Effect of quilting on seroma formation in mastectomies: A meta-analysis

Complications of Superomedial Versus Inferior Pedicle Reduction Mammaplasty: A Systematic Review and Meta-Analysis

BACKGROUND

The superomedial pedicle reduction mammoplasty has gained popularity and is an important alternative approach for reduction mammoplasty, while the inferior pedicle reduction mammaplasty remains by far the most performed as it is considered to provide the best vascularization to the nipple-areola complex, allowing safe removal of large amount of redundant tissue. The authors conducted the first systematic review and meta-analysis in an attempt to declare the differences of the superomedial pedicle versus the inferior pedicle reduction technique by comparing the postoperative complications.

METHODS

PubMed, MEDLINE, and Cochrane Library for clinical studies were queried from inception to January 1, 2024. Review Manager Version 5.4 was used for this meta-analysis. A random effects model was applied to OR, and 95%CI were determined using the Mantel-Haenszel method. The I2 test was used to assess heterogeneity, and the Newcastle-Ottawa scale was used to assess the risk of bias in the nonrandomized studies.

RESULTS

Twelve observational comparative studies were included. The superomedial pedicle technique had a statistically lower rate of overall complications (OR 0.59, 95% CI 0.47-0.75; p < 0.0001) and delayed wound healing (OR 0.46, 95% CI 0.33-0.64; p < 0.00001) than the inferior pedicle technique. No significant differences in wound dehiscence, infection, seroma, hematoma, skin necrosis, fat necrosis, NAC necrosis, nipple sensation decrease or loss, asymmetry, hypertrophic scarring, and reoperation were noted.

CONCLUSIONS

Both two techniques are equally safe and reliable, while the superomedial pedicle technique resulted in a statistically lower rate of overall complications and delayed wound healing.

Prospective Study on Avoiding Seroma Formation by Flap Fixation After Modified Radical Mastectomy

INTRODUCTION

Seroma development after mastectomy is a common complication. Continued seroma causes increased outpatient visits, repeated aspirations, infection, delayed healing, delayed adjuvant therapy, and increased cost. Various treatments are being attempted to prevent and reduce seroma development. We examined the effects of flap fixation on seroma using absorbable sutures after modified radical mastectomy (MRM).

METHODS

The prospectively recorded data of patients who underwent surgery for breast cancer were analyzed retrospectively. 72 consecutive patients who underwent MRM were included in the study. Patients who underwent MRM in the same way by the same surgeon were divided into two groups: the group whose wound was closed by fixing the flap to the chest wall with an absorbable suture (group A), and the group whose wound was closed with the classical method (group B). The groups were compared in terms of seroma development, clinicopathological data, and early complications.

RESULTS

Drain removal time and the total amount of drained fluid in group A patients were significantly lower than drain removal time and the total amount of drained fluid in group B patients (P < .001). Similarly, the amount of aspirated seroma in the control examinations of group A patients was significantly lower than that in group B (P < .05). Group B needed re-aspiration significantly more than group A (P < .05).

CONCLUSIONS

Flap fixation with suture after MRM is a method that reduces seroma formation and the amount of drained fluid, enables early removal of the drain, prevents delay in starting adjuvant treatment, is more comfortable for the patient and physician, and is also inexpensive.

Current use of drains and management of seroma following mastectomy and axillary surgery: results of a United Kingdom national practice survey

PURPOSE

Up to 40% of the 56,000 women diagnosed with breast cancer each year in the UK undergo mastectomy. Seroma formation following surgery is common, may delay wound healing, and be uncomfortable or delay the start of adjuvant treatment. Multiple strategies to reduce seroma formation include surgical drains, flap fixation and external compression exist but evidence to support best practice is lacking. We aimed to survey UK breast surgeons to determine current practice to inform the feasibility of undertaking a future trial.

METHODS

An online survey was developed and circulated to UK breast surgeons via professional and trainee associations and social media to explore current attitudes to drain use and management of post-operative seroma. Simple descriptive statistics were used to summarise the results.

