Abstract:
Diffuse cavernous hemangioma of the rectosigmoid colon is an uncommon benign vascular lesion. We report 5 cases of diffuse cavernous hemangioma, focusing on the clinical features, diagnosis procedure and treatment. Five patients have undergone sphincter-saving procedures, 3 cases had coloanal sleeve anastomoses and 1 patient each had pull-through anastomosis and lower anterior resection. During the follow-up, which ranged from 3 to 10 years, 3 patients had no further anal bleeding and 2 patients had minor intermittent anal bleeding. Continence for normal stool was satisfactory in all patients. In conclusion, sphincter-saving procedure is most appropriate and curative approach for the treatment of diffuse cavernous hemangioma. Imaging study plays an important role in the diagnosis, preoperative staging and follow-up.
