Axillary Padding without Drainage after Axillary Lymphadenectomy - a Prospective Study of 299 Patients with Early Breast Cancer

Prevention of Seroma Formation and Its Sequelae After Axillary Lymph Node Dissection: An Up-to-Date Systematic Review and Guideline for Surgeons

INTRODUCTION

Seroma formation after axillary lymph node dissection (ALND) remains a troublesome complication with significant morbidity. Numerous studies have tried to identify techniques to prevent seroma formation. The aim of this systematic review and network meta-analysis is to use available literature to identify the best intervention for prevention of seroma after standalone ALND.

METHODS

A literature search was performed for all comparative articles regarding seroma formation in patients undergoing a standalone ALND or ALND with breast-conserving surgery in the last 25 years. Data regarding seroma formation, clinically significant seroma (CSS), surgical site infections (SSI), and hematomas were collected. The network meta-analysis was performed using a random effects model and the level of inconsistency was evaluated using the Bucher method.

RESULTS

A total of 19 articles with 1962 patients were included. Ten different techniques to prevent seroma formation were described. When combining direct and indirect comparisons, axillary drainage until output is less than 50 ml per 24 h for two consecutive days results in significantly less CSS. The use of energy sealing devices, padding, tissue glue, or patches did not significantly reduce the incidence of CSS. When comparing the different techniques with regard to SSIs, no statistically significant differences were seen.

CONCLUSIONS

To prevent CSS after ALND, axillary drainage is the most valuable and scientifically proven measure. On the basis of the results of this systematic review with network meta-analysis, removing the drain when output is < 50 ml per 24 h for two consecutive days irrespective of duration seems best. Since drainage policies vary widely, an evidence-based guideline is needed.

Retrospective Evaluation of the Effectiveness of a Synthetic Glue and a Fibrin-Based Sealant for the Prevention of Seroma Following Axillary Dissection in Breast Cancer Patients

Introduction: Seroma formation represents one of the most frequent postoperative complications of axillary dissection in breast cancer (BC) patients. We aimed to retrospectively explore the effectiveness of the intraoperative use of a synthetic cyanoacrylate glue (specifically Glubran®2) vs. the intraoperative use of a fibrin sealant (specifically Tisseel) in reducing seroma formation compared to the use of nonsealant in BC patients who underwent breast surgery and axillary dissection. Materials and Methods: We conducted a retrospective, monocentric observational study on BC patients who underwent axillary dissection associated with breast surgery. The axillary dissection was completed with the application of a closed suction drain and was preceded by the application of either Glubran®2 glue or Tisseel sealant or nonsealant. We analyzed the quantity of serum drained in the first 3 postoperative days, length of hospitalization, days of permanence of axillary drain, seroma development, and presence of postoperative infection signs. Results: Forty-one BC patients were considered. Based on the device used during the surgical treatment, the patients were divided into three groups: group A (17 patients), to whom suction axillary drain was applied; group B (7 patients), to whom Tisseel and axillary suction drain were applied; and group C (17 patients), to whom Glubran®2 and axillary suction drain were applied. Among the three groups, we did not find significant differences in terms of amount of serum drained in the first 3 postoperative days, length of hospitalization, and incidence of seroma. Group C maintained the axillary drain in a significantly lower number of days compared to the other two groups (p = 0.02); it also had a lower incidence of postoperative infections (6%) compared to group A (23%) and group B (57%) (p = 0.02). Conclusions: We did not find any evidence that the use of surgical glues may reduce the formation of seroma following axillary dissection in BC patients. Nevertheless, the use of cyanoacrylate glue in association with closed suction axillary drain seems to contribute to the reduction in days of axillary drain permanence and of postoperative infections, which are known factors delaying the schedule of any adjuvant oncological therapies.

Seroma in breast surgery: all the surgeons fault?

BACKGROUND

Despite a trend for less radical surgical approaches in breast cancer due to better understanding of tumour biology and new treatment options such as neoadjuvant chemotherapy (NAC) and intra-operative radiotherapy (IORT), seroma production remains one of the main surgical side effects that can result in prolonged recovery, delay of radiotherapy and patient discomfort. The aim of this study is to provide an update on risk factors for seroma production after breast cancer surgery considering the latest treatment options.

METHODS

A retrospective analysis of seroma production in primary breast cancer patients treated between 01.01.2010 and 31.12.2014 at the Breast Cancer Centre, University Hospital Ulm, was performed. Patients with previous breast/axillary surgery or more than one intervention were excluded. Seroma formation was measured using wound drains placed in breast and axilla.

