Diagnostic Imaging Pathways - Irritable Bowel Syndrome (Suspected)

{tab=Pathway Home}

Population Covered By The Guidance

This pathway provides guidance on imaging in patients with non-specific or undifferentiated chronic abdominal pain who are suspected of having a functional bowel syndrome. ‘Alarm features’ and other indications for investigation are described.

Date reviewed: December 2012

Date of next review: 2017/2018

Quick User Guide

Move the mouse cursor over the PINK text boxes inside the flow chart to bring up a pop up box with salient points.
Clicking on the PINK text box will bring up the full text.
The relative radiation level (RRL) of each imaging investigation is displayed in the pop up box.

SYMBOL RRL EFFECTIVE DOSE RANGE
No radiation None 0
Minimal radiation Minimal < 1 millisieverts
Low radiation Low 1-5 mSv
Medium radiation Medium 5-10 mSv
High radiation High >10 mSv

Diagnosis of Irritable Bowel Syndrome (IBS)

MANNING CRITERIA 1,3

  1. Abdominal Pain relieved by defecation
  2. Looser stools with the onset of pain
  3. More frequent stools with the onset of pain
  4. Abdominal distension
  5. Passage of mucous
  6. Feeling of incomplete defecation (tenesmus)

ROME I CRITERIA 1

  1. Altered stool frequency
  2. Altered stool form
  3. Altered stool passage
  4. Passage of mucous
  5. Bloating or distension

Alarm symptoms 1,4

ACG Task Force also stated in their review that the overall accuracy of alarm symptoms although poor, the presence of any should warrant consideration for further investigations 1
