Multivariate logistic regression analysis of risk factors for birth defects: a study from population-based surveillance data

OBJECTIVE

To explore risk factors for birth defects (including a broad range of specific defects).

METHODS

Data were derived from the Population-based Birth Defects Surveillance System in Hunan Province, China, 2014-2020. The surveillance population included all live births, stillbirths, infant deaths, and legal termination of pregnancy between 28 weeks gestation and 42 days postpartum. The prevalence of birth defects (number of birth defects per 1000 infants) and its 95% confidence interval (CI) were calculated. Multivariate logistic regression analysis (method: Forward, Wald, α = 0.05) and adjusted odds ratios (ORs) were used to identify risk factors for birth defects. We used the presence or absence of birth defects (or specific defects) as the dependent variable, and eight variables (sex, residence, number of births, paternal age, maternal age, number of pregnancies, parity, and maternal household registration) were entered as independent variables in multivariate logistic regression analysis.

RESULTS

Our study included 143,118 infants, and 2984 birth defects were identified, with a prevalence of 20.85% (95%CI: 20.10-21.60). Multivariate logistic regression analyses showed that seven variables (except for parity) were associated with birth defects (or specific defects). There were five factors associated with the overall birth defects. The risk factors included males (OR = 1.49, 95%CI: 1.39-1.61), multiple births (OR = 1.44, 95%CI: 1.18-1.76), paternal age < 20 (OR = 2.20, 95%CI: 1.19-4.09) or 20-24 (OR = 1.66, 95%CI: 1.42-1.94), maternal age 30-34 (OR = 1.16, 95%CI: 1.04-1.29) or > = 35 (OR = 1.56, 95%CI: 1.33-1.81), and maternal non-local household registration (OR = 2.96, 95%CI: 2.39-3.67). Some factors were associated with the specific defects. Males were risk factors for congenital metabolic disorders (OR = 3.86, 95%CI: 3.15-4.72), congenital limb defects (OR = 1.34, 95%CI: 1.14-1.58), and congenital kidney and urinary defects (OR = 2.35, 95%CI: 1.65-3.34). Rural areas were risk factors for congenital metabolic disorders (OR = 1.21, 95%CI: 1.01-1.44). Multiple births were risk factors for congenital heart defects (OR = 2.09, 95%CI: 1.55-2.82), congenital kidney and urinary defects (OR = 2.14, 95%CI: 1.05-4.37), and cleft lip and/or palate (OR = 2.85, 95%CI: 1.32-6.15). Paternal age < 20 was the risk factor for congenital limb defects (OR = 3.27, 95%CI: 1.10-9.71), 20-24 was the risk factor for congenital heart defects (OR = 1.64, 95%CI: 1.24-2.17), congenital metabolic disorders (OR = 1.56, 95%CI: 1.11-2.21), congenital limb defects (OR = 1.61, 95%CI: 1.14-2.29), and congenital ear defects (OR = 2.13, 95%CI: 1.17-3.89). Maternal age < 20 was the risk factor for cleft lip and/or palate (OR = 3.14, 95%CI: 1.24-7.95), 30-34 was the risk factor for congenital limb defects (OR = 1.37, 95%CI: 1.09-1.73), >=35 was the risk factor for congenital heart defects (OR = 1.51, 95%CI: 1.14-1.99), congenital limb defects (OR = 1.98, 95%CI: 1.41-2.78), and congenital ear defects (OR = 1.82, 95%CI: 1.06-3.10). Number of pregnancies = 2 was the risk factor for congenital nervous system defects (OR = 2.27, 95%CI: 1.19-4.32), >=4 was the risk factor for chromosomal abnormalities (OR = 2.03, 95%CI: 1.06-3.88) and congenital nervous system defects (OR = 3.03, 95%CI: 1.23-7.47). Maternal non-local household registration was the risk factor for congenital heart defects (OR = 3.57, 95%CI: 2.54-5.03), congenital metabolic disorders (OR = 1.89, 95%CI: 1.06-3.37), congenital limb defects (OR = 2.94, 95%CI: 1.86-4.66), and congenital ear defects (OR = 3.26, 95%CI: 1.60-6.65).

CONCLUSION

In summary, several risk factors were associated with birth defects (including a broad range of specific defects). One risk factor may be associated with several defects, and one defect may be associated with several risk factors. Future studies should examine the mechanisms. Our findings have significant public health implications as some factors are modifiable or avoidable, such as promoting childbirths at the appropriate age, improving the medical and socio-economic conditions of non-local household registration residents, and devoting more resources to some specific defects in high-risk groups, which may help reducing birth defects in China.

Endoscopic Chemocauterization with Trichloroacetic Acid for Congenital or Recurrent Tracheoesophageal Fistula in Children with Esophageal Atresia: Experience from a Tertiary Center

BACKGROUND

Recurrent tracheoesophageal fistula (rTEF) is a well-known complication after surgery of EA, occurring in roughly 3-10% of the patients. Recent studies have highlighted safety and efficacy of endoscopic management of recurrent TEF. The aim of this study was to evaluate the efficacy of chemocauterization with trichloroacetic acid (TCA) in rTEF and congenital tracheoesophageal fistula (cTEF).

METHODS

Retrospective chart review of consecutive patients with recurrent or congenital TEF who underwent endoscopic chemo-cauterization between 2018 and 2022 at a tertiary center. Children diagnosed with TEF who underwent primary or secondary endoscopic treatment were included. Median follow up time was 19 months for rTEF and 33 months for cTEF.

RESULTS

During the study period, 18 patients were treated endoscopically by chemocatuerization with TCA at our institution. Treatment of recurrent TEF was successful in 13 of 14 patients (93%) Treatment of congenital TEF was successful in 2 of 4 patients (50%). In 14 patients, closure was seen after 1-2 treatments. There were no serious adverse reactions or complications to the endoscopic treatment of TEF.

CONCLUSION

Endoscopic chemocauterization is a minimal invasive technique with low morbidity and high success rate and may be considered as primary treatment for recurrent TEF.

Simultaneous type III congenital esophageal atresia and patent ductus arteriosus in a low-weight patient: A case report

BACKGROUND

We report a low-birth-weight child (1.8 kg) with neonatal type III congenital esophageal atresia (CEA) combined with symptomatic patent ductus arteriosus (PDA). After comprehensive evaluation, esophageal anastomosis was performed on postnatal day 11 after excluding surgical contraindications, and arterial catheter ligation was performed at the same time. Concurrent surgery for CEA combined with PDA has not been clearly reported in the literature.

CASE SUMMARY

We report a 6-day-old female child with type III CEA and PDA. The patient presented with foam at the mouth after birth, cough and shortness of breath after feeding. At another hospital, she was considered to have neonatal pneumonia, neonatal jaundice and congenital heart disease and transferred to our hospital. After iodine oil radiography of the esophagus and echocardiography we confirmed diagnosis of CEA and PDA. The diameter of the PDA was 8 mm, with obvious left to right shunting. We performed right rear extrapleural orificium fistula ligation and esophageal anastomosis, and ligation of PDA via left axilla straight incision after 5 d of hospitalization. The operations were successful, and the incision healed after 12 d, and the patient was discharged. We re-examined the patient 1 mo after surgery. She did not vomit when she ate rice flour. Esophageal angiography showed no stricture of the anastomotic stoma. The patient weighed 3.2 kg.

CONCLUSION

For CEA patients with multiple risk factors, comprehensive, timely and accurate diagnosis and evaluation, and early treatment may improve prognosis.

Multidisciplinary coordination of care for children with esophageal atresia and tracheoesophageal fistula

Esophageal Atresia/Tracheoesophageal Atresia (EA/TEF) is a multisystem congenital anomaly. Historically, children with EA/TEF lack coordinated care. A multidisciplinary clinic was established in 2005 to provide coordinated care and improve access to outpatient care. This single-center retrospective cohort study was conducted to describe our cohort of patients with EA/TEF born between March 2005 and March 2011, assess coordination of care, and to compare outcomes of children in the multidisciplinary clinic to the previous cohort without a multi-disciplinary clinic. A chart review identified demographics, hospitalizations, emergency visits, clinic visits, and coordination of outpatient care. Twenty-seven patients were included; 75.9% had a C-type EA/TEF. Clinics provided multidisciplinary care and compliance with the visit schedule was high with a median of 100% (IQR 50). Compared to the earlier cohort, the new cohort (N = 27) had fewer hospital admissions and LOS was reduced significantly in the first 2 years of life. Multidisciplinary care clinics for medically complex children can improve coordination of visits with multiple health care providers and may contribute to reduced use of acute care services.

