Is Immediate Breast Reconstruction With a Latissimus Dorsi Myocutaneous Flap Safe for Starting Adjuvant Chemotherapy in Patients With Breast Cancer?

INTRODUCTION: Immediate breast reconstruction following mastectomy reduces perceptions of mutilation and femininity issues in oncological patients, but surgical complications should not delay chemotherapy. This study evaluated postsurgical complications in patients who underwent radical breast surgery followed by immediate reconstruction with latissimus dorsi myocutaneous flaps and silicone implants, along with resulting impacts in delaying chemotherapy. MATERIALS AND METHODS: This retrospective study utilized a prospectively maintained database. Clinical, surgical, and oncological data from 196 women were collected according to the operated side. Patients were grouped according to the time elapsed between surgery and the first cycle of adjuvant chemotherapy: ≤ 60 days (group 1), 61 to 90 days (group 2), or > 90 days (group 3). RESULTS: A total of 198 immediate reconstructions were performed on 196 patients between August 1, 2010 and March 31, 2020; after surgery, 47.4% had minor complications and 7.1% had major complications. Ninety-six patients (48.5%) received adjuvant chemotherapy. The mean time elapsed between surgery and the first chemotherapy cycle was 65.4 days (median: 59), with 52.7% of the patients assigned to group 1, 37.4% to group 2, and 9.9% to group 3. The occurrence of major postoperative complications significantly affected the start of chemotherapy (64.0 vs. 94.5 days; P = .044). Additionally, patients with 2 or more comorbidities were more likely to experience major complications (OR: 3.35; 95% CI: 1.03-10.95; P = .045) than those with 1 or 0. CONCLUSION: Major postoperative complications significantly delayed initiation of adjuvant chemotherapy in oncological patients who underwent radical breast surgery followed by immediate reconstruction with a latissimus dorsi myocutaneous flap and silicone implants.

Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction. The authors provide an update on recent advances in implant reconstruction techniques and contemporary expanded options for autologous tissue flap reconstruction as it relates to imaging modalities. As breast cancer screening is not routinely performed in this clinical setting, tumor recurrence after mastectomy and reconstruction is often detected by palpation at physical examination. Most local recurrences occur within the skin and subcutaneous tissue. Diagnostic breast imaging continues to have a critical role in confirmation of disease recurrence. Knowledge of the spectrum of benign and abnormal imaging appearances in the reconstructed breast is important for postoperative evaluation of patients, including recognition of early and late postsurgical complications and breast cancer recurrence. The authors provide an overview of multimodality imaging of the postmastectomy reconstructed breast, as well as an update on screening guidelines and recommendations for this unique patient population. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Postoperative Magnesium Sulfate Repletion Decreases Narcotic Use in Abdominal-Based Free Flap Breast Reconstruction.

BACKGROUND: Microsurgical breast reconstruction after mastectomy is now the standard of care for breast cancer patients. However, the costs and resources involved in free flap reconstruction can vary across different medical settings. To enhance patient outcomes in a cost-effective manner, we investigated the effect of intravenous magnesium sulfate (IV Mg) on postoperative opioid usage in this context. METHODS: A retrospective chart review was performed on all consecutive patients who underwent abdominal-based free flap breast reconstruction in a single institute following an enhanced recovery after surgery (ERAS) protocol. Patients who received IV Mg were compared with those who did not receive supplementation. Serum magnesium levels at different time points, narcotic consumption in units of oral morphine milligram equivalents (MMEs), and other postoperative recovery parameters were compared. RESULTS: Eighty-two patients were included. Those who received IV Mg on postoperative day 0 (n = 67) showed significantly lower serum magnesium levels before repletion (1.5 vs. 1.7 mg/dL, p = 0.004) and significantly higher levels on postoperative day 1 after repletion (2.2 vs. 1.7 mg/dL, p = 0.0002) compared to patients who received no magnesium repletion (n = 13). While both groups required a similar amount of narcotics on postoperative day 0 (20.2 vs. 13.2 MMEs, p = 0.2), those who received IV Mg needed significantly fewer narcotics for pain control on postoperative day 1 (12.2 MMEs for IV Mg vs. 19.8 MMEs for No Mg, p = 0.03). Recovery parameters, including maximal pain scores, postoperative mobilization, and length of hospital stay, did not significantly differ between the two groups. CONCLUSION: This is the first study to describe the potential analgesic benefits of routine postoperative magnesium repletion in abdominal-based free flap reconstruction. Further research is necessary to fully understand the role of perioperative magnesium supplementation as part of an ERAS protocol.

Quality of life and satisfaction of patients after oncoplastic or traditional breast-conserving surgery using the BREAST-Q (BCT module): a prospective study.

