Evaluation of Prepectoral Implant Placement and Complete Coverage with TiLoop Bra Mesh for Breast Reconstruction: A Prospective Study on Long-Term and Patient-Reported BREAST-Q Outcomes

Prepectoral Two-Stage Implant-Based Breast Reconstruction with Poly-4-Hydroxybutyrate for Pocket Control without the Use of Acellular Dermal Matrix: A 4-Year Review

BACKGROUND

Absorbable mesh has been used to mitigate the potential drawbacks of acellular dermal matrix (ADM)-based breast reconstruction. Poly-4-hydroxybutyrate (P4HB) has been demonstrated to be a lower-cost, safe, and effective alternative to ADM in subpectoral breast reconstruction. In this study, the authors used P4HB for pocket control and implant support in immediate two-stage prepectoral breast reconstruction, examining nonintegration, capsular contracture, implant malposition, patient comorbidities, and risk factors.

METHODS

A retrospective review of a single surgeon's (K.M.) experience was performed over a 4-year span for patients who had undergone immediate two-stage prepectoral implant-based breast reconstruction with P4HB mesh. Complications (implant loss, rippling, capsular contracture, and malposition) and patient satisfaction were examined.

RESULTS

From 2018 to 2022, 105 patients underwent breast reconstruction using P4HB mesh on a total of 194 breasts. P4HB mesh integration was 97%. Sixteen breasts (8.2%) experienced minor complications, and 10.3% of devices required explantation, which was significantly higher in the irradiated group at 28.6% ( P < 0.01). Patients who were older, had a higher body mass index, were active smokers, or had an increased mastectomy specimen size were more likely to undergo explantation. The capsular contracture rate and overall lateral malposition rate were 1.0%. Visible rippling was present in 15.6% of breasts. There was no significant difference between smile mastopexy and inferolateral incision with regard to capsular contracture, lateral malposition, and rippling. Overall, patients demonstrated a high level of satisfaction. There were no significant predictors of capsular contracture, lateral malposition, or visible rippling.

CONCLUSIONS

The authors show the safety and efficacy of P4HB in two-stage prepectoral breast reconstruction. There appears to be equal, if not reduced, capsular contracture rates when compared with the published data on ADM. This represents a large cost reduction to both the patient and the health care system.

Clinical Outcomes of Transaxillary Reverse-Sequence Endoscopic Nipple-Sparing Mastectomy and Direct-to-Implant Prepectoral Breast Reconstruction: A Prospective Study of Initial 68 Procedures

BACKGROUND

Minimal access breast surgery improves cosmetic outcomes over conventional breast surgery but still faces barriers in becoming standard procedure for breast reconstruction. This report introduces a novel technique of transaxillary reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) followed by direct-to-implant prepectoral breast reconstruction (DTI-PBR) and describes its clinical outcomes.

METHODS

This prospective study enrolled patients who underwent R-E-NSM and DTI-PBR from March 2021 to December 2021 at a single institution. Perioperative data, surgical complications, oncologic outcomes, and patient- and surgeon-reported cosmetic results were noted.

RESULTS

The 60 patients in this study who underwent 68 R-E-NSM and DTI-PBR had a mean age was 40.4 ± 10.3 years. The average durations of uni- and bilateral operations were 156.5 ± 48.3 min and 191.3 ± 36.1 min, respectively. The overall surgical complication rate was 13.3%, including 10.0% of patients with minor complications and 3.3% of patients with major complications. The study had one case (1.7%) of implant loss and one case (1.7%) of skin flap necrosis treated by reoperation. During the median follow-up period of 24 months, one patient (1.7%) who discontinued chemotherapy for myelosuppression experienced liver metastases 5 months postoperatively, and one patient experienced new-onset contralateral ductal carcinoma in situ 24 months postoperatively. The preoperative and 18-month postoperative Breast-Q scores for satisfaction with breasts, psychosocial well-being, sexual well-being, and chest well-being did not differ significantly, and the Scar-Q was 81.2 ± 14.5 points. The good-to-excellent rate in surgeon-reported cosmetic results reached 90%.

CONCLUSIONS

Transaxillary R-E-NSM followed by DTI-PBR is a safe and efficient technique with high cosmetic outcomes and reliable medium-term oncologic results.

Application of TiLOOP bra in implant-based breast reconstruction is associated with decreased complication risk compared with other meshes: A systematic review and meta-analysis

BACKGROUND

TiLOOP bra has been used for over 15 years, however, evidence regarding its safety in implant-based breast reconstruction (IBBR) for patients with breast cancer after mastectomy is still limited. We performed this meta-analysis to evaluate its risks and benefits in IBBR comparing with other meshes.

METHODS

Electronic databases were searched to identify relevant studies comparing postoperative complications between TiLOOP bra and other reconstruction techniques in IBBR with or without meshes. We also compared patient satisfaction in physical well-being between two groups. Risk ratios (RRs) and mean differences with 95% confidence interval (CI) were calculated.

RESULTS

Seven studies representing 1203 cases were analyzed. Compared with other meshes, the use of TiLOOP bra significantly reduced the risk of infection (RR = 0.53, 95% CI, 0.32-0.86), seroma (RR = 0.21, 95% CI, 0.07-0.61), red breast syndrome (RR = 0.10, 95% CI, 0.02-0.45), and capsular contracture (RR = 0.20, 95% CI, 0.05-0.75). Patient satisfaction in physical well-being was comparable between two groups.

CONCLUSIONS

TiLOOP bra in IBBR has a favored safety profile over other meshes, which significantly reduced postoperative complication risk and did not affect patient satisfaction. Although prospective well-designed controlled studies are still warranted, TiLOOP bra is safe and reliable at present.

Patient-reported outcomes of mesh in minimally invasive (laparoscopic/robot-assisted) immediate subpectoral prosthesis breast reconstruction: a retrospective study

BACKGROUND

Although there is increasing interest in minimally invasive prosthesis breast reconstruction (PBR), whether meshes application in minimally invasive PBR can improve complications and cosmetic effects remains controversial. The author retrospectively analyzed postoperative complications and evaluated patient-reported quality-of-life outcomes in minimally invasive PBR with and without mesh.

METHODS

This study enrolled patients who underwent minimally invasive nipple-sparing mastectomy (NSM) followed by PBR. We used the TiLOOP bra for the mesh-assisted procedure. Patient demographics and postoperative complications data were compared between the procedures. Patient-reported outcomes were evaluated with the Breast-Q.

RESULTS

A total of 158 patients underwent 160 minimally invasive NSM-PBR (with mesh, n = 64; without, n = 94). Postoperative complications were comparable in the mesh-assisted (5 [7.7%]) and non-mesh-assisted (5 [5.3%]) groups (p = 0.533). The most common complication in non-mesh-assisted group was infection, with four (4.2%) cases. In mesh-assisted group, implant exposure occurred in two (3.1%) patients. Removal of prosthesis was uncommon, with two (3.1%) and three (3.2%) cases in the mesh-assisted and non-mesh groups, respectively (p = 0.977). The BREAST-Q questionnaire was completed by 52 (81.3%) patients in the mesh-assisted group and 68 (72.3%) in the non-mesh-assisted group. Comparing the non-mesh group, patients in mesh-assisted group had improved scores on the BREAST-Q Satisfaction with breast (66.0) (p < 0.05), Physical Well-being (80.0), and Sexual Well-being (56.0).

CONCLUSIONS

Mesh-assisted minimally invasive NSM-PBR has good aesthetic outcomes and high patient satisfaction. There were no significant differences in complication rates between the mesh-assisted and non-mesh-assisted groups.

