BACKGROUND: Gastrointestinal stromal tumors (GIST) of the rectum are a challenge for the colorectal surgeon. In case of a locally advanced rectal GIST, an extended or multivisceral resection with significant morbidity and -mortality is often necessary. Literature is lacking on the combined modality of transanal endoscopisc microsurgery (TEM) following imatinib for these patients. METHODS: We describe a combined approach for a locally advanced GIST of the rectum with preoperative imatinib -treatment and subsequent local excision using the TEM procedure. RESULTS: After six months of treatment with imatinib the TEM procedure was successfully performed with a radical -resection of the remnant tumor. Twenty-four months after surgery this patient has no evidence of disease. CONCLUSIONS: A TEM procedure following treatment with imatinib may safely be performed in selected patients with a locally advanced GIST.
