Prospective randomized controlled study to assess the value of a hemostatic and sealing agent for preventing seroma after axillary lymphadenectomy

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.

Efficacy of four different hemostatic agents in thyroid surgery in reducing the amount of post-operative fluid collection

PURPOSES

Postoperative bleeding remains a life-threatening complication in thyroid surgery. The aim was to assess the efficacy of four different hemostatic agents, Collagen-Fibrinogen-Thrombin Patch (CFTP) in two sizes (3 × 2.5 cm and 9.5 × 4.8 cm), polysaccharide particles (1 g) and Cellulose Gauze (2.5 × 5 cm) on postoperative drainage volume (DV) compared to a control group.

METHODS

We included from October 2007 until Mai 2011, 150 patients (30 per group) for this monocentric, retrospective case-controlled study. Patients were scheduled for a hemithyroidectomy or thyroidectomy. The primary endpoint was the postoperative DV within the first 24 h, secondary the incidence of adverse events.

RESULTS

There were no difference in demographic parameters. The mean DV (± SD) was 51.15 (± 36.86) ml in the control, 50.65 (± 42.79) ml in small (3 × 2.5 cm), 25.38 (± 23.99) ml in large CFTP (9.5 × 4.8 cm), 53.11 (± 39.48) ml in the polysaccharide particles and 48.94 (± 30.59) ml in the cellulose gauze group. DV was significantly reduced with the large CFTP (p < 0.05) compared to all other groups. There were no adverse events.

CONCLUSIONS

We were able to demonstrate a significant reduction in the DV for the large CFTP group compared to the other collectives. Although this as being associated with not inconsiderable costs and we would only recommend its use for high-risk patients only.

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.

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.

Reduction of postoperative lymphorrhoea in patients undergoing radical lymphadenectomy for stage III melanoma: prospective study using collagen-fibrin patches

BACKGROUND

Radical lymph nodes dissection (RLND) is the standard procedure for regional control of disease in patients with metastatic melanoma (stage III). Because of its aggressiveness, lymphorrhoea is a constant problem in postoperative.

METHODS

In this prospective nonrandomized study with a retrospective analysis of data, patients undergoing surgical treatment of axillary or iliac-inguinal RLND received standard treatment plus a collagen-fibrin sealant patch (TachoSil) (N.=50) or standard treatment alone (N.=50). The first endpoint was the comparison between the treated population and the control group, in terms of persistence of drainage and average daily volume of lymphorrhoea. The second aim was to relate patients' BMI, volume of lymphorrhoea and time of drainage in the two groups.

RESULTS

In the comparison between the two groups receiving or not the treatment with collagen-fibrin patch, we found an average difference both in the volume of daily lymphorrhoea (42.91±6.61 cc) and in the persistence of drainage (9.292±1.644 days) with P value <0.0001. Besides, the collagen-fibrin patch was actually effective in reducing lymphorrhoea and time of drainage, regardless of patients' BMI.

CONCLUSIONS

The results of this study confirm and support the starting thesis: TachoSil is an effective tissue sealant able to reduce lymphorrhoea and drainage removal times following a radical lymphadenectomy, independently from the BMI.

Intraoperative hypertonic saline irrigation preventing seroma formation and reducing drain secretion in extended endoscopic hernia and linea alba reconstruction glue

PURPOSE

Subcutaneous Seroma formation (SF) is commonly seen after abdominal wall Hernia surgeries and reconstructive surgeries due to large dissecting dead space and is associated with increased morbidity. SF is common particularly after big abdominal wall hernia repairs and its treatment can be challenging and long. Current prevention methods are not consistent and the treatment includes repeated aspirations and drains, both are associated with higher risk for infections. The purpose of this article is to present a novel and simple technique of Intraoperative Hypertonic Saline Irrigation (IHSI) to abdominal wall subcutaneous large dead space, which prevent postoperative SF and enables early drain removal due to reduced secretions.

METHODS

Eight patients undergone the Extended Endoscopic Hernia & Linea Alba Reconstruction Glue surgery (eEHLARglue), for Ventral Hernias (VH) and Rectus Muscles Separation (RMS). An extensive Endoscopic 450cm² dissection free surface of the anterior Rectus fascia, is performed prior to Hernia dissection and closing of the RMS. It is followed by onlay mesh placing over the repaired Rectus muscles and the mesh is fused into the muscles by Fibrin Glue. The novel preventive method is based on Intraoperative Irrigation of the vast cavity through the two 10 mm JP closed system drains with 20 cc of NaCl 12% left at site for 10 min.

RESULTS

Our early results with all our patients show seroma prevention, lower secretion rate of 20 cc in 10 h and drain removal within 20-24 h.

CONCLUSIONS

IHSI enhance adhesion formation and reduce secretion rate in wide subcutaneous dissection space like in eEHLARglue, therefore enables early drain removal and prevent SF. As a result, reducing overall morbidity and hospitalization period, decreasing inconveniency and cost saving of multiple outpatient visits or additional surgery. This simple technique could be used in other potential postoperative SF surgeries. Further larger study with a longer follow up is advised.

Impact of a Surgical Sealing Patch on Lymphatic Drainage After Axillary Dissection for Breast Cancer: The SAKK 23/13 Multicenter Randomized Phase III Trial

BACKGROUND

Several studies and a meta-analysis showed that fibrin sealant patches reduced lymphatic drainage after various lymphadenectomy procedures. Our goal was to investigate the impact of these patches on drainage after axillary dissection for breast cancer.

METHODS

In a phase III superiority trial, we randomized patients undergoing breast-conserving surgery at 14 Swiss sites to receive versus not receive three large TachoSil^® patches in the dissected axilla. Axillary drains were inserted in all patients. Patients and investigators assessing outcomes were blinded to group assignment. The primary endpoint was total volume of drainage.

RESULTS

Between March 2015 and December 2016, 142 patients were randomized (72 with TachoSil^® and 70 without). Mean total volume of drainage in the control group was 703 ml [95% confidence interval (CI) 512-895 ml]. Application of TachoSil^® did not significantly reduce the total volume of axillary drainage [mean difference (MD) -110 ml, 95% CI -316 to 94, p = 0.30]. A total of eight secondary endpoints related to drainage, morbidity, and quality of life were not improved by use of TachoSil^®. The mean total cost per patient did not differ significantly between the groups [34,253 Swiss Francs (95% CI 32,625-35,880) with TachoSil^® and 33,365 Swiss Francs (95% CI 31,771-34,961) without, p = 0.584]. In the TachoSil^® group, length of stay was longer (MD 1 day, 95% CI 0.3-1.7, p = 0.009), and improvement of pain was faster, although the latter difference was not significant [2 days (95% CI 1-4) vs. 5.5 days (95% CI 2-11); p = 0.2].

CONCLUSIONS

TachoSil^® reduced drainage after axillary dissection for breast cancer neither significantly nor relevantly.
