Diffuse cavernous hemangioma of the rectosigmoid colon.

Area of Science:

• Gastroenterology
• Surgical Oncology
• Vascular Surgery

Background:

• Diffuse cavernous hemangioma (DCH) of the rectosigmoid colon is a rare, benign vascular malformation.
• This condition can present with significant symptoms, including anal bleeding, necessitating effective treatment strategies.

Observation:

• This study reports on five cases of DCH, detailing clinical presentations, diagnostic methods, and treatment outcomes.
• Patients underwent various sphincter-saving procedures, including coloanal sleeve anastomosis, pull-through anastomosis, and lower anterior resection.

Findings:

• All five patients underwent successful sphincter-saving procedures.
• Post-operative follow-up (3-10 years) showed resolution of anal bleeding in three patients and minor intermittent bleeding in two.
• Bowel continence was satisfactory in all treated patients.

Implications:

• Sphincter-saving procedures are identified as the most appropriate and curative treatment for rectosigmoid DCH.
• Advanced imaging plays a crucial role in diagnosis, preoperative staging, and post-treatment follow-up of this condition.
