To study fluoroscopic placement of covered expandable stent tubes in patients with esophagogastric strictures.
Under fluoroscopic guidance, 132 stent tubes were placed in 116 patients with malignant neoplasm; four, in three patients with benign lesions. All patients had aphagia or dysphagia to soft food or liquid.
After placement (successful in 100% of cases), 93 (78%) of the patients could ingest solid food; 24 (20%), soft food. Complications in the 119 patients included blockage in 13, stent tube migration in 12, gastroesophageal reflux in nine, severe pain in nine, and delayed massive bleeding in four. Most major complications were managed by means of a balloon catheter, a second stent tube, or analgesics. One hundred four patients died 2-80 weeks after stent placement.
Treatment with placement of a covered expandable stent tube is effective in most patients with dysphagia due to malignant esophogastric strictures and is less effective in patients with benign strictures.
研究在食管胃狭窄患者中经荧光镜放置覆膜可扩张支架管。
在荧光镜引导下，为116例恶性肿瘤患者放置了132根支架管；为3例良性病变患者放置了4根。所有患者均有吞咽困难，无法吞咽固体食物或流食。
放置后（100%成功），93例（78%）患者能够摄入固体食物；24例（20%）患者能够摄入软食。119例患者出现的并发症包括13例堵塞、12例支架管移位、9例胃食管反流、9例剧痛和4例迟发性大出血。大多数主要并发症通过球囊导管、第二根支架管或镇痛药处理。104例患者在支架放置后2至80周死亡。
对于大多数因恶性食管胃狭窄导致吞咽困难的患者，放置覆膜可扩张支架管治疗有效，而对良性狭窄患者效果较差。
