Use of a long term complete resorbable synthetic mesh in pre-pectoral implant-based breast reconstruction - results from the learning curve period
Zielsetzung The variability of different ADMs or synthetic meshes (non-, partial-, short- and long-term-resorbable) adds a new dimension of clinical research in breast reconstruction especially in patients with smooth implants. TIGR®-Matrix is a long term (approx. 36 months) complete resorbable mesh with anticipated benefits in short term e.g. implant stabilization and long-term follow up e.g. capsular contraction.
Materialien und Methoden A retrospective clinical-report-based documentation was done. Data analysis of our pre-defined learning curve focused on patient demographics, indication, feasibility; specific surgical techniques and short term cosmetic outcome were analyzed.
Ergebnisse From 08/2018 until 12/2019 36 Patients (median age 23-81) were analyzed. Primary operations as well as after primary systemic therapy with implant or expander independent on BMI; immediate or delayed reconstruction were performed. Shaping TIGR® individually into 4 different sling or pocket forms was established. Our preferences are sling techniques and individual intraoperative pocket-form, letter especially for smooth implants.
Cosmetic outcome was rated in > 85 % as very satisfied; tissue integration, low seroma volume, days with drains between 2,5 - 4 were reported. Handling and feasibility of TIGR®-Matrix + smooth implants in pre-pectoral implant position was easy and sufficient. A reconstructive failure occurs because of involved margins (2), wound infection (2) and wound dehiscence (1).
Zusammenfassung Use of TIGR®-Matrix enables an additional opportunity for pre-pectoral reconstructive techniques especially in combination with smooth implants; preserving the natural anatomy and lowers the risk of BIA-LCAL.
A prospective international multicenter AWOgyn-sponsored trial is initiated Q1/2020 to demonstrate patient reported outcome and safety parameters.
