Comparison of clinical outcomes between open and thoracoscopic repair for esophageal atresia with tracheoesophageal fistula: a systematic review and meta-analysis

Are Low Weight or Cardiopathy Contraindications for Thoracoscopic Repair of Esophageal Atresia with Tracheoesophageal Fistula?

BACKGROUND

 Thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) is becoming an increasingly widespread technique; there is still controversy about its indication in certain patients. Our objective is to analyze if potential risk factors such as major congenital heart disease (CHD) or low birth weight (LBW) are a limitation to this approach.

METHODS

 Retrospective study (2017-2021) of patients with EA and distal TEF who underwent thoracoscopic repair were included. Patients with LBW less than 2,000 g or major CHD were compared with the rest.

RESULTS

 Twenty-five patients underwent thoracoscopic surgery. Nine patients (36%) had major CHD. Five of them (20%) were LBW less than 2,000 g, and only 8% (2/25) presented both risk factors. There were no differences in terms of operative time, conversion rate, tolerance evaluated with gasometric parameters (pO2, pCO2, pH) or complications (anastomotic leak and stricture, both early or during follow-up) in patients with major CHD and LBW (1,473 ± 319 vs. 2,664 ± 402 g). One conversion to thoracotomy was performed in a neonate weighing 1,050 g due to anesthetic intolerance. There was no recurrence of TEF. One patient died at the age of 9 months, due to major uncorrectable heart disease.

CONCLUSION

 Thoracoscopic repair of EA/TEF is feasible technique in patients with CHD or LBW, with similar results to other patients. The complexity of this technique warrants individualizing the indication in each case.

Musculoskeletal deformities after thoracoscopic versus conventional open repair for esophageal atresia

BACKGROUND

The superiority of thoracoscopic repair (TR) over conventional open repair (COR) for esophageal atresia, especially in terms of long-term outcomes, remains to be investigated. The aim of this study was to compare short- and long-term results between TR and COR group.

METHODS

Patients who underwent TR or COR for esophageal atresia without other predispositions to musculoskeletal deformities (2003-2016) and had been followed up for a minimum of 5 years were retrospectively reviewed. Musculoskeletal deformities (e.g., scoliosis, chest wall asymmetry, and rib deformities) were mainly evaluated based on the most recent chest radiographs.

RESULTS

Nine and eight patients were included in the TR and COR groups, respectively; the mean follow-up period was 8.7 and 11.5 years, respectively (p = 0.14). These groups had similar epidemiological characteristics and rates of postoperative complications. Musculoskeletal deformities developed significantly less frequently in the TR group versus the COR group (11 % vs. 88 %, p < 0.05; scoliosis: 0 % vs. 38 %, p = 0.08; chest wall asymmetry: 11 % vs. 50 %, p = 0.14; and rib deformities: 11 % vs. 88 %, p < 0.05, respectively).

CONCLUSION

TR was associated with a decreased incidence of musculoskeletal deformities and comparable complication rates versus COR for esophageal atresia repair. TR may achieve better long-term outcomes in this setting.

Risk factors for postoperative anastomotic leakage after repair of esophageal atresia: a retrospective nationwide database study

PURPOSE

Postoperative anastomotic leakage is the most frequent short-term complication of esophageal atresia repair in neonates. We conducted this study using a nationwide surgical database in Japan to identify the risk factors for anastomotic leakage in neonates undergoing esophageal atresia repair.

METHODS

Neonates diagnosed with esophageal atresia between 2015 and 2019 were identified in the National Clinical Database. Postoperative anastomotic leakage was compared among patients to identify the potential risk factors, using univariate analysis. Multivariable logistic regression analysis included sex, gestational age, thoracoscopic repair, staged repair, and procedure time as independent variables.

RESULTS

We identified 667 patients, with an overall leakage incidence of 7.8% (n = 52). Anastomotic leakage was more likely in patients who underwent staged repairs than in those who did not (21.2% vs. 5.2%, respectively) and in patients with a procedure time > 3.5 h than in those with a procedure time < 3.5 h (12.6% vs. 3.0%, respectively; p < 0.001). Multivariable logistic regression analysis identified staged repair (odds ratio [OR] 4.89, 95% confidence interval [CI] 2.22-10.16, p < 0.001) and a longer procedure time (OR 4.65, 95% CI 2.38-9.95, p < 0.001) as risk factors associated with postoperative leakage.

CONCLUSION

Staged procedures and long operative times are associated with postoperative anastomotic leakage, suggesting that leakage is more likely after complex esophageal atresia repair and that such patients require refined treatment strategies.

Morbidity and mortality among neonates with esophageal atresia and/or tracheoesophageal fistula in the United States

BACKGROUND

Although rare, esophageal atresia (EA) and/or tracheoesophageal fistula (TEF) can lead to severe morbidity and mortality. A known complication of EA and/or TEF repair is vocal fold motion impairment (VFMI).

OBJECTIVE

To characterize the prevalence of VFMI among repaired EA and/or TEF at a national level and to identify factors associated with in-patient mortality and common clinical endpoints in this population (tracheostomy and gastrostomy tube dependence).