RESULTS

In total, 581 patients met the inclusion criteria. Median age at diagnosis was 60 years, and median BMI 25.6 kg/m². 60 (10.3%) patients had a mastectomy, 175 (30.1%) patients received IORT, and 72 (12.4%) patients received NAC. Median amount of seroma production was 82.5 ml (range 0-3012.5 ml). Multivariate analysis revealed that most of the observed variation in seroma production was due to type of surgery (mastectomy vs. breast conserving), length of surgery and number of removed lymph nodes. Both NAC and IORT explained a significant but very small amount of the observed variation in seroma production.

CONCLUSION

The most important factors for seroma production are extent and duration of breast surgery.

Use of Low-Thrombin Fibrin Sealant Glue After Axillary Lymphadenectomy for Breast Cancer to Reduce Hospital Length and Seroma

BACKGROUND

Axillary lymphadenectomy for primary breast cancer produces a non-negligible rate of postoperative lymphorrhea, prolonged hospital stays, and multiple seroma punctures. We evaluated the impact of low-thrombin fibrin sealant glue on surgical wounds in patients undergoing axillary lymph node dissection for breast cancer.

METHODS

We conducted an observational study of 149 patients who underwent axillary lymphadenectomy for primary breast cancer between January 2014 and December 2015. Data were obtained from 2 successive prospective studies. The hospital stay length and morbidity (seromas, punctures) were compared between 2 groups: patients who had padding sutures and low-thrombin fibrin sealant glue without drainage (n = 49) and patients with drainage alone (n = 100). Hospital costs were assessed from the hospital perspective.

RESULTS

The mean hospital stay length was shorter in the fibrin sealant group (2.6 vs. 4.7 days; P < .001). Seroma magnitude and punctures were similar in patients treated with fibrin sealant compared with patients with drainage alone. The rate of needle aspiration for seroma was similar irrespective of whether or not a drain or fibrin sealant was used (30.6% vs. 33.0%, P = .77).

CONCLUSION

Low-thrombin fibrin sealant glue does not significantly reduce the amount of fluid produced in the axilla after breast surgery; however, its systematic use may help reduce hospital stays and costs.

Comparison of seroma production in breast conserving surgery with or without intraoperative radiotherapy as tumour bed boost

INTRODUCTION

One of the most common complications in breast conserving surgery is seroma formation. The origin of seroma formation remains unclear. While intraoperative radiotherapy (IORT) has been shown to be an alternative to whole breast irradiation, the influence on seroma production is unclear. Therefore, this analysis compares seroma production in patients with breast conserving surgery with or without IORT as tumour bed boost during breast conserving surgery.

METHOD

A retrospective analysis of seroma production in patients with nodal-negative (pN0sn) pT1/2 primary breast cancer treated between September 2010 and October 2013 at the Breast Cancer Centre, University Hospital Ulm was performed. Patients with neoadjuvant chemotherapy, previous breast/axillary surgery or more than one intervention were excluded. IORT was applied as a tumour bed boost with 50-kV X-rays (Intra beam(®)) delivering 9 Gy at the applicator surface. Seroma formation was measured using wound drains placed in breast and in axilla.

RESULTS

Data of 152 patients (99 -IORT; 53 +IORT) were available for analysis. No significant differences between patients with or without IORT with regard to seroma production and number of days until drain removal were found (all p > 0.05).

CONCLUSION

Patients with IORT encountered no increased seroma production and removal of the drains was not delayed compared to patients with breast conserving surgery only. Our results indicate that IORT does not increase the seroma production compared to surgery alone.

Techniques in the prevention and management of seromas after breast surgery

Seromas are the most frequent complications following breast surgery, resulting in significant discomfort and morbidity with possible delays in commencing adjuvant therapies. Varied clinical practices exist in the techniques employed to prevent and manage seromata. This article assesses published literature on the techniques employed in prevention of seroma formation following breast surgery, evaluating the different methodologies used. Although prevention is the best strategy, seromata remain problematic and we consider their management. The principle findings were that prevention is key to the management of seromata. Methods employed to prevent seromata include suction drainage, shoulder immobilization, quilting sutures, fibrin sealants and innovative measures of managing the axilla, among others. The evidence demonstrated that a combination of quilting and drains significantly reduces the incidence and volumes of seromata. These effects are sustained by minimizing use of electrocautery, alongside increasing frequencies of axillary sentinel lymph node biopsies and node sampling. The efficacy data on fibrin sealants is inconclusive and consequently should not be routinely used alone or accompanied by quilting sutures. Clinically significant seromas deemed 'symptomatic' by patients and complicating infected seromas should be aspirated. There are limited data on the recommended treatment of established seromas with a paucity of high-quality studies and further research involving randomized trials are indicated.

