RESUMO
BACKGROUND: The identification of the intersegmental plane (ISP) is a crucial step in segmentectomy for children with congenital pulmonary airway malformation (CPAM) due to complex anatomical variations. However, there is very limited literature available on this aspect specifically for infant. In this study, we compared the intravenous indocyanine green (ICG)-guided near-infrared fluorescence (NIRF) imaging method with the modified inflation-deflation method in terms of their perioperative characteristics and summarized our experience. METHODS: From June 2021 to November 2022, the data of 83 patients with CPAM who underwent segmentectomy by video-assisted thoracoscopic surgery were retrospectively reviewed. Twenty-eight patients underwent ICG-guided NIRF method, and 56 patients underwent the modified inflation-deflation method, characteristics and clinical outcomes were compared. RESULTS: The median age of the patients was 4.99 months (4.99 ± 1.51) with a mean body weight of 7.54 kg (7.54 ± 1.99). Both methods could accurately identify the ISP. The time taken to clearly display the ISP was shorter in ICG group than in the modified inflation-deflation group (0.18 ± 0.08 vs. 6.49 ± 1.67 min; P < 0.001), and the surgical duration (61.32 ± 14.28 vs. 88.18 ± 8.03 min; P < 0.001) were significantly shorter in the ICG group too. The two groups exhibited differences in the length of chest tube drainage (1.75 ± 1.24 vs. 2.36 ± 1.54 days; P = 0.072) and the length of hospital stay (4.61 ± 1.75 vs. 5.20 ± 3.07 days; P = 0.078), however, the differences were not statistically significant. There were no significant differences between the two groups in the blood lost and postoperative complications. At a follow-up of more than 1 year after operation, all patients had recovered well without recurrence. CONCLUSIONS: According to our experience, the ICG-guided NIRF method was safe and feasible for infants during thoracoscopic segmentectomy, it can quickly display the ISP and shorten the surgical duration compared with the modified inflation-deflation method.

BACKGROUND: Video-assisted thoracoscopic surgery is a commonly used procedure for treating congenital pulmonary airway malformation (CPAM) in infants, particularly when performing segmentectomy for segmental lesions. An innovative technique employing near-infrared fluorescence (NIRF) imaging with intravenous indocyanine green (ICG) has been utilized to delineate the intersegmental demarcation during surgery. However, no previous reports have investigated this method's application, specifically in infants. The primary aim of this study was to assess the safety and efficacy of the NIRF imaging with ICG approach in this context. METHODS: Between January 2021 and April 2022, a total of 19 consecutive segmentectomies were conducted using the NIRF imaging with ICG method to precisely identify the intersegmental plane. The results were concurrently compared with those obtained using the modified inflation-deflation technique. Comprehensive imaging and clinical data were gathered and analyzed to assess the safety and accuracy of the NIRF imaging with ICG approach. RESULTS: The study involved infants with a median age of 5.12 months (mean body weight of 8.08 g). All segmentectomies were performed successfully without any ICG-related complications. The mean operating time for the surgeries was 88.47 ± 7.94 minutes. Notably, no intraoperative conversions or significant complications were observed in any of the patients. The average hospital stay after surgery was 4.0 ± 0.82 days. During the follow-up period, extending beyond 1-year of postoperation, all patients exhibited excellent recovery with no cases of recurrence. CONCLUSIONS: Based on our experience, the NIRF imaging with intravenous ICG method proved to be both safe and effective when performing segmentectomy for infants with CPAM. Low doses of ICG did not hinder the accurate identification of the intersegmental plane.
RESUMO
PURPOSE: Tension pneumomediastinum is a rare and dangerous complication in children that can be fatal, and timely detection and treatment are critical. The aim of this study was to evaluate the safety and feasibility of computed tomography (CT) imaging-guided parasternal approach drainage for tension pneumomediastinum in children. METHODS: From June 2018 to February 2023, we consecutively enrolled 19 children with tension pneumomediastinum in our institution. A pigtail catheter was inserted into the anterior mediastinum by a CT imaging-guided parasternal approach. The catheter was connected to a negative-pressure water seal bottle to drain the pneumomediastinum. Clinical data and outcomes were summarized. RESULTS: The mean age was 3.1 ± 3.4 years, the mean weight was 15 ± 9.1 kg, the mean procedure time was 11.8 ± 2.4 min, and the drainage time was 6.7 ± 3.4 days. No major complications were identified, such as haemothorax, catheter displacement, or mediastinal infection. Effective drainage was obtained in all patients as assessed by comparing images and ventilatory parameters, and no additional surgical treatment was needed. There was no recurrence during the follow-up, which was more than 2 months. In our data, two children with COVID-19 were discharged from the hospital after effective drainage and other clinical treatment. CONCLUSION: CT-guided parasternal approach drainage is safe, minimally invasive, and effective for children with tension pneumomediastinum.

