Circumferential Esophageal Reconstruction Using a Tissue-engineered Decellularized Tunica Vaginalis Graft in a Rabbit Model.

Background: Pediatric surgeons have faced esophageal reconstruction challenges for decades owing to a variety of congenital and acquired conditions. This work aimed to introduce a reproducible and efficient approach for creating tissue-engineered esophageal tissue using bone marrow mesenchymal stem cells (BMSCs) cultured in preconditioned mediums seeded on a sheep decellularized tunica vaginalis (DTV) scaffold for partial reconstruction of a rabbit's esophagus.

Methods: DTV was performed using SDS and Triton X-100 solutions.

Laparoscopic Suture versus Mesh Rectopexy for the Treatment of Persistent Complete Rectal Prolapse in Children: A Comparative Randomized Study.

Purpose: To compare laparoscopic mesh rectopexy with laparoscopic suture rectopexy. . The prospective study was conducted at Pediatric Surgery Department, Al-Azhar University Hospitals, Cairo, Egypt between Feb 2010 and Jan 2015.

Laparoscopic management of recurrent inguinal hernia in childhood.

Background: Open repair of recurrent inguinal hernias [RIH] in infancy and childhood is difficult and there is definite risk of damaging the vas deferens and testicular vessels. Laparoscopic repair of RIH has the benefit of avoiding the previous operative site. The aim of this study is to present our experience with laparoscopic repair of RIH either after open or laparoscopic hernia repair with stress on technical refinements to prevent recurrence.
