To evaluate the ability of endoscopic ultrasound (EUS)-guided fine needle aspiration biopsy (FNAB) to diagnose gastric duplication cysts.
FNAB reports from the Department of Pathology, Saint Louis University Hospital, were retrospectively searched for reports of EUS-guided FNABs of the stomach. These reports were then reviewed to find instances in which gastric duplication cysts were diagnosed. The charts of patients diagnosed with gastric duplication cysts were reviewed.
Two patients were identified. The first was a 35-year-old, Caucasian male with an asymptomatic submucosal (versus extrinsic) gastric mass discovered during computed tomography of the abdomen. The second was a 44-year-old, Caucasian male with a history of treated low grade B cell lymphoma of mucosa-associated lymphoid tissue (MALToma) who was found to have an asymptomatic gastric wall abnormality by EUS when undergoing follow-up for the MALToma. Respiratory-type epithelial cells were present in each of these gastric duplication cysts. At this writing, both patients were being followed clinically and with imaging.
Gastric duplication cysts, particularly those that have respiratory-type epithelium, can be diagnosed by EUS-guided FNAB. The diagnosis of gastric duplication cysts by EUS-guided FNAB can preclude surgery, with its associated morbidity.
评估内镜超声（EUS）引导下细针穿刺活检（FNAB）诊断胃重复囊肿的能力。
对圣路易斯大学医院病理科的FNAB报告进行回顾性检索，以查找胃EUS引导下FNAB的报告。然后对这些报告进行审查，以找出诊断为胃重复囊肿的病例。对诊断为胃重复囊肿的患者病历进行了审查。
确定了两名患者。第一名是一名35岁的白人男性，在腹部计算机断层扫描期间发现无症状的黏膜下（相对于外在性）胃肿物。第二名是一名44岁的白人男性，有黏膜相关淋巴组织低度B细胞淋巴瘤（MALToma）治疗史，在对MALToma进行随访时，经EUS发现有一无症状的胃壁异常。在这些胃重复囊肿中均存在呼吸型上皮细胞。撰写本文时，两名患者均在接受临床和影像学随访。
胃重复囊肿，尤其是那些具有呼吸型上皮的囊肿，可通过EUS引导下的FNAB进行诊断。通过EUS引导下的FNAB诊断胃重复囊肿可以避免手术及其相关的发病率。
