Oesophageal, fully covered self-expanding metal stents (SEMS) allow palliation of dysphagia so as to support nutrition during neoadjuvant therapy. We present a 68-year old man with an oesophageal adenocarcinoma (T3N1M0) who had a fully covered oesophageal SEMS placed prior to neoadjuvant chemoradiotherapy. Repeat endoscopy 8 weeks later (for stent removal) showed that the stent had migrated and impacted upon the greater curvature of the stomach with a resultant ulcer. Surgery was delayed and, 10 weeks following the cessation of neoadjuvant chemoradiotherapy, this patient underwent a right thoracoabdominal oesophagogastrectomy. Operative findings included an erosion of the stent-induced gastric ulcer into the body of the pancreas and showed that the ulcerated tumour had become adherent to the thoracic aorta. This report demonstrates that the complications of stent migration can significantly impact upon surgical resection at multiple levels and provides a case for the routine removal of stents used in the neoadjuvant setting.
食管全覆膜自膨式金属支架(SEMS)可缓解吞咽困难,从而在新辅助治疗期间维持营养状况。我们报告一例68岁食管腺癌(T3N1M0)男性患者,在新辅助放化疗前放置了食管全覆膜SEMS。8周后重复内镜检查(为取出支架)发现支架移位并嵌顿于胃大弯处,导致溃疡形成。手术推迟,在新辅助放化疗结束10周后,该患者接受了右胸腹联合食管胃切除术。手术所见包括支架所致胃溃疡侵蚀至胰体,并显示溃疡型肿瘤已与胸主动脉粘连。本报告表明,支架移位并发症可在多个层面显著影响手术切除,并为常规取出新辅助治疗中使用的支架提供了一个病例依据。
