Trial summary
Gastrointestinal vascular malformation (GIVM), which is an important cause of acute or chronic gastrointestinal bleeding, consequently is in dire of effective treatment.

About this study
Official title: the Efficiency of Endoscopic Treatment for Recurrent Small Intestinal Bleeding Due to Gastrointestinal Vascular Malformation: the Study of the Bleeding Risks Stratification Model and Endoscopic Treatment
Gastrointestinal vascular malformation (GIVM), which is an important cause of acute or chronic gastrointestinal bleeding, consequently is in dire of effective treatment. The investigators' previous study first confirmed thalidomide treatment of GIVM bleeding was safe and effective. This trial intends to investigate the efficiency of endoscopic intervention to the hemorrhage due to GIVM. What more, the research tends to suggest standardizing clinical paths for small bowel bleeding due to GIVM.
Read the detailed description
This multi-institutional clinical trial investigates the efficacy of endoscopic intervention to the recurrent small intestinal hemorrhage due to GIVM. Patients with recurrent bleeding (>2 times for one year) will undergo balloon assisted enteroscopy and be treated with endoscopic therapy if necessary. The hierarchical primary endpoints were the difference in yearly Bleeding times, followed (if significant) by the difference in Blood Transfusions, Total Transfused Red Cell Requirements, yearly bleeding Episodes, Bleeding Duration, yearly average Hemoglobin (Hb) level, hospitalization and iron requirement. The study will be done at 10 centers in China.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
balloon assisted enteroscopyDevice
Patients with recurrent bleeding (>2 times for one year) will undergo balloon assisted enteroscopy and be treated with endoscopic therapy if necessary. Currently available endoscopic modalities are argon laser, bipolar electrocoagulation (BiCAP), band ligation, cryotherapy, radiofrequency ablation and argon plasma coagulation (APC). Among these options, APC is the most promising.

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2019; AzTrials last refreshed its copy on 7 Nov 2026.
