Purpose: Gastrointestinal bleeding (GIB) due to esophageal varices (EV) is one of the factors that negatively impact native liver survival of patients with biliary atresia (BA). Gastrointestinal fibroscopy (GIF) is usually used to determine the presence of EVs; however, it requires general anesthesia. The aim of this study is to search for markers in blood tests obtained during routine check-ups that can predict the development of GIB. Methods: Data of patients with BA who underwent portoenterostomy at our hospital from 2014 to 2020 were retrospectively reviewed. The patients’ data were assigned to three groups according to specific time points: Group B, which included data at GIB; Group NB-T, which included data at GIF and EV treatment; and Group NB-NT, which included data at GIF without treatment. The data in Group B were compared to those of other groups. Results: In our study, GIB occurred in 11 patients, and 12 cases and 8 cases were classified into Groups NB-NT and NB-T, respectively. Compared with the other groups, only ChE and M2BPGi in Group B showed statistically significant differences. Conclusions: ChE and M2BPGi are useful for predicting GIB.

Background: Omphalocele is a congenital abdominal wall defect of the umbilical cord insertion site. A giant omphalocele, with a fascial defect > 5 cm in diameter and/or containing > 50% of the liver within the hernia sac, can be challenging for pediatric surgeons. Recently, negative pressure wound therapy has been reported as an effective management for giant omphaloceles; however, it is not recommended for an infected wound with necrotic tissue as it may exacerbate infection. We adopted negative pressure wound therapy with irrigation and dwell time (NPWTi-d) for a case of a ruptured giant omphalocele. Artificial membranes, followed by artificial dermis, were used to promote fibrous capsule formation, and then NPWTi-d was used to promote granulation while controlling infection. However, studies have not been conducted regarding NPWTi-d for ruptured giant omphaloceles; hence, we present our treatment experience with NPWTi-d for a giant omphalocele. Case presentation: The patient was a boy born at 38 weeks and 3 days of gestation, weighing 1896 g. He was diagnosed with a ruptured giant omphalocele with a total liver and intestine defect hole of 10 cm × 10 cm. The patient underwent silo placement using an artificial mesh, followed by plicating the artificial mesh at 4 days of age. The herniated viscera were gradually reduced into the abdominal cavity; however, the defect size was still large. Hence, a collagen-based artificial dermis was patched on the defect hole. After creating a fresh and smooth granulated tissue, NPWTi-d was applied at 33 days of age to promote granulation and control infection. We used the 3 M™ V.A.C.® Ulta Therapy Unit with 3 M™ VeraFlo™ therapy. NPWTi-d was stopped at 60 days of age when the granulation tissue was well formed including at the artificial dermis site. The wound was managed with prostandin ointment and appropriate debridement, resulting in complete epithelialization at 5 months of age. Conclusions: Artificial membranes followed by artificial dermis were used to promote a fibrous capsule and artificial dermis granulation, which protects against organ damage. NPWTi-d achieved better control of infection and promoted wound healing. NPWTi-d combined with artificial dermis can effectively treat ruptured giant omphaloceles.

Hernioplasty for giant inguinal hernias can cause abdominal compartment syndrome (ACS) in adults but rarely does in infants. We encountered a case of a giant bilateral inguinal hernia in infancy complicated by ACS after hernioplasty. Silo placement via a skin incision effectively treated ACS, after which the abdominal wall was safely closed. Hernioplasty performed early in the clinical course can help expand the abdominal cavity and avoid ACS. Thus, hernioplasty should be performed earlier if the hernia size in the flank space gradually increases.

