ObjectiveTo analyse the outcomes of patients with Child-Pugh A class cirrhosis and a single hepatocellular carcinoma (HCC) up to 5 cm in diameter who underwent liver transplantation versus resection. MethodsDuring 2007 to 2011, 263 Child-Pugh A class cirrhotic patients with a single HCC up to 5 cm in diameter either underwent liver resection (n=227) or received liver transplantation (n=36) in our centre. Patients and tumour characteristics and outcomes were analysed. ResultsThe 1-, 3-, and 5-year recurrence-free survival rates of patients who received liver transplantation and liver resection were 91.7%, 85.3%, 81.0% and 80.6%, 59.8%, 50.8%, respectively (P=0.003). The 1-, 3-, and 5-year overall survival rates of patients who underwent liver transplantation were 100%, 87.5%, and 83.1% versus 96.9%, 83.8%, and 76.1% for patients received liver resection (P=0.391). The 1-, 3-, and 5-year recurrence-free survival rates for patients with a diameter of HCC < 3 cm underwent liver transplantation were 92.3%, 92.3%, and 92.3% versus 80.2%, 62.5%, and 50.5% for live resection group (P=0.019). The 1-, 3-, and 5-year overall survival rates for patients with a diameter of HCC < 3 cm underwent liver transplantation and liver resection were 100%, 91.7%, 91.7% and 97.7%, 87.5%, 79.5%, respectively (P=0.470). ConclusionsAlthough more recurrences are observed in Child A class cirrhotic patients with a single HCC up to 5 cm in diameter after liver resection, but overall survival rates for patients with a single HCC up to 5 cm in diameter are similar after liver resection and transplantation.
ObjectiveTo investigate the role of 3D visualization technology in the laparoscopic precise hepatectomy. MethodsTo retrieve the literatures about the application of 3D visualization technology in laparoscopic precise hepatectomy, and summarize and analyzed them. ResultsThe application of 3D visualization in laparoscopic precise hepatectomy could effectively reduce the operative time, blood loss, blood transfusion rate, and total complication rate. The application of 3D visualization in preoperative evaluation of the resection surface and residual liver volume had been relatively mature. Although many organizations try to use 3D visualization in laparoscopic hepatectomy, such as laser registration and real-time intraoperative navigation, it had not been widely used in clinic because of technical limitations. ConclusionsExisting research results show that, the application of 3D visualization technology in laparoscopic precise hepatectomy can improve the resectability of lesions, increase perioperative safety, but intraoperative navigation is still need to be further developed before it is expected to be widely used in clinical practice. Existing evidence of increased benefit from laparoscopic precise hepatectomy with 3D reconstruction remains limited, and more rigorous randomized controlled trials of large cases are needed to confirm this.
ObjectiveTo investigate the clinical characteristics of primary mass of the hepatoduodenal ligament (HDL) and present some thoughts in the diagnosis and treatment of this disease. MethodsSixteen consecutive patients diagnosed as having a primary mass of the HDL in the West China Hospital of Sichuan University from September 2004 to May 2013 were retrospectively investigated. ResultsThe symptoms and blood testing both lacked specificity. In this group, fourteen patients were examined by ultrasound and fifteen by contrast-enhanced computed tomography, with 3/14 (21.43%) and 5/15(33.33%) respectively defining the location of the lesions and characteristic of benign/malignant. When combining the ultrasound and contrast-enhanced computed tomography, six of twelve(50.00%) defined the location and characteristic of benign/malignant. When combined with contrast-enhanced magnetic resonance, ten of sixteen (62.5%) defined the location and characteristic of benign/malignant. All cases underwent abdominal exploration, 11 cases (68.8%) were porformed mass resected, 2 cases(12.5%) were porformed the simple HDL mass biopsy combined with biliary drainage with T tube, 1 case(6.2%) was porformed drainage for abscess of HDL, and 2 cases(12.5%) were porformed simple frozen biopsy. All cases recovered and discharged. ConclusionsThe diagnosis of a primary mass of the HDL is difficult. The united usage of multiple imageological examinations can increase the accuracy rate of the noninvasive preoperative diagnosis. Surgery and other active treatment can produce good prognosis.
ObjectiveTo evaluate the prognostic value of the easy albumin-bilirubin (EZ-ALBI) score for postoperative complications and long-term prognosis of hepatocellular carcinoma (HCC) patients. MethodsThe data on consecutive 1 822 HCC patients who underwent hepatectomy were obtained and retrospectively analyzed from five medical centers, including West China Hospital, Sichuan Provincial People’s Hospital, The First People’s Hospital of Neijiang City, The Second People’s Hospital of Yibin City, and People’s Hospital of Leshan City. Non-conditional logistic and Cox proportional hazards regression were used to evaluate the aspect on the postoperative complications and long-term prognosis. ResultsThe patients in EZ-ALBI grade 2 had higher incidences of severe complication (Clavein-Dindo classification>2, P=0.001), post-hepatectomy liver failure (P=0.040), length of stay>10 d (P<0.001), perioperative transfusion (P<0.001), and 90 d mortality (P<0.001). The 1-, 3- and 5-year cumulative survival rates in EZ-ALBI grade 1 group were 85.5%, 67.0%, and 58.7% while in EZ-ALBI grade 2 group were 72.7%, 51.1%, and 39.8%. Multivariate Cox proportional hazards regression manifested that patients in EZ-ALBI grade 2 had a significantly worse overall survival [HR=1.24, 95%CI (1.04, 1.48), P=0.015]. ConclusionThe EZ-ALBI score is an easy and feasible classifying method to predict postoperative complications and survival of HCC.
Objective To study the earthquake emergency response capability and post-earthquake psychological state of students after the Wenchuan earthquake. And also, to investigate the level of earthquake-related knowledge so as to provide basic information for enhancing the emergency response capabilities among college students. Methods We selected 1% Sichuan University students by convenience sample method and conducted the survey in person with a self-designed questionnaire. Results were analyzed with Epidata 3.0 and SPSS13.0 software. Results We distributed 527 questionnaires and 517 (97.27%) valid questionnaires were retrieved. Most college students had a good grasp of earthquake knowledge: 65.4% to 97.7% of the responders gave the correct answers, but only 12.77% said they had ever received earthquake survival training. 15.2% suffered from fear after the earthquake, 59.4% became uneasy, and 25.4% remained calm. Gender, grade, or major were not the factors influencing the psychological state of college students after the earthquake (P= 0.246, 0.216, and 0.406, respectively). Also, earthquake survival training did not influence the psychological state of college students after the earthquake (P=0.090). Psychological intervention after the earthquake was identified as an important factor that affected the psychological state of students (P=0.002). Conclusion College students have a good grasp of the basic knowledge regarding earthquake, but relevant survival training is far from sufficient. Universities should strengthen earthquake survival training, enhance the post-earthquake emergency response capacity of students, and carry out post-disaster psychological intervention directly following an earthquake. There is no significant difference in the mental status among students of different genders, grades, or professional backgrounds.
