  • Study of Accelerating Effect of Local Delayed Releasing Vascular Endothelial Growth Factor on Healing of Intestinal Anastomotic Stoma

    Objective To investigate the effect of local delayed releasing vascular endothelial growth factor (VEGF) on accelerating healing of intestinal anastomotic stoma. Methods An intra-abdominal infection modal of rabbit was established by artificial appendix perforation, and excision and anastomosis of terminal ileum were subsequently performed after 12 h. The animals were divided into four groups (32 for each group) with different reagents on anastomotic surface: control group, fibrin glue group (FG group), VEGF group, and VEGF+FG group. The incidence of stomal leak, anastomosic bursting pressure, hydroxyproline content, and expression of VEGF in cured stoma tissue were measured respectively on day 3, 5, 7 and 14 after operation. Results The total incidence rate of leakage was lower in FG group and VEGF group than that in control group, but there was no statistical significance (Pgt;0.05). The incidence rate was significantly lower in FG+VEGF group than that in control group (Plt;0.05). On day 14 postoperatively, the bursting pressure of anastomotic stoma, hydroxyproline content, and positive cell expression rate of VEGF protein (except VEGF group) were significantly increased in FG+VEGF group than those in other three groups (Plt;0.05, Plt;0.01). Conclusion Local delayed release of VEGF by fibrin glue can improve the healing of intestinal anastomotic stoma and reduce the incidence of stomal leak.

  • Randomized Control Study on Seromuscular Layer Anastomosis and Two-Layer Anastomosis in Small Intestinal Suture

    Objective To evaluate the safety and effect of seromuscular layer anastomosis in small intestinal suture. Methods Forty patients with hepatobiliary and pancreatic diseases undergoing biliojejunostomy or cystojejunostomy were randomly divided into seromuscular layer anastomosis group (n=20) and two-layer anastomosis group (n=20) before operation, which received Roux-en-Y end-to-side jejunal seromuscular layer anastomosis and two-layer anastomosis, respectively. Intestinal anastomotic complications and other indexes such as anus venting time were recorded in each group. Results Neither group had intestinal anastomotic complications such as leakage, stricture, obstruction and hemorrhage. Time of venting to normal were (3.6±0.9) d and (3.6±0.8) d in seromuscular layer and two-layer anastomosis group respectively, there was no significant difference between them (Pgt;0.05). Conclusion Seromuscular layer anastomosis is a safe and effective method of small intestinal anastomsis.