INTRODUCTION: The oncoplastic conservative surgery was developed as a natural evolution of traditional surgery, attempting to improve the therapeutic and aesthetic outcomes where tumor resection could be followed by not-adequate results. Our primary aim is to evaluate how patient satisfaction and quality-of-life after conservative oncoplastic surgery, using BREAST-Q (BCT Module), change pre- and post-operatively. The secondary aim is to compare patient-reported outcome after oncoplastic or traditional conservative surgery. PATIENTS AND METHODS: We enrolled 647 patients who underwent traditional conservative surgery or oncoplastic surgery from January 2020 to December 2022. Only 232 women (35.9%) completed the BREAST-Q questionnaire on a web-based platform, at the preoperative phase and 3 months after treatment. RESULTS: The average score of "Psychosocial well-being" and "Satisfaction with Breasts" 3 months after surgery showed a statistically significant improvement, while the average score for "Physical well-being: Chest" at 3 months showed a worsening compared to the baseline. "Sexual well-being" did not show statistically significant change. A significant difference between the post-operative outcome of oncoplastic surgery and traditional surgery was observed only for Physical well-being (better for traditional surgery). CONCLUSIONS: The study showed significant improvement in patient-reported outcomes 3 months after the surgery, except for physical discomfort that increases especially after oncoplastic surgery. Furthermore, our data, as well as many others, point to the appropriateness of using OCS where there is an effective indication, while the perspective of patients cannot find significant superiority over TCS in any of the areas analyzed.

Hyperbaric Oxygen Therapy for Threatened Nipple-Sparing Mastectomy Flaps: An Adjunct for Flap Salvage.

BACKGROUND: Nipple-sparing mastectomy (NSM) is emerging as the standard of care for treatment of breast cancer because of its oncologic safety and superior aesthetic outcomes. However, ischemia or necrosis of the skin flap and/or nipple-areola complex remain frequent complications. Hyperbaric oxygen therapy (HBOT) has emerged as a potential adjunct for flap salvage, although it is not currently a widely accepted practice. Here we review our institution's experience using a protocol of HBOT in patients with signs of flap ischemia or necrosis after NSM. METHODS: Retrospective review identified all patients treated with HBOT at our institution's hyperbaric and wound care center because of signs of ischemia after NSM. Treatment parameters consisted of 90-minute dives at 2.0 atmosphere once or twice daily. Patients unable to tolerate dives were considered a treatment failure, whereas those lost to follow-up were excluded from analysis. Patient demographics, surgical characteristics, and treatment indications were recorded. Primary outcomes assessed were flap salvage (no operative revision), need for revision procedures, and treatment complications. RESULTS: A total of 17 patients and 25 breasts met the inclusion criteria. The mean ± SD time to initiation of HBOT was 9.47 ± 12.7 days. The mean ± SD age was 46.7 ± 10.4 years, and mean ± SD follow-up time was 36.5 ± 25.6 days. Indications for NSM included invasive cancer (41.2%), carcinoma in situ (29.4%), and breast cancer prophylaxis (29.4%). Initial reconstruction included tissue-expander placement (47.1%), autologous reconstruction with deep inferior epigastric flaps (29.4%), and direct-to-implant reconstruction (23.5%). Hyperbaric oxygen therapy indications included ischemia or venous congestion for 15 breasts (60.0%) and partial thickness necrosis for 10 breasts (40.0%). Flap salvage was achieved in 22 of 25 breasts (88.0%). Reoperation was required for 3 breasts (12.0%). Hyperbaric oxygen therapy-related complications were observed in 4 patients (23.5%), which included 3 patients with mild ear pain and 1 patient with severe sinus pressure leading to treatment abortion. CONCLUSIONS: Nipple-sparing mastectomy is an invaluable tool for breast and plastic surgeons to achieve oncologic and cosmetic goals. However, ischemia or necrosis of the nipple-areola complex or mastectomy skin flap remains frequent complications. Hyperbaric oxygen therapy has emerged as a possible intervention for threatened flaps. Our results demonstrate the utility of HBOT in this population to achieve excellent NSM flap salvage rates.

Breast augmentation under local anesthesia with intercostal blocks and light sedation.

