Objective: We aimed to investigate Hypericum Perforatum (St. John's Wort Oil) and pure olive oil with respect to their effect on preventing intra-abdominal adhesions after abdominal surgery.Methods: This was an animal study carried out by the Giresun Faculty of Medicine, Department of General Surgery between August 10, 2020, and September 10, 2020. In the study, intra-abdominal adhesion development was examined macroscopically and microscopically on the 14th day after experimental abdominal surgery in three groups [(i) Control, (ii) olive oil application, (iii) St. John's Wort oil application] each consisting of 7 female Wistar Albino rats. Majuzi classification and Zuhlke's microscopic adhesion classification was used to evaluate adhesions.Results: Macroscopically, fibrous bands were not observed in 1 rat in the control group, 2 rats in olive oil recipients, and 1 rat in St. John's Wort oil recipients. A significant difference between the groups was identified in terms of Zuhlke's microscopic adhesion scores (p = 0.026). Accordingly, the adhesion level was significantly reduced in olive oil recipients compared to controls (p = 0.002). There was no significant difference in terms of adhesion between all groups (p>0.05). The Majuzi adhesion classifications in the control group, olive oil group and St. John's wort groups were also similar (p = 0.308).Conclusion: In rats who underwent abdominal surgery, it was determined that intra-abdominal olive oil application reduced the level of adhesion, while St. John's Wort oil application had no effect on adhesion formation. |
