Current practice in the care of children with functional constipation: What is the hold up?

OBJECTIVES: For children with intractable functional constipation (FC), there are no evidence-based guidelines for subsequent evaluation and treatment. Our objective was to assess the practice patterns of a large, international cohort of pediatric gastroenterologists. METHODS: We administered a survey to physicians who attended the 2nd World Congress of Pediatric Neurogastroenterology and Motility held in Columbus, Ohio (USA) in September 2023. The survey included 29 questions on diagnostic testing, nonpharmacological and pharmacological treatment, and surgical options for children with intractable FC. RESULTS: Ninety physicians from 18 countries completed the survey. For children with intractable FC, anorectal manometry was the most commonly used diagnostic test. North American responders were more likely than Europeans to use stimulant laxatives (97% vs. 77%, p = 0.032), prosecretory medications (69% vs. 8%, p < 0.001), and antegrade continence enemas (ACE; 83% vs. 46%, p = 0.009) for management. Europeans were more likely than North Americans to require colonic transit testing before surgery (85% vs. 30%, p < 0.001). We found major differences in management practices between Americans and the rest of the world, including use of prosecretory drugs (73% vs. 7%, p < 0.001), anal botulinum toxin injections (81% vs. 58%, p = 0.018), ACE (81% vs. 58% p = 0.018), diverting ileostomies (56% vs. 26%, p = 0.006), and colonic resections (42% vs. 16%, p = 0.012). No differences were found when respondents were compared by years of experience. CONCLUSIONS: Practice patterns in the evaluation and treatment of children with intractable FC differ widely among pediatric gastroenterologists from around the world. A clinical guideline regarding diagnostic testing and surgical decision-making is needed.

What are Normal Defecation Patterns in Healthy Children up to Four Years of Age? A Systematic Review and Meta-Analysis.

OBJECTIVE: To summarize available data on defecation frequency and stool consistency of healthy children up to age 4 in order to estimate normal references values. STUDY DESIGN: Systematic review including cross-sectional, observational, and interventional studies published in English, that reported on defecation frequency and/or stool consistency in healthy children 0-4 years old. RESULTS: Seventy-five studies were included with 16 393 children and 40 033 measurements of defecation frequency and/or stool consistency. Based on visual inspection of defecation frequency data, a differentiation was made between two age categories: young infants (0-14 weeks old) and young children (15 weeks-4 years old). Young infants had a mean defecation frequency of 21.8 per week (95 % CI, 3.9-35.2) compared with 10.9 (CI, 5.7-16.7) in young children (P < .001). Among young infants, human milk-fed (HMF) infants had the highest mean defecation frequency per week (23.2 [CI, 8.8-38.1]), followed by formula-fed (FF) infants (13.7 [CI 5.4-23.9]), and mixed-fed (MF) infants (20.7 [CI, 7.0-30.2]). Hard stools were infrequently reported in young infants (1.5%) compared with young children (10.5%), and a reduction in the frequency of soft/watery stools was observed with higher age (27.0% in young infants compared with 6.2% in young children). HMF young infants had softer stools compared with FF young infants. CONCLUSIONS: Young infants (0-14 weeks old) have softer and more frequent stools compared with young children (15 weeks-4 years old).

Fatal gastrointestinal complications in Pitt-Hopkins syndrome.

Pitt-Hopkins syndrome (PTHS) is a rare neurodevelopmental disorder caused by mutations of the transcription factor 4 (Tcf4) gene. Individuals with PTHS often suffer from severe abdominal bloating and constipation. In this short communication, we discuss two individuals with PTHS who died unexpectedly due to gastrointestinal complications. We aim to increase awareness among healthcare professionals who care for individuals with PTHS, to ensure adequate screening and management of gastrointestinal symptoms in this population. Moreover, we discuss how fatal gastrointestinal complications may be related to PTHS and provide an overview of the literature.

Accuracy of Anorectal Manometry to Detect the Rectoanal Inhibitory Reflex in Children: Awake Versus Under General Anesthesia.