Implant Based Breast Reconstruction Using a Titanium-Coated Polypropylene Mesh (TiLOOP® Bra): A Systematic Review and Meta-analysis

BACKGROUND

Implant-based breast reconstruction (IBBR) can be performed using a variety of biological and synthetic meshes. However, there has yet to be a consensus on the optimal mesh. This study investigates the safety and patient satisfaction of using TiLOOP® Bra in IBBR and compares its postoperative complication risk with that of porcine acellular dermal matrix (ADM) and SERAGYN® BR.

METHODS

The literature review was performed via PRISMA criteria, 23 studies met the inclusion criteria for the TiLOOP® Bra review, and 5 studies met the inclusion criteria for the meta-analysis. Patient characteristics and per-breast complications were collected. Data were analyzed using Cochrane RevMan and IBM SPSS.

RESULTS

In 3175 breasts of 2685 patients that underwent IBBR using TiLOOP® Bra, rippling was observed as the most common complication, followed by seroma and capsular contracture. No significant difference in the overall complication rate between pre- and sub-pectoral IBBR using TiLOOP® Bra. However, the meta-analysis showed that the TiLOOP® Bra group had significantly lower odds of implant loss, seroma, wound dehiscence, and the need for reoperation or hospitalization than the ADM group. Additionally, the TiLOOP® Bra group had a significantly lower seroma rate compared to the SERAGYN® BR group, while the other outcome indicators were similar between the two groups.

CONCLUSION

TiLOOP® Bra has become increasingly popular in IBBR in recent years. This review and meta-analysis support the favorable safety profile of TiLOOP® Bra reported in the current literature. The meta-analysis revealed that TiLOOP® Bra has better safety than ADM and a comparable risk of complications compared to SERAGYN® BR. However, as most studies had low levels of evidence, further investigations are necessary.

Technical Tips to Reduce Implant Rippling in Staged Pre-pectoral Breast Reconstruction

INTRODUCTION

Pre-pectoral implant-based breast reconstruction (IBR) is becoming increasingly popular, permitting optimal implant positioning on the chest wall, prevention of animation deformity, and reduced patient discomfort. There are, however, concerns related to increased rates of breast implant rippling in pre-pectoral (versus submuscular) IBR, which can prompt a patient to seek revisionary surgery. The aim of this study is to identify factors that can be implemented to reduce implant rippling in the setting of pre-pectoral IBR.

METHODS

A literature review was conducted using the PubMed database to determine the rate of rippling in pre-pectoral IBR. Clinical studies in English were included. Further review was then performed to explore technical strategies associated with reduced rates of rippling in pre-pectoral two-stage breast reconstruction.

RESULTS

Implant rippling has been reported with a rate varying from 0 to 53.8% in 25 studies of pre-pectoral IBR (including both direct-to-implant and two-stage IBR). The majority of studies reviewed did not demonstrate a significant association between BMI and rippling, suggesting that other factors, likely technical and device-related, contribute to the manifestation of implant rippling. Hence, we explored whether specific technical modifications could be implemented that would reduce the risk of rippling in patients undergoing pre-pectoral IBR. Specifically, we highlight the need for close attention to expansion protocol and pocket dimension, expander fill medium and implant characteristics, and the rationale behind adjunctive procedures to reduce implant rippling.

CONCLUSION

Surgical modifications may reduce the incidence of rippling in pre-pectoral breast reconstruction.

Comparative clinical outcomes of using three-dimensional and TIGR mesh in immediate breast reconstruction surgery for breast cancer patients

INTRODUCTION

Breast reconstruction (BR) surgery is a widely utilized approach for women who have undergone mastectomy. Using synthetic mesh can offer advantages over other materials providing long-lasting support and natural-looking results. This study aims to compare the effectiveness of 3DMax™ mesh to TIGR mesh in BR surgery, providing clear information about the non-inferiority of 3DMax™ mesh to TIGR.

METHODS

This retrospective cohort study evaluates postoperative complications in breast cancer patients who underwent subcutaneous mastectomy with direct-to-implant immediate BR using silicone implants and either 3DMax™ mesh or TIGR® Matrix Surgical Mesh.

RESULTS

This study involved BR surgeries in 82 patients, including 57 surgeries in the 3D mesh group and 49 in the TIGR mesh group. The two groups had no significant differences regarding age, body mass index (BMI), cancer stage, or surgical complications. However, patients with neoadjuvant chemotherapy or radiotherapy had higher incidence rates of long-term complications than other patients. Patients with infection or partial necrosis had a heightened risk of implant loss.

CONCLUSION

The clinical results obtained in this study suggest that among synthetic meshes used in immediate BR, 3DMax™ is not inferior to TIGR Matrix Surgical Mesh regarding complications.

A Scoping Review of the Application of BREAST-Q in Surgical Research

Background

Collection of patient-reported outcome (PRO) data can facilitate cost-effective, evidence-based, and patient-centered care. The BREAST-Q has become the gold standard tool to measure PRO data in breast surgery. The last review of its application indicated that it was underutilized. Considering the evolution in breast surgery, the purpose of this study was to perform a scoping review of BREAST-Q application since 2015 and identify emerging trends and potential persistent gaps to guide patient-centered practice and future research in breast surgery.

Methods

We performed an electronic literature review to identify publications published in English that used the BREAST-Q to assess patient outcomes. We excluded validation studies, review papers, conference abstracts, discussions, comments, and/or responses to previously published papers.

Results

We identified 270 studies that met our inclusion criteria. Specific data was extracted to examine the evolution of the BREAST-Q application and examine clinical trends and research gaps.

Discussion

Despite a significant increase in BREAST-Q studies, gaps in the understanding of the patient experience remain. The BREAST-Q is uniquely designed to measure quality of life and satisfaction with outcome and care. The prospective collection of center-specific data for every type of breast surgery will generate important information for the provision of patient-centered and evidence-based care.

How to convert a submuscular/dual plane reconstruction to a pre-pectoral pocket implant reconstruction

A conversion from subpectoral breast reconstruction to pre-pectoral breast reconstruction can help with animation resolution and improved patient satisfaction. We describe the conversion technique involving removal of the existing implant, creating a neo-pre-pectoral pocket and restoring the pectoral muscle to its natural position.

Surgical Delay of Nipple Areola Complex: A Powerful Technique to Extend the Indication of Nipple-Sparing Mastectomy

BACKGROUND

Surgical delay (SD) techniques, performed before the nipple sparing mastectomy (NSM), are procedures conceived to improve the blood supply to the nipple-areola complex (NAC) in order to overcome the ischemic risk. The aim of the study is reporting our experience with SD of the NAC in the setting of NSM, identify the rate of nipple and skin necrosis and other complications and to evaluate patient satisfaction with cosmetic outcome.

PATIENTS AND METHODS

A retrospective review of female patients, who underwent NSM and breast reconstruction between the July 2014 and the July 2019, was performed at the Breast Unit of San Giovanni-Addolorata Hospital in Rome. Eighty-nine NSM after SD procedure were performed in 66 patients. In all cases immediate breast reconstruction was performed with a direct to implant technique and polyurethane implants in prepectoral plan were used in all reconstructions.

RESULTS

We registered only 1 case of total NAC necrosis and 3 skin flap necrosis. Furthermore, patient satisfaction with breast reconstruction resulted excellent or good in 23 cases and good in 36 cases; the external plastic surgeon considered the breast reconstruction excellent or good in 63 cases.

