Dysphagia in adults operated on for esophageal atresia--use of a symptom score to evaluate correlated factors

The International Network on Oesophageal Atresia (INoEA) consensus guidelines on the transition of patients with oesophageal atresia-tracheoesophageal fistula

Oesophageal atresia-tracheoesophageal fistula (EA-TEF) is a common congenital digestive disease. Patients with EA-TEF face gastrointestinal, surgical, respiratory, otolaryngological, nutritional, psychological and quality of life issues in childhood, adolescence and adulthood. Although consensus guidelines exist for the management of gastrointestinal, nutritional, surgical and respiratory problems in childhood, a systematic approach to the care of these patients in adolescence, during transition to adulthood and in adulthood is currently lacking. The Transition Working Group of the International Network on Oesophageal Atresia (INoEA) was charged with the task of developing uniform evidence-based guidelines for the management of complications through the transition from adolescence into adulthood. Forty-two questions addressing the diagnosis, treatment and prognosis of gastrointestinal, surgical, respiratory, otolaryngological, nutritional, psychological and quality of life complications that patients with EA-TEF face during adolescence and after the transition to adulthood were formulated. A systematic literature search was performed based on which recommendations were made. All recommendations were discussed and finalized during consensus meetings, and the group members voted on each recommendation. Expert opinion was used when no randomized controlled trials were available to support the recommendation. The list of the 42 statements, all based on expert opinion, was voted on and agreed upon.

The association of feeding difficulties and generic health-related quality of life among children born with esophageal atresia

BACKGROUND

Children born with esophageal atresia experience feeding difficulties. This study investigates the association of feeding difficulties and generic health-related quality of life among children aged 2-7 and 8-17 years, born with esophageal atresia.

METHODS

108 families (n = 36 aged 2-7 years; n = 72 aged 8-17) answered a survey regarding difficulties in their child's mealtimes and a validated generic health-related quality of life instrument(PedsQL 4.0). Clinical data was collected from hospital records. The association of feeding difficulties and health-related quality of life was analysed trough Mann-Whitney U-test. Linear regression determined whether the number of concurrent feeding difficulties in the child decreased the health-related quality of life scores. P < 0.05 was considered significant.

RESULTS

In children aged 2-7 and 8-17 years, to have a gastrostomy, to use a food infusion pump, need for energy-enriched food and eating small portions were respectively significantly associated with lower total health-related quality of life scores in the parent-reports (p < 0.05). Most of the feeding difficulties had a negative significant relationship with the domains of physical and social functioning. Additionally, in the older age group, long mealtimes and adult mealtime supervision were associated with lower scores in both child and parent reports. In both age groups, an increased number of feeding difficulties in the child decreased the total generic health-related quality of life scores (p < 0.01).

CONCLUSION

Specific feeding difficulties are associated with low health-related quality of life among children with esophageal atresia. An increasing number of feeding difficulties is associated to decreasing health-related quality of life-scores. Further research is needed to understand these associations.

Quality of life after type-A esophageal atresia surgery: changes over time and effect of pre-anastomotic elongation

AIM

To assess mid-/long-term postoperative quality of life (QOL) of esophageal atresia (EA) patients.

METHODS

Modified gastrointestinal quality-of-life index surveys were administered to postoperative EA patients who were at least 7 years old at evaluation to assess three topics about general lifestyle (GL), five topics about EA, and four topics about mental health (MH). For MH, caregivers were also interviewed, but separately. Subjects were divided according to age: children (7-12 years old), teenagers (13-19), and adults (20 and over) and compared according to Foker or Kimura elongation (FK) or bougienage stretching (BS).

RESULTS

There were 22 patients evaluated. Responses for GL, EA, and MH did not differ significantly between age groups, but MH responses by caregivers for subjects who were children or teenagers scored significantly lower than responses they made themselves. For primary esophageal elongation technique (PET), age at esophagoesophagostomy was significantly higher in FK. Despite FK scoring 15.1 versus 12.4 for BS during EA evaluation, this difference was not statistically significant.