METHODS

This is a retrospective cohort study of inpatient neonate admissions with EA and/or TEF in the 2016 Kids' Inpatient Database (KID). Patients with a history of EA and/or TEF were identified with ICD-10 codes. VFMI prevalence was assessed by observed frequencies and percentages. Clinical endpoints included gastrostomy (G-)tube placement, tracheostomy status, and inpatient mortality. Potential predictors of these three primary outcomes included cardiac anomalies, airway disorders, chromosomal anomalies, surgery within 24 h of admission, prematurity, and low birthweight (LBW). Chi-squared analysis was performed between each parameter and the primary outcomes. Significant associations (p-value<0.05) were further assessed with multivariate logistic regression.

RESULTS

Of 1062 neonates with history of EA and/or TEF, 24 (2.3%) had VFMI. Among this population, 27 patients underwent tracheostomies and 63 required G-tubes. There was a significantly higher likelihood of tracheostomy in patients with VFMI compared to patients without (16.7% versus 2.2%; p < 0.01). After multivariate analysis, birthweight less than 1.5 kg (BW < 1.5 kg; OR = 2.5, 95% CI: 1.03-6.10), extreme prematurity (OR = 7.5, 95% CI: 2.00-28.07), cardiac anomalies (OR = 1.8, 95% CI: 1.01-3.04) and chromosomal anomalies (OR = 4.2, 95% CI: 2.39-7.44) were significantly associated with in-hospital mortality. Bronchopulmonary dysplasia (BPD; OR = 4.7, 95% CI: 1.73-12.78) and BW < 1.5 kg (OR = 2.4, 95% CI: 1.05-5.49) were significant predictors for G-tube status. For tracheostomy, BPD (OR = 15.8, 95% CI: 4.70-52.83) and subglottic stenosis (SS, OR = 11.2, 95% CI: 1.85-68.02) remained significant predictors after multivariate regression.

CONCLUSION

The national prevalence of VFMI among neonates following EA and/or TEF repair was 2.3% and was associated with an increased likelihood of tracheostomy in the KID 2016. Significant predictors of in-hospital mortality were cardiac anomalies, chromosomal anomalies, extreme prematurity, and BW < 1.5 kg. BPD and SS were significant predictors of tracheostomy, and BPD and BW < 1.5 kg were significant predictors for G-tube requirements.

Thoracoscopy versus thoracotomy for esophageal atresia and tracheoesophageal fistula: Outcomes from the Midwest Pediatric Surgery Consortium

BACKGROUND/PURPOSE

Controversy persists regarding the ideal surgical approach for repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We examined complications and outcomes of infants undergoing thoracoscopy and thoracotomy for repair of Type C EA/TEF using propensity score-based overlap weights to minimize the effects of selection bias.

METHODS

Secondary analysis of two databases from multicenter retrospective and prospective studies examining outcomes of infants with proximal EA and distal TEF who underwent repair at 11 institutions was performed based on surgical approach. Regression analysis using propensity score-based overlap weights was utilized to evaluate outcomes of patients undergoing thoracotomy or thoracoscopy for Type C EA/TEF repair.

RESULTS

Of 504 patients included, 448 (89%) underwent thoracotomy and 56 (11%) thoracoscopy. Patients undergoing thoracoscopy were more likely to be full term (37.9 vs. 36.3 weeks estimated gestational age, p < 0.001), have a higher weight at operative repair (2.9 vs. 2.6 kg, p < 0.001), and less likely to have congenital heart disease (16% vs. 39%, p < 0.001). Postoperative stricture rate did not differ by approach, 29 (52%) thoracoscopy and 198 (44%) thoracotomy (p = 0.42). Similarly, there was no significant difference in time from surgery to stricture formation (p > 0.26). Regression analysis using propensity score-based overlap weighting found no significant difference in the odds of vocal cord paresis or paralysis (OR 1.087 p = 0.885), odds of anastomotic leak (OR 1.683 p = 0.123), the hazard of time to anastomotic stricture (HR 1.204 p = 0.378), or the number of dilations (IRR 1.182 p = 0.519) between thoracoscopy and thoracotomy.

CONCLUSION

Infants undergoing thoracoscopic repair of Type C EA/TEF are more commonly full term, with higher weight at repair, and without congenital heart disease as compared to infants repaired via thoracotomy. Utilizing propensity score-based overlap weighting to minimize the effects of selection bias, we found no significant difference in complications based on surgical approach. However, our study may be underpowered to detect such outcome differences owing to the small number of infants undergoing thoracoscopic repair.

Considerations of single-lung ventilation in neonatal thoracoscopic surgery with cardiac arrest caused by bilateral pneumothorax: A case report

BACKGROUND

Tension pneumothorax of the contralateral lung during single-lung ventilation (SLV) combined with artificial pneumothorax can cause cardiac arrest due to bilateral pneumothorax. If not rapidly diagnosed and managed, this condition can lead to sudden death. We describe the emergency handling procedures and rapid diagnostic methods for this critical emergency situation.