Successful management of oesophageal atresia in Cameroon, Sub-Saharan Africa

Background

Oesophageal atresia (EA) is the most common congenital anomaly of the oesophagus. Despite improvement of survival observed over the previous two decades in developed countries, the mortality remains very high and the management greatly challenging in resource-poor settings such as Cameroon. We report our experience of management of EA in this environment, with a successful outcome.

Materials and Methods

We prospectively assessed patients diagnosed with EA and operated in January 2019, at the University Hospital Centre of Yaounde. Records were reviewed for demographics, history and physical examinations, radiological findings, surgical procedures and outcomes. The study has received approval from the Institutional Ethics Committees.

Results

In total, six patients (three males and three females, sex ratio, 0.5; mean age at diagnosis, 3.6 days; range, 1-7 days) were assessed. A past history of polyhydramnios was found in one patient (16.7%). All patients were classified Waterston Group A at diagnosis, with Ladd-Swenson type III atresia. Early primary repair was performed in four patients (66.7%) and delayed primary repair in two patients (33.3%). Operative repair mainly involved resection of the fistula, suture of trachea and oesophagus end-to-end anastomosis, followed by interposition of vascularised pleural flap. Patients were followed up 24 months. With one late death, the survival rate was 83.3%.

Conclusion

Improvement has been achieved in the outcomes of neonatal surgery in Africa in the past two decades, but EA-related mortality remains relatively too high. Using simple techniques and available, reproducible equipment can improve survival in resource-poor settings.

Neonatal perioperative resuscitation (NePOR) protocol-An update

Unexpected cardiac arrest in the perioperative period is a devastating complication. Owing to immaturity of organ systems, and presence of congenital malformations, morbidity and mortality are higher in neonates. There is abundant literature about early recognition and management of perioperative adverse events in children, but similar data and guidelines for surgical neonates is lacking. The current neonatal resuscitation guidelines cater to a newborn requiring resuscitation at the time of birth in the delivery room. The concerns in a newborn undergoing transition from intrauterine to extra uterine life is significantly different from a neonate undergoing surgery. This review highlights the causes and factors responsible for peri-arrest situations in neonates in the perioperative period, suggests preoperative surveillance for prevention of these conditions, and finally presents the resuscitation protocol of the surgical neonate. All these are comprehensively proposed as Neonatal Peri-operative Resuscitation (NePOR) protocol.

Endoscopic Management of Congenital Esophageal Defects and Associated Comorbidities

The endoscopist plays a critical role in the management of patients with congenital esophageal defects. This review focuses on esophageal atresia and congenital esophageal strictures and, in particular, the endoscopic management of comorbidities related to these conditions, including anastomotic strictures, tracheoesophageal fistulas, esophageal perforations, and esophagitis surveillance. Practical aspects of endoscopic techniques for stricture management are reviewed including dilation, intralesional steroid injection, stenting, and endoscopic incisional therapy. Endoscopic surveillance for mucosal pathology is essential in this population, as patients are at high risk of esophagitis and its late complications such as Barrett's esophagus.

New insights in the prevalence of scoliosis and musculoskeletal asymmetries in adolescents with esophageal atresia

BACKGROUND

Increased risk of scoliosis and musculoskeletal abnormalities in adolescents with esophageal atresia (EA) is reported, but the impact of these abnormalities on physical fitness and motor skills are not known.

METHODS

Scoliosis was assessed radiographically and shoulder and chest abnormalities by a standardized protocol. Physical fitness was evaluated with Grippit, Six-minute walk test, and International Physical Activity Questionnaire and motor skills by Motor Assessment Battery for Children.

RESULTS

Sixty-seven EA adolescents median 16 (13-20) years participated. The prevalence of significant scoliosis (≥ 20º) was 12% (8/67) whereas 22% (15/67) had mild scoliosis (10-19º). Vertebral anomalies occurred in 18/67 (27%), eight of them (44%) had scoliosis. The majority of adolescents (15/23) with scoliosis did not have vertebral anomalies. Musculoskeletal abnormalities were detected in 22-78%. Balance problems occurred three times more frequently than expected (44% vs. 15%, p = 0.004). Submaximal exercise capacity was significantly reduced compared to reference values (p < 0.001). Scoliosis ≥ 20º was related to reduced physical activity (p = 0.008), and musculoskeletal abnormalities to reduced physical activity and impaired motor skills (p = 0.042 and p < 0.038, respectively).

CONCLUSIONS

Significant scoliosis was diagnosed in 12% of the EA adolescents and related to reduced physical activity. Musculoskeletal abnormalities identified in more than half of the patients, were related to reduced physical activity and impaired motor skills, and exercise capacity was significantly below reference group. EA patients with and without vertebral anomalies need health-promoting guidance to prevent impaired motor skills and consequences of reduced physical activity.

Oesophageal Atresia: Prevalence in the Valencian Region (Spain) and Associated Anomalies

The objective was to determine the prevalence of oesophageal atresia (OA) and describe the characteristics of OA cases diagnosed before the first year of life, born between 2007 and 2019, and residents in the Valencian Region (VR), Spain. Live births (LB), stillbirths (SB), and termination of pregnancy for fetal anomaly (TOPFA) diagnosed with OA were selected from the Congenital Anomalies population-based Registry of VR (RPAC-CV). The prevalence of OA per 10,000 births with 95% confidence interval was calculated, and socio-demographic and clinical variables were analyzed. A total of 146 OA cases were identified. The overall prevalence was 2.4/10,000 births, and prevalence by type of pregnancy ending was 2.3 in LB and 0.03 in both SB and TOPFA. A mortality rate of 0.03/1000 LB was observed. A relationship was found between case mortality and birth weight (p-value < 0.05). OA was primarily diagnosed at birth (58.2%) and 71.2% of the cases were associated with another congenital anomaly, mainly congenital heart defects. Significant variations in the prevalence of OA in the VR were detected throughout the study period. In conclusion, a lower prevalence in SB and TOPFA was identified compared to EUROCAT data. As several studies have identified, an association between OA cases and birth weight was found.

Magnetic Resonance Imaging-Based Evaluation of Anatomy and Outcome Prediction in Infants with Esophageal Atresia

INTRODUCTION

There is currently no validated diagnostic modality to characterize the anatomy and predict outcomes of tracheal esophageal defects, such as esophageal atresia (EA) and tracheal esophageal fistulas (TEFs). We hypothesized that ultra-short echo-time MRI would provide enhanced anatomic information allowing for evaluation of specific EA/TEF anatomy and identification of risk factors that predict outcome in infants with EA/TEF.

METHODS

In this observational study, 11 infants had pre-repair ultra-short echo-time MRI of the chest completed. Esophageal size was measured at the widest point distal to the epiglottis and proximal to the carina. Angle of tracheal deviation was measured by identifying the initial point of deviation and the farthest lateral point proximal to the carina.

RESULTS

Infants without a proximal TEF had a larger proximal esophageal diameter (13.5 ± 5.1 mm vs. 6.8 ± 2.1 mm, p = 0.07) when compared to infants with a proximal TEF. The angle of tracheal deviation in infants without a proximal TEF was larger than infants with a proximal TEF (16.1 ± 6.1° vs. 8.2 ± 5.4°, p = 0.09) and controls (16.1 ± 6.1° vs. 8.0 ± 3.1°, p = 0.005). An increase in the angle of tracheal deviation was positively correlated with duration of post-operative mechanical ventilation (Pearson r = 0.83, p < 0.002) and total duration of post-operative respiratory support (Pearson r = 0.80, p = 0.004).

DISCUSSION

These results demonstrate that infants without a proximal TEF have a larger proximal esophagus and a greater angle of tracheal deviation which is directly correlated with the need for longer post-operative respiratory support. Additionally, these results demonstrate that MRI is a useful tool to assess the anatomy of EA/TEF.

Endoscopic interventional therapies for tracheoesophageal fistulas in children: A systematic review

Methods

An electronic literature search was performed using the keywords "tracheoesophageal fistula," "endoscopic," and "children" in the four major medical databases (Ovid, Embase, PubMed, and Web of Science) right from inception to September 2022. All English language articles describing the endoscopic interventional therapies of TEF in children were reviewed. Two independent researchers screened eligible articles at the title and abstract level. Full texts of potentially relevant articles were then screened again, and reference lists were screened manually to identify additional studies. Relevant data were extracted and analyzed. A synthesis of the relevant data was presented in descriptive form because of the heterogeneity of the included articles. The Chi-Squared test was used with a significance level of 5% (P < 0.05).