CONCLUSION

Changes in QOL responses according to age were unremarkable. However, discrepancies in MH indicate that subjects felt better than their caregivers thought. PET did not appear to influence QOL.

The cause of dysphagia in patients with esophageal atresia: a systematic review and meta-analysis

PURPOSE

Dysphagia is the most common symptom in patients with esophageal atresia (EA) of all ages. There is no study addressing the direct relation between dysphagia and surgical results. Therefore, a systematic review was performed to define the relationship between surgical complications and dysphagia in patients with EA.

METHODS

The systematic review was drafted under PRISMA guidelines. Systematic literature search was performed for the period 2000 (Jan) to 2019 (Dec)-20 years-in the databases: MEDLINE, EMBASE, and PubMed. Statistical analysis was performed using Comprehensive Meta-Analysis Version 3.0 software.

RESULTS

Among 767 articles, 486 abstracts were screened for the inclusion criteria. The full-texts of 64 articles were assessed for eligibility. The sub-group analysis could be performed in 4 articles for anastomotic strictures. Heterogeneity was calculated by I² statistic as 18,487 and pooled odds ratio was measured under the fixed effect model (Q = 3.68; P = 0.298, I² = 18,487). There was no significant relationship with an odds ratio of 1.37 between anastomotic stricture (AS) and dysphagia (95% CI 0.631-2.973, p = 0.426). There was no publication bias for the data (Begg's test, p = 0.496; Egger's tests, p = 0.335).

CONCLUSION

This meta-analysis did not reveal a significant relationship between AS and dysphagia in children with EA. Since many other factors contribute to dysphagia, comprehensive variable information such as detailed standardized registry systems for rare diseases for pooling analysis is needed regarding other potential factors including surgical complications.

Predictors of histopathological esophagitis in infants and adolescents with esophageal atresia within a national follow-up programme

PURPOSE

Esophageal atresia (EA) is a congenital anomaly of the foregut. Although the survival has improved over the years there is a significant gastrointestinal morbidity affecting physical function and health-related quality of life. The aims of the study were to identify and evaluate predictors of histopathological esophagitis in infants and adolescents with EA.

METHODS

Single centre, cross-sectional study including one and 15-year-old patients operated for EA that participated in the national follow-up programme between 2012 and 2020 according to a pre-established protocol including upper endoscopy with oesophageal biopsies and 24h-pH-test. Data was collected from patients' medical records and pH-analysis software. Regression models were used to identify predictors of histopathological oesophagitis. Possible predictors were abnormal reflux index, endoscopic esophagitis, hiatal hernia, symptoms of gastroesophageal reflux (GER) and age.

RESULTS

65 patients were included, 47 children and 18 adolescents. All children were treated with PPI during their first year of life. Symptoms of GER were reported by 13 (31.7%) of the infant's caregivers, 34 of the children (72.3%) had abnormal reflux index and 32 (68.1%) had histopathological esophagitis. The corresponding numbers for adolescents were 8 (50%), 15 (83.3%) and 10 (55.6%). We found no significant associations between histopathological esophagitis and endoscopic esophagitis, symptoms of GER, hiatus hernia or age group. Abnormal reflux index was an independent predictor of histopathological esophagitis. Seven patients with normal reflux index had histopathological esophagitis, all grade I.

CONCLUSIONS

We found a high prevalence of histopathological esophagitis despite PPI treatment in accordance with recommendations. No significant difference between the two age groups was seen. Abnormal reflux index was an independent predictor of histopathological esophagitis. However, we cannot recommend the use of pH-metry as a substitute for esophageal biopsies; future studies are needed to elucidate if esophageal biopsies might be postponed in infants with normal reflux index.

