Purpose: To assess the risk of developing thoracogenic scoliosis (THS) in paediatric patients, depending on the side of lateral thoracotomy (LT) and of spine deviation in the coronal plane by means of logistic regression and scoliosis-free survival analyses.

Methods: A total of 307 consecutive patients undergoing LT were retrospectively reviewed; 32 patients met the inclusion criteria: 1) underwent LT and developed THS; 2) age < 15 years at LT; 3) clinical and radiographic follow-up ≥ 5 years. Patients were divided into ipsilateral group (convexity ipsilateral to LT) and contralateral group (convexity contralateral to LT).

Article Synopsis
  • The study aimed to evaluate the midterm outcomes of lateral thoracotomy in skeletally immature children focusing on the development of thoracogenic scoliosis and the extent of lung tissue resection.
  • A total of 129 children were analyzed, with findings showing that scoliosis typically developed an average of 5.3 years post-surgery, affecting 28.7% of patients, though no significant risk factors were identified for its occurrence related to surgery age or lung resection extent.
  • The findings highlight the need for ongoing monitoring of these patients, as scoliosis can progress years after the initial surgery, even without major spinal deformities noted prior.

Ewing's sarcoma is the second most frequent primary malignant bone tumor in adolescents and young adults. Locations on the thoracic wall represent up to 20% of primary and secondary locations. We present the case of a 13-year-old patient treated with the use of a radiolucency porous bioceramic prosthesis as a sternal replacement for a wide tumor resection in an oncologic context.

Background: Given the high prevalence and complication risks of acid gastroesophageal reflux (GERD) in the first months of life in infants with esophageal atresia, the ESPGHAN/NASPGHAN consensus statement recommends systematic treatment with proton pump inhibitors (PPIs) until the age of 1 year and checking for acid GERD thereafter. However, these recommendations have not been evaluated.

Methods: This prospective study was conducted from 2007 to 2016.

Article Synopsis
  • In pectus excavatum repair, minimally invasive endoscopic techniques are currently preferred for adolescents, but bar displacement remains a significant postoperative concern.
  • A new transcostal technique utilizing absorbable sutures was tested in 36 patients, resulting in only one case of bar displacement (2.78%), which is quite low.
  • This method shows comparable bar stability to existing literature while avoiding complications associated with traditional fixation methods involving metal components.