Introduction: Congenital diaphragmatic hernia (CDH) is a structural defect caused by inadequate fusion of the pleuroperitoneal membrane that forms the diaphragm, allowing peritoneal viscera to protrude into the pleural cavity. Up to 30% of newborns with CDH require extracorporeal membrane oxygenation (ECMO) support. As with all interventions, the risks and benefits of ECMO must be carefully considered in these patients. Cardiopulmonary function has been shown to worsen rather than improve after surgical CDH repair. Even after a detailed perioperative assessment, sudden cardiopulmonary failure after surgery is dangerous and requires timely and effective treatments. Method: Three cases of cardiopulmonary failure after surgical CDH treatment in newborns have been reported. ECMO support was needed for these three patients and was successfully discontinued. We report our treatment experience. Conclusion: ECMO is feasible for the treatment of postoperative cardiopulmonary failure in newborns with CDH.
RESUMO
BACKGROUND: Congenital diaphragmatic hernia (CDH) is a serious congenital malformation. Given the focus on improving survival in patients with "high-risk" CDH, it is possible that risk factors for low-risk patient with CDH may not be a concern. Left heart failure leads to adverse postoperative outcomes, including the need for extracorporeal membrane oxygenation (ECMO). The purpose of this study was to explore the causes of postoperative left heart failure in the low-risk group. METHODS: A retrospective study was conducted on newborns with congenital diaphragmatic hernia who were surgically treated in our hospital from January 2018 to March 2022. Children at low risk were divided into three groups according to the intraoperative repair conditions. Group A was defined as grade A defects repaired by direct suture. Group B was defined as a grade B defect repaired by mesh. Group C was a grade B defect repaired by high-tension suture. The age, gender, weight, perioperative echocardiography, and follow-up of the patients were statistically analyzed. The risk factors of left ventricular dysfunction after surgery in neonates with low-risk congenital diaphragmatic hernia were analyzed. RESULTS: A total of 52 low-risk children were included in the study. For children in the low-risk group, there was no significant difference between the low-tension repair group and the high-tension repair group in terms of operation time, thoracic tube drainage time, hospital stay, and long-term survival rate. Group A and group B showed good left ventricular function, while group C showed more decreased left ventricular EF and LVFS (LVEF 54.06 ± 10.28, LVFS 26.94 ± 5.83, p < 0.001). On the comparison of measures of left ventricular size, the mean values of left ventricular end-diastolic diameters(LVDD) and left ventricular end-systolic diameters (LVDS) were significantly difference in group C. Univariate analysis showed that LHR, o/e LHR, operation time, and high-tension repair were the influencing factors of left ventricular dysfunction. Multivariate logistic regression analysis identified risk factors for high-tension repair. Severe left heart dysfunction occurred in 2 patients with ECMO requirement in the high-tension repair group, although the difference was not significant. CONCLUSIONS: High-tension repair is a potential cause of left ventricular dysfunction in neonates with low-risk CDH.

PURPOSE: To evaluate the safety and efficacy of single-direction lobectomy for congenital pulmonary airway malformation (CPAM), especially with incomplete pulmonary fissure (IPF). METHODS: A total of 279 patients who underwent thoracoscopic lobectomy in our hospital from January 2019 to January 2022 were analyzed. Fifty-nine children were identified as the single-direction group, and the details of the surgical application are described. The degree of pulmonary fissure completeness was quantified intraoperatively. Propensity score matching was conducted and another 59 patients who underwent conventional lobectomy were matched as the control group. RESULTS: The median age of the patients was 4.9 months and the mean body weight was 7.7 kg. For patients with complete pulmonary fissure, there were no statistical differences between two groups in terms of operative time, intraoperative blood loss, length of chest tube, and hospital stay. For patients with IPF, there were statistical differences between the single-direction group and the control group in terms of operative times (89.10 ± 7.97 min vs. 97.41 ± 7.51 min, P < 0.001), intraoperative blood loss (10.86 ± 5.36 mL vs. 14.14 ± 6.56 mL P = 0.042), and postoperative complications (P = 0.035). CONCLUSION: IPF increases the operative difficulty of thoracoscopic lobectomy for CPAM, and the single-direction lobectomy technique is an effective and safe treatment for IPF.

