Transanal Irrigation in Children: Treatment Success, Quality of Life, Adherence, Patient Experience, and Independence

To investigate the clinical effectiveness and patient experience of transanal irrigation (TAI) in children with constipation or fecal incontinence. Combined retrospective and cross-sectional study including pediatric patients who used a Navina TAI system. We retrospectively collected baseline characteristics and data on treatment success at 1- and 6-month follow-up (FU). Treatment success was defined as defecating at least 3 times per week and having less than 1 episode of fecal incontinence per week. We cross-sectionally assessed health-related quality of life (HRQoL), treatment adherence, treatment satisfaction (Treatment Satisfaction Questionnaire for Medication [TSQM]), illness perceptions, medication beliefs, and patient empowerment with validated questionnaires. Thirty-four patients were included (median age at start TAI: 11 years old [range, 6-18]), 32 in the retrospective review, and 26 in the cross-sectional survey (median of 3 years after initiation). Most patients were diagnosed with functional constipation (n = 26; 76%) or a neurogenic bowel disorder (n = 6; 18%). Treatment success rates significantly improved at each FU compared with baseline (baseline: 4/25 [16%]; 1-month FU: 12/16 [75%], P = 0.008; 6-month FU: 11/18 [61%], P = 0.016; cross-sectional FU: 13/26 [50%], P = 0.008). HRQoL scores were high (PedsQL median, 73 [IQR, 54-85]). Adherence (defined as Medication Adherence Report Scale [MARS] ≥ 23) was low (36%), whereas TSQM effectiveness scores were high (median, 69 [IQR, 47-86]). The majority of children (61%) reported an increase in independence since TAI treatment. Patient empowerment (GYPES) levels were similar to those reported in children with other chronic conditions. TAI with a Navina system is an effective bowel management system for children with intractable constipation or fecal incontinence.