INTRODUCTION: This study of breast augmentations performed under local anesthesia with intercostal blocks and light sedation describes the outcomes and evaluates benefits and complications. METHOD: From December 2005 until August 2019, 335 women consecutively underwent bilateral breast augmentation procedures. The anesthetic protocol consisted of an initial intravenous bolus of 1 mg midazolam and 0.25 mg alfentanil preoperatively. In 2017, this was changed to 2-4 mg midazolam intramuscularly, 1 mg midazolam intravenously, and 2.5 µg sufentanil intravenously. Intercostal blocks were injected at the midaxillary line into the intercostal spaces two to seven. The operating field was infiltrated with tumescent local anesthesia. Retrospective data extraction from patients' medical charts was done, registering demographics, dosage of anesthesia, surgical characteristics, complications, and reoperation rates. RESULTS: Two hundred and eighty-one women underwent primary augmentation and 54 had implant replacement. The most common complications included suboptimal cosmetic results, asymmetry, and healing-related problems. The overall rate of reoperation was 16.1% within an average follow-up period of 2 years, ranging from 0 to 12.5 years. The majority of the reoperations were due to cosmetic reasons. The change in anesthetic regime was associated with a significantly (p < 0.0001) decreased need for supplementary medication with no increased risk of complications. CONCLUSION: Breast augmentations in local anesthesia with intercostal blocks and light sedation can be performed safely and can serve as an alternative to procedures in general anesthesia.

A descriptive comparison of satisfaction and well-being between expander-based and direct-to-implant breast reconstruction after Nipple-Sparing Mastectomy.

BACKGROUND: The literature that has explored differences between direct-to-implant (DTI) and expander-based (EB) breast reconstruction has mainly focused on complications, with results not always unambiguous. Moreover, there are limited data 1) comparing DTI and EB breast reconstruction after nipple-sparing mastectomy (NSM) and 2) from the patient's perspective. AIM: The aim of this study was to compare satisfaction and well-being in patients undergoing DTI and EB reconstruction after NSM in a Comprehensive Cancer Center, exploring what factors can be related to satisfaction and well-being. METHOD: The study design is monocentric, observational and retrospective. The participants completed an online questionnaire containing the Breast-Q and some socio-demographic variables (year of birth, level of education, civil status). Clinical information was obtained from the institutional database. Surgical techniques in the two branches of NSM were similar: all skin incisions, lateral to the areola; all implants, subpectoral (EB: conventionally submuscular; DTI: dual-plane pocket); all without synthetic mesh or acellular tissue matrix. RESULTS: A total of 120 patients (45% with EB and 55% with DTI) completed the questionnaire. We found that there are no differences between EB and DTI concerning the satisfaction and well-being of NSM patients, except for satisfaction with information, which is greater in the DTI group. In EB patients, no variables among those explored are related to satisfaction and well-being. In DTI patients, level of education is positive related to satisfaction with implants and physical well-being, Tumor-Node-Metastasis (TNM) and body mass index (BMI) are negative related to satisfaction with information and TNM also with satisfaction for plastic surgery. CONCLUSION: EB and DTI do not differ in terms of patient well-being, but EB requires a more careful counselling by the surgeon.

Immediate Prosthesis Breast Reconstruction: A Comparison Between Ambulatory Surgery Versus Traditional Hospitalization Based on the Propensity Score Matching Method.

BACKGROUND: The positive benefits of immediate prosthesis breast reconstruction (IPBR) are incontrovertible. During the COVID-19 pandemic, health care resources became scarce. The implementation of outpatient immediate prosthesis breast reconstruction (OIPBR) can improve the efficiency of medical care and reduce viral exposure. Very few studies have focused on OIPBR and this study aimed to fill this gap by evaluating outcomes of OIPBR compared with traditional hospitalization IPBR (THIPBR) in terms of complications and quality of life. MATERIAL AND METHODS: The study enrolled patients undergoing IPBR at Tianjin Medical University Cancer Institute and Hospital between January 1, 2020, and September 30, 2021. Outcomes were defined as postoperative complications and quality of life before reconstruction and at 3-month follow-up. Quality of life was assessed by BREAST-Q questionnaire. Inverse probability of treatment weighting and propensity score matching (PSM) were applied to adjust for confounders. RESULTS: A total of 135 patients were enrolled, including 110 with THIPBR and 25 with OIPBR. After matching, baseline characteristics were well balanced. Patients with OIPBR had lower rates of lymphedema on the surgery side (p = 0.041) and readmission (p = 0.040) than patients with THIPBR. No statistically significant differences in the quality of life metrics of psychosocial well-being, sexual well-being, satisfaction with breast and physical well-being of the chest were found between the two groups. CONCLUSION: OIPBR is a safe and efficient alternative to THIBPR during the COVID-19 pandemic. It is recommended when medical conditions allow to conserve medical resources. Accelerated technical training for the performance of OIPBR at the hospital level should be expedited.

Total autologous breast reconstruction with the Kiss Latissimus Dorsi Flap.