CONCLUSION

We support the thesis that SD techniques may expand indications for NAC sparing mastectomy and immediate breast reconstruction in women with known risk factors for local complications. Microabstract This is the largest single center series on surgical delay of nipple areola complex providing interesting data on follow-up and complication rates and we support the thesis that surgical delay techniques may expand indications for nipple-areola complex sparing mastectomy and immediate breast reconstruction in women with known risk factors for local complications.

Postoperative Complications Following Prepectoral Versus Partial Subpectoral Implant-Based Breast Reconstruction Using ADM: A Systematic Review and Meta-analysis

BACKGROUND

There is a paucity of evidence comparing the safety of prepectoral and partial subpectoral implant-based breast reconstruction using acellular dermal matrices (ADM). We performed a meta-analysis to evaluate the postoperative complications of the two approaches.

METHODS

PubMed, EMBASE, Web of Science and Cochrane Library were searched to retrieve relevant articles. The rates of the complications were, respectively, pooled, and relative risk (RR) was estimated with 95% confidence intervals (CIs) to compare the incidence between the two cohorts.

RESULTS

Ten articles reporting on 2667 breast reconstructions were eligible. The hematoma rate was lower in the prepectoral group (RR  =  0.590, 95% CI 0.351-0.992). No significant difference was observed in terms of seroma (RR = 1.079, 95% CI 0.489-2.381), skin flap necrosis (RR = 0.936, 95% CI 0.587-1.493), infection (RR = 0.985, 95% CI 0.706-1.375), tissue expander/implant explantation (RR  =  0.741, 95% CI 0.506-1.085), wound dehiscence (RR = 1.272, 95% CI 0.605-2.673), capsular contracture (RR = 0.939, 95% CI 0.678-1.300) and rippling (RR = 2.485, 95% CI 0.986-6.261). The RR of animation deformity for the prepectoral group compared with the subpectoral group was 0.040 (95% CI, 0.002-0.853).

CONCLUSIONS

This systematic review suggested that with appropriate patient selection, prepectoral breast reconstruction could avoid animation deformity without incurring higher risk of early wound complications, capsular contracture or rippling than partial subpectoral breast reconstruction. Plastic surgeons should complete a comprehensive assessment of the patients before choosing appropriate surgical approaches in clinical practice.

Immediate breast reconstruction by prepectoral polyurethane implant: Preliminary results of the prospective study PreQ-20

INTRODUCTION

In recent years, mastectomy and reconstruction techniques have evolved towards less aggressive procedures, improving the satisfaction and quality of life of women. For this reason, mastectomy has become a valid option for both women with breast cancer and high-risk women. The objective of this study is to analyze the safety of mastectomy and immediate prepectoral reconstruction with polyurethane implant in women with breast cancer and risk reduction.

METHOD

Observational prospective study to evaluate the feasibility and safety of immediate reconstruction using prepectoral polyurethane implant. All women (with breast cancer or high risk for breast cancer) who underwent skin-sparing or skin-and-nipple-sparing mastectomy with immediate reconstruction with a prepectoral polyurethane implant were included. Women with breast sarcomas, disease progression during primary systemic therapy (PST), delayed, autologous or retropectoral reconstruction, and those who did not wish to participate in the study were excluded. Surgical procedures were performed by both senior and junior surgeons. All patients received the corresponding complementary treatments. All adverse events that occurred during follow-up and the risk factors for developing them were analyzed.

RESULTS

159 reconstructions were performed in 102 women, 80.4% due to breast carcinoma. Fourteen patients developed complications, the most frequent being seroma and wound dehiscence. Eight women required a reoperation (5.0%), seven of them due to implant exposure. Four reconstructions (2.5%) resulted in loss of the implant. Three patients progressed from their oncological process: a local relapse in the mastectomy flap, an axillary progression and a systemic progression.

CONCLUSIONS

Prepectoral reconstruction with a polyurethane implant is a procedure with a low incidence of postoperative complications (8.8%) and implant loss (2.5%). Its use is safe with perioperative cancer treatments (neoadjuvant chemotherapy and radiotherapy).

Double Asymmetric Circular Incision, a New Skin-Sparing Mastectomy Technique: Results and Outcomes of the First 46 Procedures

SUMMARY

Skin-sparing mastectomy (SSM) is a surgical technique that preserves as much of the breast skin as possible. Double asymmetric circular incision (DACI) is a novel immediate breast reconstruction technique for immediate prepectoral implant placement using a titanium-coated polypropylene mesh. The aim of this technique is to optimize the cosmetic benefits of smaller incisions, preserve breast anatomy, avoid breast deformities, and reduce the negative psychological impact on the patient without increasing local recurrence risk. DACI SSM uses a double circular incision: the external drawing contains the nipple-areola complex, while the inner circular skin island is used to provide the skin for the new areola. The authors performed DACI SSM in patients with tumors located within 2 cm of the nipple-areola complex, or in patients with multicentric lesions involving areolar tissue. Forty-six patients underwent DACI SSM at the authors' institutions between February of 2014 and July of 2019. Two patients developed hematoma, and one patient developed seroma. No implant loss was observed. Skin flap necrosis rate was 0%. The BREAST-Q patient-reported outcomes measure was routinely used at the authors' institutions and recorded good aesthetic outcomes and high patient satisfaction. This new technique appears to be safe and easily reproducible in patients with small to medium-sized breasts and with little to moderate ptosis (up to Regnault classification grade II).

Safety and Quality of Life in Women with Immediate Reconstruction with Polyurethane Implants after Neoadjuvant Chemotherapy: Outcomes from The Preq-20 Trial

INTRODUCTION

Various studies have evaluated the impact of neoadjuvant chemotherapy (NAC) on the complications of breast cancer surgery, most of which were retrospective and did not assess the variables related to postoperative risk factors. The aim of this study is to analyse the safety and satisfaction of women included in the PreQ-20 trial who underwent NAC and who underwent mastectomy and immediate reconstruction with prepectoral polyurethane implants.

MATERIAL AND METHODS

The patients included in the study belong to the prospective study PreQ-20. The study group consisted of patients who underwent immediate reconstruction after primary systemic therapy. The control groups consisted of patients with immediate reconstruction and adjuvant chemotherapy (control group 1) and patients with an infiltrating carcinoma or in situ ductal carcinoma who did not require chemotherapy (control group 2).

RESULTS

The study included 157 women, 58 (36.9%) of whom underwent primary systemic therapy. The indication for genetic study was significantly greater for the study group (87.9%) than for control groups 1 (49.1%) or 2 (30.4%). Seventy-two (45.9%) of the patients underwent bilateral mastectomy (BM), a procedure that was performed significantly more frequently in the study group (69%) than in control groups 1 (30.2%) or 2 (34.8%). The incidence rate for BM after complete pathologic response was 78%. There were no statistically significant differences in the number of complications between the groups. Implant loss was significantly more frequent in control group 1 (13.2%) than in the study group (3.4%) and control group 2 (2.2%).

CONCLUSIONS

Mastectomy with prepectoral polyurethane implant reconstruction in patients with neoadjuvant chemotherapy presented a similar incidence of complications compared with patients who underwent primary surgery. There is a high rate of BM in women with NAC.

Direct-to-Implant Subcutaneous Breast Reconstruction: A Systematic Review of Complications and Patient's Quality of Life

BACKGROUND

The use of direct-to-implant subcutaneous breast reconstruction has increased over the last years. The goal of this systematic review is to deliver an updated review of the safety of this technique and its impact on quality of life. We also compare subcutaneous vs submuscular complications, through meta-analysis.

