Impact of remote ischemic preconditioning on wound healing in small bowel anastomoses

Figure 1 Bursting pressure after different remote ischemic preconditioning settings and after arginine application expressed as box plot. There was no significant overall difference between the groups (P > 0.05). RIPC: Remote ischemic preconditioning.

Figure 2 The histological mucosal damage score by Chiu[23] showed significantly more low-grade alterations in the remote ischemic preconditioning groups (Remote ischemic preconditioning, 27% vs control, 10%). RIPC: Remote ischemic preconditioning.

Figure 3 Histological view. A: Chiu grade 0 with intact epithelium and a few villi along one side of the anastomosis (HE staining; magnification 5 ×), Region of the anastomosis (arrow) and staining artefacts (*); B: Chiu grade 2 with a pronounced subepithelial space in the villi next to the inverted anastomosis (arrow) and a suture hole (*) (HE staining; magnification 5 ×).
