ABSTRACT
Objective:To investigate the clinical efficacy of ultrasound-guided mammotomy versus conventional surgery in the treatment of benign breast tumors. Methods:Sixty patients with benign breast tumors who received treatment in Jiamusi Central Hospital from September 2018 to September 2019 were included in this study. They were randomly assigned to undergo either conventional surgery (control group, n = 30) or ultrasound-guided mammotomy (treatment group, n = 30). Intraoperative blood loss, operative time, incision length, and the incidence of complications were compared between the two groups. Results:Intraoperative blood loss, operative time, and incision length in the treatment group were (4.25 ± 1.23) mL, (15.36 ± 3.21) minutes, (0.41 ± 0.05) cm, respectively, which were significantly lower or shorter than those in the control group [(10.75 ± 2.12) mL, (29.68 ± 7.23) minutes, (2.9 ± 0.8) cm, t = 14.526, 9.915, 17.015, all P < 0.05]. In the treatment group, the incidence of complications was 3.33% (local hematoma n = 1, skin depression n = 0, flap necrosis n = 0, postoperative bleeding n = 0), which was significantly lower that 23.00% in the control group (local hematoma n = 2, skin depression n = 1, flap necrosis n = 1, postoperative bleeding n = 3, χ2 = 5.192, P < 0.05). Conclusion:Compared with the traditional treatment, ultrasound-guided minimally invasive mastectomy is more effective in the treatment of benign breast tumors.

ABSTRACT
OBJECTIVES: Vacuum-assisted breast biopsy (VABB) is a widely used technique for the diagnosis of breast lesions. It is carried out with local anesthesia, but procedural pain and stress are still problematic. Dexmedetomidine is a α-2 receptor agonist that can sedate without significant respiratory depression. The study aimed to report the effectiveness of sedation with monitored anesthesia care (MAC) using dexmedetomidine in VABB. METHODS: This was a retrospective chart review of patients who received VABB under MAC with dexmedetomidine. Forty-seven patients during the period of February 2015 to July 2016 were included. We collected data on patient characteristics, infusion drug and dose, induction to incision time, anesthetic, operation, and recovery time and other complications and vital signs. RESULTS: The mean operating time was 50.1 ± 24.9 minutes, and the anesthetic time was 71.2 ± 28.3 minutes. The mean time from induction to incision was 17.0 ± 5.2 minutes, and the recovery time was 20.1 ± 10.3 minutes. None of the patients needed an advanced airway management. Further, none of them showed hemodynamic instability. CONCLUSIONS: VABB was successfully performed with MAC using dexmedetomidine, and there was no respiratory depression or hemodynamic instability.