Pulmonary function in children and adolescents after esophageal atresia repair

INTRODUCTION

Respiratory morbidity after esophageal atresia (EA) is common. The aims of this study were to assess pulmonary function, to identify risk factors for pulmonary function impairment (PFI), and to investigate the relations between respiratory morbidity, defined as medical treatment for respiratory symptoms or recent pneumonia and PFI after EA repair.

MATERIAL AND METHODS

Single center retrospective observational study including patients with EA who participated in the follow-up program for 8- or 15-year old patients from 2014 to 2018 and performed pulmonary function testing by body plethysmography, dynamic spirometry, impulse oscillometry, and diffusing capacity of the lungs. Univariate and multiple stepwise logistic regression with PFI as outcome were performed. Anastomotic leak, episodes of general anesthesia, extubation day, birth weight, age at follow up, gross classification, and abnormal reflux index were independent variables.

RESULTS

In total, 47 patients were included. PFI was found in 19 patients (41%) and 16 out of 19 patients (84%) had an obstructive pattern. Respiratory morbidity was found in 23 (52%, NA = 3) of the patients with no correlation to PFI. Birth weight, age at follow-up, and episodes of general anesthesia were identified as risk factors for PFI.

CONCLUSION

Respiratory morbidity and PFI were common in children and adolescents after EA repair. The major component of PFI was obstruction of the airways. The risk for PFI increased with lower birth weight and older age at follow up. The poor correlation between respiratory morbidity and PFI motivates the need of clinical follow up including pulmonary function tests.

Quality of life assessment in esophageal atresia patients: a systematic review focusing on long-gap esophageal atresia

BACKGROUND

Children born with esophageal atresia (EA) have inherent abnormalities in esophageal motility which may impact upon patient and family Quality of Life (QoL). Currently, paucity of data exists for long-term outcomes of long-gap EA. We aimed to: (1) summarize QoL tools reported in the literature, focusing upon studies involving long-gap EA patients, and (2) compare QoL for long-gap versus non-long-gap EA patients.

METHOD

We performed a systematic review of Cochrane Register of Controlled Trials, PubMed, EMBASE, and Ovid databases (January 1980-May 2018) in accordance with the PRISMA protocol.

RESULT

Six studies were identified (536 patients total), and 419/536 (78%) patients completed QoL assessment. Response rates ranged from 29% to 100%. Median study size was 86 (range 8-159). Esophageal atresia type was described in 477 patients, and 74/477 (16%) were long-gap. Common assessment tools were Gastrointestinal Quality of Life Index and 36-Item Short-Form Health Survey. Compared with healthy individuals, long-gap EA patients suffered more gastrointestinal symptoms. There were no significant differences in QoL outcomes between long-gap and non-long-gap EA patients.

CONCLUSION

Current literature suggests no significant difference in QoL outcomes between long-gap and non-long-gap EA patients. However, due to questionnaire variability and range of response rates, the data should be interpreted with care.

LEVEL OF EVIDENCE

Level II.

ESPGHAN-NASPGHAN Guidelines for the Evaluation and Treatment of Gastrointestinal and Nutritional Complications in Children With Esophageal Atresia-Tracheoesophageal Fistula

BACKGROUND

Esophageal atresia (EA) is one of the most common congenital digestive anomalies. With improvements in surgical techniques and intensive care treatments, the focus of care of these patients has shifted from mortality to morbidity and quality-of-life issues. These children face gastrointestinal (GI) problems not only in early childhood but also through adolescence and adulthood. There is, however, currently a lack of a systematic approach to the care of these patients. The GI working group of International Network on Esophageal Atresia comprises members from ESPGHAN/NASPGHAN and was charged with the task of developing uniform evidence-based guidelines for the management of GI complications in children with EA.

