Article Synopsis
- The study investigates pain levels in children under 5 years undergoing inguinal hernia repair using either laparoscopic approach (LA) or traditional open approach (OA).
- A total of 74 patients' records were reviewed, and pain was assessed using the FLACC scoring system, which rates pain based on facial expressions, leg movement, activity, crying, and consolability.
- Results showed that while LA is less invasive, it did not result in lower postoperative pain levels compared to OA, particularly in children younger than 2 years.
Background: Recent studies have reported the high incidence of undescended testis (UDT) in patients with gastroschisis. Although various mechanical, hormonal, and genetic theories have been postulated to describe testicular descent, the mechanism contributing to this condition remains controversial. We aimed to investigate the incidence and risk factors of UDT in infants with gastroschisis.

Therefore, we aimed to investigate if computed tomography CT-guided marking is a feasible and safe method for the identification and resection of tiny pulmonary lesions in pediatric cancer patients.
Methods: We retrospectively reviewed the medical records of pediatric cancer patients who underwent CT-guided marking procedures in our institutions between Jan 2011 and Apr 2020.
This is the first report of an immature sacrococcygeal teratoma with inguinal lymph node metastasis, providing the histologic transformation of an immature teratoma in association with chemotherapy. Incomplete tumor resection with coccygectomy was performed, and the histopathologic diagnosis was a grade 3 immature teratoma. Following the initial surgery, the residual tumors enlarged and the tumors metastasized to the inguinal lymph node, demonstrating immature teratoma without yolk sac tumor components.

Methods: Twenty-nine patients with a minimum of 3 years of follow-up who underwent resection and were histologically diagnosed with SCTs between 1982 and 2017 at our institution were included.
Results: The median age at the time of the study was 10.
