Preoperative Evaluation Of The Safety Of Liver Resection By Routine Liver Function Examination And Multi-slice Spiral CT Examination

Object: The hepatectomy is the clinical common technique, how enhances its surgery security is one of clinical research focal points.Methods: In this article, we retrospected and followed up 27 cases of which undergone hepatectomy from January 2009 to March 2010 in China-Japan union hospital of JiLin university hospital.These case were divided into group by the liver function after hepatectomy , all the patient has taken multi-slice spiral CT examination. data was analysised by t test (p=0.05).Results:After the hepatectomy, the liver function commutation not entire group age is bigger than the commutation good group, and the liver function commutation not entire group patients merge the chronic liver disease proportion (12/12) to be higher than the commutation good group (6/15). Compared with the liver function commutation not entire group and the commutation during good group ALB, TB, AST, the PALB difference has statistics significance, but ALT, ALP, CHE, PT in two groups of not obvious differences. Uses SSD, MIP, the VRT three way reconstruction image to be able the clear display liver blood vessel, effect of using SSD to displayâ…¢level or above minute vessel is not as good as ueing MIP or VRT. This group of CT obtains the liver volume slightly is smaller than according to the formula computation Chinese adult standard liver volume. Compared with the CT obtains plans the excision liver volume or the tumer volume and the actual value is not obvious difference. The Logistic single factor analysis prompt age, ALB, TB, AST, AlT, PALB and CT estimated relative residual liver volume are the risk facter about the liver function commutation not entire after hepatectomy. The Logistic multi-factor stepwise regression analysis demonstration only then low PALB and low CT estimated relative residual liver volume are the two two independence hazard factor about the liver function commutation not entire after hepatectomy.Conclusion: After liver excision surgery the patient who liver function is Child-Pugh A level before the hepatecyomy, the liver function restores well. The MSCT liver blood vessel three dimensional image formation can show the blood vessel organizes the construction and walks in the liver,also can help the surgeon get the information about the relation between the tumer and the blood,that can reduced hepatectomy's risk and blindness,maybe help to value the hemorrhage risk in the hepactomy. Using the MSCT technology may exact measurement liver volume, plan to excise the liver volume and the liver neoplasm volume,using these to computation obtained actual remnant liver volume percent have the guiding sense to the liver function commutation restores after the liver excision surgery.