CASE SUMMARY

We report a case of bilateral pneumothorax in a neonatal patient who underwent thoracoscopic esophageal atresia and tracheoesophageal fistula repair under the combined application of SLV and artificial pneumothorax. The patient suffered sudden cardiac arrest and received emergency treatment to revive her. The recognition of dangerous vital sign parameters, rapid evacuation of the artificial pneumothorax, and initiation of lateral position cardiopulmonary resuscitation while simultaneously removing the endotracheal tube to the main airway are critically important. Moreover, even though the sinus rhythm was restored, the patient’s continued tachycardia, reduced pulse pressure, and depressed pulse oximeter waveform were worrisome. We should highly suspect the possibility of pneumothorax and use rapid diagnostic methods to make judgment calls. Sometimes thoracoscopy can be used for rapid examination; if the mediastinum is observed to be shifted to the right, it may indicate tension pneumothorax. This condition can be immediately relieved by needle thoracentesis, ultimately allowing the safe completion of the surgical procedure.

CONCLUSION

Bilateral pneumothorax during SLV combined with artificial pneumothorax is rare but can occur at any time in neonatal thoracoscopic surgery. Therefore, anesthesiologists should consider this possibility, be alert, and address this rare but critical complication in a timely manner.

An overview of esophageal atresia and tracheoesophageal fistula

ABSTRACT

Esophageal atresia and tracheoesophageal fistula are often-concomitant pathologies that primarily afflict neonates. The complications of these anomalies may lead to increased morbidity and mortality, and clinicians should be familiar with the diagnosis and management of these pathologies. Clinicians can improve patient outcomes by having a thorough understanding of the signs and symptoms, classification systems, diagnostic workup, and surgical intervention options for these patients. Early recognition and treatment are imperative in providing patients with the best opportunity for recovery.

Association of operative approach with outcomes in neonates with esophageal atresia and tracheoesophageal fistula

PURPOSE

We sought to evaluate the impact of thoracoscopic repair on perioperative outcomes in infants with esophageal atresia and tracheoesophageal fistula (EA/TEF).

METHODS

The American College of Surgeons National Surgical Quality Improvement Program pediatric database from 2014 to 2018 was queried for all neonates who underwent operative repair of EA/TEF. Operative approach based on intention to treat was correlated with perioperative outcomes, including 30-day postoperative adverse events, in logistic regression models.

RESULTS

Among 855 neonates, initial thoracoscopic repair was performed in 133 (15.6%) cases. Seventy (53%) of these cases were converted to open. Those who underwent thoracoscopic repair were more likely to be full-term (p = 0.03) when compared to those in the open repair group. There were no significant differences in perioperative outcome measures based on surgical approach except for operative time (thoracoscopic: 217 min vs. open: 180 min, p<0.001). A major cardiac comorbidity (OR 1.6, 95% CI 1.2-2.1; p = 0.003) and preoperative ventilator requirement (OR 1.4, 95% CI 1.0-1.9; p = 0.034) were the only risk factors associated with adverse events.

CONCLUSIONS

Thoracoscopic neonatal repair of EA/TEF continues to be used sparingly, is associated with high conversion rates, and has similar perioperative outcomes when compared to open repair.

Clinical comparison between thoracoscopic and thoracotomy repair of Gross type C esophageal atresia

Background

To compare the clinical outcomes between thoracoscopic approach and thoracotomy surgery in patients with Gross type C Esophageal atresia (EA) and tracheoesophageal fistula (TEF).

Methods

Patients with Gross type C EA/TEF who underwent surgery from January 2007 to January 2020 at Beijing Children’s Hospital were retrospectively analyzed. The patients were divided into two groups according to surgical approaches. The perioperative factors and postoperative complications were compared among the two groups.

Results

One hundred and ninety patients (132 boys and 58 girls) with a median birth weight of 2975 (2600, 3200) g were included. The primary operations were performed via thoracoscopic (n = 62) and thoracotomy (n = 128) approach. After comparison of clinical characteristics between the two groups, we found that there were statistically significant differences in associated anomalies, method of fistula closure, duration of mechanical ventilation after surgery, feeding option before discharge, management of pneumothorax, and prognosis (all P < 0.05). To a certain extent, thoracoscopic surgery reduced the incidence of anastomotic leakage and increased the incidence of anastomotic stricture in this study. However, there were no statistically significant differences between the two groups in terms of operative time, postoperative pneumothorax, anastomotic leakage, anastomotic stricture, and recurrent tracheoesophageal fistula (all P > 0.05).

Conclusions

Thoracoscopy surgery for Gross type C EA/TEF is a safe and effective, minimally invasive technique with comparable operative time and incidence of postoperative complications.

Anesthesia for thoracic surgery in infants and children

The management of infants and children presenting for thoracic surgery poses a variety of challenges for anesthesiologists. A thorough understanding of the implications of developmental changes in cardiopulmonary anatomy and physiology, associated comorbid conditions, and the proposed surgical intervention is essential in order to provide safe and effective clinical care. This narrative review discusses the perioperative anesthetic management of pediatric patients undergoing noncardiac thoracic surgery, beginning with the preoperative assessment. The considerations for the implementation and management of one-lung ventilation (OLV) will be reviewed, and as will the anesthetic implications of different surgical procedures including bronchoscopy, mediastinoscopy, thoracotomy, and thoracoscopy. We will also discuss pediatric-specific disease processes presenting in neonates, infants, and children, with an emphasis on those with unique impact on anesthetic management.