Results

Among the 1,167 retrieved papers, a total of 46 studies describing 170 TEF patients with an age range of 0.3-175 months were included, including 11 cases of acquired tracheoesophageal fistula, 144 cases of recurrent tracheoesophageal fistula, and 15 cases of congenital tracheoesophageal fistula (H-type TEF). A total of 119 out of 170 fistulas were successfully blocked via endoscopic techniques with an overall success rate of 70.0%, while 48 fistulas failed to close by endoscopic interventions, following which the procedure was converted to open surgery. No obviously severe intraoperative/postoperative complications occurred during the follow-up period, but only a mild esophageal stricture was noticed in six patients and grade II tracheal stenosis in one patient. Two patients died from causes unrelated to endoscopic procedures, with a mortality rate of approximately 1.2%. A comparative assessment of different endoscopic interventional techniques for TEF that detected endotracheal stenting was performed in six patients and one fistula was successfully blocked (16.7%). De-epithelialization alone was performed in 65 patients and the fistula healed in 47 of them (72.3%), with the mean number of successful treatments required being 2.3 times. Chemical sealant injection was administered in 33 patients and success was achieved in 21 (63.6%). The average requirement for endoscopic procedures was 1.5 times. De-epithelialization, in combination with chemical sealant injection, was performed in 62 patients, achieving the highest success rate of 77.4% (48 patients). Other treatment methods were performed in four patients and successfully treatment outcomes were reported in two of them (50.0%). The mean number of successful treatments required was four times, and a treatment was converted to surgery in one patient (25.0%). An assessment of different TEF types showed that 9 out of 15 congenital TEFs, 7 out of 11 acquired TEFs, and 103 out of 144 recurrent TEFs were successfully occluded. A comparison of the success rate across multiple groups showed a significant difference with a score of P < 0.05, while there was no significant difference in the success rate of different TEF-type groups (P > 0.05).

Conclusion

Endoscopic intervention is currently a preferred treatment modality for children with TEF because of its less-invasive nature, less complications, and high success rate. Among all interventional techniques, de-epithelialization, in combination with chemical sealant, has a higher success rate than other techniques. However, due to the limited number of cases reported for implementing many kinds of techniques, an ideal endoscopic interventional technique has yet to be devised, often necessitating more treatment applications and close follow-up.

Surgical outcome and predictors of neonates with esophageal atresia admitted at Tikur Anbesa Specialized Hospital

BACKGROUND

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus. This anomaly continues to cause considerable morbidity and mortality in Sub-Saharan Africa, presenting various concerns about how to treat esophageal atresia. Esophageal atresia-related neonatal mortality can be reduced by evaluating the surgical outcome and identifying associated factors.

OBJECTIVE

This study aimed to assess the surgical outcome and identify predictors of neonates with esophageal atresia admitted at Tikur Anbesa specialized hospital.

METHODS

Retrospective crossectional study design was employed on 212 neonates with esophageal atresia who were undergone surgical intervention in Tikur Anbesa specialized hospital. Data were entered into epi data 4.6 and exported to Stata version 16 software for further analysis. A logistic regression model with Adjusted odds ratio (AOR), confidence interval (CI) and p-value <0.05 were used to identify predictors of poor surgical outcome of neonates with esophageal atresia.

RESULT

In this study, 25% of newborns who underwent surgical intervention at TikurAbnbesa specialized hospital had successful surgical outcomes, compared to 75% of neonates with esophageal atresia who had poor surgical outcomes. Significant predictors of the poor surgical outcome of neonates with esophageal atresia were severe thrombocytopenia (AOR = 2.81(1.07-7.34)), timing of surgery (AOR = 3.7(1.34-10.1), aspiration pneumonia (AOR = 2.93(1.17-7.38)) and related abnormalities (AOR = 2.26(1.06-4.82)).

CONCLUSION

The results of this study showed that, when compared to other studies, a substantial percentage of newborn children with esophageal atresia had poor surgical outcomes. Early surgical management, aspiration pneumonia and thrombocytopenia prevention and therapy play a big part in improving the surgical prognosis for newborns with esophageal atresia.

Management of Adults With Esophageal Atresia

Esophageal atresia (EA) with or without trachea-esophageal fistula is relatively common congenital malformation with most patients living into adulthood. As a result, care of the adult patient with EA is becoming more common. Although surgical repair has changed EA from a fatal to a livable condition, the residual effects of the anomaly may lead to a lifetime of complications. These include effects related to the underlying deformity such as atonicity of the esophageal segment, fistula recurrence, and esophageal cancer to complications of the surgery including anastomotic stricture, gastroesophageal reflux, and coping with an organ transposition. This review discusses the occurrence and management of these conditions in adulthood and the role of an effective transition from pediatric to adult care to optimize adult care treatment.

Endoscopic versus fluoroscopic esophageal dilatations in children with esophageal strictures: 10-year experience

Esophageal strictures in children may cause dysphagia, choking during feeds, and failure to thrive. They can be treated by balloon dilatations, either under endoscopic or fluoroscopic guidance; there is no literature comparing the methods. Retrospective review of the medical records of children (0-18 years) who were treated with balloon dilatations between 2010 and 2020. The primary outcome was the number of dilatation sessions required until clinical success after 3 months. Secondary outcomes were long-term success at 12 months, and complications of bleeding and perforation. Forty-six patients underwent 174 dilatation sessions. Success rates in the endoscopy and fluoroscopy groups were similar: 62% versus 67% (p = 0.454) at 3 months and 57% versus 67% (p = 0.721) at 12 months. Complication rate was lower in the endoscopy group (0% vs. 15%, p < 0.001). Both endoscopic and radiologic-guided balloon dilatations were shown to be equally effective, but endoscopic guidance had fewer complications.

Tissue Engineering for Gastrointestinal and Genitourinary Tracts

The gastrointestinal and genitourinary tracts share several similarities. Primarily, these tissues are composed of hollow structures lined by an epithelium through which materials need to flow with the help of peristalsis brought by muscle contraction. In the case of the gastrointestinal tract, solid or liquid food must circulate to be digested and absorbed and the waste products eliminated. In the case of the urinary tract, the urine produced by the kidneys must flow to the bladder, where it is stored until its elimination from the body. Finally, in the case of the vagina, it must allow the evacuation of blood during menstruation, accommodate the male sexual organ during coitus, and is the natural way to birth a child. The present review describes the anatomy, pathologies, and treatments of such organs, emphasizing tissue engineering strategies.

Erector spinae plane block for surgery of esophageal atresia in a preterm neonate

Pain management during and after thoracotomy is challenging in premature neonates. Ultrasound-guided fascial plane block techniques, such as the erector spinae plane block are a relatively new regional anesthesia technique and have emerged as an alternative to thoracic epidural due to its clinical effectiveness, ease of administration and theoretically being safer to perform. The relative ease of identifying anatomical landmarks compared to the paravertebral block, as well as its safety profile compared to an epidural, may have contributed to the erector spinae plane Bs growing popularity. Currently, however, the published evidence for the efficacy of regional anesthesia techniques in low birth weight newborns undergoing this surgery is limited to few isolated case reports. Herein we describe the use of unilateral erector spinae plane block as part of anesthesia and postoperative analgesia management of surgical correction of esophageal atresia in a preterm neonate.

Perioperative outcomes in minimally-invasive versus open surgery in infants undergoing repair of congenital anomalies

BACKGROUND

This study compared perioperative outcomes among infants undergoing repair of congenital anomalies using minimally invasive (MIS) versus open surgical approaches.

METHODS

The ACS NSQIP Pediatric (2013-2018) was queried for patients undergoing repair of any of the following 9 congenital anomalies: congenital lung lesion (LL), mediastinal mass (MM), congenital malrotation (CM), anorectal malformation (ARM), Hirschsprung disease (HD), congenital diaphragmatic hernia (CDH), tracheoesophageal fistula (TEF), hepatobiliary anomalies (HB), and intestinal atresia (IA). Inverse probability of treatment weights (IPTW) derived from propensity scores were utilized to estimate risk-adjusted association between surgical approach and 30-day outcomes.

RESULTS

12,871 patients undergoing congenital anomaly repair were included (10,343 open; 2528 MIS). After IPTW, MIS was associated with longer operative time (difference; 95% CI) (16 min; 9-23) and anesthesia time (13 min; 6-21), but less postoperative ventilation days (-1.0 days; -1.4- -0.6) and shorter postoperative length of stay (-1.4 days; -2.4- -0.3). MIS repairs had decreased risk of any surgical complication (risk difference: -6.6%; -9.2- -4.0), including hematologic complications (-7.3%; -8.9- -5.8). There was no significant difference in risk of complication when hematologic complications were excluded (RD -2.3% [-4.7%, 0.1%]). There were no significant differences in the risk of unplanned reoperation (0.4%; -1.5-2.2) or unplanned readmission (0.2%; -1.2-1.5).

