ESP Blocks in Breast Free Flaps

This study is a prospective randomized controlled trial to assess the efficacy of erector spinae plane (ESP) blocks in patients undergoing autologous free flap breast reconstruction. Currently, patients undergoing this procedure remain in the hospital initially for flap monitoring until discharge criteria is met, when pain is adequately controlled and patient is able to ambulate independently. Prolonged hospital stays can occur due to persistent pain, typically abdominal pain as breasts are insensate following mastectomy. Persistent pain at abdominal incision can increase opioid requirements, impede ambulation trials, and delay discharge. This study aims to utilize ESP blocks to help augment pain control in patients undergoing autologous free flap breast reconstruction. The ESP block is a safe regional block that is already commonly utilized by multiple surgical specialties, such as general surgery, obstetrics and gynecology, cardiothoracic surgery, neurosurgery, and orthopedic surgery. The ESP block is an ultrasound-guided regional anesthesia technique where a local anesthetic is injected into the fascial plane between the erector spinae muscles and the thoracic vertebrae's transverse processes. This injection spreads longitudinally, blocking the spinal nerves and providing multi-dermatomal pain relief to the anterior, posterior, and lateral chest and abdominal walls, making it useful for surgeries and managing chronic pain. Patients in this study will be randomized into one of two groups, ESP block or No ESP (NESP) block group. The investigators will not be blinding patients to their study arm assignment, as this would require injecting placebo which the investigators believe would be an unnecessary risk to patient. Additionally, it was determined that it would not be feasible to blind patients as the ESP block participants would be numb in their abdomen and patients would immediately know whether or not they received the block. Participants will be informed of their study arm assignment on the day of surgery prior to proceeding to the operating room. Patients will then be asked to fill out a twice daily survey on pain and ambulation trials. Inpatient data on pain medication administration and time to discharge will be collected through chart review. This study aims to investigate the efficacy of ESP blocks to improve management of pain at abdominal incision, decrease inpatient opioid consumption, decrease time to ambulation, and decrease length of stay.

Abdominal Scar Improvement in Microsurgical Breast Reconstruction

Microsurgical breast reconstruction is most commonly performed with free abdominal flaps, which leave a long transverse lower abdominal scar. Due to tension across the incision, these scars frequently widen and hypertrophy. Hence, modalities that can reduce this tendency, thus, improving scar appearance are desirable. Here, we wish to investigate the impact of the Neodyne embrace device on postoperative abdominal scar appearance. The proposed study is novel in that it is the first RCT investigating the effect of the embrace device on scar appearance in the context of microsurgical breast reconstruction.

Evaluation of the Impact of Pre-habilitation Using Physiotherapy and Mechanical Stimulation on Shoulder Pain and Mobility in Patients Undergoing Breast Reconstruction Using a Latissimus Dorsi Flap

Each year in France, nearly 59,000 new cases of breast cancer are diagnosed, and approximately 22,000 mastectomies are performed. Among these patients, 30% choose to undergo breast reconstruction. Breast cancer leads to numerous physical and psychological changes. The need to strengthen patient support around breast reconstruction has been highlighted, and it is one of the priorities of the national Ten-Year Cancer Control Strategy. The growing number of patients living after cancer makes the management of post-treatment sequelae essential. The rate of reconstruction is increasing thanks to improvements in technique and better access to information. Among the available options, the latissimus dorsi (LD) flap has been a standard technique for immediate and delayed breast reconstruction for over 25 years. The LD technique offers several advantages: high reliability, feasibility even in irradiated thoraxes, low rates of postoperative complications, and satisfactory aesthetic outcomes. Its versatility and reliability have made it a cornerstone of breast surgery. However, this technique can lead to short- and long-term functional sequelae, which persist in 10% of patients. To reduce these side effects, an optimized version-the lipofilled mini-latissimus dorsi flap (mLD)-was developed by a team in Strasbourg. This quicker and less muscle-invasive technique is mainly used for immediate reconstruction or to replace implant-based reconstruction, with systematic lipofilling. However, no objective functional assessment of this method has yet been carried out, justifying a stratification according to the type of procedure for randomization in future studies. According to a prospective Icelandic study involving 15 patients, full recovery can be expected, but patients must be informed of the time and effort required to achieve it. The authors also concluded that further research is necessary to better understand the limits of long-term recovery. A study of 450 LD reconstructions showed that pain and the main functional sequelae were located in the back and shoulder, with 10% of patients experiencing significant long-term pain. In addition, according to this study, around 40% of patients consider postoperative sequelae and scarring burdensome. However, regret rates remain low, at under 3%. In view of these findings, preventing pain and functional impairment has become a key research focus to improve patients' quality of life. Postoperative rehabilitation plays a crucial role in managing pain, reducing functional impairment, and optimizing aesthetic outcomes. The addition of mechanostimulation (MS) has been shown to improve scar appearance, shoulder function, and functional well-being compared with rehabilitation alone. MS is delivered using a device equipped with motorized rollers and suction to mobilize tissues. In physiotherapy, it helps relieve pain and improve mobility. Prehabilitation, a rapidly expanding concept in surgery, aims to prepare patients before their procedure. However, to date, no prehabilitation approach combining physiotherapy and MS has been considered prior to LD flap surgery. One study highlighted improved tissue trophicity after tissue preparation with MS before lipomodelling. The objective of our study is to evaluate the benefit of prehabilitation through physiotherapy incorporating MS to prepare tissues (in particular skin and muscle) on shoulder pain and functional outcomes in patients undergoing breast reconstruction with a latissimus dorsi flap. Additionally, due to the heterogeneity and sometimes limited access to specialized postoperative physiotherapy, extensive patient follow-up has been planned in order to describe, on an exploratory basis, real-world rehabilitation practices.

