Flow chart showing the type and result of radiological examination for suspected anastomotic leakage (N = 91) in a group of 429 patients who underwent an ileocolonic, colo-colonic or colorectal anastomosis. Radiological results are correlated with clinical presence or absence of anastomotic dehiscence. CT computed tomography, CR contrast radiography, plus sign radiological signs of leakage, minus sign no radiological signs of leakage, relap relaparotomy
