Purpose: Seroma formation is a common complication in breast cancer patients undergoing mastectomy, and it negatively affects patient recovery after surgery. The present study aimed to evaluate a simple method using fascia suture technique to fix the flap and reduce the incidence of seroma. Methods: A single-center, prospective, randomized controlled trial was carried out among 160 patients who had undergone mastectomy from May 2018 to September 2019. All patients were randomly divided into the fascia suture group (n = 80) or control group (n = 80) and were followed up for at least 3 months for the assessment of immediate and late complications after surgery. Results: No significant differences were observed between the 2 groups with regard to the basic characteristics. Duration of surgery in the fascia suture group was longer by about 6 minutes compared with that in the control group (114.93 ± 13.67 minutes vs. 108.81 ± 15.20 minutes, p = 0.008). The fascia suture group had a shorter duration of drain placement (10.99 ± 3.26 days vs. 13.85 ± 5.37 days, p < 0.001), a smaller volume of the total drainage (460.95 ± 242.92 mL vs. 574.83 ± 285.23 mL, p = 0.007), and the first 3-day drainage (224.96 ± 101.01 mL vs. 272.3 ± 115.47 mL, p = 0.006), compared with the control group. The incidence of seroma formation (G2 or G3) was significantly lower in the fascia suture group compared with the control group (28.8% vs. 12.5%, p = 0.033). Besides, there was no statistical difference between the 2 groups in the assessment of other complications, including postoperative pain, hematoma, surgical site infections, flap necrosis, and skin dimpling (all p > 0.050). Conclusion: The fascia suture technique is a simple and effective method for reducing seroma formation and should be used to prevent seroma formation after mastectomy.

A magnetic field-driven photocurable superhydrophobic fabric coating technology was developed in this study. The coating, consisting of photoreactive carbonyl iron powder (CIP) assembled hydrophobic micro-nano structures, was constructed on the surface of polyester fabric by combining the magnetic field-driven assembly technology and blue light photocuring technology. Camphorquinone (CQ), ethyl 4-dimethylaminobenzoate (EDB) and diphenyliodonium hexafluorophosphate (DPI) were served as the photoinitiator formulation, while polyurethane diacrylate and hydroxyethyl acrylate (HEA) were used as the polymerization-cross-linking matrix for photocurable coating. Photo-differential scanning calorimetry (Photo-DSC) and rheometry were used to characterize the performance of coating formulations. Optical contact angle meter and scanning electron microscope (SEM) were used in combination with tensile performance test to explore the construction of superhydrophobic structure on coating surface induced by magnetic field. The optimal formulation of photoinitiators for coatings with excellent photopolymerization performance has been definitively established. Photocured coating film displayed a distinct hydrophobicity (the water contact angle is approx. 152.7°, and the sliding angle is approx. 7.2°) when the mass ratio of CIP to polymeric components was 1:1. The coated fabric eventually exhibited a satisfactory hydrophobicity (the water contact angle is approx. 153.3°) and mechanical properties.