OBJECTIVES: Our objective was to investigate if there is a difference in the detection of the rectoanal inhibitory reflex (RAIR) when an anorectal manometry (ARM) is performed awake or under general anesthesia. METHODS: A retrospective review of ARM studies was performed to identify children who had undergone ARMs both while awake and under general anesthesia. We compared ARM outcomes including the detection of the RAIR and anal canal resting pressure. RESULTS: Thirty-four children had received ARMs both while awake and under general anesthesia (53% female, median age at first ARM 7.5 years [range 3-18 years]). In 9 of 34 (26%) children the RAIR was solely identified during ARM under general anesthesia and not during ARM while awake. In 6 of 9 (66%) this was unrelated to the balloon volumes used during balloon inflations. In 4 of 34 (12%) children, assessment of the RAIR was inconclusive during ARM under general anesthesia due to too low, or loss of anal canal pressure. In 2 of those children, ARMs while awake showed presence of a RAIR. Anal canal resting pressures were higher during ARM while awake versus ARM under general anesthesia (median 70 [interquartile range, IQR 59-85] vs 46 mmHg [IQR 36-65] respectively, P < 0.001). CONCLUSIONS: General anesthesia may affect the detection of a RAIR in 2 ways. On the one hand, it may facilitate better visualization in children in whom a RAIR could not be visualized while awake. On the other hand, it may cause a loss of anal canal pressure resulting in an inconclusive test result.

Long-Term Outcomes of Antegrade Continence Enemas to Treat Constipation and Fecal Incontinence in Children.

OBJECTIVES: The objective of this study is to investigate long-term outcomes of antegrade continence enema (ACE) treatment in children with constipation or fecal incontinence. METHODS: Prospective cohort study including pediatric patients with organic or functional defecation disorders who started ACE treatment. Data were collected at baseline and at follow-up (FU) from 6 weeks until 60 months. We assessed parent and patient-reported gastrointestinal health-related quality of life (HRQoL) using the Pediatric Quality of Life Inventory Gastrointestinal Symptoms Module (PedsQL-GI), gastrointestinal symptoms, adverse events, and patient satisfaction. RESULTS: Thirty-eight children were included (61% male, median age 7.7 years, interquartile range 5.5-12.2). Twenty-two children (58%) were diagnosed with functional constipation (FC), 10 (26%) with an anorectal malformation, and 6 (16%) with Hirschsprung disease. FU questionnaires were completed by 22 children (58%) at 6 months, 16 children (42%) at 12 months, 20 children (53%) at 24 months, and 10 children (26%) at 36 months. PedsQL-GI scores improved overall with a significant increase at 12- and 24-month FU for children with FC and a significant increase in parent reported PedsQL-GI score at 36-month FU for children with organic causes. Minor adverse events, such as granulation tissue, were reported in one-third of children, and 10% of children needed a surgical revision of their ACE. The majority of all parents and children reported that they would "probably" or "definitely" choose ACE again. CONCLUSION: ACE treatment is perceived positively by patients and parents and can lead to long-term improvement in gastrointestinal HRQoL in children with organic or functional defecation disorders.

Time to first passage of meconium and defecation frequency preceding necrotizing enterocolitis in preterm infants: a case-control study.

