An experimental study on magnetic esophageal compression anastomosis in piglets.

Introduction: Fashioning a patent, watertight anastomosis in patients with esophageal atresia is a challenging task in pediatric surgery, particularly when performed under tension. A reproducible suture-less alternative would decrease operative time. We evaluated magnetic esophageal compression anastomoses in a novel bypass-loop swine model.

Esophageal Blood Flow May Not Be Directly Influenced by Anastomotic Tension: An Exploratory Laser Doppler Study in Swine.

Background:  Anastomotic tension has been linked to leakage and stenosis in esophageal surgery in both adults and children. We aimed to determine the effects of esophageal topography, operative technique, and anastomotic tension on esophageal blood flow.

Materials And Methods:  We divided and reanastomosed the esophagi at the carinal level with increasing levels of anastomotic tension in piglets ( = 10) and sham controls ( = 4).