METHODS

Thirty-six clinical questions addressing the diagnosis, treatment, and prognosis of the common GI complications in patients with EA were formulated. Questions on the diagnosis, and treatment of gastroesophageal reflux, management of "cyanotic spells," etiology, investigation and management of dysphagia, feeding difficulties, anastomotic strictures, congenital esophageal stenosis in EA patients were addressed. The importance of excluding eosinophilic esophagitis and associated GI anomalies in symptomatic patients with EA is discussed as is the quality of life of these patients and the importance of a systematic transition of care to adulthood. A systematic literature search was performed from inception to March 2014 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Clinical Trials, and PsychInfo databases. The approach of the Grading of Recommendations Assessment, Development and Evaluation was applied to evaluate outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation, using the nominal voting technique. Expert opinion was used where no randomized controlled trials were available to support the recommendation.

Dysphagia in children with repaired oesophageal atresia

Dysphagia is a common problem in children with repaired oesophageal atresia (OA). Abnormalities in the oropharyngeal and oesophageal phase have hardly been studied. The aims of this study were to assess the prevalence of dysphagia in children with repaired OA and to identify and differentiate oral and pharyngeal dysphagia based on videofluoroscopic swallow study (VFSS) findings in a limited number of children in this cohort. Medical records of 111 patients, born between January 1996 and July 2013 and treated at the Radboudumc Amalia Children's Hospital, were retrospectively reviewed. The prevalence of dysphagia was determined by the objective and modified Functional Oral Intake Scale (FOIS) in four age groups. The first performed VFSS of 12 children was structurally assessed. The prevalence of dysphagia was 61 of 111 patients (55 %) in age group <1 year. In age group 1-4, 5-11 and 12-18 years, the prevalence of dysphagia decreased from 54 of 106 (51 %) patients to 11 of 64 (17 %) and 5 of 24 (21 %) patients. The 12 VFSS's reviews revealed oral dysphagia in 36 % and pharyngeal dysphagia in 75 %.

CONCLUSIONS

This study highlights dysphagia as an important problem in different age groups of children with repaired OA. Furthermore, our study shows the presence of oropharyngeal dysphagia in this population. This study emphasizes the need to standardize the use of objective dysphagia scales, like the modified FOIS, to provide a careful follow-up of children with repaired OA.

WHAT IS KNOWN

• Prevalence of dysphagia in children with repaired oesophageal atresia varies widely (ranges from 45 to 70 %) in literature. • Oral, pharyngeal and oesophageal dysphagia require different treatment approaches. What is New: • We determined dysphagia based on functional oral intake and provide an overview of change in dysphagia prevalence and severity over time in children with repaired OA. • Our study shows that dysphagia, including oropharyngeal dysphagia, is highly prevalent in young children with repaired OA and improves with time.

The evaluation of deglutition with videofluoroscopy after repair of esophageal atresia and/or tracheoesophageal fistula

AIM

A retrospective study was performed to evaluate the functional disorders of deglutition with videofluoroscopy (VFS), in children operated for esophageal atresia (EA) and/or tracheoesophageal fistula (TEF).

METHODS

Patients with the repair of EA-TEF were evaluated in respect to the type of malformation, operative procedure, postoperative complications, deglutitive and respiratory symptoms, and gastroesophageal reflux disease (GERD). The dysphagia score, VFS findings of oral, pharyngeal and esophageal phases, and penetration-aspiration scale (PAS) score were recorded in the evaluation of the deglutitive functions.

RESULTS

Thirty-two cases with a median age of 48months (2-120months), and male to female ratio of 14:18 were included in the study. Most of the cases had Gross type C anomaly (n=26, 81.3%), and the others were type A (n=3), D (n=2) and E (n=1). The incidence of associated anomalies was 71.8%. The patients underwent primary (n=26, 81.3%) or delayed (n=6, 18.7%) anastomosis. Postoperative complications including anastomotic stricture (n=12), leak (n=2) and recurrent fistula (n=2) were managed by dilatation, conservative approach and repair of the fistula, respectively. Recurrent pneumonia (n=13), cough with liquid intake (n=10) and food impaction (n=7) were recorded in the history. Management of GERD included medical (n=11) and surgical (n=7) treatment. The median dysphagia score was 3.5 (min: 0-max: 27). The oral phase of VFS was normal in most of the cases (n=29, 90.6%). Only three had mild or moderate impairment, and none had severe. The pharyngeal phase showed no impairment in 23 of the cases (71.8%), and severe impairment was observed only in 3 of all, for the parameters of hyolaryngeal elevation and airway closure. Opposite to the first two phases of the deglutition, the esophageal phase was normal in only 2 of the cases (6.3%). Among the other 30 cases with impairment, only two had mild, and the rest had moderate to severe problems. Esophageal backflow, motility and residue were the most severely impaired parameters of this phase. The PAS evaluation revealed no penetration and aspiration in 26 of the cases (81.3%), while 1 had penetration and five had aspiration.

