BACKGROUND: Esophageal atresia (EA) is a life-threatening congenital malformation in newborns, and the traditional repair approaches pose technical challenges and are extremely invasive. Therefore, surgeons have been actively investigating new minimally invasive techniques to address this issue. Magnetic compression anastomosis has been reported in several studies for its potential in repairing EA. In this paper, the primary repair of EA with magnetic compression anastomosis under thoracoscopy was reported.
METHODS: A full-term male weighing 3500 g was diagnosed with EA gross type C. The magnetic devices used in this procedure consisted of two magnetic rings and several catheters. Tracheoesophageal fistula ligation and two purse strings were performed. The magnetic compression anastomosis was then completed thoracoscopically. After the primary repair, no additional operation was conducted. A patent anastomosis was observed on the 15th day postoperatively, and the magnets were removed on the 23rd day. No leakage existed when the transoral feeding started.
CONCLUSIONS: Thoracoscopic magnetic compression anastomosis may be a promising minimally invasive approach for repairing EA.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a developmental defect that causes herniation of abdominal organs into the thoracic cavity with significant morbidity. Thoracoscopic repair of CDH is an increasingly prevalent yet controversial surgical technique, with limited long-term outcome data in the Asian region. The aim of this study was to compare open laparotomy versus thoracoscopic repair of CDH in paediatric patients in a major tertiary referral centre in Asia.
METHODS: We performed a retrospective analysis of neonatal patients who had open laparotomy or thoracoscopic repair for CDH in our institution between July 2002 and November 2021. Demographic data, perioperative parameters, recurrence rates and surgical complications were analysed.
RESULTS: 64 patients were identified, with 54 left sided CDH cases. 33 patients had a prenatal diagnosis and 35 patients received minimally invasive surgical repair. There was no significant difference between open and minimally invasive repair in recurrence rate (13 % vs 17 %, P = 0.713), time to recurrence (184 ± 449 days vs 81 ± 383 days, P = 0.502), or median length of ICU stay (11 ± 14 days vs 13 ± 15 days, P = 0.343), respectively. Gastrointestinal complications occurred in 7 % of neonates in the open group and none in the thoracoscopic group. Median follow-up time was 9.5 years.
CONCLUSIONS: This study is a large congenital diaphragmatic hernia series in Asia, with long term follow-up demonstrating no significant difference in recurrence rate, time to recurrence or median length of ICU stay between open and minimally invasive repair, suggesting thoracoscopic approach is a non-inferior surgical option with avoidance of gastrointestinal complications compared to open repair.

METHODS: Retrospective Cohort Study.

Introduction: Esophageal atresia (EA) is a rare defect in the continuity of the esophagus, with the absent portion forming an upper and lower segment. Despite both thoracoscopic and conventional open repair (OR) techniques being well established worldwide, the literature remains unclear as to the comparison of surgical outcomes and efficacy of each procedure. Aim: To conduct a systematic review to determine which technique for EA repair, thoracoscopic or open, has the better outcome. Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) compliant literature search returned 14 full text articles for analysis of demographic information and surgical outcomes. Results: Major comorbidities were more likely in the OR group (P < .05) with all other surgical outcomes comparable between the two groups. Conclusion: Overall, this systematic review highlights that the surgical outcomes of patients undergoing thoracoscopic repair for EA are comparable with those of the conventional OR.