Quilting Sutures Reduces Seroma in Mastectomy

BACKGROUND

Drainage duration and seroma formation occurring after mastectomy with or without axillary surgery lengthens hospitalization and delays adjuvant treatment. The aim of the study was to evaluate the effect of quilting in the prevention of seroma after mastectomy for breast cancer.

PATIENTS AND METHODS

Eighty-two breast cancer patients about to undergo mastectomy with or without axillary surgery lymphadenectomy were enrolled in the study. We conducted an observational comparison between 41 patients in whom quilting with closed suction drainage was used and 41 patients in whom drainage only was used.

RESULTS

The mean drained volume was significantly lower in the quilting group compared with the control group on days 1 and 2 (day 1: 107.1 mL vs. 156.5 mL; P = .02; day 2: 108.4 mL vs. 162.8 mL; P = .01). The mean drainage period was shorter in the quilting group (4.6 vs. 5.3 days; P = .046). There were fewer needle aspirations for seroma in the padding group (n = 14, 34.1% vs. n = 24, 58.5%; P = .03).

CONCLUSION

The use of padding after mastectomy seems to reduce seroma formation, volume drained, and length of drainage time.

Should a drain be placed in early breast cancer surgery?

BACKGROUND

The current surgical debate has led to a reduction in the extent of surgery performed and thereby to a reduced occurrence of surgical trauma and, over the recent years, reduced seroma formation. This reduction in surgical procedures calls the need for a drain into question.

METHOD

Using Google Scholar and the National Library of Medicine (PubMed), a literature review was performed on systematic reviews and meta-analyses regarding breast cancer surgery ± axillary dissection. Additionally, randomized trials for the time period after the last systematic review were included and evaluated according to the Jadad score.

RESULTS

The search returned 5 systematic reviews, in which a total of 1,075 patients were included (537 cases and 538 controls). Since the last review, no prospective randomized trial meeting the inclusion criteria has been published. The current reviews conclude that insertion of a drain is associated with a longer hospital stay and reduced seroma formation. The data regarding wound infection and drain insertion is inconclusive. The omission of a drain is associated with early discharge, reduced postsurgical pain, and early mobilization, but also with an increase in outpatient seroma aspirations.

CONCLUSION

The omission of a drain is possible in early breast cancer surgery (wide local excision and sentinel node biopsy) with adequate surgical techniques and instruments.

The influence of the initiation of an exercise programme on seroma formation and dehiscence following breast cancer surgery

AIMS AND OBJECTIVES

To verify whether early (first post-operative day) or late initiation (after removal of the continuous suction drain) of a functional rehabilitation exercise programme influences the incidence of seroma formation and dehiscence for women after breast cancer surgery.

BACKGROUND

Benefits of early implementation of an exercise programme initiated with women in the first days following breast cancer surgery are widely known. However, the safe initiation of the exercises is still a controversial issue and some authors correlate early initiation of the exercises with an increase in seroma formation.

DESIGN

A prospective, randomised, controlled clinical trial.

METHODS

Seventy-seven women were randomly assigned to initiate the programme on post-operative day 1 (early group = 40) or after removal of the drain (late group = 37) and were monitored until the 45th post-operative day. Patients in the early group were instructed to perform the exercises daily at home, beginning on post-operative day 1, while those of the late group began the exercises after the drain was removed. The assessment for seroma formation and dehiscence was performed on post-operative days 7 and 45.

RESULTS

There was no statistically significant difference regard to seroma formation between early group and late group. Also there was no association between the presence of dehiscence and early exercises.

CONCLUSION

The early initiation of the exercises for women, following breast cancer surgery, constitutes a safe practice for the rehabilitation. However, these findings need to be further explored and confirmed in a larger sample.

RELEVANCE TO CLINICAL PRACTICE

Studies showing evidence that early functional rehabilitation process is a safe practice for women having surgery for breast cancer, as well as the present research, are of interest to health professionals who care for these patients and contribute to the wider global clinical community.

Wound drainage after axillary dissection for carcinoma of the breast

BACKGROUND

Axillary dissection is commonly performed for breast carcinoma. It is uncertain whether insertion of a drain reduces complication rates.

