RESUMO
PURPOSE: Congenital esophageal stenosis (CES) associated with esophageal atresia (EA) is rare, and no standard treatment has been established. We reviewed cases of EA-associated CES to assess the clinical characteristics and treatment outcomes, especially the feasibility of endoscopic dilatation. METHODS: We retrospectively examined patients with EA-associated CES. We also compared treatment outcomes of EA-associated CES with those of EA patients without CES who developed postoperative anastomotic stricture. RESULTS: Among 44 patients with EA, ten had CES (23%). Postoperative complications were not significantly different between EA patients with CES and those without CES but with anastomotic stricture. All CES patients underwent balloon dilatation as initial treatment. Eight of nine patients (89%) were successfully treated by dilatation only, and one patient underwent surgical resection. The median number of balloon dilatations for CES was five (2-17), which was higher than that for anastomotic stricture in patients without CES (p = 0.012). Esophageal perforation occurred in five patients with CES (5/9, 56%) after dilatation, but all perforations were successfully managed conservatively with an uneventful post-dilatation course. CONCLUSIONS: Twenty-three percent of patients with EA had CES. Although balloon dilatation for EA-associated CES required multiple treatments and carried a risk of perforation, balloon dilatation showed an 89% success rate and all perforations could be managed conservatively.

PURPOSE: Thoracoscopic repair (TR) of congenital diaphragmatic hernia (CDH) is associated with a higher recurrence rate than the conventional open method. We evaluated the effectiveness of our strategy for quality improvement, named "tension-free TR of CDH". METHODS: The subjects of this retrospective analysis were 11 consecutive patients with CDH who underwent TR at our hospital between 2017 and 2021. Tension-free TR of CDH included the proactive use of an oversized patch for dome-shaped reconstruction and gapless suturing. We developed a percutaneous extracorporeal closure technique for secure suturing using a commercially available needle. RESULTS: Patch repair was performed in 8 (73%) patients and none required conversion to open surgery because of technical difficulties. Recurrence developed in one patient (9%), who underwent successful reoperation via TR. All patients had an uneventful postoperative course. CONCLUSION: Tension-free TR combined with extracorporeal closure could reduce the difficulty of suturing and the risk of recurrence of CDH.

PURPOSES: Congenital biliary dilatation (CBD), defined as pancreaticobiliary maljunction (PBM) with biliary dilatation, is a high risk factor for biliary tract cancer (BTC). KRAS and p53 mutations reportedly affect this process, but the mechanisms are unclear, as is the likelihood of BTC later in life in children with CBD. We investigated potential carcinogenetic pathways in children with CBD compared with adults. METHODS: The subjects of this study were nine children with CBD and 13 adults with PBM (10 dilated, 3 non-dilated) without BTC who underwent extrahepatic bile duct resections, as well as four control patients who underwent pancreaticoduodenectomy for non-biliary cancer. We evaluated expressions of Ki-67, KRAS, p53, histone deacetylase (HDAC) and activation-induced cytidine deaminase (AID) in the biliary tract epithelium immunohistochemically. RESULTS: The Ki-67 labeling index (LI) and expressions of KRAS, p53, HDAC, and AID in the gallbladder epithelium were significantly higher or tended to be higher in both the children with CBD and the adults with PBM than in the controls. CONCLUSIONS: BTC may develop later in children with CBD and in adults with PBM, via HDAC and AID expression and through epigenetic and genetic regulation.

