INTRODUCTION In the realm of breast surgical interventions, a paramount emphasis is placed on achieving effective hemostatic control to mitigate the risk of bleeding complications. The occurrence of postoperative hematoma after mastectomy with immediate breast reconstruction ranges from 2% to 7%. Simultaneously, the rates of seroma vary, ranging from 1% to 80% in breast 1,2 Researchers and healthcare professionals have recently shown interest in the application of topical tranexamic acid (TXA) in breast surgery, recognizing its possible influence on hemostasis and postoperative results. Although the systemic administration of TXA has demonstrated effectiveness in minimizing blood loss, the specific ramifications of its topical application warrant further exploration. 4 TXA functions as a synthetic reversible competitive inhibitor targeting the lysine receptor present on This inhibitory action prevents the activation of plasmin, hindering its binding to the fibrin matrix and ultimately leading to the stabilization of the fibrin structure. 5 TXA has proven effective in reducing blood loss in a range of surgical procedures, including those related to the breast. 6 In the realm of breast reconstruction, standard practice includes the incorporation of drainage systems to mitigate potential complications such as seroma, hematoma, and the accumulation of excessive fluids during the healing phase. 7 However, prolonged elevation in drain output levels may extend the duration of drainage, thereby heightening the risk of infection and serving as a potential indicator for late complications. While there is a substantial body of existing research on the role of TXA in breast surgery, meta-analyses concentrated on its systemic administration. 4,9 To mitigate existing uncertainties, our meta-analysis aims to comprehensively investigate and synthesize the current corpus of evidence regarding the utilization of topical TXA in breast Through a meticulous assessment of pertinent research, our objective is to offer a more distinct and nuanced comprehension of the benefits and potential risks associated with the adoption of this methodology. This analysis is poised to offer practical insights for clinicians, addressing gaps in knowledge and facilitating evidence-based decision-making in breast surgical interventions.

Notably, this intervention does not demonstrate any discernible influence on the incidence of seroma, infection, thromboembolic events, or the duration until drainage removal. recognize that the investigation carried out by Bae in 2023 is a retrospective cohort study, which is prone to inherent challenges like selection bias, ascertainment bias, and confounding bias. Consequently, we performed an autonomous analysis, excluding the mentioned study. The results persisted in revealing statistical significance (MD -24. 38, p=0. Evaluating cumulative drainage output until extraction offers valuable insights into the observation of trends and changes over time, aiding in a comprehensive understanding of fluid dynamics and detecting potential later 22,23 When the data were combined, a noteworthy decline in cumulative drain output until removal was observed in the topical TXA group as opposed to the placebo group (MD 59. p<0. The contentious aspect of drain output volume revolves around the debate over whether the prolonged presence of elevated quantities could extend the duration of drainage and potentially elevate the risk of infection. AIn a 2022 study by Chua, sustained elevation in drain output, leading to delayed removal, emerged as an early indicator of impending complications. This implies that the link between delayed drain removal and complications is predictive rather than causative. 23 According to the statement, we performed statistical analyses of complications including the rate of hematoma, seroma and Upon consolidating data from all participants in the six studies examining hematoma formation, topical TXA application revealed a significantly diminished incidence compared to the control group . =0. Two RCTs by Ausen demonstrated reduced 24-hour drain output and lower hematoma rates, consistent with the earlier statement. However, a thorough investigation is needed to establish the significance of the relationship between drainage output volume and hematoma formation rates. Surgery type, intraoperative topical TXA administration details, including timing and dosage, varied significantly in the studies. All included research clearly outlined specific surgical procedures, with four concentrating on This detailed categorization ensures a comprehensive analysis of diverse surgical interventions related to our study's Within the subgroup analysis, we observed a reduced occurrence of hematoma formation in the groups administered with Comparison to Previous Literature No meta-analyses have been conducted on investigations comparing the application of topical TXA with a control group in breast A systematic review and meta-analysis conducted by Montroy in 2018 explored the effectiveness and safety of topical TXA across various surgical procedures, revealing a significant reduction in blood loss, particularly in orthopedic and cardiac surgery. However, the review only included one study on reduction mammoplasty, conducted by Ausen in 2015. Another study by Hyunh in 2023 indicated that TXA reduces hematoma formation. there is an overlap in results between topical and intravenous administration. Calpin 2023 reported the superiority of topical TXA over intravenous administration in reducing hematoma formation, but only three studies utilized topical TXA in the metaanalysis. 21 The outcomes from two randomized controlled trials conducted by Safran . and Yao . were omitted from the meta-analysis. Notably, the latter trial, which investigated the effectiveness of topical TXA in breast surgery, was the most recent among the studies As per Yao's findings in 2023, it was determined that the topical administration of TXA does not seem to reduce the occurrence of hematoma subsequent to breast reduction 18 The meta-analysis omitted analyses of post-operative drainage within the first 24 hours, cumulative drain output, and the duration until drain removal due to limited data Interpretation of Results This meta-analysis underscores a pivotal finding related to the efficacy of topical TXA in Our investigation demonstrates a substantial decrease in drain output during the first 24 hours when topical TXA is administered intraoperatively (MD -59. p<0.

This study found no significant effect of topical TXA in reducing thromboembolic event, capsular contracture and flap necrosis. The findings in this research align with a study that thromboembolic events linked to the application of topical TXA. 28,29 However, more study recording the rate of capsular contracture and flap necrosis are needed to draw more accurate This study found no significant associations with age. BMI, or tissue resection Variability in topical TXA dosages, timing, drain placement, surgeon experience, axillary clearance performance, and wound surface area may have influenced the metaanalysis outcomes. Additional research is needed to establish a consensus on the optimal concentration of topical TXA and the most efficacious timing for its administration in medical practice. Limitations This study has several limitations warrant It is crucial to acknowledge and address these constraints to enhance the overall understanding and interpretation of the research There was considerable variability in the baseline characteristics and the combined analysis of secondary outcomes, which diminished its overall significance for research The observed outcome might be attributed to potential residual confounding arising from unmeasured baseline characteristics that remain a factor beyond exclusion. Secondly, certain research investigations have incorporated interventions that influence the observed outcomes of topical administration of TXA. These interventions include the use of tumescent solution, epinephrine, triple antibiotic irrigation, postoperative thromboprophylaxis, and a compression protocol following surgical 3,15,16,19 Furthermore, the outcomes are significantly influenced by various factors, including the dosage of topical TXA, the specific timing of TXA administration, the placement of drainage systems and the skill level of the These elements collectively play crucial roles in shaping the overall impact on the results. Thirdly, our data synthesis reliability is constrained by varying study quality, assessed with the ROBINS-I and ROB2 tools, showing a range of risks from moderate to serious and low to some concern, respectively. Despite identified bias, these preliminary findings can generate hypotheses, prompting further research that mirrors real-world heterogeneity. Emphasizing the need for standardized reporting and advocating for additional research, this study contributes to existing literature, highlighting the importance of unraveling specific factors impacting outcomes in the studied context.
