closure group was 11.1% (3/27), and all of them were biliary complications. The incidence of postoperative complications in T-tube drainage group was 28.6% (8/28), and seven of them were biliary complications. The incidence of severe complications that needed reoperations was 10.7% (93/28), and all of them were caused by T-tubes. There was no mortality in two groups.
CONCLUSIONSThe primary duct closure in laparoscopic choledochotomy can avoid the deficiency of T-tube drainage, and it is feasible and safe and lower complications in treating the common bile duct stones, so we advocate it in appropriate cases.

OBJECTIVETo evaluate the role of orthotopic liver transplantation (OLT) in treating hepatocellular carcinoma (HCC).
METHODSData of 92 consecutive orthotopic liver transplantations (OLTs) performed during January 1999 and February 2005 at our institution were analyzed.
RESULTSOf the 92 recipients, 8 HCC patients were stage I, 13 were stage II, 12 stage III and 59 stage IV (UICC TNM staging system). Overall 1-, 2-, 3-, 5-year patient survival rates were 65.3%, 27.0%, 20.0%, and 6.9%, respectively. When OLT indications were considered, best recipients survival was obtained in stage I patients (100.0%, 100.0%, 66.7%, and 50.0% at 1, 2, 3, and 5 years, respectively) and stage II patients (85.7%, 66.7%, and 66.7% at 1, 2 and 3 years, respectively). Whereas, 1, 2, 3 and 5-year recipients survival rates were 50.0%, 0, 0, 0 in stage III patients, and 58.1%, 20.0%, 13.0% and 5.0% in stage IV patients.
CONCLUSIONSThe prognosis of different stages of HCC patients who underwent OLT was significantly different. The OLT recipients with HCC should be strictly selected. Long-term recipient survival could be obtained in stage I and stage II patients.

OBJECTIVETo assess the relationship of the variation of exon 20 of leptin receptor (LEPR) gene to the lipid metabolism and fat distribution of the children with obesity.
METHODSPolymerase chain reaction-restriction fragment length polymorphism(RFLP) and polyacrylamide gel electrophoresis were used to analyze the variation of exon 20 of the LEPR gene of the obesity group(72 obesity children) and the control group(60 healthy children). At the same time, all childrens' serum triglyceride(TG),total cholesterol(TC),high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C), height and weight were measured, and their body mass index(BMI) and fat percent(%fat) were calculated.
RESULTSThree genotypes of exon 20 of LEPR gene were detected in this study. Compared with the control, the frequency of gene variation at 3057 nucleotide G-->A transversion was higher(P<0.05). The concentration of serum TG and the BMI and %fat of the A/A genotype obesity children were higher than those of the G/G genotype ones(P<0.01) but the level of serum HDL of the A/A children were lower than that of the G/G children (P<0.01). As to the G/A genotype children, only their serum TG level was higher than that of the G/G genotype ones(P<0.05).
CONCLUSIONThe above findings indicated there were polymorphisms in the children with obesity, and those polymorphisms might remarkably affect their lipid metabolism and fat distribution.

OBJECTIVETo study the security and curative effect of radiofrequency ablation (RFA) for hypersplenism due to portal hypertension in the near future.
METHODS12 patients of the disease were treated with RFA. The blood count showed that WBC is (2.0 +/- 0.7) x 10(9)/L, PLT (25 +/- 10) x 10(9)/L, RBC (3.08 +/- 0.56) x 10(9)/L. In manners of systemic anaesthesia, through skin or in the operation or under the celioscopes the RFA needles are inserted the upper and middle parts of spleen in the instructing of US. Average time of RFA is (36.4 +/- 5.4) s.
RESULTSAfter the RFA, 1 case develop hematoma under the envelope of liver, and 1 case developed skin burn; 6 patients appeared middle or little fluid in the left thorax, 2 of them were drawn through puncture. The volume of spleen and damaged part of spleen from RFA were determined by enhanced CT in the days of 10 after RFA, the percentage of damaged part of spleen from RFA is 49.1% (23.3% - 88.9%). In the days of 14 after RFA, RBC is (5.5 +/- 0.9) x 10(9)/L, PLT is (124 +/- 21.36) x 10(9)/L; In the days of 33 after RFA, RBC is (5.4 +/- 1.1) x 10(9)/L, PLT is (205 +/- 34) x 10(9)/L. The levels of WBC and PLT in the blood after RFA are significantly higher than those of levels of WBC and PLT before RFA (P < 0.01).
CONCLUSIONSRadiofrequency ablation for Hypersplenism due to portal hypertension of hepatitis hepatocirrhosis is safety and credibility and has excellent curative effect in the near future.
