经导管栓塞治疗胃肠间质瘤合并消化道出血的17例临床疗效分析

  目的  探讨经导管栓塞治疗胃肠间质瘤合并消化道出血的临床疗效。  方法  将2006年6月?2019年6月因消化道出血于我院行经导管栓塞治疗的17例胃肠间质瘤患者纳入研究，回顾性分析栓塞治疗的技术成功率和临床成功率。  结果  17例患者在栓塞治疗前行血管造影，5例（29.4%）显示肿瘤染色及造影剂外溢，9例（52.9%）显示肿瘤染色但没有明显造影剂外溢，3例（17.6%）显示阴性。14例血管造影阳性患者经导管栓塞治疗后13例（76.5%）技术成功，1例（5.9%）技术失败，予急诊剖腹探查行根治性切除；3例血管造影阴性患者技术弃权。13例技术成功患者中，12例（70.6%）获得临床成功，1例（5.9%）发生反复消化道出血，经保守治疗后好转。无1例患者发生栓塞术后并发症。栓塞术后随访30 d死亡率为0。  结论  经导管栓塞治疗胃肠间质瘤合并消化道出血是一种安全、有效的微创技术方法。

Efficacy of Transcatheter Embolization for Gastrointestinal Stromal Tumor with Gastrointestinal Hemorrhage in 17 Cases

  Objective  To evaluate the clinical efficacy of transcatheter embolization for patients with gastrointestinal stromal tumor and gastrointestinal hemorrhage.  Methods  From June 2006 to June 2019, 17 patients with gastrointestinal stromal tumor and who were gastrointestinal bleeding treated with transcatheter embolization due to gastrointestinal hemorrhage in our hospital were included in this study. The technical and clinical success rates and clinical success rate were analyzed retrospectively.  Results   Among 17 patients who underwent angiography before embolotherapy, 5 patients (29.4%) showed tumor staining and contrast extravasation, 9 patients (52.9%) showed tumor staining but no significant contrast extravasation, and 3 patients (17.6%) were negative. 14 patients had with positive angiographic findings and then underwent transcatheter embolization. Technical success was achieved in 13 patients (76.5%). Of the 13 technically successful patients, 12 patients(70.6%) achieved clinical success, one patient (5.9%) suffered from repeated gastrointestinal bleeding, which was improved after conservative treatment. No embolization-related complication occurred. The 30-day mortality rate was 0%.  Conclusion  Transcatheter embolization for gastrointestinal stromal tumor with gastrointestinal hemorrhage is a safe and effective minimally invasive technique.
