Colonic pseudo-obstruction is a clinical and radiological syndrome of the large bowel dilatation without mechanical obstruction. We report two similar clinical cases of this syndrome with different origins – adult Hirschsprung’s disease and Ogilvie’s syndrome. Both conditions are rare and actual prevalence is unknown. Early recognition and management are extremely important because it can prevent occurrence of such complications as ischemia, volvulus or perforation and reduce morbidity with mortality.
