ObjectiveTo follow-up pain after discharged in patients with liver resection and provide a reference to carry out the continued pain treatment outside the hospital. MethodsPost-discharged pain follow-up in patients with liver resection in our department from December 1, 2014 to April 30, 2015 were conducted, and the pain incidence, characteristics and level on 14 days, 1 month, 2 months, and 3 months after operation were understanded. Results①The pain score of patients on 14 days after operation was 0-3 points, which was mild pain. In 2 months after operation, 24 patients still had pain, the incidence was 20.69% (24/116). In 3 months after operation, the pain incidence was 18.97% (22/116).②There was no significant difference in the pain incidence between men and women in 2 months after operation (P > 0.05). In 3 months after operation, the pain incidence of male and female patients was 13.04% (9/69) and 27.66% (13/47), respectively, the pain incidence of female was significantly higher than men (P < 0.05).③The postoperative pain score and incidence in patients more than 60 years old were lower than that in patients less than 60 years old, but the score and the incidence of postoperative pain in patients with different ages were not statistically significant (P > 0.05).④In chronic pain patients, 81.82% (18/22) were visceral pain, 18.182% (4/22) were skin tingling or numbness. ConclusionWe should focus on the continued pain treatment outside the hospital in patients with hepatic resection, make efforts to alleviate pain, and improve the postoperative quality of life.
ObjectiveTo investigate the expression of IQ motif-containing GTPase activating protein 1 (IQGAP1) in hepatocellular carcinoma (HCC) tissues, and to analyze the relationship of IQGAP1 and patient's clinical characteristics and prognosis after liver resection. MethodsData of 79 patients who received liver resection between 2007 and 2009 in our hospital were collected. The expression of IQGAP1 was examined by immunohistochemical tests. The clinical characteristics and prognosis were compared. ResultsIQGAP1 was detected in 43 patients (54.4%). Patients with IQGAP1 expression had more poor differentiation and microvascular invasion. The cumulative recurrence-free rate and overall survival rate in 1-, 3-, and 5-year after operation of patients with IQGAP1 expression (cumulative recurrencefree rate:67.4%, 39.5%, and 23.3%; cumulative overall survival rate:97.7%, 71.5%, and 53.3%) were poor than patients without IQGAP1 expression (cumulative recurrence-free rate:100%, 94.4%, and 83.3%; cumulative overall survival rate:1007%, 97.2%, and 88.9%), P < 0.001. ConclusionsHCC patients with IQGAP1 expression had a poor prognosis after liver resection. IQGAP1 may be a prognostic indicator for hepatocellular carcinoma.
ObjectiveTo summarize the experiences of precise liver resection for giant complex hepatic neoplasm. MethodsFifty-two cases of giant complex hepatic neoplasms were resected using precise liver resection techniques from April 2008 to August 2009. Hepatic functional reserve and liver imaging were evaluated before operation. Appropriate surgical approach, halfhepatic blood flow occlusion, new technique of liver resection, and intraoperative ultrasonography were applied during operation. ResultsThe mean operative time, halfhepatic blood occlusion time, blood loss, recovery of alanine aminotransferase, and total bilirubin were 350 min (210－440 min), 43 min (8－57 min), 370 ml (250－1 150 ml), 10 d (7－14 d), and 4.5 d (3－10 d), respectively. Only 6 patients had mild bile leakage. No liver failure and other major complications emerged, and no death happened. ConclusionPrecise liver resection is a safe and effective approach for giant complex hepatic neoplasm.
ObjectiveTo investigate indications,technical points,and outcomes of laparoscopic liver resection in treatment for hepatic hemangioma. MethodThe clinical data of 78 patients with hepatic hemangioma underwent laparoscopic liver resection in our institute from January 2014 to December 2014 were analyzed retrospectively.

Objective?To approach feasibility, safety, and the application range of pure laparoscopic resection （PLR）, hand-assisted laparoscopic resection （HALR）, and robotic liver resection （RLR） in the minimally invasive liver resection （MILR）. Methods?The clinical data of 128 patients underwent MILR in the Surgical Department of the Shanghai Ruijin Hospital from September 2004 to January 2012 were analyzed retrospectively. According to the different methods, the patients were divided into PLR group, HALR group, and RLR group. The intraoperative findings and postoperative recovery of patients in three groups were compared.?Results?There were 82 cases in PLR group, 3 cases of which were transferred to open surgery；the mean operating time was （145.4±54.4） minutes （range：40-290 minutes）；the mean blood loss was （249.3±255.7） ml （range：30-1 500 ml）；abdominal infection was found in 3 cases and biliary fistula in 5 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （7.1±3.8） days （range：2-34 days）. There were 35 cases in HALR group, 3 cases of which were transferred to open surgery；the mean operating time was （182.7±59.2） minutes （range：60-300 minutes）；the mean blood loss was （754.3±785.2） ml （range：50-3 000 ml）；abdominal infection was found in 1 case, biliary fistula in 2 cases, and operative incision infection in 2 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （15.4±3.7） days （range：12-30 days）. There were 11 cases in RLR group, 2 cases of which were transferred to open surgery； the mean operating time was （129.5±33.5） minutes （range：120-200 minutes）； the mean blood loss was （424.5±657.5） ml （range：50-5 000 ml）； abdominal infection was found in 1 case and biliary fistula in 1 case after operation, but all recovered after conservative treatment； the mean length of hospital stay was （6.4±1.6） days （range：5-9 days）. The operating time （P=0.001） and length of hospital stay （P=0.000） of the RLR group were shortest and the blood loss （P=0.000） of the PLR group was least among three groups. Conclusions?Minimally invasive resection is a safe and feasible. Different surgical procedures should be chosen according to different cases. The robotic liver resection provides new development for treatment of liver tumor.
