  • It has enabled to avoid surgical treatment which should be carried out in these cases in which long-term conservative treatment failed.[ncbi.nlm.nih.gov]

Prognosis

  • Where this is successful, the prognosis is good. However, in 3-4% of cases, colonic perforation complicates the presentation 2 and this and its sequelae significantly increase both mortality and morbidity.[radiopaedia.org]
  • Prognosis Prognosis, even if treated, is uncertain due to damage caused by the acute phase of infection. Between 25 and 30% of those who are infected will have severe and possibly fatal pathology.[patient.info]
  • Prognosis : guarded depending on stage of disease and choice of treatment. Pathogenesis Etiology Often idiopathic - dysfunction of colonic smooth muscle, progressive post-receptor defect in excitation-contraction coupling.[vetstream.com]
  • Prognosis Overall, prognosis is very good. Most infants with Hirschsprung's disease achieve good bowel control after surgery, but a small percentage of children may have lingering problems with soilage or constipation.[healthofchildren.com]
  • Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis.[rarediseases.org]

Etiology

  • It can also be classified according to etiology ( 1, 2 ). We aimed to characterise the clinical and diagnostic features of a patient with idiopathic rectosigmoid megacolon.[ispub.com]
  • Pathogenesis Etiology Often idiopathic - dysfunction of colonic smooth muscle, progressive post-receptor defect in excitation-contraction coupling. Secondary to colonic obstruction: Extraluminal compression, eg pelvic fracture.[vetstream.com]

Epidemiology