METHODS

Literature review through PubMed and Cochrane Library databases were performed by PRISMA criteria. Thirty-nine studies met inclusion criteria for subcutaneous review and 15 studies met inclusion criteria for meta-analysis. All included studies were evaluated for complications and answers to the BREAST-Q. Data were analysed using Microsoft Excel, IBM SPSS, and Cochrane RevMan.

RESULTS

In 2863 patients and 3988 breasts that undergone direct to implant subcutaneous breast reconstruction, 8,21% had rippling, 5,64% seroma, 1,74% hematoma, 3,40% infection, 3,01% wound dehiscence, 3,93% skin necrosis, 3,34% nipple-areolar-complex (NAC) necrosis, 3,07% capsular contracture, 0,00% animation deformity, and 3,83% an implant removal. Meta-analysis showed a statistically significant decrease in the odds ratio of animation deformity, a but statistically significant higher odds ratio of rippling. Subcutaneous and submuscular reconstructions had similar BREAST-Q scores.

CONCLUSIONS

Direct-to-implant subcutaneous breast reconstruction does not harm the patient's quality of life, comparatively with submuscular, saving the pectoral muscle from dissection and preventing animation deformity, but increasing the risk of rippling.

Immediate Breast Reconstruction in Skin-Reducing Mastectomy with Prepectoral Polyuretane (Pu) Implant Covered with an Autologous Dermo-Adipose Flap

BACKGROUND

The aim of this study was to present our new technique of immediate breast reconstruction with prepectoral Polyuretane (PU) Implants, covered with an autologous dermo-adipose flap, in skin-reducing mastectomy both for risk-reducing (prophylactic mastectomy) and therapeutic cases.

METHODS

We performed a single-center, retrospective review of 21 patients (mean age 47 years), undergone skin-reducing mastectomy and immediate breast reconstruction with prepectoral Polyuretane (PU) Implants, covered with an autologous dermo-adipose flap, un the period January 2018-June 2021. All procedures were performed by the same surgeon.

RESULTS

A total of 36 skin-reducing mastectomies (6 curative, 15 prophylactic) with one-stage prepectoral PU foam-coated implant and autologous dermo-adipose flap reconstruction were performed. All postoperative complications were collected. Quality of life (QoL) and satisfaction with reconstruction were evaluated through the BREAST-Q questionnaire, administered preoperatively and at 12 months after surgery. Independent Student's t tests were used to compare means of continuous variables and Chi-square test was used for ordinal variables. A p-value ≤0.05 was considered statistically significant. Uni- and multiple linear regression analyses were used to confirm all results. Out of 21 patients, we observed one small wound dehiscence and one partial Nipple-Areola Complex (NAC) necrosis. All cases of minor complications were managed conservatively and did not affect the quality of the final outcome. No implant loss was observed. No significant severe capsular contracture (grade III or IV) was detected at follow-up. Overall satisfaction with breasts, psychosocial, physical and sexual well-being all significantly increased, analyzing BRAST-Q data. Statistical analysis showed a significant influence of diabetes on the risk of complications.

CONCLUSIONS

Our experience suggests that the procedure described is effective, feasible and cost-effective. It is easier to perform compared to similar and more demanding procedure, reduces operative time, and minimizes complications related to manipulation of the pectoralis major muscle, while also contributing to the containment of costs. Moreover, it appears to be oncologically safe, provides good esthetic results with low postoperative complication rate and leads to high level of patients' satisfaction.

Controlateral Symmetrisation in SRM for Breast Cancer: Now or Then? Immediate versus Delayed Symmetrisation in a Two-Stage Breast Reconstruction

Introduction: The timing of contralateral symmetrisation in patients with large and ptotic breasts undergoing a unilateral skin-reducing mastectomy (SRM) is one of the most debated topics in the reconstructive field. There is no evidence to support the advantage of immediate or delayed symmetrisation to help surgeons with this decision. The aim of this study was to investigate the clinical and aesthetic outcomes of immediate symmetrisation. Methods: A randomised observational study was conducted on patients who underwent an SRM for unilateral breast cancer. Based on a simple randomisation list, patients were divided into two groups: a delayed symmetrisation group versus an immediate symmetrisation group. The postoperative complications, BREAST-Q outcomes and reoperations were compared. Results: Out of a total of 84 patients undergoing an SRM between January 2018 and January 2021, 42 patients underwent immediate symmetrisation and 42 patients had delayed symmetrisation. Three implant losses (7.2%) were observed and we reported three wound dehiscences; one of these was in a contralateral breast reconstruction in the immediate symmetrisation group. The BREAST-Q patient-reported outcome measures recorded better aesthetic outcomes and a high patient satisfaction for the immediate symmetrisation group. Conclusions: Simultaneous controlateral symmetrisation is a good alternative to achieve better satisfaction and quality of life for patients; from a surgical point of view, it does not excessively impact on the second time of reconstruction.

“Hook Shape” Nipple-Sparing Mastectomy and Prepectoral Implant Reconstruction: Technique, Results and Outcomes from a Preliminary Case Series

INTRODUCTION

Nipple-sparing mastectomy (NSM) is a surgical procedure increasingly performed for breast cancer or risk reduction surgeries. The site of skin incision seems to affect not only cosmesis but also technical ease in operating and vascular viability of the nipple. We present a series of patients who underwent a modified vertical surgical approach for NSM, which resulted to be safe, reliable, and with good esthetic results.

MATERIALS AND METHODS

From December 2016 to February 2019, 27 "Hook Shape" incision NSMs were performed. All patients underwent an immediate subcutaneous muscle-sparing reconstruction with tissue expander covered by a titanium-coated polypropylene mesh, followed by a second surgical step with expander substitution and lipofilling on the definitive implant when indicated. Preoperative and postoperative BREAST-Q patient-reported outcomes measure was performed in all cases.

RESULTS

Postoperative morbidity was evaluated: One patient developed seroma and another presented a systemic infection that resolved with intravenous infusion of antibiotics. One patient experienced vertical wound dehiscence, recovered after conservative treatment and without implant exposure. No implant loss was observed. Nipple-areola complex necrosis or ischemia rate was 0%. The BREAST-Q outcomes reported significant increases in the overall satisfaction with breast (p < 0.05), psychosocial well-being (p < 0.05), and sexual well-being (p < 0.05) sections. Scores in the physical impact of surgery section appeared to decline from preoperative to postoperative evaluations, with no statistically significant results.

CONCLUSION

The mastectomy incision pattern can burden the surgical challenge, impact vascular viability of the nipple and significantly affect the aesthetic outcomes in breast reconstruction. We report our experience with an alternative approach for NSM, which appears a safe, practical, and reproducible method for patients with small- to medium-sized breasts and little/medium ptosis (grade I or II).

Immediate Breast Reconstruction with Prosthesis and Titanized Mesh Using a Dual-Plane Approach: Complications and Risk Factors Analysis

INTRODUCTION

The immediate breast reconstruction after mastectomy has gained prominence in recent years and is considered one of the main procedures in oncoplastic surgery. In the case of reconstruction with prostheses, the use of a mesh to extend the pectoralis major muscle is often required to partially cover the implant. The main objective of this study was to determine the percentage of complications in immediate breast reconstructions with a titanized mesh using a dual-plane approach and establish risk factors for prosthesis complications and extrusion.

MATERIALS AND METHODS

A retrospective study that included women who received postmastectomy reconstructions from January 2012 to December 2019 in a secondary hospital in Spain.

