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.
