Coloanal sleeve anastomosis in the treatment of diffuse cavernous haemangioma of the rectum: long-term results.

Diffuse cavernous haemangioma of the rectum is an unusual lesion. In 1971 Parks and co-workers described resection and coloanal sleeve anastomosis as an alternative operation in the treatment of this rare malformation. The clinical presentation, diagnosis and long-term results of patients with this condition managed by such a surgical technique are described. Resection and coloanal sleeve anastomosis offers major advantages such as a lower risk of intraoperative bleeding, no risk of damaging the pelvic nerves, sparing of continence and avoidance of a permanent colostomy. It should therefore be considered the treatment of choice for this uncommon condition.