BACKGROUND: Thoracoscopic lobectomy is a common treatment for congenital lung malformation. Single-direction thoracoscopic lobectomy may be an effective and safe approach without the need to flip the lung over repeatedly, thus minimizing tissue trauma, but its use has not been reported in children. The purpose of this study was to evaluate the safety and efficacy of single-direction thoracoscopic lobectomy in children. METHODS: A total of 91 patients who underwent thoracoscopic lobectomy in our hospital from January 2020 to December 2020 were retrospectively analysed. According to the inclusion criteria, 21 children were identified as the single-direction group. The details of the single-direction thoracoscopic lobectomy technique are described. Another 21 patients who underwent conventional thoracoscopic lobectomy in the same period were matched using the propensity score matching and set as the control group, the clinical outcomes between the two groups were compared. RESULTS: The median age of the patients was 4.72 months (4.72 ± 0.90) with a mean body weight of 7.43 kg (7.43 ± 1.14). There were no significant differences in intraoperative blood loss (P = 0.549), operation time (P = 0.859), length of chest tube drainage (P = 0.102) and length of hospital stay (P = 0.636) between the 2 groups. No patients experienced bronchopleural fistula and conversion to thoracotomy in either group. All patients recovered well without respiratory symptoms or other complications after follow-up of more than 1 year. CONCLUSIONS: Our preliminary experience presented a series of single-direction video-assisted thoracoscopic lobectomy for children with satisfactory perioperative results.

We performed a single-centre retrospective analysis using data from databases that were prospectively maintained in our centre between January 2019 and September 2021. Patients were divided into two groups based on the degree of pulmonary fissure completeness (PFC), using the fissure development scoring system. Patients with grades 2 or 3 PFC were considered to have incomplete pulmonary fissures and were included in Group A, and patients with grades 0 and 1 were considered to have complete pulmonary fissures and were included in Group B. The differences in demographics, perioperative characteristics and clinic outcomes between the two groups were evaluated. Multivariate logistic regression analysis was performed. A total of 213 patients with congenital lung malformation (CLM) underwent video-assisted thoracoscopic lobectomy. There were 30 patients in Group A and 183 patients in Group B. Our data showed that compared with Group B, Group A had a higher incidence of complications, especially Clavien-Dindo grade II and grade III complications. The degree of PFC was significantly correlated with the length of chest tube drainage and postoperative hospital stay. Multivariate logistic regression analysis showed that the degree of PFC could be used to predict the incidence of postoperative complications.ConclusionsThe degree of PFC is a predictor of the incidence of complications after thoracoscopic lobectomy in children with CLM.

BACKGROUND: The aim of this study was to determine a predictive index for the risk of anastomotic leak following esophageal atresia anastomosis, METHODS: This article reviewed the clinical data of 74 children with esophageal atresia in Fujian Children's hospital. The risk factors for anastomotic leak were analysed, and a new predictive index was proposed. RESULTS: The incidence of anastomotic leak was 29.7% after anastomosis in 74 children with esophageal atresia. Birth weight and gap length were risk factors for anastomotic leak. Logistic regression analysis showed that birth weight (Wald 2 = 4.528, P = 0.033, OR = 0.273) was a protective factor for anastomotic leak, whereas gap length (Wald 2 = 7.057, P = 0.008, OR = 2.388) was a risk factor for anastomotic leak. The ratio of gap length to birth weight had a positive predictive effect on the occurrence of anastomotic leak (AUC = 0.732, P = 0.002). CONCLUSION: Birth weight and gap length are important predictors of anastomotic leak in esophageal atresia. Measurement of the ratio of gap length to birth weight is a helpful predictive index for anastomotic leak following the anastomosis of esophageal atresia.

