Decortication with uniport video-assisted thoracoscopic surgery for empyema due to postoperative esophageal leakage: a report of two pediatric cases

BackgroundVideo-assisted thoracoscopic surgery (VATS) is considered useful for the treatment of parapneumonic empyema in children. However, thoracoscopic management of empyema due to esophageal leakage as an operative complication has not been well described in the literature.Case presentationWe successfully decorticated severe empyema using uniport VATS in 2 children (a 2-year-old boy who suffered esophageal perforation after laparoscopic anti-reflux surgery, and a 7-month-old girl who had anastomotic leakage after thoracoscopic repair of esophageal atresia). In these patients, we noticed that pleural effusion rapidly progressed to empyema and caused respiratory insufficiency due to wide-range coverage by fibrotic pleural rind that was successfully decorticated under video-assisted vision from a mini-thoracotomy, followed by spontaneous healing of the leakage.ConclusionsWe did not attempt to closely approach or try to repair the esophageal leakage. We believe that this is an important tip for these situations.

Thoracoscopic Repair for Kluth Type Ⅲb3 Esophageal Atresia and Distal TracheoesophagealFistula

IntroductionThis report aims to present our initial miniseries of successful thoracoscopic repair for esophageal atresia (EA) and distal tracheoesophageal fistula (TEF) of Kluth type Ⅲb3 in accordance with Kluth's classification. MethodsFrom January 2012 to January 2024, ten patients with Kluth type Ⅲb3 EA-TEF were treated by thoracoscopic surgery. The therapeutic methods and surgical outcomes were retrospectively reviewed. ResultsAll procedures were completed thoracoscopically without conversions. A preoperative bronchoscopy assessment was conducted in four of the cases, revealing that the fistula from the distal segment was located high on the trachea at the level of T2 vertebral. The mean age of the patients at the time of operation was 2.0 ± 0.7 d (range, 1-3 d), and the mean weight at operation was 2.6 ± 0.4 kg (range, 1.8-3.0 kg). The mean operative time (skin to skin) for the entire series was 137.0 ± 8.9 min (range, 120-150 min). Oral feeding was initiated on the postoperative day 8.0 ± 1.9 (range, 6-12 d), and the mean duration for patients after surgery was 14.0 ± 2.4 d (range, 12-20 d). The postoperative period has been uneventful with no occurrences of mortality or morbidity to date. Three cases of formatted anastomotic stricture required at least one esophageal dilation after surgery. ConclusionsPediatric surgeons should be aware of the rare variants of EA-TEF to avoid the diagnostic and management pitfalls. Patients with Kluth type Ⅲb3 EA-TEF were amenable to repair by thoracoscopic surgery.

627. LEFT THORACOSCOPIC PRIMARY REPAIR OF ESOPHAGEAL PERFORATION SECONDARY TO BOERHAAVE SYNDROME

Abstract Background With the advancement of the minimally invasive surgical techniques, more and more acute surgical conditions including esophageal perforations can be performed safely using minimally invasive surgical approach. Methods A middle aged male patient presented to our department with 3 days history of epigastric pain and vomiting. He was febrile on admission and investigation revealed the left sided esophageal perforation due to Boerhaave Syndrome with left sided pleural effusion. He underwent left thoracoscopic primary repair of esophageal perforation and wash out successfully. This is the video of the thoracoscopic primary repair of the perforation. Patient was put in the right lateral semi prone position, the area of perforation was identified by careful dissection of the pleura and repaired was performed in 2 layers. The pleura cavity was washed out with warm saline and underwater sealed chest tube drain was inserted. Results Post operatively patient was transferred to surgical intensive care unit for 1 day. Patient was kept nil by mouth with parenteral nutrition for 7 days. Contrast study was performed on post operative day 7 and started oral feeding when there was no evidence of leakage. Patient recovered and discharged well. Conclusion Thoracoscopic primary repair with wash out of spontaneous esophageal perforation secondary to Boerrhave Syndrome is challenging however it is safe and can be performed successfully. https://drive.google.com/file/d/1JTfJLV-ngUBwzMybGV4FL8EEQB-ysj9O/view

Thoracoscopic Repair of a Rare Case of Congenital Diaphragmatic Hernia with Eventration (Mixed Lesion)

ABSTRACT Congenital diaphragmatic malformations include congenital diaphragmatic hernia (CDH) and eventration of the diaphragm. The clinical presentation is variable, and the prognosis depends on multiple factors. The coexistence of CDH and diaphragmatic eventration in the same patient is extremely unusual and has not been reported previously in the literature. We report this rare association in a 3-month-old male infant who was managed successfully by minimally invasive approach.

