  • Application of Hepatic Vascular Control in Laparoscopic Hepatectomy

    Objective To investigate the technique and feasibility of hepatic pedicle vascular control in laparoscopic hepatectomy. Methods From May 2005 to June 2011, 95 cases of hepatectomies were performed by laparoscopy in the Department of Minimally Invasive Surgery, The First Affiliated Hospital, Guangxi Medical University.The characteristics of these cases were analyzed. Results Left lateral segmentectomy were required in 21 patients, left hepatectomy in 13 patients, right hepatectomy in 4 patients, segmentectomy in 17 patients, tumor resection in 24 patients,hemangioma resection in 5 patients, and conversions to laparotomy in 11 patients. The intermittent Pringle maneuver were performed in 39 patients. The mean vascular clamping time in Pringle maneuver was (30.84±9.51) min. The selective vascular control of inflow were performed in 56 patients, the technique included intrahepatic Glisson approach in 14 patients and controlling hepatic artery and portal vein separately in 42 patients. Pre-parenchymal transection control of hepatic outflow were performed in 12 patients, included the left hepatic vein were controlled by suturing or separating in 11 patients and right hepatic vein was controlled by separating in 1 patient. Others were controlled intraparenchymally during transection. The mean operative time was (236.80±95.97) min,mean operative blood loss was( 551.55±497.41) ml, concentrate red blood cells transfusion volume was( 2.60±2.23) U, and plasma transfusion volume was (211.90±179.29) ml. The postoperative complications included bleeding in 4 patients, pleural effusion in 4 patients, pneumonia in 3 patients, ascites in 7 patients, and biliary fistula in 2 patients, and dead in 1 patient. The mean hospitalization time was( 12.47±4.18) days. At the deadline( February 2012), 72 cases with liver cancer were followup. The follow-up time ranged from 5 to 81 months and the mean time was( 24.14±16.62) months, where survival rate was 68.4%( 54/79) of 1-year and 21.5%( 17/79) of 3-year. Conclusions The application of hepatic pedicle vascular control in laparoscopic hepatectomy is feasible.

  • THE PREVENTION OF SUBPHRENIC INFECTION AFTRE HEPATECTOMY

    One hundred and five hepatic resection were performed from 1984 to 1994. Six of these patients complicated with subphrenic infection after hepatectomy, of whom two patients died of liver failure. Subphrenic dropsy occureeed in nine cases. Subphrenic infection is easy to occur in: right or extend lobectomy, massive blood loss at operation, and in postoperative bleeding which subjects to laparotomy for lemostasis. Seecure hemostasis, avoidence of hepatic tissue devitalization during operation and effective subphenic drainage aree essential to reduce the incidencee of subphrenic infection, and routine bacterial culture of subphrenic drainage fluid will help to select propre antibiotic.

  • Outcome Comparison of Right Hepatectomy among Living Liver Donation and Hepatic Patients with or Without Cirrhosis

    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.

  • Observation of hepatitis B reactivation within 1 month after partial hepatectomy

    Objective To clarify incidence and risk factors of hepatitis B reactivation during short term (one month) in hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) patients receiving partial hepatectomy. Methods From January 2015 to December 2015, 214 consecutive patients with HBV-related HCC who underwent partial hepatectomy were retrospectively enrolled in this study. The risk factors affecting incidence of hepatitis B reactivation were analyzed. Results Hepatitis B reactivation happened in 7.0% (15/214) of patients within 1 month after partial hepatectomy. By univariate analysis, the preoperative HBV-DNA negativity and hepatitis B e antigen (HBeAg) positivity were significantly correlated with the occurrence of hepatitis B reactivation (P=0.023 and P=0.001, respectively). By multivariate analysis, the preoperative HBV-DNA negativity 〔OR=9.21, 95% CI (2.40, 35.45), P=0.001〕 and HBeAg positivity 〔OR=20.51, 95% CI (5.41, 77.73), P<0.001〕 were the independent risk factors for hepatitis B reactivation. Conclusions Hepatitis B reactivation is common after partial hepatectomy for HBV-related HCC during short term, especially in patients whose preoperative HBV-DNA negativity and HBeAg positivity. A close monitoring of HBV-DNA during short term after partial hepatectomy is necessary, once hepatitis B is reactivated, antiviral therapy should be given.

  • Surgical Treatment of the Intrahepatic Lithiasis Combined with High Hepatic Duct Strictures

    Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepatic 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 eightythree 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 reoperated. 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.

  • Effect of “in situ first” ex vivo liver resection and autologous liver transplantation for end stage hepatic alveolar echinococcosis

    Objective To explore the effect of “in situ first” ex vivo liver resection and autologous liver transplantation (ELRA) for end stage hepatic alveolar echinococcosis (HAE). Methods The clinicopathologic data of 85 end stage HAE cases were initially scheduled underwent ELRA from June 2019 to May 2022 in the Sichuan Provincial People’s Hospital were collected retrospectively. The included cases were operated under “in situ first” ERLA principle. The analyzed data included the final surgical style, operative time, time of anhepatic phase and intraoperative blood transfusion volume for ELRA cases. Results All the included 85 cases underwent radical HAE lesions resection and without perioperative death occurred. According to the principle of “in situ first”, 57 cases underwent HAE lesions resection combined vascular reconstruction without ex vivo liver resection (in situ resection group); 1 case underwent auxiliary partial autologous liver transplantation, and 27 cases underwent ERLA procedures (ELRA group). In the in situ resection group, the operative time was 210–750 min, (380±134)min, and the intraoperative blood transfusion was 0–3 250 mL with a median of 0 mL. In the ELRA group, the operative time was 450–1 445 min, (852±203) min, and the intraoperative blood transfusion was 0–6 800 mL with a median of 1 960 mL. The operative time and the amount of blood transfusion in the ELRA group were longer or more than those in the in situ resection group. The time of anhepatic phase for the ELRA group was 60–480 min, (231±83) min. On the 5th day after operation, except that the total bilirubin and direct bilirubin in the ELRA group were higher than those in the in situ resection group, the other indexes of liver function were similar between the two groups. The postoperative stay in ICU and the total postoperative hospital stay in the ELRA group were longer than those in the in situ resection group. Conclusions The advantage of “in situ first” ERLA principle for end stage HAE patients include resecting the HAE lesions radically without ex vivo liver resection and alleviating the hepatic ischemia and reperfusion injury. For the inevasible ELRA cases, “in situ first” principle could shorten the anhepatic phase and reduce intraoperative blood loss, and turn some cases to auxiliary partial autologous liver transplantation, which will reduce the risk of postoperative hepatic failure.

  • Research Advancement of Hepatic Ischemic Preconditioning

    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 ischemiareperfusion 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.
