The Combination of Fibrin Glue and Quilting Reduces Drainage in the Extended Latissimus Dorsi Flap Donor Site:

Evaluation of bone marrow-derived mesenchymal stem cells with eggshell membrane for full-thickness wound healing in a rabbit model

Biomaterials capable of managing wounds should have essential features like providing a natural microenvironment for wound healing and as support material for stimulating tissue growth. Eggshell membrane (ESM) is a highly produced global waste due to increased egg consumption. The unique and fascinating properties of ESM allow their potential application in tissue regeneration. The wound healing capacity of bone marrow-derived mesenchymal stem cells (BM-MSCs), ESM, and their combination in rabbits with full-thickness skin defect (2 × 2 cm2) was evaluated. Twenty-five clinically healthy New Zealand White rabbits were divided into five groups of five animals each, with group A receiving no treatment (control group), group B receiving only fibrin glue (FG), group C receiving FG and ESM as a dressing, group D receiving FG and BM-MSCs, and group E receiving a combination of FG, ESM, and BM-MSCs. Wound healing was assessed using clinical, macroscopical, photographic, histological, histochemical, hematological, and biochemical analysis. Macroscopic examination of wounds revealed that healing was exceptional in group E, followed by groups D and C, compared to the control group. Histopathological findings revealed improved quality and a faster rate of healing in group E compared to groups A and B. In addition, healing in group B treated with topical FG alone was nearly identical to that in control group A. However, groups C and D showed improved and faster recovery than control groups A and B. The macroscopic, photographic, histological, and histochemical evaluations revealed that the combined use of BM-MSCs, ESM, and FG had superior and faster healing than the other groups.

Fibrin Sealants Do Not Reduce the Rate of Seroma Formation in Postmastectomy Breast Reconstruction: A Systematic Review and Meta-analysis

Background Breast reconstruction using deep inferior epigastric perforator (DIEP) and latissimus dorsi (LD) flaps following mastectomy are associated with seroma formation, most commonly at the donor site. We sought to perform an updated systematic review and meta-analysis on the effects of fibrin sealant on donor-site complications following DIEP and LD flap breast reconstruction.

Methods A comprehensive literature search was conducted (March 2021) in PubMed, OVID, and Cochrane databases. Articles analyzing the efficacy of fibrin glue in reducing donor-site morbidity in DIEP and LD breast reconstruction were included. The outcomes assessed were seroma formation and duration of drainage.

Results A total of 17,265 articles were screened, and 9 articles were selected for analysis, which comprised 632 surgical sites in 611 patients. Comparing fibrin glue and quilting to quilting alone showed no significant difference in seroma formation (pooled risk ratio [RR]: 0.51; 95% confidence interval [CI]: 0.12, 2.25). Similarly, comparing fibrin glue alone to no fibrin glue showed no significant difference in seroma formation (pooled RR: 1.03; 95% CI: 0.66, 1.61) or duration of drain (pooled RR: −0.85; 95% CI: −4.09, 2.40); there was however a difference in duration of drain in those who received fibrin glue and quilting versus quilting alone (pooled RR: −2.13; 95% CI: −3.27, −0.99).

Conclusion The existing literature supports that the use of fibrin glue is not associated with a decrease in seroma formation in DIEP and LD flaps and is weakly associated with a reduction in the drainage duration only if used in conjunction with quilting.

Successful Elbow Flexion Reconstruction Using Latissimus Dorsi Muscle Transfer Following a Road Traffic Accident and Upper Limb Trauma

BACKGROUND Several surgical procedures to restore elbow flexion have been reported in the literature. Multiple factors direct the selection of appropriate procedures for each patient, including hand dominance, neurovascular injury, and comorbidities. Traumatic damage to the anterior compartment of the arm is an indication for latissimus dorsi transfer, which can restore elbow flexion. Bipolar pedicled latissimus dorsi (LD) flap is a design used very rarely to simultaneously reconstruct biceps brachii soft-tissue defects and regain complete flexion function. We report the case of a 30-year-old man who underwent successful elbow flexion reconstruction using latissimus dorsi muscle transfer following a road traffic accident and upper limb trauma. CASE REPORT A 30-year-old man presented with acute compartment syndrome caused by a road traffic accident and impact trauma to the left arm. The surgical evaluation revealed proximal biceps tendons rapture; therefore, immediate repair and therapeutic fasciotomy were done. Subsequently, unsuccessful repair resulted in total necrosis of the biceps muscle, which necessitated debridement of the biceps muscle. Delayed reconstruction with an LD flap was successfully done after stabilization of the patient's condition. The flap was harvested as free-pedicled, then modified into a tube-like shape to resemble the biceps muscle. CONCLUSIONS This report has shown that the surgical procedure of latissimus dorsi muscle transfer can successfully restore elbow function following upper limb trauma; however, preoperative planning and postoperative follow-up are crucial for functional reconstruction of the upper extremity. In addition, carefully selecting reconstructive surgery considering patient factors, degree of injury, and the institution's capacity are essential factors in achieving optimal function restoration with minimal complications.

