Endobronchial ultrasound-guided fine needle aspiration (EBUS-FNA) is emerging as a critical technology in the evaluation of mediastinal lesions and is increasingly regarded as complementary to endoscopic ultrasound (EUS) in this arena. This complementary role may extend into the abdomen in cases where esophageal strictures prevent the passage of the echoendoscope. The objective of the study was to characterize the uses of EBUS-FNA in the evaluation of gastrointestinal lesions in patients with esophageal narrowing. The study design was a single-center case series. The setting was in a tertiary referral center. Four patients underwent EBUS-FNA to evaluate gastrointestinal lesions; esophageal strictures prevented EUS passage in three, the fourth patient did not tolerate transbronchial EBUS but had abdominal lesions within reach of the EBUS scope. EBUS was used to evaluate the liver, adrenal gland, a retroperitoneal mass, and a celiac axis lymph node. EBUS-FNA has greater potential to evaluate abdominal lesions than has been previously recognized. The EBUS scope represents a safe and readily available technology to evaluate patients with esophageal strictures. Interventional endoscopists should be exposed to this modality.
经支气管超声引导针吸活检术（EBUS-FNA）在纵隔病变的评估中崭露头角，且在该领域逐渐被视为内镜超声（EUS）的补充。在食管狭窄妨碍超声内镜通过的情况下，这种互补作用可能会扩展到腹部。本研究的目的是描述 EBUS-FNA 在评估食管狭窄患者胃肠道病变中的应用。研究设计为单中心病例系列。该研究在一家三级转诊中心进行。4 名患者接受 EBUS-FNA 以评估胃肠道病变；3 名患者因食管狭窄而无法进行 EUS 检查，第 4 名患者无法耐受经支气管 EBUS，但有可触及的腹部病变。EBUS 用于评估肝脏、肾上腺、腹膜后肿块和腹腔干淋巴结。与之前的认识相比，EBUS-FNA 更有潜力评估腹部病变。EBUS 内镜代表了一种安全且易于获得的技术，可用于评估食管狭窄患者。介入内镜医生应接触这种方式。
