THE EFFECTS OF STANOZOLOL AND HIGH PROTEIN DIET ON COLON ANASTOMOSIS

Background: Anastomotic leakage after colonic resection and anastomosis are serious complications with high morbidity and mortality. Collagen synthesis is an essential feature of anastomotic healing. Objective: Our study aimed to investigate individual and combined effects of high protein diet and stanozolol on the intestinal anastomosis in rats. Methods: Total of 48 Wistar-albino rats were divided into four groups. Group C: Control group; Group P: high protein diet (4mg/day) administered by gavage; Group A: group to which stanozolol was administered intramuscularly (i.m) (2mg/kg/day); Group A+P: group to which both stanozolol (2mg/kg/day) i.m and high protein diet (4mg/day by gavage) were administered. In each group, half of the animals underwent surgery on the 3 rd postoperative (PO) day and the other half on the 7 th PO day for analysis procedures. Bursting pressures of each anastomotic segment, tissue hydroxyproline levels, and histologic tissue repair process were evaluated. Results: On 7 th PO day, group A+P had statistically and significantly higher bursting pressures than the control group. Hydroxyproline levels at the anastomotic segment on both 3 rd and 7 th PO days were also significantly higher in group A+P. Conclusion: A high protein diet and stanozolol do not significantly impact the anastomotic healing when used separately. We concluded that high protein diet and stanozolol can be used after colorectal surgery in humans but requires further research.
