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.

Review
PURPOSE
Mastectomy in women is perceived as losing feminine identity and reducing sexual attraction. The aim of this review is to explore the perception and impacts of mastectomy on Iranian women with breast cancer on their sexuality and body image.
METHODS
The review used a systematic literature search that followed the guidelines of the Joanna Briggs Institute (JBI). The data sources PubMed, Scopus, Web of Science, Google Scholar, SID, ProQuest, MEDLINE, and CINAHL (via the EBSCOhost) were systematically searched. Quality appraisal, data extraction, and findings from the included studies were pooled using meta-aggregation with the Qualitative Assessment and Review Instrument (JBI-QARI).
RESULTS
Eight studies involving 163 women aged from 31 to 65 years, who had mastectomy, were included. A total of 31 findings were extracted and were aggregated into 4 categories and then further grouped into two synthesized findings: (1) fear of losing spouse's sexual monopoly and (2) overcoming the challenges of losing femininity.
CONCLUSIONS
This review found even in Muslim countries such as Iran women's breasts are perceived as sexually attractive, and changes in body shape can lead to subsequent challenges in marital relationships.

Meta-Analysis Review
BACKGROUND
Native skin flap necrosis is a potentially devastating complication following skin-sparing or nipple-sparing mastectomy with a reported incidence of as high as 30%. Treatment depends on the depth and extent of tissue necrosis and can range from dressings to surgical debridement and further reconstruction. This can have implications on patient physical and psychological wellbeing as well as cost of treatment. This study aims to identify and appraise cost-effective non-surgical adjuncts for the prevention of native skin flap necrosis.
METHODS
A systematic review was performed using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement and structured around existing recommended guidelines. A search of MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature and ClinicalTrials.gov was performed with the medical subject headings 'mastectomy' and 'flap necrosis'. After exclusion, 12 articles were selected for review and analysed.
RESULTS
A total of 8439 mastectomies were performed on 7895 patients. Preventative non-surgical adjuncts that demonstrated statistically significant reduction in mastectomy flap necrosis included topical nitroglycerin ointment (P = 0.000), closed-Incision negative pressure wound therapy (P = 0.000), topical dimethylsulfoxide ointment (P = 0.03), oral cilostazol (P = 0.032), and local heat pre-conditioning (P = 0.047).
CONCLUSIONS
This study identifies multiple adjuncts that may aid in preventing mastectomy skin flap necrosis, especially in high-risk patients. Further studies could aim to define standardized protocols and compare the various adjuncts in different circumstances.

BACKGROUND
Improving patient care and safety requires high-quality evidence. The objective of this study was to systematically review the existing evidence for patient safety (PS) and quality improvement initiatives in breast reconstruction.
METHODS
A systematic review of the published plastic surgery literature was undertaken using a computerized search and following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Publication descriptors, methodological details, and results were extracted. Articles were assessed for methodological quality and clinical heterogeneity. Descriptive statistics were completed, and a meta-analysis was considered.
RESULTS
Forty-six studies were included. Most studies were retrospective (52.2%) and from the third level of evidence (60.9%). Overall, the scientific quality was moderate, with randomized controlled trials generally being higher quality. Studies investigating approaches to reduce seroma (28.3% of included articles) suggested a potential benefit of quilting sutures. Studies focusing on infection (26.1%) demonstrated potential benefits to prophylactic antibiotics and drain use under 21 days. Enhanced recovery after surgery protocols (10.9%) overall did not compromise PS and was beneficial in reducing opioid use and length of stay. Interventions to increase flap survival (10.9%) demonstrated a potential benefit of nitroglycerin on mastectomy skin flaps.
CONCLUSIONS
Overall, studies were of moderate quality and investigated several worthwhile interventions. More validated, standardized outcome measures are required, and studies focusing on interventions to reduce thromboembolic events and bleeding risk could further improve PS.

Review
Risk-reducing surgeries decrease the risk of developing breast cancer by 95%. But this type of surgery can be life-changing. This systematic review analyzed anxiety/depressive symptomatology, body image and quality of life on BRCA1/2 mutation carriers with or without a previous oncological history who have undergone risk-reducing mastectomy. PRISMA method was used to conduct this review. The initial search identified 234 studies. However, only 7 achieved the inclusion criteria. No statistically significant differences were found in terms of anxious symptomatology. One study found that depressive symptomatology had increased significantly in women without previous oncological history at the long-term follow-up measure. Women who underwent bilateral risk-reducing mastectomy and implant-based breast reconstruction tended to be satisfied with their body image/cosmetic outcome. No differences were reported at long-term follow-ups, independently of the surgery performed.

