Colonic mural thickening is often a finding in standard computed tomography (CT) scans of the abdomen. It often presents clinician with a dilemma on when a further endoscopic evaluation is needed, especially in the absence of guidelines. The aim of this systematic review is to evaluate the significance of bowel wall thickening and to assess its correlation with endoscopy.
This systematic review will be reported in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) 2015 statement. The search strategy will initially be developed in MEDLINE and adapted for use in EMBASE, MEDLINE, NHS evidence and TRIP. Two reviewers will independently conduct a study selection, data extraction and risk of bias assessment for the screened studies.
Data synthesis will be conducted using Review Manager software 5.3. The outcome of any dichotomous data will be presented as relative risk with confidence intervals.
It is extremely useful for the practising clinician to know which patients need further endoscopic evaluation. Even though there are several studies on this issue, none of them have attempted to produce a systematic review. We hope this systematic review will provide a substantiate evidence for future clinical practice.