Necrotizing enterocolitis (NEC) is associated with significant morbidity and mortality in preterm infants. Early recognition and treatment of NEC are critical to improving outcomes. Enteric nervous system (ENS) immaturity has been proposed as a key factor in NEC pathophysiology. Gastrointestinal dysmotility is associated with ENS immaturity and may serve as a predictive factor for the development of NEC. In this case-control study, preterm infants (gestational age (GA) < 30 weeks) were included in two level-IV neonatal intensive care units. Infants with NEC in the first month of life were 1:3 matched to controls based on GA (± 3 days). Odds ratios for NEC development were analyzed by logistic regression for time to first passage of meconium (TFPM), duration of meconial stool, and mean daily defecation frequency over the 72 h preceding clinical NEC onset (DF < T0). A total of 39 NEC cases and 117 matched controls (median GA 27 + 4 weeks) were included. Median TFPM was comparable in cases and controls (36 h [IQR 13-65] vs. 30 h [IQR 9-66], p = 0.83). In 21% of both cases and controls, TFPM was ≥ 72 h (p = 0.87). Duration of meconial stool and DF < T0 were comparable in the NEC and control group (median 4 and 3, resp. in both groups). Odds of NEC were not significantly associated with TFPM, duration of meconial stools, and DF < T0 (adjusted odds ratio [95% confidence interval]: 1.00 [0.99-1.03], 1.16 [0.86-1.55] and 0.97 [0.72-1.31], resp.). CONCLUSION: In this cohort, no association was found between TFPM, duration of meconium stool, and DF < T0 and the development of NEC. WHAT IS KNOWN: • Necrotizing enterocolitis (NEC) is a life-threatening acute intestinal inflammatory disease of the young preterm infant. Early clinical risk factors for NEC have been investigated in order to facilitate early diagnosis and treatment. • Signs of disrupted gastrointestinal mobility, such as gastric retention and paralytic ileus, have been established to support the diagnosis of NEC. Nevertheless, defecation patterns have insufficiently been studied in relation to the disease. WHAT IS NEW: • Defecation patterns in the three days preceding NEC did not differ from gestational age-matched controls of corresponding postnatal age. Additionally, the first passage of meconium and the duration of meconium passage were comparable between cases and controls. Currently, defecation patterns are not useful as early warning signs for NEC. It remains to be elucidated whether these parameters are different based on the location of intestinal necrosis.

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

OBJECTIVES: To investigate the clinical effectiveness and patient experience of transanal irrigation (TAI) in children with constipation or fecal incontinence. METHODS: 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. RESULTS: 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. CONCLUSIONS: TAI with a Navina system is an effective bowel management system for children with intractable constipation or fecal incontinence.

Quality of Life in Children with Functional Constipation: A Systematic Review and Meta-Analysis.

OBJECTIVE: To systematically review the literature on health-related quality of life (HRQoL) in children with functional constipation and to identify disease-related factors associated with HRQoL. STUDY DESIGN: The Pubmed, Embase, and PsycINFO database were searched. Studies were included if they prospectively assessed HRQoL in children with functional constipation according to the Rome criteria. Articles were excluded if patients had organic causes of constipation and if HRQoL was only assessed after successful therapeutic interventions. A meta-analysis was performed calculating sample size-weighted pooled mean and SD of HRQoL scores. The quality of the studies was also assessed. RESULTS: A total of 20 of 2658 studies were included, providing HRQoL data for 2344 children. Quality of evidence was considered to be poor in 9 of the 20 studies (45%); 13 of the 20 studies reported sufficient data to be included in the meta-analysis. Pooled total HRQoL scores of children with functional constipation were found to be lower compared with healthy reference samples (65.6 vs 86.1; P < .01). Similar HRQoL scores were found according to self-report and parent proxy report. Hospital-based studies reported lower HRQoL scores as compared with community-based studies. Two studies reported on HRQoL scores of children with and without fecal incontinence, but no significant difference was found. CONCLUSIONS: HRQoL is compromised in children with functional constipation.

Prevalence of Functional Defecation Disorders in Children: A Systematic Review and Meta-Analysis.

OBJECTIVE: To systematically review the literature regarding the epidemiology of functional constipation and functional nonretentive fecal incontinence (FNRFI) in children. Secondary objectives were to assess the geographical, age, and sex distribution of functional constipation and FNRFI and to evaluate associated factors. STUDY DESIGN: The Cochrane Library, PubMed, and Embase databases were searched from 2006 until September 2017. The following inclusion criteria were applied: (1) prospective studies of population-based samples; (2) reporting on the prevalence of functional constipation or FNRFI according to the Rome III/IV criteria; (3) in children aged 0-18 years; and (4) published in full manuscript form. A quality assessment of included studies was conducted. Random effect meta-analyses with meta-regression analyses of study characteristics were performed. RESULTS: Thirty-seven studies were included, of which 35 reported on the prevalence of functional constipation and 15 of FNRFI. The reported prevalence of functional constipation ranged from 0.5% to 32.2%, with a pooled prevalence of 9.5% (95% CI 7.5-12.1). The prevalence of FRNFI ranged from 0.0% to 1.8%, with a pooled prevalence of 0.4% (95% CI 0.2-0.7). The prevalence of functional constipation was 8.6% in boys compared with 8.9% in girls (OR 0.99, 95% CI 0.9-1.4). Geographical location, dietary habits, and exposure to stressful life events were reported to be associated with the prevalence of functional constipation. Data on FNRFI were scarce and no associated factors were identified. CONCLUSION: Functional constipation is common in childhood and is associated with geographical location, lifestyle factors, and stressful life events. FNRFI is rare, and no associated factors were identified.