RESULTS

A total of 57 immediate reconstructions were performed in 47 women. There were complications in 16 mastectomies (28.1%), of which seven (12.3%) were Clavien-Dindo ≤ IIIa and nine (15.7%) were IIIb. A total of three patients presented prosthetic extrusion, and the prosthesis was removed in five. The degree of contracture according to the Baker scale was I-II in 50 mastectomies (87.7%) and III-IV in seven (12.3%).

CONCLUSION

The immediate breast reconstruction with a titanized mesh using a dual-plane approach is a technique with an acceptable percentage of complications. The need for a Wise pattern and the necrosis of the nipple-areola complex in the postoperative period are risk factors for implant loss. Patients undergoing radiotherapy and/or chemotherapy and with a previous surgery are more likely to present capsular contracture.

"Just Pulse it!" Introduction of a conservative implant salvage protocol to manage infection in pre-pectoral breast reconstruction: Case series and literature review

Post-operative implant infection is generally rare after breast augmentation, but it can occur in up to 35% of cases in post-mastectomy breast reconstruction. Standard treatment consists in the administration of antibiotics, implant removal, and delayed prosthesis replacement leading to multiple operations, with a negative impact on patient's clinical, economical, and psychological outcomes. There is little information published in the literature on the management of periprosthetic infection following pre-pectoral reconstructions. Capsule's removal from a pre-pectoral plane brings the risk of excessive tissue thinning and the compromise of skin flaps viability. In this preliminary multi-center case series, eight patients diagnosed with implant infection following oncological mastectomy and two-stage heterologous pre-pectoral breast reconstruction underwent the same protocol, consisting in tissue expander removal and conservative surgical revision supplemented by an antibiotate pulse lavage of the pocket surface. All patients achieved a successful infection resolution with immediate prosthesis replacement switching the temporary expander to definitive implant. No additional surgical revision was registered during follow-up. The intermittent irrigation is meant to disrupt the biofilm structure and restore antibiotic susceptibility. Moreover, pulse lavage allows the cleansing of the prosthetic capsule, thus avoiding the vascular stress associated with subcutaneous capsulectomy. To the best of our knowledge, this is the first series reporting on the use of Pulsavac in periprosthetic infection following pre-pectoral breast reconstruction, in an attempt to set the basis for an alternative conservative protocol to manage breast implant infection. A thorough literature review on pulse lavage in breast surgery was carried out.

Prepectoral implant-based breast reconstruction with TiLOOP® Bra Pocket - a single-centre retrospective study

BACKGROUND

Prepectoral implant-based reconstruction using synthetic meshes is feasible with good outcomes. We present our data using TiLOOP® Bra Pocket, a novel ready-to-use mesh pocket which acts as an internal bra and prevents the implant from dislocating or twisting.

MATERIALS AND METHODS

A single-centre retrospective cohort study was performed to assess short-term complication rates and cosmetic outcomes in patients with prepectoral implant-based reconstruction using the TiLOOP® Bra Pocket. The primary endpoint was complication rates during the first 6 months. The secondary endpoint was the cosmetic outcome after 6 to 12 months, which was judged by two breast surgeons using the Harvard score.

RESULTS

A total of 63 breasts (43 patients) were reconstructed using the TiLOOP® Bra Pocket between 2018 and 2020, 57 were immediate reconstructions. The overall complication rate was 30,2% (n = 19/63). Major complications occurred in seven breasts (n = 7/63; 11,1%) and minor complications occurred in 12 breasts (12/63; 19,0%). The unplanned revision rate was 12,7%. The cosmetic outcome was good (Harvard score: mean 3, range 1-4; SD 0,75). Seventeen cosmetic complications were observed (17/63; 27,0%) and six cosmetic revision surgeries were performed (6/63; 9,5%).

CONCLUSION

The use of the TiLOOP® Bra Pocket is convenient and standardized because the pocket is preformed and does not require to be sewn first. Cosmetic outcome is good; however, the surgical morbidity needs to be addressed in future reconstructions. Careful patient selection and preparation techniques are vital in order to achieve acceptable complication rates and satisfying cosmetic results.

Histological evaluation of capsules formed by texturized silicone implants with and without polyester mesh coverage (Parietex®). A study on female rats

Purpose

To evaluate capsules formed by microtextured silicone implants with and without Parietex® mesh coverage histologically.

Methods

Sixty Wistar rats were divided in two groups (meshed and unmeshed). Each group was, then, divided into two subgroups for evaluation at 30 and 90 days. Capsules were analyzed based on hematoxylin and eosin (HE) and picrosirius staining.

Results

The number of fibroblasts, neutrophils and macrophages was similar among all subgroups. There was a higher lymphocyte reaction in the 30-day meshed group (p = 0.003). Giant cell reaction, granulation tissue and neoangiogenesis were similar among the subgroups. Synovial metaplasia was milder at 90-day in the unmeshed (p = 0.002) and meshed group (p < 0.001). Capsular thickness was significantly greater in the meshed samples (30-day p < 0.001 and 90-day p < 0.001). There was a similar amount of collagen types I and III in both groups.

Conclusions

The mesh-covered implants produced capsules similar to the microtextured ones when analyzing inflammatory variables. Synovial metaplasia was milder at 90 than at 30 days, and the capsular thickness was significantly greater in the meshed group. A similar amount of collagen types I and III was observed. Due to these characteristics, the mesh coverage did not seem to significantly affect the local inflammatory activity.

Titanium-coated polypropylene mesh as innovative bioactive material in conservatives mastectomies and pre-pectoral breast reconstruction

Breast reconstruction is rapidly evolving, thanks to the growing acceptance of synthetic meshes as innovative biomaterials. 276 patients undergoing mastectomy (total of 328 mastectomies) were analyzed in a retrospective observational study to evaluate the pre-pectoral immediate breast reconstruction (IBR) using an implant wrapped with Titanium-Coated Polypropylene Mesh (TCPM) vs. patients treated with tissue expander (TE), equally placed pre-pectorally (and wrapped with the same TCPM in 74.3% of the control group’ breasts). 163 patients, of the study group (SG), underwent mastectomy and pre-pectoral IBR with implant wrapped with TCPM, in a one-step surgery, called direct-to-implant technique (DTI), while 113 patients control group (CG) underwent mastectomy and TE. DTI technique has been performed in 192 breasts of the SG while TE procedure in 136 breasts of the CG. The BREAST-Q questionnaire has been provided before the treatment and 2 years later. Baker scale has been used to evaluate capsular contracture. Oncologic, surgical, and aesthetic outcomes along with BREAST-Q scores were analyzed. Additionally, a histologic evaluation was conducted in 11 capsules' samples randomly chosen (6 derived from SG patients and 5 derived from CG). Complications were recorded in 43 cases (29SG-14CG): 8 skin-nipple necrosis (5SG-3CG), 8 wound dehiscence (6SG-2CG), 3 hematomas (1SG-2CG), and 24 infections (8SG-16CG). Grade IV capsular contracture was detected in 9 breasts (1SG-8CG), whereas 254 breasts were grade I (110SG-144CG), 33 (10SG-23CG) grade II, and 32 (4SG-28CG) grade III. Implant wrinkling was detected in 18 cases (10SG-8CG) after 30 months. The local tumor recurrence rate was 5.8%. Three recurrences were on the nipple-areola complex (1.9%). SG patients showed significantly higher rates in the BREAST-Q overall Satisfaction with Outcome (74.1), overall Satisfaction with Breasts (69.1), Psychosocial Well-being (81.9), and Sexual Well-being (63.1), versus CG's patients (p < 0.05). Histological analysis showed a process of normal tissue repair with a complete mesh integration and normal healing. Conservative mastectomies with pre-pectoral IBR assisted by TCPM proved themselves oncologically safe, biologically integrated into native tissues, and highly accepted in terms of quality of life guaranteeing a more natural and aesthetic breast appearance.