Efficacy of Fibrin Sealants in Preventing Seroma Formation in Reduction Mammaplasty: A Single Surgeon's Experience

BACKGROUND

Fibrin sealant is a controversial method for reducing seroma formation. It is comprised of human proclotting factors, fibrinogen and thrombin. Fibrin sealants have been extensively studied for their efficacy in reducing the rates of seroma by sealing the dead space; however, in most studies, the sealants are used with surgical drains. According to the U.S. Food and Drug Administration, fibrin sealant carries the risk of life-threatening thromboembolic complications, gas emboli, and transmission of infectious agents. Despite these concerns, many plastic surgeons use such products in ambulatory surgeries even though its effect on seroma formation has yet to be elucidated. The aim of our study is to determine the efficacy of fibrin sealants in seroma prevention in reduction mammoplasty with and without surgical drains.

METHODS

A retrospective chart review was performed of all bilateral reduction mammaplasty by a single-surgeon from 2014 to 2018. Patients had at least 90 days postoperative follow-up. Exclusion criteria consisted of patients younger than 18 years, had prior breast surgery, or had an incidental cancer diagnosis in breast reduction tissue specimen.

RESULTS

On analysis, 159 patients met inclusion criteria and were categorized into group 1, with fibrin sealant (n = 101) and group 2, no fibrin sealant (n = 58). There were no statistical differences in patient demographics. There was no significant difference in the incidence of seroma between group 1 and group 2 (21% vs 19%, P = 0.782). Group 1 incidence of seroma was further analyzed by sealant type: Tisseal, Floseal, and Evicel (12% vs 27% vs 23%, P = 0.436). In group 1, the use of sealant alone was more likely to result in seroma formation when compared with the combination of sealant and surgical drains (25% vs 8%, P = 0.069).

CONCLUSIONS

There is no difference in rate of seroma formation with the use of fibrin sealants in reduction mammaplasty. The use of fibrin sealants without surgical drains may increase the rate of seromas. Plastic surgeons could consider weighing the risk versus benefits in using fibrin sealants with or without drains in ambulatory surgeries.

Utility of autologous fibrin glue in the donor site of free abdominal flap for breast reconstruction: A randomized controlled study

BACKGROUND

Seroma formation at the donor site is a common complication of breast reconstruction using free abdominal flap. In this study, we assessed the benefits of use of autologous fibrin glue (AFG) at the donor site.

METHODS

This randomized controlled study compared AFG group (n = 61) with commercial fibrin glue (CFG) group (n = 79). Owing to the high volume of AFG (10 mL), AFG group received fibrin glue at both the anastomosis and the donor sites, whereas CFG group received fibrin glue only at the anastomosis site. Operative protocols and the criteria for postoperative drain removal were identical in both groups. Patient characteristics and abdominal discharge were compared between the two groups.

RESULTS

Since anemia was a contraindication for use of AFG, preoperative Hb in CFG group was significantly lower than that in AFG group; other factors were comparable in the two groups. The mean total abdominal drain volumes on first postoperative day (POD1) and POD2 was (AFG vs. CFG) 130.9 vs. 169.4 mL (P < 0.001) and 131.0 vs. 162.8 mL (P = 0.03), respectively. On POD3, there was no significant difference in this respect (116.2 vs. 128.4 mL, P = 0.19). The mean time for removal of all abdominal drains was significantly lower in AFG group (7.4 vs. 8.4 days; P = 0.01).

CONCLUSIONS

AFG reduced the discharge at the donor site of free abdominal flap, especially in the early postoperative period. AFG helped to reduce the abdominal drainage period.

The Use of Fibrin-based Tissue Adhesives for Breast in Reconstructive and Plastic Surgery

BACKGROUND

Breast plastic surgery is a rapidly evolving field of medicine. The modern view of surgical trends reflects the desire to minimize complications and introduce advanced technologies. These always will be priorities for surgeons. Reconstructive surgery, a branch of plastic surgery focusing on restoration of lost functional and aesthetic component, seeks to enhance psychological rehabilitation and improves the quality of life, as well as aesthetic recovery.