Surgical treatment of esophageal atresia with lower tracheoesophageal fistula in an extremely preterm infant (510 g, 25 + 5 weeks): a case report

Background

The surgical management of esophageal atresia in extreme-low-birth-weight infants (< 1000 g) is challenging. We report on an extreme-low-birth-weight infant who was extremely preterm (510 g, 25 + 5 weeks) and of prenatally unknown Gross type C esophageal atresia.

Case presentation

After resuscitation and intubation, the tracheoesophageal fistula was closed on the first day of life in the neonatal intensive care unit via an extrapleural approach using a titanium clip. On the sixth day of life, the Caucasian child was extubated. To minimize the operative trauma in the initial neonatal period, we prolonged gastrostomy placement until the 22nd day of life (weight 725 g). At the age of 3 months (weight 2510 g), thoracoscopic esophageal anastomosis was performed. The postoperative course was unremarkable. During the further clinical course, eight esophageal dilations were necessary. Currently, the patient swallows without difficulties at the age of 4 years and thrives well [15 kg (Percentile 28); 100 cm (Percentile 24)].

Conclusions

Our case shows that minimized postnatal surgical trauma with primary tracheoesophageal fistula closure at the bedside, delayed gastrostomy, and minimally invasive esophageal repair after substantial weight gain (> 2.5 kg) is a good strategy for esophageal atresia/tracheoesophageal fistula in extreme-low-birth-weight infants.

Video-Assisted Thoracoscopic or Conventional Thoracic Surgery in Infants and Children: Current Evidence

INTRODUCTION

 The pros and cons of video-assisted thoracoscopic versus conventional thoracic surgery in infants and children are still under debate. We assessed reported advantages and disadvantages of video-assisted thoracoscopy in pediatric surgical procedures, as well as the evidence level of the available data.

MATERIALS AND METHODS

 A systematic literature search was performed to identify manuscripts comparing video-assisted thoracoscopic and the respective conventional thoracic approach in classic operative indications of pediatric surgery. Outcome parameters were analyzed and graded for level of evidence (according to the Oxford Centre of Evidence-Based Medicine).

RESULTS

 A total of 48 comparative studies reporting on 12,709 patients, 11 meta-analyses, and one pilot randomized controlled trial including 20 patients were identified. More than 15 different types of advantages for video-assisted thoracoscopic surgery were described, mostly with a level of evidence 3b or 3a. Most frequently video-assisted thoracoscopic surgery was associated with shorter hospital stay, shorter postoperative ventilation, and shorter time to chest drain removal. Mortality rate and severe complications did not differ between thoracoscopic and conventional thoracic pediatric surgery, except for congenital diaphragmatic hernia repair with a lower mortality and higher recurrence rate after thoracoscopic repair. The most frequently reported disadvantage for video-assisted thoracoscopic surgery was longer operative time.

CONCLUSION

 The available data point toward improved recovery in pediatric video-assisted thoracoscopic surgery despite longer operative times. Further randomized controlled trials are needed to justify the widespread use of video assisted thoracoscopy in pediatric surgery.

Successful thoracoscopic treatment for tracheoesophageal fistula and esophageal atresia of communicating bronchopulmonary foregut malformation group IB with dextrocardia: a case report of VACTERL association

Background

A communicating bronchopulmonary foregut malformation (CBPFM) group IB is very rare congenital malformation. Group IB is associated with tracheoesophageal fistula and esophageal atresia (TEF-EA) and a portion of one lung arisen from the esophagus (Gerle et al. in N Engl J Med. 278:1413–1419, 1968). The coexistence of TEF-EA and dextrocardia is also a rare and challenging setting for repair of TEF-EA. Therefore, the thoracoscopic surgery for TEF-EA require the technical devise because of the small operative space. We herein report a rare case of CBPFM group IB with intralobar sequestration of lung and a successful performing of thoracoscopic surgery for EA with dextrocardia in VACTERL association.

Case presentation

A 2.2-kg term male neonate was born with an anal atresia, coarctation of the aorta, TEF-EA, renal anomalies, radial hemimelia, limb abnormalities (VACTERL association) and hypoplasia of the right lung with dextrocardia. The patient developed respiratory distress after admission. A two-stage operation for the TEF-EA was planned because of multiple anomalies and cardiac condition. In the neonatal period, esophageal banding at the gastroesophageal junction and gastrostomy were performed to establish enteral nutrition. After gaining body weight and achieving a stable cardiac condition, thoracoscopic surgery for TEF-EA was performed. The thoracoscopic findings revealed a small working space due to dextrocardia. To obtain a sufficient working space and to perform secure esophageal anastomosis, an additional 3-mm assistant port was inserted. To close the upper and lower esophagus, anchoring sutures of the esophagus were placed and were pulled to suspend the anastomotic site. Esophageal anastomosis was successfully performed. An esophagogram after TEF-EA surgery showed the connection between the lower esophagus and right lower lung. The definitive diagnosis was CBPFM group IB with intralobar sequestration. The thoracoscopic surgery was performed again for establishing oral intake. After transection of the bronchoesophageal fistula, the patient could perform oral feeding without pneumonia or respiratory distress.

