超声内镜在胰腺肿瘤诊治中的应用

Applications of endoscopic ultrasonography in the diagnosis and treatment of pancreatic tumors

胰腺肿瘤的诊治一直是临床医生的挑战之一,与传统影像学相比,超声内镜对于不同类型胰腺肿瘤的鉴别往往具有更高的敏感性和特异性,已在临床中起到重要作用。同时,超声内镜引导下穿刺活检也为进一步明确胰腺占位的诊断提供了极具参考意义的病理信息。另一方面,基于超声内镜基础上所发展出的介入治疗,如超声内镜引导下消融术等,也为胰腺肿瘤的治疗提供了更多可能性。此文从超声内镜对胰腺肿瘤的鉴别诊断价值,以及超声内镜引导下针对不同类型胰腺肿瘤的多种介入治疗方法做一评述。

The diagnosis and treatment of pancreatic tumors has been a challenging task for clinicians.As compared with traditional imaging modalities,endoscopic ultrasonography(EUS)offers higher sensitivity and specificity in identifying different types of pancreatic tumors and has played an important role in clinical practices.At the same time,EUS-guided biopsy provides significant pathological information for confirming a diagnosis of pancreatic space occupying lesions.On the other hand,interventional therapy based upon EUS,such as EUS-guided ablation,also provides more therapeutic options for pancreatic tumors.This review summarized the value of EUS in the differential diagnosis of cystic and solid pancreatic masses,benign and malignant pancreatic masses,as well as various interventional treatments for different types of pancreatic tumors under the guidance of EUS.
