Review
Mastectomy skin-flap necrosis (MSFN) is one of the most feared complications of immediate implant-based breast reconstruction (IIBR). Traditionally, mastectomy skin-flap viability was based only on surgeons' clinical experience. Even though numerous studies have already addressed the patients' risk factors for MSFN, few works have focused on assessing quality of breast envelope. This review investigates mastectomy's flap viability-assessment methods, both preoperative (PMFA) and intraoperative (IMFA), to predict MSFN and its sequalae. Between June and November 2022, we conducted a systematic review of Pubmed/MEDLINE and Cochrane electronic databases. Only English studies regarding PMFA and IMFA applied to IIBR were selected. The use of digital mammography, ultrasound, magnetic resonance imaging, and a combination of several methods before surgery was shown to be advantageous by several authors. Indocyanine performed better than other IMFA, however both thermal imaging and spectroscopy demonstrated novel and promising results. Anyway, the best prediction comes when preoperative and intraoperative values are combined. Particularly in prepectoral reconstruction, when mastectomy flaps are essential to determine a successful breast reconstruction, surgeons' clinical judgment is insufficient in assessing the risk of MSFN. Preoperative and intraoperative assessment techniques play an emerging key role in MSFN prediction. However, although there are several approaches to back up the surgeon's processing choice, there is still a dearth of pertinent literature on the subject, and more research is required.

Review
BACKGROUND
To date, various surgical techniques were developed for gynecomastia and pseudogynecomastia surgery, providing surgeons vast range of options. These variations of techniques, however, may have different efficacy and results depending on the severity of patients' conditions.
OBJECTIVES
This review aims to delineate comprehensively the variations of surgical approaches to gynecomastia and pseudogynecomastia in relation to surgical and patients' outcomes.
METHODS
Database search (October 28, 2020) from PubMed, Scopus, Science Direct, and Cochrane Library was performed to identify relevant studies using the keywords ("gynecomastia" OR "pseudogynecomastia") AND ("surgery" AND "mastectomy" OR "liposuction") within January 2011-November 2020, published in English. Inclusion criteria were approached according to patients, intervention, comparator, outcomes, and study design (PICOS). Data from the included studies were extracted based on study and subjects' characteristics, type of intervention, and outcome measures.
RESULTS
Out of all relevant studies revealed, 53 studies met inclusion criteria with 5345 subjects included. Most subjects, from 44 studies, were classified as Simon's Grade II (68.49%) with idiopathic cause (94.51%). Most cases were approached using the minimally invasive techniques (37.50%) and were highly satisfied. Among intervention groups, complication rates vary from 12.12-22.30%, with the minimally invasive approach having the lowest rate. Hematoma and bruise were the most reported complications. However, the risk of bias was relatively high due to missing data.
CONCLUSIONS
Different surgical approaches for gynecomastia treatment have been described and were consistent with good outcomes. To achieve a low rate of complications, the minimally invasive techniques can be considered, since most patients seem to be satisfied.

Review
BACKGROUND
Hematomas are reported to be the most common immediate complication in patients undergoing gender-affirming mastectomy, with rates substantially higher than those associated with other types of breast surgery. This study sought to examine the breadth of current literature and provide evidence-based explanations regarding the development of hematomas in chest masculinizing surgery and technical considerations for reducing their incidence.
METHODS
A systematic review was conducted to identify all articles related to gender-affirming mastectomy published through September 2021. Literature search yielded 2,661 articles for screening, of which 20 met inclusion criteria. Themes from the selected articles were compiled to generate consensus statements qualified by associated level of evidence (LOE).
RESULTS
The rate of hematoma following gender-affirming mastectomy is reported in the literature ranging from 0% to 31.2%. The use of more limited, nipple-sparing incisions is associated with a higher hematoma rate than mastectomy with free nipple grafting (Level III). There is no conclusive evidence indicating any relationship between the use of masculinizing hormones and the incidence of hematoma (Level IV). Factors such as body mass index (Level III) and breast size (Level III) were not found to influence hematoma risk, though nicotine use (Level IV) was significantly associated with the incidence of hematoma.
CONCLUSIONS
Hematoma is a known complication following gender-affirming mastectomy. The use of limited incision approaches has the strongest association with an increased risk of hematoma. There is no evidence indicating an association between hormone use (i.e., testosterone) and hematoma incidence. Future studies are needed to better define factors, interventions, and protocols to reduce the rate of hematoma.

