Laparoscopic colonic anastomosis using a degradable stent in a porcine model

Figure 5 Masson’s trichrome staining of anastomosis. A, B: Masson’s trichrome staining of the stent group at 2 wk postoperatively (× 100, × 200); C, D: Masson’s trichrome staining of the control group at 2 wk postoperatively (× 100, × 200); E, F: Masson’s trichrome staining of the stent group at 3 mo postoperatively (× 100, × 200); G, H: Masson’s trichrome staining of the control group at 3 mo postoperatively (× 100, × 200). The hyperplastic fibrous tissue and collagenous fibers are shown with green or blue, while hyperplastic smooth muscle cells with red.
