Definition / general
  • Ulceration of colonic mucosa secondary to impacted feces
Essential features
  • Inspissated feces can cause rectosigmoid ulceration in elderly patients
  • May perforate and lead to death
  • Usually in rectosigmoid
  • Impacted feces stagnate, eventually eroding and ulcerating underlying mucosa
Clinical features
  • Proposed criteria for stercoral perforation: round/ovoid antimesenteric perforation > 1 cm, associated with fecaloma, showing necrosis/ulcer/chronic inflammation microscopically (Dis Colon Rectum 2000;43:991)
