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

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.

Seroma control in axillary lymphadenectomy with Glubran 2® without drain. Multicenter, prospective, randomized, clinical trial. GALA-ND study (Glubran, Axillary Lymphadenectomy, Ambulatory, No Drain)

BACKGROUND

Seroma after breast cancer surgery is a frequent entity; therefore, different products have been described in literature with the aim to reduce it. The most studied ones have been the sealants products, being tested with aspirative drains. Symptomatic seroma represents the 19% after axillary lymphadenectomy without drains. The aim of this study is to analyze the effect of a sealant in the seroma control after axillary lymphadenectomy without drains and identify the risk factors related to symptomatic seroma.

METHODS

This is a prospective, multicenter, international, and randomized clinical trial. Patients undergoing conservative surgery and axillary lymphadenectomy for breast cancer will be randomized to control group (lymphadenectomy without sealant) or interventional group (lymphadenectomy with sealant Glubran 2®). In any of the study groups, drains are placed. Patients who received neoadjuvant treatment are included. Measurements of the study outcomes will take place at baseline; at 7, 14, and 30 days post-surgery; and at 6-12 months. The primary outcome is symptomatic seroma. Secondary outcomes are seroma volume, morbidity, quality of life, and lymphedema.

DISCUSSION

Several studies compare the use of sealant products in axillary lymphadenectomy but generally with drains. We would like to demonstrate that patients who underwent axillary lymphadenectomy could benefit from an axillary sealant without drains and reduce axillary discomfort while maintaining a good quality of life. Assessing the relationship between axillary volume, symptoms, and related risk factors can be of great help in the control of seroma in patients who received breast cancer surgery.

Lymph node metastasis in cancer progression: molecular mechanisms, clinical significance and therapeutic interventions

Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. In recent years, with the updates in both basic and clinical studies on LNM and the application of advanced medical technologies, much progress has been made in the understanding of the mechanisms of LNM and the strategies for diagnosis and treatment of LNM. In this review, current knowledge of the anatomical and physiological characteristics of LNs, as well as the molecular mechanisms of LNM, are described. The clinical significance of LNM in different anatomical sites is summarized, including the roles of LNM playing in staging, prognostic prediction, and treatment selection for patients with various types of cancers. And the novel exploration and academic disputes of strategies for recognition, diagnosis, and therapeutic interventions of metastatic LNs are also discussed.

Clinical and cost outcomes of a polyethylene glycol (PEG)-coated patch versus drainage after axillary lymph node dissection in breast cancer: results from a multicentre randomized clinical trial

BACKGROUND

The aim of this study was to compare the clinical outcomes between breast cancer patients who underwent axillary lymph node dissection with postoperative management using a polyethylene glycol-coated patch versus axillary drainage. The direct costs associated with both postoperative management strategies were also evaluated.

METHODS

This was a multicentre RCT in women with breast cancer who underwent axillary lymph node dissection (ClinicalTrials.gov identifier: NCT04487561). Patients were randomly assigned (1 : 1) to receive either drainage or a polyethylene glycol-coated patch as postoperative management. The primary endpoints were the need for an emergency department visit for any event related to the surgery and the rate of seroma development.

RESULTS

A total of 227 patients were included , 115 in the patch group (50.7 per cent) and 112 (29.4 per cent ) in the drainage group. The incidence of emergency department visits was significantly greater for patients with drainage versus a polyethylene glycol-coated patch (incidence rate difference 26.1 per cent, 95 per cent c.i. 14.5 to 37.7 per cent; P < 0.001). Conversely, the seroma rate was significantly higher in the polyethylene glycol-coated patch group (incidence rate difference 22.8 per cent, 95 per cent c.i. 6.7 to 38.9 per cent; P < 0.0055). Compared with drainage, using a polyethylene glycol-coated patch resulted in cost savings of €100.41 per patient. An incremental cost-effectiveness ratio analysis found that drainage was associated with an incremental cost-effectiveness ratio of €7594.4 for no need for hospital admission and €491.7 for no need for an emergency department visit.

