Objective To approach whether the postoperative recovery processes of the living donors and hepaticpatients after right hepatectomy is similar. Methods The clinical data of consecutive cases from 2009 to 2010 in our liver transplantation center was retrospectively analyzed， including 40 cases who donated the right lobe without the middlehepatic vein （living donor liver transpalntation-donor group， abbreviated as LDLT-D group） and 80 hepatic patients forright hepatectomy， in which 40 cases were hepatic patients without cirrhosis （liver disease-noncirrhosis group， abbreviatedas LD-NC group） and 40 cases were hepatic patients with cirrhosis （liver disease-with cirrhosis group， abbreviated asLD-WC group）. Preoperative liver function and general clinical data， intraoperative blood loss and transfusion， postoper-ative liver function， and complications were statistically analyzed in this study. Results The preoperative parameters of three groups were comparable. LDLT-D group experienced more intraoperative bleeding than LD-NC group 〔（765±411） mL vs. （584±242） mL， P=0.008〕， and was similar to LD-WC group 〔（666±224） mL， P=0.136〕. However， the average amount of blood transfusion products was similar among the 3 groups （P=0.108）. The levels of total bilirubin and INR of LDLT-D group were higher than LD-NC group and LD-WC group on the first and third day after operation （P＜0.05）. The levels of ALT and AST of LD-WC group were higher than LDLT-D group and LD-NC group （P＜0.05）. The overall postoperative surgical morbidity incidence of LDLT-D group， LD-NC group， and LD-WC group were 30.0%（12/40）， 27.5% （11/40）， and 37.5% （15/40） respectively， and were not statistically significant （P=0.606）. However， the ClavienⅢcomplication rate of LD-WC group was higher than LDLT-D group and LD-NC group 〔27.5% （11/40） vs. 7.5%（3/40） and 10.0% （4/40）， P=0.024〕. Conclusions Liver function of living donors is injured more seriously during the early postoperative period. The total complication rates after right hepatectomy are similar among the living liver donation and hepatic patients with or without cirrhosis. However， the serious complication rate of cirrhotic liver recipients is higher than living donors and patients without cirrhosis.
Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepatic duct strictures. MethodsTwo hundreds and sixteen cases of intrahepatic lithiasis and high hepatic duct strictures treated in this hospital from January 1993 to October 2002 were analysed retrospectively.ResultsOne hundred and eightythree cases underwent different selective operation by selected time; 33 cases complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were reoperated. The operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic repair with own patch and choledochojejunostomy.Two hundreds and six cases were cured,the curative rate was 95.4%; 8 cases improved (3.7%), and 2 cases died (0.9%).Conclusion The best effective surgical treatment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct strictures and to clear the intrahepatic lithiasis. For patients with normal extrahepatic bile duct and Oddi’s function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholangioscopy may play an important role in the treatment of intrahepatic tract lithiasis during operation.
Objective To study the effect of recombinant growth hormone (rhGH) on improvement of liver function and liver regeneration in animal and patients after hepatectomy. Methods The liver cirrhosis model of SD species mouse was set up, then the mouse were randomly divided into experiment group and control group, then 30%-40% liver of all the models were resected, rhGH was used by hypodermic injection (0.2-0.4ml/100g) in experimental group, and the equal dose of N.S. were given in control group every day. Then liver function, arterial blood ketone body ratio(AKBR), and the regenerated liver/body weight ratio (RL/W) were determined, histopathology of the cirrhosis with microscope and electron microscope and the mitotic index (MI) of liver cell on 7, 14 and 28th day after operation were observed. Clinically,39 hepatectomized patients were randomly divided into experiment group and control group, liver function, PA， Glu, RI and AKBR were measured preoperatively and on 1, 7,14th day after operation. Postoperative clinical course were also compared between the two groups. Results In the animal experiment group, as compared with the control group, AKBR was obviously higher (P＜0.01), seruim level of total protein and PA were increased faster (P＜0.05), and RL/W was higher. The mitotic index of liver cell was increased faster on 14th day, the numbers of regenerated liver cell with double nucleus and rough endoplasmic reticulum were higher in 14 and 28th day. In the clinical experiment group, as compared with the control group, serum total bilirubin, alanine aminotransferase and aspartate aminotransferase were lower on 7 and 14th postoperative day (P＜0.05). Serum albumin, PA, Glu, RI and AKBR were higher on 7, 14th postoperative day (P＜0.05). Conclusion Both experimental and clinical study show that the rhGH can promote liver regeneration and improve liver function after hepatectomy.