CONCLUSION

The patients with repaired EA-TEF may reveal deglutitive and respiratory symptoms in follow-up, necessitating certain investigations. The deglutition is functionally evaluated with VFS. While the disorders of oral and pharyngeal phases are less frequent and prominent, the esophageal phase reveals disorders with higher incidence and severity.

Health-related quality of life among children, young people and adults with esophageal atresia: a review of the literature and recommendations for future research

PURPOSE

Esophageal atresia (EA) is a rare congenital malformation requisite of surgical treatment. Survival rates have significantly increased in recent decades, but treated children are at risk of chronic morbidity. This study aims to review the literature on health-related quality of life (HRQOL) in patients with EA and describe the questionnaires used.

METHODS

A literature search was conducted in Pubmed, Cinahl and PsycINFO, from inception to January 2015. A meta-analysis of studies investigating HRQOL in patients with EA compared to healthy references was performed. The effect size was calculated as Cohen's d.

RESULTS

Twelve articles (published 1995-2014) describing HRQOL among children, young people and adults were identified. Only European studies were found, and these had variable sample sizes (8-128). Overall HRQOL was reported to be reduced in five of the seven studies that compared overall HRQOL with a healthy reference population. Impaired physical or general health was described in eight articles. In the meta-analysis, eight eligible studies provided 16 estimates of the effect of EA, six of which reached statistical significance for worse HRQOL (p < 0.05). Using Cohen's criteria, the pooled estimate of the effect of EA was small for overall and physical HRQOL, and <0.2 for the mental and social HRQOL components. Altogether, 15 different questionnaires were used, and none were condition specific for EA.

CONCLUSIONS

Different findings are reported; however, this study suggests that patients with EA may have a reduced HRQOL. Moreover, HRQOL is not adequately measured in this group. Additional research is required.

Impaired peripheral airway function in adults following repair of esophageal atresia

BACKGROUND

Esophageal atresia (EA) often leads to persistent symptoms and impaired respiratory function in adulthood. The role of peripheral airways in this impairment has not been previously investigated. Furthermore, asthma-like symptoms are common in these patients.

PURPOSE

The purpose of this study was to investigate pulmonary outcome, including possible peripheral airway dysfunction, perhaps missed by conventional pulmonary function tests and to see if the diagnosis asthma was accurate.

METHODS

Twenty eight patients operated for EA in Gothenburg 1968-1983 answered a questionnaire regarding respiratory symptoms and underwent pulmonary function tests. Peripheral airway function was measured by multiple breath washout.

RESULTS

22/28 (79%) patients had a history of respiratory symptoms. Abnormal peripheral airway function was found in 17 (61%) patients, while only 6 (21%) patients displayed values indicating central obstruction. Nine patients had restrictive disease. Airway hyperresponsiveness was frequent and associated with atopy and airway inflammation. However, respiratory symptoms or doctor-diagnosed asthma did not correlate with any specific lung function test abnormality.

CONCLUSION

Different lung function abnormalities are present in EA survivors, and peripheral airway disease is common. Classical asthma seems to be difficult to diagnose in this patient group. Given the high prevalence of respiratory morbidity, long-term follow-up of pulmonary function, including peripheral airway function, is warranted.

