Abstract

Abstract:

Objective

To investigate the application value of light-emitting filament in the treatment of pathologic nipple discharge.

Methods

From May 2009 to October 2012, 32 cases of nipple discharge were randomly divided into improved surgery group (14 cases; light-emitting filaments were inserted into the mammary duct through discharge hole) and conventional surgery group (18 cases; high concentration of methylene blue was used for staining in duct). The data on surgical field contamination,identified small lesions and postoperative pathologic results were analyzed with student’s t test.

Results

Eight patients were observed with methylene blue contaminated field in conventional surgery group(44.4%,8/18), none with surgical field contamination in improved surgery group and the difference was statistically significant(P = 0.004). The operative time was (38±9) min in conventional surgery group,(29±10) min in improved surgery group and the difference was statistically significant(t=2.674,P=0.012). The duct lesions were resected in 32 cases of nipple discharge. All patients were pathologically confirmed, and no complications occurred.

Conclusion

The light-emitting filament can accurately detect the duct lesions and visualize the surgical field so as to bring the convenience and reduce the operative time,which shows good application value in the patients with nipple discharge.