PURPOSE: The postoperative course after surgery for congenital biliary dilatation (CBD) has some complications. Intrahepatic bile duct (IHBD) stones were known as a late complication. We report on the treatment and long-term follow-up of postoperative IHBD stones in our department. METHODS: Patients who underwent CBD surgery at age 15 years or younger in our department were identified. Those followed up for 5 years or more were enrolled. Annual blood chemistry tests and abdominal ultrasonography were performed. Each patient's surgical procedure, IHBD stone diagnosis, treatments, and outcomes were retrospectively assessed. RESULTS: Fifty-one patients were analyzed. The median age at the last visit was 24 years (range 7-45 years), and the median age at CBD surgery was 3 years. Eight patients (16%) developed late-onset IHBD stones. The median age at onset was 25 years, and the median duration after surgery was 20 years. The initial treatment was double-balloon enteroscopy (DBE) in 4 cases, which resulted in stone removal in 3 of the 4 patients (75%). CONCLUSION: Since CBD may cause late-onset IHBD stones, continuous follow-up is required even in adulthood. In this study, DBE was effective and minimally invasive, and it is recommended as the initial treatment.

BACKGROUND: MicroRNAs (miRNAs) play an important role in regulating fibrogenesis in the liver. The current study examined the ability of microRNA-214 (miR-214) level in liver and serum samples obtained from patients with BA to predict progressive liver fibrosis in patients with biliary atresia (BA). METHODS: We examined miR-214 level in relation to conventional markers of liver fibrosis, with liver and serum samples from BA patients. Fifty-two patients with BA who underwent Kasai portoenterostomy and four control patients underwent liver biopsy. In 28 patients with BA, blood samples were collected to analyze circulating serum miR-214. RESULTS: MiR-214 levels in liver tissue were significantly upregulated in patients with BA who had severe liver fibrosis (F3-4) compared to those with none to mild fibrosis (F0-2), whereas suppressors-of-fused homolog (Sufu) mRNA levels were significantly suppressed in F3-4. Serum miR-214 levels were significantly higher in patients with F3-4 compared with F0-2. Area under the curve analysis showed that the serum miR-214 cut-off level for predicting F3-4 was 0.805 (p = 0.0046). CONCLUSION: Hepatic overexpression of miR-214 is associated with progression of liver fibrosis in patients with BA, and the circulating miR-214 level may serve as a non-invasive predictor of liver fibrosis.

PURPOSE: Mac-2 binding protein glycosylation-modified isomer (M2BPGi) is a new marker for hepatic fibrosis progression. We examined the relationship between serum M2BPGi levels and liver histological findings in intestinal failure (IF) patients without IF-associated liver disease (IFALD). METHODS: This study included IF patients without IFALD followed at our hospital. All patients underwent routine liver biopsies per protocol every 1-2 years. We examined M2BPGi levels and histological findings in relation to aspartate aminotransferase (AST) to platelet ratio index, fibrosis-4 index, and AST/ALT ratio. Liver fibrosis was evaluated based on the METAVIR score. RESULTS: Total 18 liver biopsies out of eight patients were included. The median age was 11.5 years. Mean M2BPGi was 0.44 cutoff index (COI) in patients with F0 fibrosis, 0.78 COI in patients with F1 fibrosis and 1.63 COI in patients with F2 fibrosis. Mean M2BPGi was significantly higher in patients with F2 versus F1 or F0 fibrosis (P < 0.016 and P < 0.028, respectively). M2BPGi levels were more strongly correlated with fibrosis stage than with other conventional fibrosis markers. CONCLUSION: Serum M2BPGi is a novel marker of liver fibrosis in patients with IF. It is useful for follow-up prior to IFALD. Serum M2BPGi levels can support the interpretation of liver status.

PURPOSE: This study aimed to evaluate prenatal predictors of mortality in fetuses with congenital diaphragmatic hernia (CDH). METHODS: A systematic literature search was performed to identify relevant observational studies that evaluated the ability of lung-to-head ratio (LHR), observed-to-expected LHR (o/e-LHR), observed-to-expected total fetal lung volume (o/e-TFLV), lung-to-thorax transverse area ratio (L/T ratio), intrathoracic herniation of the liver and the stomach, and side of diaphragmatic hernia, using a threshold for the prediction of mortality in fetuses with CDH. Study quality was assessed using the QUADAS-2 tool. Hierarchical summary receiver operating characteristic curves were constructed. RESULTS: A total of 50 articles were included in this meta-analysis. The QUADAS-2 tool identified a high risk of bias in more than one domain scored in all parameters. Among those parameters, the diagnostic odds ratio of mortality with o/e-LHR < 25%, o/e-TFLV < 25%, and L/T ratio < 0.08 were 11.98 [95% confidence interval (CI) 4.65-30.89], 11.14 (95% CI 5.19-23.89), and 10.28 (95% CI 3.38-31.31), respectively. The predictive values for mortality were similar between the presence of liver herniation and retrocardiac fetal stomach position. CONCLUSIONS: This systematic review suggests that o/e-LHR, o/e-TFLV, and L/T ratio are equally good predictors of neonatal mortality in fetuses with isolated CDH.