Core tip

This retrospective observational study provided clinical and histological outcomes of the pre-pectoral IBR using an implant wrapped with TCPM vs. patients treated with TE, equally placed pre-pectorally. The efficacy of IBR using an implant wrapped with TCPM was confirmed by the cosmetic results obtained and by a rate of side effects comparable to TE. All the histological analyses performed confirmed the TCPM mesh complete integration with the physiological aspects of healing: The Collagen 1 and 3 expressions did not differ, between TCPM and NO TCPM samples to confirm a process of healing overlapping to perfect device incorporation and normal healing.

•

This retrospective observational study, reports the results of pre-pectoral immediate breast reconstruction (IBR) using a prosthesis wrapped with Titanium-Coated Polypropylene Mesh (TCPM) vs. patients treated with tissue expander (TE) equally placed pre-pectorally (and wrapped with the same TCPM in 74% of the control group), with the aim to reduce the risk of reconstruction failure after conservative mastectomy.

•

The primary end-points of the study were the clinical outcomes. These outcomes were: the incidence of perioperative and postoperative complications (safety profile), quality of life (QoL) at 2 years after surgery, measured as the change between the pre- and post-op BREAST-Q scores, the aesthetic outcomes, and the capsular contracture grade. Two methods for the clinical analysis of the results have been used: Surgical-Team and patient self-evaluation. The Surgical-team evaluation was an objective evaluation based on clinical assessment, using a scale of six degrees (excellent, good, discreet, enough, poor, inadequate). The subjective patient-based self-evaluation applied the same six degrees. Moreover, secondary end-point of the study, was a histopathological capsule assessment to evaluate the integration of the TCPM in the mastectomy flap as a bioactive material.

•

Histological, and bio-molecular evaluation of TCPM samples were analyzed. In particular, Hematoxylin-eosin staining of post-operative biopsies of wrapping tissue TCPM mesh was performed focusing on the collagen presence and fibroblasts amount and specifically, on the complete healing and TCPM incorporation without side effects. Additionally, the immunofluorescence using specific markers CD 45 and Collagen 1, and immunohistochemistry using CD 45 on paraffin samples were performed. The endpoint was to evaluate the grade of inflammation represented by the number of lymphocytes in the treated site, and the eventual different collagen type expression (Collagen 1 and Collagen 3) in tissues underwent and not to radiotherapy and during the use of TCPM.

•

Analyzing the side effects with the use of t-test, the complication rate between SG and CG did not showed statistically significant differences (p=0,8472), although it was slightly higher in the SG. Despite the study group was bigger than the control group (+42%) the side effects' number did not statistically differ, confirming the safety and reliability of the TCPM procedure during DTI. Overall Satisfaction with Breasts, Psychosocial Well-being, and Sexual Well-being scores were all significantly increased after sub-cutaneous pre-pectoral DTI immediate reconstruction with TCPM mesh (p < 0.05) compared to CG. Mean satisfaction with the overall aesthetic result was high after breast reconstruction (8.72) in patients who underwent DTI pre-pectoral immediate reconstruction (SG) after 2 years from surgery.

•

The histological analysis of fragments of implant's wrapping tissue incorporating TCPM mesh displayed complete incorporation of the mesh with physiological aspects of healing. The immunochemistry concluded the Collagen 1, and 3 expressions did not differ, with statistical significance, between TCPM and NO TCPM samples, showing a process of physiological healing overlapping to perfect device incorporation, confirming that TCPM was a bioactive material. Conservative mastectomies with pre-pectoral IBR assisted by TCPM are resulted oncologically safe preserving breast appearance.

"To Pre or Not to Pre": Introduction of a Prepectoral Breast Reconstruction Assessment Score to Help Surgeons Solving the Decision-Making Dilemma. Retrospective Results of a Multicenter Experience

BACKGROUND

Implant-based reconstruction is the most performed breast reconstruction, and both subpectoral and prepectoral approaches can lead to excellent results. Choosing the best procedure requires a thorough understanding of every single technique, and proper patient selection is critical to achieve surgical success, in particular when dealing with prepectoral breast reconstruction.

METHODS

Between January of 2014 and December of 2018, patients undergoing mastectomy and eligible for immediate prepectoral breast reconstruction with tissue expander or definitive implant, were selected. The Prepectoral Breast Reconstruction Assessment score was applied to evaluate patient-related preoperative and intraoperative risk factors that could influence the success of prepectoral breast reconstruction. All patients were scored retrospectively, and the results obtained through this assessment tool were compared to the records of the surgical procedures actually performed.

RESULTS

Three hundred fifty-two patients were included; 112 of them underwent direct-to-implant immediate reconstruction, and 240 underwent the two-stage procedure with temporary tissue expander. According to the Prepectoral Breast Reconstruction Assessment score, direct-to-implant reconstruction should have been performed 6.2 percent times less, leading to an increase of 1.4 percent in two-stage reconstruction and 4.8 percent in submuscular implant placement.

CONCLUSIONS

To date, there is no validated system to guide surgeons in identifying the ideal patient for subcutaneous or retropectoral breast reconstruction and eventually whether she is a good candidate for direct-to-implant or two-stage reconstruction. The authors processed a simple risk-assessment score to objectively evaluate the patient's risk factors, to standardize the decision-making process, and to identify the safest and most reliable breast reconstructive procedure.

Breast Animation Deformity: A Retrospective Study on Long-Term and Patient-Reported Breast-Q Outcomes

BACKGROUND

We evaluated the aesthetic outcomes and quality of life of patients who underwent neurotomy of the lateral and medial branch of the pectoralis nerve for animation deformity after breast reconstruction.

MATERIAL AND METHODS

Health-related quality of life questionnaire and cosmetic outcome evaluation were conducted using the preoperative and the postoperative BREAST-Q modules for reconstructive surgery. An external author also assessed the general aesthetic outcome before and after surgery.

RESULTS

Sixty-two patients with animation deformity after breast reconstruction were enrolled: 43 in group 1 (second-stage breast reconstruction), 10 in group 2 (permanent breast prosthesis), and 9 in group 3 (Baker III-IV capsular contraction). Patients scored high level of satisfaction with outcome concerning all aspects of the survey. Overall satisfaction with breast was significantly increased after surgery in all the 3 groups, whereas physical well-being was improved in group 1 and group 3 and psychosocial well-being was improved in group 1. General outcome evaluation by an external author, compared with the preoperative condition, also showed significant improvement.

CONCLUSIONS

Section of the lateral and medial branches of the pectoralis nerve represents an easy and reproducible technique, associated with low morbidity and very good results in terms of patient satisfaction, comfort, and hospitalization.

Extended Latissimus Dorsi Kite Flap (ELD-K Flap): Revisiting an Old Place for a Total Autologous Breast Reconstruction in Patients with Medium to Large Breasts

BACKGROUND

The latissimus dorsi (LD) flap represents one of the most reliable methods for autologous breast reconstruction. However, in many patients, the exclusive use of this technique may not guarantee the restoration of an adequate volume and projection. We report our experience with the extended latissimus dorsi kite flap (ELD-K flap), an alternative surgical approach to maximize the volume of the fleur-de-lis pattern LD flap, for total autologous breast reconstruction.