Purpose: The effectiveness of video-assisted thoracic surgery (VATS), even uniportal VATS (U-VATS), in the treatment of pleural empyema has recently been demonstrated. However, few works have evaluated its safety and feasibility for children. We review our experience with U-VATS in the treatment of pleural empyema for children under 11 years old. Methods: From January 2019 to December 2020, we consecutively enrolled 21 children with stage II and stage III pleural empyema in our institution. A 1.0 cm utility port was created in the 5th intercostal space at the anterior axillary line. A rigid 30°5 mm optic thoracoscope was used for vision, and two or three instruments were used through the port. Surgery was based on three therapeutic columns: removal of pleural fluid, debridement, and decortication. A chest tube was inserted through the same skin incision. Perioperative data and outcomes were summarized. Results: The procedures were successful, and satisfactory debridement of the pleural cavity was achieved in all cases. The mean age was 4.1 years (range: 6 months to 11 years old). The mean operating time was 65.7 ± 23.2 min. No intraoperative conversion or major complications were identified among the patients. The mean hospital stay was 5.0 ± 0.6 days. At a follow-up of more than 4 months after operating, all patients had recovered well without recurrence. Conclusion: According to our experience, U-VATS debridement is feasible for the surgical management of stage II and III empyema in the pediatric population. Indeed, U-VATS permits easier performance and complete debridement and decortication, with a very low risk for conversion.
RESUMO
Purpose: This study aimed to compare the outcomes and pulmonary function test (PFT) of thoracoscopic segmentectomy and lobectomy in infants with congenital lung malformation and study the result of PFT on a medium-term basis. Methods: The clinical data of 19 infants with congenital lung malformation who underwent thoracoscopic surgery in our hospital from January 2018 to March 2019 were retrospectively studied; these infants were paired with another 19 infants who underwent thoracoscopic lobectomy during the same period using propensity score matching. Age-matched healthy individuals with similar body sizes were recruited for PFT as the control group. Patient characteristics, postoperative PFT, and outcomes were extracted for statistical analysis. Results: The average length of hospital stay did not significantly differ between segmentectomy and lobectomy groups. The segmentectomy group had more chest tube drainage than the lobectomy group. PFT 1 month after the operation showed that the tidal volume of the lobectomy group was lower than that of the segmentectomy group. Time to peak expiratory flow/time of expiration and peak flow/terminal airway velocity (V25%) indicated small airway dysfunction in the lobectomy group, and no obvious abnormalities were found in "time of inspiratory/time of expiration" in either group. Reexamination of pulmonary function 2 years after the operation showed that the small airway function of the segmentectomy group returned to normal, and no significant difference in pulmonary function was noted among the three groups. Conclusion: The short-term pulmonary function recovery was better after segmentectomy than after lobectomy. Patients who underwent thoracoscopic lobectomy and segmentectomy have normal lung function 2 years after the operation.
RESUMO
BACKGROUND: In infants with congenital oesophageal atresia, anastomotic stenosis easily occurs after one-stage oesophageal anastomosis, leading to dysphagia. In severe cases, oesophageal dilatation is required. In this paper, the timing of oesophageal dilatation in infants with anastomotic stenosis was investigated through retrospective data analysis. METHODS: The clinical data of 107 infants with oesophageal atresia who underwent one-stage anastomosis in our hospital from January 2015 to December 2018 were retrospectively analysed. Data such as the timing and frequency of oesophageal dilatation under gastroscopy after surgery were collected to analyse the timing of oesophageal dilatation in infants with different risk factors. RESULTS: For infants with refractory stenosis, the average number of dilatations in the early dilatation group (the first dilatation was performed within 6 months after the surgery) was 5.75 ± 0.5, which was higher than the average of 7.40 ± 1.35 times in the normal dilatation group (the first dilatation was performed 6 months after the surgery), P = 0.038. For the infants with anastomotic fistula and anastomotic stenosis, the number of oesophageal dilatations in the early dilatation group was 2.58 ± 2.02 times, which was less than the 6.38 ± 2.06 times in the normal dilatation group, P = 0.001. For infants with non-anastomotic fistula stenosis, early oesophageal dilatation could not reduce the total number of oesophageal dilatations. CONCLUSION: Starting to perform oesophageal dilatation within 6 months after one-stage anastomosis for congenital oesophageal atresia can reduce the required number of dilatations in infants with postoperative anastomotic fistula and refractory anastomotic stenosis.

