Randomized Controlled Trial
Perioperative Colonic Evaluation in Patients with Rectal Cancer; MR Colonography Versus Standard Care.
Preoperative colonic evaluation is often inadequate because of cancer stenosis making a full conventional colonoscopy (CC) impossible. In several studies, cancer stenosis has been shown in up to 16%-34% of patients with colorectal cancer. The purpose of this study was to prospectively evaluate the completion rate of preoperative colonic evaluation and the quality of perioperative colonic evaluation using magnetic resonance colonography (MRC) in patients with rectal cancer. ⋯ MRC is a valuable tool and is recommended as part of the standard preoperative evaluation for patients with rectal cancer.