Comparison of the Efficacy and Safety of Thoracoscopic Surgery and Conventional Open Surgery for Congenital Diaphragmatic Hernia in Neonates: A Meta-analysis

ABSTRACT Background: Thoracoscopic surgery is an increasingly popular surgical technique for the repair of congenital diaphragmatic hernias. We performed a meta-analysis to compare the efficacy, safety of thoracoscopic surgery and the conventional open surgical approach for congenital diaphragmatic hernia in neonates. Materials and Methods: A systematic search of electronic databases such as PubMed, Google, and Web of Science was performed to identify studies comparing thoracoscopic surgery and open surgery for congenital diaphragmatic hernia. A total of 6 studies with 3348 patients were found. Parameters such as operation time, hospital stay, recurrence rate, postoperative mortality, and postoperative complications were pooled and compared by meta-analysis. Results: Of the 3348 children with congenital diaphragmatic hernia included in the 6 studies, 615 underwent thoracoscopic surgery and 2733 underwent open surgery. All studies were nonrandomized controlled trials. The operation times were shorter for thoracoscopic surgery than for open surgery in three studies, but there was no significant difference (standard mean difference = 1.25, confidence interval [CI] = [−0.48–2.98], P = 0.16). In the thoracoscopic surgery group, the rate of postoperative deaths was significantly lower (95% CI = 1.24–2.75), but the occurrence of recurrences was more frequent (95% CI = 0.08–0.23). The hospital stay varied significantly across studies. There was a statistically significant difference (standard mean difference = −1.47, CI = [−2.24–−0.70], P < 0.001) in the overall effect between the groups. The complication rate was significantly lower with thoracoscopic surgery compared to open surgery (odds ratio = 0.26, CI = [0.10–0.66], P = 0.004) for the overall effect between the groups. The thoracoscopic procedure, however, was planned for milder and stable cases. Conclusion: Thoracoscopic repair of congenital diaphragmatic hernia in neonates is associated with a shorter length of hospital stay, fewer complications, and less postoperative mortality than traditional open repair. However, the rate of recurrence was found to be higher in those who underwent thoracoscopic surgery.

Short- and Long-Term Outcomes of Thoracoscopic and Open Repair For Esophageal Atresia and Tracheoesophageal Fistula

BackgroundThe aim was to evaluate short- and long-term outcomes for thoracoscopic repair of EA/TEF and compare with open repair. MethodsPatients who underwent EA/TEF repair during 2000–2020 were evaluated retrospectively. Patients with delayed repair were excluded. Demographic, operative, outcome data was collected. Outcomes were compared using Wilcoxon-rank sum tests for continuous, Chi-squared/Fisher's exact tests for categorical data. ResultsThere were 104 patients with primary repair, 49 (47.1%) underwent thoracoscopic repair per surgeon's choice. Type C accounted for 101 (97.1%) of the cases. Gestational age and birth weight were higher in the thoracoscopy group (p = 0.001). The rate of ≥3 VACTERL anomalies was higher in the OR group (p = 0.016). Operative time, rate of anastomotic leak, time to first oral feeding were similar (p > 0.05). Thoracoscopy group had decreased length of ventilation (p = 0.026) and length of stay (p = 0.029). The incidence of anastomotic stricture was higher in the thoracoscopy group (p = 0.012). Recurrent TEF was one case in each group. Rates of tube feeding at discharge and in first year were similar (p > 0.05), rate in third year was decreased (p = 0.032) in the thoracoscopy group. Rates of anti-reflux medication in first and third years, and fundoplication rate were similar (p > 0.05). ConclusionsMany of the short- and long-term outcomes are comparable between thoracoscopic and open repair of EA/TEF. Length of ventilation, length of stay are decreased in the thoracoscopy group. Anastomotic stricture is higher, the need for long-term tube feeding is lower after thoracoscopic repair. Although these results could be affected by selection bias, they are still promising for advancing thoracoscopic repair of EA/TEF safely and efficiently. Level of EvidenceLevel III.

