    Background: Some neuroblastoma (NB) cases are suitable for minimally invasive surgery (MIS), but indication and technical issue are unclear. We assessed the current status of MIS for abdominal NB after mass screening period in Japan. Methods: Preliminary questionnaires requesting the numbers of NB cases that underwent MIS from 2004 to 2016 were sent to 159 Japanese institutes of pediatric surgery. The secondary questionnaires were then sent to the institutions that reported MIS cases of NB in order to collect detailed data. Results: One hundred and thirty-four (84.2%) institutions responded to the preliminary questionnaires, and 83 (52.2%) reported managing operative cases. The total number of operative cases was 1496. MIS was performed for 175 (11.6%) cases, of which the completed forms of 140 patients were returned, including 100 abdominal NB cases. The male/female ratio was 51/49. Forty-seven cases underwent a laparoscopic biopsy, and 2 (4.3%) cases were converted to laparotomy due to bleeding. Sixty-five cases underwent MIS for radical resection, and 7 (10.8%) were converted to laparotomy. The reasons for open conversion were bleeding and severe adhesion. Regarding open conversion, there were no significant relationships between conversion and neo-adjuvant chemotherapy, biopsies, stage, size, or MYCN amplification. We found no relationship between resectability and vascular encasement in this study. There was relationship between the resected tumor size and the patients’ height, which was expressed using the following formula: y= 0.0316 x+ 1.4812 (x, patients height, y, tumor size; p = 0.004219, SE: 1.55566). Postoperative complications after radical resection were recognized in 7 (10.8%) cases. Conclusions: MIS was performed in limited cases of abdominal NB. A laparoscopic biopsy with careful attention to bleeding is feasible. The resected tumor size was shown to correlate with the patients’ height. Tumor size within 6 cm of maximum diameter can be resected safely.

    Purpose: Tracheomalacia (TM) is a frequent complication after esophageal atresia (EA) repair. This study aimed to review patients who underwent aortopexy for TM after EA repair and to compare their imaging features. Methods: The patients who underwent thoracoscopic EA repair and contrast-enhanced computed tomography (CECT) at our hospital between 2013 and 2020 were retrospectively reviewed. The ratio of the lateral and anterior–posterior diameter of the trachea (LAR) where the brachiocephalic artery (BCA) crosses the trachea was defined. The LAR of the patients who underwent CECT for asymptomatic pulmonary disease was set as a normal reference. The Z-score of each LAR was calculated and compared between the patients that did or did not undergo aortopexy. Results: A total of 51 patients represented the controls, 5 patients underwent aortopexy, and 12 patients were discharged without surgery. The mean LARs in the patients who underwent aortopexy, did not undergo aortopexy, and controls were 3.54, 1.54, and 1.15, respectively. The mean Z-score of the aortopexy group was 21.2. After successful aortopexy, each patient’s LAR decreased to < 1.5. Conclusion: Aortopexy was preferred if the trachea was compressed by the BCA. The LAR is a useful indicator for predicting the therapeutic effect of aortopexy.

    Background: Minimally invasive surgery (MIS) is appropriate for the treatment of some neuroblastomas (NBs); however, the indications and technical issues are unclear. This study aimed to clarify the current status of MIS for mediastinal NB in Japan. Methods: Preliminary questionnaires requesting the numbers of neuroblastoma cases in which MIS was performed from 2004 to 2016 were sent to 159 Japanese institutes of pediatric surgery. Secondary questionnaires were sent to institutions with MIS cases to collect detailed data. Results: One hundred thirty-four (84.2%) institutions returned the preliminary questionnaire and 83 institutions (52.2%) reported a total of 1496 operative cases. MIS was performed for 175 (11.6%) cases. Among the 175 cases, completed forms of 140 patients were returned and 40 (male, n = 28; female, n = 12) cases had mediastinal NB. Fourteen patients received thoracoscopic biopsy, none were converted to thoracotomy. Twenty-eight patients received MIS for radical resection, none were converted to thoracotomy. Perioperative complications (Horner’s syndrome) were recognized after radical resection in one (2.5%) case. Conclusions: MIS was performed in a limited number of mediastinal NB cases. A thoracoscopic approach would be feasible for mediastinal NB.