INTRODUCTION: Patients presenting breast actinic damage or implant-related complications require an autologous approach to breast reconstruction. However, when they are not good candidates for microsurgical procedures, alternative solutions must be sought. Latissimus dorsi (LD) is a workhorse flap in breast reconstruction, but often the amount of skin and volume achievable are insufficient. Taking inspiration from the Kiss flap concept, the authors hereby describe the "Kiss" LD flap to achieve totally autologous breast reconstruction. PATIENTS AND METHODS: A prospective service evaluation of all patients who underwent breast reconstruction with Kiss LD flap between 2018 and 2020 was performed. Patient demographics and operative variables were recorded, together with early and late complications. Patient satisfaction and quality of life were registered using the latest BREAST-Q reconstruction module, which includes specific LD scales. The questionnaire was administered to patients preoperatively and six months postoperatively. RESULTS: Thirty patients underwent total autologous breast reconstruction with Kiss LD flap. Breast cancer and breast sarcoma resection were followed by reconstruction. The timing of reconstruction was immediate in 3 cases and delayed in 27 cases. No major complications nor total flap loss were registered. BREAST-Q scores postoperatively were significantly higher than the preoperative ones in every domain (p<0.0001) except for the physical well-being of back and shoulder, where the scores differed slightly and non-significantly (p=0.05). CONCLUSIONS: The Kiss LD flap allows to harvest a large amount of skin to restore the breast envelope and a considerable volume to reconstruct the breast mound in a completely autologous procedure.

Breast reconstruction with silicone prosthesis and acellular dermal matrix of porcine origin: Retrospective study of 84 cases.

INTRODUCTION: Breast reconstruction (BR) using a prosthesis implant (PI) associated with an acellular dermal matrix (ADM) is a known method that has been the subject of discussion in recent years. The objective of this study was to quantify the rate of PI removal after BR using prosthesis combined with ADM, and to identify the risk factors in the event of removal. METHODS: This was a retrospective study conducted between 2010 and 2015. Inclusion criteria were patients who had undergone immediate (IBR) or delayed (DBR) breast reconstruction with placement of a PI associated with porcine ADM. The primary endpoint was the postoperative removal of the PI. RESULTS: In all, 84 reconstructions were performed. The mean age of the population was 57.5 years. 25.9% of the patients were active smokers at the time of surgery. 89.5% of patients had previously benefited from ipsilateral breast radiation therapy (IBRT) in DBR, 10.5% in IBR. The PI deposition rate, all BR combined, was 21.4%. It was 52.17% in smokers and 9.84% in non-smokers (P<0.0001), making smoking an independent risk factor for reconstruction failure (hazard ratio (HR)=7.4, 95%CI [2.64-20.9]). IBRT was also a risk factor for PI removal, especially when performed after IBR (HR=8.1, 95%CI [1.1-62.1]). CONCLUSION: Smoking and adjuvant IBRT are risk factors for failure of reconstruction by PI associated with ADM. This type of reconstruction should be selected for non-smokers who have not undergone IBRT and therefore could be a therapeutic alternative in the BR panel.

Neoadjuvant chemotherapy and radiotherapy for locally advanced breast cancer: Safety and efficacy of reverse sequence compared to standard technique?

BACKGROUND: The reverse sequence of neoadjuvant chemotherapy, preoperative radiotherapy, mastectomy then immediate breast reconstruction is currently proposed for selected patients with locally advanced breast cancer. Few studies have compared it to the standard sequence of neoadjuvant chemotherapy, mastectomy and radiotherapy with or without differed reconstruction. Our study compares overall (OS) and recurrence-free (RFS) survivals of breast cancer patients treated with reverse sequence compared to the standard technique. METHODS: In this retrospective, single center study at a Comprehensive Cancer Center in France, patients were included if: female, age <65y, had received neoadjuvant chemotherapy, mastectomy and radiotherapy, and were M0. Outcomes for patients treated by reverse sequence (RS) are compared to those for patients treated by standard sequence (ST). Data was collected from medical records. RESULTS: From January 2009 to April 2018, 222 eligible patients were treated, 46 by RS and 176 by ST. Mean follow-up was 61.7 months. Five-year OS and RFS did not differ between groups. 5-yr OS: 88.4% 95%CI [74.1-95.0] for RS and 81.5% 95%CI [74.0-87.0] for ST (P = 0.4412); 5-yr RFS: 78.3% 95%CI [61.9-88.3] for RS and 70.1% 95%CI [62.2-76.7] for ST (P = 0.3003). Overall treatment time was significantly shorter in the RS group, and the rate of severe surgical complications did not differ between groups. CONCLUSIONS: For locally advanced breast cancer patients with an indication for radiation therapy the reverse sequence offers similar safety and efficacy results as the standard treatment while allowing immediate breast reconstruction. However, careful patient selection is necessary, particularly with regard to preoperative lymph node invasion.