Awareness and Implementation of the 2014 ESPGHAN/NASPGHAN Guideline for Childhood Functional Constipation.

OBJECTIVE: The aim of the study was to assess whether physicians approach children with functional constipation according to the 2014 European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN)/North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) guideline. METHODS: We invited pediatricians and pediatric gastroenterologists in the Netherlands and the United States to participate in this anonymous survey using a self-developed questionnaire containing 19 multiple choice questions concerning evaluation and treatment of children with constipation. RESULTS: We included 328 physicians (67% from the United States, 34% from the Netherlands). The majority of US responders (53%) worked in primary care, whereas all Dutch responders worked in a hospital. In total, 31% of responders were not familiar with the guideline (38% US responders vs 16% Dutch responders, P < 0.001). Perianal inspection was frequently ("often" or "always" on a 5-point Likert scale) conducted by 78% of responders. Digital rectal examination was frequently done by 42%. Inquiry about sexual abuse was made by 18%. Commonly reported reasons for omitting these items were perceived patient or parental discomfort. Most frequently implemented initial nonpharmacological interventions included a toilet training program (89%), optimizing fluid and fiber intake (86% and 81%), a defecation diary (62%), and a reward system (60%). Polyethylene glycol was the most prescribed medication for disimpaction (68%) and maintenance treatment (57% for infants, 97% for children ≥1 year). CONCLUSIONS: Many responders were not familiar with the ESPGHAN/NASPGHAN guideline for functional constipation. Nonetheless, therapeutic decisions correlated fairly well with recommendations from the guideline, especially for children 1 year of age or older. Guideline awareness and adherence remain to be improved. Future studies should focus on exploring strategies to improve guideline implementation through the development of digital learning tools.

Attention Deficit Hyperactivity Disorder and Functional Defecation Disorders in Children.

OBJECTIVES: The aim of the study was to assess the prevalence of attention deficit hyperactivity disorder (ADHD) in children presenting with functional defecation disorders (FDDs) and to assess the prevalence of FDDs in children with ADHD. METHODS: A cross-sectional cohort study was carried out between September 2014 and May 2016. Group 1: Parents of children with FDDs according to the Rome III criteria completed the Child Behavior Checklist and the VvGK (Dutch questionnaire based on the American Disruptive Behavior Disorder rating scale). Patients with ADHD subarea scores ≥70 on the Child Behavior Checklist and/or ≥16 on the VvGK were referred for further psychiatric evaluation. Group 2: Parents of children treated for ADHD at a specialized ADHD outpatient clinic completed a standardized questionnaire regarding their child's defecation pattern. RESULTS: In group 1 (282 children with FDDs), 10.3% (7.1%-13.5% bias-corrected and accelerate confidence interval) were diagnosed with ADHD. Group 2 consisted of 198 children with ADHD, 22.7% (17.6-28.8 bias-corrected and accelerate confidence interval) fulfilled the Rome III criteria for an FDD. Children with both an FDD and ADHD reported urinary incontinence significantly more often compared to children with an FDD or ADHD alone: 57.1% in FDD + ADHD versus 22.8% in FDD alone (P < 0.001) and 31.1% in ADHD + FDD versus 7.8% in ADHD alone (P < 0.001). CONCLUSIONS: Approximately 10.3% of children with FDDs had ADHD and 22.7% of children with a known diagnosis of ADHD fulfilled the Rome III criteria for an FDD. This observation suggests that screening for behavioral disorders and FDDs should be incorporated into the diagnostic workup of these groups of children.

