Investigation of the Effects of Serratus Posterior Superior Intercostal Plane Block and Serratus Anterior Plane Block on Perioperative Analgesia Management in Patients Scheduled for Mastectomy

This study aims to evaluate and compare the analgesic efficacy of two ultrasound-guided regional anesthesia techniques, the serratus anterior plane (SAP) block and the serratus posterior superior intercostal plane (SPSIP) block, in patients undergoing elective mastectomy surgery. Postoperative pain following mastectomy is a common and significant clinical problem that negatively affects patient comfort, delays mobilization, and may prolong hospital stay. Although systemic analgesics are commonly used, they are associated with adverse effects such as sedation, constipation, and potential dependency. In this randomized clinical study, female patients aged 18-75 years with ASA physical status I-III scheduled for elective mastectomy will be included after obtaining informed consent. Patients will be allocated into two groups to receive either SAP block or SPSIP block under ultrasound guidance prior to surgery. Standardized general anesthesia and perioperative analgesia protocols will be applied to all patients. The primary objective is to compare postoperative pain scores between the two groups using the Numeric Rating Scale (NRS). Secondary outcomes include time to first analgesic requirement, total analgesic consumption, intraoperative opioid use, and hemodynamic parameters. By comparing these two interfascial plane blocks, this study aims to identify a more effective analgesic technique that improves postoperative pain control, enhances patient comfort, and facilitates early mobilization following mastectomy.

Same-Day Awake Mastectomy With Immediate Breast Reconstruction for Patients With Breast Cancer

The goal of this clinical trial is to learn if the AMADeuS care pathway is as safe as usual hospital care and works as well for pain control in women having mastectomy with immediate prepectoral breast reconstruction. The study will also look at quality of life, satisfaction with care, hospital resource use, and environmental impact. The main questions it aims to answer are: 1. Does the AMADeuS pathway control pain during the first 48 hours after surgery as well as usual hospital care? 2. Is the AMADeuS pathway as safe as usual hospital care during the first 30 days after surgery? 3. Can the AMADeuS pathway improve recovery, reduce hospital stay and hospital visits, and lower the environmental impact of care? Researchers will compare the AMADeuS pathway with usual hospital care. In the AMADeuS pathway, participants will have awake surgery with monitored anesthesia care, same-day discharge when safe, and follow-up that includes telemedicine. In the usual care group, participants will receive the hospital's standard perioperative care, which usually includes admission to the ward and follow-up visits at the hospital. Participants may be women 18 to 75 years old who need nipple-sparing or skin-sparing mastectomy with immediate prepectoral reconstruction for early breast cancer or to lower future breast cancer risk. Participants must be suitable for day surgery and telemedicine follow-up. This includes having home support during the first 24 hours after surgery and living close enough to the hospital for safe discharge. Participants will: * be assigned by chance to the AMADeuS pathway or to usual hospital care have mastectomy with immediate prepectoral reconstruction report their pain during the first 48 hours after surgery * be checked for medical problems during the first 30 days after surgery complete questionnaires about quality of life, symptoms, and satisfaction with care during follow-up * have follow-up visits either through telemedicine and planned local care support or through standard hospital follow-up, depending on the group they are assigned to

A Study on Pain After Breast Reconstruction

The purpose of this study is to find out how common persistent postmastectomy pain (PPMP) is among people who have had a mastectomy and breast reconstruction surgery for their breast cancer. The study will also look at how effective regenerative peripheral nerve interface (RPNI) surgery is for reducing pain from neuropathic PPMP after breast reconstruction.