OBJECTIVE

This review addresses the action of fibrin agents and their effect on the quality of surgical hemostasis.

DISCUSSION AND CONCLUSION

The fundamental goals for the surgeon are to perform a minimally traumatic intervention and to prevent any form of complication. Achieving complete hemostasis is an intraoperative necessity. Timely prevention of bleeding and hemorrhagic phenomena can affect not only the outcome of the operation, but also the incidence of postoperative complications. Topics include the integrity of microvascular anastomoses, tissue adhesion, and the incidence of seromas and hematomas associated with fibrin glue usage. The literature on fibrin adhesives with respect to prevention of postoperative complications, and the effectiveness with active drainage also are analyzed.

The Role of Negative-Pressure Wound Therapy in Latissimus Dorsi Flap Donor Site Seroma Prevention: A Cohort Study

Background

Donor site seroma is the most common complication after latissimus dorsi (LD) flap harvest. This study aimed to evaluate the efficacy of negative-pressure wound therapy (NPWT) in preventing donor site seroma formation after the harvest of an LD flap for breast reconstruction.

Methods

In this prospective matched-pair study, 40 patients in whom an LD flap was harvested for breast reconstruction were enrolled. NPWT was used in 20 patients, and in a control group composed of another 20 patients, the conventional donor site dressing technique was used. Information was collected regarding postoperative complications, the incidence of seroma, total drainage volume, the number of percutaneous seroma aspirations, and the volume aspirated.

Results

In the NPWT group, the incidence of seroma formation after drain removal was significantly lower than in the control group (15% vs. 70%; odds ratio=0.07; relative risk, 0.24). Both the mean percutaneous aspirated volume (P=0.004) and the number of percutaneous aspirations (P=0.001) were also significantly lower in the NPWT group. There were no significant differences in the total drainage volume or the duration of wound drainage between the NPWT dressing group and the control group (P>0.05).

Conclusions

This study showed that NPWT is a promising tool for reducing the incidence of seroma formation after removing the drain at the donor site after LD flap harvesting. It is a simple and safe technique.

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.

Single-stage Reconstruction of Elbow Flexion Associated with Massive Soft-Tissue Defect Using the Latissimus Dorsi Muscle Bipolar Rotational Transfer

In the upper extremity, the latissimus dorsi muscle can be used as an ipsilateral rotational muscle flap for soft-tissue coverage or functional reconstruction of arm and elbow. Patients who have both major soft-tissue loss and functional deficits can be successfully treated with a single-stage functional latissimus dorsi rotational muscle transfer that provides simultaneous soft-tissue coverage and functional reconstruction.

METHODS

Our data base was queried for all patients undergoing a rotational latissimus dorsi muscle transfer for simultaneous soft-tissue coverage and functional reconstruction of elbow flexion. Four patients were identified. A chart review documented the mechanism of injury, associated injuries, soft-tissue defect size, number of surgical procedures, length of follow-up, last elbow range of motion, and flexion strength.

RESULTS

Four patients with loss of elbow flexion due to traumatic loss of the anterior compartment muscles and the overlying soft tissue underwent simultaneous soft-tissue coverage and elbow flexorplasty using the ipsilateral latissimus dorsi as a bipolar muscle rotational tissue transfer. All flaps survived and had a recovery of Medical Research Council Grade 4/5 elbow flexion strength. No additional procedures were required for elbow flexion. The surgical technique is described and supplemented with surgical technique video and patient outcome.

CONCLUSIONS

This patient series augments the data provided in other series supporting the safety and efficacy of this procedure which provides both soft-tissue coverage and functional restoration of elbow flexion as a single-stage procedure in the setting of massive traumatic soft-tissue loss of the arm.

Seroma in Prosthetic Breast Reconstruction

BACKGROUND

Seroma, as a complication of prosthetic breast reconstruction, results in patient distress, increased office visits, undesirable aesthetic outcomes, and--importantly--may escalate to infection and frank prosthesis loss. Herein, the authors review the pathophysiology and risk factors and attempt to collate published practices for avoidance and management of seroma.

METHODS

A systematic literature review was performed using MEDLINE, Web of Science, Embase, and Cochrane Library for studies published between 2000 and January of 2015. Random-effects meta-analysis was used to estimate the overall pooled incidence of seroma and to examine the effect of drain number and acellular dermal matrix use.