Post-intubation tracheal injury during esophagectomy

Post-intubation tracheal injuries are rare complications with serious consequences. Several factors increase the risk of tracheal injuries which may be attributed to patient, or procedure related. Majority of the tracheal injuries are managed surgically, however, role of less invasive and conservative treatment are also emerging. Case: we report a case of an elderly lady who underwent minimally invasive esophagectomy for esophageal carcinoma. She developed significant surgical emphysema within hours after surgery and massive air leak through underwater seal chest drainage tube. She was taken for emergency re-exploration. On table bronchoscopy confirmed 5 cm longitudinal tear of membranous part of cervical and upper thoracic trachea. Thoracoscopic repair along with transcervical-transtracheal repair of membranous wall of trachea and a tracheostomy was performed. She made significant recovery with few complications which were managed successfully.

Comprehensive meta-analysis of surgical procedure for congenital diaphragmatic hernia: thoracoscopic versus open repair

PurposePrevious studies have shown a higher recurrence rate and longer operative times for thoracoscopic repair (TR) of congenital diaphragmatic hernia (CDH) compared to open repair (OR). An updated meta-analysis was conducted to re-evaluate the surgical outcomes of TR.MethodsA comprehensive literature search comparing TR and OR in neonates was performed in accordance with the PRISMA statement (PROSPERO: CRD42020166588).ResultsFourteen studies were selected for quantitative analysis, including a total of 709 patients (TR: 308 cases, OR: 401 cases). The recurrence rate was higher [Odds ratio: 4.03, 95% CI (2.21, 7.36), p < 0.001] and operative times (minutes) were longer [Mean Difference (MD): 43.96, 95% CI (24.70, 63.22), p < 0.001] for TR compared to OR. A significant reduction in the occurrence of postoperative bowel obstruction was observed in TR (5.0%) compared to OR (14.8%) [Odds ratio: 0.42, 95% CI (0.20, 0.89), p = 0.02].ConclusionsTR remains associated with higher recurrence rates and longer operative times. However, the reduced risk of postoperative bowel obstruction suggests potential long-term benefits. This study emphasizes the importance of meticulous patient selection for TR to mitigate detrimental effects on patients with severe disease.

Thoracoscopic primary repair of esophageal atresia and tracheoesophageal fistula: Our early experience

Background: Thoracoscopic repair of esophageal atresia (EA) and tracheoesophageal fistula (TEF) has been practiced more frequently in the past two decades. This study focuses on assessing our early experience with implementing this minimally invasive technique in neonates. Methods: Neonates with EA/TEF who were admitted to the NICU at Ain Shams University hospitals during the period from 2021 to 2022 were enrolled in the study. Thoracoscopic primary repair was performed for neonates with a body weight exceeding 2 kg. Neonates with associated major cardiac, pulmonary, and neurological anomalies and long gap atresia were excluded from the study. Results: A total of 38 neonates presented with EA/TEF during the study period. Out of these neonates, 12 cases underwent thoracoscopic primary repair. The thoracoscopic approach was used to complete all necessary repairs, and no intraoperative complications occurred. The mean operating time was 125 minutes, ranging from 105 to 150 minutes. No evidence of leakage was found in any case, as determined by both clinical and radiological contrast swallow examinations. The mean ventilation time was 7.2 days, and the mean hospital stay was 21 days. There were four deaths attributed to complications related to barotrauma and sepsis. Conclusion: Thoracoscopic repair of EA can be performed safely, which yields favorable functional and cosmetic outcomes. However, it remains a challenging procedure that requires a long learning curve.

Thoracoscopic primary repair is useful for esophageal atresia with tracheoesophageal fistula in neonates with low body weight

PurposeThe surgical indication of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula is under debate. The current study aimed to investigate the outcome of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula in patients weighing < 2000 g and those who underwent emergency surgery at the age of 0 day.MethodsThe surgical outcomes were compared between patients weighing < 2000 g and those weighing > 2000 g at surgery and between patients who underwent surgery at the age of 0 day and those who underwent surgery at age ≥ 1 day.ResultsIn total, 43 patients underwent thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula. The surgical outcomes according to body weight were similar. Patients who underwent surgery at the age of 0 day were more likely to develop anastomotic leakage than those who underwent surgery at the age of ≥ 1 day (2 vs. 0 case, p = 0.02). Anastomotic leakage was treated with conservative therapy.ConclusionThoracoscopic primary repair is safe and useful for esophageal atresia with tracheoesophageal fistula even in newborns weighing < 2000 g. However, emergency surgery at the age of 0 day should be cautiously performed due to the risk of anastomotic leakage.