This is the first report of an immature sacrococcygeal teratoma with inguinal lymph node metastasis, providing the histologic transformation of an immature teratoma in association with chemotherapy. Incomplete tumor resection with coccygectomy was performed, and the histopathologic diagnosis was a grade 3 immature teratoma. Following the initial surgery, the residual tumors enlarged and the tumors metastasized to the inguinal lymph node, demonstrating immature teratoma without yolk sac tumor components. Although the tumor markers normalized after chemotherapy, the residual tumors had enlarged significantly. Therefore, a complete resection of the residual tumors was performed, and they were found to be mature teratomas.

PURPOSE: The etiology of cholestasis in neonates is associated with several factors including gastrointestinal disease and surgery. We aimed to identify the potential risk factors for perioperative cholestasis in patients with duodenal atresia and determine specific cutoff values for the risk factors. METHODS: This retrospective cohort study included 76 neonates diagnosed with duodenal atresia surgically treated during the neonatal period at our institution between January 1990 and March 2017. The neonates were categorized into two groups: those with and without cholestasis. Univariate and multivariate analyses were performed to identify the possible risk factors for cholestasis. RESULTS: Among the 76 neonates with duodenal atresia, 21 (27%) developed cholestasis. The duration of total parenteral nutrition was identified as a risk factor in univariate analysis; however, it was not an independent risk factor for cholestasis. Gestational age and highest C-reactive protein (CRP) values were independent risk factors, with adjusted odds ratios of 0.53 and 1.25, respectively. To predict the occurrence of cholestasis, the cutoff value for gestational age was 35.0 weeks, and highest CRP value was 2.4 mg/dL. CONCLUSIONS: The occurrence of cholestasis in patients with duodenal atresia was associated with preterm delivery and severity of the inflammatory response during the perioperative period.

PURPOSE: This study aimed to evaluate the incidence and factors associated with long-term functional outcomes of sacrococcygeal teratoma (SCT) after resection in neonates and infants. METHODS: Twenty-nine patients with a minimum of 3 years of follow-up who underwent resection and were histologically diagnosed with SCTs between 1982 and 2017 at our institution were included. RESULTS: The median age at the time of the study was 10.0 years. Functional disorders occurred after surgery in 6 (20.7%) patients. Anorectal dysfunction, urologic dysfunction, and lower-extremity motor disorders occurred in 6 (20.7%), 4 (13.8%), and 3 (10.3%) patients, respectively. One patient with all three types of functional disorders developed intestinal perforation due to ileus and died of sepsis at 13 years of age. The overall mortality rate after tumor resection was 3.4%. The patients who developed functional disorders presented a low 1-min Apgar score, larger tumors requiring abdominosacral resection, surgical injury to the pelvic organs, and immature or malignant histological findings. CONCLUSION: Although the mortality rate was low, the long-term rate of functional disorders after SCT resection was approximately 20%. SCT patients with large tumors, surgical injury to the pelvic organs, and immature or malignant histological findings require thorough follow-up.

