[Efficacy Analysis of Transcatheter Arterial Embolization in Acute Non-Variceal Upper Gastrointestinal Bleeding].

Objective: To evaluate the safety and effectiveness of transcatheter arterial embolization (TAE) in the treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB), and to guide clinical practice and continue to optimize diagnosis and treatment strategies.

Methods: This retrospective study included 266 patients who underwent angiography due to ANVUGIB between March 2016 and March 2021. Data on the positive rate of angiography, the technical success rate and clinical success rate of TAE, and the rebleeding rate and the all-cause mortality within 30 days after TAE treatment were collected, and the influencing factors relevant to the above events were analyzed accordingly.

[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.

[Role of Hemostatic Clips as Guidance during Transcatheter Arterial Embolization in Patients with Peptic Ulcer Bleeding after Endoscopic Treatment Failure].

Objective: To investigate the feasibility and clinical efficacy of transcatheter arterial embolization using hemostatic clips as the guidance in the patients with peptic ulcer bleeding after endoscopic treatment failure.

Methods: From February 2009 to October 2018, 33 patients with peptic ulcer bleeding who were treated with transcatheter arterial embolization after endoscopic treatment failure were included in the study. Clinical success rate, 30-d mortality rate and complication rate were observed.