Breast Cancer Research and Treatment Sep 2020We performed a systematic review to document the spatial location of local recurrences (LR) after mastectomy. (Review)
Review
PURPOSE
We performed a systematic review to document the spatial location of local recurrences (LR) after mastectomy.
METHODS
A PubMed search was conducted in August 2019 for the following terms: breast [Title/Abstract] AND cancer [Title/Abstract] AND recurrence [Title/Abstract] AND mastectomy [Title/Abstract]. The search was filtered for English language. Exclusion criteria included studies that did not specify the LR location or studies reporting LR associated with inflammatory breast cancer, or other breast cancers such as phyllodes tumours, lymphoma or associated with sarcoma/angiosarcoma.
RESULTS
A total of 3922 titles were identified, of which 21 publications were eligible for inclusion in the final analysis. A total of 6901 mastectomy patients were included (range 25-1694). The mean LR proportion was 3.5%. Among the total of 351 LR lesions, 81.8% were in the subcutaneous tissue and the skin, while 16% were pectoral muscle recurrences.
CONCLUSION
Local recurrences are mostly located within the subcutaneous tissue and the skin, assumed to result from unrecognized/subclinical tumour foci left behind after mastectomy, surgical implantation of tumour cells in the wound/scar and/or tumour emboli within the subcutaneous lymphatics. Pectoral muscle recurrences are less frequent and may be attributed to residual disease along the posterior surgical margin and/or lymphatic involvement.

Review
: Lipofilling is a commonly performed procedure worldwide for breast augmentation and correction of breast contour deformities. In breast reconstruction, fat grafting has been used as a single reconstructive technique, as well as in combination with other procedures. The aim of the present study is to systematically review available studies in the literature describing the combination of implant-based breast reconstruction and fat grafting, focusing on safety, complications rate, surgical sessions needed to reach a satisfying reconstruction, and patient-reported outcomes. : We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol. A systematic review of the literature up to April 2022 was performed using Medline, Embase, and Cochrane Library databases. Only studies dealing with implant-based breast reconstruction combined with fat grafting were included. : We screened 292 articles by title and abstract. Only 48 articles were assessed for full-text eligibility, and among those, 12 studies were eventually selected. We included a total of 753 breast reconstructions in 585 patients undergoing mastectomy or demolitive breast surgeries other than mastectomy (quadrantectomy, segmentectomy, or lumpectomy) due to breast cancer or genetic predisposition to breast cancer. Overall, the number of complications was 60 (7.9%). The mean volume of fat grafting per breast per session ranged from 59 to 313 mL. The mean number of lipofilling sessions per breast ranged from 1.3 to 3.2. : Hybrid breast reconstruction shows similar short-term complications to standard implant-based reconstruction but with the potential to significantly decrease the risk of long-term complications. Moreover, patient satisfaction was achieved with a reasonably low number of lipofilling sessions (1.7 on average).