PURPOSE: This study aimed to elucidate the clinical characteristics of neonates with congenital diaphragmatic hernia (CDH) associated with pneumothorax and evaluate the risk factors for the development of pneumothorax. METHODS: A retrospective cohort study was conducted in the 15 institutions participating in the Japanese CDH Study Group. A total of 495 neonates with isolated CDH who were born between 2011 and 2018 were analyzed in this study. RESULTS: Among the 495 neonates with isolated CDH, 52 (10.5%) developed pneumothorax. Eighteen (34.6%) patients developed pneumothorax before surgery, while 34 (65.4%) developed pneumothorax after surgery. The log-rank test showed that the cumulative survival rate was significantly lower in patients with pneumothorax than in those without pneumothorax. Univariate analysis revealed significant differences between patients with pneumothorax and those without pneumothorax with regard to the best oxygenation index within 24 h after birth, mean airway pressure (MAP) higher than 16 cmH2O, diaphragmatic defect size, and need for patch closure. Multiple logistic regression analysis indicated that only the MAP was associated with an increased risk of pneumothorax. CONCLUSIONS: The cumulative survival rate was significantly lower in isolated CDH patients with pneumothorax than in those without pneumothorax. A higher MAP was a risk factor for pneumothorax in CDH patients.

PURPOSE: The aim of this study was to evaluate the indications and the clinical outcomes of the fetuses managed with ex utero intrapartum treatment (EXIT) procedures. METHODS: We retrospectively reviewed the medical records of all fetuses who underwent EXIT procedures between 2003 and 2018. RESULTS: EXIT procedures were performed in nine cases. The prenatal diagnosis of the neonates was congenital high airway obstruction syndrome in four cases, the neck masse in five cases. Although the airway management under the EXIT procedure was successful in eight cases, the airway management failed in one case. During the EXIT procedures, the airway was managed by endotracheal intubation in two cases, whereas six cases underwent tracheostomy. Six cases with fetal airway obstruction survived to discharge, whereas three cases died due to airway management failure or complications of the underlying disease. A case with a cervical teratoma underwent tumor resection the day after birth due to rapid enlargement of the neck mass. Long-term survival was achieved in five cases. CONCLUSIONS: We concluded that the EXIT procedure was effective and could be performed safely in the airway management of fetuses with suspected airway obstruction. The treatment strategy for the neck masses should be planned before birth.

BACKGROUND: We aimed to investigate the clinical characteristics and outcomes of patients with isolated left-sided congenital diaphragmatic hernia (CDH) who developed preoperative pneumothorax and determine its risk factors. METHODS: We performed an international cohort study of patients with CDH enrolled in the Congenital Diaphragmatic Hernia Study Group registry between January 2015 and December 2020. The main outcomes assessed included survival to hospital discharge and preoperative pneumothorax development. The cumulative incidence of pneumothorax was estimated by the Gray test. The Fine and Gray competing risk regression model was used to identify the risk factors for pneumothorax. RESULTS: Data for 2858 neonates with isolated left-sided CDH were extracted; 224 (7.8%) developed preoperative pneumothorax. Among patients with a large diaphragmatic defect, those with pneumothorax had a significantly lower rate of survival to discharge than did those without. The competing risks model demonstrated that a patent ductus arteriosus with a right-to-left shunt flow after birth (hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.21-2.63; p = 0.003) and large defects (HR: 1.65; 95% CI: 1.13-2.42; p = 0.01) were associated with an increased risk of preoperative pneumothorax. Significant differences were observed in the cumulative incidence of pneumothorax depending on defect size and shunt direction (p < 0.001). CONCLUSIONS: Pneumothorax is a significant preoperative complication associated with increased mortality in neonates with CDH, particularly in cases with large defects. Large diaphragmatic defects and persistent pulmonary hypertension were found to be risk factors for preoperative pneumothorax development. LEVEL OF EVIDENCE: LEVEL â ¢ Retrospective Comparative Study.