Conclusions

CBPFM type IB with intralobar sequestration is a rare condition. CBPFM type IB should be considered for a patients with respiratory symptom after radical operation for TEF-EA. In the present case, suspending the anastomotic site was effective and useful in thoracoscopic surgery for a TEF-EA patient with dextrocardia.

Thoracoscopic Esophageal Atresia Repair: Outcomes Analysis Between Primary and Staged Procedures

PURPOSE

Thoracoscopic repair of esophageal atresia (EA) is analyzed in this systematic review that compares outcomes between primary and staged repairs.

MATERIALS AND METHODS

PubMed/Embase databases were reviewed for articles on thoracoscopic repair of EA, and articles were selected for primary and staged repairs. Descriptive statistics were used to analyze the quantitative parts of the study.

RESULTS

Thirty-six articles identified between 1999 and 2019 met the inclusion criteria and offered 776 patients for this analysis. Primary repairs were performed in n=703 and staged repairs in n=73. Comparative analysis showed that esophageal anastomosis was performed using absorbable suture in 88% primary and 78% staged repairs. Anastomotic leak rates were comparable between primary n=65/696 (9%) and staged repairs n=8/73 (11%). The re-fistulation rate was 2% in primary and 1% in staged repairs. There was no difference between suture material and re-fistulation (P>0.05; NS). In primary repairs, nonabsorbable sutures were found to be associated with more leaks than absorbable sutures (P<0.05*). The conversion rate was similar between 2 approaches; primary n=49/680 (7%) and staged n=6/73 (8%); P>0.05. No significant differences were found in the rate of anastomosis strictures between primary n=135/703 (19%) and staged repair n=21/73 (29%); P>0.05. The overall mortality was n=20/703 (3%) in primary and n=1/73 (1%) in staged repairs; P>0.05.

CONCLUSIONS

Successful thoracoscopic primary- and staged-EA repairs have been reported with low rate of complications. Outcomes between primary and staged repairs do not show significant differences with regards to re-fistulation, anastomotic leaks, conversion rates, and mortality.

Experience of Minimally Invasive Surgery in Neonates with Congenital Malformations in a Tertiary Care Pediatric Hospital

Aim:

The aim of this study is to report the experience with minimally invasive surgery (MIS) in neonates with congenital malformations in a tertiary care pediatric hospital.

Materials and Methods:

Design: descriptive study. All neonates undergoing MIS from 2013 to 2018 were included in the study. Perinatal data, characteristics of surgery, type and duration of analgesia, postoperative mechanical ventilation duration, postoperative hospitalization, and postoperative morbidity and mortality surgery-related rates were recorded.

Results:

Seventy-one neonates were included. Gestational age and weight at surgery ranged from 24 to 41 weeks and from 1350 g to 4830 g, respectively. Procedures performed were esophageal atresia/tracheoesophageal fistula repair, congenital diaphragmatic hernia repair, diaphragmatic plication, fundoplication/gastrostomy, intestinal atresia repair, and pancreatectomy. The median follow-up period was 14 months. Five neonates (7%) were converted to open, for surgical difficulties. Nine (12.6%) neonates had intraoperative complications, with decreased oxygen saturation as the most common complication. The median duration of analgesia and postoperative mechanical ventilation was 3 days in most procedures. The morbidity and mortality rates were 36.6% and 2.8%, respectively.

Conclusions:

In this first experience with MIS in neonates, the duration of analgesia and hospitalization was shorter for some procedures. However, intraoperative and postoperative complications were still high, which was possibly attributed to the learning curve. Thus, it is expected that the frequency of the complications presented in this study will be reduced in future.

Thirty Years of Minimally Invasive Surgery in Children: Analysis of Meta-Analyses

INTRODUCTION

 In the last three decades, minimally invasive surgery (MIS) has been widely used in pediatric surgery. Meta-analyses (MAs) showed that studies comparing minimally invasive with the corresponding open operations are available only for selected procedures. We evaluated all available MAs comparing MIS with the corresponding open procedure in pediatric surgery.

MATERIALS AND METHODS

 A literature search was performed on all MAs listed on PubMed. All analyses published in English, comparing pediatric minimally invasive with the corresponding open procedures, were included. End points were advantages and disadvantages of MIS. Results of 43 manuscripts were included. MAs evaluating the minimally invasive with the corresponding open procedures were available for 11 visceral, 4 urologic, and 3 thoracoscopic types of procedures. Studies included 34 randomized controlled trials. In 77% of MAs, at least one advantage of MIS was identified. The most common advantages of MIS were a shorter hospital stay in 20, a shorter time to feeding in 11, and a lower complication rate in 7 MAs. In 53% of MAs, at least one disadvantage of MIS was found. The most common disadvantages were longer operation duration in 16, a higher recurrence rate of diaphragmatic hernia in 4, and gastroesophageal reflux in 2 MAs. A lower native liver survival rate after laparoscopic Kasai-portoenterostomy was reported in one MA.

