食管支架术后急性致命性出血危险因素分析

Analysis of risk factors of acute fatal haemorrhage caused by esophageal stent placement

目的分析食管支架术后急性致命性出血危险因素。方法纳入6例食管内支架置入术患者。临床观察致命性出血事件并评估患者的临床特征。结果所有食管支架植入术均顺利完成,成功率100.0%。既往放疗病史和食管气管瘘的患者比例分别是66.7%(4/6)和50%(3/6),病变位于食管中段的患者比例为66.7%(4/6)。所有患者短期内均死于致命性大出血。结论放疗、食管气管瘘、食管解剖部位是导致食管支架置入术后致命性出血的风险因素。

Objective To analyze the risk factors of acute fatal haemorrhage caused by esophageal stent placement. Methods A total of 6 patients who received esophageal stent placement were enrolled. The clinical fatal heamorrhage e- vents were observed and the clinicsl features of the cases were evaluated. Results All the cases of esophageal stent placement were successful and the rate was 100. 0%. The proportion of patients with previous history of radiotherapy and tracheoesophageal fistula were 66.7 % （4/6）and 50% （3/6）, respectively. The proportion of patients which the lesions were located in the middle esophagus was 66.7% （4/6）. All patients died on account of the fatal haemorrhage in shortterm. Conclusion Radiotherapy, tracheoesophageal fistula and anatomic site of esophagus are the common risk factors of the fatal haemorrhage after esophageal stent placement.
