【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.
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 explore the clinicopathological characteristics of combined hepatocellular and cholangiocarcinoma (cHCC-CC), and the prognostic factors associated with survival. MethodesThe clinical features of 31 patients with cHCC-CC from 1995 to 2010 in West China Hospital of Sichuan University underwent liver resection were analyzed retrospectively. The prognostic factors were analyzed by using univariate and multivariate analysis. ResultsOf these 31 patients, 25 men and 6 women, with a median age of 58 years, underwent liver resection for cHCC-CC. Twentythree cases (74.2%) showed positive of hepatitis B surface antigen (HBsAg), 13 cases (41.9%) had elevated AFP≥20μg/L, 18 cases (58.1%) with liver cirrhosis, 8 cases (25.8%) showed presence of lymph node metastases. The 1-, 3-, and 5-year overall survival rates of these patients were 61.3%, 32.3%, and 12.9%, respectively. Univariate analysis showed that invasion of portal vein, microscopic tumor thrombi, positive resection margins, and lymph node involvement were significant prognostic factors. Multiple analysis revealed the positive resection margins and lymph node involvement were independent prognostic factors for overall survival. ConclusionsThe prognosis of patients with cHCC-CC is poor. R0 resection is the only available treatment in curing these patients.
Objective To approach the clinical effect，feasibility， and advantages and disadvantages of laparoscopic liver resection for liver tumor. Methods The clinical data of 32 patients with liver tumor underwent laparoscopic liver resection from January 2009 to August 2011 in this hospital were analyzed retrospectively. Results The laparoscopic liver resection of 32 patients with liver tumor were performed successfully，including 23 cases of primary liver cancer，5 cases of metastatic liver，3 cases of liver hemangioma，1 case of focal liver nodular hyperplasia. Laparoscopic liver resection included left lateral lobectomy （Ⅱ＋Ⅲ segments） in 17 cases，left internal lobectomy （Ⅳ segment） in 2 cases （left lateral lobe was already removed），left hemihepatectomy （Ⅱ＋Ⅲ＋Ⅳ segments） in 8 cases，Ⅴsegmentectomy in 1 case，and Ⅵ segmentectomy in 1 case，and Ⅲ，Ⅳ，and Ⅴ segments hemihepatectomy in 3 cases. The average operation time of hepatectomy was 75-285 min with an average 215 min. Intraoperative bleeding was 115-760 ml with an average 365 ml. No complications such as bile leakage，hemorrhage，air embolism, and so on happened. The time of gastrointestinal function recovery was 1-3 d. The hospital stay was 5-11 d with an average 6 d. Thirty-one cases were followed-up，the follow-up time was 6-32 months with an average 18 months，except one case was died of tumor recurrence and metastasis in one year after operation，the rest were alive，no tumor recurrence and metastasis happened. Conclusions Laparoscopic liver resection for liver tumor has a small wound，less suffering，quick recovery，which is safe and feasible. The clinical effect is good．
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. ResultsSeventy-seven patients were underwent laparoscopic liver resection successfully,1 patient was conversed to open procedure.Operation method:laparoscopic anatomical liver resections were performed in 35 patients including 23 patients with left lateral segmentectomy,4 patients with left hemihepatectomy,3 patients with right hemihepatectomy,1 patient with Ⅲ segmentectomy,1 patient with Ⅵ segmentectomy,2 patients with Ⅵ and Ⅶ segmentectomy,1 patient with left lateral segmentectomy combined with Ⅵ and Ⅶ segmentectomy.Laparoscopic non-anatomical liver resection were performed in 43 patients.The operation time was (163.6 ±62.3) min,the intraoperative blood loss was (273.6±282.4) mL.No operative death occurred.One patient with postoperative functional bowel obstruction and 3 patients with pleural effusion had been recorded.All the patients recovered well.The postoperative hospital stay was (7.2±2.5) d.The results of postoperative pathology confirmed that all the tumors were hepatic cavernous hemangiomas. ConclusionsLaparoscopic liver resection for hepatic cavernous hemangioma is a safe and feasible method with small trauma,rapid recovery,cosmetic incision.Key of this technology is to strictly select surgical indications,to transect liver parenchyma along right plane,effective control of hepatic blood inflow,and properly management of cutting surface of liver.
ObjectiveTo examine long-term survival, morbidity, and mortality following hepatic resection for gastric cancer hepatic metastases and to identify prognostic factors that affect survival. MethodsA systematic literature search of EMbase, PubMed, Web of Science, The Cochrane Library (Issue 2, 2015), CBM, WanFang Data, and CNKI was undertaken for studies that evaluated the role of hepatic resection for gastric cancer hepatic metastases. Two reviewers independently screened studies based on inclusion and exclusion criteria, extracted data, and evaluated risk of bias of included studies. RevMan 5.3 software was used for meta-analysis. ResultsThirty-nine studies were included, of which, eight studies were included in meta-analysis. The median sample size was 21 (range 10 to 64). Procedures were associated with a median 30-day morbidity of 24% (0% to 47%) and mortality of 0% (0% to 30%). The median 1-year, 3-year, and 5-year survival rates were 68%, 31%, and 27%, respectively. Meta-analysis result of 8 cohort studies showed hepatic resection of hepatic metastases was associated with a significantly improved overall survival at 1-year and 2-year follow-up (RR=0.47, 95%CI 0.3 to 0.58, P < 0.000 01; RR=0.70, 95%CI 0.63 to 0.79, P < 0.000 01). ConclusionsPatients with hepatic metastasis from gastric cancer may benefit from hepatic resection. More trials are needed to confirm this finding because of the limited included studies and their low quality.
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.
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 identify the risk factors of postoperative recurrence and survival for patients with hepatocellular carcinoma within Milan criteria following liver resection. MethodsData of 267 patients with hepatocellular carcinoma within Milan criteria who received liver resection between 2007 and 2013 in our hospital were retrospectively analyzed. ResultsAmong the 267 patients, 123 patients suffered from recurrence and 51 patients died. The mean time to recurrence were (16.9±14.5) months (2.7-75.1 months), whereas the mean time to death were (27.5±16.4) months (6.1-75.4 months). The recurrence-free survival rates in 1-, 3-, and 5-year after operation was 76.8%, 56.3%, and 47.6%, respectively; whereas the overall survival rates in 1-, 3-, and 5-year after operation was 96.6%, 82.5%, and 74.5%, respectively. Multivariate analyses suggested the tumor differentiation, microvascular invasion, and multiple tumors were independent risk factors for postoperative recurrence; whereas the tumor differentiation, positive preoperative HBV-DNA load, and preoperative neutrophil-to-lymphocyte ratio adversely influenced the postoperative survival. ConclusionsFor patients with hepatocellular carcinoma within Milan criteria after liver resection, the tumor differentiation, microvascular invasion, and multiple tumors contribute to postoperative recurrence; whereas the tumor differentiation, positive preoperative HBV-DNA load, and preoperative neutrophil-to-lymphocyte ratio adversely influence the postoperative survival.
