| 1. | Postoperative internal abdominal hernia : 27 cases
手术后腹内疝27例 |
| 2. | Transmesenteric and transmesocolic hernias account for 8 % of all internal hernias ( 1 ? 3 )
肠系膜疝和结肠系膜疝占所有腹内疝的8 % 。 |
| 3. | Because clinical diagnosis of internal hernias is difficult , imaging studies may play an important role if accurate and reliable ct findings can be obtained
由于临床诊断腹内疝很困难，如果能获取准确可靠的ct图像表现，那么它就能起到重要的作用。 |
| 4. | In conclusion , there are recognizable features of internal hernia on sonography . when such features are seen , a sonographic diagnosis of internal hernia can be made
总之，超声可以辨认腹内疝的特征。如果发现这些征象，超声可以做出腹内疝的诊断。 |
| 5. | However , ct evaluation of any type of internal hernia is rare in the radiology literature , except for a few reports on paraduodenal and transmesenteric hernias
然而，在放射文献中除了有几篇十二指肠旁疝和肠系膜疝的报道外，各种类型腹内疝的ct评估很少。 |
| 6. | Gastrointestinal studies enhanced with intraluminal contrast material ( barium - enhanced studies , enteroclysis ) and abdominal ct enable accurate diagnosis of any type of internal hernia ( 9 , 10 )
胃肠造影（钡剂增强检查，肠道造影检查）和腹部ct能准确的诊断各种类型的腹内疝。 |
| 7. | Preoperative diagnosis is difficult because clinical symptoms may range from intermittent and mild digestive complaints to acute - onset intestinal obstruction
由于腹内疝的临床症状的表现差别很大，可以是间歇性和轻度消化不适，也可以表现为急性发作的肠梗阻，所以术前诊断很困难。 |
| 8. | Internal hernias are silent if they are easily reducible , but the majority often cause epigastric discomfort , periumbilical pain , and recurrent episodes of intestinal obstruction ( 3 , 5 )
腹内疝如果易于复原则可以不表现症状，但绝大多数导致上腹不适、脐周疼痛和反复发作的肠梗阻。 |
| 9. | Pdhs constitute approximately 53 % of all internal hernias . approximately three - fourths of these hernias occur on the left and are more predominant in men than in women , with a ratio of about 3 : 1 ( 1 ? 3 )
十二指肠旁疝占所有腹内疝的53 % ，大约四分之三发生于左侧，男性比女性明显好发，两者的比率约3 1 。 |
| 10. | Internal hernias are clinically apparent only when incarcerated internal hernias result from small bowel obstruction ( sbo ) ; therefore , a delay in diagnosis may lead to strangulation and an increased risk of serious complications
腹内疝仅在小肠梗阻（ sbo ）发展到腹内疝嵌钝才表现出明显的临床症状，因此，延误诊断可导致肠绞窄并增加其他严重并发症的危险性。 |
