Background/aimsFecal soiling (FS) is the staining of underwear without loss of significant amounts of fecal material. It is frequently associated with defecation disorders in children. The aim of this study was to search for psychological and clinical correlates of adult patients with soiling. Clinically, the complaint of staining is confused with that of fecal incontinence (FI) in the mind of both patients and attending physicians.DesignObservational studyPatients and methodWe included 1454 consecutive outpatients (71% females). They filled out the Rome III questionnaire for functional gastrointestinal disorders (FGIDs); Beck depression inventory, and state and trait anxiety questionnaires; and Likert scales for constipation, diarrhea, bloating, and abdominal pain. Data were analyzed using ANOVA and logistic regression analysis.ResultsSoiling was found in 123 patients (8.5%). They reported similar frequencies of esophageal, gastroduodenal, and abdominal pain as patients without soiling. In contrast, patients with soiling reported higher prevalence of IBS, such as IBS-Diarrhea, Mixed-IBS, functional diarrhea, functional constipation, and levator ani syndrome, and higher Likert scale for diarrhea, bloating, abdominal pain, and softer stools. The multivariable logistic regression analysis shows that patients with soiling have increased odds to report IBS (P = 0.019; OR = 1.958; 95% CI = [1.118–3.431]), functional diarrhea (P = 0.040; OR = 1.901; 95% CI = [1.028–3.513]), and high Diarrhea Likert scale (P < 0.001; OR = 1.215; 95% CI = [1.130–1.306]). No association was found with psychological evaluation.ConclusionIn FGID patients, soiling is not associated with psychological disorders and is mainly associated with IBS and functional diarrhea.
