The effects of lauromacrogol on thyroid tissue in rabbits. Is this a safe option for the treatment of nodular thyroid disease?
AIM: The effects of lauromacrogol as a sclerosing agent were evaluated on rabbit thyroid tissue.
MATERIAL AND METHODS: Twelve rabbits were divided into two equal groups. Intra-thyroid injections of 0.1 ml lauromacrogol were administered in the study group and 0.1 ml physiologic serum in the control group. The blood levels of free T3, free T4, TSH, postoperative adhesions and histopathologic differences of the thyroid tissues were evaluated.
RESULTS: The values of serum free T3, free T4 and TSH levels did not differ significantly (p>0.05), but the free T3 levels were significantly different in the inter-group analysis (p=0.020). Postoperative macroscopic adhesion scores did not differ significantly (p>0.05). In the histopathologic evaluation, the inflammation and fibrosis scores were significantly higher in the study group (p=0.003).
DISCUSSION: In our study, we found two important outcomes. Firstly, tests of thyroid function were not significantly different between the control and study groups. This important finding suggests lauromacrogol can be safely used without the risk of hypothyroidism or hyperthyroidism. Secondly, the Erlich-Hunt Model histopathologic evaluation results revealed that inflammation and fibrosis were significantly increased in the study group. This finding shows lauromacrogol can be effectively used to treat thyroid nodules by means of fibrosis.
CONCLUSIONS: Lauromacrogol causes fibrosis in thyroid tissue without significant perithyroidal adhesion formation and functional differences. Treatment of nodular thyroid disease with lauromacrogol may be safe.
