ABSTRACT
ObjectiveTo study the role of hepatic arteriography before precise hepatectomy in primary liver cancer,Methods207 patients with primary liver cancers resected from 2005 to 2010 at Air Force General Hospital of Chinese PLA were studied retrospectively.There were 81 patients who received routine hepatectomy and 126 who received precise hepatectomy with hepatic arteriography before surgery.ResultsAnalysis showed that precise hepatectomy was superior to routine hepatectomy for lesions less than 1.0 cm (81.48％ vs 18.18％),with less operative time (168.20±35.81 min vs 221.75±30.33 min),volume of resection,blood loss (168.20±35.81 min vs 221.75±30.33 min),transfusion rate (256.13±185.24 ml vs 436.97±590.12 ml),and hospital stay (20.53± 12.41 d vs 25.72±17.27 d),(all P＜0.05).Hepatic arteriography did not affect liver function before precise hepatectomy.ConclusionsHepatic arteriography was significantly better in showing blood vessels of the primary liver cancer,and in detecting liver metastases or satellite lesions of less than 1.0 cm before surgery.
ABSTRACT
Objective To compare superiorities of liver malignant tumors underwent regular and irregular hepatectomies through approaching perioperative factors.Methods 1019 consecutive hepatectomies of liver malignant tumor from 1986 to 2009 at Air Force General Hospital and General Hospital of Chinese PLA were investigated retrospectively according to their medical documentation.Results Multivariate analysis showed that liver malignant tumors on which regular hepatectomy and irregular hepatectomy were performed,there was no significant difference in the blood loss,complications,mortality related to operation,hospital stay,and so on.But the operating time of regular hepatectomy was obvious more than that of irregular hepatectomy (P＜ 0.001,OR=1.004).Conclusions Although for liver malignant tumor,regular hepatectomy seems to be superior to irregular hepatectomy based on oncological theory,in clinical practice,there were no significant difference between the perioperative risk of regular hepatectomy and that of irregular hepatectomy.
ABSTRACT
Objective To investigate the construction and implementation of the concept of precise sequential therapy for primary liver cancer.Methods The clinical data of 207 patients with resectable liver cancer who were admitted to the Air Force General Hospital from May 2005 to June 2010 were retrospectively analyzed.Of all the patients,81 received conventional therapy (conventional therapy group),and the other 126 patients received precise sequential therapy (precise sequential therapy group).The conditions of the patients in perioperative phase,during postoperative sequential treatment and the period of follow-up between the 2 groups were compared.All data were analyzed by using the covariance analysis,analysis of variance,chi-square test or rank sum test.Results The detection rates of lesions with a diameter less than 1 cm,operation time,liver resection volume,intraoperative blood loss,rate of perioperative blood transfusion,duration of postoperative hospital stay,incidences of postoperative complications were 81％ (22/27),( 186 ± 36) minutes,(75 ± 29) ml,( 189 ± 60) ml,24％(30/126),(21 ± 12)days and 13％ (17/126) in the precise sequential therapy group,and 18％ (2/11),(222 ± 30)minutes,(133 ±88)ml,(327 ±46)ml,51％ (41/81),(26 ± 17)days and 20％ (16/81) in the conventional therapy group,respectively,with significant differences between the 2 groups (F =10.876,7.390,46.996,31.025,14.556,6.315,4.017,P ＜ 0.05).No significant difference was observed on the levels of alanine transaminase,albumin and the Child-Pugh score before and after the intervention in the precise sequential therapy group,but significant differences were observed in the conventional therapy group.The 1-,2-,3-year tumor recurrence rates and the 1-,2-,3-year survival rates were 17％ (21/126),22％ (17/76),26％ (8/31) and 87％ (110/126),87％ (66/76),84％ (26/31) in the precise sequential therapy group,and 31％ (25/81),38％ (27/71),48％(31/65 ) and 77％ (62/81),75％ (53/71 ) and 60％ (39/65) in the conventional therapy group,respectively.There were significant differences in the prognosis of the patients in the 2 groups ( x2 =4.958,4.292,4.168,4.062,3.640,5.470,P ＜ 0.05 ).Conclusion Through accurate assessment of the patients' condition before surgery,precise hepatectomy and precise postoperative intervention,the goal of effective control of tumor recurrence,maximum protection of the liver function and improvement of the survival rate can be achieved.