The COL4A1 (collagen Type 4 alpha1) pathogenic variant is associated with porencephaly and schizencephaly and accounts for approximately 20% of these patients. This gene variant leads to systemic microvasculopathy, which manifests as brain, ocular, renal, and muscular disorders. However, only a few patients with surgical interventions have been reported and the potential surgical risks are unknown. Here, we present the cases of two female patients between 7 and 8 years of age who were diagnosed with the COL4A1 variant and underwent laparoscopy-assisted percutaneous endoscopic gastrostomy (LAPEG) for oral dysphagia. Their primary brain lesions were caused by porencephaly and paralysis, which are caused by multiple cerebral hemorrhages and infarctions, and both patients had refractory epileptic complications. Although LAPEG was successfully performed in both patients without any intraoperative complications, one patient developed alveolar hemorrhage postoperatively and required mechanical ventilation. Thus, careful perioperative management of patients with the COL4A1 variant is important.

OBJECTIVE: Innate immunity plays a vital role in xenotransplantation. A CD47 molecule, binding to the SIRPα expressed on monocyte/macrophage cells, can suppress cytotoxicity. Particularly, the SIRPα contains ITIM, which delivers a negative signal. Our previous study demonstrated that the binding between CL-P1 and surfactant protein-D hybrid (CL-SP-D) with SIRPα regulates macrophages' phagocytic activity. In this study, we examined the effects of human CD47 and CL-SP-D expression on the inhibition of xenograft rejection by neutrophils in swine endothelial cells (SECs). METHODS: We first examined SIRPα expression on HL-60 cells, a neutrophil-like cell line, and neutrophils isolated from peripheral blood. CD47-expressing SECs or CL-SP-D-expressing SECs were generated through plasmid transfection. Subsequently, these SECs were co-cultured with HL-60 cells or neutrophils. After co-culture, the degree of cytotoxicity was calculated using the WST-8 assay. The suppressive function of CL-SP-D on neutrophils was subsequently examined, and the results were compared with those of CD47 using naïve SECs as controls. Additionally, we assessed ROS production and neutrophil NETosis. RESULTS: In initial experiments, the expression of SIRPα on HL-60 and neutrophils was confirmed. Exposure to CL-SP-D significantly suppressed the cytotoxicity in HL-60 (p = 0.0038) and neutrophils (p = 0.00003). Furthermore, engagement with CD47 showed a suppressive effect on neutrophils obtained from peripheral blood (p = 0.0236) but not on HL-60 (p = 0.4244). The results of the ROS assays also indicated a significant downregulation of SEC by CD47 (p = 0.0077) or CL-SP-D (p = 0.0018). Additionally, the suppression of NETosis was confirmed (p = 0.0125) in neutrophils co-cultured with S/CL-SP-D. CONCLUSION: These results indicate that CL-SP-D is highly effective on neutrophils in xenogeneic rejection. Furthermore, CL-SP-D was more effective than CD47 at inhibiting neutrophil-mediated xenograft rejection.

The use of thoracoscopy and laparoscopy in the treatment of congenital diaphragmatic hernias (CDHs) has been recently reported; however, the use of these procedures still remains controversial due to CO2 insufflation and limited working space. In addition, because of difficult techniques, it has not been widely accepted. Among CDH patients, mild cases whose lung is not hypoplastic, and not associated with persistent pulmonary hypertension of the neonate (PPHN) often develop small defects in the diaphragm that can be repaired using "direct closure." Because direct closure does not require as wide an operative field as that needed for patch closure, we repaired CDH through umbilical skin windows in two neonates with mild CDH to minimize the wounds. With the creation of additional radical small incisions, the surgeries were successfully performed without any intra- or postoperative complications, and the wounds were cosmetically pleasing. The repair of CDHs through umbilical skin windows is a feasible and useful approach in neonates with mild CDH.