The study will assess the effects of the formulation on skin elasticity, hydration, and overall appearance when used as part of post-procedure care under the supervision of licensed medical professionals. Participants will apply the product to treatment areas over a defined study period, and outcomes will be compared to a control group receiving standard care or placebo.

Immediate Autologous Tissue Breast Reconstruction and Radiotherapy Strategy After Breast Cancer Surgery

This is a prospective, open-label, controlled clinical trial aiming to investigate the optimal sequencing strategy between immediate autologous tissue breast reconstruction and radiotherapy in breast cancer patients. Eligible participants are female breast cancer patients who have completed neoadjuvant chemotherapy and are scheduled to undergo total mastectomy combined with immediate free abdominal flap (DIEP) breast reconstruction. Participants will be assigned to receive either preoperative radiotherapy followed by reconstruction, or postoperative adjuvant radiotherapy after reconstruction. The primary objectives are to compare surgical safety, oncological safety, patient-reported outcomes (PRO), and aesthetic evaluation between the two radiotherapy sequencing strategies. Secondary objectives include optimizing radiotherapy techniques, radiation doses, and target volume delineation for immediate abdominal free flap reconstruction; exploring the impact of hypofractionated radiotherapy on reconstruction-related complications; investigating the association between multi-omics and immune microenvironment changes and radiotherapy efficacy; and exploring the mechanism by which skin microbiota characteristics affect radiation-induced skin injury through modulation of the skin immune microenvironment. This study hopes to provide clinical evidence for establishing the optimal treatment sequence of immediate breast reconstruction and radiotherapy.

Autologous Fat Grafting for Total Breast Reconstruction in Irradiated Breast Cancer Patients

The goal of this clinical trial is to learn whether autologous fat transfer (AFT) is as effective and safe as Deep Inferior Epigastric Perforator (DIEP) flap breast reconstruction in irradiated breast cancer patients following mastectomy. It will also evaluate patient satisfaction, quality of life, complication rates, and cost-effectiveness of both reconstruction techniques. The main questions it aims to answer are: Does AFT result in non-inferior patient satisfaction with the reconstructed breast compared to DIEP flap reconstruction 12 months after the final operation? Does AFT result in fewer major complications and improved cost-effectiveness compared to DIEP flap reconstruction? Are quality of life outcomes and oncologic safety comparable between AFT and DIEP flap reconstruction in irradiated patients? Researchers will compare AFT to DIEP flap reconstruction to see if AFT can provide similar reconstructive outcomes with lower morbidity and fewer complications in irradiated breast cancer patients. Participants will: Undergo breast reconstruction using either AFT or DIEP flap reconstruction Attend follow-up visits for clinical examinations, imaging, and assessment of complications Complete questionnaires about breast satisfaction, quality of life, and recovery during follow-up Be monitored for oncologic safety and reconstructive outcomes for 12 months after the final operation