    Purpose: The features of right-sided congenital diaphragmatic hernias (RCDHs) are quite different from those of left-sided CDHs (LCDHs). We have summarized the features of RCDHs experienced in our institution. Methods: This retrospective study analyzed the cases of patients with CDH registered at our institution between 2011 and 2020. Defects on each side were compared based on prenatal diagnosis, medical treatment, type of surgery, and outcomes. Results: A total of 101 patients underwent surgery at our institution during the neonatal period, and 11 had RCDHs. RCDHs and LCDHs were significantly different in terms of extracorporeal membrane oxygenation (36% vs. 6%, p = 0.002), patch repair (81% vs. 28%, p < 0.001), recurrence rate (36% vs. 11%, p = 0.022), and length of hospital stay (117 days vs. 51 days, p = 0.012). The severity of the fetal diagnosis did not reflect postnatal severity. All patients with RCDH survived to discharge, and there was no significant difference in survival rate between the right and left sides. Conclusion: Neonates with RCDH required more intensive treatments; however, the survival rate was comparable between RCDH and LCDH. RCDH was significantly different from LCDH and an optimal treatment strategy for RCDHs should be established.

    Purpose: Minimally invasive examinations are particularly important in pediatric patients. Although the significance of urinary N1,N12-diacetylspermine (DiAcSpm) as a tumor marker (TM) has been reported in many types of adult cancers, its usefulness in pediatric cancers has not been reported. This may be due to urinary DiAcSpm level variations with age. This study aims to measure the normal levels of urinary DiAcSpm in healthy individuals and investigate its usefulness as a TM in childhood cancer. Methods: Urinary samples were collected from pediatric patients with and without cancer. The urinary DiAcSpm levels were measured, and the values were compared. Results: A total of 32 patients with cancer and 405 controls were enrolled in the study. Of the 32 patients, 13 had neuroblastoma, 9 had malignant lymphoma (ML), and 10 had leukemia. In the control group, the urinary DiAcSpm values markedly fluctuated among those with young age, especially infants; meanwhile, the values converged among those aged roughly 10 years and above. The sensitivity of DiAcSpm was significantly different among the three types of cancers: neuroblastoma (30.8%), ML (77.8%), and leukemia (40%). Conclusion: The urinary DiAcSpm value is a useful TM for both screening and follow-up of ML.

    Background: Most studies reporting the outcomes of laparoscopic ovarian prolapsed hernia operations with large sample sizes are based on intracorporeal closure, while studies on extraperitoneal closure have limited sample sizes. We proactively used the single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) technique and obtained favorable outcomes, which we report in this paper. Methods: We retrospectively reviewed patients who had undergone laparoscopic surgery for inguinal hernia at our institution. They were retrospectively classified into two groups based on the pre- or intraoperative diagnosis of hernia with a prolapsed ovary, namely the prolapse group and the non-prolapse group, respectively. The data were statistically analyzed and p < 0.05 was considered statistically significant. Results: A total of 771 subjects underwent SILPEC during the study period, including 400 girls. Among them, 63 girls were diagnosed with an ovarian prolapsed hernia. SILPEC was successfully performed through a single port in all cases, with a single exception, in whom the forceps was inserted directly through the right lower quadrant to pull up the ovary. The duration of surgery in the prolapse group was not higher than that in the non-prolapse group. During the SILPEC surgery, the ovaries were successfully reverted into the abdominal cavity by external compression of the inguinal area alone in 38 of the 63 patients. In the remaining 25 cases, the ovaries were reverted into the abdominal cavity by external compression of the inguinal area and traction of the round ligament with forceps. None of these cases failed to return to the ovaries. Conclusion: Our study results indicate that SILPEC may be performed safely for the treatment of ovarian prolapsed inguinal hernia. Since the ovary and fallopian tube are close to the internal inguinal ring due to the short round ligament, the procedure requires careful suturing with traction of the round ligament.