CONCLUSION

 In the available MAs, the advantages of MIS seem to outnumber the disadvantages. However, for some types of procedures, MIS may have considerable disadvantages. More randomized controlled trials are required to confirm the advantage of MIS for most procedures.

Thoracoscopic versus conventional open repair of tracheoesophageal fistula in neonates: A short-term comparative study

PURPOSE

Esophageal atresia with or without a tracheo-esophageal fistula is a challenging anomaly in neonates. Thoracoscopic repair is gaining popularity now in pediatric surgery community. The present study aims at comparing the short term outcomes of thoracoscopy versus classic thoracotomy for repair of such conditions.

METHODS

Thirty neonates with tracheoesophageal fistula were randomly divided into two equal groups (n=15) after excluding patients with birth weight <2000g, multiple associated anomalies and cardiorespiratory instability. One group had conventional open repair while the other had thoracoscopic repair. Demographic data, intraoperative result and post-operative findings were recorded and compared between both groups.

RESULTS

Both groups showed similar results regarding demographic and patients' characteristics. Thoracoscopic repair had relatively longer, yet non-significant operative time but with highly significant difference in preserving azygos vein. There was low conversion rate with thoracoscopy (6.66%). Open repair resulted in a longer hospital stay (11.73±5.68 vs 9.2±2.95). Complication rate was comparable in both groups; however, thoracoscopy was associated with better cosmetic results as reported by parents and surgeons (p=0.00).

CONCLUSION

Compared to thoracotomy, thoracoscopic repair offers a less invasive, effective and safe technique with similar short term outcomes, but with superior cosmetic results and better ability to spare azygos vein.

Is thoracoscopic esophageal atresia repair safe in the presence of cardiac anomalies?

BACKGROUND

Esophageal atresia (EA) is often associated with congenital heart disease (CHD). Repair of EA by the thoracoscopic approach places physiological stress on a newborn with CHD. This paper reviews the outcomes of infants with CHD who had undergone thoracoscopic EA repair, comparing their outcomes to those without CHD.

METHODS

This was a review of infants who underwent thoracoscopic EA repair from 2009 to 2017 at one institution. Operative time and outcomes were analyzed in relation to CHD status.

RESULTS

Twenty five infants underwent thoracoscopic EA repair during the study period. Seventeen (68%) had associated anomalies of whom 9 (36%) had cardiac anomalies. The mean operative time was 217 min. There was no difference in operative time between CHD and non-CHD cases (estimate 20 min longer operative time in the presence of a cardiac anomaly [95% CI -20 to 57]). Two cases were converted to open thoracotomy; both were non-CHD. There was no difference in the time to feeding, time in intensive care unit or time in hospital between CHD and non-CHD cases. Five patients developed an anastomotic leak (two CHD and three non-CHD) of which two were clinical; all were managed conservatively. There was no case of recurrent fistula.

CONCLUSIONS

This pilot study did not find evidence that thoracoscopic EA repair compromised outcomes in children with congenital heart disease. A prospective multicenter study with long-term follow-up is recommended to confirm whether thoracoscopic repair in CHD is truly equivalent to the open operation.

Thoracoscopic approach for complications after esophageal atresia repair: initial experience

INTRODUCTION

Improvements in technology and health care have helped reduce morbidity and mortality in patients with esophageal atresia. However, postoperative complications such as dehiscences, strictures, and recurrent fistulas still occur in a large percentage of patients. Here, we present our initial experience using the thoracoscopic approach for complications after esophageal atresia repair.

METHODS

We retrospectively analyzed the medical records of patients who developed complications after esophageal atresia repair and underwent thoracoscopic reoperation at two centers. Anastomotic leakage, anastomotic stricture, and recurrent tracheoesophageal fistula were assessed as complications after esophageal atresia repair.

RESULTS

We reoperated on four patients (range of age 3 days - 2 years) by thoracoscopy. Two patients who had undergone thoracoscopic atresia repair presented with anastomotic dehiscence. The anastomoses were thoracoscopically reconstructed without tension. One patient had undergone thoracoscopic atresia repair presented with esophageal stricture refractory to endoscopic dilatations. Thoracoscopic esophagoesophagostomy was performed in this 2-year-old patient. One patient who had undergone esophageal atresia repair and tracheoesophageal fistula closure by thoracotomy presented with a recurrent fistula at 1 year of age. The patient underwent thoracoscopic fistula closure with a 5-mm endostapler. All patients remain asymptomatic after reoperation.

CONCLUSIONS

Reoperation after esophageal atresia repair is challenging and carries a relatively high risk of developing complications. Compared to conventional surgery, the thoracoscopic approach in experienced hands offers better visualization and more accurate dissection and drainage of the thoracic cavity. Therefore, we want to encourage the use of thoracoscopy in the treatment of complications after esophageal atresia repair.