The Efficacy of Local Anesthesia for Postoperative Pain Control in Breast Augmentation Surgery: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Breast augmentation can cause severe postoperative pain; therefore, some surgeons perform wound infiltration with a local anesthetic solution. This study investigated the postoperative pain relief of local analgesics in breast augmentation surgery. METHODS: We searched three databases for randomized controlled trials evaluating the outcomes of local wound irrigation with local analgesics during or after breast augmentation surgery. The solutions included ropivacaine, bupivacaine, bupivacaine plus ketorolac. The control groups may be saline alone or no irrigation. Network meta-analysis was further employed based on the frequentist approach. Outcomes were reported as weighted mean differences with 95% confidence intervals. RESULTS: Comparisons between the interventions of our included studies revealed that only bupivacaine plus ketorolac (versus placebo) significantly reduced pain at 1 h postoperatively, as indicated by the visual analog scale pain score reduction of 2.22 (- 3.98, - 0.47). Other comparisons showed no significant differences. Moreover, three of the included studies reported postoperative medication use. Two of them reported that postoperative narcotic use was reduced, but the others did not report any such reduction. CONCLUSIONS: Our results showed possibility that local irrigation with bupivacaine plus ketorolac might reduce pain 1 h after surgery. In addition, local anesthesia might reduce postoperative narcotic use. However, due to the small number of included studies, the clinical benefits of local anesthesia in breast augmentation surgery require further confirmation.

Short Stay Management of Locally Advanced Breast Cancer Using Immediate Local Thoracoabdominal Advancement Flap and Enhanced Recovery After Surgery Protocol.

BACKGROUND: Patients with locally advanced invasive breast cancer (LABC) are often considered inoperable, because of the anticipated chest wall defect and need for complex reconstruction. We present a series of patients who underwent mastectomy with extensive skin resection and immediate chest wall reconstruction using a local thoracoabdominal advancement flap (TAAF). All patients were managed after surgery with an ERAS (Enhanced Recovery After Surgery) protocol, to decrease length of stay in hospital. We also present 1 patient who subsequently had satisfactory bilateral delayed breast reconstruction with pedicled latissimus dorsi myocutaneous flaps with prepectoral silicone implants. METHODS: This is a single-surgeon, single-institution retrospective chart review of patients with LABC who underwent mastectomy with skin resection and local TAAF from May 2017 to October 2019, with minimum 3-month follow-up. RESULTS: Thirteen patients met inclusion criteria. Twelve of 13 patients presented with stage III or IV invasive breast cancer, with skin involvement. The mean chest wall defect measured 248.7 cm2 (140-336 cm2; SD, 63.2 cm2), and all were successfully reconstructed with immediate local TAAF. There were no intraoperative complications, but 1 patient developed a postop hematoma. The mean hospital stay was 1.3 nights, with 9 patients (69.2%) staying less than 23 hours and 4 patients (30.8%) staying 2 nights. Nine patients (69.2%) underwent adjuvant therapy, beginning on average 32 days (13-55 days; SD, 13.1 days) after surgery. The mean follow-up time was 13.8 months (4.5-31.6 months; SD, 9.2 months). One patient underwent successful delayed bilateral breast reconstruction with pedicled latissimus dorsi myocutaneous flaps and silicone implant placement. CONCLUSIONS: Our study demonstrates that reconstruction with local TAAF is an outpatient procedure that reliably provides durable, immediate chest wall coverage, after mastectomy in patients with LABC. This technique has a short operative time, low blood loss, and low complication rate, allowing timely adjuvant therapy. Using an ERAS postop protocol we were able to reduce mean hospital stay to 1.3 days. Compared with other described techniques of reconstruction, the additional scars and donor site morbidity are minimal, allowing for delayed breast reconstruction. We also present survival outcomes data on these surgically managed patients.

Biomechanical Principles of Breast Implants and Current State of Research in Soft Tissue Engineering for Cosmetic Breast Augmentation.

Currently there are limited implant-based options for cosmetic breast augmentation, and problems associated with those have been increasingly appreciated, most commonly capsular contracture, which occurs due to a chronic foreign body reaction against non-degradable implant materials such as silicone and polyurethane leading to scar tissue formation, pain, and deformity. The underlying biomechanical concepts with implants create a reciprocal stress-strain relationship with local tissue, whilst acting as a deforming force. This means that with time, as the implant continues to have an effect on surrounding tissue the implant and host's biomechanical properties diverge, making malposition, asymmetry, and other complications more likely. Research directed towards development of alternative therapies based on tissue engineering and regenerative medicine seeks to optimize new tissue formation through modulation of tissue progenitors and facilitating tissue regeneration. Scaffolds can guide the process of new tissue formation by providing both an implant surface and a three-dimensional space that promotes the development of a microenvironment that guides attachment, migration, proliferation, and differentiation of connective tissue progenitors. Important to scaffold design are the architecture, surface chemistry, mechanical properties, and biomaterial used. Scaffolds provide a void in which vascularization, new tissue formation, and remodelling can sequentially occur. They provide a conduit for delivery of the different cell types required for tissue regeneration into a graft site, facilitating their retention and distribution. Whilst recent research from a small number of groups is promising, there are still ongoing challenges to achieving clinical translation. This article summarizes the biomechanical principles of breast implants, how these impact outcomes, and progress in scaffold-guided tissue engineering approaches to cosmetic breast augmentation.

