RESUMO
PURPOSE: This study aimed to clarify surgical complications associated with open surgery for congenital diaphragmatic hernia (CDH). METHODS: We performed an exploratory data analysis of the clinical characteristics of surgical complications of neonates with CDH who underwent laparotomy or thoracotomy between 2006 and 2021. Data of these patients were obtained from the database of the Japanese CDH Study Group. RESULTS: Among 1,111 neonates with left or right CDH, 852 underwent open surgery (laparotomy or thoracotomy). Of these 852 neonates, 51 had the following surgical complications: organ injury (n = 48; 6% of open surgeries); circulatory failure caused by changes in the organ location (n = 2); and skin burns (n = 1). Injured organs included the spleen (n = 30; 62% of organ injuries), liver (n = 7), lungs (n = 4), intestine (n = 4), adrenal gland (n = 2), and thoracic wall (n = 2). Fourteen of the patients who experienced organ injury required a blood transfusion (2% of open surgeries). The adjusted odds ratio of splenic injury for patients with non-direct closure of the diaphragm was 2.2 (95% confidence interval, 1.1-4.9). CONCLUSION: Of the patients who underwent open surgery for CDH, 2% experienced organ injury that required a blood transfusion. Non-direct closure of the diaphragmatic defect was a risk factor for splenic injury.

PURPOSE: This study aimed to investigate the incidence of severe surgical complications among children with hepatoblastoma, identify their risk factors, and evaluate the influence of surgical complications on long-term outcomes. METHODS: Children with hepatoblastoma who underwent liver resection at our hospital between September 1992 and January 2023 were included in this study. Clinical data were retrospectively reviewed, and patients were categorized into complication and non-complication groups based on the need for radiological or surgical interventions or massive intraoperative blood loss (> 80 mL/kg). RESULTS: Out of the 40 patients, 9 experienced severe complications (massive blood loss, n = 7; bile leakage, n = 3; and common bile duct stricture, n = 1). The participation of experienced liver surgeons was significantly greater in the non-complication group than in the complication group. The median duration from surgery to the start of postoperative chemotherapy was significantly shorter in the non-complication group than in the complication group. The overall 5-year survival rate was significantly higher in the non-complication group than in the complication group. CONCLUSION: Severe surgical complications were associated with a worse prognosis. An experienced liver surgeon should participate in technically demanding liver resections.
RESUMO
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.

BACKGROUND: Tumor recurrence, anorectal and urinary dysfunction, and lower limb dysfunction after surgery are observed in infantile sacrococcygeal teratoma (SCT). In this paper, a multi-institutional retrospective observational study was conducted to clarify the long-term functional prognosis in Japan. METHODS: This study was conducted using a paper-based questionnaire distributed to 192 facilities accredited by the Japanese Society of Pediatric Surgeons, covering patients who underwent radical surgery at less than 1 year old and who survived for at least 180 days after birth from 2000 to 2019. RESULTS: A total of 355 patients were included in this analysis. Altman type was I-II in 248 and type III-IV in 107, and the median maximum tumor diameter was 6.1 (range: 0.6-36.0) cm. There were 269 mature teratomas, 69 immature teratomas, and 10 malignant tumors. Total resection was performed in 325, subtotal or partial resection in 27, and surgical complications were noted in 54. The median postoperative follow-up was 6.6 (0.5-21.7) years. Eighty-three patients (23.4 %) had functional sequelae, including 62 (17.5 %) with anorectal dysfunction, 56 (13.0 %) with urinary dysfunction, and 15 (4.2 %) with lower limb motor dysfunction. Recurrence occurred in 42 (11.8 %) at a median age of 16.8 (1.7-145.1) months old. Risk factors for dysfunction included preterm delivery, a large tumor diameter, Altman type III-IV, incomplete resection, and surgical complications. Risk factors for recurrence included immature teratoma or malignancy, incomplete resection, and surgical complications. CONCLUSIONS: Postoperative dysfunction was not low at 23.4 %, and 11.8 % of the patients experienced recurrence occurring more than 10 years after surgery, suggesting the need for periodic imaging and tumor markers evaluations in patients with risk factors. It is necessary to establish treatment guidelines for best practice monitoring of the long-term quality of life. LEVEL OF EVIDENCE: Level II Retrospective Study.

