[CT-guided interventions in diseases of the small pelvis following rectal resection].
60% of relapses of rectal cancer after abdominoperineal resection occurs at the site of the surgical intervention. Early detection of these recurrent tumours is vital. Among the up-to-date imaging systems CT is the most sensitive method in diagnosis of pelvic tumours. Despite the accurate imaging diagnosis the nature of lesions remains sometimes ambiguous. 11 CT guided biopsies and 2 punctures were performed because of suspected local recurrence or abscess. As a result of biopsies, local recurrence was histologically proven in 6 cases, fibrosis in 4, inflammatory disease in 1. Both punctures revealed the cytological diagnosis of abscess. There were no complications. The interventions were carried out in prone position through the greater sciatic foramen. In the knowledge of the exact anatomy of this region, the procedure can be performed safely by CT guidance and a correct diagnosis can be achieved.
