Ninety-eight patients with hemorrhage from esophageal varices(EVH),were ramdomly divided into three groups,treated with sandostatin (group A),pitressin combined with nitroglycerin(group B)and Sengstaken-Blakemores tube(group C).The studies were comducted by putting a gastric canal into the stomach of patiento(group A and B)before medical treatment and observing drain' s color every rifteen minutes,and measuring pylic insids diameter(PID),blood flow speed (BFS)and blood flow volume(BFV)of these patients with...

Ninety-eight patients with hemorrhage from esophageal varices(EVH),were ramdomly divided into three groups,treated with sandostatin (group A),pitressin combined with nitroglycerin(group B)and Sengstaken-Blakemores tube(group C).The studies were comducted by putting a gastric canal into the stomach of patiento(group A and B)before medical treatment and observing drain' s color every rifteen minutes,and measuring pylic insids diameter(PID),blood flow speed (BFS)and blood flow volume(BFV)of these patients with Doppler ultrasound detecting method The results showed that,hemostatic rates of guoup A(63.41%)and C(72.00 % )in 24 hours, were significantly higher than that of group B(37.50 %,P<0.01),but group A were not statistically different from group C(P>0.05),average hemostatic time of group A were markedly shorter than that of troup B(P<0. 01).After the treatment,averate PID and BFV were signiticantly reduced(P<0.01),and BFS were puickened in both group A and B. Howener,PID, BFS and BFV after treatment in group C were not changed significantly. These results suggested thaf therapeutic effect was confirmed in the patients with VEH by sandostatin, which might be more efficime than that with pitressin combined with nitroglycerin One of machanesms in the treatment of EVH with sandostatin might be associated with reduction of visceral blood flow and portal venous pressure.contraction of pylic inside diameter.

应用善得定治疗41例门脉高压症食管静脉曲张破裂出血患者,同时以32例垂体后叶素加硝酸甘油治疗组和25例双囊三腔管治疗组为对照。定时观察治疗后鼻胃管内引流物颜色至24h。彩色多谱勒超声波测定门静脉主干内经、血流速度及血流量。结果表明,善得定组24h止血率与三腔管组比较虽无显著性差异,而显著高于垂体后叶组(P<0.01),其平均止血时间比垂体后叶素组显著缩短(P<0.01)。善得定组和垂体后叶素组治疗后门静脉内径较治疗前皆显著缩小(P<0.01),血流量也较治疗前显著减少(P<0.01),血流速度比治疗前显著增快(P<0.01)。而三腔管组治疗前后静脉内径、血流速度均无显著性差异(P>0.05)。这些结果表明,善得定对门脉高压症食管静脉曲张破裂出血治疗效果是肯定的,其疗效优于垂体后叶素和硝酸甘油联合治疗,其止血机制可能与减少门静脉血流量、降低其压力和收缩门静脉血管有关。

Objective:To determine the acuracy and clinical significance of lesser omentum sac abnormality observed by ultrasound in acute pancreatitis (AP).Methods:Six hundred and twenty seven AP patients examined by ultrasound were studied retrospectively during Jan 1996 to Dec 1998 One hundred cases accepted CT scan Results:The sensitivity, specificity and accuracy of ultrasound detecting lesser omentum sac fluid collection were 62 5%,91 5% and 87 3% respectively , and for tissue necrosis...

Objective:To determine the acuracy and clinical significance of lesser omentum sac abnormality observed by ultrasound in acute pancreatitis (AP).Methods:Six hundred and twenty seven AP patients examined by ultrasound were studied retrospectively during Jan 1996 to Dec 1998 One hundred cases accepted CT scan Results:The sensitivity, specificity and accuracy of ultrasound detecting lesser omentum sac fluid collection were 62 5%,91 5% and 87 3% respectively , and for tissue necrosis were 87 5%,97 1% ,96 4% respectively.In mild AP,the incidence rate of fluid collection and tissue necrosis were 18 1% and 1 8% while in severe AP were 58 4% and 29 6% respectively.The hospital period was quite different for patients with and without fluid collection,26 9 and 14 8 days respectively Conclusions:Lesser omentum sac fluid collection and tissue necrosis can be detected by ultrasound accurately.The most common site of peripancreatic necrosis was lesser omentum sac.The fluid collection of lesser omentum sac was closely related to both the severity of AP and the hospital period.

目的 :了解急性胰腺炎 (AP)时超声观察网膜囊病变的准确性及其临床意义。方法 :回顾分析了本院三年中 6 2 7例 AP的超声检查资料 ,其中 10 0例行 110次 CT检查 ,通过与 CT比较分析超声诊断网膜囊病变的准确性 ;与临床资料比较分析 AP时网膜囊出现病变的意义。结果 :超声诊断网膜囊积液的敏感性、特异性及准确性分别为 6 2 .5 %、 91.5 %、 87.3% ;诊断网膜囊坏死组织则分别为 87.5 %、 97.1%、 96 .4%。在轻症胰腺炎中 ,网膜囊积液及坏死组织的出现率为 18.1% ,1.8% ;在重症胰腺炎中 ,则为 5 8.4%及 2 9.6 %。有网膜囊积液组平均住院日为 2 6 .9天 ,而无网膜囊积液组为 14.8天。结论 :网膜囊是胰周坏死组织最常出现的部位 ;网膜囊积液与 AP的轻重及住院时间长短有关 ;超声能较准确地诊断网膜囊积液及坏死组织

All cases were confirmed by surgery and pathology. The accuracy rate of ultrasound diagnosis of colon carcinoma is 91.5% . Conclusion Ultrasound examination should be performed pre - operation routinely in colon carcinoma patient, for it is economy , easy to perform and no limit to patient s age or health condition.

目的 评估结肠癌的超声诊断价值。材料对50例此例病人做回顾性研究。方法 经腹部常规超声探测。结果 超声显示假肾性或分布不匀的癌物质图像。所有病例均经过手术和病理验证。结肠的超声诊断率为91.5%。结论 对于结肠癌病人应进行手术前常规超声探测,因为这样经济,易于操作,同时以病人的年龄及身体状况限制较小。