PURPOSE: To identify risk factors for delayed oral nutrition in infants with a congenital diaphragmatic hernia (CDH) and its impact on developmental delay at 18 months of age. METHODS: This retrospective single-center cohort study compared the clinical parameters in patients with isolated CDH born and treated at our hospital between 2006 and 2020. We evaluated clinical features significantly related to delayed oral nutrition (defined as taking ≥ 30 days from weaning from mechanical ventilation to weaning from tube feeding). RESULTS: Twenty-six of the 80 cases had delayed oral nutrition. Univariate analyses showed significant differences. Multivariate analyses were performed on the three items of preterm delivery, defect size (over 50% to nearly entire defect), and ventilation for ≥ 9 days. We identified the latter two items as independent risk factors. The adjusted odds ratios were 4.65 (95% confidence interval, 1.27-7.03) and 6.02 (1.65-21.90), respectively. Delayed oral nutrition was related to a significantly higher probability of developmental delay at 18 months (crude odds ratio 4.16, 1.19-14.5). CONCLUSION: In patients with CDH, a large defect and ventilatory management over 9 days are independent risk factors for delayed oral nutrition, which is a potent predictor of developmental delay that requires active developmental care.

PURPOSE: This study aimed to investigate the incidence and clinical factors associated with undescended testes (UDT) in patients with congenital diaphragmatic hernia (CDH). METHODS: We retrospectively reviewed the incidence of UDT in male neonates admitted to our institution and underwent surgery for CDH between January 2006 and December 2022. Patients were divided into two groups based on the presence or absence of UDT, and risk factors for UDT were compared between the two groups. RESULTS: Among the 66 male neonates with CDH, 16 (24.2%) developed UDT. Patients with UDT had a significantly smaller gestational age (p = 0.026), lower birth weight (p = 0.042), and lower Apgar score at 1 min (p = 0.016) than those without UDT. They had a significantly higher incidence of large diaphragmatic defects (p = 0.005), received more patch closures (p = 0.020), had a longer mechanical ventilation period (p = 0.034), and longer hospital stay (p = 0.028). Multiple logistic regression analysis revealed that large diaphragmatic defect was an independent risk factor for UDT (adjusted odds ratio of 3.87). CONCLUSION: CDH and UDT are strongly correlated. In patients with CDH, the incidence of UDT was related not only to patients' prematurity but also to the large diaphragmatic defect. Large diaphragmatic defect is an independent risk factor for UDT in patients with CDH.

BACKGROUND & AIMS: Growth retardation is a common morbidity in infants with severe congenital diaphragmatic hernia (CDH). This study aimed to investigate the appropriate amount of nutrition and nutrient balance in early infants with severe CDH. METHODS: This was a retrospective case-control study. Isolated CDH patients with more than half of the chest wall devoid of diaphragmatic tissue and treated between 2006 and 2022 were included. The patients were divided into positive (n = 16) or negative (n = 8) weight gain velocity groups in early infancy (from 1 to 3 months of age). Clinical variables and amount of nutrition were compared between the two groups. RESULTS: The earlier start of enteral nutrition (EN) and higher replacement rate of the naso-duodenal (ND) tube were observed more frequently in the positive group than in the negative group. Regarding daily intake by both EN and parenteral nutrition (PN), total caloric intake and caloric intake of proteins and lipids were significantly higher in the positive group than in the negative group at 1 month of age. At 2 months, total caloric intake and caloric intake of lipids were significantly higher in the positive group than in the negative group. At 3 months of age, only caloric intake of lipid was significantly higher in the positive group than in the negative group. CONCLUSIONS: The early replacement of the ND tube may contribute to the early start of EN, which may subsequently lead to appropriate nutrient supplementation including adequate lipid administration, resulting in early catch-up growth.

