Combined use of early enteral nutrition, growth hormone and fibrin glue improves healing of intestinal anastomosis in intra-abdominal sepsis rats / 肠外与肠内营养

ABSTRACT

Objective: To investigate the effects of combined use of early enteral nutrition, growth hormone and fibrin glue on early healing of intestinal anastomosis in intra-abdominal sepsis rats. Methods: Male Wistar rats were randomized into 3 groups. In Control group, antimesenteric transverse enterotomy of 4mm was performed, a second laparotomy was subsequently performed after 24 hours, 6cm of the intestine in the middle of the fistula segment was resected. An end-to-end single layer anastomosis was constructed using 8 interrupted 6-0 polypropylene sutures; In EN group, anastomosis was constructed using 4 interrupted sutures and sprayed fibrin glue, enteral nutrition was given on the second postoperative day for 12 days; In EN/GH group, the animals were treated as EN group, and growth hormone(3.0 U/kg/d) was injected subcutaneously every 24 hours for 14 days. The anastomotic bursting pressure and breaking strength, hydroxyproline content and histology were measured as indicators of wound healing. Results: Anastomotic bursting pressure, anastomotic breaking strength and hydroxyproline content in EN+GH group were higher than that in control and EN groups. Conclusions: Combined use of early enteral nutrition , growth hormone and fibrin glue improves early healing of intestinal anastomosis in intra-abdominal sepsis rats.
