RESUMEN

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.

RESUMEN

PURPOSE: Hepatocyte mitochondrial morphology and gene expression were compared between biliary atresia (BA), infantile cholestasis (IC), and normal liver (NL) as prognostic indicators. METHODS: Specimens of liver at portoenterostomy (PE) for BA, from intrahepatic bile duct paucity patients for IC, and from choledochal cyst or hepatoblastoma patients for NL were collected prospectively (P) beginning in 2021 (P-BA = 11, P-IC = 9, P-NL = 7) and retrospectively (R) from paraffin-embedded tissue going back to 1981 (R-BA = 25, R-IC = 9, R-NL = 4). The P-cohort had transmission electron microscopy (TEM) to image mitochondria, immunoblotting for heat shock protein 60 (HSP60), and quantitative PCR (qPCR) for HSP60 and mitochondrial functional genes. Both cohorts had immunofluorescence for HSP60 quantified as a ratio to albumin-positive hepatocytes (ALB) with HSP60/ALB<1.0 as a cutoff limit using ImageJ. RESULTS: HSP60 was significantly lower in BA/IC than NL on qPCR (BA: p < 0.01, IC: p < 0.05) and lower in BA than IC/NL on immunoblotting (p < 0.05). HSP60/ALB was significantly lower in BA than NL/IC (p < 0.001). Despite BA subjects being matched for types of BA and ages at PE, HSP60/ALB did not correlate with jaundice clearance (JC; T-Bil<1.2 mg/dL) but was significantly higher in native liver survivors (NLS) after PE compared with liver transplant (LTx) cases (p < 0.05) and significantly lower in LTx cases achieving JC than NLS achieving JC (p < 0.05). TEM showed BA had significantly more mitochondrial inclusion bodies (p < 0.05) and significantly larger cristae (p < 0.01) than IC/NL. qPCR in BA showed significant repression of mitochondrial functional genes for mRNA stabilization and energy facilitation. CONCLUSION: HSP60/ALB correlates with NLS after PE for BA. LEVEL OF EVIDENCE: II.

RESUMEN

Aim: To review the indications for rectal mucosal/submucosal biopsy (RMSBx) used for diagnosing Hirschsprung's disease (HD) in pediatric patients. Methods: The medical records of all children between 1 and 15 years old assessed for chronic constipation between 2012 and 2022 were reviewed. Until the end of 2018, enema usage (E+) was a major indication for RMSBx. In 2019, laxative use for 3 months irrespective of enema use was added as an indication (L+). To determine the relevance of enema usage, L+ was subdivided by enema usage into (L+E+) and (L+E-) groups. The effect of changing the indications for RMSBx on the incidence of HD was investigated. Results: Of 562 eligible subjects, E+ = 410, L+ = 152; demographics are similar. RMSBx rate in E+ (E+RMSBx) was 36/410 (8.8%) and in L+ (L+RMSBx) was 42/152 (27.6%;) (P < .05). For L+RMSBx, 15/42 were L+E+ and 27/42 were L+E-. HD incidence in E+RMSBx was 8/36 (22.2%; E+HD) and in L+RMSBx was 13/42 (31.0%; L+HD) (p = ns). In L+RMSBx, HD incidence in L+E+ was 5/15 (33.3%; L+E+HD) and in L+E- was 8/27 (29.6%; L+E-HD) (P = ns). Differences in daily bowel motion frequency 6 months postoperatively were not statistically significant; E+HD (1.75/d) versus L+HD (2.03/d) and L+E+HD (1.60/day) versus L+E-HD (2.31/day). Unassisted voluntary defecation was confirmed 12 months postoperatively in 7/8 (87.5%) E+HD, 11/13 (84.6%) L+HD, 4/5 (80.0%) L+E+HD, and 7/8 (87.5%) L-E-HD; differences were not significant. Laxatives were still required in 2/8 (25.0%) E+HD, 3/13 (23.1%) L+HD, in 1/5 (20.0%) in L+E+HD, and 2/8 (25.0%) L+E-HD; differences were not significant. Conclusion: Incidence of HD was higher in L+HD, but not significantly different suggesting that indications for RMSBx have potential to influence incidence of HD and hint that the incidence of HD could actually be higher. Further assessment of additional indications is warranted to diagnose HD with greater accuracy.

