  • Title: Indication for, and valuation of computed tomography following anterior resection of the rectum.
    Author: Bauer WM, Wirsching R, Sommer B, Rath M, Fenzl G, Lissner J.
    Journal: Eur J Radiol; 1982 Feb; 2(1):35-7. PubMed ID: 7084239.
    Abstract:
    During a controlled study, 55 patients who had an anterior resection of the rectum were thoroughly examined, including by computed tomography. The results verified the following statements: 1. The use of CT as a screening-method for early detection of local tumour recurrence following anterior resection of the rectum appears not to be justified. 2. CT is indicated: a) if there is a laboratory or clinical suspicion of recurrence, despite normal findings on proctoscopy; b) to clarify the question of extramural extension if recurrence has been established by proctoscopy. 3. Following anterior resection of the rectum, CT normally demonstrates no remarkable development of scar tissue, unless the anastomosis is inadequate. 4. Following anterior rectal resection every indefinable tissue thickening in the pelvis must be considered a possible tumour recurrence and must be further investigated by needle biopsy.
