Laparoscopic excision of a retrorectal schwannoma.

Retrorectal tumors are uncommon and are usually managed by open surgical excision. Recent advances in laparoscopic techniques have led to the use of laparoscopy for a variety of problems in colorectal surgery, including the excision of retrorectal tumours. This case report, which describes the laparoscopic excision of a benign schwannoma arising from the second sacral nerve root, highlights the benefits of accurate preoperative diagnosis with MR imaging and the advantages of a laparoscopic approach while pointing out principles that should be adhered to when using this approach. The tumour was successfully resected without neural compromise and with a prompt and full postoperative recovery.
