目的讨论研究内镜超声(EUS)-细针穿刺(FNA)在临床上用于诊断及治疗胰腺癌的实际临床价值。方法 32例胰腺癌疑似病例。医务人员在采用EUS确定患者胰腺占位性病变后,同时采用超声穿刺针进行FNA以获取患者病变的胰腺组织。对于2例胰腺癌晚期的且断定无手术价值的患者,医务人员在采用超声穿刺针进行FNA的时候为患者注入无水乙醇以阻滞患者的腹腔神经丛,达到缓解患者痛苦的目的。结果 32例患者的病情诊断中,医务人员采用EUS确诊出所有患者胰腺的占位性病变,且其中8例患者病变位于胰腺体尾部,其余24例患者的病变均位于胰腺头部。32例患者在进行EUS-FNA后均获得具有诊断价值的标本,其中26例患者均确诊为胰腺癌,其余6例患者为慢性胰腺炎。在对胰腺癌患者的治疗中,同时进行腹腔神经节的阻滞来缓解患者的疼痛,且均具有明显的效果。结论 EUS-FNA在临床上能够有效地诊断出患者胰腺的占位性病变,灵敏性高,特异性强,具有较高的准确度,还可向病变部位注入特殊药物进行治疗以及止痛,故EUS-FNA在临床上对于胰腺癌的诊断及治疗都具有极为重要的意义。 Objective To study the clinical value of endoscopic ultrasonography (EUS) - fine needle aspiration (FNA) in the diagnosis and treatment of pancreatic cancer. Methods 32 cases of suspected cases of pancreatic cancer. Medical staff to determine the use of EUS in patients with pancreatic space-occupying lesions, while the use of ultrasound puncture needle FNA to obtain the patient’s diseased pancreas. For 2 patients with advanced pancreatic cancer, who have no surgical value, the medical staff injecting absolute ethanol into the FNA to stop the patient’s celiac plexus can reduce the pain of patients. Results In the diagnosis of 32 patients, the medical staff used EUS to confirm the space-occupying lesions of pancreas in all patients. Among them, 8 patients had lesions located in the tail of the pancreas and the other 24 lesions located in the pancreas. Thirty-two patients had diagnostic value after EUS-FNA, of which 26 patients were diagnosed as pancreatic cancer and the other 6 patients were chronic pancreatitis. In the treatment of patients with pancreatic cancer, celiac ganglion block at the same time to relieve pain in patients, and have a significant effect. Conclusion EUS-FNA can effectively diagnose the occupying lesions of pancreas in patients with high sensitivity, specificity and high accuracy. It can also inject special drugs into the diseased parts for treatment and analgesia, so EUS-FNA -FNA in the clinical diagnosis and treatment of pancreatic cancer has a very important significance.