CONCLUSION

Compared with patients who received drainage after axillary lymph node dissection, the use of a polyethylene glycol-coated patch resulted in a higher rate of seroma, but a lower number of postoperative outpatient or emergency department visits and thus a reduction in overall costs.

The efficacy of oxidized regenerated cellulose (SurgiGuard®) in breast cancer patients who undergo total mastectomy with node surgery: A prospective randomized study in 94 patients

Background

Seromas frequently develop in patients who undergo total mastectomy with node surgery. We aimed to prospectively explore whether use of oxidized regenerated cellulose (ORC, SurgiGuard^®) affects seroma formation after total mastectomy with node surgery (sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND)).

Materials and methods

Ninety four breast cancer patients were enrolled in the study who underwent total mastectomy with ALND or SLNB. The patients were randomized into two groups, one treated with ORC plus closed suction drainage and the other with closed suction drainage alone.

Results

Mean drainage volume was slightly lower in the ORC group on postoperative day 1 (123 ± 54 vs 143 ± 104 ml), but was slightly higher at all other time points; however, these differences were not significant. Mean total drainage volume in patients treated with ORC plus drainage did not differ from that of patients treated with drainage alone (1134 ± 507 ml vs 1033 ± 643 ml, P = 0.486).

Conclusions

Use of ORC (SurgiGuard^®) did not significantly alter the risk of seroma formation.

Randomised controlled study of seroma rates after mastectomy with and without quilting the skin flap to pectoralis muscle

Aims

The aim of this study was to determine whether seroma formation was affected by reduction of the potential dead space with the flap fixation method and obliteration of the axillary region in patients with breast cancer who underwent either mastectomy and axillary lymph node dissection or sentinel lymph node biopsy. A total of 105 patients with breast cancer were divided into two groups according to wound closure patterns.

Patients and Methods

The operating time, postoperative pain and complications, time to drain removal, seroma formation, amount of fluid aspirated and number of aspirations were recorded prospectively.

Results

No significant difference was found between groups in the rates of seroma development (P = 0.7), complication rates (P = 0.6), time to drain removal (P = 0.5), length of hospital stay (P = 0.3) or numbers of aspiration (P = 0.7). The operating time for fixation was determined to be longer than that of the classic procedure (P = 0.02).

Conclusions

Reducing potential dead space with flap fixation and obliteration of the axillary region may be useful in decreasing the development of seroma in patients who have undergone mastectomy because of breast cancer. However, surgical technique must be careful, and appropriate patient follow-up must be conducted.

Varying Negative Pressure Wound Therapy Acute Effects on Human Split-Thickness Autografts

Over 6.5 million people in the United States suffer from traumatic, burn, acute, and chronic wounds yearly. When reconstruction is required, split and full-thickness autografts are a first line of treatment intervention. Negative pressure wound therapy (NPWT) is gaining traction as an adjunct modality to improve graft survival, yet the specifics on what settings to apply topically over the graft is unsubstantiated and associated with morbidities. This study was performed in an effort to understand initial changes in wound and graft healing with a long-term goal of surface pressure optimization. Excess skin from elective procedures from six human subjects was trimmed to 0.012 inch in order represent a split-thickness autografts. These grafts were treated continuously with either -75 mm Hg (n = 4), -125 mm Hg (n = 4), or no pressure (n = 4) for 3 hours. Six skin grafts were treated with no sponge or pressure control (n = 6). RNAseq was performed on all treatment groups and compared with no pressure control. Significant gene expression changes with a subset focusing on inflammatory, cellular/extracellular matrix proliferation and angiogenic mediators and having greater than 2-fold were confirmed with immunohistochemistry staining. There are 95 significant gene transcription differences among all treatment groups. NPWT leads to significantly increased gene expression of FGFR1, ET-1, and 22 Keratin proteins. Between -75 and -125 mm Hg groups, there are 19 significant gene changes. Proinflammatory genes S100A8 and Tenacin C (TNC) demonstrate an 8.8- and 9.1-fold change, respectively, and is upregulated in -125 mm Hg group and downregulated in -75 mm Hg group. Fibrinogen genes fibrinogen gamma chain and fibrinogen alpha chain had respective log2-fold changes of -7.9 and -7.4 change between treatment groups and were downregulated in -125 mm Hg group and upregulated in -75 mm Hg group. There are varying effects of surface pressures on human split-thickness autografts during the imbibition time period. NPWT may improve cellular migration, proliferation, and angiogenesis over controls. Human skin grafts respond differently to -125 and -75 mm Hg within 3 hours of NPWT treatment. The results suggest -75 mm Hg leads to less inflammation and increased fibrinogen production compared with the -125 mm Hg group, at least initially. Reducing "time to heal" with NPWT is critical to successful outcomes and quality of life within young patients who often experience pain/discomfort when treated at the current standard pump settings. The results from this study and continued investigation may quickly translate to the clinical setting by finding the ideal pressure setting utilized in an effort to reduce NPWT length of treatment, improve patient comfort, satisfaction, and psychosocial well-being.