Transitioning from thoracotomy to thoracoscopy for esophageal atresia in an LMIC setting

IntroductionAlthough the benefits of thoracoscopic esophageal atresia repair (TEAR) are well documented, there has been resistance to the uptake of this approach in low- and middle-income countries. This study reviews a single unit's experience introducing TEAR in a South African state sector tertiary hospital. MethodWe describe how we set up MIS for esophageal atresia (EA) at our centre. All neonates with EA managed at our institution from January 2016 to January 2022 were included. Excluded patients included those who were not operated on or if data was missing. We compared the different approaches for managing type C EA in our setting. We analyzed the data using the Mann-Whitney U test. ResultsSixty-five patients were managed with EA over the study duration. There were 54 patients who had type C EA. Thirty-nine patients underwent thoracotomy to repair the defect, and eighteen underwent TEAR, of which sixteen were completed thoracoscopically. There was a statistically significant difference in weight (p-value 0.035), gestational age (p-value 0.002), and age at operation (p-value 0.004) between the groups treated by TEAR and OEAR (open esophageal atresia repair). There was a small median difference in the operative time between TEAR and OEAR of 20 min. The mortality in the OEAR group was higher (20.5 %) compared to the TEAR group (5.5 %), with a p-value of 0.094. ConclusionA dedicated quality improvement program focused on introducing MIS for EA can produce results comparable to the open procedure in an LMIC setting.

Postoperative pulmonary vascular growth in patients with congenital diaphragmatic hernia

BackgroundPostoperative pulmonary growth in congenital diaphragmatic hernias (CDH) remains unclear. We investigated postoperative pulmonary vascular growth using serial lung perfusion scintigraphy in patients with CDH.MethodsNeonates with left CDH who underwent surgery and postoperative lung perfusion scintigraphy at our institution between 2001 and 2020 were included. Patient demographics, clinical courses, and lung scintigraphy data were retrospectively analyzed by reviewing medical records.ResultsTwenty-one patients with CDH were included. Of these, 10 underwent serial lung scintigraphy. The ipsilateral perfusion rate and median age on the 1st and serial lung scintigraphy were 32% (34 days) and 33% (3.6 years), respectively. Gestational age at prenatal diagnosis (p = 0.02), alveolar–arterial oxygen difference (A-aDO2) at birth (p = 0.007), and preoperative nitric oxide (NO) use (p = 0.014) significantly correlated with the 1st lung scintigraphy. No other variables, including operative approach, were significantly correlated with the 1st or serial scintigraphy findings.All patients improved lung perfusion with serial studies [Difference: + 7.0 (4.3–13.25) %, p = 0.001, paired t-test]. This improvement was not significantly correlated with preoperative A-aDO2 (p = 0.96), NO use (p = 0.28), or liver up (p = 0.90). The difference was significantly larger in patients who underwent thoracoscopic repair than in those who underwent open abdominal repair [+ 10.6 (5.0–17.1) % vs. + 4.25 (1.2–7.9) %, p = 0.042].ConclusionOur study indicated a postoperative improvement in ipsilateral lung vascular growth, which is possibly enhanced by a minimally invasive approach, in patients with CDH.

Endoscopic repair of tracheoesophageal fistulas: A contemporary multi-institutional case series and literature review

ObjectivesRecurrent and primary tracheoesophageal fistulas (TEFs) are a challenging surgical pathology to treat, as standard open surgical approaches are associated with high morbidity and mortality. As such, endoscopic modalities have gained interest as an alluring alternative, yet variable success rates have been reported in the literature. The aim of this study was to provide a contemporary update of the literature and describe our institutional experience with the bronchoscopic obliteration of recurrent and primary TEFs. MethodsRetrospective chart review of all pediatric patients having undergone endoscopic TEF repair at two pediatric academic centers in Montreal, Canada and Lille, France between January 1, 2008 to December 31, 2020. Results28 patients with TEFs (20 recurrent, 8 primary) underwent a total of 48 endoscopic procedures. TEF repair was performed under endoscopic guidance using various combinations of techniques, including fistula de-epithelialization (endoscopic brush, thulium laser, trichloroacetic acid-soaked pledgets or electrocautery), tissue adhesives, submucosal augmentation, esophageal clip and stenting. Successful closure was achieved in 16 patients (57 %), while 12 (43 %) required eventual open or thoracoscopic repair. The mean number of endoscopic procedures was 1.7. There were no major treatment-related complications such as pneumothorax, mediastinitis or death (mean follow-up 50.8 months). ConclusionsEndoscopic repair of recurrent or primary TEFs is a valuable component of our therapeutic armamentarium and may contribute to decreased surgical morbidity in this complex patient population. Families should be counselled that endoscopic results may be more modest than with open or thoracoscopic approaches, and multiple procedures may be required.

