Effects of Rosmarinus officinalis extract on wound healing, colon anastomosis, and postoperative adhesion in colon anastomosis rats.

Background: Intraabdominal adhesions increase the incidence and length of surgical complications. Many anti-adhesive agents have been used for this purpose, but no definitive solution has yet been found. Studies on the prevention and reduction of anastomotic leakage, therefore, remain up to date. This study aimed to determine the effects of Rosmarinus Officinalis extract on colon anastomosis as a surgical model, its antiadhesive activity, and its impact on wound healing in the laparotomy site simultaneously to facilitate the clinical application of Rosmarinus Officinalis extract.

Methods: The rats were divided into two groups of seven rats each. Group C (Control): Laparotomy with colon anastomosis + 2 mL isotonic solution. Group R (Rosmarinus officinalis): Laparotomy + colon anastomosis, + 2 mL of 2% rosmarinus officinalis. Macroscopic adhesion scoring was performed and recorded. The tensile strength of the wound was assessed using tissue samples obtained from the incision line. From the incision line, tissue samples were obtained for histopathological investigation and tissue hydroxyproline levels. Anastomotic burst pressure was measured from the segment of colon anastomosis.

Results: In terms of Macroscopic adhesion score, there was no statistically significant difference between Group C and Group R (p=1.000). The mean Wound tensile strength value of Group R was significantly lower than that of Group C (p=0.003). In terms of mean Anastomotic burst pressure, there was no statistically significant difference between Group C and Group R (p=0.078).

Conclusion: According to the findings of our investigation, peritoneal administration of Rosmarinus Officinalis extract in the early postoperative period may increase the risk of evisceration in the abdominal incision site.
