“…Third, although previous studies have used comparable viscerosensory questionnaires to investigate visceral perception in IBS (7,24), further validation of our questionnaire should be undertaken (greater refinement of questions with involvement of patients, reliability, and validity testing etc). However, preliminary studies using the pediatric version of our questionnaire also show differences in viscerosensory perception between children with CC and healthy children (41,42). Although the viscerosensory questionnaire may seem complex to use on a day-to-day basis in clinical practice, our intention is to develop a user-friendly interface with simple binary output (normal vs abnormal viscerosensory urge perception).…”

INTRODUCTION: Although the association of absent or attenuated "call to stool" with constipation is well-recognized, no studies have systematically evaluated the perception of urge to defecate in a well-defined cohort of patients with chronic constipation (CC). METHODS:A prospective study of 43 healthy adult women and 140 consecutive adult women attending a tertiary center for investigation of CC. All participants completed a 5-day viscerosensory questionnaire, and all women with CC also underwent anorectal physiologic investigations. Normal urge perception and abnormal urge perception were defined using a Naive Bayes model trained in healthy women (95% having normal urge). RESULTS:In total, 181 toilet visits in healthy women and 595 in women with CC were analyzed. Abnormal urge perception occurred in 70 (50.0%) women with CC. In this group, the urge to defecate was more often experienced as abdominal sensation (69.3% vs 41.4%; P < 0.0001), and the viscerosensory referral area was 81% larger (median pixels anterior: 1,849 vs 1,022; P < 0.0001) compared to women with CC and normal urge perception. Abnormal (vs normal) urge in women with CC was associated with more severe constipation (Cleveland Clinic constipation score: 19 vs 15 P < 0.0001), irritable bowel syndrome (45.7% vs 22.9% P < 0.0001), and a functional evacuation disorder on defecography (31.3% vs 14.3% P 5 0.023). A distinct pattern of abnormal urge was found in women with CC and rectal hyposensitivity.DISCUSSION:Abnormal urge perception was observed in 50% of women with CC and was frequently described as abdominal sensation, supporting the concept that sensory dysfunction makes an important contribution to the pathophysiology of constipation.

OBJECTIVE. We examined the literature to identify reports of sensory integration concerns in children with functional defecation issues and to explore whether difficulty processing sensation may be related to their challenging bowel management behaviors. METHOD. A scoping review was used to address the research question. We sourced articles from six databases in three languages, searched reference lists of all included articles, and identified additional articles through discussion with experts in the field. RESULTS. Twelve articles were included in the final synthesis, identifying 15 challenging behaviors potentially related to sensory integration concerns. CONCLUSION. We summarize research documenting sensory integration concerns in children with functional defecation issues, providing researchers and clinicians with an overview of the current state of understanding.
