Mesenteric Neovascularization during Spring-Mediated Intestinal Lengthening

Porcine study demonstrates that spring-mediated intestinal lengthening induces significant mesenteric neovascularization, with 2.5-fold increase in macroscopic vessels and doubled density of microscopic arterioles and venules. Findings support distraction enterogenesis as a viable treatment approach for short gut syndrome by showing the mesentery's capacity to recruit blood supply during intestinal growth.