CONCLUSIONS

MIS repair of congenital anomalies is associated with improved perioperative outcomes when compared to open. Additional studies are needed to compare long-term functional and disease-specific outcomes.

MINI-ABSTRACT

In this propensity-weighted multi-institutional analysis of nine congenital anomalies, minimally invasive surgical repair was associated with improved 30-day outcomes when compared to open surgical repair.

Isolated distal esophageal atresia in neonates: a case report and review of the literature

Esophageal atresia occurs in 1 out of 2500 to 4500 live births; an isolated variant occurs in 8% of the cases. In this case report and literature review, we present a rare case of isolated distal esophageal atresia happening just 2 cm above the diaphragmatic right leaflet with the connecting band between the two esophageal parts. The location raised the possibility of a direct vascular accident to that segment as a cause of the atresia. Post-operative ambu bagging may facilitate leak at the anastomosis site and should be done carefully, as well as, to introduce contrast with suckling not with jet injection for the same reason. We mentioned that to raise a wariness as this mishap may cause problems.

Advances in Complex Congenital Tracheoesophageal Anomalies

Esophageal atresia with or without tracheoesophageal fistula and tracheobronchomalacia encompass 2 of the most common complex congenital intrathoracic anomalies. Tailoring interventions to address the constellation of problems present in each patient is essential. Due to advances in neonatology, anesthesia, pulmonary, gastroenterology, nutrition and surgery care for patients with complex congenital tracheoesophageal disorders has improved dramatically. Treatment strategies tailored to the individual patient needs are best implimented under the aegis of a comprehensive longitudinal multidisciplinary care team.

Outcome of Newborns with Tracheoesophageal Fistula: An Experience from a Rapidly Developing Country: Room for Improvement

Methods

This is a retrospective review of the medical electronic charts of patients with TEF that were followed at Sidra Medicine in the state of Qatar. The review included the patients who were operated upon in the period of 2011-2021 but continued to follow at our institution in the period of 2018-2021. Demographic data, associated anomalies, preoperative, operative, and postoperative courses, and growth parameters were collected.

Results

A total of 35 patients with TEF (24 males and 11 females) were collected. 49% were full term. We identified seven patients (20%) with isolated TEF, TEF with VACTERL association in 29% of our patients, other chromosomal anomalies in 17%, or associated with other anomalies (not related to VACTERL) in 34% of the patients. The majority of the patients (94%) were of type C-TEF (TEF with esophageal atresia-EA/TEF). All patients were operated except for one patient who died at 2 days of life due to cardiac complications. Median age at which surgery was performed was 2 days (range 1-270 days). Median follow-up was 32 months (range 7-115 months). Immediate postoperative complications were encountered in eleven patients (33%) and included anastomosis leak in 12%, air leak in 6%, sepsis in 6%, chylothorax in 3%, vocal cord palsy and fistula recurrence (combined) in 3%, and failure of TEF closure in 3% of the patients. Long-term respiratory complications were encountered in 43% of our patients. Long-term gastrointestinal complications included gastroesophageal reflux (GERD) in 63%, dysphagia in 31%, and anastomotic stricture in 34% of the patients. Growth was affected in around a quarter of the patients at 6 months after surgery and 22% at 12-month assessment postoperatively. While only five patients died at our institution, only one was directly related to failure of TEF closure and postoperative complications.

Conclusion

This descriptive study reports the clinical outcome of TEF from a rapidly developing country. The distribution of the patients' characteristics and postoperative complications was almost comparable to those from developed countries. This study would aid in addressing the prognostic factors and establishment of evidence-based management pathways of newborns with TEF to improve the clinical outcome in our center and other pediatric tertiary centers in developing countries.

Postoperative Complications of Esophageal Atresia and Role of Endoscopic Balloon Dilatation in Anastomotic Strictures

PURPOSE

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a congenital anomaly that can cause frequent digestive and nutritional problems, even after repair. The most common complication is anastomotic stricture, for which reoperation or balloon dilatation is performed. This study aimed to evaluate the postoperative complications of EA and the role of endoscopic balloon dilatation (EBD) in cases of anastomotic stricture.

METHODS

We retrospectively analyzed patients diagnosed with EA with or without TEF between January 2000 and February 2021. Patients' baseline characteristics, associated anomalies, and postoperative complications were reviewed.

RESULTS

Among 26 patients, 14 (53.8%) were male, 12 (46.2%) had coexisting anomalies, and the median follow-up was 6.1 years (range, 1.2-15.7 years). In univariate analysis, prematurity, low birth weight, and long-gap EA were associated with postoperative complications in 12 (46.2%) patients. Among the 10 (38.5%) patients with anastomotic stricture, nine (90.0%) required EBD. Regarding the first EBD, it was performed at a median of 3.3 months (range, 1.2-7.6 months) post-repair, while the average patient weight was 4.6 kg. The mean diameter ranged from 3.3 to 9.1 mm without major complications. In univariate analysis, long-gap EA alone was significantly associated with EBD.

CONCLUSION

Approximately half of the patients experienced complications after EA repair. In particular, patients with a long-gap EA had a significantly increased risk of complications, such as anastomotic strictures. EBD can be safely used, even in infants.

Clinical variables as indicative factors for endoscopy in adolescents with esophageal atresia

INTRODUCTION

Gastro-esophageal reflux disease (GERD) occurs frequently in patients operated for esophageal atresia (EA). Longstanding esophagitis may lead to dysphagia, strictures, columnar metaplasia, and dysplasia with an increased risk of adenocarcinoma. Are clinical factors and non-invasive assessments reliable indicators for follow-up with endoscopy?

MATERIAL AND METHOD

A follow-up study with inclusion of EA adolescents in Norway born between 1996 and 2002 was conducted. Clinical assessment with pH monitoring, endoscopy with biopsies, along with interviews and questionnaires regarding gastroesophageal reflux disease (GERD) and dysphagia were performed.

RESULTS

We examined 68 EA adolescents. 62% reported GERD by interview, 22% by questionnaire. 85% reported dysphagia by interview, 71% by questionnaire. 24-hour pH monitoring detected pathological reflux index (RI) (>7%) in 7/59 (12%). By endoscopy with biopsy 62 (92%) had histologic esophagitis, of whom 3 (4%) had severe esophagitis. Gastric metaplasia was diagnosed in twelve (18%) adolescents, intestinal metaplasia in only one (1.5%). None had dysplasia or carcinoma. Dysphagia and GERD were statistically correlated to esophagitis and metaplasia, but none of the questionnaires or interviews alone were good screening instruments with high combined sensitivity and specificity. A compound variable made by simply taking the mean of rescaled RI and dysphagia by interview showed to be the best predictor of metaplasia (85% sensitivity, 67% specificity).

CONCLUSION

The questionnaires and interviews used in the present study were not good screening instruments alone. However, combining dysphagia score by interview and RI may be helpful in assessing which patients need endoscopy with biopsy at each individual follow-up examination.

LEVEL OF EVIDENCE

Level II prognostic study.

Endoscopic Injections of Botulinum Toxin Type A in the Piglet Esophagus Is Safe and Feasible but Did Not Result in any Significant Structural Changes 3 Days after Injection

INTRODUCTION

 Treatment for long-gap esophageal atresia (LGEA) aims at achieving primary anastomosis with minimal tension. Previous studies have shown that intramural injections with botulinum toxin type-A (BTX-A) from the adventitial side can increase the elongation of the piglet and rat esophagus before bursting, and that this effect is dose and time dependent. Our aim was to determine if endoscopic injections would be feasible, safe, and with an effect on the mechanical properties of the esophagus.

METHODS

 Twenty-two male piglets (5.15 kg) were randomized into two groups, one receiving 2 units/kg BTX-A, the other equal volume 0.9% NaCl. On day 3, the esophagus was harvested and tested in a stretch-tension machine to evaluate elongation and maximum load, followed by histological examination.

RESULTS

 No adverse effects to the procedure were observed. No statistically significant difference in elongation or maximum load before bursting between the treatment and placebo group was found. In histopathological analysis, inflammation and abscess formation were observed with no statistically significant difference between the two groups.

CONCLUSION

 Endoscopic placement of BTX-A injections in the piglet esophagus was safe and feasible but did not result in any difference in the mechanical properties or histology of the esophagus.

Esophageal Magnetic Anastomosis Device (EMAD) to simplify and improve outcome of thoracoscopic repair for esophageal atresia with tracheoesophageal fistula: A proof of concept study

BACKGROUND

We designed a new Esophageal Magnetic Anastomosis Device (EMAD) for thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) without the need of handheld suturing or additional gastrostomy.

