Abstract

Diffuse cavernous haemangioma of the rectum (DCHR) is a rare benign lesion of vascular malformation. According to previous studies, the most reported major symptoms of DCHR are recurrent painless rectal bleeding or iron deficiency anaemia. We present a case of an 8 years and 11 months boy who was diagnosed with DCHR by magnetic resonance imaging. The patient underwent Laparoscopic-assisted transanal distal sigmoidectomy and sigmoido-anal anastomosis (Laparoscopic Swenson Procedure), and recovered well. After the operation, the child had short-term faecal incontinence and loose stools, which returned to normal after half a year. Regardless of age and symptoms, early and correct diagnosis and treatment of DCHR and postoperative restoration of normal anal function are necessary. Laparoscopic Swenson procedure may be a good option for the treatment of DCHR.