Long-term Outcomes of Lidocaine Infusions for Post-Operative Pain (LOLIPOP) Trial

Biological and Clinical Underpinnings of Postoperative Pain - Mastectomy

Persistent pain after mastectomy remains a significant clinical challenge that can delay recovery, reduce quality of life, and increase long-term healthcare burden. The goal of this study is to gain a deeper understanding of the biological and clinical factors that influence pain severity after mastectomy and contribute to the transition from acute to chronic postoperative pain. Guided by a biopsychosocial framework, this research will address the following aims: 1. We will use standardized experimental pain testing before surgery to evaluate how patients respond to different types of controlled sensory stimuli. These responses may help predict who is more likely to experience severe or prolonged pain after surgery. 2. We will analyze blood samples collected before and after surgery to measure markers of inflammation and other biological responses. These data will help us explore how the body's immune and hormonal systems relate to pain severity in both the short- and longer-term recovery phases. 3. We will assess psychological and clinical factors, such as emotional health, coping style, household income, and life stressors, to understand how they contribute to patients' pain experiences throughout recovery. 4. We will examine whether routinely collected demographic and clinical characteristics can help identify patients at greater risk of experiencing higher levels of pain after surgery. This approach will allow us to better understand which patients may benefit from more tailored perioperative pain management strategies.

A Prospective Study of Video-assisted Exercise Program for the Breast Cancer Survivors

The investigators cancer rehabilitation/recovery program, Strong Survivor, has been designed to be delivered digitally, and while there are many such programs currently available on the internet, especially in the time of COVID-19, the novel feature of this program is the delivery of semi-individualized instruction in real time within a small group setting. The program was designed with physician input and by exercise physiologists and a Doctor of Physical Therapy candidate, all with extensive training in both group and individualized exercise for geriatric and cancer survivor populations. Strong Survivor is 16-week iterative curricular program with three core components: aerobic fitness, balance and mobility, and muscular strength and power. Classes will be held twice per week. The first 4 classes will be deployed in a small class of up to 5 people (first 2 weeks), then one class per week with the small class and one class per week is with a larger class of up to 15 people (weeks 3 and 4). The program is then continued for 12 additional weeks in a larger class using principles and exercises specifically trained during the small group classes. All the exercises offered over the course of the intervention are appropriate for the target population and are standardized so all participants receive the same basic instruction, but level of difficulty is scaled to participant experience, capability, and musculoskeletal limitations. Participants will need to have a minimal adequate space and technology to accommodate this instructional method. Specifically, they will require an internet connected device with a camera that is at least 7 inches square. (tablet size or larger). Additionally, participants' will need to have adequate space to both set up a computer/camera and move around. The minimal acceptable space for this is 6+ feet with an unobstructed view (from a table for instance) of a 2 x 2 open space. All study participants will complete a clinic visit before they join the classes and after the last class to evaluate cardiorespiratory fitness, strength, balance and posture and answer questionnaires about quality of life and system usability.

Finding Sentinel Lymph Nodes During Mastectomy Using Indocyanine Green (INIGMA Study)

This pilot study evaluates the diagnostic value of indocyanine green (ICG) fluorescence for sentinel lymph node biopsy (SLNB) performed through the mastectomy incision in breast cancer patients. Women with clinically node-negative, invasive T1-T3 breast cancer undergoing mastectomy with SLNB at St. Antonius or Isala Hospital will be included. All patients receive standard 99mTc injection preoperatively, followed by 5 mg (2mL) ICG injection after anesthesia. The axilla will be explored for fluorescent lymph nodes via the mastectomy incision, avoiding a separate axillary incision. Primary outcome: ICG detection rate for SLN identification via the mastectomy incision. Secondary outcomes: Comparison with 99mTc detection, number of nodes identified, concordance between methods, pathology differences, detection time, and complications. ICG is safe, non-ionizing, and causes no extra discomfort or visits. Risks and burden are minimal.

Evaluating the Efficacy of Force Modulating Tissue Bridge Device in Preventing Hypertrophic Scars Following Gender-Affirming Mastectomy

The goal of this randomized, prospective, interventional clinical trial is to evaluate the use of Brijjit® in reducing the incidence of hypertrophic scarring in individuals undergoing gender-affirming bilateral double incision mastectomies at a single-institution, single-surgeon site (Esther A. Kim, MD). Patients will serve as a self-control (one side of the chest receives intervention, the other serves as a control). Primary endpoints include scar appearance and quality. Secondary endpoints include patient perception of the scar using the Patient and Observer Scar Assessment Scale (POSAS). Participants will be taught how to apply Brijjit® at home if any units fall off before 6 weeks postop.