Meta-Analysis
BACKGROUND
Nipple-sparing mastectomy (NSM) has emerged as an alternative procedure for skin-sparing mastectomy (SSM), followed by immediate breast reconstruction. Because oncologic safety appears similar, patient-reported outcomes (PROs) and complication risks may guide decision-making in individual patients. Therefore, the aim of this systematic review was to compare PROs and complication rates after NSM and SSM.
METHODS
A systematic literature review evaluating NSM versus SSM was performed using the Embase, MEDLINE, and Cochrane databases. Methodologic quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Form for Cohort Studies. Primary outcomes were PROs and complications. Studies that evaluated BREAST-Q scores were used to perform meta-analyses on five BREAST-Q domains.
RESULTS
Thirteen comparative studies including 3895 patients were selected from 1202 articles found. Meta-analyses of the BREAST-Q domains showed a significant mean difference of 7.64 in the Sexual Well-being domain ( P = 0.01) and 4.71 in the Psychosocial Well-being domain ( P = 0.03), both in favor of NSM. Using the specifically designed questionnaires, no differences in overall satisfaction scores were found. There were no differences in overall complication rates between the two groups.
CONCLUSIONS
Patient satisfaction scores were high after both NSM and SSM; however, NSM led to a higher sexual and psychosocial well-being. No differences in complication rates were found. In combination with other factors, such as oncologic treatments, complication risk profile, and fear of cancer recurrence, the decision for NSM or SSM has to be made on an individual basis and only if NSM is considered to be oncologically safe.

Gland Surgery Jun 2021This study aimed to describe the locations of local recurrences based on the mastectomy and reconstruction type in breast cancer patients. (Review)
Review
BACKGROUND
This study aimed to describe the locations of local recurrences based on the mastectomy and reconstruction type in breast cancer patients.
METHODS
In November 2020, a systematic literature review was performed through MEDLINE/PubMed and the Cochrane Centre Register of Controlled Trials. Publications that included skin-sparing or nipple-sparing mastectomy followed by breast reconstruction and described the location of local recurrences were analyzed. Exclusion criteria included salvage or prophylactic mastectomy, unclear distinction between local and regional recurrences, rare tumor types.
RESULTS
From 19 publications, 272 local recurrences lesions were reported in a total of 4,787 patients. After autologous reconstruction (n=2,465), local recurrences were located in the skin in 45 (1.8%) patients, in the chest wall in 18 (0.7%), and in the nipple-areolar complex in 9 (0.4%). After implant reconstruction (n=1,917), local recurrences sites included the skin in 91 (4.7%) patients, chest wall in 8 (0.4%), and nipple-areolar complex in 8 (0.4%). Of the 70 lesions with reported in-breast location, 57 (81.4%) relapsed in the original tumor location.
DISCUSSION
Although meta-analysis was not conducted, present analysis demonstrated that most local recurrences after skin-sparing or nipple-sparing mastectomy occurred within the skin or subcutaneous tissues. It was found that the original tumor location was the most frequent site of relapse. Therefore, special attention should be paid to the original tumor overlying the skin while planning postmastectomy radiation therapy.

Meta-Analysis
STUDY OBJECTIVE
To identify whether adding ketamine to the local anesthetics (LA) in the regional anesthesia could prolong the duration of analgesia.
DESIGN
A Systematic review and meta-analysis of randomized controlled trials.
SETTING
The major dates were obtained in the operating room and the postoperative recovery ward.
PATIENTS
A total of 1011 patients at ASA physical status I and II were included in the analysis. Procedure performed including cesarean section, orthopedic, radical mastectomy, urological or lower abdominal surgery and intracavitary brachytherapy implants insertion.
INTERVENTIONS
After an extensive search of the electronic database, patients received regional anesthesia combined or not combined general anesthesia and with or without adding ketamine to LA were included in the analysis. The regional anesthesia includes spinal anesthesia, brachial plexus block, pectoral nerve block, transversus abdominis plane block and femoral and sciatic nerve block.
MEASUREMENT
The primary outcome was the duration of analgesia. Secondary outcomes were the duration and onset time of motor and sensory block as well as the ketamine-related adverse effect. Data are expressed in mean differences in continuous data and odds ratios (OR) for dichotomous data with 95% confidence intervals. The risk of bias of the included studies was evaluated using the revised Cochrane risk of bias tool for randomized trials. The quality of evidence for each outcome was rated according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Working Group system.
MAIN RESULT
Twenty randomized controlled trials were included in the analysis. When ketamine was used as an adjuvant to LA, the duration of analgesia could be prolonged(172.21 min, 95% CI, 118.20 to 226.22; P<0.00001, I = 98%), especially in the peripheral nerve block(366.96 min, 95% CI, 154.19 to 579.74; P = 0.0007, I = 98%). Secondary outcomes showed ketamine could prolong the duration of sensory block(29.12 min, 95% CI, 10.22 to 48.01; P = 0.003, I = 96%) but no effect on the motor block(6.94 min, 95% CI,-2.65 to 16.53;P = 0.16, I = 84%), the onset time of motor and sensory block (motor onset time, -1.17 min, 95% CI, -2.67 to 0.34; P = 0.13, I = 100%; sensory onset time, -0.33 min, 95% CI,-0.87 to 0.20; P = 0.23, I = 96%) as well as the ketamine-related adverse effect(OR, 1.97, 95% CI,0.93 to 4.17;P = 0.08, I = 57%).
CONCLUSION
This study indicates that ketamine could be an ideal adjuvant to local anesthetics regardless of the types of anesthesia. Overall, the quality of the evidence is low.