DIEP-MDS for Risk Stratification of Flap Vascular Compromise and Failure in Breast Reconstruction

This multicenter retrospective observational study will develop and validate a CTA-based quantitative risk score-the DIEP Morphological Deviation Score (DIEP-MDS)-to estimate the risk of flap-related vascular compromise and flap failure in patients undergoing DIEP flap breast reconstruction. The score will quantify the extent to which an individual's perforator anatomy deviates from normative anatomic distributions derived from a reference population of individuals without breast cancer or reconstructive surgery. Specifically, a cohort of randomly selected individuals with available CTA imaging will be used to establish population-level reference distributions for key anatomic features relevant to DIEP perforator morphology, including length, diameter, and muscle thickness. The study will determine whether greater deviation in DIEP morphology, as quantified by the DIEP-MDS, is associated with an increased risk of flap-related vascular compromise and flap failure. The score will be evaluated in an internal surgical cohort and externally validated in an independent multicenter surgical cohort. In addition, the study will pre-specify an analysis to assess whether a dual-pedicle strategy is associated with a lower risk of flap-related vascular compromise compared with a single-pedicle strategy across DIEP-MDS risk strata.

EndoBreast Study - Assessment of Feasibility, Functional Outcomes, and Sensitivity of the Areola-Nipple Complex in Endoscopic Mastectomy

Study Design Prospective, single-center, observational, non-interventional study conducted in routine clinical practice. No investigational treatments or modifications to standard diagnostic, therapeutic, or follow-up procedures are planned. Consecutive eligible patients undergoing endoscopic nipple-sparing mastectomy (NSM) with immediate breast reconstruction will be prospectively enrolled. Background and Rationale Nipple-sparing mastectomy with immediate reconstruction is an established treatment for selected patients with breast cancer and women undergoing prophylactic mastectomy because of hereditary risk. Preservation of the nipple-areola complex (NAC) improves cosmetic outcomes, body image, and patient satisfaction while maintaining oncological safety. Endoscopic NSM is a minimally invasive alternative that may reduce scarring, surgical trauma, and recovery time while improving aesthetic outcomes without compromising oncological radicality. However, evidence remains limited, particularly in Europe, regarding feasibility, perioperative safety, sensory recovery, quality of life, reconstructive outcomes, and long-term oncological results. This study aims to prospectively collect real-world data from a consecutive cohort treated at a specialized breast center. Primary Objective To evaluate the feasibility and surgical safety of endoscopic NSM with immediate breast reconstruction in patients undergoing prophylactic or therapeutic mastectomy. Secondary Objectives To evaluate NAC sensory recovery at 6 and 12 months; assess oncological safety through surgical radicality and follow-up; evaluate quality of life and patient satisfaction using validated questionnaires; describe disease-free survival (DFS), overall survival (OS), reconstructive and aesthetic outcomes; and assess postoperative hospital stay. Primary Endpoints Overall incidence of early surgical complications; incidence of NAC necrosis, skin flap necrosis, infection, seroma, hematoma, hospital readmission, reoperation, and implant loss; recovery of NAC sensation at 6 and 12 months; and pathological assessment of retroareolar margin status. Secondary Endpoints BREAST-Q scores; local, regional, and distant recurrence; DFS; OS; and reconstructive/aesthetic outcomes. Study Population and Sample Size Thirty consecutive adult women undergoing prophylactic or therapeutic NSM with immediate implant-based reconstruction according to multidisciplinary evaluation. Main Inclusion Criteria Female; age 18-75 years; indication for prophylactic or therapeutic NSM; breast volume suitable for endoscopic surgery; Regnault ptosis ≤ Grade II; eligibility for immediate implant-based reconstruction; WHO/ECOG performance status \<3; written informed consent.

