  "abstract": "Background The prevalence of constipation in children, affects between 0.7 and 29.6% of the general population in UK and worldwide, 1 2 and is frequently associated with faecal incontinence.3 The coexistence of functional constipation and faecal (FCFI) has been recognised within paediatrics.4 Aim We aim to compare subjective reporting using bowel questionnaire with objective findings (using high resolution anorectal manometry - HRAM).Methods A prospective maintained database was reviewed for patients in the service between September 2016- October 2024. Data regarding demographics, questionnaire (St Mark’s Incontinence Score - SMIS) and HRAM. SPSS was used to perform statistical analysis: median, range, percentages, and Pearson correlation (p value of <0.05 as significant).Results In total, 288 patients completed the SMIS questionnaire and underwent awake HRAM. 58% males; median age 10-year-old (range 1- 27 years); 27% with neurodiversity. There was no correlation between parents reporting and physiological findings (p>0.05). Refer to table 1 for findings.Abstract OC14 Table 1Compare subjective and objective findings Subjective reported symptoms (SMIS) Normal (SMIS) Abnormal (SMIS) Objective measurements (HRAM) Normal Sensation 54 (19%) 162(56%) Abnormal Sensation 17 (6%) 55 (19%) Conclusion Subjective findings do not correlate with objective HRAM findings.There is a gap between parental reporting of symptoms and objective HRAM findings.This gap could be explained by conscious denial (withholding), subconscious denial , impaired sensory processing (interoception), imperfect physiological testing and imperfect parental interpretation.This finding demonstrates the importance of objective testing for a condition that relies heavily on parental reporting of the patient’s symptom.References van den Berg MM, Benninga MA, Di Lorenzo C.