OBJECTIVE: To assess the reliability of pulmonary artery (PA) parameters as a prognostic marker in neonates with isolated left-sided congenital diaphragmatic hernia (IL-CDH). STUDY DESIGN: A retrospective cohort study conducted by the Japanese CDH Study Group (JCDHSG). RESULTS: 323 IL-CDH patients registered with the JCDHSG were included. 272 patients survived to 90 days of age. Right PA (RPA) and left PA (LPA) diameters and pulmonary artery index (PAIndex) at birth were significantly larger in survivors. The cutoff values of RPA and LPA diameters and PAIndex for survival up to 90 days were 3.2 mm, 2.8 mm and 83.7, respectively, and logistic regression analysis showed that these were significantly related to survival. Multiple logistic regression analysis showed that both the PA parameters and liver herniation were significantly related to survival. CONCLUSIONS: The three PA parameters at birth can predict clinical outcomes and are considered as independent risk factors of liver herniation.

This systematic review and meta-analysis aimed to review the optimal timing of delivery at term for neonates with prenatally diagnosed congenital diaphragmatic hernia (CDH). We reviewed the literature up to December 19, 2022 using MEDLINE and the Cochrane Library databases. The inclusion criteria were original articles, comparative studies of CDH neonates delivered at an early term (37-38 weeks of gestation) and at full term (39 weeks of gestation or later), and comparative studies investigating outcomes of CDH neonates. Six studies met the inclusion criteria, including 985 neonates delivered at an early term and 629 delivered at full term. The cumulative rate of survival to discharge showed no significant difference between CDH neonates delivered at an early term (395/515; 76.7%) or at full term (345/467; 73.9%) (risk ratio [RR] 1.01; 95% confidence interval [CI], 0.89-1.16; p = 0.85). Furthermore, the number of neonates requiring oxygen therapy at discharge was not significantly different between CDH neonates delivered at an early term (32/370; 8.6%) and at full term (14/154; 9.1%) (RR, 0.99; 95% CI, 0.36-2.70; p = 0.99). Therefore, the optimal timing of delivery at term for neonates with CDH remains unclear.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a severe congenital disease. Some CDH infants suffer from gastro-esophageal reflux disease (GERD), even after surgical correction of gastric position. A transpyloric tube (TPT) is inserted into CDH patients under direct observation intraoperatively in some hospitals in Japan to establish early enteral feeding. This strategy avoids gastric expansion to maintain a better respiratory condition. However, it is unclear whether the strategy has a secure effect for patient prognosis. This study aimed to evaluate the effectiveness of intraoperative TPT insertion on enteral feeding and postoperative weight gain. METHODS: The Japanese CDH Study Group database was used to identify infants with CDH born between 2011 and 2016, who were then divided into two groups: the TPT group and gastric tube (GT) group. In the TPT group, infants underwent intraoperative TPT insertion; postoperative insertion/extraction of TPT was irrelevant to the analysis. Weight growth velocity (WGV) was calculated using the exponential model. Subgroup analysis was performed using Kitano's gastric position classification. RESULTS: We analyzed 204 infants, of which 99 and 105 were in the TPT and GT groups, respectively. Enteral nutrition (EN) in the TPT and GT groups was 52 ± 39 and 44 ± 41 kcal/kg/day (p = 0.17) at age 14 days (EN14), respectively, and 83 ± 40 and 78 ± 45 kcal/kg/day (p = 0.46) at age 21 days (EN21), respectively. WGV30 (WGV from day 0 to day 30) in the TPT and GT groups was 2.3 ± 3.0 and 2.8 ± 3.8 g/kg/day (p = 0.30), respectively, and WGV60 (WGV from day 0 to day 60) was 5.1 ± 2.3 and 6.0 ± 2.5 g/kg/day (p = 0.03), respectively. In infants with Kitano's Grade 2 + 3, EN14 in the TPT and GT groups was 38 ± 35 and 29 ± 35 kcal/kg/day (p = 0.24), respectively, EN21 was 73 ± 40 and 58 ± 45 kcal/kg/day (p = 0.13), respectively, WGV30 was 2.3 ± 3.2 and 2.0 ± 4.3 g/kg/day (p = 0.76), respectively, and WGV60 was 4.6 ± 2.3 and 5.2 ± 2.3 g/kg/day (p = 0.30), respectively. CONCLUSION: Intraoperative TPT insertion did not improve nutritional intake and WGV30. WGV60 in TPT was less than that in GT. In Grade 2 + 3 subgroup analysis, TPT also had no advantage. We could not recommend routine TPT insertion at surgery. LEVEL OF EVIDENCE: III.

