Transarterial embolisation for gastroduodenal bleeding following endoscopic resection

Area of Science:

• Interventional Radiology
• Gastroenterology
• Vascular Surgery

Background:

• Gastrointestinal bleeding is a significant complication following endoscopic resection.
• Transcatheter arterial embolisation (TAE) is a common treatment for gastrointestinal bleeding.

Purpose of the Study:

• To evaluate the safety and efficacy of TAE for managing bleeding after endoscopic mucosal resection and endoscopic submucosal dissection.
• To assess TAE outcomes in both immediate and delayed post-resection bleeding scenarios.

Main Methods:

• Retrospective review of 15 patients undergoing TAE for gastroduodenal bleeding post-endoscopic resection (November 2001 - December 2020).
• Analysis of patient demographics, clinical presentations, angiographic findings, and TAE procedures.
• Inclusion of cases with both positive and negative angiographic findings for bleeding.

Main Results:

• Technical and clinical success rates for TAE were 93.3% (14/15 patients).
• Eleven patients had positive angiographic findings; all bleeding arteries were embolised successfully.
• Four patients with negative angiographic findings also showed successful outcomes with empirical TAE.

Conclusions:

• TAE is a safe and effective treatment for both immediate and delayed gastrointestinal bleeding after endoscopic resection.
• Empirical TAE for angiographically negative bleeding sites is effective and carries no significant complications.
