A novel piglet model of esophageal stricture following variable segmental esophageal resection and re-anastomosis.

Background: Esophageal strictures following esophageal atresia repair are a source of significant morbidity. To test new therapeutic approaches, we designed a piglet model of esophageal stricture by resecting variable lengths of esophagus with subsequent re-anastomosis. This study describes the model and validates its physiologic impact by blinded analysis of the weight gains of the piglets.

Intestinal Anastomosis During Enterostomy Takedown Using a 5 mm Miniature Endostapler Compared to Conventional Handsewn Technique.

Aim: Enterostomy takedown is common in neonates with Hirschsprung's disease, anorectal malformations, or necrotizing enterocolitis. Stapled bowel anastomosis has become routine in adults, but size of up to 12 mm diameter precludes performing enterostomy takedown in young infants using regular intestinal staplers. After the introduction of miniature (5 mm diameter) staplers, we increasingly used them for enterostomy takedown.

Magnets in Paediatric Surgery.

Magnetism, recognized in ancient Greece and China, is a fundamental physical force influencing numerous domains, including medicine and surgery. Historically, the medical use of magnets dates back over two millennia. As proof, the ancient Sanskrit medical textbook Sushruta Samhita describes the removal of a metallic arrow lodged in the flesh with a magnet.
