*9.4.2 Water-soluble contrast enema*

Current evidence is not consensual about the best imaging method for CAL diagnosis, but **water-soluble contrast enema** (WSCE) and contrasted CT scan (CCT) are the most used techniques. Some authors consider WSCE was less precise, with a significantly higher rate of false positives than digital rectal examination [143]. Others defended the systematic use of WSCE, emphasizing its advantages and providing relevant information on lower rectal anastomoses [144].
