Abstract:
Objective To discuss the application of cystic cavity flushing technique in percutaneous ethanol sclerotherapy for the thyroid colloid cysts.Methods A total of 49 patients with thyroid colloid cysts were randomly divided into the study group (n=33) and the control group (n=16).Patients in the study group received cystic cavity flushing treatment by using saline together with α-chymotrypsin,which was followed by percutaneous ethanol injection (PEI).Patients in the control group underwent simple aspiration of cyst fluid followed by PEI.The residual cystic volume,the effective rate and the untoward effects were calculated at one,3 and 6 months after the treatment,and the results were compared between the two groups.Results Striking difference in the changes of postoperative residual cystic volume existed between the study group and the control group.The effective rate of PEI in the study group was 93.9％,which was obviously better than 68.8％ in the control group,the difference between the two groups was statistically significant (P＜0.05).No untoward effect was observed during the performance of aspiration of cyst fluid and flushing of cystic cavity.Nevertheless,bad side effect occurred in PEI procedure in both the study group (6.1％) and the control group (8.3％),but the difference was not statistically significant (P=0.75).Conclusion For the treatment of thyroid colloid cysts,the use of aspiration of cyst fluid together with cystic cavity flushing technique by using saline combined with α-chymotrypsin is safe and reliable,it can improve the curative effect of subsequent PEI.