Transanal Irrigation in the Treatment of Children With Intractable Functional Constipation.

OBJECTIVES: The aim of the study was to assess the treatment efficacy of transanal irrigation and parental satisfaction in children with intractable functional constipation (FC) treated with Peristeen. METHODS: Cross-sectional survey study among parents of children (age 0-18 years) treated with Peristeen for FC (based on the Rome III criteria). Anonymous questionnaires were sent out to parents via mail, these consisted of 25 self-developed, multiple-choice questions regarding the use of Peristeen, current gastrointestinal symptoms, adverse effects of Peristeen, concomitant medication use, and parental satisfaction. RESULTS: Out of 91 invited families, 67 (74%) returned the questionnaire. In total, 84% of patients experienced fecal incontinence prior to treatment. Out of all children who still used Peristeen at the time of survey (n = 49), fecal incontinence had resolved completely in 41%, 12% experienced occasional episodes of fecal incontinence (<1 episode per week) and the remaining 47% still experienced episodes of fecal incontinence regularly (≥1 time per week). A total of 28 children (42%) experienced pain during rectal irrigation, especially during insertion of the catheter, inflating the balloon, or during irrigation. Overall, 86% of the parents were satisfied with the result of transanal irrigation and 67% reported that they would continue using transanal irrigation for the treatment of their child's symptoms. CONCLUSIONS: Transanal irrigation may be effective in the treatment of children with FC and renders a high parental satisfaction. Future prospective studies, preferably RCTs, are necessary to further evaluate this treatment option.

Role of Polyethylene Glycol in the Treatment of Functional Constipation in Children.

According to international guidelines, polyethylene glycol (PEG) is the laxative of first choice in the treatment of functional constipation in children, both for disimpaction and for maintenance treatment. PEG acts as an osmotic laxative and its efficacy is dose dependent. PEG is highly effective, has a good safety profile, and is well tolerated by children. Only minor adverse events have been reported. Overall the use of PEG in children has been reported to be safe, although in patients predisposed to water and electrolyte imbalances monitoring of serum electrolytes should be considered.

Assessing colonic anatomy normal values based on air contrast enemas in children younger than 6 years.

BACKGROUND: Contrast enemas with barium or water-soluble contrast agents are sometimes performed in children with severe intractable constipation to identify anatomical abnormalities. However there are no clear definitions for normal colonic size or abnormalities such as colonic dilation or sigmoid redundancy in children. OBJECTIVE: To describe characteristics of colonic anatomy on air contrast enemas in children without constipation to provide normal values for colonic size ratios in children. MATERIALS AND METHODS: We performed a retrospective chart review of children aged 0-5 years who had undergone air contrast enemas for intussusception. The primary outcome measures were the ratios of the diameters and lengths of predetermined colonic segments (lengths of rectosigmoid and descending colon; diameters of rectum, sigmoid, descending colon, transverse colon and ascending colon) in relation to the L2 vertebral body width. RESULTS: We included 119 children (median age 2.0 years, range 0-5 years, 68% boys). Colonic segment length ratios did not change significantly with age, although the differences for the rectosigmoid/L2 ratio were borderline significant (P = 0.05). The ratios that involved the rectal and ascending colon diameters increased significantly with age, while diameter ratios involving the other colonic segments did not. Differences by gender and race were not significant. CONCLUSION: These data can be used for reference purposes in young children undergoing contrast studies of the colon.

Using the Bristol Stool Scale and Parental Report of Stool Consistency as Part of the Rome III Criteria for Functional Constipation in Infants and Toddlers.