The frequency rate of esophageal anastomosis leaks after thoracoscopic correction of esophageal atresia (EA) in the current literature is reported as 5.6%-24.7% and a conversion rate of 2%-53%. The objective of this retrospective study was to examine the characteristics of EA and analysis of the safety and efficacy of EA repair with the use of the thoracoscopic approach in a single academic center, as well as risk factors analysis in the context of short-term and mid-term follow-up status. A retrospective analysis of the management of all consecutive newborns affected by EA hospitalized in our department over a period between 2013 and 2022, including preoperative, perioperative, and postoperative management, together with the outcome, complications and long-term follow-up status was performed. A total of 38 patients with a median birth weight of 2,570 g (range; 1,020-3,880) were treated over the study period, including 30/38 (78.9%) with additional congenital anomalies. Overall, 30 patients underwent primary anastomosis of the esophagus and eight underwent a multistaged procedure, with or without an initial ligation of the tracheoesophageal fistula and delayed primary anastomosis. Overall survival for all patients was 0.894 ± 0.050, with a median follow-up of 4.5 years. We noted neither anastomotic leaks nor conversions to open technique in our cohort. Implementation of vancomycin prophylaxis was successful in preventing postoperative central venous access-related infectious complications. At the end of the follow-up, 85% of patients have a Lansky performance score ≥80. Risk factors analysis for length of hospitalization, overall survival, Lansky performance status, and neurological impairment were analyzed. In conclusion, we have found that the outcome of thoracoscopic repair of EA in terms of surgery-dependent morbidity (anastomosis leakage, conversion rate to open surgery), provides benefit to those previously reported in the literature, regardless of the prognostic criteria of the classification system.

Introduction: Surgical intervention is the definitive management for congenital diaphragmatic hernia (CDH) repair from 1902. Since this time, two mainstay approaches have been used, open and minimally invasive surgical (MIS) repair. An invasive laparotomy is used in around 91% of cases. So, this systematic review of the published literature will compare the surgical outcomes of open (CDH) repair vs MIS for CDH repair and will determine which approach is superior. Material and Methods: Our literature search across MEDLINE and EMBASE included articles from 2004 to 2022, incorporating pediatric CDH repairs, human subjects only, and English language articles. Primary outcomes analyzed were rate of recurrence, length of surgery, length of hospital stay, use of diaphragmatic patch, mortality, postoperative chylothorax, and extracorporeal membrane oxygenation (ECMO) use postoperatively. Results: After application of exclusion criteria, 32 articles were reviewed. Comparison of MIS repair versus open repair had a rate of recurrence at 8.6% versus 1.6% (P < .00001). Length of hospital stay was 19.6 days versus 33.6 days (P = .0012), mortality rate at 4.6% versus 16.6% (P < .0001), patch repair required in 19.6% versus 55.4% (P = < .00001), and postoperative ECMO use of 3.7% versus 12.3% (P < .00001), respectively. Conclusion: MIS repair is associated with decreased length of hospital stay, reduced mortality rate, and postoperative ECMO usage. Hernia recurrence is still high among MIS repair groups compared to the open repair groups. Large, multicentered randomized control trials are recommended for further analysis to decipher the true superior surgical intervention.

Introduction: The treatment of long-gap esophageal atresia (LGEA) remains an important issue for pediatric surgeons. There are several methods of treating LGEA with various advantages and disadvantages. Thoracoscopic esophageal elongation using internal traction sutures has been developed more recently. Therefore, we wanted to report on our first experience in treating such pathology using staged thoracoscopic internal traction. Objective: To share our first experience in the treatment of LGEA using staged thoracoscopic internal traction. Methods: Three children with LGEA were treated at the University Medical Center \"National Scientific Center for Maternal and Child Health\" in the Pediatric Surgery Department, Nur-Sultan, Kazakhstan, using the method of staged thoracoscopic internal traction. Results: At the age of 3-4 months, 3 patients were operated on successfully using staged thoracoscopic internal traction. In any case, converting to an open thoracotomy was not needed and no anastomotic leakage was observed. In 2 cases, stenosis occurred that was treated by dilatation at least twice, 1 child had no stenosis. Conclusions: Thoracoscopic internal traction technique for LGEA was performed for the first time in Kazakhstan that showed its safety and possible future use in the surgical treatment of this congenital malformation.