METHODS

Between 2016 and 2018, 23 patients were subjected to mastectomy and immediate autologous reconstruction with "extended latissimus dorsi kite flap" (ELD-K flap), technique that employs an extended version of the LD musculocutaneous flap, based on the skeletonized thoracodorsal pedicle and a trilobate skin incision with an inferiorly based vertical branch. The BREAST-Q questionnaire was administered preoperatively, and one year after surgery to evaluate the quality of life results of the patients. BREAST-Q latissimus dorsi module was also provided.

RESULTS

Average body mass index was 29.7 kg/m² (range 25-40 kg/m²). Mild complications occurred in only six cases, and eight patients underwent treatment to improve the donor site scar outcome. Patients indicated high scores in quality of life measures with an increase in all BREAST domains from the preoperative to the postoperative period. A statistically significant increase (p < 0.05) was noted in: "overall satisfaction with breasts" (p < 0.05), "psychosocial well-being" (p < 0.05), "physical impact of the surgery" (p < 0.05). Within the LD module, participants reported a mean score of, respectively, 73.8 and 67.9 for "satisfaction with back" and "satisfaction with shoulder and back function" domains.

CONCLUSIONS

The extended incision allows the recruitment of additional tissue to provide enough volume to complete the reconstruction without implants. The isolation of the vascular pedicle allows for extreme freedom and mobilization of the flap, ensuring adequate filling of the breast. ELD-K flap may expand the indications for a total autologous LD immediate breast reconstruction, representing an additional and reliable alternative in selected cohorts of patients.

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

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.

Pre-pectoral one-stage breast reconstruction with anterior biological acellular dermal matrix coverage

Background

Pre-pectoral implant breast reconstruction (IBR) is gaining popularity. Several techniques using different types of meshes and methods of placement have been described, but no method is currently considered standard. The aim of this study was to evaluate the outcomes of pre-pectoral IBR using acellular dermal matrix (ADM) for anterior implant cover.

Methods

Retrospective cohort study of consecutive patients who underwent pre-pectoral IBR between November 2016 to August 2018. Data on demographics, adjuvant therapies and operative technique was collected. Postoperative complications, length of hospital stay and secondary cosmetic procedures were recorded. Statistical analysis was performed using descriptive statistics, non-parametric tests and logistic regression.

Results

One hundred and eleven pre-pectoral IBR were performed in 65 patients. Median age was 41 [interquartile range (IQR), 35-51.5] years, and BMI 22 (IQR, 20.4-24.4) kg/m². Therapeutic mastectomy was performed in 33 procedures with nipples preservation in 78 cases. The median mastectomy weight and implant volume was 360 (IQR, 220-533) gr, and 445 (IQR, 400-475) cc respectively. At a median follow-up of 18 (IQR, 12-22.5) months, 37 mastectomies had at least 1 complication, but only 12 required surgery. The implant loss rate was 4.5% (5 cases). Lipofilling as secondary procedure was performed in 10.8% of cases. Factors associated with post-operative complications on univariate analysis were nipple preservation (P=0.028), BMI (P=0.01) and implant volume (P=0.027) but these did not remain significant on multivariate analysis.

Conclusions

Pre-pectoral IBR using ADM for anterior implant cover is associated with low complication and reconstructive failure rate. Patient selection and meticulous surgical technique are important for successful outcome.

Immediate prepectoral implant reconstruction using TiLOOP Bra Pocket results in improved patient satisfaction over dual plane reconstruction

BACKGROUND

Implant-based reconstruction accounts for the majority of breast reconstructive procedures performed in Australia. More recently, immediate prepectoral implant reconstruction using the TiLOOP Bra Pocket has gained popularity. This study compares post-surgical complications and patient-reported quality of life outcomes between immediate prepectoral and dual plane implant reconstruction.

METHODS

A retrospective study of 80 consecutive patients who underwent nipple-sparing mastectomies and immediate implant reconstruction was conducted. Implants were either completely covered with TiLOOP Bra and/or TiLOOP Bra Pocket (pfm medical, Cologne, Germany) and secured in the prepectoral space (prepectoral group) or placed in the subpectoral plane with inferolateral mesh coverage (dual plane group). Data surrounding patient demographics, clinical details and post-surgical outcomes were compared. Patient-related quality of life outcomes were assessed with the Breast-Q questionnaire.

RESULTS

A total of 80 patients (109 breasts) operated on between June 2016 and December 2018 were included. The prepectoral and dual plane groups comprised of 40 patients each, including 50 and 59 operated breasts, respectively. Post-operative complications were comparable with 11 (22%) overall complications in the prepectoral group and eight (14%) in the dual plane group (P = 0.313). Implant loss was uncommon with four (8%) cases in the prepectoral group and five (8.5%) in the dual plane group (P = 0.929). Patient-reported quality of life outcomes were superior after prepectoral reconstruction with patients reporting a significantly higher score in the satisfaction with breasts domain (68.9 versus 57.5; P = 0.036).

CONCLUSION

Immediate prepectoral implant reconstruction with the TiLOOP Bra Pocket was associated with improved patient satisfaction and demonstrated no difference in early post-operative outcomes.

Thoracic migration of silicone gel after breast implant rupture: a case report and literature review

Nowadays silicone is a widespread material for medical devices. In particular, it is commonly used for implants manufacturing, for that patients undergoing breast augmentation or breast reconstruction after mastectomy. However, the use of silicone implants is not free from risks. Ruptures of silicone breast implants are uncommon, in general post-traumatic or iatrogenic, and usually related to implant’s wall weakness of unknown origin but probably due to biochemical reactions that cause wall rupture. As a consequence of a rupture, silicone gel from damaged implants may have a continuity migration to the chest wall, axillae, and upper extremities, resulting in granulomatous inflammation or siliconoma, or a lymphatic migration to axillary lymph nodes. In this regard, silicone thoracic migration is extremely rare, and nowadays a leakage is unlikely to happen with more modern cohesive silicone gel implants. Nevertheless, procedures such as thoracic surgery and thoracotomies may be responsible for accidental breast implant rupture, capsular discontinuity, and eventually intrathoracic silicone migration, especially when dealing with older generations of breast implants. We report a rare case of a 75-year-old woman presenting with pleural silicone effusion, 18 years after a right breast reconstruction for breast cancer, followed by right upper lobe resection for a lung carcinoma. A combination of muscular flap and DTI pre-pectoral breast reconstruction with biological membrane (ADM) has been used for treatment. Literature was reviewed for cases of breast implants free silicone localization in the chest cavity, focusing on previous surgeries, anamnestic relevances, and surgical management.

Dual-Plane Retro-pectoral Versus Pre-pectoral DTI Breast Reconstruction: An Italian Multicenter Experience

Background

The use of conservative mastectomies has risen significantly during the last few years. The reconstructive choice of direct-to-implant reconstruction has become more practicable with modern mastectomy techniques. The initial trend in Italian centers was to use dual-plane hybrid reconstruction. However, a high level of complications has been registered. From 2015 onward, in our centers, a pre-pectoral approach has been adopted. The authors sought to describe the Italian trend to gradually discard the sub-pectoral technique with lower lateral pole coverage of the prosthesis using ADMs comparing it with the pre-pectoral approach with ADMs, without any muscle dissection, in terms of complication rates.

