Methods: We reviewed the medical files of patients treated for CDE through thoracoscopy from 2000 to 2011. Age at surgery, sex, side of the lesion, procedure's details, postoperative course, and complications were analyzed.

Congenital diaphragmatic hernia: an evaluation of risk factors for failure of thoracoscopic primary repair in neonates.

Purpose: Publications aiming to prove the feasibility and safety of thoracoscopic CDH-repair in neonates grow in numbers. Some teams use selection criteria, but none have proven statistical evidence. The aim of this study is to detect risk factors for failure of thoracoscopic primary closure of CDH in neonates.

Observational, medical or surgical management of vesicoureteric reflux.

Unlabelled: The clinical management of vesicoureteric reflux includes observational, medical and surgical procedures. The choice of management is often a joint decision made between the paediatric nephrologist and urologist. The use of prophylactic antibiotics has become increasingly debated.

Lower pole vessels in children with pelviureteric junction obstruction: laparoscopic vascular hitch or dismembered pyeloplasty?

Objective: To choose between laparoscopic "vascular hitch" (VH) and dismembered pyeloplasty (DP) in treatment of aberrant lower pole crossing vessels potentially responsible for pelviureteric junction obstruction (PUJO) in older children.

Patients And Methods: Retrospective study of 19 patients treated laparoscopically for PUJO. Based on videos of the procedures, we studied the anatomical relationship between the renal pelvis, the pelviureteric junction, and the aberrant vessels.

[Simulation in pediatric surgery].

Simulation in paediatric surgery is essential for educational, ethical, medicolegal and economic reasons, and is particularly important for rare procedures. There are three different levels of simulation:--simulation of basic techniques in order to learn or improve surgical skills (dissection, intracorporeal knots, etc.);--preparation for surgery using virtual reality, to perfect and test various procedures on a virtual patient, and to determine the best approaches for individual cases;--behavioral simulation underlines the importance of the preoperative check-list and facilitates crisis management (complications, conversion, etc.

Button cystostomy for bladder drainage: which children can benefit from this device?

Materials And Methods: We analyzed several criteria of the follow-up of all the patients who had a button cystostomy since 2007 including indications, age, urodynamic variables, and complications.

[Liver torsion leading to death in a 16-month-old infant treated neonatally for an omphalocele].

We report the case of an infant who underwent surgery on the first day of life for a giant omphalocele. At the age of 16 months, he presented an acute abdominal syndrome and died a few hours later. Autopsy revealed a twisted left liver lobe (LL) including a suprahepatic vein.

Pectus excavatum repair according to Nuss: is it safe to place a retrosternal bar by a transpleural approach, under thoracoscopic vision?

We present a new case of cardiac perforation during retrosternal dissection beginning a Nuss procedure for pectus excavatum repair in an 18-year-old boy. The true incidence of life-threatening complications, such as heart injuries during Nuss bar placement for pectus excavatum repair, as well as cardiac lacerations during removal of the bar, remains unknown. Many papers suggest measures to prevent these complications: approaching the retrosternal space through an additional subxiphoid short incision, lifting the sternum during bar placement, or placing the bar extrapleuraly.
