The tunnel endoscopic technique is the treatment of choice for submucosal tumors. However, the use of tunnel endoscopy to diagnose adenocarcinoma of the esophagus originating from the submucosa has not been well studied.
A 74-year-old man who presented with dysphagia for half a year underwent a series of checks, such as gastroendoscopy, X-ray contrast examination of the upper digestive tract, endoscopic ultrasonography, high-resolution esophageal manometry, and positron emission computed tomography. It should be noted that the stenosis of the esophagus was too narrow for endoscopic ultrasound-guided fine needle aspiration. The cause remained undiagnosed. Eventually, the tunnel endoscopic technique was perform for the pathological examination in the submucosa and the final diagnosis was adenocarcinoma of the esophagus. The patient and family members chose expectant treatment due to the patient's age and the high costs of surgical treatment.
Tunnel endoscopy could be used to diagnose tumors. Moreover, we review the literature to provide guidance regarding the causes of esophagostenosis.
隧道内镜技术是治疗黏膜下肿瘤的首选方法。然而，使用隧道内镜诊断起源于黏膜下层的食管腺癌尚未得到充分研究。
一名74岁男性，因吞咽困难半年接受了一系列检查，如胃镜检查、上消化道X线造影检查、内镜超声检查、高分辨率食管测压和正电子发射计算机断层扫描。需要注意的是，食管狭窄过于严重，无法进行内镜超声引导下细针穿刺活检。病因仍未明确。最终，采用隧道内镜技术对黏膜下层进行病理检查，最终诊断为食管腺癌。由于患者年龄和手术治疗费用高昂，患者及其家属选择了保守治疗。
隧道内镜可用于诊断肿瘤。此外，我们回顾文献以提供关于食管狭窄病因的指导。