RESULTS

The majority of surgeons (82/97, 85%) reported using drains either routinely (38, 39%) or in certain circumstances (44, 45%). Other methods for reducing seroma such as flap fixation were less commonly used. Wide variation was reported in the assessment and management of post-operative seromas. Over half (47/91, 52%) of respondents felt there was some uncertainty about drain use after mastectomy and axillary surgery and two-thirds (59/91, 65%) felt that a trial evaluating the use of drains vs no drains after simple breast cancer surgery was needed.

CONCLUSIONS

There is a need for a large-scale UK-based RCT to determine if, when and in whom drains are necessary following mastectomy and axillary surgery. This work will inform the design and conduct of a future trial.

Quilting Suture Technique After Mastectomy: A Meta-Analysis

BACKGROUND

There is no level 1a evidence testing quilting suture (QS) technique after mastectomy on wound outcomes. The aim of this systematic review and meta-analysis evaluates QS and association with surgical site occurrences as compared to conventional closure (CC) for mastectomy.

METHODS

MEDLINE, PubMed, and Cochrane Library were systematically searched to include adult women with breast cancer undergoing mastectomy. The primary endpoint was postoperative seroma rate. Secondary endpoints included rates of hematoma, surgical site infection (SSI), and flap necrosis. The Mantel-Haenszel method with random-effects model was used for meta-analysis. Number needed to treat was calculated to assess clinical relevance of statistical findings.

RESULTS

Thirteen studies totaling 1748 patients (870 QS and 878 CC) were included. Seroma rates were statistically significantly lower in patients with QS (OR [95%CI] = .32 [.18, .57]; P < .0001) than CC. Hematoma rates (OR [95%CI] = 1.07 [.52, 2.20]; P = .85), SSI rates (OR [95%CI] = .93 [.61, 1.41]; P = .73), and flap necrosis rates (OR [95%CI] = .61 [.30, 1.23]; P = .17) did not significantly vary between QS and CC.

CONCLUSION

This meta-analysis found that QS was associated with significantly decreased seroma rates when compared to CC in patients undergoing mastectomy for cancer. However, improvement in seroma rates did not translate into a difference in hematoma, SSI, or flap necrosis rates.

Impact of Topical Epinephrine with Xylocaine on Drainage After Axillary Lymph Node Dissection: A Randomized Controlled Trial

INTRODUCTION

We evaluated the impact of topical epinephrine with xylocaine on drainage after axillary lymph node dissection.

METHODS

Fifty-two women were randomized into two groups, epinephrine with xylocaine drainage (ED) and conventional drainage group (CD). The amount of drainage, duration of drainage catheter, incidence of seroma formation and wound infection were noted.

RESULTS

The mean total drainage volume was less in ED group as compared to CD group (195 ml vs. 353 ml; p = .002). Drainage catheter was removed earlier in ED group as compared to CD group (5.07 + / - 0.99 days vs. 6.65 + / - 1.07 days; p = 0.0001). The incidence of seroma and wound infection was similar in two groups.

CONCLUSION

Topical epinephrine with xylocaine after axillary lymph node dissection results in significantly decreased drainage volume and duration of drainage.

Management of Postoperative Seroma: Recommendations Based on a 12-Year Retrospective Study

Introduction: Seroma formation is a serious postoperative complication. Since the management algorithms available in the literature are scarce, we aimed to analyze our experience with postoperative seroma in order to identify indicators for revisional surgery and propose recommendations for management. Methods: This retrospective study included all patients with postoperative seroma treated in a tertiary university hospital from 2008 to 2020. Patients’ demographics, medical history, and seroma treatment details were recorded and analyzed. Results: Overall, 156 patients were included: 41% were initially treated through needle aspiration, with 61% eventually undergoing surgical treatment for postoperative seroma. Comorbidities, such as heart failure and coronary heart disease, were significantly associated with an increased need for revisional surgery (p < 0.05). Both a duration of >40 days of repeated needle aspirations and drain re-insertions were significantly correlated with an increased risk for revisional surgery (p < 0.05). Conclusion: Patients requiring seroma aspiration should be counseled on surgical treatment sooner rather than later, as prolonged aspiration time (over 40 days) greatly increases the risk of surgical revision. Moreover, the reinsertion of a drain should only be used as a temporizing measure, at most, and patients requiring a drain to control the size of the seroma should promptly be scheduled for a surgical revision.
