Evaluation of the results of vacuum aspiration biopsy using the “Encorenspire” device in treatment of patients with benign mammary gland tumors

Abstract

Aim to compare the results of vacuum aspiration biopsy (VAB) and sectoral resection in the treatment of benign breast tumors.
 Material and methods.During the study we compared the results of treatment in two groups of patients. The main group included 50 patients (mean age 54.830.934 years) who underwent VAB, the control group comprised 55 patients (mean age 55.7041.998 years) who underwent sectoral resection. Before the surgery, a tumor biopsy was performed with the following cytological and histological examination. The diagnosis of fibroadenoma was predominant. After the operation, a histological analysis of the received preparations was done. We assessed the immediate postoperative results, such as: blood loss, operation time, intensity of pain syndrome, bed-day number, quality of life after the operation.
 Results.The duration of surgery was significantly lower in patients with VAB than in patients with sectoral resection (p=0.000). The blood loss after surgery did not differ significantly (p=0.921) and did not exceed 10 ml in both groups. The groups under study were comparable according to the results of the histological examination (Student's t-test was 0.501, p=0.651). In each group, the pain syndrome was assessed in the postoperative period according to a 10-point pain scale after 3 hours, 8 hours, 24 hours, 3 days, 5 days and 10 days after surgical intervention. In the VAB group, the scores were significantly lower, p=0.000.
 The average number of bed-days in patients of the control group was 10.322.814, in the main group 1 day, the difference was statistically significant (p=0.000). The frequency of possible complications (hematoma, seroma, infection, deformity of the mammary gland, residual masses after removal) was significantly lower (p=0.013) in patients of the main group. When assessing the life quality of patients after surgery with the MOS SF-36 questionnaire, we found that the indicators were significantly higher in patients of the VAB group (Psychological Health Scale p=0.008, Social Functioning Scale p=0.003, Physical Condition Scale p=0.041).