What is the role of locoregional anesthesia in breast surgery? A systematic literature review focused on pain intensity, opioid consumption, adverse events, and patient satisfaction.

BACKGROUND: Breast surgery in the United States is common. Pain affects up to 50% of women undergoing breast surgery and can interfere with postoperative outcomes. General anesthesia is the conventional, most frequently used anaesthetic technique. Various locoregional anesthetic techniques are also used for breast surgeries. A systematic review of the use of locoregional anesthesia for postoperative pain in breast surgery is needed to clarify its role in pain management. OBJECTIVES: To systematically review literature to establish the efficacy and the safety of locoregional anesthesia used in the treatment of pain after breast surgery. METHODS: Embase, MEDLINE, Google Scholar and Cochrane Central Trials Register were systematically searched in Mars 2020 for studies examining locoregional anesthesia for management of pain in adults after breast surgery. The methodological quality of the studies and their results were appraised using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist and specific measurement properties criteria, respectively. RESULTS: Nineteen studies evaluating locoregional anesthesia were included: 1058 patients underwent lumpectomy/mastectomy, 142 breast augmentation and 79 breast reduction. Locoregional anesthesia provides effective anesthesia and analgesia in the perioperative setting, however no statistically significant difference emerged if compared to other techniques. For mastectomy only, the use of locoregional techniques reduces pain in the first hour after the end of the surgery if compared to other procedures (p = 0.02). Other potentially beneficial effects of locoregional anesthesia include decreased need for opioids, decreased postoperative nausea and vomiting, fewer complications and increased patient satisfaction. All this improves postoperative recovery and shortens hospitalization stay. In none of these cases, locoregional anesthesia was statistically superior to other techniques. CONCLUSION: The results of our review showed no differences between locoregional anesthesia and other techniques in the management of breast surgery. Locoregional techniques are superior in reducing pain in the first hour after mastectomy.

Secondary "Hybrid Reconstruction" Concept with Silicone Implants After Autologous Breast Reconstruction - Is It Safe and Reasonable?

BACKGROUND The use of autologous tissue for breast reconstructive surgery following mastectomy has become routine and allows for excellent symmetry and aesthetic results. However, in some cases, the amount of tissue available from the utilized flaps is not enough to achieve the desired outcome. The use of autologous fat grafting, as well as other techniques, has been described to deal with such problems. However, though well-established, these techniques may also fail to achieve the desired results. The aim of this study was to highlight the opportunity to improve aesthetic results using a secondary prosthesis underneath the previously used free flap and to examine whether this is a safe and reasonable procedure. MATERIAL AND METHODS In our study we included patients with unsatisfied aesthetic results after free flap procedures (DIEP, S-GAP, TMG, and FCI) between 2011 and 2018. In each case described, a secondary prosthesis was placed underneath the original flap in order to improve symmetry, shape and projection. Patient age, indication for surgery, adjuvant therapy, complications and outcomes have been registered. A 12-point scale was established to analyze patient satisfaction and aesthetic outcome. RESULTS Overall "operative success" was achieved in all 13 patients (14 flaps) evaluated. At 12 months after reconstruction, all aesthetic scores collected were between good and excellent. In contrast to other studies, we chose a secondary approach for the flap augmentation and we used the epipectoral pocket for the placement of the implant. In our series, low rates of early and late post-operative complications were observed, with a high overall rate of satisfaction. CONCLUSIONS The demonstrated "Hybrid Breast Reconstruction" approach, using an implant underneath a free flap autologous breast reconstruction, provided a safe and reliable option to optimize breast reconstruction outcomes.

Experiences of implant loss after immediate implant-based breast reconstruction: qualitative study.

