Experience in the diagnosis and treatment of breast lesions with ultrasound-guided Mammotome biopsy

Objective To summary the experience in the diagnosis and treatment of breast lesions with ultrasound guided Mammotome biopsy.Methods The data of 63 patients who underwent an ultrasound-guided minimally invasive excisional breast biopsy were collected from November 2002 to November 2005 and the indications,procedures and complications of Mammotome-biopsy were also analyzed.Results There were 93 lesions in 63 patients who presented with breast lesions.All the 93 lesions were excised.The size of the lesions was ranged from 0.5cm to 2.5cm..The average time for excision of each lesion was 22 minutes(range from 10min to 55min).The complete removal of lesions was demonstrated by ultrasonography.In all but one case with hematoma in the breast and two cases with bruise,no other complications were found.Four patients were diagnosed malignant lesions(3 invasive duct carcinomas and one DCIS),the remainder had benign pathology including one intraductal papilloma,5 fibroadenomas,53 fibrocystic hyperplasias or adenosises.The patients were followed up after Mammotome biopsy by physical examination and ultrasonography,no lumps were found.Conclusions The ultrasound guided Mammotome-biopsy is a minimally invasive,safe and accurate technique for diagnosing of breast lesions.In addition,it may be regarded as a therapeutic alternative for small fibroadenomas((2.5cm),)but further clinical study was warranted.