    Background: Endoscopic variceal ligation (EVL) is a widely accepted treatment for esophagogastric varices in patients with portal hypertension (PHT). It is used for urgent treatment and prophylactic treatment of esophagogastric varices in pediatric as well as adult patients. However, major life-threatening adverse events such as early rebleeding can occur. Although early rebleeding after EVL among children and adolescents has been reported, the risk factors remain obscure. This study evaluated the risk factors for early rebleeding after EVL in children and adolescents. Methods: The subjects were children and adolescents (<18 years) with PHT who underwent EVL for esophagogastric varices. Early rebleeding was defined as hematemesis, active bleeding, or blood retention in the stomach, confirmed by esophagogastroduodenoscopy from 2 h to 5 days after EVL. Results: A total of 50 EVL sessions on 22 patients were eligible for this study. There were four episodes of early rebleeding. No other major adverse event has occurred. Multivariate analysis showed that EVL implemented at cardiac varices just below the esophagogastric junction (EGJ), within 5 mm from the EGJ, is the independent factor for a higher risk of early rebleeding: odds ratio 18.2 (95% confidence interval: 1.40–237.0), P = 0.02. Conclusions: Children and adolescents who undergo EVL for cardiac varices just below the EGJ have a higher risk of early rebleeding than those who do not.

    Purpose: To investigate late complications after surgery for congenital biliary dilatation (CBD). Methods: We retrospectively reviewed the patients treated for late postoperative complications of extrahepatic bile duct resection with bilioenteric anastomosis for CBD at our hospital between 1999 and 2019. Results: Twenty-seven complications, including bile duct stenosis with (n = 19) or without (n = 3) hepatolithiasis, remnant intrapancreatic bile duct (n = 2), intestinal obstruction (n = 2), and refractory cholangitis (n = 1) were treated in 26 patients. The median age at radical surgery and the initial treatment of complications was 3 years, 2 months and 14 years, 5 months, respectively. The median period from radical surgery to initial treatment of complications was 7 years, 1 month. Before 2013, bile duct stenosis was initially treated with bile duct plasty (n = 11) or hepatectomy (n = 3), and 71.4% (n = 10) of patients needed further treatment; after 2013, double-balloon endoscopic retrograde cholangiography (DBERC) was used (n = 8), and 25% (n = 2) of patients needed further treatment. Patients with remnant intrapancreatic bile duct, intestinal obstruction, and refractory cholangitis required surgery. Conclusion: Long-term follow-up is necessary after surgery for congenital biliary dilatation. DBERC is thus considered to be useful for bile duct stenosis management.

    <p>A 21-month-old girl with chief complaints of vomiting and fever was admitted to a hospital and diagnosed as having congenital biliary dilatation. Magnetic resonance imaging performed on the sixth day of hospitalization revealed bile duct perforation, and the patient was transferred to our department for further treatment. A perforation approximately 2 cm in diameter was found at the confluence of the common bile duct and cystic duct. We concluded that biliary drainage and repair of the perforation would not improve her pathophysiology. Therefore, laparoscopic one-stage radical surgery was performed. In addition, bile duct plasty was performed to treat the severe intrahepatic bile duct membranous stenosis that were observed in the right and left bile ducts of the hepatic hilum. The patient was discharged without complications on the tenth postoperative day.</p><p>Two-stage surgery is the recommended treatment method for congenital biliary dilatation with biliary perforation. However, in recent years, there have been few reports showing that one-stage open radical surgery is useful. In this case, we successfully performed laparoscopic one-stage radical surgery for congenital biliary dilatation with biliary perforation. If laparoscopic radical surgery for congenital biliary dilatation is established at the institution, and the patient is in good general condition, laparoscopic one-stage radical surgery may be an effective modality for treating this condition.</p>

    Hereditary leiomyomatosis and renal cell cancer (HLRCC) is caused by heterozygous germline variants in the fumarate hydratase (FH) gene and is associated with increased susceptibility to cutaneous leiomyomas, uterine leiomyomas, and renal cell carcinoma (RCC). HLRCC-associated RCC usually occurs in the middle age, with the median age being 40–44 years. This report describes a seven-year-old (84-month-old) male who developed a large right kidney tumor with multiple cystic lesions that contained enhanced solid components. There was no evidence of distant metastasis. The male patient underwent right nephrectomy and has been recovering well without metastasis or recurrence. Pathological examination revealed that tumor cells with relatively prominent nucleoli and surrounded by halos, were located in a limited area. Immunohistochemical staining was negative for FH. Whole-exome sequencing identified his germline variant in the FH gene and its loss of heterozygosity in the tumor. At nine years (114 months) of age, the male patient showed no recurrence of the tumor. This was the youngest-onset case of HLRCC-associated RCC to date. This report may affect the starting age for future RCC-surveillance programs for patients with HLRCC.

    Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. This retrospective study included 28 patients who underwent DBERC (44 procedures) after radical surgery for CBD between January 2011 and December 2019. Strictures were diagnosed as “bile duct strictures” if endoscopy confirmed the presence of bile duct mucosa between the stenotic and anastomotic regions, and as “anastomotic strictures” if the mucosa was absent. The median patient age was 4 (range 0–67) years at the time of primary surgery for CBD and 27.5 (range 8–76) years at the time of DBERC. All anastomotic strictures could be treated with only by 1–2 courses of balloon dilatation of DBERC, while many bile duct strictures (41.2%) needed ≥ 3 treatments, especially those who underwent operative bile duct plasty as the first treatment (83.3%). Although the study was limited by the short follow-up period after DBERC treatment, DBERC is recommended as the first-line treatment for hepatolithiasis associated with biliary and anastomotic strictures in CBD patients, and it can be safely performed multiple times.

    <p>The patient was a newborn female with colonic atresia and gastroschisis. A silo was placed immediately after birth and surgery was scheduled the following day. Adhesive detachment was performed by washing the intestinal tract with saline. The oral and anal segments of the colonic atresia were identified, and functional end-to-end anastomosis was performed. Severe edema precluded the immediate return of the intestines to the abdominal cavity and required ongoing treatment with a silo. The intestines gradually returned to the abdominal cavity during the following week. The abdominal wall was closed on postnatal day 9 by a sutureless method. The patient’s postoperative course was good, and full feeding was initiated on postnatal day 19. The patient was discharged from the hospital on postnatal day 32 and recovered without complications. In cases of gastroschisis with colonic atresia, a two-stage surgical procedure is commonly employed. However, functional end-to-end anastomosis using a linear stapler is also an effective method because anastomoses can be performed without regard to differences in intestinal caliber.</p>

    Urine is a complex liquid containing numerous small molecular metabolites. The ability to non-invasively test for cancer biomarkers in urine is especially beneficial for screening child patients. This study attempted to identify neuroblastoma biomarkers by comprehensively analysing urinary metabolite samples from children. A total of 87 urine samples were collected from 54 participants (15 children with neuroblastoma and 39 without cancer) and used to perform a comprehensive analysis. Urine metabolites were extracted using liquid chromatography/mass spectrometry and analysed by Metabolon, Inc. Biomarker candidates were extracted using the Wilcoxon rank sum test, random forest method (RF), and orthogonal partial least squares discriminant analysis (OPLS-DA). RF identified three important metabolic pathways in 15 samples from children with neuroblastoma. One metabolite was selected from each of the three identified pathways and combined to create a biomarker candidate (3-MTS, CTN, and COR) that represented each of the three pathways; using this candidate, all 15 cases were accurately distinguishable from the control group. Two cases in which known biomarkers were negative tested positive using this new biomarker. Furthermore, the predictive value did not decrease in cases with a low therapeutic effect. This approach could be effectively applied to identify biomarkers for other cancer types.

    Purpose: This study aimed to investigate the negative effects of intestinal obstruction for jaundice-free native liver survival after Kasai portoenterostomy (PE) for biliary atresia (BA). Methods: We retrospectively reviewed the records of patients who underwent PE for BA between 2006 and 2019. We evaluated the postoperative morbidity of intestinal obstruction for up to 2 years after PE and the effects of intestinal obstruction on jaundice-free native liver survival. On the basis of their initial operation, patients were divided into open portoenterostomy (Open-PE) and laparoscopic portoenterostomy (Lap-PE) groups, and morbidity was compared. Results: Of the 87 patients reviewed, 6 (6.9%) patients developed postoperative intestinal obstruction and underwent surgery to relieve the obstruction. The morbidity of early postoperative intestinal obstruction was 1.68 per 10,000 person days. The jaundice-free native liver survival rate among patients who once achieved jaundice-free status after PE was significantly lower in the patients with intestinal obstruction compared to in those without intestinal obstruction (0% vs. 73.8%; RR = 3.81, p = 0.007). No significant differences were seen in postoperative intestinal obstructions between the Open-PE and Lap-PE groups (p = 0.242). Conclusions: Intestinal obstruction negatively impact jaundice-free native liver survival, even in patients who once achieved jaundice-free status after PE for BA.

