On careful examination, it turned out to be intussusception of colonic growth through anal canal. Contrast Enhanced Computed Tomography showed features of colonic obstruction. Sigmoidal growth intussuscepting through anal canal is extremely rare with only 9 cases being reported in Literature till date. He underwent sigmoidectomy with Hartman’s procedure uneventfully.