A Study to Reduce Persistent Post-mastectomy Pain Using Opioid-free Anesthesia

In 230 patients undergoing mastectomy, the investigators will compare opioid-free anesthesia (OFA) versus conventional opioid-based anesthesia in terms of chronic pain. The enrolled patients will be randomly assigned into two groups with 1:1 ratio. Chronic pain will be evaluated at 1 year after mastectomy based on the Breast Cancer Pain Questionnaire (BCPQ). Baseline pain sensitivity test and psychologic evaluation will be done before operation.

Assessment of the Interi Manifold in Implant-Based Breast Reconstruction

Patients with breast cancer that elect to undergo implant-based breast reconstruction (IBBR) often require the placement of a surgical drain. Surgical drains are used to manage dead space and prevent seroma formation or accumulation of fluid within the surgical field postoperatively. The most frequently used drain is a Jackson-Pratt (JP) drain, which is limited by poor surgical site coverage and low capacity, leading to inconsistent suction and prolonged time that a drain is left in place. The Interi Drain system is a novel, multi-branched manifold with a proprietary suction system that provides consistent suction and addresses many of the shortcoming of JP drains. The purpose of this study is to compare the Interi system to standard JP drains across outcomes including number of surgical drain sites, complication rates, time to drain removal, time to initiate tissue expansion, total fluid volume drained, and patient satisfaction.

The Role of Amnion Membrane Allografts in Nipple Preservation

The overall objective of this proposal is to conduct a randomized-controlled study to determine whether treatment with dehydrated human amnion/chorion membrane (dHACMs) allografts can improve NAC viability in patients undergoing nipple sparing mastectomy (NSM). dHACM allografts are commercially available tissue membranes with biocompatible extracellular matrix and growth factors that have been shown to improve wound healing in patients with chronic and lower extremity wounds. To date, no study has evaluated the impact of dHACMs on NAC preservation following NSM. Investigators hypothesize that subareolar surgical implantation of dHACM allografts at time of NSM will reduce NAC necrosis and improve viability.

Interactive Design of Patient-Specific Molds for Tissue Shaping

The goal of this study is to develop clinical decision-support algorithms for designing participants-specific breast molds for tissue shaping. Autologous breast reconstruction is an important part of breast cancer rehabilitation for many participants. Our goal is to increase the efficiency of autologous breast reconstruction by helping the surgeon design participants-specific molds for shaping tissue into an acceptable breast form.

A Bionic Breast Project Using Neuroprosthesis to Reduce Chronic Pain After Mastectomy

This trial seeks to establish whether or not touch sensation can be restored to the breast via neural stimulation. Data will also be obtained to inform future feasibility (including safety), efficacy, and acceptability trials.

Impact of Erector Spinae Plane Block on Chronic Postsurgical Pain in Breast Cancer Patients

Chronic postsurgical pain (CPSP) has an incidence of 46% in patients after breast cancer surgery, which seriously affects patients' physiological and psychological function, as well as quality of life. Acute pain is an independent risk factor for persistent pain after surgery. Erector spinae plane block (ESPB) provided excellent perioperative analgesia in patients undergoing breast surgery. Dexmedetomidine as an adjuvant of local anesthetics prolongs the duration of peripheral nerve block and decreases the requirements of postoperative analgesia. The investigators hypothesize that, for breast cancer patients undergoing mastectomy, ESPB (with a combination of 0.5% ropivacaine 35 ml and dexmedetomidine 1 microgram/kg) can reduce the occurrence of CPSP. The purpose of this randomized controlled trial is to investigate the impact of ESPB with adjuvant dexmedetomidine on the incidence of CPSP in breast cancer patients after mastectomy. We will also observe the impact of ESPB on long-term survival in these patients.