ObjectiveTo explore the value liver resection combined with intraoperative radiofrequency ablation during the same period in the treatment of multiple liver cancer. MethodsWe retrospectively analyzed the clinical data of 33 patients with multiple liver cancer treated between January 2005 and April 2013. All the patients were treated by liver resection combined with intraoperative radiofrequency ablation in the same period. There were 91 tumor foci in 33 patients, among which 39 tumor foci were surgically removed, and 52 tumor foci were radiofrequency ablated. Ultrasonography and enhanced CT/MRI were performed for the patients 1 year, 2 years and 3 years after surgery. ResultsNo bleeding or death occurred during the operation. It was observed that the transient liver function was damaged after surgery, but it quickly returned to A level after treatment. All the patients had no perioperative death or other serious complications. Tumor recurrence rate was 16.1% in the first year, 48.4% in the second year and 93.5% in the third year after surgery. ConclusionLiver resection combined with intraoperative radiofrequency ablation for multiple liver cancer in the same period is feasible and safe, without increasing the average length of hospital stay, operative mortality rate and postoperative tumor recurrence rate.
ObjectiveTo summary the progress and status of downstaging therapy in treating hepatocellular carcinoma. MethodsThe related literatures were reviewed and analyzed by searching PubMed and MEDLINE. ResultsAlthough the clinical prognosis of advanced hepatocellular carcinoma was poor, the liver resection or liver transplantation after downstaging therapy could significantly improve the prognosis of patients. However, differences were existed if different downstaging therapies and selections of standard were used. ConclusionTo improve the prognosis of patients with advanced hepatocellular carcinoma, the downstaging therapy should be ingeniously selected based on the situation of the patients.
ObjectiveTo observe the impact of antiviral therapy on prognosis in patients after curative resection for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). MethodsThe data of 50 patients who had undergone liver resection for HBV-related HCC in our department from August 2008 to June 2012 were retrospectively analyzed. The patients were divided into two groups:21 patients who had not antiviral therapy (untreated group) and 29 patients who received antiviral therapy using nucleotide analogues (antiviral therapy group). ResultsAfter radical resection of HCC, the disease-free survival rate of 1-year, 3-year, and 5-year were 72.4%, 58.6%, and 31.0% in antiviral therapy group and 61.9%, 38.1%, and 14.3% in untreated group, respectively. The overall survival rate of 1-year, 3-year, and 5-year were 86.2%, 68.9%, and 55.2% in antiviral therapy group and 71.4%, 47.6%, and 28.6% in untreated group, respectively. The cumulative disease-free survival rate and overall survival rate of antiviral therapy group were significantly higher than those in the untreated group (P < 0.05). Univariate analysis revealed that the number of tumor, antiviral therapy, and TNM staging were risk factor for tumor-free survival rate, The tumor size, the number of tumor, antiviral therapy, and TNM staging were risk factor for overall survival rate. Multivariate analysis revealed that the number of tumor and TNM staging were independent risk factor for tumor-free survival rate (OR:2.95, 95% CI:1.502-6.114, P < 0.05; OR:4.12, 95% CI:1.972-8.960, P < 0.05), the antiviral therapy and TNM staging were independent risk factor for overall survival rate (OR:3.86, 95% CI:1.745-7.028, P < 0.05; OR:5.17, 95% CI:2.356-11.479, P < 0.05). ConclusionUsing nucleotide analogs antiviral therapy may improve the prognosis after resection of patients with HBV-related HCC.
【Abstract】Objective To investigate whether liver resection for hepatocellular carcinoma (HCC) causes dissemination of liver tumor cells into blood circulation. Methods Fourteen patients with HCC, but without evidences of metastasis, were enrolled for the study. Blood samples of peripheral blood before skin incision and after abdominal wall suture, and of hepatic venous blood and portal venous blood after liver parenchyma dissection, were obtained. AFPmRNA was detected by reverse transcription polymerase chain reaction assays, the change of the level of its expression during operation was assessed by semi-quantitative analysis. Results The rate of its expression before and after operation in peripheral blood, and during operation in portal venous blood and in hepatic venous was 42.9%, 35.7%, 42.9% and 57.1% respectively. There were no differences between them. However, the level of its expression in hepatic venous blood was significantly higher than others (P＜0.05). Conclusion Liver resection for HCC induces releases of cells from the liver, probably including tumor cells, into blood circulation.
