Purpose: To assess the impact of the relationship between renal pedicles and tumors on surgical outcomes in patients with non-high-risk abdominal neuroblastoma.
Methods: We retrospectively analyzed cases of neuroblastoma without metastasis treated at our hospital between March 2002 and December 2023. Cases in which surgical resection was performed were divided into three groups according to imaging findings at the time of diagnosis and before surgery: Group E (tumor encasing renal pedicles), Group C (tumor in contact with renal pedicles), and Group S (tumor separated from renal pedicles).
Background Umbilical mucosal polyps are common, but physicians' unfamiliarity with them can prolong the patient's illness. Furthermore, the details of surgery for umbilical mucosal polyp removal are not well documented. Methods Patients with an umbilical mucosal polyp diagnosed on the basis of the lesion's characteristic appearance were prospectively enrolled.

- This study examines the effectiveness and predictors of failure in hydrostatic enema procedures for treating intussusception in children, looking specifically at the use of a water-soluble contrast medium.
- Conducted at the Tokyo Metropolitan Children's Medical Center from March 2010 to May 2022, the research analyzed outcomes from 351 cases where initial attempts were made with the contrast medium positioned at or below 120 cm.
- The findings revealed a 77.5% success rate for reductions at that height, while indicating that younger children (under 12 months) and those with trapped fluid were more likely to experience failed attempts.
Article Synopsis
- This study reviews the treatment of seven children with trisomy 18 who developed hepatoblastoma, highlighting the successful outcomes of multidisciplinary approaches.
- Out of 69 patients, six had hepatoblastoma, with seven undergoing complete surgical resection and supportive treatments like chemotherapy.
- The findings suggest that children with trisomy 18 and stable health conditions can benefit from aggressive treatment strategies, leading to disease-free outcomes in all observed cases post-surgery.
Purpose: Long-gap esophageal atresia (LGEA) is still a challenge for pediatric surgery. No consensus exists as to what constitutes a long gap, and few studies have investigated the maximum gap length safely repairable by primary anastomosis. Based on surgical outcomes at a single institution, we aimed to determine the gap length in LGEA with a high risk of complications.