A Comparative Analysis of REVOLVE, LipoGrafter, and Viality in Autologous Fat Grafting During Breast Surgery

Effect of Kinetic Control Exercise on Shoulder Dysfunction Post Mastectomy

The purpose of this study is to evaluate the effect of kinetic control exercises on shoulder dysfunction in post-mastectomy.

Impact of Nipple Reconstruction in Mastectomized Patients Using Cross-Linked Hyaluronic Acid Injection.

This study evaluates the impact of hyaluronic acid (HA) injection for nipple projection following mastectomy, as a complement to areola micropigmentation. While micropigmentation is standard in nipple-areola complex (NAC) reconstruction, HA use remains novel, with limited data on psychosocial, sexual, and aesthetic outcomes. A sequential explanatory mixed-methods design will be used. In Phase 1, a randomized controlled trial will compare two groups: one receiving NAC micropigmentation alone (control) and the other receiving micropigmentation plus HA-based nipple projection (intervention). A total of 138 participants will be recruited at the Areolar Micropigmentation Unit of Germans Trias i Pujol University Hospital (Barcelona) over 36 months. Outcomes will include psychosocial and sexual well-being, satisfaction with breast and nipple appearance, and nipple projection, measured using the Spanish BREAST-Q, a custom satisfaction tool, and calipers. Phase 2 will involve a qualitative phenomenological study using semi-structured interviews with a purposive sample from the intervention group. Thematic analysis will explore body image, emotional and social well-being, and overall satisfaction, using NVivo software. This is the first study assessing HA nipple reconstruction by advanced practice nurses using validated patient-reported outcomes. While the BREAST-Q is appropriate, it may not fully capture emotional nuances, justifying qualitative exploration. HA durability is estimated at 6-9 months, but residual volume and satisfaction over time remain underexplored. HA's aesthetic footprint may allow reduced dosages in future applications. This minimally invasive technique may reduce the need for surgical nipple reconstruction. Conducting the procedure in a nurse-led setting is novel and may enhance patient-centered care and the role of nursing in post-mastectomy recovery. The study complies with the Declaration of Helsinki and Spanish biomedical regulations. Ethical approval was obtained. Participants will provide informed consent, and data will be anonymized and securely stored.

Compassion, Social Support, Flexibility, and Resilience Program for Women Surviving Breast Cancer

The goal of this clinical trial is to investigate the effects of an Acceptance and Commitment Therapy (ACT) based program (ReACT) to increase social support, compassion and psychological flexibility on psychological resilience in women undergoing mastectomy. The main question it aims to answer is: Does the ReACT program improve participants' resilience by increasing social support, compassion, and psychological flexibility? Researchers will compare intervention group to control group to see if ReACT program works to improve participants' resilience. Researchers will randomly divide participants into two groups: intervention group and control group. * Participants will complete some questionnaires. * Participants in the intervention group will join a 3-week ACT-based psychological flexibility program. This program consists of sessions that last 90 minutes each. The program adopts the core principles of ACT and aims to help participants develop skills in mindfulness, acceptance, value-driven living, and cognitive defusion. * Participants will complete the same questionnaires again after the program. * Participants will complete the same questionnaires again 1 month after the program ends.

Dexmedetomidine Versus Lidocaine Infusions as Adjuvants to General Anesthesia for Chronic Pain Management After Mastectomy

This study aims to compare dexmedetomidine and lidocaine infusions as adjuvants to general anesthesia for chronic pain management after mastectomy.

Preoperative vs. Pathologic Size in Breast Cancer: A Prospective Study

Breast cancer, the most prevalent malignancy among women globally, is increasing in incidence. While non-metastatic breast cancer requires surgery, determining the optimal extent of resection remains challenging. Inadequate resection margins necessitate reoperation, leading to increased psychological stress, costs, and potentially compromised cosmetic outcomes and prognosis. Accurate preoperative assessment of resection extent is crucial and involves various factors, including imaging studies, physical examinations, tumor molecular subtypes, and intraductal carcinoma components. This prospective observational study aims to identify and integrate multiple predictive factors to enhance surgical planning and minimize reoperation rates in breast cancer patients.

Seroma of the Mammary Gland
