RESUMEN
BACKGROUND: Single-stage reconstruction using permanent expander implants is an established technique following mastectomy. Short and long-term outcome data following breast reconstruction using Becker tissue expanders is limited. METHOD: A retrospective case note review of patients undergoing expander-based procedures between 1989 and 2007 was undertaken. Data recorded included postoperative symptoms and complications, the use of radiotherapy, revisional surgery, and device failure. RESULTS: Three hundred and thirteen expanders were used in 276 patients with a mean age of 48.3 (17-78) years, over the 18 year study period. The mean follow up period was 64.6 (1-199) months. 256 Becker expanders were used during 175 latissimus dorsi (LD) and 52 subpectoral (SP) reconstructions, 13 contralateral augmentations and 16 implant replacements. The postoperative infection rate was 5.8%, leading to an expander loss rate of 3.8%. The use of prophylactic antibiotics was associated with an increased postoperative infection rate (p = 0.046). Six haematomas (2.5%) and 12 cases of skin envelope necrosis (5.0%) required unscheduled intervention. Symptoms of pain, distortion and hardness were experienced by 21.3% of patients, and radiotherapy was associated with a significantly higher risk of adverse symptoms (p < 0.0001). No patient developed symptomatic implant rupture or silicone granuloma but 17.9% of reconstructions underwent revisional surgery, the rate being highest following SP reconstruction (p = 0.029). Nine patients developed injection port complications (3.8%), and the overall device failure rate was 1.3%. The original expander has been retained by 74.2% of women. CONCLUSION: The Becker permanent expander is a reliable implant associated with a low complication rate and a high retention rate when used during breast reconstruction.

A patient with an accessory breast on the anterior abdominal wall was found to have cancer of this tissue, because of its unusual position it was decided that lymphatic mapping was necessary to identify the lymphatic drainage of this tumour. A metastasis was found in a sentinel node deep to the 'true' ipsilateral breast; however, the sentinel node identified in the axilla of this patient was free of metastases. The use of the sentinel node technique up staged the cancer from I to II and the patient went on to have adjuvant treatment with chemotherapy. The use of lymphatic mapping and sentinel node biopsy in the case of cancer of an accessory breast allows more accurate determination of lymph node status.