Review
Nipple-sparing mastectomy is an alternative to skin-sparing mastectomy in select patients. Increasing evidence supports its use in the setting of breast cancer, however concerns still exist regarding oncological safety. The aim of this systematic review was to evaluate long-term oncological outcomes of patients who underwent nipple-sparing mastectomy for breast cancer. A systematic review of the literature was performed to evaluate oncological outcomes in patients with breast cancer who underwent nipple-sparing mastectomy. Five major databases (PubMed, Embase, Scopus, Web of Science and Cochrane) were searched. The review included all original articles published in English reporting long-term oncological outcomes. 2334 studies were identified. After applying inclusion and exclusion criteria, 17 retrospective studies involving 7107 patients were included. The indication for nipple-sparing mastectomy was invasive carcinoma in 6069 patients (85.4%) and in situ disease in 1038 (14.6%). Median follow up was 48 months (range 25-94). The weighted mean rates of local recurrence and recurrence involving the nipple-areola complex were 5.4% (0.9-11.9) and 1.3% (0-4.9), respectively. The weighted mean distant failure rate was 4.8% (1.5-23.0). Therapeutic nipple-sparing mastectomy is oncologically safe in select patients with breast cancer.

Meta-Analysis Review
Acellular dermal matrices (ADMs) are commonly used in prepectoral breast reconstruction. However, ADM is associated with high cost and potentially infection and seroma. Comparative studies on prepectoral reconstruction with and without ADM are limited to small, single-institution series. The purpose of this study was to perform a meta-analysis of prepectoral reconstruction with and without ADM. A systematic literature review was performed to identify studies comparing prepectoral reconstruction with and without ADM using PubMed, EMBASE, and Cochrane databases. Pooled rates of patient demographics and outcomes were analyzed. Meta-analytic effect size estimates were calculated for reconstructive complications in studies comparing reconstruction with and without ADM. In total, 515 reconstructions from four studies were included. Most cases were nipple-sparing mastectomies and utilized tissue-expander reconstructions. Meta-analysis demonstrated no significant difference in the rate of complications between cohorts with and without ADM. Short-term complications included reconstructive failure (1.2% in ADM cohort and 2.8% in no-ADM), seroma (1.2% and 8.3%, respectively), hematoma (1.2% and 2.1%), infection (4.7% and 4.2%), and mastectomy flap ischemia and/or necrosis (2.4% and 5.2%). Long-term complications included rippling (3.3% in ADM and 5.1% in no-ADM cohorts) and capsular contracture (6.8% and 3.4%, respectively). This meta-analysis demonstrated no difference in the rate of complications between cases with and without ADM. However, the outcomes data from no-ADM reconstruction mostly reflect robust mastectomy flaps. Surgeon discretion as informed by specific clinical scenarios should guide decisions regarding the use of ADM in prepectoral breast reconstruction.
