Core Tip
Core Tip: Colonic anastomotic varices are extremely rare, particularly in patients without cirrhosis or portal hypertension, and optimal management has not been established. We describe a unique case of recurrent bleeding from transverse colonic anastomotic varices after colectomy, in which several endoscopic attempts at hemostasis were unsuccessful. Angiography revealed localized venous congestion at the anastomosis, prompting targeted embolization using a transhepatic interventional radiological approach. This case underscores the need to consider anastomotic varices as a potential late postoperative bleeding source and shows that coordinated treatment planning across multiple specialties is essential for selecting the most appropriate therapeutic strategy.
