Giant umbilical hernia: "Lazy M-Omega" flap, a case report.

Umbilical hernia, one of the most frequent pathologies in pediatric surgical practice, is usually corrected with a relatively simple intervention, except in cases where there is a major defect, also called proboscoid hernia. We present a case report of a 20-month male patient that underwent surgical intervention of a giant umbilical hernia with the "Lazy-M and Omega" flap novel surgical technique. This technique has to be taken into account in surgical planning, since it is simple and easily reproducible.

Three-Dimensional Printed Model and Virtual Reconstruction: An Extra Tool for Pediatric Solid Tumors Surgery.

 Three-dimensional (3D) technology is increasingly applied for planning challenging surgical interventions. We report our experience using 3D printing and virtual reconstruction for surgical planning of complex tumor resections in children.  Data were obtained from preoperative magnetic resonance.