Review
OBJECTIVE
To explore men's experiences of their partner's altered physique and body image as a result of mastectomy and subsequent reconstructive surgeries.
DESIGN
A systematic review of qualitative and mixed-methods studies.
DATA SOURCES
Ovid, EBSCOhost, Web of Science, SCOPUS and ASSIA ProQuest databases were searched using 1) truncations of breast cancer, hereditary breast cancer and BRCA 2) words relating to partner relationships; spouse, husband, partner, men and couple 3) breast cancer surgeries; mastectomy, prophylactic mastectomy and breast reconstruction and 4) body image.
REVIEW METHOD
Methodological rigour was quality assessed.
RESULTS
A total of 756 citations were retrieved. Seventeen articles remained following the removal of duplicates, papers unrelated to breast cancer, male breast cancer, papers that excluded men's experiences of their partner's breast cancer and altered body image. Thematic analysis was applied and produced five themes: experiences of the altered body, communication, impact on relationship, information giving and recommendations.
CONCLUSION
Men indicated that perceptions of their partner's altered physique and body image, following mastectomy, was secondary to their health. Some men were distressed by their partner's bodily alterations leading to highly complex and emotive coping mechanisms. Men found talking to their partner about physique and body image challenging. Closed communication, however, often led to conflict and poor psychological well-being in both partners. To help prepare for the changes to their partner's body, men desired tailored information. Effective information giving contributes to effective coping strategies helping men to better support their partner affected or at risk from breast cancer, leading to enhanced psychological and emotional well-being in couples.

Review
BACKGROUND
The clinical effectiveness of treating ipsilateral multifocal (MF) and multicentric (MC) breast cancers using breast-conserving surgery (BCS) compared with the standard of mastectomy is uncertain. Inconsistencies relate to definitions, incidence, staging and intertumoral heterogeneity. The primary aim of this systematic review was to compare clinical outcomes after BCS versus mastectomy for MF and MC cancers, collectively defined as multiple ipsilateral breast cancers (MIBC).
METHODS
Comprehensive electronic searches were undertaken to identify complete papers published in English between May 1988 and July 2015, primarily comparing clinical outcomes of BCS and mastectomy for MIBC. All study designs were included, and studies were appraised critically using the Newcastle-Ottawa Scale. The characteristics and results of identified studies were summarized.
RESULTS
Twenty-four retrospective studies were included in the review: 17 comparative studies and seven case series. They included 3537 women with MIBC undergoing BCS; breast cancers were defined as MF in 2677 women, MC in 292, and reported as MIBC in 568. Six studies evaluated MIBC treated by BCS or mastectomy, with locoregional recurrence (LRR) rates of 2-23 per cent after BCS at median follow-up of 59·5 (i.q.r. 56-81) months. BCS and mastectomy showed apparently equivalent rates of LRR (risk ratio 0·94, 95 per cent c.i. 0·65 to 1·36). Thirteen studies compared BCS in women with MIBC versus those with unifocal cancers, reporting LRR rates of 2-40 per cent after BCS at a median follow-up of 64 (i.q.r. 57-73) months. One high-quality study reported 10-year actuarial LRR rates of 5·5 per cent for BCS in 300 women versus 6·5 per cent for mastectomy among 887 women.
CONCLUSION
The available studies were mainly of moderate quality, historical and underpowered, with limited follow-up and biased case selection favouring BCS rather than mastectomy for low-risk patients. The evidence was inconclusive, weakening support for the St Gallen consensus and supporting a future randomized trial.

Meta-Analysis
BACKGROUND
There is limited evidence available in the literature with regard to the complication profile of mastectomy and immediate prosthetic reconstruction in augmented patients.
OBJECTIVES
The aim of this systematic review and meta-analysis was to compare postoperative complications between women with vs without prior augmentation undergoing skin- or nipple-sparing mastectomy and immediate prosthetic reconstruction.
METHODS
A systematic search was conducted in February 2020 for studies comparing women with vs without prior augmentation undergoing skin- or nipple-sparing mastectomy and immediate prosthetic reconstruction with documentation of postoperative complications. Outcomes analyzed included early, late, and overall complications. Pooled odds ratios (ORs) with 95% CIs were obtained through meta-analysis.
RESULTS
Our meta-analysis, which included 6 studies comparing 241 breasts with prior augmentation and 1441 without, demonstrated no significant difference between the 2 groups in rates of early (36.7% vs 24.8%: OR, 1.57; 95% CI, 0.94-2.64; P = 0.09), late (10.1% vs 19.9%: OR, 0.53; 95% CI, 0.06-4.89; P = 0.57), and overall complications (36.5% vs 31.2%: OR, 1.23; 95% CI, 0.76-2.00; P = 0.40). Subgroup analysis showed a significantly higher rate of hematoma formation in the augmented group (3.39% vs 2.15%: OR, 2.68; 95% CI, 1.00-7.16; P = 0.05), but no difference in rates of seroma, infection, mastectomy skin flap necrosis, and prosthesis loss.
CONCLUSIONS
Our meta-analysis suggests that prior augmentation does not significantly increase overall postoperative complications in women undergoing skin- or nipple-sparing mastectomy and immediate prosthetic reconstruction. However, the significantly higher rate of hematoma formation in augmented patients warrants further investigation and preoperative discussion.
