<jats:title>ABSTRACT</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>To determine the prevalence of obstetric anal sphincter injuries (OASIS) in a cohort of primiparous women and to evaluate their association with demographic, obstetric and ultrasound parameters.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>This was a retrospective analysis of the ultrasound volume datasets of 320 primiparous women, acquired at 5 months postpartum. Tomographic ultrasound imaging (TUI) was used to evaluate the external anal sphincter (EAS). A significant EAS defect was diagnosed if a defect of > 30° was seen in four or more of six TUI slices bracketing the EAS.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Significant EAS defects were found in 69 women (27.9% of those delivered vaginally). In nine of those a third‐degree tear was diagnosed intrapartum and was sutured. In 60 women with significant defects there was no documentation of sphincter damage at birth, implying unidentified or occult defects (60/69, 87.0%). Among them, 29 had had a second‐degree tear, two a first‐degree tear and three an intact perineum. In 31 cases an episiotomy had been performed, with five extensions to a third‐degree tear. On multivariate analysis only forceps delivery was significantly associated with OASIS.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>In this cohort of primiparous women we found OASIS in 27.9% of vaginally parous women, most of which had not been diagnosed in the delivery suite. There seems to be a need for better education of labor‐ward staff in the recognition of OASIS. On the other hand, it is conceivable that some defects may be masked by intact tissue. The significance of such defects remains doubtful. Forceps delivery was the only identifiable risk factor. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.</jats:p></jats:sec>

<jats:title>Abstract</jats:title><jats:sec> <jats:title>Purpose</jats:title> <jats:p>Bowel complaints are very common among patients with colorectal cancer. However, the most used questionnaires for colorectal cancer survivors do not comprehensively comprise bowel symptoms. This study aimed to examine construct and criterion validity, as well as internal consistency, of the Chilean Version of the International Consultation on Incontinence Questionnaire Bowel Module (ICIQ-B) among people with colorectal cancer.</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>Cross-sectional, validation study performed with 106 colorectal cancer patients from Hospital del Salvador, Chile. Bowel function was assessed with the ICIQ-B. Construct validity was assessed with confirmatory factor analysis and hypothesis testing. Specific items of a quality-of-life questionnaire (EORTC QLQ-CR29) were used to correlate with similar ICIQ-B items for criterion validity. For internal consistency, Cronbach’s alpha was computed.</jats:p> </jats:sec><jats:sec> <jats:title>Results</jats:title> <jats:p>For construct validity, the confirmatory factor analysis showed that the three factors model did not fit our data. Meanwhile, hypothesis testing favored the construct validity of the instrument, considering that rectal cancer patients showed worse bowel pattern (p = 0.001), bowel control (p = 0.001) and quality of life (p < 0.001) scores compared to colon cancer patients. In addition, those patients assessed before surgery also presented worse scores bowel control (p = 0.023) and quality of life (p = 0.009) compared to post-surgical patients. Regarding criterion validity, the ICIQ-B items showed a significant correlation with similar QLQ-CR29 items. The internal reliability of the instrument was good (Cronbach’s α = 0.909).</jats:p> </jats:sec><jats:sec> <jats:title>Conclusion</jats:title> <jats:p>Considering that this questionnaire appraises bowel function in more depth, it is recommended for use in clinical practice and research with colorectal cancer patients.</jats:p> </jats:sec>

<jats:title>Abstract</jats:title><jats:p> Purpose To describe the English-to-Spanish translation process and preliminary psychometric analysis (face validity, cultural adaptation, and test-retest reliability) of the International Consultation on Incontinence Questionnaire – Bowels Module (ICIQ-B) among Chilean colorectal cancer patients.</jats:p><jats:p> Materials and Methods The face validity was studied with 10 colorectal cancer patients, and the test-retest reliability, with 15 patients, 1 month before and 6 months after cancer surgery.</jats:p><jats:p> Results Two rounds of translation/back translation resulted in a Spanish version. The English expression open your bowels was translated as defecar, as it is easily understandable in Spanish. The patients reported that the instrument was easy to answer, with clear instructions, and that it was adequate to appraise their health condition. The test-retest reliability was good (Spearman rho [ρ] ≥ 0.842); only item 15a, the Bristol Stool Scale, obtained a moderate correlation (ρ = 0.639). The patients reported a variety of symptoms, including increased bowel movements, nocturnal bowel movements, fecal urgency, and incontinence.</jats:p><jats:p> Conclusions The first Spanish version of the ICIQ-B was culturally adapted for Chilean colorectal cancer patients, and showed good test-retest reliability. It might be a reference for other Spanish-speaking countries and for patients with other conditions. The ICIQ-B is a robust comprehensive questionnaire for bowel function.</jats:p>
