Introduction: Primary tumors in the gastrointestinal tract are frequently located at the rectum. Proper treatment depends on staging. Endoscopic ultrasound has a clear role in the preoperative staging of rectal cancer. It permits a good definition of the rectal wall layers and therefore examines the tumor deepness (T) and the extension to lymph nodes (N). Aim of the study: to use the staging of rectal tumor as a tool for therapeutic decisions and asses its utility. Patients and methods: 115 studies were evaluated for rectal tumors with endoscopic ultrasound between January 1999 and March 2005, 58 females and 57 males with a mean age of 60±13 years. All tumors had a TNM staging classification with endoscopic ultrasound. A therapeutic approach was advised after classification. Results: From 115 studies: 74 (64%) had a previous histology and 57 (77%) had a diagnosis of rectal adenocarcinoma. Endoscopic ultrasound diagnosed 64 rectal carcinomas, the rest of the patients had anal cancer n=5, anorectal cancer n=9, epidermoid rectal tumor n=5, polypoid mucosal lesions n=8, rectal metastasis n=3, stromal tumors n=2, rectosigmoid tumors n=10 , rectal stenosis n=2 and no tumor definition n=7. After endoscopic ultrasound 67 patients had a therapeutic suggestion: radiotherapy, chemotherapy and/or surgery with posterior endoscopic ultrasound control n=40, fine needle aspiration with endoscopic ultrasound n=8, endoscopic mucosal resection n=7 and other therapies n=11 Conclusions: endoscopic ultrasound staging of rectal tumors and other pathologies may be helpful in the selection of a definitive therapeutic approach including neo adjuvant therapy.