Thoracic Musculoskeletal Deformities Following Surgical Treatment of Esophageal Atresia - Thoracoscopic Versus Open Approach: A Retrospective Two Centers Cohort Study

IntroductionThoracic musculoskeletal deformities are significant complications following open correction of esophageal atresia (EA) during long-term follow-up. We aimed to compare the frequency and severity of thoracic musculoskeletal deformities after open and thoracoscopic repair of EA. We hypothesized that fewer deformities would occur following the less invasive thoracoscopic approach. MethodsThis retrospective study analyzed patients treated at two pediatric surgery departments in Poland between 2005 and 2021. The patient groups differed in surgical approach, operative techniques, indications for multi-staged surgery, and postoperative complications. The study encompassed all types of EA/TEF. The first group comprised 68 patients who underwent thoracoscopic esophageal atresia repair (Wroclaw), while the second group involved 44 patients who underwent open repair (Warsaw). Clinical data were retrospectively reviewed, with results considered significant at p < 0.05. ResultsThe median age at examination was 6 years in the thoracoscopy group and 5.5 years in the thoracotomy group. In the thoracoscopy group, 53 out of 68 patients (77.9%) and in the thoracotomy group – 35 out of 44 patients (79.5%) were treated in one stage. The incidence of thoracic musculoskeletal deformities was significantly lower in the thoracoscopy group (1.5%) compared to the thoracotomy group (34.1%, p < 0.001). Scoliosis occurred significantly more often after thoracotomy (13.6% vs 1.5%, p = 0.016). There was no rib fusion (0% vs 37.1%, p < 0.001) and no scoliosis of =>20° (0% vs 6.8%, p = 0.058) after thoracoscopy. The coincidence of rib fusion and scoliosis was significant (9.1%, p = 0.022) for the open approach. In the thoracotomy group, multi-staged surgery and more frequent reoperations due to major complications were significantly associated with an increased occurrence of deformities. None of the patients after thoracoscopic multi-stage or complicated EA/TEF repair developed scoliosis. ConclusionsThe frequency and severity of thoracic musculoskeletal deformities were significantly lower after the thoracoscopic approach. Thoracoscopy may be a more advantageous and preferred surgical approach for the EA/TEF treatment, although further randomized, controlled studies are necessary. Post-thoracotomy scoliosis may progress to a severity requiring surgery.

Minimally Invasive Mitral Valve Repair: From Total Endoscopic To Closed-Chest Robotic.

Minimally invasive cardiac surgery has evolved over the past few decades, thanks to advancements in technology and surgical techniques. These advancements have allowed surgeons to perform cardiac interventions through small incisions, reducing surgical trauma and improving patient outcomes1. However, despite these advancements, thoracoscopic mitral repair has not been widely adopted by the cardiac surgery community, possibly due to the lack of familiarity with video-assisted procedures1. Over the years, various minimally invasive mitral valve surgery (MIMVS) techniques have been developed to achieve comparable or better results while minimizing surgical trauma. These techniques have evolved from direct-vision procedures performed through a right thoracotomy with a rib retractor to video-directed approaches using long-shafted instruments1. Robotic surgery, introduced in the late 90s, has also played a significant role in mitral valve repair. The da Vinci system, the only robotic platform currently used for cardiac surgery, provides surgeons with enhanced dexterity and high-definition 3D visualization, allowing for precise and accurate procedure2, and is now the preferred approach for mitral repair in many programs3. The first mitral repair using the da Vinci system was performed in Europe by Carpentier and Mohr in 1998, followed by the first mitral replacement by Chitwood in the USA in 20002-4. The advantages of robotic technology allow surgeons to perform complex repair techniques such as papillary muscle repositioning and sliding leaflet plasty4. Studies have shown that robotic mitral surgery results in shorter ICU and hospital stays, better quality of life postoperatively, and improved cosmesis compared to conventional surgery5,6. In our experience, we have also observed significant benefits with robotic surgery, including reduced blood loss and the need for transfusions. This can be attributed to the closed-chest technique, which eliminates the need for a thoracotomy and rib retractor, reducing the risk of bleeding associated with these approaches7. In this article, we will compare the surgical steps of endoscopic and robotic mitral valve repair, providing detailed information on patient selection, operative techniques, and the requirements for building a successful program. By understanding the advantages and challenges of both approaches, surgeons can make informed decisions and provide the best possible care for their patients. Combined ablation and multivalvular procedures are mostly performed in few centers by minimally invasive techniques.

