Objective To evaluate the diagnosis value of spiral CT in leiomyosarcoma of abdomen.Methods Both plain and enhanced CT fingdings in 12 cases with pathologic-proved leiomyosarcoma of abdomen were respectively analyzed.Results In all of 12 cases,1 case occurred in colon,1 case in rectum,1 case in small intestine,5 cases in mesentery,4 cases in retroperitoneum,CT positioning accuracy rate was 91.7 ％ (11/12).The volume was comparatively large,the average diameter was 6 cm.The density were uneven,nodosity or lamellar necrosis were found.Delay enhacement were occurred in lower density part in most part of cases (9/12).Conclusion The localization of spiral CT is comparatively accurate to the leiomyosarcoma of abdomen,some characteristics are found in CT image,but the final diagnosis depends on immunohistochemistry.

Routine preoperative tests such as BT/CT, PT/PTT and CBC, could not test abnormal hemostasis that take drugs and health functional food. We used platelet function analyzer (PFA(R))-100, to evaluate preoperative bleeding tendencies. From November 2008 to February 2010, 306 surgical patients were tested preoperative PFA in our hospital. There are 2 tests in PFA(R)-100. The Pre Operative EPI (collagen/epinephrine) assay tests extrinsic platelet function, whereas the Pre Operative ADP (collagen/adenosine diphosphate) assay tests intrinsic platelet function. We divided normal and abnormal groups by the PFA(R)-100 assay tests. If either of results were abnormal in the two tests, the patient was divided to the abnormal group. 306 surgical patients were observed with hemorrhagic complications. All of the patients were divided normal and abnormal groups by the PFA(R)-100 test result. The normal group was made up of 286 (93.5%) patients, the abnormal group was made up of 20 (6.5%) patients. We observed each group hemorrhage complication including sever echymosis and hematoma, and analyzed each group complication rate. There were 9 (3.1%) cases of complication in the normal group. There were 3 (15.0%) cases of complication in the abnormal group. To evaluate preoperative bleeding tendency, PFA(R)-100 can be complementary examination with previous routine blood coagulation tests.
