Abstract:

Objective To explore the clinical characteristics and diagnostic and therapeutic strategies of colonic telangiectasia. Methods A retrospective analysis was conducted on the clinical data of a patient with colonic telangiectasia who presented with repeated gastrointestinal bleeding and anemia, and relevant literature was reviewed. Results A 56-year-old female patient presented with recurrent black stools and alternating fresh bloody stools. Colonoscopy showed extensive network-like, dendritic, and spider nevus-like capillary dilation in multiple locations around the mucosa from the cecum to the descending colon, with the maximum of approximately 5mm × 5mm. She was finally diagnosed with colonic telangiectasia. Conclusion Colonic telangiectasia, also known as colonic vascular dysplasia, is more common in elderly patients. It is mostly asymptomatic, and gastrointestinal bleeding is an occasional symptom. Electronic colonoscopy is an important diagnostic method for colonic telangiectasia, and lesions are more common in the right colon. Asymptomatic patients do not require treatment, and those with concurrent bleeding may consider medications or local hemostasis under endoscopy.