RESULTS

Seventy-two relevant primary articles and three systematic reviews were identified. Fifty-one citations met inclusion criteria, including two randomized controlled trials. The overall pooled incidence was 5.4 percent (95 percent CI, 4.1 to 6.7 percent). Obesity, acellular dermal matrix, and preoperative irradiation were cited risk factors. Pooled relative risk for acellular dermal matrix was 1.83 (95 percent CI, 1.28 to 2.62). Drain practices were collated from 34 articles.

CONCLUSIONS

Seromas following prosthetic breast reconstruction are complicated by the hypovascular, proinflammatory milieu of the mastectomy skin flap, the geometrically complex dead space, and the presence of a foreign body with potential contamination and biofilm. There is reasonable evidence to suggest that these factors contribute to a progression of seroma to infection and prosthesis loss. These findings have motivated this summary article on current practice guidelines and strategies to prevent and treat seromas.

Prospective control study using fibrin sealants and Harmonic® scalpel in Latissimus Dorsi flap transfer

BACKGROUND

Latissimus dorsi flap (LD) is used in breast reconstruction procedures, although prolonged donor site drainage is a frequent complication. To decrease this problem, quilting sutures and/or fibrin sealants were proposed, with alternate results. The primary objective of this study was to assess the effectiveness of Tisseel® in association with the Harmonic Synergy® blade system to reduce this complication.

MATERIALS AND METHODS

Between 2010-2012, 20 consecutive patients undergoing immediate unilateral breast reconstruction with LD were enrolled in the study (Group A) and matched with 20 patients in which LD was raised with electrocautery (Group B), and 20 patients in which LD was harvested with Harmonic® (Group C). After informed consent acquisition, Harmonic® was used in Group A for LD harvesting, but differed from other groups as fibrin glue was applied to the donor site prior to closure. In all groups donor site drainage measurements at 24 and 48 hours, total drain volume, days to drain removal, operation time, and complication rate were recorded. Pearson's Chi-squared, ANOVA, and Bonferroni post-hoc tests were used to analyze the data.

RESULTS

Data analysis did not show any statistical difference. Prolonged drains output ≥ 15 days occurred in one patient of Group A and C, and in three Group B patients.

CONCLUSION

Although the combined use of Harmonic® and Tisseel® presents a low donor site fluid collection rate, the fibrin glue seems not to have further beneficial effects in reducing the post-operative serous drainage or to lead to an early drain removal when compared to Harmonic® only.

The impact of tissue glue in wound healing of head and neck patients undergoing neck dissection

We investigated the impact of fibrin glue on postoperative drainage amount and duration in head and neck cancer patients who underwent neck dissection. This study was a prospective randomized controlled trial. Patients who were scheduled to undergo neck dissection due to head and neck cancer were eligible for this study. After receiving a detailed explanation, all patients signed an informed consent form before enrollment. Patients were then randomly assigned to the study group (fibrin glue) or control group. In the study group, 2 ml of fibrin glue (Tissucol(®); Duploject, Baxter AG) was applied on the surface of the surgical wound before closure. Basic demographic data along with tumor-related features, operation-related variables, postoperative drainage amount/duration, postoperative pain, and analgesic usage were collected and analyzed. A total of 15 patients were included in the final analyses, with eight patients in the study group and seven patients in the control group. No significant differences were found between the two groups in age, gender, primary site, clinical N stage, neck dissection levels, perioperative bleeding, postoperative drainage amount/duration, hospitalization duration, and postoperative pain status. The application of 2 ml fibrin glue by the method described herein did not reduce the postoperative drainage amount/duration nor the postoperative pain status in patients who underwent neck dissection.

Fibrin Sealants and Quilting Suture for Prevention of Seroma Formation Following Latissimus Dorsi Muscle Harvest: A Systematic Review and Meta-analysis

PURPOSE

Despite popular use of fibrin sealants and quilting sutures for prevention of seroma formation at the donor site of the latissimus dorsi (LD) muscle flap, there is still no consensus regarding their efficacy. The present review estimates the potential benefits of fibrin and quilting suture for reducing seroma-related morbidity following LD muscle harvest.

