Study Of The Evaluation Of Anisodamine In CT Enterography

Objective:This paper aimed to investigate the value of anisodamine in CT enterography(CTE)and discuss the evaluation of enterography in small bowel tumor.Methods:Group A: choose 40 patients who met the requirements were selected and then equally divided into two groups,namely,experimental group and control group,respectively.The patients in the experimental group were intramuscularly injected by anisodamine while the patients in the control group received no anisodamine for blank control.Next,the luminal diameter,the intestinal wall thickness and the CT value of arterial phase and venous phase of the intestinal wall were measured,two independent-sample Wilcoxon W test was used;the small bowel dilatation scores were evaluated,two independent samples U test were adopted.Group B,retrospective analysis the suspicion small bowel tumor patients,who had proceeded the CTE examination at January 2015 to January 2017,and were all confirmed by operation pathology.Total of32 patients,include 9 gastrointestinal stromal tumors,10 lymphomas,9 small bowel adenocarcinomas,1 hemangioma,2 ectopic pancreas and 1 inflammatory pseudotumor measure the length of tumor,the ratio of lumen stenosis and the CT value of three-phases(plain phase,arterial phase and venous phase),respectively.According to the nature of the lesion,choose these patients into two groups,identify lymphoma to small bowel adenocarcinoma and identify malignant tumor to non malignant tumor.There are two part in the malignant tumor to non malignant tumor group.First part include all the malignant,second part exclude lymphomas.Two independent samples Wilcoxon W test was performed to these two groups,the criterion for statistical significance was set at P<0.05.Results:.For group A,at duodenum the comparisons of luminal diameter,the small bowel dilatation score and CT value of arterial phase between the experimental group and the control group showed statistical significance(P=0.000,P=0.017,P=0.015;P<0.05).At jejunum the small bowel dilatation score and CT value of arterial phase between the experimental group and the control group showed statistical significance(P=0.01,P=0.001;P<0.05).At ileum the small bowel dilatation score and CT value of arterial phase between the experimental group and the control group showed statistical significance(P=0.005,P=0.003;P< 0.05).The comparisons of the intestinal wall thickness and venous phase of the intestinal wall between the experimental group and the control group of duodenum,jejunum and ileum showed no statistical significance(P>0.05).For group B,the difference of tumor length,the ratio of lumen stenosis and the CT value of arterial-phases and venous-phase between lymphoma and adenocarcinoma showed statistical significance(P=0.001,P=0.001,P=0.007,P=0.014;P<0.05),but the CT value of plain phase showed no statistical significance(P=0.109,P>0.05).The difference between all the malignant tumor and non malignant tumor,the tumor length,the ratio of lumen stenosis and the CT value of plain-phases,arterial-phase and venous-phase showed statistical significance(P=0.004,P=0.009,P=0.012,P=0.010,P=0.016;P<0.05).The difference between malignant tumor exclude lymphomas and non malignant tumor,the tumor length,the ratio of lumen stenosis and the CT value of plain-phases,arterial-phase and venous-phase showed no statistical significance(P=0.295,P=0.642,P=0.218,P=0.0.79,P=0.235;P>0.05).Conclusion: 1.Anisodamine can improve the intestinal filling performances in CTE,which can more clearly present lesions.2.CTE have important evaluation to identify the nature of the small bowel tumor.