BACKGROUND: Oesophageal atresia is a congenital malformation of the oesophagus and a serious malformation of the digestive system, postoperative complications include acute respiratory failure, pneumonia, anastomotic fistula, anastomotic stenosis, tracheal stenosis, gastroesophageal reflux and eosinophilic oesophagitis, anastomotic fistula is one of the important causes of postoperative death. The objective of this study is to identify the risk factors for anastomotic complications after one-stage anastomosis for oesophageal atresia. METHODS: A retrospective analysis was performed on the clinical data of 107 children with congenital oesophageal atresia who underwent one-stage anastomosis in our hospital from January 2013 to December 2018. Single-factor and multivariate logistic regression analyses were performed to determine the risk factors for anastomotic fistula and anastomotic stenosis. RESULTS: A total of 107 children with oesophageal atresia underwent one-stage anastomosis, and the incidence of anastomotic fistula was 26.2%. The probability of anastomotic stenosis in the long term was 52.3%, and the incidence of refractory stenosis (dilation ≥5 times) was 13.1%. Analysis of the clinical count data in the anastomotic fistula group and non-anastomotic fistula group showed that preoperative albumin (F = 4.199, P = 0.043), low birth weight (F = 7.668, P = 0.007) and long gap defects (F = 6.107, P = 0.015) were risk factors for postoperative anastomotic fistula. Further multivariate logistic regression analysis showed that low birth weight (Wald2 = 4.499, P = 0.034, OR = 2.775) and long gap defects (Wald2 = 6.769, P = 0.009, OR = 4.939) were independent risk factors for postoperative anastomotic fistula. Premature delivery (F = 5.338, P = 0.023), anastomotic fistula (F = 11.381, P = 0.001), endoscopic surgery (F = 6.343, P = 0.013), preoperative neutrophil count (F = 8.602, P = 0.004), preoperative low albumin (F = 8.410, P = 0.005), and a preoperative prognostic nutritional index < 54 (F = 5.54, P = 0.02) were risk factors for refractory anastomotic stenosis in children. Further multivariate logistic regression analysis showed that postoperative anastomotic fistula (Wald2 = 11.417, P = 0.001, OR = 8.798), endoscopic surgery (Wald2 = 9.633, P = 0.002, OR = 4.808), and a prognostic nutritional index < 54 (Wald2 = 4.540, P = 0.002, OR = 2.3798) were independent risk factors for refractory anastomotic stenosis. CONCLUSION: Low birth weight and long gap defects are important predictors of postoperative anastomotic fistula, and the possibility of refractory anastomotic stenosis should be considered. The long-term risk of anastomotic stenosis was increased in children undergoing endoscopic surgery and in those with a preoperative prognostic nutritional index < 54.

Background: The present study aimed to evaluate the safety and feasibility of uniportal video-assisted thoracoscopic surgery (U-VATS) for infants with pulmonary sequestration (PS). Methods: From January 2019 to July 2020, 19 infants with PS were admitted to a provincial hospital in the Fujian Province of China. A 1.5-cm utility port was created in the fifth intercostal space at the anterior axillary line. A rigid 30° 5-mm optic thoracoscope was used for vision, and two or three instruments were utilized through the port. Surgical options include standard lobectomy, wedge resection, and resection of the extralobar sequestration. Only one intercostal space was entered, and a chest tube was inserted through the same skin incision if necessary. Results: The procedure was successful in all patients with an average operation duration of 58.3 ± 31.5 min. The length of post-operative hospital stay was 5.4 ± 1.5 days, and no post-operative deaths or serious complications were observed. The mean post-operative drainage volume was 164.6 ± 45.9 mL, and the mean post-operative thoracic tube indwelling duration was 5.5 ± 1.0 days. No intraoperative conversion, surgical mortality, or major complications were identified among the patients. Conclusion: Our preliminary experience presented a series of U-VATS lobectomy, wedge resection, and resection of the PS for infants with satisfactory perioperative results.