Conventional suture with prolonged timing of drainage is as good as quilting suture in preventing seroma formation at pectoral area after mastectomy

Background

The aim of this study was to compare conventional suture with prolonged timing of drainage with quilting suture on the formation of seroma at pectoral area after mastectomy (ME) with sentinel lymph node biopsy (SLN) or axillary lymph node dissection (ALND) for breast cancer.

Methods

Three hundred and eighty-eight consecutive breast cancer patients were retrospectively analyzed and categorized into three groups. Patients in group 1 were with quilting suture, group 2 with conventional suture and 13–15 days drainage in situ, and group 3 with conventional suture and 20–22 days drainage. The primary outcome was the incidence of grades 2 and 3 seroma at anterior pectoral area within 1 month postoperatively. Cox regression was used for analysis.

Results

The incidence of grades 2 and 3 seroma was comparable among groups (9.5% vs. 7.9% vs. 5.3%, p = 0.437), as well as late grades 2 and 3 seroma among groups (4.3% vs. 2.9% vs. 1.5%, p = 0.412). Old age, high body mass index, and hypertension were independent risk factors for grades 2 and 3 seroma.

Conclusions

Prolonged timing of drainage to 13–15 days in conventional suture was long enough to decrease the incidence of grades 2 and 3 seroma as lower as that in quilting suture group at pectoral area within 1 month after mastectomy.

Fibrin Sealants and Axillary Lymphatic Morbidity: A Systematic Review and Meta-Analysis of 23 Clinical Randomized Trials

Simple Summary

Axillary dissection is a highly mobile procedure with severe lymphatic consequences. The off-label application of fibrin sealants in the axilla, with the sole aim to eliminate dead space and to provoke sealing of the disrupted lymphatic vessels at the end of axillary dissection, is an experimental procedure to reduce lymphatic morbidity. The aim of our systematic review and meta-analysis is to investigate the effects of fibrin sealants on lymphatic morbidity after axillary dissection. Our results show that this experimental procedure is able to decrease the total axillary drainage output, the number of days before the axillary drainage is removed, and the length of hospital stay. However, no effects on the occurrence rate of axillary lymphocele or on the surgical site complications rate were demonstrated

Abstract

Background: use of fibrin sealants following pelvic, paraaortic, and inguinal lymphadenectomy may reduce lymphatic morbidity. The aim of this meta-analysis is to evaluate if this finding applies to the axillary lymphadenectomy. Methods: randomized trials evaluating the efficacy of fibrin sealants in reducing axillary lymphatic complications were included. Lymphocele, drainage output, surgical-site complications, and hospital stay were considered as outcomes. Results: twenty-three randomized studies, including patients undergoing axillary lymphadenectomy for breast cancer, melanoma, and Hodgkin’s disease, were included. Fibrin sealants did not affect axillary lymphocele incidence nor the surgical site complications. Drainage output, days with drainage, and hospital stay were reduced when fibrin sealants were applied (p < 0.0001, p < 0.005, p = 0.008). Conclusion: fibrin sealants after axillary dissection reduce the total axillary drainage output, the duration of drainage, and the hospital stay. No effects on the incidence of postoperative lymphocele and surgical site complications rate are found.