RESUMEN

Aims: Retroperitoneoscopic simple nondismembered pyeloplasty (SNDP) with da Vinci Si assistance was developed because of a possible risk for alignment shift after retroperitoneoscopic diamond-shaped bypass pyeloplasty (Diamond-Bypass; DP). Outcomes of SNDP and DP were compared. Materials and Methods: For SNDP, a small longitudinal incision is made on the border of the dilated pelvis and narrowed ureter at the ureteropelvic junction (UPJ). Extending this incision toward the pelvis allows identification of mucosa while maintaining the integrity of surrounding tissues that are so thin and fragile that they will not influence lumen alignment. Data for DP were obtained from a previously published article. Results: For SNDP (n = 3), mean age at surgery was 2.67 years (range: 1-4), mean operative time was 176 minutes. Mean postoperative Society of Fetal Urology (SFU) grades for hydronephrosis were 1.2, 0.7, and 0.6, 1, 2, and 3 months after stent removal, respectively. Postoperative diethylenetriaminepentaacetic acid (DTPA) was normal (n = 3). For DP (n = 5) mean age at surgery was 4.3 years (range: 1-14), mean operative time was 189 minutes. Mean postoperative SFU grades were 2.8, 2.2, and 1.6, respectively. Postoperative DTPA was normal (n = 4) and delayed (n = 1). All SNDP and DP were asymptomatic by 3 months after stent removal. Conclusion: Both SNDP and DP have favorable outcomes. If the UPJ is located at the lowest end of the renal pelvis, SNDP may improve hydronephrosis more quickly.

RESUMEN

Background: Following on from an earlier study published in 2008 about left pulmonary artery (LPA) flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia (CDH) and the ratio of LPA to right pulmonary artery (RPA) diameters being a simple and reliable indicator for commencing nitric oxide (NO) therapy, the ratio of LPA:RPA diameters (PA ratio or PAR) was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH better. Methods: Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to survival. Data obtained retrospectively for subject demographics, clinical course, LPA/RPA diameters, and PAR were compared between survivors and non-survivors. The value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic (ROC) curve analysis. Results: Of 65 subjects, there were 54 survivors (82.3%) and 11 non-survivors (17.7%); 7 of 11 non-survivors died before surgical repair could be performed. Mean PAR for survivors (0.851±0.152) was significantly higher than for non-survivors (0.672±0.108) (p=0.0003). Mean PAR for non-survivors was not affected by surgical repair. Characteristics of survivors were: LPA ≥2 mm (n=52 of 54; mean PAR=0.866±0.146) and RPA ≥3 mm (n=46 of 54; mean PAR=0.857±0.152). Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean PAR. ROC curve cut-off for PAR was 0.762. Subjects with high PAR (≥0.762) required high-frequency oscillatory ventilation/NO less than subjects with low PAR (<0.762) (p=0.0244 and p=0.0485, respectively) and subjects with high PAR stabilized significantly earlier than subjects with low PAR (1.71±0.68 days vs 3.20±0.87 days) (p<0.0001). Conclusions: PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

RESUMEN

BACKGROUND: Dysplasia, carcinoma in situ, and other malignant transformation or premalignant/malignant histopathology (PMMH) seem uncommon in pediatric choledochal cyst (CC). A literature review and the authors' experience are presented. METHODS: All reports about PMMH in CC patients 15 years old or younger published in English and all cases of PMMH in specimens excised from CC patients 15 years old or younger by the authors were reviewed. RESULTS: Of 20 published reports, PMMH was adenocarcinoma (n = 4), sarcoma (n = 4), and dysplasia (n = 12). Treatment for malignancies was primary pancreaticoduodenectomy (PD; n = 2) or cyst excision/hepaticojejunostomy (Ex/HJ; n = 6). Outcomes at the time of writing for malignancies: 2 deaths, 4 survivors after follow-up of 2 years, and 2 lost to follow-up. No dysplasia case has undergone malignant transformation. The authors have experienced 7 cases of PMMH; adenocarcinoma in situ (AIS; n = 1) and dysplasia (n = 6). CONCLUSIONS: The present study identified the youngest cases of AIS and dysplasia from specimens excised when they were 3 years old and 4 months old, respectively. Both are published for the first time as evidence that PMMH can complicate CC in young patients. Long-term protocolized postoperative follow-up is mandatory when PMMH is diagnosed in pediatric CC.

RESUMEN

PURPOSE: To evaluate common hepatic duct just distal to the HE anastomosis (d-CHD) prospectively for mucosal damage, inflammation, fibrosis, dysplasia, carcinoma in situ, malignant transformation, effects of serum amylase, and symptoms at presentation in CC cases ranging from children to adults. METHODS: Cross-sections of d-CHD obtained at cyst excision 2018-2023 from 65 CC patients; 40 children (< 15 years old), 25 adults (≥ 15) were examined with hematoxylin and eosin, Ki-67, S100P, IMP3, p53, and Masson's trichrome to determine an inflammation score (IS), fibrosis score (FS), and damaged mucosa rate (DMR; damaged mucosa expressed as a percentage of the internal circumference). RESULTS: Mean age at cyst excision ("age") was 18.2 years (range: 3 months-74 years). Significant inverse correlations were found for age and DMR (p = 0.002), age and IS (p = 0.011), and age and Ki-67 (p = 0.01). FS did not correlate with age (p = 0.32) despite significantly increased IS in children. Dysplasia was identified in a 4-month-old girl with cystic CC. Serum amylase was elevated in high DMR subjects. CONCLUSIONS: High DMR, high IS, and evidence of dysplasia in pediatric CC suggest children are at risk for serious sequelae best managed by precise histopathology, protocolized follow-up, and awareness that premalignant histopathology can arise in infancy.

