Acellular bovine pericardium matrix in immediate breast reconstruction compared with conventional implant-based breast reconstruction

Abstract

Background Acellular Bovine Pericardium Matrix (ABPM) is a new material in implant-based breast reconstruction (IBBR). Few studies have reported on its outcome and complications worldwide and most studies were without a control group. Our aim was to compare its use in IBBR with the other two conventional implant-based reconstruction methods. Methods A retrospective review of patients undergoing IBBR from January to December 2018 was performed. Patients were assigned to the ABPM-assisted IBBR (group A), latissimus dorsi-assisted IBBR (group B) and two-stage IBBR (group C). Patients’ post-operative complications, cost-effectiveness and Quality of Life were compared. Results 100 patients with 100 breasts were included in the study. No complications occurred in group C ( n = 11). No significant differences were noted between group A ( n = 44) and group B ( n = 45) in terms of overall complications (9.1% vs 11.1%, p = 0.973). Group B had the longest operative duration (310.8 ± 62.3 min, p <0.001). The cost of hospitalization forthe three groups was $8051.3 ± 849.2, $7566.0 ± 1172.7 and $7896.5 ± 1762.2, respectively ( p = 0.128). The postoperative Breast-Q scores were similar across the three groups. Conclusions ABPM demonstrated acceptable complication rates, cost-effectiveness and quality of life outcomes when compared to LD-assisted IBBR and two-stage IBBR.

Application of Tilapia Skin Acellular Dermal Matrix to Induce Acute Skin Wound Repair in Rats

“…Swelling ratio is an important index to evaluate the hydrophilicity of wound dressing agents, because higher swelling rate is beneficial to cell adhesion and osmotic growth ( Amirian et al, 2021 ; Tan et al, 2021 ; Wang S. et al, 2021 ). First, weigh the dry weight (D) of three samples (100 mg) TADM and FBADM scaffold, soak them with pure water, remove the surface water of the scaffold with filter paper, weigh the scaffold wet weight (W), and calculate the swelling rate of the acellular scaffold with the following formula: …”