Immediate prepectoral implant-based reconstruction will follow. Data Collection and Follow-up Clinical, surgical, pathological, perioperative, and follow-up data will be prospectively recorded in a dedicated electronic Case Report Form. Patient-reported outcomes will be assessed using the validated BREAST-Q Reconstruction Module. Assessments will be performed preoperatively, intraoperatively, at 30 and 60 days, 6 months, 12 months, and annually up to 5 years. BREAST-Q will be administered at 6 months, 12 months, and annually thereafter. Study Duration Enrollment will continue until 30 patients have been recruited. Each participant will be followed for 5 years. Statistical Analysis This descriptive exploratory study will summarize categorical variables as frequencies and percentages and continuous variables using appropriate descriptive statistics. Long-term oncological outcomes will be reported as observed events, with DFS and OS estimated using Kaplan-Meier analysis when appropriate. Ethics The study is observational and does not alter routine clinical management. No additional significant risks beyond standard surgical care are anticipated. Written informed consent is mandatory. Personal data will be pseudonymized and processed in accordance with the General Data Protection Regulation (EU 2016/679) and applicable national legislation. Expected Benefits and Risks The study will provide prospective evidence on the feasibility, safety, functional recovery, quality of life, reconstructive outcomes, and oncological effectiveness of endoscopic NSM.

Assessment of Topical Minoxidil on Intraoperative Flap Perfusion and Cutaneous Flap Viability in Breast Recon

The purpose of the study is to determine whether pharmacologic delay using minoxidil in patients undergoing bilateral risk reducing mastectomy with reconstruction could achieve improvement in flap perfusion and flap viability at the time of surgery. Patients will undergo randomization of their breasts to determine which breast will receive the experimental intervention and which breast will serve as the internal control (receive placebo). The experimental breast will receive the novel pharmacologic delay treatment, 5% minoxidil, while the internal control breast will receive the current standard of care, which does not include any topical application prior to surgery - a placebo control will be used. This will be a triple-blind study, where both the participants and investigators will be blinded to which breast will receive the intervention. The patients will receive two bottles "compound A" and "compound B" with directions from the pharmacy for which compound to apply to each breast. Product will be applied for 2 weeks prior to planned surgery. Surgery will proceed without any changes to standard practice.

NIR Device for Assessment of Skin Flap Perfusion in Breast Surgery: A Pilot Interventional Study

The goal of this single-center, nonrandomized, interventional non-profit pilot study is to evaluate the feasibility and clinical utility of a non-invasive near-infrared spectroscopy (NIRS) imaging device for assessing skin-flap tissue oxygen saturation in adult women undergoing mastectomy and immediate breast reconstruction after oncological surgery. The main questions it aims to answer are: * Can NIRS imaging provide reproducible measurements of tissue oxygen saturation (StO₂) in mastectomy skin flaps before surgery, during the intraoperative phase, and during postoperative follow-up? * Can spatial and temporal variations in StO₂ identify areas of potentially reduced flap perfusion or impaired tissue viability? * Can NIRS-derived oxygenation measurements support the assessment of postoperative flap healing and ischemic complications? Participants will: * undergo non-invasive NIRS imaging of the breast skin flap before surgery; * undergo one intraoperative NIRS acquisition during mastectomy and immediate breast reconstruction; * undergo repeated NIRS imaging during postoperative follow-up visits; * receive standard surgical treatment and postoperative care according to routine clinical practice. NIRS imaging is performed for study purposes and does not influence intraoperative surgical decision-making or the choice of reconstructive procedure.

ORASIS in Breast Reconstruction

The purpose of this study is to assess the use of ORASIS during microsurgical anastomosis formation in Deep Inferior Epigastric Perforator (DIEP) flap breast reconstruction and its potential effects on surgical precision, surgeon efficiency, and anastomosis outcomes. The investigators hypothesize that the use of ORASIS will decrease the amount of time needed to perform microsurgical anastomoses, reduce interruptions for irrigation and suction, and increase the quality of anastomoses in DIEP flap breast reconstruction.

Post-market Prospective Clinical Study of Nagor Perle Mammary Implants

Patients can undergo breast implant surgery for multiple reasons; cosmetic and reconstructive being the primary indications. In order to confidently state safety and due to strict regulation on medical devices it is important to maintain a record of safety and performance with all medical implants. This study is designed to collect data on a new generation of smooth mammary implants to assess the long term performance and safety data on this type of gel-filled mammary breast implant. The two main complications of breast implants are capsular contracture and rupture; these complications can take years to develop. The study is designed to evaluate the occurrence of these two primary complication as well as other secondary complications over a period of 10 years. Patient follow up will be carried out pre-operatively and post operatively at 12 months and then 3, 5, 8 and 10 years thereafter. The study will be carried out over 10 years to adequately assess complications which may only occur over the lifetime of the device such as systemic complications
