早期诊断和早期治疗是提高胰头癌治疗效果的关键。为探讨临床各种诊断手段在小胰头癌诊断中的意义，回顾分析了８４例根治性手术中肿瘤≤２ｃｍ和＞２ｃｍ两组患者间的临床表现、影像学检查、血清学检查结果及其在小胰头癌诊断中的地位和作用。临床首现症状以黄疸、上腹部痛常见，但组间无差异。ＥＲＣＰ的诊断准确率明显高于Ｂ超（Ｐ＜０．０５）和ＣＴ（Ｐ＞０．０５），同时对小胰头癌的敏感性均高于Ｂ超（Ｐ＜０．０５）和ＣＴ（Ｐ＞０．０５），而Ｂ超和ＣＴ在诊断２ｃｍ以上胰头癌时有较高的确诊率。ＣＡ１９－９对小胰头癌的敏感性高于ＣＥＡ（Ｐ＜０．０１），但早期的确诊率仅为４２％。作者认为，重视胰头癌的临床表现是早期诊断的基础，合理的选择影像学检查是提高小胰头癌诊断准确率的关键，ＥＲＣＰ是诊断小胰头癌的有效手段。
Early diagnosis and early treatment are the key to improving the therapeutic effect of pancreatic cancer. In order to explore the significance of clinical diagnostic methods in the diagnosis of small pancreatic head cancer, the clinical manifestations, imaging findings, and serological findings of 84 patients with tumors ≤2cm and >2cm were retrospectively analyzed. The status and role in the diagnosis of small pancreatic head cancer. The first clinical symptoms were common with jaundice and upper abdominal pain, but there was no difference between the groups. The diagnostic accuracy of ERCP was significantly higher than that of B-ultrasound (P<0.05) and CT (P>0.05), and the sensitivity of small pancreatic head cancer was higher than that of B-ultrasonography (P<0.05) and CT. (P>0.05), B-CT and CT have higher diagnosis rate in diagnosing pancreatic head cancer above 2cm. The sensitivity of CA19-9 to small pancreatic head cancer was higher than that of CEA (P<0.01), but the early diagnosis rate was only 42%. The authors believe that the importance of the clinical manifestations of pancreatic cancer is the basis for early diagnosis. Reasonable selection of imaging examination is the key to improve the accuracy of diagnosis of small pancreatic head cancer. ERCP is an effective means for diagnosing small pancreatic head cancer.
