Congenital diaphragmatic hernia (CDH) is a life-threatening anomaly with a mortality rate of approximately 40-50%, depending on case selection. It has been suggested that new therapeutic modalities such as nitric oxide (NO), high frequency oxygenation (HFO) and extracorporal membrane oxygenation (ECMO) might decrease mortality associated with pulmonary hypertension and the sequelae of artificial ventilation. When these new therapies indeed prove to be beneficial, a larger number of children with severe forms of CDH might survive, resulting in an increase of CDH-associated complications and/or consequences. In follow-up studies of infants born with CDH, many complications including pulmonary damage, cardiovascular disease, gastro-intestinal disease, failure to thrive, neurocognitive defects and musculoskeletal abnormalities have been described. Long-term pulmonary morbidity in CDH consists of obstructive and restrictive lung function impairments due to altered lung structure and prolonged ventilatory support. CDH has also been associated with persistent pulmonary vascular abnormalities, resulting in pulmonary hypertension in the neonatal period.
Objective: To assess psychological and social functioning and health related quality of life and its early determinants in children born with congenital diaphragmatic hernia (CDH). Design: Cross-sectional follow-up study. Results: Normal mean (SD) total IQ (100.0 (13.2)) and normal visual-motor integration, but significantly lower results for sustained attention (Bourdon-Vos test, 38.8 (11.2) points) were found. Learning difficulties were reported by 30% of parents. Eight children had scores in the clinical range on the CBCL and/or TRF, indicating clinically significant behavioural problems. Except for the CHQ scale General Health, health status was not different from the reference population. No significant correlations between test results and severity of CDH were found, except for an association of general health and physical functioning with length of hospital stay. Conclusion: CDH patients are at risk for subtle cognitive and behavioural problems, probably not related to CDH severity. Perception of general health is reduced compared to the reference population, indicating that CDH survivors and their parents believe their health is poor and likely to get worse.Congenital diaphragmatic hernia (CDH) is a life threatening anomaly with a mortality rate ranging from 10% to 50%, depending on case selection.
Congenital diaphragmatic hernia (CDH) is associated with pulmonary hypoplasia and pulmonary hypertension. The objective of this study was to assess pulmonary function and exercise capacity and its early determinants in children and adolescents born with high-risk CDH (CDH-associated respiratory distress within the first 24 h) and to explore the relationship of these findings with CDH severity.Of 159 patients born with high-risk CDH, 84 survived. Of the 69 eligible patients, 53 children (mean¡SD age 11.9¡3.5 yrs) underwent spirometry, lung volume measurements and maximal cardiopulmonary exercise testing (CPET). Results of the pulmonary function tests were compared with those from a healthy control group matched for sex, age and height.CDH survivors had a significantly lower forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, maximum mid-expiratory flow and peak expiratory flow when compared with healthy controls. The residual volume/total lung capacity ratio was significantly higher. Linear regression analysis showed that gastro-oesophageal reflux disease was an independent determinant of reduced FEV1 and FVC. CPET results were normal in those tested.High-risk CDH survivors have mild to moderate pulmonary function abnormalities when compared with a healthy matched control group, which may be related to gastro-oesophageal reflux disease in early life. Exercise capacity and gas exchange parameters were normal in those tested, indicating that the majority of patients do not have physical impairment.
BackgroundLong‐term impairment of pulmonary function in trachea‐esophageal fistula (TEF) patients is, at least in part, commonly ascribed to gastro‐esophageal reflux disease (GERD). The objective of this study was to examine the independent effects of the underlying condition and GERD on cardiopulmonary function.MethodsCardiopulmonary function of TEF patients, who had (severe) GERD (s‐GERD) requiring antireflux surgery (TEF + GERD, n = 11) and TEF patients who did not have s‐GERD (group TEF–GERD, n = 20) were compared with control patients who had isolated s‐GERD requiring antireflux surgery (group GERD, n = 13). All patients performed spirometry, lung volume measurements, measurement of diffusion capacity and maximal cardiopulmonary exercise testing (CPET).ResultsMean age of the participants was 13.8 ± 2.7 (group TEF + GERD). 13.2 ± 2.9 (group TEF–GERD), and 14.7 ± 1.5 years (group GERD). FVC and TLC were significantly lower in patients with TEF (with and without s‐GERD) when compared to patients with isolated s‐GERD. Most pulmonary function parameters were similarly affected in both TEF groups, but FEV1 was lower in the TEF + GERD group than in the TEF–GERD group. Cardiopulmonary exercise parameters were similar in all groups.ConclusionsTEF patients had restrictive lung function impairment when compared to patients with isolated s‐GERD. This difference may be due to several causes, including thoracotomy. FEV1 was lower in TEF + GERD when compared to TEF–GERD indicating that GERD may affect large airway function in TEF patients. Other differences between TEF patients with and without s‐GERD were not significant, suggesting only a minor role for GERD. Pediatr Pulmonol. 2011; 46:348–355. © 2010 Wiley‐Liss, Inc.
In this first study describing health-related quality of life in children and adolescents born with oesophageal atresia, we demonstrated that general health remains impaired because of a high incidence of concomitant anomalies and gastrointestinal symptoms in patients with oesophageal atresia when compared with the healthy reference population.
Early GERD is more common in CDH patients with patch closure or intrathoracic position of the stomach. Predictive factors for late GERD could not be identified and screening for early GERD does not protect for future GERD; therefore, long-term follow-up for GERD in CDH survivors is mandatory.
Congenital diaphragmatic hernia (CDH) is accompanied by pulmonary hypoplasia and structural abnormalities of the pulmonary vascular bed. It is unknown whether pulmonary function, exercise capacity, and gas exchange during exercise are impaired in adult CDH survivors. The objective of this study was to assess the long-term pulmonary function, exercise capacity, and gas exchange during exercise and relate these findings with quality of life. Of the 23 patients eligible for this study, 12 adult CDH survivors (mean age, 24.3 +/- 4.1 years) with high-risk CDH agreed to participate. Pulmonary function tests, diffusion capacity, and a cardiopulmonary exercise test (CPET) were performed. The FEV1 (mean z-score +/- SD; -1.30 +/- 1.37), FEF25-75% (-1.49 +/- 1.14), and the KCO (-1.03 +/- 1.24) were found to be lower in CDH survivors. The RV/TLC ratio (28.2% +/- 5.0%) was found to be higher. Despite these abnormalities, percent predicted work load (102% +/- 17.2%) and percent predicted maximal oxygen uptake (90.8% +/- 18.9%) were normal in most of the patients. The quality of life of CDH survivors, assessed with the SF-36 questionnaire, is comparable to the general population. Comparison of participants to non-participants did not reveal significant differences in clinical characteristics. In this first study assessing pulmonary function in adult survivors of CDH, mild airway obstruction was observed in most of the patients together with a slightly reduced diffusion capacity for CO. Exercise capacity and gas exchange parameters were normal in this group, indicating that patients do not have a physical impairment, as reflected by a normal quality of life of CDH patients.
A 16-year-old girl presented with signs of proximal intestinal obstruction. In the neonatal period, surgical correction of an apple peel atresia had been performed, and she also had a situs inversus abdominalis. Revision of the anastomosis had been done when she was 3 years old. Contrast studies apparently again showed a stricture of the anastomosis, which was treated by stricturoplasty. Because of persistent obstruction, reexploration was done and revealed a duodenal membrane. Anastomotic strictures are very rare several years after the primary operation, so other causes of obstruction should be sought.