OBJECTIVES: To evaluate among parents of infants and toddlers the agreement between parental report and the Bristol Stool Scale (BSS) in assessing stool consistency and the effect of both methods on determining the prevalence of functional constipation (FC) according to the Rome III criteria. STUDY DESIGN: Parents of children ≤48 months of age who were seen for a well-child visit completed a questionnaire about their child's bowel habits during the previous month. Cohen kappa coefficient (κ) was used to measure intrarater agreement between parental report of stool consistency ("hard," "normal," "soft/mucous/liquid") and the BSS (types 1-2, hard; types 3-5, normal; types 6-7, loose/liquid). The prevalence of FC was assessed based on the questionnaire according to the Rome III criteria, comparing both methods of stool consistency assessment. RESULTS: Parents of 1095 children (median age, 15 months; range, 1-48) were included. Only fair agreement existed between the 2 methods of stool consistency assessment (κ = 0.335; P < .001). According to the Rome III criteria, using parental report the prevalence of FC was 20.5% and using the BSS the prevalence was 20.9% (P = .87). The agreement between these 2 methods for assessing the prevalence of FC was excellent (κ = 0.95; P < .001). CONCLUSIONS: Only fair agreement exists between the BSS and parental report of stool consistency among parents of infants and toddlers. Different methods of stool consistency assessment did not result in a difference in the prevalence of FC.

Is There an Association between Functional Constipation and Excessive Bodyweight in Children?

OBJECTIVES: To determine the prevalence of functional constipation, overweight, and obesity in a cross-sectional observational study among children in Colombia and to examine the association between functional constipation and excessive bodyweight in this population. STUDY DESIGN: Demographics, anthropometric data, and questionnaires were collected from 2820 children between 8 and 18 years of age across 4 regions in Colombia. A Spanish translation of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version was used to determine the prevalence of functional constipation. Anthropometric measurements of weight, height, and body mass index (BMI) were obtained following World Health Organization guidelines; overweight was defined as a BMI z-score (adjusted for sex and age) between 1 and 2, obesity was defined as a BMI z-score >2. RESULTS: A total of 368 children (13.0%) were found to have functional constipation, 542 children (19.2%) were overweight, and 188 children (6.7%) were obese. Functional constipation did not occur more frequently in children who were obese (14.9%) or overweight (13.1%) compared with children with normal weight (12.9%, P = .73). The prevalence of functional constipation, overweight, and obesity differed significantly between regions. Functional constipation and excessive bodyweight were significantly more common in children attending private schools compared with children attending public schools. CONCLUSIONS: Functional constipation, overweight, and obesity are commonly observed in children in Colombia. No association between functional constipation and overweight or obesity was found.

Is There A Role for Pre-, Pro- and Synbiotics in the Treatment of Functional Constipation in Children? A Systematic Review.

PURPOSE OF REVIEW: To investigate the efficacy and safety of pre-, pro- and synbiotics in the treatment of pediatric functional constipation (FC). RECENT FINDINGS: A recent study reported that the gut microbiota in obese children with FC differs from that of obese children without FC. The gut microbiota may be involved in the pathophysiology of FC. Pre- and probiotics have been suggested as potential treatment modalities for FC in children. SUMMARY: PubMed and Cochrane databases were searched from inception to February 2016. We found 6 RCTs on prebiotics, 6 RCTs on probiotics and 1 RCT concerning synbiotics. Overall, most studies were at high risk of bias. The majority of studies were unable to demonstrate a significant effect of pre-, pro- or synbiotics on predefined outcome measures such as defecation frequency, fecal incontinence and painful or difficult defecation. Pre-, pro- and synbiotics were not associated with significant adverse effects. In conclusion, there is insufficient evidence to recommend pre-, pro- or synbiotics in the treatment of children with functional constipation. High-quality randomized controlled trials are warranted to further explore these treatment modalities.

Prevalence of Functional Gastrointestinal Disorders in Schoolchildren in Ecuador.

The prevalence of functional gastrointestinal disorders (FGIDs) in children in Ecuador is unknown. We describe a survey study in 2 schools in Quito, Ecuador, using a Spanish translation of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-RIII). A total of 417 children (51% boys) with a mean age of 12.0 years were included. FGIDs were present in 95 children (22.8%) and occurred in 25% of girls and in 20.7% of boys (P = 0.296). Functional defecation disorders were found in 12.0% of children, 9.4% had an abdominal pain-related FGID and 3.8% was diagnosed with a vomiting or aerophagia FGID.