Thoracoscopic Stage Internal Traction Repair Reduces Time to Achieve Esophageal Continuity in Long Gap Esophageal Atresia.

Management of long gap esophageal atresia (LGOA) is controversial. This study aims at comparing the management of LGOA between two high-volume centers. We included patients with LGOA (type A and B) between 2008 and 2022. Demographics, surgical methods, and outcomes were collected and compared. The study population involved 28 patients in center A and 24 patients in center B. A surgical approach was thoracoscopic in center A, only for one patient was open for final procedure. In center B, 3 patients were treated only thoracoscopically, 2 converted to open, and 19 as open surgery. In center A primary esophageal anastomosis concerned 1 case, two-staged esophageal lengthening using external traction 1 patient, and 26 were treated with the multistaged internal traction technique. In 24 patients a full anastomosis was achieved: in 23 patients only the internal traction technique was used, while 1 patient required open Collis-Nissen procedure as final management. In center B primary anastomosis was performed in 7 patients, delayed esophageal anastomosis in 8 patients, esophageal lengthening using external traction in 1 case, and 9 infants required esophageal replacement with gastric tube. Analyzed postoperative complications included: early mortality, 2/28 due to accompanied malformations (center A) and 0/24 (center B); anastomotic leakage, 4/26 (center A) treated conservatively-all patients had a contrast study-and 0/24 (center B), 1 case of pleural effusion, but no routine contrast study; recurrent strictures, 13/26 (center A) and 7/15 (center B); and need for fundoplication, 5/26 (center A) and 2/15 (center B). Age at esophageal continuity was as a median of 31 days in center A and 110 days in center B. Median time between initial procedure and esophageal anastomosis was 11 days in center A and 92 days in center B. Thoracoscopic internal traction technique reduces time to achieve esophageal continuity and the need for esophageal substitution while maintaining a similar early complication rate.

Use of Barbed Sutures for Congenital Diaphragmatic Hernia Repair.

Congenital diaphragmatic hernia (CDH) repair can be challenging, particularly when a larger defect is present. Barbed sutures prevent the suture from slipping back after approximation of the tissues. Although introduced almost 2 decades ago, barbed sutures have not been widely used for CDH repair. We report our initial experience and pitfalls. All patients presenting with CDH from 2021 onward underwent repair using barbed sutures. Demographics, operative parameters, complications, and outcomes were prospectively recorded. A total of 13 patients underwent CDH repair during the study interval (median age 6 days, range 3 days to 5.75 years). Median operative time was 89 min (range 46 to 288 min). Five thoracoscopic and eight open procedures were performed. Severe pulmonary hypertension and ECMO (extracorporeal membrane oxygenation) were considered contraindications for thoracoscopic repair. The included patients were compared to a historic controlled group performed without barbed sutures. The barbed suture facilitated easy and quick closure of the defects in most cases and obviated the need for knot tying. One patient in the thoracoscopic group had a patch placed due to high tension after the barbed sutures tore the diaphragm. At a median follow-up time of 15 months (range 2 to 34 months), one patient had died, and one patient with complete diaphragmatic agenesis was home-ventilated. There were no recurrences. Median operative time trended lower (89 min) than in the historic control group repaired without barbed sutures (119 min, p < 0.06) after eliminating outliers with large, complex patch repairs. Barbed sutures simplify congenital diaphragmatic hernia repair regardless of whether a minimal-invasive or open approach is performed. Patch repair is not a contraindication for using barbed sutures. The resulting potential time savings make them particularly useful in patients with cardiac or other severe co-morbidities in which shorter operative times are essential. In cases with high tension, though, the barbs may tear through and produce a "saw" effect on the tissue with subsequent damage.

Open Versus Thoracoscopic Repair of Congenital Diaphragmatic Hernia: A 19-Year Review in a Tertiary Referral Centre in Hong Kong

BackgroundCongenital 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. MethodsWe 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. Results64 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. ConclusionsThis 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.
