In severe ulcerative colitis (UC), gastrointestinal (GI) distension indicates a higher risk for toxic megacolon (TMC) and need for surgery. Persistent GI distension predicts poor response to medical therapy and increased risk of complications.

Area of Science:

  • Gastroenterology
  • Internal Medicine
  • Clinical Research

Background:

  • Severe ulcerative colitis (UC) poses significant risks, including toxic megacolon (TMC) and multiple organ dysfunction syndrome (MODS).
  • Previous studies suggested gastrointestinal (GI) distension as a marker for severe UC complications.

Purpose of the Study:

  • To prospectively evaluate the prevalence of GI distension in severe UC patients.
  • To assess the relationship between GI distension and clinical outcomes, including complications and need for surgery.

Main Methods:

  • Prospective evaluation of 45 inpatients with severe UC.
  • Assessment of GI distension using plain abdominal films.
  • Monitoring for clinical improvement, complications (TMC, MODS), surgery, and mortality.

Main Results:

  • 53% of severe UC patients exhibited GI distension.
  • Patients with GI distension had a higher incidence of TMC and required surgery.
  • Multiple organ dysfunction syndrome (MODS) was a key predictor of fatal outcomes.

Conclusions:

  • Persistent GI distension in severe UC identifies patients with poor medical response and increased risk of TMC and surgery.
  • MODS development is the most critical factor for fatal outcomes in severe UC.