BACKGROUND: Immediate implant-based breast reconstruction (IBBR) is the most commonly performed reconstructive procedure in the UK, but almost one in ten women experience implant loss and reconstructive failure after this technique. Little is known about how implant loss impacts on patients' quality of life. The first phase of the Loss of implant Breast Reconstruction (LiBRA) study aimed to use qualitative methods to explore women's experiences of implant loss and develop recommendations to improve care. METHODS: Semistructured interviews were conducted with a purposive sample of women who experienced implant loss after immediate IBBR, performed for malignancy or risk reduction across six centres. Interviews explored decision-making regarding IBBR, and experiences of implant loss and support received. Thematic analysis was used to explore the qualitative interview data. Sampling, data collection and analysis were undertaken concurrently and iteratively until data saturation was achieved. RESULTS: Twenty-four women were interviewed; 19 had surgery for malignancy and five for risk reduction. The median time between implant loss and interview was 42 (range 22-74) months. Ten women had undergone secondary reconstruction, two were awaiting surgery, and 12 had declined further reconstruction. Three key themes were identified: the need for accurate information about the risks and benefits of IBBR; the need for more information about 'early-warning' signs of postoperative problems, to empower women to seek help; and better support following implant loss. CONCLUSION: Implant loss is a devastating event for many women. Better preoperative information and support, along with holistic patient-centred care when complications occur, may significantly improve the experience and outcome of care.

ANTECEDENTES: La reconstrucción mamaria inmediata con prótesis (implant-based breast reconstruction, IBBR) es el procedimiento reconstructivo más utilizado en el Reino Unido, pero casi una de cada diez mujeres presentará pérdida de la prótesis y fallo del procedimiento reconstructivo tras esta técnica. Se sabe poco de cómo la pérdida de la prótesis afecta la calidad de vida de las pacientes. La primera fase del estudio LiBRA tuvo como objetivo explorar la percepción de las mujeres ante la pérdida de la prótesis, utilizando métodos cualitativos, y proponer una serie de medidas para mejorar la atención sanitaria de estas pacientes. MÉTODOS: Se realizaron entrevistas semiestructuradas en una muestra de mujeres que padecieron la pérdida de la prótesis tras una IBBR inmediata, realizada por neoplasia o como procedimiento de reducción de riesgo, en seis centros. Las entrevistas analizaron la toma de decisiones con respecto a la IBBR inmediata, así como la percepción ante la pérdida del implante y el soporte recibido. Se utilizó un análisis por temas para examinar los datos de la entrevista cualitativa. El muestreo, la recopilación de datos y el análisis se realizaron de forma simultánea e iterativa hasta que se logró la saturación de datos. RESULTADOS: Se entrevistaron 24 pacientes; 19 en las que la indicación quirúrgica fue por cáncer y 5 por reducción de riesgo. La mediana del tiempo entre la pérdida del implante y la entrevista fue de 42 (rango 22-52) meses. Diez mujeres se habían sometido a una reconstrucción secundaria; dos estaban a la espera de la cirugía y 12 habían rechazado la reconstrucción posterior. Se identificaron tres temas clave, siendo las necesidades de: i) información precisa sobre los riesgos y beneficios de la IBBR, ii) más información sobre los signos de "alarma precoz" de las complicaciones postoperatorias que permitiesen a las mujeres buscar ayuda, y iii) mejor soporte tras la pérdida de la prótesis. CONCLUSIÓN: La pérdida de una prótesis es una complicación catastrófica para muchas mujeres. Una mejor información y apoyo preoperatorios, junto con una atención holística centrada en la paciente cuando se presentan las complicaciones, podrían mejorar significativamente la experiencia y el resultado de la atención.

Therapeutic mammaplasty is a safe and effective alternative to mastectomy with or without immediate breast reconstruction.

BACKGROUND: Therapeutic mammaplasty (TM) may be an alternative to mastectomy, but few well designed studies have evaluated the success of this approach or compared the short-term outcomes of TM with mastectomy with or without immediate breast reconstruction (IBR). Data from the national iBRA-2 and TeaM studies were combined to compare the safety and short-term outcomes of TM and mastectomy with or without IBR. METHODS: The subgroup of patients in the TeaM study who underwent TM to avoid mastectomy were identified, and data on demographics, complications, oncology and adjuvant treatment were compared with those of patients undergoing mastectomy with or without IBR in the iBRA-2 study. The primary outcome was the percentage of successful breast-conserving procedures in the TM group. Secondary outcomes included postoperative complications and time to adjuvant therapy. RESULTS: A total of 2916 patients (TM 376; mastectomy 1532; mastectomy and IBR 1008) were included in the analysis. Patients undergoing TM were more likely to be obese and to have undergone bilateral surgery than those having IBR. However, patients undergoing mastectomy with or without IBR were more likely to experience complications than the TM group (TM: 79, 21·0 per cent; mastectomy: 570, 37·2 per cent; mastectomy and IBR: 359, 35·6 per cent; P < 0·001). Breast conservation was possible in 87·0 per cent of patients who had TM, and TM did not delay adjuvant treatment. CONCLUSION: TM may allow high-risk patients who would not be candidates for IBR to avoid mastectomy safely. Further work is needed to explore the comparative patient-reported and cosmetic outcomes of the different approaches, and to establish long-term oncological safety.