Materials and Methods

A multicenter retrospective clinical study was performed from January 2010 to June 2018. The enrolled patients were divided into two groups: Cases with an ADM-only coverage pre-pectoral reconstruction made up the first group (Group 1). Those with the retro-pectoral muscular position + ADM implant coverage comprised the second one (Group 2). Complications such as seroma, hematoma, wound dehiscence, surgical site infection, reconstruction failure, animation deformity and capsular contracture were recorded.

Results

We performed 716 direct-to-implant reconstructions: 509 were partially sub-pectoral and 207 were pre-pectoral. Minimum follow-up was 1 year. Incidence of complications was higher in dual-plane reconstructions. There were statistical significant differences in the rates of seroma and hematoma.

Conclusion

Using the pre-pectoral approach, the authors have experienced favorable aesthetics and superior clinical and functional outcomes. Retro-pectoral muscular ADM implant coverage has to be considered only in specific complicated second-stage surgeries.

A prospective study on combined lymphedema surgery: Gastroepiploic vascularized lymph nodes transfer and lymphaticovenous anastomosis followed by suction lipectomy

BACKGROUND

There is no consensus on the appropriate treatment of lymphedema. Proposed techniques include lymphaticovenous anastomosis (LVA), vascularized lymph nodes transfer (VLNT), and suction lipectomy (SL). The benefit of combined procedures has also been postulated. In this prospective study, a combined protocol is proposed as an alternative to single-procedure strategies.

METHODS

Between January 2016 and October 2018, we enrolled patients with secondary lymphedema of lower limbs, stage II-III according to the International Society of Lymphology, progressive swelling and skin tonicity >60. Thirty-seven consecutive patients were dichotomized into group I, undergoing VLNT, and group II undergoing VLNT and LVA. Gastroepiploic lymphnode flap was harvested through laparoscopy, and in the same operation, LVAs were performed in group II on the basis of indocyanine green lymphography and patent blue findings. Two weeks later, SL was performed in all the patients. Patients were prospectively evaluated through clinical examination, circumference measurement, and skin tonicity.

RESULTS

The average follow-up was 2 ± 0.8 years. The first consecutive 21 patients were treated with VLNT followed by SL. The next 16 patients underwent combined VLNT and LVA, followed by SL. A mean of 2.4 LVAs were performed. A significant difference in the postoperative circumference measurements was found overall (p < .05): 52.6 ± 18.9 above the knee, 42.9 ± 25 below the knee, 36.2 ± 37 at foot. The postoperative tonicity dropped by 12.7 ± 6.3% (p < .05). The episodes of cellulitis significantly decreased to 0.1 ± 0.3 (p < .05).

CONCLUSIONS

LVA, VLNT, and SL can be integrated together in a combined approach, in synergy to enhance the outcomes.

Meta-analysis of prepectoral implant-based breast reconstruction: guide to patient selection and current outcomes

PURPOSE

 This meta-analysis provides a large-scale comparison of prepectoral vs. subpectoral implant-based breast reconstruction, with primary outcomes of patient safety and efficacy.

METHODS

Literature review was performed via PRISMA criteria, 33 studies met inclusion criteria for prepectoral review and 13 studies met inclusion criteria for meta-analysis. Patient characteristics and per-breast complications were collected. Data were analyzed using Cochrane RevMan and IBM SPSS.

RESULTS

In 4692 breasts of 3014 patients that underwent prepectoral breast reconstruction, rippling was observed as the most common complication, followed by seroma and skin flap necrosis. Meta-analysis demonstrated statistically significant decrease in odds of skin flap necrosis and capsular contracture in prepectoral groups compared to subpectoral groups. Odds of infection, seroma, and hematoma were equal between the two groups.

CONCLUSIONS

Prepectoral breast reconstruction has surged in popularity in recent years. This review and large-scale analysis corroborates current literature reporting a favorable safety profile with emphasis on patient selection. Variability in skin flap thickness and vascularity mandates thoughtful selection of patients whose overall health and intra-operative skin flap assessment can tolerate a muscle-sparing reconstruction.

[New surgical strategy in breast reconstruction with implants for bilateral prophylactic mastectomies with BRCA gene mutation]

BACKGROUND

For the past decades, number of prophylactic bilateral mastectomies using reconstruction with implants increases. We describe a new surgical strategy and analyse its safety and feasability.

METHOD

It is a retrospective, descriptive and monocentric study. The first step of surgery consisted in obteining a peri-prosthetic capsule with implants and if there was a mammary hypertrophy and/or ptosis, it was corrected at the same time. The second step of surgery was the nipple-sparing mastectomy with change of implants for bigger ones. Third step consisted in a lipofilling.

RESULTS

Seven patients were included. 6 women had a BRCA1 gene mutation. Mean age was 35.6 year-old [29.6; 41.6], mean BMI was 23.8kg/m² [20.6; 27], mean chest circumference was 93.7cm [87.4; 100], mean cup was C- [B-; D-]. 4 women had mammary hypertrophy and/or ptosis. Mean number of procedure per woman was 3.6 [2.5; 4.7]. Mean volume of implants used at the first step was 248.6ml [211.3; 285.9]. The second step was performed mean 33.9 weeks [22.3; 45.5] later. Mean increase of implants volume was 120ml [80.4; 159.6]. 4 patients had complications including 1 who had implant exposure. Six patients had lipofilling of mean volume per breast of 175ml [116; 234].

CONCLUSION

This new strategy could decrease complication rate, improve aesthetic outcome and decrease psychological impact of surgery.

The New Trend of Pre-pectoral Breast Reconstruction: An Objective Evaluation of the Quality of Online Information for Patients Undergoing Breast Reconstruction

The Web has increasingly become the major source of information about health care, and patients who need to undergo breast reconstruction often use the internet to acquire an initial knowledge on the subject. We would like to present our study that investigates the quality of published information on pre-pectoral breast reconstruction. We searched the term "Pre-pectoral breast reconstruction" on Google^® and Yahoo^®. Forty-two web sites were selected and underwent qualitative and quantitative assessment using the expanded EQIP tool. The analysis of document contents showed a critical lack of information about qualitative risks and side-effects descriptions, treatment of potential complications, alert signs for the patient and precautions that the patient may take. Health professionals should inform patients about the potential difficulties of identifying reliable informational web sites about pre-pectoral breast reconstruction. The quality of available information should be improved, especially the important topics included in the content data section of the modified EQIP tool.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Comparison of prepectoral and subpectoral breast reconstruction after mastectomies: A systematic review and meta analysis

BACKGROUND

The safety of prepectoral breast reconstruction (PBR) after mastectomies as compared to subpectoral breast reconstruction (SBR) were unclear, so we conducted a systematic review to analyze their differences.

METHODS

PubMed, EMBASE, the Cochrane Library, and Web of Science databases were searched to retrieve studies that compared PBR with SBR after mastectomies. The outcomes were complications, oncological safety, patient-reported outcomes and postoperative pain. Revman software version 5.30 and stata vesion 12 was used to conduct meta-analysis where possible.

RESULTS

16 comparative studies (12 articles and four abstracts) were included. The meta analysis showed no statistical differences in overall complications, implant loss, seroma, nipple or skin flap necrosis, hematoma, reoperation, wound dehiscence, and wound-skin infection, rippling between PBR and SBR. PBR might be associated with fewer nipple or skin flap necrosis for those who received tissue expander placement, and fewer capsular contracture rates for those who received implant. PBR might be associated with better Breast Q scores and less postoperative pain without increasing the risk of local recurrence and metastatic disease.

CONCLUSION

Although available evidence is limited, PBR might be as safe as subpectoral approach. Future well designed multicenter randomized controlled trial that compare postmastectomy PBR with SBR is needed.