METHODS

Synthetic EA-TEF model: Spherical and tubular shaped rubber balloons and a term infant sized plastic doll were used. Medical students (n = 10) and surgical trainees (n = 10) were asked to perform thoracoscopic repair of an "EA" with a hand sutured anastomosis (HA) and with the EMAD. Euthanized animal model: The esophagus in 5 piglets (3-4 kg) was dissected and a thoracoscopic esophageal magnetic anastomosis (EMA) was performed. Bursting pressure (BP) and pulling force (PF): HA and EMA were created on ex vivo New Zealand white rabbit (2.5-3 kg) esophagi (n = 25 in each test series). BP and PF were measured and compared against each other.

RESULTS

Medical students were unable to complete HA, but were successful with the EMAD in 11.1 ± 2.78 min. Surgical trainees completed EMA in 4.6 ± 2.06 min vs. HA 30.8 ± 4.29 min (p<0.001). The BP following a HA (14.1 ± 3.32 cmH₂O) was close to the physiological intraluminal pressure reported in a neonatal esophagus (around 20 cmH₂O), whereas the BP with the EMAD was extremely high (>90 cmH₂O) (p<0.001). The PF of an EMA (1.8 ± 0.30 N) was closer to the safety limits of anastomotic tension reported in the literature (i.e. 0.75 N) compared with the HA (3.6 ± 0.43 N) (p<0.0001).

CONCLUSION

The EMAD could simplify, shorten, and potentially improve the outcome of thoracoscopic repair for EA with TEF in the future. A high BS and a relative low PF following EMAD application may lower the risk of postoperative complications such as esophageal leakage and stricture formation.

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.

Esophageal magnetic compression anastomosis in dogs

BACKGROUND

Magnetic compression anastomosis (MCA) is a novel suture-free reconstruction of the digestive tract. It has been used in gastrointestinal anastomosis, jejunal anastomosis, cholangioenteric anastomosis and so on. The traditional operative outcomes of congenital esophageal atresia and benign esophageal stricture are poor, and there are too many complications postoperatively.

AIM

To test MCA technology to reconstruct the esophagus in dogs, prior to studying the feasibility and safety of MCA in humans.

METHODS

Thirty-six dogs were randomized into either the study or control group (n = 18 per group). The dogs in the study group were subjected to end-to-end esophageal anastomosis with the magnetic compression device, while those in the control group underwent hand-sewn anastomosis with 4-0 absorbable multifilament Vicryl. We used interrupted single-layer inverting sutures. The anastomosis time, gross appearance, weight and pathology of the anastomosis were evaluated at one month, three months and six months postoperatively.

RESULTS

The anastomosis time of the MCA group was shorter than that of the hand-sewn group (7.5 ± 1.0 min vs 12.5 ± 1.8 min, P < 0.01). In the MCA group, X-ray examination was performed every day to locate the magnetic device in the esophagus before the magnetic device fell off from the esophagus. In the hand-sewn group, dogs did not undergo X-ray examination. One month after the surgeries, the mean weight of the dogs in the hand-sewn group had decreased more than that of the dogs in the MCA group (11.63 ± 0.71 kg vs 12.73 ± 0.80 kg, P < 0.05). At 3 mo and 6 mo after the operation, the dogs' weights were similar between the two groups (13.75 ± 0.84 kg vs 14.03 ± 0.82 kg, 14.93 ± 0.80 kg vs 15.44 ± 0.47 kg). The number of inflammatory cells in MCA group was lower than that in hand-sewn group on 1 mo after operation.

CONCLUSION

MCA is an effective and safe method for esophageal reconstruction. The anastomosis time of the MCA group was less than that of the hand-sewn group. This study shows that MCA technology may be applied to human esophageal reconstruction, provided these favorable results are confirmed by more publications.

Outcome of esophageal atresia: inborn versus outborn patients

Esophageal atresia (EA) is a rare congenital disease which is usually not of the detected prenatally. Due to the lack of prenatal diagnosis, some newborns with EA are born outside of specialized centers. Nevertheless, centralized care of EA has been proposed, even if a clear volume-outcome association in EA management remains unconfirmed. Furthermore, whether outcomes differ between outborn and inborn patients with EA has not been systematically investigated. Therefore, this single-center, retrospective study aimed to investigate EA management and outcomes with a special focus on inborn versus outborn patients. The following data were extracted from the medical records of infants with EA from 2009 to 2019: EA type, associated anomalies, complications, and long-term outcome. Patients were allocated into inborn and outborn groups. Altogether, 57 patients were included. Five patients were excluded (referral before surgery, loss of data, death before surgery [n = 1], and incorrect diagnosis [diverticulum, n = 1]). Among all patients, the overall survival rate was 96%, with no mortalities among outborn patients. The overall hospitalization period was shorter for outborn patients. The median follow-up durations were 3.8 years and 3.2 years for inborn and outborn patients, respectively. Overall, 15% of patients underwent delayed primary anastomosis (long-gap atresia [n = 4] and other reasons [n = 4]). Early complications included three anastomotic leakages and one post-operative fistula; 28% of patients developed strictures, which required dilatation, and 38% of patients showed relevant gastroesophageal reflux, which required fundoplication, without any differences between the groups. The two groups had comparable low mortality and expected high morbidity with no significant differences in outcome. The outborn group showed nonsignificant trends toward lower morbidity and shorter hospitalization periods, which might be explained by the overall better clinical status.

Whether prophylactic intraoperative chest drain insertion in esophageal atresia-tracheoesophageal fistula is an evidence-based practice or just a prejudice: A systematic review and meta-analysis

BACKGROUND

Various controversial practices in the management of Esophageal atresia-tracheoesophageal fistula (EA-TEF) can be noticed among pediatric surgeons. Routine intraoperative chest drain (IOCD) insertion is often debated and lacks any concrete evidence. This meta-analysis aims to compare the postoperative outcomes among newborns with and without IOCD insertion.

METHODS

The authors searched EMBASE, PubMed, Scopus, and Web of Science on 30^th April 2021. The requirement for chest drain in the postoperative period (POCD), anastomotic leak (and/or pneumothorax), mortality rate, and revisit(s) to the operation room (RVOR) were compared among two groups of newborns, i.e. groups A and B with and without IOCD insertion respectively. The statistical analysis was performed using a fixed-effects model. The pooled risk ratio (RR) and heterogeneity (I²) were calculated. The methodological quality of the studies was assessed utilizing the Downs and Black scale.

RESULTS

A total of 498 newborns were included in the present analysis. As compared to group B, newborns within group A showed no significant difference in the requirement for POCD (RR 2.47; 95% CI 0.88-6.98, p = 0.09), the occurrence of anastomotic leak and/or pneumothorax (RR 1.35; 95% CI 0.89-2.06, p = 0.16), and mortality rate (RR 2.24; 95% CI 0.81-6.26, p = 0.12). However, RVOR was significantly higher in group A (RR 1.75; 95% CI 1.07-2.87, p = 0.03). All included studies had a moderate risk of bias.

CONCLUSIONS

The present meta-analysis revealed no additional benefit of prophylactic IOCD insertion. However, due to moderate risk of bias, further studies need to be conducted for an optimal comparison between the two groups.

Long-Term Outcomes and Health-Related Quality of Life in a Swiss Patient Group with Esophageal Atresia

INTRODUCTION

 Surgical treatment of esophageal atresia (EA) has markedly improved, allowing the focus to shift from short-term complications and mortality to long-term complications and quality of life. Health-related quality of life (HRQoL) is variable and reported to range from reduced to unimpaired in patients with repaired EA. We assessed the HRQoL, determined the prevalence of long-term complications and their possible impact on the HRQoL in patients who had correction of EA in Switzerland. Further, we also investigated in the general well-being of their parents.

MATERIALS AND METHODS

 Patients with EA repair in Switzerland between 1985 and 2011 were enrolled. Long-term complications were assessed by enquiring disease-related symptoms, standardized clinical examinations, and analysis of radiographs. HRQoL was inquired using different validated questionnaires (KIDSCREEN-27, World Health Organization [WHO]-5, and Gastrointestinal Quality of Life Index [GIQLI]). Patients were grouped according to their age. In underage patients, general well-being of the parents was assessed using the WHO-5 questionnaire.

RESULTS

 Thirty patients were included with a mean age of 11.3 ± 5.7 years. Long-term complications were present in 63% of all patients. HRQoL in underage patients was comparable to the provided reference values and rated as good, while adult patients reported a reduced HRQoL. The presence of gastroesophageal reflux disease symptoms was associated with reduced HRQoL in underage patients. Parents of underage patients stated a good general well-being.

