Specific Findings of Blood Perfusion on Anastomosed Esophagus of Neonatal Esophageal Atresia and Tracheoesophageal Fistula Using Indocyanine Green Fluorescence During Thoracoscopic Surgery.

We herein report a neonatal case showing specific findings of blood perfusion in the anastomosed esophagus of esophageal atresia (EA) and tracheoesophageal fistula (TEF) using indocyanine green (ICG) fluorescence during thoracoscopic surgery. The patient was a 3054 g, 0-day neonatal boy diagnosed with EA-TEF based on a coil-up sign of the nasogastric tube. Thoracoscopic surgery was performed on Day 4 after birth.

Favorable inhibitory effect of clodronate on hepatic steatosis in short bowel syndrome model rats.

Purpose: This study investigated the anti-inflammatory effect of clodronate, a vesicular nucleotide transporter (VNUT) inhibitor, on intestinal-failure-associated liver disease (IFALD) in a rat model of short bowel syndrome (SBS).

Methods: The rats underwent jugular vein catheterization for continuous total parenteral nutrition (TPN) and 90% small bowel resection. The animals were divided into the following groups: TPN/SBS (Control group), TPN/SBS/intravenous administration of low-dose clodronate (20 mg/kg twice per week; Low group), or TPN/SBS/intravenous administration of high-dose clodronate (60 mg/kg twice per week; High group).

A Case of an Extremely Preterm Infant with Intussusception Triggered by Acquired Cytomegalovirus Infection.

Intussusception is a common cause of intestinal obstruction in infants aged 6-18 months. However, intussusception in preterm neonates (IPN) is an exceedingly rare disorder. The etiology of IPN remains unclear, but common prenatal injuries, such as those causing intestinal hypoxia/hypoperfusion, dysmotility, and strictures, have been proposed as possible contributing factors.

Endosurgery workshop to improve the confidence of novice pediatric surgeons in performing laparoscopic hepaticojejunostomy.

Purpose: This study assessed the efficacy of a high-impact, short-term workshop in honing the laparoscopic hepaticojejunostomy technical skills and self-confidence of novice pediatric surgeons, focusing on vertical needle driving and knot tying.

Methods: Lectures, hands-on sessions, pre- and post-workshop evaluations, and training using porcine models were conducted to refine basic and advanced skills. The "hepaticojejunostomy simulator" was used for comparative analysis of precision in pre- and post-workshop vertical needle driving and knot tying.

Contrast-enhanced ultrasound findings in testicular torsion and non-testicular torsion.

Purpose: Testicular torsion requires emergency surgery; thus, prompt and correct diagnosis is very important. Ultrasound with color Doppler is usually the first-choice modality for diagnosis; however, skill and experience are required for confident diagnosis. Recently, contrast-enhanced ultrasound for the diagnosis of testicular torsion has been reported, but there have been only a few reports.

Infantile type I pleuropulmonary blastoma presenting with dyspnea due to compression by pneumothorax and an occupying tumor: a case report.

Background: Pleuropulmonary blastoma (PPB) is an extremely rare and malignant pediatric lung tumor. Purely cystic PPB has a more favorable prognosis than solid PPB, but may be difficult to distinguish from a certain type of "benign" congenital pulmonary airway malformation before and during surgery. The influence of tumor rupture on long life prognosis has not been clarified in detail.

Contrast-enhanced ultrasonographic findings in torsion of the appendix testis or epididymis in children: a case series.

Purpose: Torsion of the appendix testis or epididymis is a cause of acute scrotum in children. Ultrasonography with color Doppler is the first-choice modality for diagnosis. However, this method requires skill and experience to make a diagnosis with confidence.

Challenging management of a baby with congenital multiple intestinal atresia, trisomy 18 and extremely low birth weight: a case report.

Background: Extremely low birth weight (< 1000 g) still influences postsurgical prognosis in the neonatal and infantile periods. Additionally, the life expectancy of neonates with trisomy 18 is extremely poor owing to various comorbidities. Therefore, it takes courage to perform laparotomy for the purpose of treatment of congenital multiple intestinal atresia in a baby with an unpredictable life prognosis.

Axillary skin crease incision versus conventional posterolateral incision in open repair of patent ductus arteriosus for extremely low birth weight infants: a retrospective study.

Background: Thoracotomy with posterolateral incision (PLI) is commonly used for surgical repair of patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. Some reports have described thoracotomy for PDA using an axillary skin crease incision (ASCI) in consideration of cosmetic problems such as surgical wounds and thoracic deformities, but the details remain unclear.

Methods: In this study, we performed clipping ligation by thoracotomy with ASCI for ELBW infants with PDA from 2011 to 2015 for the purpose of improving cosmetic results, and retrospectively compared the results with those for conventional PLI cases performed from 2016 to 2020.

Neonatal necrotizing fasciitis with gas gangrene due to peripherally inserted central catheter-related infection.

Background: Necrotizing fasciitis in neonates is a rare and life-threatening infection involving necrosis of the skin, subcutaneous tissues, deep fascia, and sometimes underlying muscles, with a fulminant course and high mortality rate. Necrotizing fasciitis with gas gangrene related to infection of a peripherally inserted central catheter is very rare.

Case Presentation: The patient was a full-term female neonate born by vaginal delivery.

Median sternotomy approach for the repair of esophageal atresia: a case report.

Background: Repair of esophageal atresia is usually performed through the right thoracic cavity. However, when the upper pouch of the esophagus and tracheoesophageal fistula (TEF) is located in the thoracic inlet and completely on the left side of trachea, it is difficult to dissect and anastomose the esophagus through the right thoracic cavity. We present a case of esophageal atresia, with the esophageal upper pouch located high and completely on the left side of trachea, successfully repaired via the median sternotomy approach.