Background: The prognosis of BA is known to be poor if definitive surgery is performed too late. Therefore, excluding BA as a diagnosis at an early stage is crucial. Conventional cholangiography requiring cannulation through the gallbladder may be unnecessarily invasive for patients, especially when ruling out BA. Therefore, a less invasive alternative such as indocyanine green (ICG) cholangiography, which does not require cannulation, should be established. In this study, we focused on excluding BA and confirmed the usefulness of intravenous ICG fluorescence cholangiography. To the best of our knowledge, this is the first preliminary study to report the use of intravenous ICG cholangiography for BA exclusion. Methods: The study participants were patients who underwent liver biopsy and intraoperative cholangiography after they were suspected to have BA, between 2013 and 2022. ICG fluorescence cholangiography was performed on all patients who provided informed consent. Results: During the study period, 88 patients underwent a laparoscopic liver biopsy and cholangiography. Among them, 65 (74%) were diagnosed with BA and underwent a subsequent laparoscopic Kasai portoenterostomy. BA was ruled out intraoperatively in 23 patients. Of the 23 patients in whom BA was ruled out, 14 underwent ICG cholangiography, 11 had gallbladder (GB) fluorescence, and 9 had both GB and common bile duct (CBD) fluorescence. Conventional cholangiography was very difficult in 2 of 23 cases: in 1 case, cannulation of the atrophic gallbladder was impossible, and cholecystectomy was indicated after multiple attempts; in 1 case, upstream cholangiography was not possible. In both cases, ICG fluorescence cholangiography successfully imaged the CBD and the GB. Conclusions: In conclusion, intravenous ICG fluorescence cholangiography might be a useful and less invasive diagnostic procedure that can rule out BA in infants.

This study aimed to evaluate the safety and effectiveness of circumumbilical incision (CUI) for neonates requiring intestinal anastomosis. Seventy neonates requiring intestinal anastomosis at our institution between 2003 and 2020 were included in this retrospective case-control study. Patients were classified into the CUI (25 patients: 36%) and transverse incision (TI) groups (45 patients: 64%). Postoperative complications and surgical outcomes were compared between the two groups. Intestinal perforation at the non-anastomotic site occurred significantly more often in the CUI group than in the TI group (3 patients: 12%, and 0 patients: 0%, respectively (p = 0.042)). There were no between-group differences regarding anastomotic leakages, anastomotic strictures, time to enteral feeding, operative time, and blood loss. Neonatal intestinal surgery employing CUI might be associated with increased intestinal perforation at the non-anastomotic site. Hesitating to enlarge the skin incision to maintain favorable cosmetic outcomes might cause severe injury to the delicate neonatal intestine during the surgical procedure owing to the restricted surgical field. When performing CUI, we suggest that the skin incision should be extended without hesitation whenever there is difficulty in manipulating the intestine.

Background: After surgery for congenital biliary dilatation (CBD), hilar and hepatic bile duct stenosis and intrapancreatic bile duct remnants can cause many postoperative complications. We investigated the efficacy of laparoscopic surgery with aggressive bile ductoplasty and complete excision of the intrapancreatic bile duct in CBD patients compared to open surgery. Methods: Pediatric patients who underwent surgery for CBD at our institution between 2006 and 2020 were divided into two groups: laparoscopic surgery (Lap group) and open surgery (Op group). Surgical outcomes were compared between the two groups. Results: We enrolled 160 patients (85 in the Lap group and 75 in the Op group). Hilar bile ductoplasty was performed in 52 (61%) patients from the Lap group and 40 (53%) patients from the Op group. The operative time was significantly longer, the amount of blood loss was significantly lower, and the length of hospital stay was significantly shorter in the Lap group than in the Op group. Postoperative early and late complications occurred at a similarly low rate in both groups. When the surgical outcomes were compared between the group who underwent laparoscopic bile ductoplasty and the group that did not, postoperative early and late complications occurred similarly in both groups. Conclusions: Laparoscopic surgery for CBD with aggressive hilar bile ductoplasty and complete excision of the intrapancreatic bile duct is safe and effective, comparable to open surgery. However, it is necessary to verify whether long-term occurrence of hepatolithiasis similar to open definitive surgery can be obtained in the future.

