Despite being a well-described diagnostic procedure for more than ten years, endoscopic ultrasonography (EUS) is not generally widespread in Denmark. This review deals with the present indications for EUS. For some diseases, EUS has found its precise place in the diagnostic strategy. However, in other diseases, it is not yet clear where to put EUS in relation to other diagnostic procedures.
BACKGROUND: One of the concerns after rectal cancer surgery is the local recurrence rate. Randomized trials have shown that the best local control rate for rectal cancer patients overall is obtained by a short preoperative course of radiotherapy followed by a total mesorectal excision, but there are however subgroups of rectal cancer patients with varying risks of recurrences. DISCUSSION: At one end of the continuum are patients with stage I disease who are at very low risk of local recurrence. At the other end are the patients with locally advanced tumor who are at very high risk, and who would benefit from a more extensive neoadjuvant treatment schedule. This kind of differentiated treatment can be performed only when there is an accurate tool to identify preoperatively the different risk groups. There is recent evidence, suggesting that MRI can serve for this purpose, because it accurately predicts the tumor free circumferential resection margin at TME. CONCLUSION: This article provides a literature review of the value of preoperative imaging in rectal cancer surgery.