Outcome of thoracoscopic repair of type-C esophageal atresia: a single-center experience from North Africa

Thoracoscopic repair of esophageal atresia is gaining popularity worldwide attributable to availability and advances in minimally invasive instruments. In this report, we presented our experience with thoracoscopic esophageal atresia/tracheoesophageal fistula (EA/TEF) repair in our tertiary care institute. A prospective study on short-gap type-C EA/TEF was conducted at Cairo University Specialized Pediatric Hospital between April 2016 and 2018. Excluded were cases with birth weight < 1500 gm, inability to stabilize physiologic parameters, or major cardiac anomalies. The technique was standardized in all cases and was carried out by operating team concerned with minimally invasive surgery at our facility. Primary outcome evaluated was successful primary anastomosis. Secondary outcomes included operative time, conversion rate, anastomotic leakage, recurrent fistula, postoperative stricture, and time till discharge. Over the inclusion period of this study, 136 cases of EA/TEF were admitted at our surgical NICU. Thoracoscopic repair was attempted in 76 cases. In total, 30 cases were pure atresia/long gap type-C atresia and were excluded from the study. Remaining 46 cases met the inclusion criteria and were enrolled in the study. Mean age at operation was 8.7 days (range 2-32), and mean weight was 2.6 Kg (range 1.8-3.6). Apart from five cases (10.8%) converted to thoracotomy, the mean operative time was 108.3 minutes (range 80-122 minute). A tension-free primary anastomosis was possible in all thoracoscopically managed cases (n = 41) cases. Survival rate was 85.4% (n = 35). Anastomotic leakage occurred in seven patients (17%). Conservative management was successful in two cases, while esophagostomy and gastrostomy were judged necessary in the other for five. Anastomotic stricture developed in five cases (16.6%) of the 30 surviving patients who kept their native esophagus. Despite the fact that good mid-term presented results may be due to patient selection bias, thoracoscopic approach proved to be feasible for management of short-gap EA/TEF. Authors of this report believe that thoracoscopy should gain wider acceptance and pediatric surgeons should strive to adopt this procedure.

Thoracoscopy vs. thoracotomy for the repair of esophageal atresia and tracheoesophageal fistula: a systematic review and meta-analysis

Esophageal atresia (EA) and tracheoesophageal fistula (TEF) require emergency surgery in the neonatal period to prevent aspiration and respiratory compromise. Surgery was once exclusively performed via thoracotomy; however, there has been a push to correct this anomaly thoracoscopically. In this study, we compare intra- and post-operative outcomes of both techniques. A systematic review and meta-analyses was performed. A search strategy was developed in consultation with a librarian which was executed in CENTRAL, MEDLINE, and EMBASE from inception until January 2017. Two independent researchers screened eligible articles at title and abstract level. Full texts of potentially relevant articles were then screened again. Relevant data were extracted and analyzed. 48 articles were included. A meta-analysis found no statistically significant difference between thoracoscopy and thoracotomy in our primary outcome of total complication rate (OR 0.98, [0.29, 3.24], p = 0.97). Likewise, there were no statistically significant differences in anastomotic leak rates (OR 1.55, [0.72, 3.34], p = 0.26), formation of esophageal strictures following anastomoses that required one or more dilations (OR 1.92, [0.93, 3.98], p = 0.08), need for fundoplication following EA repair (OR 1.22, [0.39, 3.75], p = 0.73)-with the exception of operative time (MD 30.68, [4.35, 57.01], p = 0.02). Considering results from thoracoscopy alone, overall mortality in patients was low at 3.2% and in most cases was due to an associated anomaly rather than EA repair. Repair of EA/TEF is safe, with no statistically significant differences in morbidity when compared with an open approach.Level of evidence 3a systematic review of case-control studies.

Harlequin Syndrome after Thoracoscopic Repair of a Child with Tracheoesophageal Fistula (TEF)

Harlequin syndrome (HS) is a rare dysautonomia of the sympathetic nervous system leading to asymmetric facial flushing and sweating. In the literature, only a few cases of HS after thoracoscopic tracheoesophageal fistula (TEF) repair are reported. We report on a newborn with TEF who developed HS after thoracoscopic repair. On the first day of life, the girl (3,480 g, gestation age: 41 week) underwent thoracoscopic repair of a type C esophageal atresia (TEF; OR time 105 minute) without complications. The postoperative course was uneventful, the patient swallowed and thrived well and did not require esophageal dilatations. At 2 years of age, missing facial flushing, transpiration, and warming on the right side of her face during agitation were noticed. As no further intervention was required, the girl and her parents adapted well to the symptoms. Our report shows that the late onset of HS after the surgical procedure is unlikely a direct causal relation to the thoracoscopic operation but rather a shared embryological pathogenesis, like a neurocristopathy.

Impact of congenital heart disease on outcomes after primary repair of esophageal atresia: a retrospective observational study using a nationwide database in Japan

PURPOSE

To verify the association between congenital heart disease (CHD) and postoperative complications after primary repair of esophageal atresia in patients from a Japanese nationwide database.

