Anal incontinence (AI) is defined as involuntary loss of faeces or flatus. Faecal incontinence is defined as a complaint of involuntary loss of solid or liquid faeces, while flatal incontinence is defined as a complaint of involuntary loss of flatus. [1] AI results in emotional, psychological and social problems. [2][3][4] Mechanical sphincter disruption and nerve damage occurring as a complication of childbirth contribute to the development of AI. [2][3][4][5][6][7] Studies suggest that obstetric factors increase the risk of damage to the anal sphincter and subsequent development of AI. [4][5][6] These include a prolonged second stage of labour, fetal macrosomia, posterior positions of the fetal skull, instrumental delivery, epidural analgesia, episiotomy and, most significantly, rupture of the anal sphincter. [2,4,7] Determining the true incidence of AI is often difficult, because women rarely volunteer information about symptoms unless specifically asked. [3][4][5] Variations in definitions, underlying causes and subjectivity of symptoms also impact on the incidence. [3,4] Furthermore many women only present with symptoms after the puerperium, or later.Prevalence rates vary from 13% to 44% between 6 weeks and 10 months after delivery in primiparous and multiparous women. [3][4][5] Up to 25% of primigravidas experience altered continence postnatally, with one-third having evidence of anal sphincter injury. [4,5] Most of the published data on AI involve studies performed on white women in high-income countries. There are minimal data from low-and middle-income countries (LMICs) like ours, where socioeconomic, demographic, racial, anatomical and histological variations may impact on obstetric risk factors and AI prevalence. We therefore performed a study in our population, which consists mainly of Zulu-speaking black Africans and Indians.The aim was to describe the prevalence of AI in our population antenatally and 6 weeks and 6 months after vaginal delivery or emergency caesarean section (CS) in late labour, and to explore the association between demographic and obstetric risk factors and AI.
MethodsThis prospective observational study was conducted at two regional hospitals (King Edward VIII Hospital and R K Khan Hospital) servicing the lower socioeconomic groups of the Durban metropolitan area in KwaZulu-Natal Province, South Africa.Women delivering vaginally or by emergency CS late in labour (N=1 254) were recruited over a 3-month period and followed up for 6 months. Participants completed a standardised AI symptom questionnaire on 3 occasions: antenatally or within 24 hours of delivery (information on the antenatal period), and 6 weeks and 6 months after delivery. The antenatal questionnaire was administered
Postpartum anal incontinence in a resource-constrained setting: Prevalence and obstetric risk factorsBackground. Postpartum anal incontinence (AI) is a common and debilitating condition, but data from resource-constrained settings are scarce. Objective. To show that AI is common in a resource-constrained...