CONCLUSION

 Long-term complications among patients with repair of EA in Switzerland are common. HRQoL in underage patients is good and general well-being of their parents is unimpaired. Adult patients reported a reduced HRQoL, consistent with other reports. As long-term complications may manifest only later in life, a structured follow-up of patients with an EA repair during childhood and adolescence is needed.

Traumatic stress, mental health, and quality of life in adolescents with esophageal atresia

INTRODUCTION

We aimed to investigate QoL in EA patients in relation to comparison groups and to clinical factors including experienced traumatic stress.

MATERIAL AND METHODS

Adolescents with EA in Norway born between 1996 and 2002 were included. Clinical assessment and patient's characteristics were collected. Quality of life (PedsQL), traumatic stress (IES-13) and mental health (SDQ-20) were compared to groups of healthy controls, children with acute lymphoblastic leukemia (ALL) and kidney transplanted children (TX).

RESULTS

68 EA adolescents participated. Total scores for PedsQL were not different from the healthy group and ALL patients, but significantly better than the TX patients. The subscale for physical performance was significantly lower than in healthy adolescents, and nine (17%) patients had scores ≤70 indicating reduced health status. Five EA adolescents (12%) had mental health scores suggesting a psychiatric disorder, and six (9%) reported high traumatic stress scores with a significant correlation to days on ventilator in the neonatal period. The strongest predictors for quality of life among EA adolescents were self-reported mental health, posttraumatic stress and GERD symptoms.

CONCLUSION

Scores for Quality of life in the EA group are good except for subscale for physical performance. Symptoms of posttraumatic stress, mental strain and gastroesophageal reflux are predictors of reduced QoL.

Time to Death and Predictors Among Neonates with Esophageal Atresia in Ethiopia

Background

Esophageal atresia is an upper gastrointestinal tract developmental abnormality in which the upper and lower esophagus do not connect. Esophageal atresia has a higher incidence of death in sub-Saharan Africa, ranging from 30% to 80%. In Ethiopia, infants with esophageal atresia had a higher mortality rate. The assessment of time to death and predictors of esophageal atresia can help to reduce newborn mortality.

Objective

This study was aimed to investigate the time to death and predictors of neonates with esophageal atresia admitted to Tikur Anbessa Specialized Hospital, Ethiopia.

Methods

An institutional-based retrospective follow-up study was conducted among 225 neonates diagnosed with esophageal atresia. The median survival time, Kaplan–Meier failure estimation curve, and Log rank test were computed. Bivariable and multivariable Cox regression hazards models were fitted to identify the predictors of time to death. Hazard ratio with a 95% confidence interval was calculated and p-values <0.05 were considered statistically significant.

Results

In the study, the incidence density rate of neonates diagnosed with esophageal atresia was 5.5 (95% CI, 4.7–6.4) per 100-neonates day. The median time to death was 11 days (95% confidence interval (CI), 8.92–13.08). Birth weight <2500 g (adjusted hazard ratio (AHR)=1.49, 95% CI, 1.02 −2.21), having sepsis (AHR=1.67,95% CI, 1.15–2.44), being malnourished (AHR = 1.61, 95% CI, 1.03 −2.58), esophageal atretic neonates without surgery (AHR = 3.72, 95% CI, 1.34–10.38), diagnosis time at >48 hours of admission (AHR = 1.48, 95% CI, 1.01–2.15) and being dehydrated (AHR = 2.38, 95% CI, 1.63–3.46) were significant predictors of time to death among esophageal atretic neonates.

Conclusion

The findings in this study highlighted the necessity of early diagnosis, proper comorbidity treatment, and timely surgical intervention to reduce infant deaths due to esophageal atresia.

From the Ground Up: Esophageal Atresia Types, Disease Severity Stratification and Survival Rates at a Single Institution

Esophageal atresia (EA), although a rare congenital anomaly, represents one of the most common gastrointestinal birth defects. There is a gap in our knowledge regarding the impact of perioperative critical care in infants born with EA. This study addresses EA types, disease severity stratification, and mortality in a retrospective cohort at a single institution. Institutional Review Board approved our retrospective cross-sectional study of term-born (n = 53) and premature infants (28–37 weeks of gestation; n = 31) that underwent primary surgical repair of EA at a single institution from 2009–2020. Demographic and clinical data were obtained from the electronic medical record, Powerchart (Cerner, London, UK). Patients were categorized by (i) sex, (ii) gestational age at birth, (iii) types of EA (in relation to respiratory tract anomalies), (iv) co-occurring congenital anomalies, (v) severity of disease (viz. American Society of Anesthesiologists (ASA) and Pediatric Risk Assessment (PRAm) scores), (vi) type of surgical repair for EA (primary anastomosis vs. Foker process), and (vii) survival rate classification using Spitz and Waterston scores. Data were presented as numerical sums and percentages. The frequency of anatomical types of EA in our cohort parallels that of the literature: 9.5% (8/84) type A, 9.5% (8/84) type B, 80% (67/84) type C, and 1% (1/84) type D. Long-gap EA accounts for 88% (7/8) type A, 75% (6/8) type B, and 13% (9/67) type C in the cohort studied. Our novel results show a nearly equal distribution of sex per each EA type, and gestational age (term-born vs. premature) by anatomical EA type. PRAm scoring showed a wider range of disease severity (3–9) than ASA scores (III and IV). The survival rate in our EA cohort dramatically increased in comparison to the literature in previous decades. This retrospective analysis at a single institution shows incidence of EA per sex and gestational status for anatomical types (EA type A-D) and by surgical approach (primary anastomosis vs. Foker process for short-gap vs. long-gap EA, respectively). Despite its wider range, PRAm score was not more useful in predicting disease severity in comparison to ASA score. Increased survival rates over the last decade suggest a potential need to assess unique operative and perioperative risks in this unique population of patients. Presented findings also represent a foundation for future clinical studies of outcomes in infants born with EA.

Long proximal pouch oesophageal atresia with tracheo-oesophageal fistula, a diagnostic dilemma: case report

Background

Oesophageal atresia is a congenital abnormality commonly encountered in neonates. Classification proposed by Gross is the most frequently used. It divides the oesophageal anomalies into five types. Type C—proximal oesophageal atresia and distal tracheo-oesophageal fistula—is the most common. Dafoe and Ross described a rare subtype with a long proximal pouch. Only 11 cases of a long proximal pouch have been reported in the English literature so far. We describe a neonate with long proximal pouch oesophageal atresia with distal tracheo-oesophageal fistula emphasizing the difficulty in arriving at the diagnosis.

Case presentation

A 1-week-old neonate presented with feed intolerance and failure to advance orogastric tube into the stomach. Water soluble upper gastrointestinal tract contrast revealed a blind ending proximal oesophagus at the level of the diaphragm. Gastric volvulus was considered as a diagnosis. Patient underwent a laparotomy where a normal stomach was found. Bubbles were seen coming from the fashioned gastrostomy with each inspiration. This prompted us to consider the possibility of a missed oesophageal atresia with distal tracheo-oesophageal fistula. Diagnosis was confirmed on bronchoscopy and right thoracotomy. The tracheo-oesophageal fistula was ligated and a cervical oesophagostomy and Stamm gastrostomy were performed due to irreparable tear in the long upper pouch.

Conclusion

This rare subtype of long upper pouch oesophageal atresia poses a diagnostic dilemma that can result in delay in the diagnosis and management. This diagnosis should be suspected if the tip of the orogastric/feeding tube is seen to be far below the level of the carina.

Pediatric esophageal stenoses: Challenges and new surgical device promoting tension-free esophageal anastomosis

Esophageal stenoses of childhood have a broad spectrum of underlying causes. Their treatment is usually minimally invasive by endoscopic means, but sometimes surgery is necessary in refractory cases. Techniques employed in the surgical treatment of esophageal strictures include resection of the stenotic esophageal segment or esophageal substitution procedures. Esophageal anastomosis has always been a challenge in pediatric surgery. Anastomosis complications are linked to anatomical, biological and technical aspects. Mechanical tension between esophageal ends is an important cause of complications including anastomotic leaks or dehiscence. Eleven cases of esophageal stenoses, surgically treated in the Pediatric Surgery Department of Emergency Clinical Hospital for Children 'Marie S. Curie' by a single team in 5 years, were included in the present study. The results showed that, the main causes of esophageal stenosis were represented by corrosive esophageal injury in five cases, complications of esophageal atresia repair in three cases, congenital esophageal stenosis in two cases and chemotherapy-induced esophageal necrosis in acute lymphoblastic leukemia treatment in one case. The authors also designed and presented a device facilitating esophageal anastomosis under tension. Its principle involved temporary absorption of tension at secure points of the two esophageal pouches and reallocating it in equal amounts following anastomosis while decreasing any stretch-related tissue trauma. In conclusion, this auxiliary tool is beneficial for esophageal anastomosis; however, the standard steps of the esophageal anastomosis procedure should still be considered when necessary.