Effectiveness of Cyanoacrylate in Reducing Seroma Formation in Breast Cancer Patients Post-Axillary Dissection: A Randomized Controlled Trial

Background/Purpose

Seroma is a common complication after axillary dissection in women with node-positive breast cancer. We aim to determine the effect of Cyanoacrylate on reducing seroma formation in patients undergoing axillary dissection. This a randomized clinical trial.

Methods

This is a single-center, randomized, single-blinded, and two-arm parallel study. Women with node-positive breast cancer eligible for axillary dissection were enrolled. Patients with a Body Mass Index (BMI) greater than 35 kg/m², those who underwent immediate breast reconstruction, and/or received neoadjuvant chemotherapy were excluded. Patients were randomized in a 1:1 ratio, and were stratified according to their age, BMI, tumor size, and operation type. The primary endpoint was the total seroma volume (the total drained volume and the total aspirated volume after drain removal). Data presented as mean and range when applicable.

Results

111 patients were randomized (Cyanoacrylate 57; control 54). 105 patients were analyzed. Sixty-nine patients underwent breast conserving surgery, and 36 underwent modified radical mastectomy. There was no difference in the total seroma volume between the Cyanoacrylate vs. control arms (1,304 (60–4,950) vs. 1,446 (100–5,223) ml, p=0.458). Wound infection, flap necrosis, number of manual aspirates, and hematoma formation were not statistically different between the two groups. Time to drain removal was shorter in the Cyanoacrylate arm (11.04(3–23) vs. 13.84(3–37) days, p=0.015). The use of Cyanoacrylate was not cost effective ($586.93 (550–748) vs. $29.63 (0–198), p<0.001). Higher seroma volume was correlated with modified radical mastectomy, older age, and BMI more than 30 kg/m².

Conclusion

Cyanoacrylate did not reduce seroma formation and its use was not cost effective.

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.

Quilting suture is better than conventional suture with drain in preventing seroma formation at pectoral area after mastectomy

BACKGROUND

The aim of this study was to compare quilting suture with conventional suture on the formation of seroma at pectoral area after mastectomy (ME) with sentinel lymph nodes biopsy (SLN) or axillary lymph nodes dissection (ALND) for breast cancer.

METHODS

Two hundred thirty-five consecutive breast cancer patients were retrospectively analyzed. The primary outcome was the incidence of Grade 2 or Grade 3 seroma at anterior pectoral area within 1 month postoperatively. We categorized seroma into early or late seroma according to the drainage removal time. Cox regression was used for analysis.

RESULTS

The incidence of Grade 2 and 3 seroma was significantly higher in the conventional suture group compared with that in the quilting suture group (19.3% vs. 9.5%, p = 0.032), which was attributed to the late seroma in Grade 2 and 3. Quilting suture was associated with longer time for fixing flaps compared with that of conventional suture (504.7 s vs. 109.1 s, p < 0.001), but with less volume of drainage. Old age, high body mass index and conventional suture were independently risk factors for Grade 2 and 3 seroma.

CONCLUSIONS

Quilting suture decreased the incidence of Grade 2 and 3 seroma at pectoral area within 1 month after mastectomy, especially the late seroma in Grade 2 and 3.

The recent progress of tissue adhesives in design strategies, adhesive mechanism and applications

Tissue adhesives have emerged as an effective method for wound closure and hemostasis in recent decades, due to their ability to bond tissues together, preventing separation from one tissue to another. However, existing tissue adhesives still have several limitations. Tremendous efforts have been invested into developing new tissue adhesives by improving upon existing adhesives through different strategies. Therefore, highlighting and analyzing these design strategies are essential for developing the next generation of advanced adhesives. To this end, we reviewed the available strategies for modifying traditional adhesives (including cyanoacrylate glues, fibrin sealants and BioGlue), as well as design of emerging adhesives (including gelatin sealants, methacrylated sealants and bioinspired adhesives), focusing on their structures, adhesive mechanisms, advantages, limitations, and current applications. The bioinspired adhesives have numerous advantages over traditional adhesives, which will be a wise direction for achieving tissue adhesives with superior properties.