OBJECTIVES

To assess the effects of wound drainage after axillary dissection for breast carcinoma on the incidence of postoperative seroma formation. Secondary outcome measures include the incidence of infection and length of hospital stay.

SEARCH METHODS

We searched the Cochrane Wound and Breast Cancer Group's Specialised Registers (22 February 2013), MEDLINE (1950 to 22 February 2013), EMBASE (1966 to 22 February 2013), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov (22 February 2013) for all prospectively registered and ongoing trials (22 February 2013). Reference lists of included studies were handsearched by two independent review authors to look for additional eligible trials.

SELECTION CRITERIA

All randomised controlled trials (RCTs) comparing wound drainage versus no wound drainage in individuals after axillary dissection for the treatment of breast carcinoma were included. All disease stages were considered. Breast-conserving surgery and mastectomy were considered. Patients undergoing sentinel node biopsy without axillary dissection were not included. No limits were applied to language or study location. Two review authors independently determined the eligibility of each study.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data for each included study using a predesigned data extraction proforma and assessed risk of bias using The Cochrane Collaboration's 'Risk of bias' tool. Discrepancies were resolved by consensus discussion with a third review author. Dichotomous variables were analysed using a Mantel-Haenszel model to produce odds ratios (ORs). Continuous variables were analysed using an inverse variance model to produce a mean difference (MD).

MAIN RESULTS

Seven RCTs including 960 participants were identified. The quality of trials was generally low, with several studies at risk of selection bias, and no studies used blinding during treatment or outcome assessment. There was a high level of statistical variation between the studies, which therefore reduces the reliability of the evidence. The OR for seroma formation was 0.46 (95% confidence interval (CI) 0.23 to 0.91, P = 0.03) in favour of a reduced incidence of seroma in participants with drains inserted. There was no significant difference in infection rates between drainage and no drainage groups (OR = 0.70; 95% CI 0.44 to 1.12, P = 0.14). The mean difference in length of hospital stay, reported in four trials consisting of 600 participants, was 1.47 days greater in the drained population (95% CI 0.67 to 2.28, P = 0.0003). A mean difference of 0.79 fewer postoperative seroma aspirations was found in the drained population (95% CI 1.23 to 0.35 fewer, P = 0.0004) in two trials including 212 participants. No significant difference in volume of seroma aspirations was reported (MD -19.44, 95% CI -59.45 to 20.57, P = 0.34) in three trials including 519 participants. No significant difference in the incidence of lymphoedema was noted (OR 2.31 favouring no drainage, 95% CI 0.47 to 11.37, P = 0.30), with only six instances reported in three trials of 360 participants, nor was any significant difference in the incidence of haematoma observed (OR 1.68, 95% CI 0.33 to 8.51, P = 0.53), with only five instances reported in two trials of 314 participants.

AUTHORS' CONCLUSIONS

There is limited quality evidence that insertion of a drain following axillary lymphadenectomy reduced the odds of developing a seroma and reduced the number of post-operative seroma aspirations. These benefits should be balanced against an increased length of hospital stay in the drained population.

Breast cancer surgery without suction drainage: the impact of adopting a 'no drains' policy on symptomatic seroma formation rates

AIM

To determine the effect of a 'no drains' policy on seroma formation and other complications in women undergoing breast cancer surgery.

MATERIALS AND METHODS

Before May 2010 drains were routinely used in our unit following mastectomy ± axillary surgery and axillary lymph node dissection (ALND) ± wide local excision (WLE). Since then, a 'no drains' policy has been adopted. Data was collected prospectively between 01/12/06 and 30/11/11 to compare symptomatic seroma, wound infection, re-admission and re-operation rates in women treated with a drain and those without.

RESULTS

596 women were included in the study. 247 women underwent modified radical mastectomy (MRM) and ALND (Group 1), 184 MRM ± sentinel lymph node biopsy (SLNB)/axillary node sampling (ANS) (Group 2) and 165 ALND ± WLE (Group 3). In group 1, 149 had a drain, in group 2, 62, and in group 3, 50. Within each group, the presence or absence of a drain did not significantly affect the rate of symptomatic seroma, number of aspirations performed, wound infection rates or the incidence of complications requiring re-admission. Having a drain was associated with lower volumes of seroma aspirated. In all three groups, the presence of a drain was associated with a longer hospital stay (p < 0.001).

CONCLUSION

This study suggests that MRM ± ALND/SLNB/ANS and ALND ± WLE can be performed without the use of suction drains without increasing seroma formation and other complication rates. Adopting a 'no-drains' policy may also contribute to earlier hospital discharge.