RESUMEN

Objective: The aim of the study is to discuss the efficacy of live vs. remote cadaver surgical training (CST) for minimally invasive surgery (MIS). Methods: A cohort of 30 interns in their first and second years of training were divided into three groups: live observers (n = 12), live participants (n = 6), and remote observers: (n = 12). The interns had the opportunity to either observe or actively participate in two different surgical procedures, namely, laparoscopic lower anterior resection, performed by a colorectal surgical team, and laparoscopic fundoplication, performed by a pediatric surgical team. The procedures were conducted either at a base center or at a remote center affiliated with the institute. Some of the interns interacted directly with the surgical teams at the base center, and others interacted indirectly with the surgical teams from the remote center. All interns were administered questionnaires before and after completion of the CST in order to assess their understanding of various aspects related to the operating room layout/instruments (called "design"), accessing the surgical field (called "field"), understanding of anatomic relations (called "anatomy"), their skill of dissection (called "dissection"), ability to resolve procedural/technical problems (called "troubleshooting"), and their skill in planning surgery (called "planning") according to their confidence to operate using the following scale: 1 = not confident to operate independently; 4 = confident to operate with a more senior trainee; 7 = confident to operate with a peer; and 10 = confident to operate with a less experienced trainee. A p < 0.05 was considered statistically significant. Results: All scores improved after CST at both the base and remote centers. The following significant increases were observed: for remote observers: "field" (2.67→4.92; p < .01), "anatomy" (3.58→5.75; p < .01), "dissection" (3.08→4.33; p = .01), and "planning" (3.08→4.33; p < .01); for live observers: "design" (3.75→6.17; p < .01), "field" (2.83→5.17; p < .01), "anatomy" (3.67→5.58; p < .01), "dissection" (3.17→4.58; p < .01), "troubleshooting" (2.33→3.67; p < .01), and "planning" (2.92→4.25; p < .01); and for live participants: "design" (3.83→6.33; p = .02), "field" (2.83→6.83; p < .01), "anatomy" (3.67→5.67; p < .01), "dissection" (2.83→6.17; p < .01), "troubleshooting" (2.17→4.17; p < .01), and "planning" (2.83→4.67; p < .01). Understanding of "design" improved significantly after CST in live observers compared with remote observers (p < .01). Understanding of "field and "dissection" improved significantly after CST in live participants compared with live observers (p = .01, p = .03, respectively). Out of the 12 remote observers, 10 participants (83.3%) reported that interacting with surgical teams was easy because they were not on-site. Conclusions: Although all the responses were subjective and the respondents were aware that observation was inferior to hands-on experience, the results from both centers were equivalent, suggesting that remote learning could potentially be viable when resources are limited.