Congenital pulmonary airway malformation is a rare congenital lung lesion. This report documents the successful application of thoracoscopic segmentectomy in a 1-year-old boy prenatally diagnosed with congenital pulmonary airway malformation. Preoperative imaging studies revealed a microcystic lesion with a region of consolidation in the middle area of the right lung. Elective thoracoscopic resection was performed when the patient was aged 1 year and 4 months. Intraoperatively, the superior segment of the right lower lobe was partially separated from the normal lower lobe by a superior accessory fissure. A solid mass, fused with this segment, shared the visceral pleura. Thoracoscopic segmentectomy was successfully performed, and the patient had an uneventful postoperative course. Histological examination revealed congenital pulmonary airway malformation stocker type 2. Thoracoscopic segmentectomy is a viable surgical option that preserves the normal lung parenchyma in pediatric patients with congenital pulmonary airway malformation.

Congenital pulmonary airway malformation (CPAM) is a developmental malformation that affects the lung parenchyma, especially terminal respiratory bronchioles. This paper reports a case of an infant diagnosed with CPAM who underwent stapleless thoracoscopic lobectomy using Hem-o-Lok clips®. Computed tomography showed cystic pulmonary lesions in the left lower lobe. Thoracoscopic lobectomy was performed at the age of 1 year and 3 months. During surgery, the hilar vasculature was treated using either Hem-o-Lok® clips or a LigaSure vessel sealing system. The lower lobe bronchus was divided using double Hem-o-Lok® clips proximally. The surgery was successfully completed. The patient's postoperative course was uneventful, and there were no complications. This technique can be easily performed as a thoracoscopic lobectomy with the potential benefits of safe and effective procedures for bronchus closure and vascular sealing in the small working space of pediatric patients.
RESUMO
PURPOSE: We examined patient satisfaction with postoperative chest appearance after Nuss procedure and analyzed the factors for postoperative low satisfaction. METHODS: We retrospectively reviewed data of 133 patients who underwent the Nuss procedure from 2000 to 2016. Their medical records, X-rays, and computed tomography scans were evaluated. Haller index and concave rate were used as objective indices of the deformity. The questionnaires were used to evaluate satisfaction with the chest appearance by a linear scale including five markers (1: dissatisfaction, 5: satisfaction). The patients were divided into two groups: the low satisfaction (score = 1, 2) and the high satisfaction (score = 3-5). RESULTS: The median age during the Nuss procedure was 7.6 (interquartile range, 5.8-12.8) years. Out of 133, 65 patients replied, and the mean postoperative satisfaction score was 3.8 ± 0.2. Out of the 65 respondents, 16 patients (24.6%) were classified as low satisfaction group. Haller index and concave rate were significantly higher and the previous instances of chest operation history were more frequent in the low satisfaction group than in the high satisfaction group, although there was no significant intergroup difference in terms of the postoperative concave rate. CONCLUSIONS: Severe deformity and previous chest operation history were considered to be factors for low satisfaction.

BACKGROUND: The appropriate timing of liver transplantation (LT) in patients with biliary atresia (BA) who survived with their native livers until adolescence remains controversial. The liver-spleen volume ratio (LSR) has been reported to be efficacious in predicting the prognosis of chronic liver disease. We investigated whether LSR could predict long-term native liver prognosis and serve as an indication for LT in patients with BA. METHODS: Patients with BA who survived with their native liver until the age of 15 years were included. These patients were classified into 2 groups. The unfavorable prognosis group included patients who underwent or were awaiting LT or developed complications such as refractory cholangitis or gastrointestinal bleeding due to esophagogastric or intestinal varices. The favorable prognosis group included patients who survived with their native liver without complications. We compared the 2 groups regarding LSR, hematological, and histologic data. RESULTS: Of 19 patients, 8 were in the unfavorable prognosis group, and 11 were in the favorable prognosis group. LSR was significantly lower in the unfavorable prognosis group (P = .009). Analysis of the receiver operating characteristic curve showed that the area under the curve of the LSR was 0.891, which was higher than the area under the curve of liver fibrosis markers. The optimal LSR cut-off value for predicting poor native liver prognosis was 1.97, with a sensitivity of 75.0% and a specificity of 87.5%. CONCLUSIONS: The LSR reflects splenomegaly and liver atrophy. The LSR might be a reliable predictor of native liver prognosis and could guide decisions about LT in patients with BA.
