Effect of the cisplatin applied before and after the surgical procedure on the healing of colonic anastomoses in rats

BACKGROUND: Cisplatin is the first line drug in the treatment of the ovarian cancer. This drug is often applied before or after a surgical procedure to whom a large bowel anastomosis is done. OBJECTIVE: Histological evaluation of the effect of the cisplatin on the healing of the colonic anastomoses. METHODS: Eighty male Wistar rats were divided in three groups: the control group, the group that received intraperitoneal cisplatin injection for five days before the surgical procedure and the group that received the cisplatin for five days after the surgical procedure. The cisplatin was used in the dose of 0,35mg/kg. The large bowel was transected 5cm above peritoneal reflection and it was anastomosed in one plan suture. Half of the animals were sacrificed on the fifth day and the other half on the eighth day after the surgical procedure. Histological parameters of inflammatory reaction were evaluated with the elaboration of indexes and scores to compare the groups of this study. RESULTS: The average of neutrophilic infiltrating index was significatively bigger in the group that received cisplatin after the surgical procedure when compared with the control group and the group that received cisplatin before the surgery. The average of intensity of the edema index was significatively bigger in the groups that received cisplatin when compared with the control group. The analysis of the final histological score allowed the classification of the inflammatory process as subacute in the groups that received cisplatin and chronic in the control group. DISCUSSION AND CONCLUSION: Cisplatin produces an impairment on the healing of the colonic anastomoses.