METHODS

We identified babies in the Diagnosis Procedure Combination database who underwent radical surgery for esophageal atresia from 2010 to 2016. We used multivariable logistic regression analyses to evaluate the occurrence of anastomotic leakage and anastomotic stricture.

RESULTS

Among 431 patients who underwent primary anastomosis, 114 patients (27%) had CHD. Anastomotic leakage occurred in 77 patients (17.9%) and stricture in 154 (35.7%). Compared with patients whose anesthetic duration was less than 240 min, those with anesthesia lasting from 240 to 360 min (odds ratio 2.49; 95% confidence interval (CI) 1.17-5.27; p = 0.02) or more than 360 min (odds ratio 4.10; 95% CI 1.69-9.96; p = 0.002) were more likely to experience anastomotic leakage. Male patients had a lower risk of anastomotic stricture than female patients (odds ratio 0.65; 95% CI 0.43-0.9; p = 0.04).

CONCLUSIONS

CHD was not associated with anastomotic leakage or stricture. The only significant predictor of anastomotic leakage was duration of anesthesia.

A multicenter audit of the use of bronchoscopy during open and thoracoscopic repair of esophageal atresia with tracheoesophageal fistula

BACKGROUND

Esophageal atresia (EA) with tracheoesophageal fistula is usually repaired in the neonatal period. Preferential ventilation through the fistula can lead to gastric distension. Bronchoscopy has a role in defining the site and size of the fistula, and may be carried out by the surgeon or the anesthetist. The use of bronchoscopy varies across different institutions.

METHODS

This is a multicenter case note review of infants with EA with tracheoesophageal fistula who underwent surgery between January 2010 and December 2015. This retrospective audit aims primarily to document the use of bronchoscopy during open and thoracoscopic repair at a selection of United Kingdom centers. Respiratory complications, that is relating to airway management, the respiratory system, and difficulty with ventilation, at induction and during surgery, are recorded. The range of techniques for anesthesia and analgesia in these centers is noted.

RESULTS

Bronchoscopy was carried out in 52% of cases. The incidence of respiratory complications was 7% at induction and 21% during surgery. Thoracoscopic repair usually took longer. One center used high-frequency oscillatory ventilation, on an elective basis during thoracoscopic repair, to facilitate surgical access and address concerns about hypoxemia and hypercarbia.

CONCLUSION

The use of bronchoscopy varies considerably between institutions. Infants undergoing tracheoesophageal fistula repair are at risk of perioperative respiratory morbidity. The advent of thoracoscopic repair has introduced further variation.

Thoracoscopic esophagoesophagostomy for a refractory stricture in a patient with esophageal atresia

Anastomosis stricture is a well-known complication after esophageal atresia repair. Endoscopic dilatation is the gold standard treatment for esophageal stenosis. However, surgical interventions are indicated for refractory cases. We present a 2-year-old girl with esophageal stricture refractory to regular endoscopic dilatation after esophageal atresia repair that underwent thoracoscopic stricture resection and reanastomosis. Although thoracoscopic approach is widely used for esophageal atresia repair, this approach has not been used before for the treatment of anastomosis stricture.

Esophageal atresia, Europe, and the future: BAPS Journal of Pediatric Surgery Lecture

Europe has changed remarkably over the past decades and so have concepts and outcomes of esophageal atresia repair. In this article, both the efforts to create a united Europe and the achievements in dealing with esophageal atresia from the 1950s on are outlined. Furthermore, this paper deals with the future of pediatric surgery and is focused on two aspects: the "Fourth Industrial Revolution" which builds on the digital revolution, artificial intelligence and robotics, and its potential impact on pediatric surgery and the life of patients. I suggest that pediatric surgeons should participate and lead in the development of machine learning, data control, assuring appropriate use of machines, control misuse, and in particular ensure appropriate maintenance of ethical standards. Changes in health care structures within Europe, in particular the effect of centralization, will affect the concept of treatment for patients with rare diseases.

Thoracoscopy in pediatrics: Surgical perspectives

Thoracoscopic surgery and other minimally invasive approaches in children achieved marked advancement and expanded to include several disciplines in the last decade. The new armamentarium of the minimally invasive surgery including the smaller instruments and better magnification led to the application of this technology in the small infants and neonates. Currently, thoracoscopy is considered the preferred surgical approach for various conditions in neonates and infants over the standard thoracotomy, and thoracoscopic training is included in the surgical training curriculum for the residents in many institutes worldwide. Children are different from adults, and technique modifications are required when using thoracoscopy in children. Thoracoscopy showed satisfactory results in several operations including pulmonary resections, mediastinal tumors biopsies or resections, repair of the diaphragmatic hernias, decortication, and tracheoesophageal fistula. This review aims to address the unique aspects of thoracoscopic surgery in children, identify its potential technical and anatomical challenges, and the proposed solutions. A literature search for latest and relevant publications was done using the keywords (thoracoscopy; pediatric; lung biopsy; decortication; lobectomy; mediastinum; esophagus; and diaphragmatic hernia).
