Laparoscopic excision of large lower rectal gastrointestinal stromal tumour (GIST): A case report.

Gastrointestinal stromal tumour (GIST) involving rectum is rare. No definite method of treatment has been established because of a small number of cases being reported. It is usually managed with invasive or ablative surgery, such as abdominoperineal resection (APR). The acceptance of minimally invasive (laparoscopic) surgery in colorectal disease plays a pivotal role in improving the postoperative quality of life. We report a case of a large lower rectal GIST who underwent laparoscopic excision of tumour through a subserosal approach whilst preserving the anal sphincter and without any rectal resection.
