Abstract

Purpose

Intra-abdominal adhesions (IAA) are among the most frequently seen pathologies in general surgery practice with an increased morbidity and mortality. In the present study, we investigated the effect of locally applied mesenchymal stem cells (MSCs) on IAA.

Methods

Twenty-four Wistar Albino rats were used in the study. The rats were divided into three groups including: Sham, control, and MSCs group. On day 0, cecum was reached under anesthesia in all groups, except the Sham group. Scraping with a sponge was performed until petechial bleeding occurred. The control group received no treatment. In the stem cell group, MSCs were applied topically immediately after surgery on adhesions. The rats were sacrificed on day 10 and colon tissues and blood samples were collected for macroscopic, histopathological, and biochemical analysis.

Results

In our study, E-selectin, P-selectin, TNF-α and IL-1 levels were statistically significantly lower in the MSC group than the control group, while the sham group has the lowest levels. In both the macroscopic and histopathological analyses (Zühlke's scale), the least amount of adhesion was observed in the Sham group. In addition, although there was less adhesion in the MSC group than the control group, the difference did not reach statistical significance.

Conclusion

Topical MSC application immediately after surgery suppresses the inflammatory process. However it was found to be ineffective in histopathological and macroscopic examinations performed on the 10th day.