ObjectiveTo investigate the impact of elevated fasting blood glucose (FBG) level after open radical hepatectomy on the early recurrence of hepatocellular carcinoma (HCC).MethodsThe clinical data of 112 patients with HCC who underwent the open radical hepatecomy from January 2013 to December 2014 in the Affiliated Hospital of Qingdao University were retrospectively analyzed. After the radical resection of HCC, 86 patients with level of FBG 3.9–6.1 mmol/L and 26 patients with level of FBG≥6.1 mmol/L were design into a normal FBG group and an elevated FBG group, respectively. The recurrence rates of HCC were compared between the two groups at 1- and 2-year after the opreation.ResultsThere were no significant differences between the 2 groups in the gender, age, history of alcohol drinking, hepatitis B history, preoperative ALT, AST, AFP and Child-Pugh classification, scope of hepatectomy, intraoperative hemorrhage, hepatic blood flow occlusion, diameter of maximal tumor, histopathological differentiation, tumor number, cirrhosis, satellite lesion, postoperative adjuvant TACE treatment or not (P>0.05). The postoperative 1- and 2-year recurrence rates of HCC were 19.8% (17/86) and 33.7% (29/86) in the normal FBG group and 42.3% (11/26) and 61.5% (16/26) in the elevated FBG group, respectively, showing significant differences between the 2 groups (P<0.05). The results of multivariate analysis showed that the level of FBG≥6.1 mmol/L, low histopathological differentiation, and no postoperative TACE treatment were the independent risk factors affecting tumor-free survival rate after the open radical resection of HCC (P<0.05). ConclusionsElevated FBG level after open radical resection has a stimulative effect on early recurrence of HCC. As a result, monitoring and controlling of FBG level after operation is helpful in decreasing early recurrence rate of patients with HCC.
ObjectiveTo summarize recent researches on mechanism of the hepatic ischemic preconditioning (IPC) and its clinical applications on hepatectomy and liver transplantation. MethodsRelevant references about basic and clinical researches of hepatic IPC were collected and reviewed. ResultsRecent experimental researches indicated that IPC could relieve hepatic ischemiareperfusion injury (IRI) by remaining and improving energy metabolism of liver, regulating microcirculation disorder, decreasing the production of lipid peroxidation and oxyradical. It could also inhibit the activation of inflammatory cells and the release of cytokine, suppress cell apoptosis and induce the release of endogenous protective substance. Till now, most of the clinical researches had confirmed the protective function of hepatic IPC, but there were still some references with opposite opinions. ConclusionHepatic IPC could relieve liver IRI, but its clinical application value on hepatectomy and liver transplantation still need more researches to prove.
Objective To investigate the feasibility of elective laparoscopic hepatectomy in the treatment of ruptured hepatocellular carcinoma. Methods We tried to perform an elective laparoscopic hepatectomy for a middle-aged man who had a ruptured hepatocellular carcinoma without active hemorrhage. The data of this patient was summarized. Results The patient received the elective laparoscopic hepatectomy, and the liver lesions were completely removed. The operation was successful. Operative time was 300 min and intraoperative bleeding was 500 mL. Postoperative recovery of this patient was good and no complication occurred. The abdominal drainage tube was removed on 4 days after operation, and he discharged on 8 days after operation. The pathology confirmed that the hepatocellular carcinoma was moderately differentiated and ruptured. Conclusion Elective laparoscopic hepatectomy is safe and feasible in the treatment of ruptured hepatocellular carcinoma for specific patient, but this operation needs to be performed by experienced surgeons with laparoscopic skills.