UNASSIGNED: Congenital diaphragmatic hernia (CDH) is an anomaly with significant morbidity in neonates. It has been traditionally managed by an open approach with a recent trend toward a minimally invasive approach.
UNASSIGNED: This is a retrospective study of our institutional experience with neonatal thoracoscopic management of CDH, with the impact of few technical nuances.
UNASSIGNED: The data was collected on neonatal thoracoscopic CDH repair between January 2015 and December 2018, in terms of the demographics, intra-operative parameters, post-operative status, recurrence, and mortality. While analyzing data, we found few technical modifications adopted by the surgeon such as trimming the margin of the defect, use of prosthetic mesh overlay reinforcement for repairs under tension, and to prefer extra-corporeal knotting along with higher placement of trocar, temporary increase in CO2, maximal use of muscle relaxant, extra-corporeal corner hitch stitch at some point, and continuation for further cases. An internal comparison was made to analyze the technical modifications influencing the outcomes, by dividing them into two groups, those with (group A) and without modifications (group B). The data was analyzed using SPSS software (IBM, Version 23). A P value of <0.05 was considered statistically significant.
UNASSIGNED: Out of 45 newborns 64.4% were males with an average birth weight of 2.6 kg. Baseline variables were comparable between the groups. The operating time significantly reduced after a higher-level camera port was used (P-value: 0.0001). The mean follow-up was 30.8 months. There were totally seven recurrences (6 in group A and 1 in group B), all within 12 months. Seven parents gave the overall post-treatment feedback as \"unsatisfied\". The operating time, recurrence rate, and parental satisfaction feedback were significantly less in group B (P-value: 0.001).
UNASSIGNED: We recommend trimming the margin of the defect, use of prosthetic mesh overlay reinforcement for repairs under tension, and to prefer extra-corporeal knotting along with higher placement of trocar, temporary increase in CO2, maximal use of muscle relaxant, extra-corporeal corner hitch stitch to reduce the operating time, and recurrence after thoracoscopic CDH repair.

UNASSIGNED: There are several forms of relevant epi-aortic branching anomalies, and perhaps that is why different views as to the best approach have been reported. To help resolve this dilemma, we examined the unforeseen arch anomalies found at thoracoscopic repair of esophageal atresia and the outcomes.
UNASSIGNED: In a retrospective cohort, all consecutive patients who were thoracoscopically approached for esophageal atresia over a 5-year period with unforeseen aortic/epi-aortic branching were identified and grouped. Thoracoscopic views, operative interventions, and outcomes were studied.
UNASSIGNED: A total of 121 neonates were thoracoscopically approached for EA, of whom 18 cases with aberrant aortic architecture were selected. Four (3%) cases were diagnosed on a preoperative echocardiography as a right-sided aortic arch, whereas unforeseen anomalous anatomies were reported in 14 cases (11.6%): left aortic arch with an aberrant right subclavian artery (ARSA) (n = 10), right-sided aortic arch with an aberrant left subclavian artery (ALSA) (n = 3), and mirror-image right arch (n = 1). Single postoperative mortality was reported among the group with left arch and ARSA (10%), whereas all the cases with right arch and ALSA died.
UNASSIGNED: In all, 11.6% of the studied series exhibited unexpected aberrant aortic architecture, with higher complication rates in comparison to the typical thoracoscopic repairs. For EA with left aortic arch and ARSA, the primary esophageal surgery could safely be completed. Meanwhile, curtailing surgery-after ligating the TEF-to get advanced imaging is still advised for both groups with the right arch due to the significant existence of vascular rings.

Aim: To assess the severity of persistent pulmonary hypertension (PPH) in congenital diaphragmatic hernia (CDH) neonates solely using oxygenation index (OI). Study Design: A prospective study was carried out from April 2016 to March 2019, where all confirmed CDH neonates were evaluated for the possibility repair through thoracoscopic approach. The severity of PPH was assessed using OI. It is calculated using the equation: mean airway pressure (MAP) × FiO2 × 100 ÷ PaO2. Neonates having OI <5 were considered to have a mild degree of pulmonary hypertension; hence, thoracoscopic repair was offered for them. Results: Thirty-nine CDH cases met the selection criteria; therefore, they underwent thoracoscopic repair. Primary diaphragmatic repair was successfully accomplished thoracoscopically in all neonates without any perioperative complications. Conversion from thoracoscopy to open method occurred in five cases. The causes were due to difficulties encountered during repair and none was due to a pure anesthetic problem or general deterioration during thoracoscopy. Recurrence had occurred in two cases only. Conclusion: OI is a reliable subjective parameter that could be used as an adjuvant to the usually used cardiovascular and pulmonary parameters for thoracoscopic repair decision. With increasing surgical experience, a wider range of neonates may be considered for thoracoscopic CDH repair.

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.
METHODS: 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.