Increasing the incidence of drain-free day-case mastectomies with the use of a fibrin tissue sealant; data from a single surgical center in the United Kingdom

Day-case mastectomy surgery provides benefits to both patients and hospitals. Key barriers are the use of a drain and the risk of postoperative seroma formation. We introduced the use of a tissue sealant (Artiss) into the surgical site (post-mastectomy without immediate reconstruction and postaxillary clearance) and evaluated its effect on our practice, particularly day-case rates. A prospective audit of 177 patients who underwent a simple mastectomy with or without axillary surgery, or axillary node clearance with or without breast-conserving surgery was conducted at a single surgical center in the UK between November 2015 and November 2016. Artiss was used in all operations and, where appropriate, the drain was omitted to facilitate day-case surgery. The clinical outcomes were compared between patients undergoing different operations and duration of hospital stay. There was no statistically significant difference between day-case patients and inpatients in seroma aspiration rates (24.5% and 21.7%, respectively; P = 0.381) or other complications (22.4% and 16.1%, respectively; P = 0.106). The day-case mastectomy rate increased from 3.9% in the first quarter to 45.5% in the final quarter, which was a significant increase reaching well beyond the national target. The use of Artiss enabled us to increase the drain-free day-case surgery rates over a 1-year period, exceeding the 30% target recommended by the British Association of Day Surgery. We did not observe any increase in patient morbidity, and the change was cost-effective. We have now implemented the routine use of Artiss in women undergoing simple mastectomy with or without axillary surgery and stand-alone axillary node clearances as part of enhanced recovery clinical pathways.

Use of a Lysine-Derived Urethane Surgical Adhesive as an Alternative to Progressive Tension Sutures in Abdominoplasty Patients: A Cohort Study

BACKGROUND

Fluid accumulation is a common complication after abdominoplasty procedures, and is typically managed by the placement of post-surgical drains. Progressive tension sutures (PTS) have been shown to be an effective approach to reduce the dead space by point-wise mechanical fixation, allowing for drain-free procedures. Lysine-derived urethane surgical adhesive provides an alternative approach for mechanical fixation and reduction of dead space, and may reduce surgery time compared to PTS.

OBJECTIVES

This prospective, controlled, single center clinical study compared progressive tension suture wound closure technique without drains (control) to tissue adhesive wound closure technique without drains (test) during abdominoplasty surgery. The objective was to determine if lysine-derived urethane surgical adhesive is an effective alternative to PTS for drain-free abdominoplasty procedures.

METHODS

Patients undergoing abdominoplasty who met the established inclusion/exclusion criteria were consented and enrolled in the study. Ten PTS (control) cases were performed, followed immediately by 10 tissue adhesive (test) cases.

RESULTS

Surgeries were completed over an 8-month period. No statistical differences were identified between the two groups with regard to age, BMI, dissection surface area or flap weight. No clinical seroma formation was observed in either group. In the control (PTS) group, two patients developed small areas of dermal closure suture abscess requiring removal of suture material. One control patient developed drainage and fat necrosis thought to be related to PTS above the incision and later required a scar revision. One tissue adhesive patient developed hypertrophic scars of both her breast reduction and abdominoplasty scars requiring additional treatment.

CONCLUSIONS

Lysine-derived urethane surgical adhesive was applied in less time than PTS, even after accounting for holding pressure for 5 minutes. The tissue adhesive provided four times the number of attachment points compared to PTS, although the significance of this is not clear. Based on these results, the use of lysine-derived urethane surgical adhesive was found to be a safe and effective alternative to PTS to reduce seroma formation in drain-free abdominoplasty procedures.
