To study the postoperative recurrence of intraductal papillomas (IDP) treated with ultrasound-guided vacuum-assisted excision (VAE), and to investigate the effect of different lesion characteristics on recurrence.

106 patients with IDP with or without atypical ductal hyperplasia (ADH) treated with ultrasound-guided VAE at Zhongnan Hospital of Wuhan University from January 2020 to August 2024 were selected for the study, and the postoperative conditions of the patients were sorted out and followed up to analyze the characteristics of the lesions and to determine the relevant factors that affected the postoperative recurrence.

Inclusion Criteria:

• IDP was diagnosed pathologically after VAE treatment
• the tumor was a solitary lesion with the margin >1cm from the nipple and the longest diameter of the tumor <3cm
• it was not associated with other breast diseases

Exclusion Criteria:

• previous ductal breast surgery
• abnormal coagulation function or taking anticoagulant drugs .recent or current use of hormonal or psychotropic drugs.

IDP patients who underwent ultrasound-guided VAE treatment from January 2020 to August 2024 in Zhongnan Hospital of Wu han University.

all collected IPD, all IPD that underlie results in a publication

starting 6 months after publication

The IPD can be shared for the summary report of test results,the reanalysis of test data and enables the combination of test data with other data for new research.