RESUMEN

Aims: Early postoperative outcome (EPO) was compared between fully laparoscopic Duhamel-Z (F-Dz) and laparoscopy-assisted Duhamel-Z (A-Dz) anastomoses performed for total colonic aganglionosis (TCA). Methods: EPO was assessed quarterly for the first year after F-Dz/A-Dz using a continence evaluation score (CES) based on stool frequency (motions/day) and stool consistency (0 = liquid, 1 = soft, 2 = formed), presence of anal erosion (0 = severe, 1 = moderate, 2 = mild), and incidence of enterocolitis.Surgical technique involved taking the ileostomy down, dissecting the colon laparoscopically, and preparing the pull-through ileum through the stoma wound. In F-Dz (n = 3), a working port (SILS trocar) was inserted, and laparoscopic retrorectal dissection with forceps used to create a retrorectal tunnel from the peritoneal reflection extending downward as narrow as possible along the posterior wall of the rectum to prevent lateral nerve injury and preserve vascularity. After completing the tunnel, the ileum was pulled-through from an incision on the anorectal line and a Z-shaped ileorectal side-to-side anastomosis performed without a blind pouch. In A-Dz (n = 11), the retrorectal pull-through route was created through a Pfannenstiel incision using blunt manual (finger) dissection along the anterior surface of the sacrum. Results: Subject backgrounds were similar. Mean quarterly data were: frequency (F-Dz: 4.67, 4.67, 4.67, 3.33) vs. (A-Dz: 7.27, 7.09, 6.18, 5.36) p < .05; consistency (F-Dz: 0.33, 0.67, 0.67, 0.67) vs. (A-Dz: 0.27, 0.45, 0.70, 0.73) p = ns; anal erosion (F-Dz: 0.33, 0.33, 0.33, 0.67) vs. (A-Dz: 0.18, 0.36, 0.45, 0.64) p = ns; and enterocolitis (F-Dz: 1 episode in 1/3 cases or 33.3%) vs. (A-Dz: 7 episodes in 6/11 cases or 54.5%) p = ns. Conclusions: Overall, EPO after F-Dz was better than after A-Dz.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIM: Robot (da Vinci Si; Intuitive Surgical, Sunnyvale, CA) assisted retroperitoneoscopic diamond bypass pyeloplasty (R-RDBP) performed for ureteropelvic junction (UPJ) obstruction (n = 5) is presented. METHODS: Patients were placed affected side up and the retroperitoneal space accessed conventionally using 3-4 trocars. The diamond-shaped anastomosis involved incising the lowest part of the renal pelvis 12-15 mm transversely and the ureter distal to the obstruction 10-12 mm longitudinally. The first two sutures were placed retroperitoneoscopically; one from the mid-caudal line of the renal pelvis to the apex of the ureteric incision (the apex of the diamond) and the other from the corner of the incision in the renal pelvis to halfway along the ureteric incision. Trocars were replaced and the robot system docked. The first robot suture was placed between these two sutures, and the anastomosis completed by suturing from posterior to ventral applying minimal tension to keep the anastomosis close to the renal pelvis. All sutures were interrupted absorbable 5-0 monofilament. RESULTS: Mean age at R-RDBP was 4.3 (range: 1-14) years old. Height/weight were average. Preoperative Society for Fetal Urology (SFU) grading was 4.0 in all cases. All repairs were primary and progressed smoothly without perioperative complications; 3/5 had improved appetite postoperatively. Mean SFU grades 1-3 months postoperatively were 2.8, 2.2, and 1.6, respectively. Diuretic renography that was obstructive in all cases preoperatively was normal in four and delayed in one case, postoperatively. CONCLUSION: R-RDBP prevented rotation/kinking of the ureter, enhanced precision of suturing, and maximized the diameter at the anastomosis, facilitating smooth urine flow. LEVEL OF EVIDENCE: LEVEL IV.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIM: To assess mid-/long-term postoperative quality of life (QOL) of esophageal atresia (EA) patients. METHODS: Modified gastrointestinal quality-of-life index surveys were administered to postoperative EA patients who were at least 7 years old at evaluation to assess three topics about general lifestyle (GL), five topics about EA, and four topics about mental health (MH). For MH, caregivers were also interviewed, but separately. Subjects were divided according to age: children (7-12 years old), teenagers (13-19), and adults (20 and over) and compared according to Foker or Kimura elongation (FK) or bougienage stretching (BS). RESULTS: There were 22 patients evaluated. Responses for GL, EA, and MH did not differ significantly between age groups, but MH responses by caregivers for subjects who were children or teenagers scored significantly lower than responses they made themselves. For primary esophageal elongation technique (PET), age at esophagoesophagostomy was significantly higher in FK. Despite FK scoring 15.1 versus 12.4 for BS during EA evaluation, this difference was not statistically significant. CONCLUSION: Changes in QOL responses according to age were unremarkable. However, discrepancies in MH indicate that subjects felt better than their caregivers thought. PET did not appear to influence QOL.

RESUMEN

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.

RESUMEN

AIM: To assess mid-/long-term quality of life (QOL) of total colonic aganglionosis (TCA) patients. METHODS: Modified pre-existing QOL assessment tools for general lifestyle (GL), bowel function (BF), and mental health (MH) were administered to postoperative TCA patients from five institutions, who were at least 7 years old to compare Duhamel (with pouch) and Swenson/Soave (without pouch) techniques between children (Ch 7-12 years old), teenagers (Tn 13-19), and adults (Ad 20 and over). For MH, caregivers were also interviewed, but separately. Maximum scores were 12 for GL/MH and 18 for BF. RESULTS: There were 32 subjects. GL and BF scores increased significantly from Ch (GL 4.8 ± 2.5, BF: 11.3 ± 4.6) to Tn (GL 7.8 ± 2.6, BF 16.2 ± 3.0); scores for MH did not change significantly. Mean caregiver MH scores were significantly lower than mean subject MH scores for all age groups (subject scores: 10.1, 10.7, 10.7 versus caregiver scores: 6.8, 7.8, 8.1 for Ch, Tn, Ad, respectively). PT technique/presence of a pouch did not influence the incidence of enterocolitis or QOL scores. CONCLUSION: MH responses showed subjects felt better than caregivers believed. This discrepancy could cause conflict despite steadily improving GL/BF. QOL was unaffected by PT technique/presence of a pouch.

RESUMEN

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.