Long-term health-related quality of life after complex and/or complicated esophageal atresia in adults and children registered in a German patient support group

BACKGROUND

Health-related quality of life (HRQoL) after esophageal atresia (EA) repair is postulated to be good. However, little is known about the long-term results after repair of complex and/or complicated EA regarding HRQoL. We investigated long-term HRQoL after delayed anastomosis, esophageal replacement, major revisions, or multiple dilatations in patients registered in a support group.

METHODS

Patients registered in the German patient support group database (KEKS) were enrolled and allocated to subgroups according to surgical treatment and age. HRQoL was evaluated using validated questionnaires (GIQLI, WHO-5, KIDSCREEN27).

RESULTS

Complete follow-up (mean 14.5 ± 9.8 years) was available for 90/92 patients. Patients were allocated to subgroups delayed anastomosis (n=28), esophageal replacement (n=27), major revisions (n=15), and multiple dilatations (n=20). Adult patients presented with impaired well-being according to WHO-score and gastrointestinal function (GIQLI). In contrast, HRQoL of children was comparable to controls in most KIDSCREEN27-dimensions. Delayed anastomosis was associated with most-favourable HRQoL. Regarding physical well-being, these children scored significantly better than controls [64.01 ± 10.40 vs. 52.36 ± 8.73;p=0.0011], children after replacement [51.40 ± 5.70;p=0.008], revisions [52.04 ± 6.97;p=0.026], and multiple dilatations [50.22 ± 9.67,p=0.04].

CONCLUSIONS

HRQoL after complex and/or complicated EA is excellent in children registered in a patient support group. In adults, disease-specific symptoms negatively affect HRQoL. Our data indicate that saving the esophagus may achieve the best HRQoL.

Esophageal atresia: long-term morbidities in adolescence and adulthood

Survival rates in esophageal atresia (EA) patients have reached 90%. In long-term follow-up studies the focus has shifted from purely surgical or gastrointestinal evaluation to a multidisciplinary approach. We evaluated the long-term morbidity in adolescent and adult EA patients and discussed mainly nonsurgical issues. Dysphagia is common and reported in up to 85% of patients. In young adults gastroesophageal reflux disease occurs frequently with development of Barrett esophagus in 6% reported in different series. It is difficult to estimate respiratory morbidity from the literature because many different definitions, questionnaires, and study designs have been used. However, many patients seem to suffer from respiratory problems even into adulthood. In conclusion, morbidity is not only restricted to surgical problems but many different domains are involved. These are all related and together determine to a large extent the quality of life of EA patients and also of their families. We assume that a multidisciplinary care approach seems best to address their special needs.

Long-term respiratory symptoms following oesophageal atresia

Background

Oesophageal atresia (OA) is a congenital malformation that can lead to persistent respiratory symptoms in adulthood.

Aim

To describe the prevalence of respiratory symptoms in adulthood in a population-based study of patients with repaired OA and to compare this with the prevalence in the general population.

Methods

Of 80 patients operated for OA in Gothenburg in 1968–1983, 79 were located. The patients received a questionnaire on respiratory symptoms. Controls were 4979 gender- and age-matched subjects who answered the same questions.

Results

The questionnaire was answered by 73 of 79 (92%) patients. Physician-diagnosed asthma was reported by 30% in the OA group vs 10% in the control group (OR 4.1; 95% CI 2.4–6.8), and recurrent wheeze in 29% vs 5.5% (OR 6.9; 4.1–11.6). Also wheeze during the last year, asthma medication, a long-standing cough, cough with sputum production and chronic bronchitis were significantly more common among the patients with OA. In contrast, there was no significant difference regarding risk factors for asthma. The prevalence of respiratory symptoms did not appear to decrease with age.

Conclusion

A high prevalence of respiratory symptoms remains among adult patients with repaired OA. Many of the patients had an asthma diagnosis. However, asthma heredity or allergic rhinitis was not overrepresented.
