Single-stage immediate breast reconstruction with acellular dermal matrix: Experience gained and lessons learnt from patient reported outcome measures

Single-Stage Immediate Breast Reconstruction with Acellular Dermal Matrix after Breast Cancer: Comparative Study and Evaluation of Breast Reconstruction Outcomes

We evaluate postoperative complications, aesthetic results and satisfaction outcomes in patients with breast cancer after intervening with a skin-sparing or nipple-sparing mastectomy with an immediate prosthetic reconstruction with or without a biological mesh. Patients with multifocal breast cancer, ductal carcinoma in situ with an indication for a mastectomy and cT2 tumors with no response to primary systemic treatment were included, whereas patients aged >75 years, with inflammatory carcinoma, and severe circulatory disorders were excluded. Patients in the control group were reconstructed using a prosthesis, whereas the study group included patients reconstructed using a prosthesis and biological acellular porcine dermal mesh (Strattice™). In both groups, the result was assessed using the BREAST-Q instrument. A total of 51 patients (62 intervened breasts) were included in the study group and 38 patients (41 intervened breasts) in the control group. Implant loss and removal occurred in three patients in the study group (5.9%) and nine patients in the control group (24.3%; p = 0.030). Infections appeared in three patients in the study group (4.8%) and three patients in the control group (7.3%; p = 1.00). Skin necrosis appeared in 5 patients in the study group (12.2%) and 11 patients in the control group (21.6%; p = 0.367). Seroma appeared in five patients in the study group (12.2%) and five patients in the control group (8.1%; p = 0.514). The BREAST-Q questionnaire is a comparison between both groups regarding "satisfaction with breasts after surgery" (p = 0.026), "sexual well-being after intervention" (p = 0.010) and "satisfaction with the information received" (p = 0.049). We have noted a statistically significant decrease in implant loss in women receiving an implant with a biological mesh. A higher satisfaction was observed in patients reconstructed using Strattice™, with statistically significant differences in three items.

Optimizing non-opioid pain control after implant-based breast reconstruction: a review of the literature and proposed pain control algorithm

Despite the intense focus on the opioid epidemic and its known association with surgical procedures, there is a paucity of evidence-based literature on pain management in implant-based breast reconstruction (IBR). Herein, we present an updated review of the literature aimed at identifying pain treatment protocols to minimize narcotic use and its associated potential addiction in IBR. A comprehensive review of the published English literature was conducted using Ovid Medline/PubMed Database without timeframe limitations. The inclusion criteria of selected articles presented in this review included studies reporting objective outcomes of pain modulation (preoperatively, intraoperatively and postoperatively) in IBR. Articles for inclusion were stratified based on intervention. A total of 219 articles were identified in the initial search query, with 23 studies meeting the inclusion criteria. Pain optimization interventions in IBR are herein summarized and analyzed based on the reported outcomes of each respective study. There is a substantial need for evidence-based guidelines in the plastic surgery literature for pain optimization without the use of opioids. While this review of studies to date investigates potential solutions, we hope this area of study continues to be a top priority for plastic surgeons to allow for optimized post-operative care for patients following IBR.

Submuscular and Pre-Pectoral ADM Assisted Immediate Breast Reconstruction: A Literature Review

Background and objectives: Breast cancer treatment has deeply changed in the last fifty years. Acellular dermal matrices (ADMs) were introduced for breast reconstruction, with encouraging results, but with conflicting reports too. The present paper aims to summarize the current data on breast reconstruction using acellular dermal matrices. Materials and Methods: We reviewed the literature regarding the use of ADM-assisted implant-based breast reconstruction. Results: The main techniques were analyzed and described. Conclusions: Several authors have recently reported positive results. Nevertheless, an increased complications' rate has been reported by other authors. Higher cost compared to not-ADM-assisted breast reconstruction is another concern.

Single stage immediate breast reconstruction with acellular dermal matrix and implant: Defining the risks and outcomes of post-mastectomy radiotherapy

INTRODUCTION

The objective of this study is to evaluate outcomes and complications in patients with single-stage ADM-implant based immediate breast reconstruction with and without radiotherapy (RT), highlighting the effects of RT on the reconstruction.

MATERIALS AND METHODS

This prospective study recruited 91 consecutive patients who underwent skin-sparing, nipple-sparing or wise-pattern skin reduction mastectomy with direct-to-implant breast reconstruction with ADMs using sub-pectoral or pre-pectoral approach at the two breast units. Early and late complications like seroma, delayed wound healing, wound breakdown, infection, capsular contracture, implant loss and revision surgery were evaluated in the RT and non-RT groups.

RESULTS

In the total cohort of 91 patients, 29 received adjuvant RT and 62 did not need RT. In the RT group, 3-7% of them had early complications like seroma, wound infections and delayed healing. 20.7% had post-RT capsular contractures which either required revision surgery with autologous flap (6.9%) or capsulotomy with exchange of implant (6.9%). In the non-RT group, 7-9% cases had seroma & wound infections, 3.06% had delayed wound healing and 7.25% had capsular contracture. 13.04% required revision surgery due to infection, implant loss or failure to achieve expectations. The total loss of implants in the cohort was 7.14% (RT group 6.9% and non-RT group 7.25%). The need for PMRT could have been predicted pre-operatively in the RT group in 55.17% cases based on the extent of disease, multifocality, tumour grade and positive LN status on imaging.

CONCLUSION

ADM based reconstruction in patients anticipated to receive adjuvant RT is always debatable. Though there is no significant difference in the revision surgeries in our study of the 2 groups, the rate of capsular contracture as expected, was higher in the RT group. Hence, pre-operative discussion on the need for RT highlighting the risks and complications will help patients make a better-informed choice.

TIGR matrix for implant-based breast reconstruction - a long-term resorbable mesh

The use of biological and synthetic meshes to aid implant coverage in implant-based breast reconstruction is well established. This technique allows single stage implant-based reconstruction compared to the traditional technique which required tissue expansion before permanent implant placement and therefore involved two operations for the patient. They can further be used for pre-pectoral implant reconstructions in a similar direct-to-implant strategy. This retrospective observational study by Pompei et al has evaluated the use of TIGR Matrix, a long-term resorbable mesh, in 49 patients with 60 operated breasts for both reconstructive and aesthetic cases. They have reported their operative method and followed up their cases for a mean of 12 months. They have reported a cumulative mesh complication rate of 5.4% and one implant was explanted due to infection. They identified a significant correlation between obesity and mesh-related complications. This study is significant as there remains little data regarding the long term outcomes of resorbable synthetic mesh for breast reconstruction. Their reported complication rates are consistent with those in other studies for synthetic meshes. As synthetic meshes can be significantly cheaper than their biological counterparts, this work could promote more widespread use.