ANTECEDENTES: La mamoplastia terapéutica (therapeutic mammaplasty, TM) puede ser una alternativa a la mastectomía, pero hay pocos estudios bien diseñados que hayan evaluado el éxito de esta estrategia o hayan comparado los resultados a corto plazo de la TM con la mastectomía con o sin (+/-) reconstrucción mamaria inmediata (immediate breast reconstruction, IBR). Para comparar la seguridad y los resultados a corto plazo de la TM y la mastectomía +/- IBR se combinaron los datos de los estudios nacionales iBRA-2 y TeaM. MÉTODOS: En el estudio TeaM se identificó el subgrupo de pacientes al que se realizó una TM para evitar la mastectomía y se compararon los datos demográficos, las complicaciones, los resultados oncológicos y el tratamiento adyuvante con las pacientes sometidas a mastectomía +/- IBR del estudio iBRA-2. La variable principal fue el porcentaje de éxito de la cirugía conservadora de mama en el grupo TM. Las variables secundarias fueron las complicaciones postoperatorias y el intervalo de tiempo hasta el inicio del tratamiento adyuvante. RESULTADOS: Se incluyeron en el análisis 2.916 pacientes (TM n = 376; mastectomía n = 1.532; IBR n = 1.008). La TM era más frecuente en pacientes obesas o en las sometidas a cirugía bilateral en comparación con las pacientes con IBR. Sin embargo, las pacientes sometidas a una mastectomía +/- IBR tenían más probabilidades de desarrollar complicaciones que las del grupo TM (TM n = 79, 21,0%; mastectomía n = 570, 37,2%; mastectomía y IBR n = 359, 35,6%; P < 0,001). La conservación de la mama fue posible en el 87% de las pacientes con TM y el procedimiento no retrasó el inicio del tratamiento adyuvante. CONCLUSIÓN: La TM puede permitir que pacientes de alto riesgo que no serían candidatas a IBR eviten la mastectomía de una forma segura. Se necesitan más trabajos para comparar los resultados percibidos por las pacientes y los estéticos de las diferentes estrategias terapéuticas y establecer la seguridad oncológica a largo plazo.

Aesthetic Breast Surgery Under Cold Tumescent Anesthesia: Feasibility and Safety in Outpatient Clinic.

Throughout the last decade, aesthetic breast surgery has enormously spread in the outpatient clinic setting where plastic surgeons perform the vast majority of procedures under local anesthesia as day-case operations. The "tumescent anesthesia" is defined as the injection of a dilute solution of local anesthetic combined with epinephrine and sodium bicarbonate into subcutaneous tissue until it becomes firm and tense, which is "tumescent." The "cold tumescent anesthesia" (CTA) derives from Klein's solution with the introduction of a new concept, which is the low temperature (4°C) of the injected solution. This novelty adds further anesthetic and hemostatic power to the well-known benefits of tumescent anesthesia. The authors report their experience with CTA in the last 15 years in the setting of aesthetic breast surgery, describing in detail the anesthesia protocol, surgical outcomes, and patient satisfaction. A total of 1541 patients were operated on during the study period and were included in this retrospective analysis. The types of breast procedures were breast augmentation in 762 cases (49.4%), mastopexy with implants in 123 patients (8.0%), mastopexy without implants in 452 cases (29.3%), and breast reduction in 204 cases (13.3%). Patient mean age was 42.8 years (range, 18-67 years). The mean operating time was 37 ± 32 minutes for breast augmentation, 78 ± 24 minutes for mastopexy with implants, 58 ± 18 minutes for mastopexy without implants, and 95 ± 19 minutes for breast reduction. No major complications occurred, and no conversion to general anesthesia was required. The median recovery time was 150 minutes (range, 120-210 minutes), and all patients were discharged within 3 hours after surgery. Wound or implant infections occurred in 33 patients (2.1%), wound dehiscences in 21 (1.4%), and postoperative bleeding requiring return to theater in 2 cases (0.1%). Thirteen patients (0.8%) developed capsular contracture. Fifteen patients (1%) required reintervention due to implant rotation or rupture. The median visual analog scale score was 1.8 (interquartile range, 1-3) after discharge. Patient satisfaction was very high in 91.3% (n = 1407) of the cases. In experienced hands, CTA can shorten operating time with high patient satisfaction and a low complication rate. These preliminary data could be hypothesis generating for future multicenter prospective trials done to confirm the benefits of CTA in other surgical fields.