OBJECTIVES: To evaluate the survival and intact-survival rates among preterm infants with congenital diaphragm hernia (CDH). STUDY DESIGN: Multicenter retrospective cohort study of 849 infants born between 2006 and 2020 at 15 Japanese CDH study group facilities. Multivariate logistic regression analysis adjusted using inverse probability treatment weighting (IPTW) method was used. We also compare trends of intact-survival rates among term and preterm infants with CDH. RESULTS: After adjusting using the IPTW method for CDH severity, sex, APGAR score at 5 min, and cesarean delivery, gestational age and survival rates have a significantly positive correlation [coefficient of determination (COEF) 3.40, 95% confidence interval (CI), 1.58-5.21, p value <0.001] and higher intact-survival rate [COEF 2.39, 95% CI, 1.73-4.06, p value 0.005]. Trends of intact-survival rates for both preterm and term infants had significantly changed, but improvement in preterm infants was much smaller than in term infants. CONCLUSION: Prematurity was a significant risk factor for survival and intact-survival among infants with CDH, regardless of adjustment for CDH severity.

PURPOSE: This study aimed to evaluate the feasibility and safety of laparoscopic resection of abdominal neuroblastoma by comparing operative and long-term oncologic outcomes between open and laparoscopic surgeries. METHODS: This single-center retrospective study included patients who underwent laparoscopic tumor resection, between January 2000 and June 2021, with a maximum tumor diameter of ≤ 60 mm and without image-defined risk factors (IDRFs) at surgery. Data from 35 abdominal neuroblastoma resections were reviewed and compared between the laparotomy and laparoscopic groups. RESULTS: Nineteen patients underwent laparotomy and 16 had laparoscopic tumor resection. All laparoscopic surgeries achieved complete resection without conversion to open surgery. Median blood loss was significantly lower in the laparoscopic group (0.6 mL/kg) than in the laparotomy group (8.4 mL/kg) (P < 0.0001). There were two locoregional recurrences in the laparoscopic group and two metastatic recurrences in the laparotomy group. Five-year overall survival was 93.8% in both groups. CONCLUSION: Laparoscopic resection of abdominal neuroblastomas in children is a feasible and safe procedure for tumors ≤ 60 mm in diameter with no IDRFs at surgery, with long-term outcomes equivalent to laparotomy.

A 4-year-old girl was admitted to our hospital because of precocious puberty. Radiologic findings revealed a fist-sized solid tumor in the left ovary without ascites, peritoneal dissemination, and distant metastasis. The patient underwent left salpingo-oophorectomy without spillage. The size of the excised tumor was 10.0×9.0×4.8 cm. On pathologic examination, the tumor was diagnosed as an ovarian steroid cell tumor, not otherwise specified. In the present case, although the diameter of the tumor (>7 cm) and three mitoses per 10 high-power fields represented some potential for malignancy, we opted for careful observation without chemotherapy as the tumor was of clinical stage Ia.

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: Mortality prediction of congenital diaphragmatic hernia (CDH) is essential for developing treatment strategies, including fetal therapy. Several researchers have reported prognostic factors for this rare but life-threatening condition; however, the optimal combination of prognostic factors remains to be elucidated. OBJECTIVES: This study aimed to develop the most discriminative prenatal and postnatal models to predict the mortality of infants with an isolated left-sided CDH. METHODS: This multi-institutional retrospective cohort study included infants with CDH born at 15 tertiary hospitals of the Japanese CDH Study Group between 2011 and 2016. We developed multivariable logistic models with every possible combination of predictors and identified models with the highest cross-validated area under the receiver operating characteristic curve (AUC) for prenatal and postnatal predictions. RESULTS: Among 302 eligible infants, 44 died before discharge. The prenatal mortality prediction model was based on the observed/expected lung area to head circumference ratio (O/E LHR), liver herniation, and stomach herniation (AUC, 0.830). The postnatal mortality prediction model was based on O/E LHR, liver herniation, and the lowest oxygenation index (AUC, 0.944). CONCLUSION: Our models can facilitate the prenatal and postnatal mortality prediction of infants with isolated left-sided CDH.

