We reviewed the outcomes of meconium peritonitis and evaluated the safety and feasibility of primary radical surgery for meconium peritonitis. A total of 21 cases of meconium peritonitis between 2006 and 2020 were retrospectively reviewed. The patients were classified into two groups based on the type of surgery: group I (primary radical surgery, n = 16) and group II (multistage surgery; drainage only or ileostomy, followed by elective surgery, n = 5). Patient backgrounds and surgical outcomes were compared between the two groups. The term of prenatal diagnosis, preoperative white blood cell count, and preoperative catecholamine use were not significantly different between the two groups. Group I included more mature neonates than group II (gestational age at birth, 35w1d vs 30w1d, p = 0.02; birth weight, 2.5 kg vs 1.1 kg, p < 0.01). Preoperative C-reactive protein was significantly lower in group I (0.37 mg/dL vs 2.8 mg/dL, p < 0.05). Operation time, blood loss, time to enteral feeding, and complication rates were not significantly different between the two groups. The surgical outcomes of primary radical surgery were comparable to those of multistage surgery, although the patients’ backgrounds were different. Our strategy of selecting one-stage or multiple-stage surgery for treatment of meconium peritonitis, depending on the patient’s general condition and degree of intestinal ischemia, was reasonable.

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: 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.

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.

Massive splenomegaly and hypersplenism in patients with biliary atresia after Kasai portoenterostomy were treated with partial splenic embolization or total splenectomy. We performed partial splenectomy to reduce the complications of partial splenic embolization and avoid overwhelming post-splenectomy infection. This study aimed to evaluate the long-term effects of partial splenectomy for hypersplenism on postoperative liver and spleen function in patients with biliary atresia. Among jaundice-free patients with biliary atresia who underwent Kasai portoenterostomy between January 1992 and December 2012, 15 underwent partial splenectomy for massive splenomegaly and hypersplenism at our institution. Changes in the laboratory data 10 years post partial splenectomy were retrospectively investigated, and these along with the latest data were measured. A total of four patients (27%) required living-donor liver transplantation after partial splenectomy, a proportion similar to those who did not undergo partial splenectomy. Compared to the preoperative baseline, the platelet counts were significantly higher at 1 and 3 years after surgery (p < 0.05). Aspartic aminotransferase-to-platelet ratio index was significantly lower at 1, 7, and 10 years after partial splenectomy (p < 0.05). No further surgeries were required for hypersplenism after partial splenectomy over 10 years, and there were no cases of overwhelming post-splenectomy infection after partial splenectomy. Partial splenectomy is safe and effective for the treatment of hypersplenism with biliary atresia over a long time period. It could be considered as an alternative to partial splenic embolization as it can suppress hypersplenism for a long time and induces fewer postoperative complications.

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: 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.
