Case ReportTransanal total mesorectal excision as a surgical procedure for diffuse cavernous hemangioma of the rectum: A case report

- DCHR is a rare benign vascular tumor, with the most common symptom being rectal bleeding.
- The main challenge in the surgical management of DCHR lies in the precise resection of distal rectum.
- TaTME appears to be a safe and feasible procedure for patients with DCHR in experienced hands.

BackgroundThe safety and feasibility of transanal total mesorectal excision (TaTME) were demonstrated in the management of rectal cancer. However, its role in the management of patients with diffuse cavernous hemangioma of the rectum (DCHR) has not been evaluated.MethodsA female patient with DCHR was admitted to our hospital. Colonoscopy, magnetic resonance imaging (MRI), abdominal computed tomography (CT) and arteriography were performed. Lesions were detected in mesorectum and rectal wall extending from the dentate line to 5 cm proximally. TaTME with a protecting loop ileostomy were performed. The research work has been reported in line with the SCARE criteria Agha et al., 2016 [1].ResultsTaTME and a protecting loop ileostomy were safely performed, with an intact mesorectal specimen being harvested. The entire procedure took 348 min. The estimated blood loss was 100 ml. The patient recovered uneventfully. Her symptom of painless rectal bleeding was resolved satisfactorily following the surgery. The histopathological evaluation confirmed the diagnosis of DCHR.ConclusionsTaTME appears to be a safe and feasible procedure for patients with DCHR in experienced hands.