PURPOSE: To develop a predictive score for small diaphragmatic defects in infants with congenital diaphragmatic hernia (CDH) for determining thoracoscopic surgery indication. METHODS: The Japanese CDH Study Group cohort was randomly divided into derivation (n = 397) and validation (n = 396) datasets. Using logistic regression, a prediction model and weighted scoring system for small diaphragmatic defects were created from derivation dataset and validated with validation dataset. RESULTS: Six weighted variables were selected: no hydramnios, 1 point; 1 min Apgar score of 5-10, 1 point; apex type of the lung (left lung is detected radiographically in apex area), 1 point; oxygenation index < 8, 1 point; abdominal nasogastric tube (tip of the nasogastric tube is detected radiographically in the abdominal area), 2 points; no right-to-left flow of ductus arteriosus, 1 point. In validation dataset, rates of small diaphragmatic defects for Possible (0-3 points), Probable (4-5 points), and Definite (6-7 points) groups were 36%, 81%, and 94%, respectively (p < 0.001). Additionally, sensitivity, specificity, positive predictive value, and C statistics were 0.78, 0.79, 0.88, 0.76, and 0.45, 0.94, 0.94, 0.70 for Probable and Definite groups, respectively. CONCLUSION: Our scoring system effectively predicted small diaphragmatic defects in infants with CDH.

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.

PURPOSE: The prenatal diagnosis of the stomach position in congenital diaphragmatic hernia (CDH) has been a reliable prognostic factor, but few studies have focused on the postnatal position. We therefore evaluated the significance of the nasogastric (NG) tube position just after birth. METHODS: The Japanese CDH Study Group database enrolled 1037 CDH neonates over 15 years. In our multicenter retrospective study, 464 cases of left-sided isolated CDH with prenatal diagnoses were divided into two groups: NG tube below the diaphragm (BD; n = 190) or above the diaphragm (AD; n = 274). The primary outcome was the 90-day survival rate, and the secondary outcomes were mechanical ventilation duration, hospitalization duration, and recurrence rate. RESULTS: The BD group had a significantly higher 90-day survival rate (98.4 vs. 89.4%, p < 0.001), shorter mechanical ventilation (11 vs. 19 days, p < 0.001), shorter hospitalization (38 vs. 59 days, p < 0.001), and lower recurrence rate (p = 0.002) than the AD group. A multivariate analysis showed that BD (adjusted odds ratio, 3.68; 95% confidence interval 1.02-13.30) was a favorable prognostic factor for the 90-day survival. CONCLUSION: The assessment of the NG tube position revealed it to be a reliable prognostic factor of left-sided isolated CDH. Therefore, it should be included as a routine assessment.

PURPOSE: Fetuses with persistent cloaca are known to develop urine or meconium backflow into the abdominal cavity caused by obstruction of the common channel, thus leading to fetal peritonitis with fetal ascites. We analyzed the impact of prenatal fetal ascites on postnatal clinical features and management. METHODS: This retrospective single-center cohort study was conducted to compare the perinatal parameters of patients with isolated persistent cloaca who were born and treated at our hospital between 1991 and 2021. The clinical features and management of those with and without fetal ascites were compared. RESULTS: Among the 17 eligible patients, fetal ascites were recognized in seven. The occurrence of fetal ascites was significantly related to preterm birth, higher birth weight z-score, birth via emergency cesarean delivery, low Apgar scores at 1 min and 5 min, higher C-reactive protein levels at birth, longer duration of oxygen administration, the need for a urinary drainage catheter at initial discharge, and shorter neonatal hospital stays. CONCLUSIONS: The postnatal management of patients with persistent cloaca with fetal ascites differed significantly from that of patients without fetal ascites. For patients with unexplained fetal ascites, magnetic resonance imaging may be helpful for determining the definite diagnosis of persistent cloaca.
