An Experimental Study of Intraluminal Hyperpressure Reproducing a Gastric Leak Following a Sleeve Gastrectomy

A gastric leak (GL) represents the main post-operative complication following a sleeve gastrectomy (SG) and occurs most commonly at the top of the stapling, without any clear explanation. This experimental study evaluates the biomechanical behavior of post-SG gastric specimens using both insufflation and tensile tests. A total gastrectomy followed by an ex vivo SG was performed in 15 pigs. The “sleeved” stomachs were subjected to intraluminal...
