Immediate Prepectoral Breast Reconstruction Using an ADM with Smooth Round Implants – A Prospective Observational Cohort Study

Nanotechnology development in surgical applications: recent trends and developments

This paper gives a detailed analysis of nanotechnology's rising involvement in numerous surgical fields. We investigate the use of nanotechnology in orthopedic surgery, neurosurgery, plastic surgery, surgical oncology, heart surgery, vascular surgery, ophthalmic surgery, thoracic surgery, and minimally invasive surgery. The paper details how nanotechnology helps with arthroplasty, chondrogenesis, tissue regeneration, wound healing, and more. It also discusses the employment of nanomaterials in implant surfaces, bone grafting, and breast implants, among other things. The article also explores various nanotechnology uses, including stem cell-incorporated nano scaffolds, nano-surgery, hemostasis, nerve healing, nanorobots, and diagnostic applications. The ethical and safety implications of using nanotechnology in surgery are also addressed. The future possibilities of nanotechnology are investigated, pointing to a possible route for improved patient outcomes. The essay finishes with a comment on nanotechnology's transformational influence in surgical applications and its promise for future breakthroughs.

Highly biocompatible material for enhanced abdominal wall repair: a retrospective study with EGIS® porcine dermal matrix

In the early 2000s, medical devices based on acellular matrices multiplied in number. Nowadays, the use of porcine ADMs is to be considered a well-established technology, commonly applied in different surgical specialties. In this retrospective analysis of 110 cases, the use of non-crosslinked porcine ADM EGIS® results a safe and effective tool in many procedures and specialties.

Decellularization techniques of human foreskin for tissue engineering application

The rapid development of tissue engineering (TE) and regenerative medicine brings an acute need for biocompatible and bioactive biological scaffolds to regenerate or restore damaged tissue. Great attention is focused on the decellularization of tissues or even whole organs, and the subsequent colonization of such decellularized extracellular matrices by recipient cells. The foreskin is an integral, normal part of the external genitalia that forms the anatomical covering of the glans penis and the urinary meatus of all human and non-human primates. It is mucocutaneous tissue that marks the boundary between mucosa and skin. In this work, we compared two innovative decellularization techniques for human foreskins obtained from donors. We compared the efficacy and feasibility of these protocols and the biosafety of prepared acellular dermal matrixes that can serve as a suitable scaffold for TE. The present study confirms the feasibility of foreskin decellularization based on enzymatic or detergent methods. Both techniques conserved the ultrastructure and composition of natural ECM while being DNA-free and non-toxic, making it an excellent scaffold for follow-up research and TE applications.

Single-Institution Early Experience With a New, Smooth, Opaque, and Round Breast Implant Over a 2-Year Period

Background

The ideal breast implant does not exist and the choice of implant for breast augmentation is largely based on what surgeons think will be best for their patients.

Objectives

To evaluate the preliminary results of a new, smooth, round, and opaque breast implant (PERLE, GC Aesthetics; Dublin, Ireland) from a single-center UK aesthetic practice.

Methods

Retrospective cohort study of all patients undergoing breast implant surgery with PERLE at the authors' center between January 2021 and December 2022. Outcomes data such as rates of capsular contracture, infection, revision surgery, and synchronous mastopexy were analyzed.

Results

Of the 385 patients identified, 374 (97.1%) had PERLE implants placed by 3 surgeons for primary (n = 290) and secondary breast augmentation (n = 21), and augmentation-mastopexy (n = 63). Capsular contracture occurred in no cases, infection in 1 (0.2%), and revision surgery in 21 patients (5%). The incision used was always submammary, unless a synchronous mastopexy was performed; implants were placed in the subglandular/subfascial plane in the majority of cases (85.3%), and the rest were dual plane (14.7%). Eight revisions were performed in patients undergoing breast augmentation (due to implant displacement in 6 patients, and hematoma and infection in 1 patient each). Fourteen revisions were performed in those undergoing augmentation-mastopexy. The average follow-up time was 18 months.

Conclusions

The authors' early, single-center experience with PERLE implants suggests a safety profile and overall complication rate that is comparable with other modern implants. They will continue to monitor the safety and effectiveness of PERLE and discuss the reasons and evolution in the choice of breast implant.