METHODS

Using Medline, Ovid, and Cochrane databases, two-arm studies evaluating the efficacy of fibrin sealants, quilting suture, or their combination for prevention of seroma formation following LD muscle transfer were searched. The outcome measure was the incidence of seroma, total drainage volume from the back, periods of drainage in situ, volume of seroma, and frequency of aspiration for treatment of seroma. The efficacy on reducing the seroma-related morbidity for each procedure was estimated by meta-analytic methodology.

RESULTS

Fourteen studies were analyzed. Fibrin alone failed to reduce seroma-related morbidities compared with no intervention, while fibrin instillation combined with quilting suture halved the risk of seroma formation (relative risk (RR): 0.51, 95 % CI 0.12-2.16) and significantly reduced total drainage volume (mean difference (MD); -320.80, 95 % CI -389.92 to -251.68) and drain indwelling periods (MD -1.62, 95 % CI -2.91 to -0.33) compared with quilting suture alone. Quilting suture had significant protective effects on reducing the risk of seroma formation (RR 0.38, 95 % CI 0.19-0.75), total drainage volume (MD -284.10, 95 % CI -474.61 to -93.60), and drain indwelling periods (MD -3.65, 95 % CI -5.43 to -1.87), and its efficacy was enhanced by combining with fibrin.

CONCLUSIONS

According to this review, both fibrin and quilting sutures contributed in varying degrees to reducing seroma-related morbidity following LD muscle transfer, and their combination can have a synergistic effect. Although large-scaled, randomized studies are needed, the combination of both procedures may be considered an effective option for minimizing the risk of seroma.

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.

Continuous high-pressure negative suction drain: new powerful tool for closed wound management: clinical experience

BACKGROUND

Although various reconstructive flap surgeries have been successfully performed, there still are difficult wound complications, such as seroma formation, wound margin necrosis, delayed wound healing, and even flap failures. The negative-pressure wound therapy has been described in detail in the literature to assist open chronic/complex wound closure in reconstructive surgery. However, the negative-pressure wound therapy was difficult to be applied under the incisional closed wounds.

METHODS

A total of 23 patients underwent the various reconstructive flap surgeries with continuous high-pressure negative suction drain. Instead of using regular suction units, Barovac (50-90 mm Hg, Sewoon Medical, Seoul, Republic of Korea) drainage tubes were connected to the wall suction unit, providing continuous high-powered negative pressure. In addition, continuous subatmospheric suction pressure (100-300 mm Hg) was applied. Outcome of the measures was obtained from the incidence of seroma, volume of postoperative drainage, hospitalization period, and incidence of other typical wound complications. Dead space was evaluated postoperatively with ultrasonography.

RESULTS

Using continuous high-pressure negative suction drain, successful management of seroma was obtained without any major complication such as wound infection, flap loss, and wound margin necrosis, except for only 1 case of seroma after discharge from the hospital. The indwelling time of the drain in the latissimus dorsi donor site was significantly reduced in comparison with the authors' previous data (P = 0.047). The volume of drainage and hospitalization period were also reduced; however, these were not statistically significant. The dead space with continuous high-pressure negative suction drain was more reduced than in the control group in the immediate postoperative period and confirmed with ultrasonography.

CONCLUSIONS

Continuous high-pressure negative suction drain might be the simple and powerful solution in the management of challenging closed wounds.

Fibrin sealant and lipoabdominoplasty in obese grade 1 and 2 patients

BACKGROUND

Ever since lipoabdominoplasty was first developed to achieve better aesthetic outcomes and less morbidity, the rate of seroma formation, especially in obese patients, has disturbed plastic surgeons. The aim of this study was to evaluate the effect of fibrin sealant in the prevention of seroma formation after lipoabdominoplasty in obese patients.

METHODS

Sixty patients with a body mass index (BMI) between 30 and 39.9 were assigned randomly to 1 of 2 groups (30 patients each). Group A underwent lipoabdominoplasty with fibrin glue, while group B underwent traditional lipoabdominoplasty; both had closed suction drainage applied to the abdomen. The patients' demographics and postoperative complications were recorded. Seroma was detected using abdominal ultrasound examinations at two postoperative periods: between postoperative days 10 and 12 and, between postoperative days 18 and 21.

RESULTS

The age range was 31 to 55 years (38.5±9.5 years) in group A and 25 to 58 years (37.8±9.1 years) in group B, while the mean BMI was 31.4 to 39.9 kg/m(2) (32.6 kg/m(2)) in group A and 32.7 to 37.4 kg/m(2) (31.5 kg/m(2)) in group B. In group A, the patients had a complication rate of 10% in group A versus 43% in group B (P<0.05). The incidence of seroma formation was 3% in the fibrin glue group but 37% in the lipoabdominoplasty-alone group (P<0.05).