Congenital Esophageal Atresia Long-Term Follow-Up-The Pediatric Surgeon's Duty to Focus on Quality of Life

Esophageal atresia (EA) is the most common congenital esophageal malformation. An improvement in survival led to a focus on functional outcomes and quality of life (QoL). We analyzed the long-term outcomes and QoL of patients submitted to surgery for EA. Perinatal characteristics, surgical procedures, gastrointestinal and respiratory current symptoms and QoL were investigated. Thirty-nine patients were included. Long Gap patients had a higher rate of prematurity and low birth weight. The prevalent surgical procedure was primary esophageal anastomosis, followed by gastric pull-up. Twenty-four patients had post-operative stenosis, while gastroesophageal reflux (GER) required fundoplication in eleven cases. Auxological parameters were lower in Long Gap patients. The lowest scores of QoL were in the Long Gap group, especially in younger patients, which was the group with the highest number of symptoms. In the long term, the QoL appeared to be more dependent on the type of esophageal atresia rather than on associated malformations. Surgical management of GER was indicated in all patients with Long Gap EA, supposedly due to the prevalence of gastric pull-up for this type of EA. The assessment of QoL is part of surgeon’s management and needs to be performed in each phase of a child’s development.

Review of Complications of Operated Esophageal Atresia and Tracheoesophageal Fistula Patients

Objective

This study was aimed to investigate the complications arising during follow-up and the reasons for hospitalization in pediatric patients who were operated on for esophageal atresia (EA) and tracheoesophageal fistula (TEF).

Materials and Methods

Between 2007 and 2019, all patients operated for EA and TEF were evaluated in terms of age, gender, age at diagnosis, post-op, and complications in follow-up.

Results

In the study, 28 of 50 patients were operated on for EA and TEF, 14 for isolated EA, and 8 for isolated TEF. The mean age of the patients was 4.9 ± 4.4 years, and 18 (36%) of them were female. The median age of diagnosis was 1 (IQR: 1-3) day and the mean follow-up duration was 4.6 ± 4.1 years. During follow-up, 84% of patients had recurrent pneumonia, 60% gastroesophageal reflux (GER), 34% growth retardation, 30% restrictive lung disease, and 18% scoliosis. Postoperative pneumonia, hospitalization, development of stricture and growth retardation were more frequent in patients with GER (P < .05). Patients with scoliosis had more frequent pneumonia and hospitalization rates (P < .05).

Conclusion

Hospital admissions of the patients with EA and TEF were higher due to GER, recurrent pneumonia, restrictive lung disease, and scoliosis in the follow-up. Pneumonia, hospitalization, stricture in the esophagus, and growth retardation were observed more frequently in patients with GER. Patients should be followed up by the pediatric pulmonology, gastroenterology, and orthopedic departments.

Esophageal regeneration following surgical implantation of a tissue engineered esophageal implant in a pediatric model

Diseases of the esophagus, damage of the esophagus due to injury or congenital defects during fetal esophageal development, i.e., esophageal atresia (EA), typically require surgical intervention to restore esophageal continuity. The development of tissue engineered tubular structures would improve the treatment options for these conditions by providing an alternative that is organ sparing and can be manufactured to fit the exact dimensions of the defect. An autologous tissue engineered Cellspan Esophageal Implant^TM (CEI) was surgically implanted into piglets that underwent surgical resection of the esophagus. Multiple survival time points, post-implantation, were analyzed histologically to understand the tissue architecture and time course of the regeneration process. In addition, we investigated CT imaging as an “in-life” monitoring protocol to assess tissue regeneration. We also utilized a clinically relevant animal management paradigm that was essential for long term survival. Following implantation, CT imaging revealed early tissue deposition and the formation of a contiguous tissue conduit. Endoscopic evaluation at multiple time points revealed complete epithelialization of the lumenal surface by day 90. Histologic evaluation at several necropsy time points, post-implantation, determined the time course of tissue regeneration and demonstrated that the tissue continues to remodel over the course of a 1-year survival time period, resulting in the development of esophageal structural features, including the mucosal epithelium, muscularis mucosae, lamina propria, as well as smooth muscle proliferation/migration initiating the formation of a laminated adventitia. Long term survival (1 year) demonstrated restoration of oral nutrition, normal animal growth and the overall safety of this treatment regimen.

Gastric Transposition for Repair of Long-Gap Esophageal Atresia: Indications, Complications, and Outcome of Minimally Invasive and Open Surgery

BACKGROUND

Gastric transposition (GT) is a possible option for esophageal replacement in long-gap esophageal atresia (LGEA). The present study aims to report and compare indications and outcome of laparoscopic-assisted GT (LAGT) versus open (OGT) GT for LGEA repair.

METHODS

Retrospective single-center analysis of all LGEA patients undergoing GT between 2002 and 2021.

RESULTS

Thirty-one children with LGEA underwent GT. Of these, 19 underwent LAGT (mean weight at surgery 5.6 kg; mean age 167 days) and 12 underwent OGT (6.1 kg; 233 days). Indications for OGT were previous surgery (n = 7), associated severe cardiac malformations (n = 4), and a simultaneous resection of a choledochal cyst (n = 1). The conversion rate was 1. The two procedures (LAGT/OGT) differed in anesthetic time (308/350 min), duration of ventilation (5.1/5.3 days), hospital stay (34/32 days), and complications (22/15). None of the differences reached statistical significance. Outcome was also comparable: completely oral nutrition uptake in 66%/73%, slow weight gain in the low centiles in both groups, no patient developed dumping syndrome, symptomatic reflux was seen in 1 patient after OGT.

CONCLUSION

In our cohort, LAGT for repair of LGEA provided similar outcomes as open surgery. The minimally invasive approach preserves thoracal structures, prevents additional thoracotomy or laparotomy, and is faster. To realize LAGT, a postpartal treatment concept including gastrostomy placement via a microincision to minimize adhesions is essential. The open surgical approach should be considered in cases of previous extensive surgical attempts of EA correction causing severe adhesions as well as associated anomalies or genetic syndromes causing hemodynamic instability.

Esophageal Dysphagia in Children: State of the Art and Proposal for a Symptom-Based Diagnostic Approach

Pediatric esophageal dysphagia (PED) is an infrequent condition that can be determined by a large number of disorders. The etiologic diagnosis is challenging due to overlapping clinical phenotypes and to the absence of pediatric diagnostic guidelines. This review aims to summarize the most relevant causes of ED during childhood, highlight the clinical scenarios of PED presentation and discuss the indications of available diagnostic tools. Available information supports that PED should always be investigated as it can underlie life-threatening conditions (e.g., foreign body ingestion, mediastinal tumors), represent the complication of benign disorders (e.g., peptic stenosis) or constitute the manifestation of organic diseases (e.g., eosinophilic esophagitis, achalasia). Therefore, the diagnosis of functional PED should be made only after excluding mucosal, structural, or motility esophageal abnormalities. Several clinical features may contribute to the diagnosis of PED. Among the latter, we identified several clinical key elements, relevant complementary-symptoms and predisposing factors, and organized them in a multi-level, hierarchical, circle diagram able to guide the clinician through the diagnostic work-up of PED. The most appropriate investigational method(s) should be chosen based on the diagnostic hypothesis: esophagogastroduodenoscopy has highest diagnostic yield for mucosal disorders, barium swallow has greater sensitivity in detecting achalasia and structural abnormalities, chest CT/MR inform on the mediastinum, manometry is most sensitive in detecting motility disorders, while pH-MII measures gastroesophageal reflux. Further studies are needed to define the epidemiology of PED, determine the prevalence of individual underlying etiologies, and assess the diagnostic value of investigational methods as to develop a reliable diagnostic algorithm.

Musculoskeletal and Esthetic Complications after Neonatal Thoracotomy: Revisited

AIM

The aim is to study the complications of neonatal thoracotomy and its preventive measures.

METHODS

We retrospectively reviewed 53 neonates who underwent thoracotomy from January 2017 to December 2019 for a period of 3 years. Patient demographic data, primary disease for which they underwent thoracotomy, postoperative complications (immediate and delayed) during follow-up were documented.