Background: Pediatric surgeons require highly advanced minimally invasive surgical skills to perform rare and complex surgeries in a very vulnerable population. We developed a neonatal esophageal atresia (EA) model to improve thoracoscopic surgical skills. This study aimed to evaluate the concurrent validity of the model by undertaking pre- and post-training skills assessments in two groups of students with no prior experience performing minimally invasive surgery, using the EA model and a dry box (DB). Methods: A pilot study was performed. The participants were randomly divided into two groups: one trained using the DB and one trained using the EA model. Both groups practiced a minimally invasive surgical suture task. The task completion time, 29-point checklist score, modified suturing error sheet score, and three-dimensional forceps movement in both groups were compared pre-and post-training by video analysis. Results: The EA model task was significantly more difficult than that of the DB. Both groups showed significant improvement in the task time, 29-point checklist score, and modified suturing error sheet score; however, the EA model training was more efficient in improving each error item. Regarding forceps movement, the EA model training significantly decreased wasted motion, whereas the DB was limited in this regard. Conclusions: Short-term training on the EA model, which was more technically demanding than the DB, decreased technical error and wasted motion, and allowed learners to acquire surgical skills more efficiently than training with the DB model. These facts revealed the concurrent validity of the EA model.

Central venous catheters (CVCs) are essential devices in the treatment of pediatric patients with hematological and oncological disorders; however, the most suitable type of CVC for these patients remains unclear. We retrospectively compared risk factors for unplanned removal of two commonly used CVCs, peripherally inserted central catheters (PICCs) and tunneled CVCs, to propose which is the better device. We followed 89 patients fitted with a tunneled CVC (total 21,395 catheter-days) and 84 fitted with a PICC (total 9177 catheter-days) between January 1, 2013 and December 31, 2015, until catheter removal. Patients with a PICC had a significantly higher 3-month cumulative incidence of catheter occlusion (5.2% vs. 0%, p = 4.08 × 10<sup>−3</sup>) and total unplanned removals (29.0% vs. 6.9%, p = 0.0316) than those with tunneled CVCs. However, the cumulative incidence of central line-associated bloodstream infection did not differ significantly by CVC type. Multivariable analysis identified younger age (< 2 years) [sub-distribution hazard ratio (SHR) 2.29; 95% confidence interval (CI) 1.27–4.14] and PICC (SHR 2.73; 95% CI 1.48–5.02) as independent risk factors for unplanned removal. Thus, our results suggest that tunneled CVCs are preferable in pediatric patients with hematological and oncological disorders requiring long-term, intensive treatment.

Background: Esophageal atresia (EA) is often associated with tracheomalacia (TM). The severity of TM symptoms varies widely, with serious cases requiring prolonged respiratory support and surgical treatment. Although we performed thoracoscopic posterior tracheopexy (TPT) during primary EA repair to prevent or reduce the symptoms of TM, few studies have investigated the safety and effectiveness of TPT during primary EA repair. Therefore, this study aimed to evaluate the safety and efficacy of TPT in neonates. Methods: We retrospectively reviewed the records of all patients diagnosed with TM who underwent primary thoracoscopic EA repair between 2013 and 2020 at the Nagoya University Hospital. Patients were divided into two groups: TPT (TPT group) and without TPT (control group). TPT has been performed in all patients with EA complicated by TM since 2020. We compared patient backgrounds, surgical outcomes, postoperative complications, and treatment efficacy. Results: Of the 22 patients reviewed, eight were in the TPT group and 14 were in the control group. There were no statistically significant differences in the surgical outcomes between the groups (operation time: p = 0.31; blood loss: p = 0.83; time to extubation: p = 0.30; time to start enteral feeding: p = 0.19; time to start oral feeding: p = 0.43). Conversion to open thoracotomy was not performed in any case. The median operative time required for posterior tracheopexy was 10 (8–15) min. There were no statistically significant differences in postoperative complications between the groups (chylothorax: p = 0.36; leakage: p = 1.00; stricture: p = 0.53). The respiratory dependence rate 30 days postoperative (2 [25%] vs. 11 [79%], p = 0.03) and the ratio of the lateral and anterior–posterior diameter of the trachea (LAR) were significantly lower in the TPT group (1.83 [1.66–2.78] vs. 3.59 [1.80–7.70], p = 0.01). Conclusions: TPT during primary EA repair for treatment of TM significantly lowered respiratory dependence rate at 30 days postoperative without increasing the risk of postoperative complications. This study suggested that TPT could improve TM associated with EA.

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.
