RESUMO
Objective@#To evaluate the value of super microvascular imaging(SMI) for evaluating the effect of interventional therapy of liver cancer.@*Methods@#A total of 30 patients with 40 leisions were enrolled in this study, from the tumor intervention department in the third affiliated hospital of suzhou university.This patients were underwent TACE, after the treatment 1 month, CDFI, SMI, and CT were study respectively. Using the continuity correction McNemar matching chi-square test, with P < 0.05 for the standard , CDFI and SMI shows the difference in monitoring the microvascular imaging in and around the tumors leisions.@*Results@#A total of 30 patients, 12 cases were primary liver cancer (7 cases combined with liver cirrhosis), 18cases were metastatic liver cancer; 30 cases including 25 single and 5 multiple. Significant difference were found between CT and SMI in detecting blood flows inside the lesion (χ² = 8.642 9, P < 0.05), and were also found between CT and CDFI in detecting blood flows inside the lesion (χ² = 16.961 5, P < 0.05). The AUROC, sensitivity, specificity, accuracy, PPV and NPV of CDFI were 0.647, 29.4%、100%、29.4%、100%、20.0%, while in SMI were 0.809, 61.8%、100%、61.7%、100%、31.5%, respectively.@*Conclusions@#SMI SMI can detect the microvascular inside the lesions. This new method was superior to CDFI, achieving the same effect as CT.
RESUMO
Cholangiocarcinoma is a malignancy of biliary tract and its incidence has been increasing in recent years all over the world.Meanwhile,there have been advances in techniques for its diagnosis and treatment.Some new methods such as PET,endoscopic ultrasonography and scopic CT can promote the diagnostic rate in the early stage and they have been used for diagnosis and staging of tumors.For those patients with large cholangiocarcinoma in the liver,photodynamic therapy is an effective neoadjuvant treatment.For those patients with unresectable cholangiocarcinoma,organ transplantation might be employed. Classification of cholangiocarcinoma and study on its diagnosis are important for disease evaluation in patients with the disease.
RESUMO
Functional delayed gastric emptying,also calls gastric paralysis,often occurs after abdominal operation,which severely affect patients prognosis.The mechanism,clinical manifestation,diagnosis,preservation and treatment are summarized in this review.