RESULTS

During 3-year period, 53 neonates underwent thoracotomy for various surgical pathologies. The indications were esophageal atresia with tracheoesophageal fistula (n = 49), eventration of diaphragm (n = 3), congenital lobar emphysema of left upper lobe of lung (n = 1). Most of them were right posterolateral thoracotomies (n = 48, 90.56%) and left posterolateral thoracotomy was done in only 5 cases (9.43%). Associated anomalies were seen in 22 cases, such as cardiac (n = 19), renal (n = 4) and gastrointestinal (n = 5). Associated comorbidities seen in 14 cases; preterm (n = 4), low birth weight (n = 13), delayed presentation (n = 6). Early postoperative complications such as pneumonia (34%, n = 18) and wound infection (11.3%, n = 6) were noted. Delayed complications include musculoskeletal abnormalities (n = 19, 35.8%) and esthetic complications such as asymmetry of chest (5.6%).

CONCLUSION

Neonatal thoracotomy is associated with complications such as pneumonia, wound infections, and musculoskeletal abnormalities such as asymmetry of chest and scoliosis. These can be prevented by adequate postoperative pain relief, muscle-sparing thoracotomies, avoiding tight closures, and nerve injuries. Long-term follow-up is required because these complications may manifest later on also. Early detection and institution of physiotherapy may help.

Retrospective analysis of pneumothorax after repair of esophageal atresia/tracheoesophageal fistula

Background

To analyze the possible causes, treatment and outcomes of postoperative pneumothorax in patients with Gross type C esophageal atresia/tracheoesophageal fistula (EA/TEF).

Methods

Medical records of patients with Gross type C EA/TEF who were diagnosed and treated in Beijing Children’s Hospital from January 2007 to January 2020 were retrospectively collected. They were divided into 2 groups according to whether postoperative pneumothorax occurred. Univariate and multivariate logistic regression analysis were performed to identify risk factors for pneumothorax.

Results

A total of 188 patients were included, including 85 (45 %) in the pneumothorax group and 103 (55 %) in the non-pneumothorax group. Multivariate logistic regression analysis showed that postoperative anastomotic leakage [P < 0.001, OR 3.516 (1.859, 6.648)] and mechanical ventilation [P = 0.012, OR 2.399 (1.210, 4.758)] were independent risk factors for pneumothorax after EA/TEF repair. Further analysis of main parameters of mechanical ventilation after surgery showed that none of them were clearly related to the occurrence of pneumothorax. Among the 85 patients with pneumothorax, 33 gave up after surgery and 52 received further treatment [conservative observation (n = 20), pleural puncture (n = 11), pleural closed drainage (n = 9), both pleural puncture and closed drainage (n = 12)]. All of the 52 patients were cured of pneumothorax at discharge.

Conclusions

Anastomotic leakage and postoperative mechanical ventilation were risk factors for pneumothorax after repair of Gross type C EA/TEF, but the main parameters of mechanical ventilation had no clear correlation with pneumothorax. After symptomatic treatment, the prognosis of pneumothorax was good.

Impaired motor performance in adolescents with esophageal atresia

AIMS

The study prospectively assessed motor development from infancy to adolescence in patients with esophageal atresia (EA).

METHODS

At one year of age motor performance was evaluated with the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development, Second Edition (BSID-II), and as adolescents reevaluated with Motor Assessment Battery for Children, Second Edition (MABC-2). Associations to clinical factors were assessed.

RESULTS

23 EA patients were followed from infancy to adolescence. The median total PDI score in infancy was 102 (56-118) and the corresponding mean z-score was -0.006 (SD 0.995) and not significantly different from the reference values (p = 0.48). The median total MABC-2 score in adolescence was 75 (32-93) and the corresponding mean z-score -0.43 (SD 0.998) which is significantly below normal (p = 0.03). Children with impaired motor function in adolescence underwent significantly more rethoracotomies than those with normal motor performance (p = 0.037); whereas the two groups did not differ with respect to other clinical characteristics.

CONCLUSION

From infancy to adolescence the motor performance in the group of EA patients deteriorated from within normal range to significantly impaired compared to reference values. Interdisciplinary follow-up programs from infancy to adolescence with close monitoring for motor function is necessary to detect motor impairments.

A rare congenital esophageal anomaly mimicking an isolated esophageal atresia: Kluth Type IV1a membranous esophageal atresia

Congenital esophageal web is a very rare type of esophageal atresia (EA) and is considered as Type IV atresia in Kluth's classification. Type IV EA is further classified into subgroups according to the location of web and the presence of tracheoesophageal fistula (TEF). Herein, we present a newborn having Type IV_1a EA who was initially suspected as isolated EA and has co-existing malrotation together with the review of the literature. A newborn having congenital esophageal web was admitted with antenatal ultrasonography revealing polyhydramnios, dilated stomach, and duodenum. Abdominal X-ray revealed a gasless abdomen suggesting isolated EA. The upper gastrointestinal series confirmed complete obstruction at the lower esophagus. Bronchoscopy performed excluding TEF. Laparotomy revealed intestinal malrotation and the absence of another GI webs. Gastrotomy was performed and mucosal web at GEJ was seen by pushing nasogastric catheter. Web excision and Ladd procedure were performed. Congenital esophageal web is an extremely rare type of esophageal anomaly that can be only classified in Kluth classification. A high index of suspicion is required for diagnosis especially in newborns with the gasless abdomen and esophageal obstruction at the level of GEJ. Preoperative bronchoscopy is mandatory to exclude an associating TEF. Surgical exploration via laparotomy is beneficial for exploring additional GIS anomalies.

Oral Health Status among Children with Repaired Esophageal Atresia

INTRODUCTION

 Esophageal atresia (EA) is a congenital anomaly, presenting multifactorial etiology. Swallowing problems and gastroesophageal reflux disease may accompany EA, which have adverse effects on oral health.

MATERIALS AND METHODS

 In this descriptive study, intraoral examination of the children with repaired EA and of the dental patients without systemic/chronic disease was performed. Dental caries, dental erosion, and halitosis status were evaluated using the International Caries Detection and Evaluation System II, and the Basic Erosive Wear Examination indices as well as the Halimeter, respectively.

RESULTS

 There were 19 (n = 12 male; n = 7 female) case subjects and 16 (n = 10 male; n = 6 female) control subjects whose age ranged between 14 and 72 months. Among cases, 15 children had dental caries (78.9%; initial caries n = 4, moderate caries n = 4, and extensive caries n = 7). Of the controls, 13 had dental caries (81.2%; initial caries n = 5, moderate caries n = 5, and extensive caries n = 3). Although the median scores of decayed, missing, filled teeth (dmft) and decayed, missing, filled surfaces (dmfs)-for primary dentition-were not statistically significantly different between two groups, both dmft and dmfs were found to be higher among the case subjects (p = 0.172 for dmft; p = 0.230 for dmfs). Furthermore, six children with repaired EA had dental abnormalities (in shape, number, or calcification) and six children with repaired EA had dental erosion. The Halimeter measurement was performed for five case children of whom three had oral malodor, and for seven control children of whom two had oral malodor.

CONCLUSION

 Regular dental counseling adopting the multidisciplinary team approach for patients with EA is necessary to ensure better general and oral health.

Anastomotic stricture indexes for endoscopic balloon dilation after esophageal atresia repair: a single-center study

We investigated changes in anastomotic stricture indexes (SIs) and stricture diameter (SD) between before and 6 months after the first dilatation in children with anastomotic stricture after esophageal atresia (EA) repair and identified predictors of medium-term dilatation success (success for at least 3 months). We retrospectively reviewed the records and measurement indexes of patients who underwent post-EA repair endoscopic balloon dilatation between November 2017 and August 2019 in our hospital. We identified diagnostic and performance indicators that predicted medium-term dilatation success by univariate and multivariate analyses and receiver operator characteristic (ROC) curve analysis. Sixty patients (34 boys and 26 girls) showed post-EA repair anastomotic stricture. Paired sample t-tests showed that SD (P < 0.001), upper pouch SI (U-SI, P < 0.001), lower pouch SI (L-SI, P < 0.001), upper pouch esophageal anastomotic SI (U-EASI, P < 0.001) and lower pouch EASI (L-EASI, P < 0.001) were significantly better at 6 months after than before the first dilatation. Logistic regression analysis showed that dilatation number (P = 0.002) and U-SI at 6 months after the first dilatation (P = 0.019) significantly predicted medium-term dilatation success. ROC curve analysis revealed that combining U-SI (cut-off value = 55.6%) and dilatation number (cut-off value = 10) had good accuracy in predicting medium-term dilatation success 6 months after the first dilatation (area under the curve-ROC: 0.95). In conclusion, endoscopic balloon dilatation significantly improved SD and SIs in children with post-EA repair anastomotic stricture. Dilatation number and U-SI at 6 months after the first dilatation were useful in predicting medium-term dilatation success and could represent a supplementary method to improve judgment regarding whether further dilatation is needed 6 months after the first dilatation.
