Three-dimensional laparoscopy-assisted bowel resection for cavernous hemangioma of the rectum: Report of two cases.

The safety and feasibility of 3-D laparoscopy-assisted bowel resection were demonstrated in the management of rectal cancer. However, this procedure's role in the management of patients with diffuse cavernous hemangioma of the rectum has not been evaluated. Here, two patients were diagnosed with diffuse cavernous hemangioma of the rectum by colonoscopy and abdominal imaging. One case underwent pull-through transection and coloanal anastomosis in 3-D laparoscopy-assisted surgery. In another patient, 3-D laparoscopy-assisted abdominoperineal resection was performed. The operations were safely performed in both cases. The two patients recovered uneventfully, and satisfactory postoperative outcomes were demonstrated. This report shows that 3-D laparoscopy-assisted bowel resection may be safe and feasible for patients with diffuse cavernous hemangioma of the rectum.