    Purpose: Although we generally perform thoracoscopic lobectomy for congenital lung cysts (CLCs), we recently began performing thoracoscopic-limited pulmonary resection (segmentectomy or small partial lung resection) on relatively small lesions and on lesions involving multiple lobes. Our study aimed to determine the therapeutic outcomes of thoracoscopic CLC surgery. Methods: We retrospectively reviewed patients aged ≤ 18 years who underwent their first CLC surgery at our facility between 2013 and 2020. Results: A comparison between patients < 4 months old and those ≥ 4 months old showed no significant difference in operating time or incidence of complications. Blood loss volume (mL/kg) was significantly greater in patients < 4 months old and in patients who had undergone semi-urgent or urgent surgery. Operating time and postoperative complications were not increased in semi-urgent or urgent surgeries. There was no significant difference in operating time, blood loss volume, or postoperative complications between patients with a preoperative history of pneumonia and patients with no such history. Conclusion: In most patients, thoracoscopic surgery for CLC was safely performed. Limited pulmonary resection is considered difficult to perform thoracoscopically in children, but can be safely performed using new devices and navigation methods. Level of evidence: III.

    Purpose: One of the main causes of stricture at hepaticojejunostomy site after surgery for congenital biliary dilatation is inflammation or infection associated with bile leak. The aim of this study was to determine the risk factors and outcomes of bile leak after laparoscopic surgery. Methods: We retrospectively reviewed the demographics and outcomes of patients who underwent laparoscopic surgery for congenital biliary dilatation between September 2013 and December 2019. Data from patients with bile leak were compared to data from patients without bile leak. Results: Fourteen of 78 patients had bile leak. Hepatic duct diameter at anastomosis was the only risk factor of bile leak. Patients with the diameter ≤ 10 mm had higher incidence of bile leak than in patients with the diameter > 10 mm (P = 0.0023). Among them, bile leak occurred more frequently in patients operated on by non-qualified surgeons based on the Japan Society for Endoscopic Surgery endoscopic surgical skill qualification system than by qualified surgeons (P = 0.027). However, none of the patients with bile leak developed anastomotic stricture afterwards. Conclusion: Although good technical skill is necessary to avoid bile leak in narrow hepatic duct cases (≤ 10 mm), slight bile leak may not result in anastomotic stricture.

    By developing an application and using one-to-many mobile telemedicine to securely link medical sites, we aimed to solve pediatric surgery medical infrastructure and at the same time spread and develop highly specialized telemedicine support. Many doctors can use the application to create a situation where dispersed cases in each region are aggregated in one place (one-to-many remote video conference, image sharing is possible on a smartphone). Can be shared in real time, participate in the consideration of treatment policy, and exchange opinions. We have started to provide highly specialized telemedicine support, which is available 24 hours a day, by securely linking medical fields with desired doctors and hospitals in Japan. The effective use of the system has made it possible to virtually consolidate a specialist with valuable cases.

    Lymphocytes of 71 resected human bowels were examined using flow cytometry. Type 3 innate lymphoid cells (ILC3), which is known to regulate bowel immunity, was detected in all specimens. However, the percentage of ILC3 was not constant according to the condition of patients, e.g. gestational week and disease. Studying the bowel specimens of emergency laparotomy in human neonates, we also investigated the differences in gene expression between necrotizing enteritis and non-necrotic intestinal perforation. We studied the gene expression on a cell-by-cell basis of about 10,000 cells per each case, so we can assess what cells were specifically showing abnormal responses. To date, there have been no reports of gene expression analysis on a cell-by-cell basis. In necrotizing enteritis, T cells were dominant and pathways concerning inflammation, e.g. MYC targets, mTORC1 signaling, TNFA signaling were activated. In non-necrotic intestinal perforation, innate monocytic cells were the major.