CONCLUSIONS

Lipoabdominoplasty with the use of autologous fibrin sealant is a very effective method that significantly reduces the rate of postoperative seroma.

Randomized clinical trial on the effect of fibrin sealant on latissimus dorsi donor-site seroma formation after breast reconstruction

BACKGROUND

Latissimus dorsi (LD) flap procedures comprise 50 per cent of breast reconstructions in the UK. They are frequently complicated by seroma formation. Fibrin sealants may reduce seroma volumes at the donor site. The aim was to investigate the effect of fibrin sealant (Tisseel(®)) on total seroma volumes from the breast, axilla and back (donor site) after LD breast reconstruction. Secondary outcomes were specific back seroma volumes together with incidence and severity of wound complications.

METHODS

Consecutive women undergoing implant-assisted or extended autologous LD flap reconstruction were randomized to either standard care or application of fibrin sealant to the donor-site chest wall. All participants were blinded for the study duration but assessors were only partially blinded. Non-parametric methods were used for analysis.

RESULTS

A total of 107 women were included (sealant 54, control 53). Overall back seroma volumes were high, with no significant differences between control and sealant groups over 3 months. Fibrin sealant failed to reduce in situ back drainage volumes in the 10 days after surgery, and did not affect the rate or volume of seromas following drain removal.

CONCLUSION

This randomized study, which was powered for size effect, failed to show any benefit from fibrin sealant in minimizing back seromas after LD procedures.

Latissimus dorsi donor-site morbidity: the combination of quilting and fibrin sealant reduce length of drain placement and seroma rate

Seroma formation has been shown to be a multifactorial process in part due to dead space and the formation of raw surfaces, which produce large quantities of serous exudate. The purpose of this study is to evaluate the effect of quilting/progressive tension sutures (to reduce dead space) and fibrin sealant (to seal the raw surface) in combination on the seroma rate and length of drain placement in patients undergoing latissimus dorsi breast reconstruction. A retrospective review of 43 patients undergoing latissimus dorsi flap breast reconstruction was performed. The patients were divided into 2 groups: quilting sutures alone versus those with quilting sutures and fibrin sealant. Data regarding age, body mass index, smoking history, timing of reconstruction, type of breast surgery, radiation history, complications, length of drain placement, use of fibrin glue, and use of quilting/progressive tension sutures were collected for each patient. Results were analyzed statistically using unpaired t tests (P < 0.05). The quilting group included 19 patients with 24 donor sites. The mean drain placement duration was 21.5 days (range, 9-69 days). One patient in 19 developed a seroma, which was treated and resolved with aspiration. The seroma rate for the quilting only group was 5%. The quilting and sealant group included 23 patients with 26 donor sites. The quilting and sealant group had a mean duration of drain placement of 13.9 days (range, 6-38 days). This was a statistically reduced length of drainage (P = 0.04) compared with quilting only. The quilting and sealant group had 1 patient in 23 develop a seroma with a rate of 4% which compared with quilting only was not statistically significant (P = 0.4). The combination of quilting sutures and fibrin sealant directed at the 2 main mechanisms of seroma formation, (dead space and serous exudate, respectively) can decrease the duration of postoperative drain placement and does maintain low seroma rates.

Efficacy of quilting sutures and fibrin sealant together for prevention of seroma in extended latissimus dorsi flap donor sites

BACKGROUND

The extended latissimus dorsi flap is important for breast reconstruction. Unfortunately, donor site seroma is the most common complication of extended latissimus dorsi flap for breast reconstruction. Although using fibrin sealant in the donor site reduces the rate of seroma formation, donor site seroma remains a troublesome complication. The purpose of this study was to analyze the effectiveness of the combination of quilting sutures and fibrin sealant in the latissimus dorsi donor site for the prevention of seroma.

METHODS

Forty-six patients who underwent breast reconstruction with extended latissimus flap were enrolled in the study. The patients received either fibrin sealant (group 1, n=25) or a combination of fibrin sealant and quilting sutures (group 2, n=21) in the extended latissimus dorsi donor site. Outcome measures were obtained from the incidence, volume of postoperative seroma, total drainage amount, indwelling period of drainage, and duration of hospital stay.

RESULTS

The incidence of seroma was 76% in group 1 and 42.9% in group 2 (P=0.022). We also found significant reductions in seroma volume (P=0.043), total drainage amount (P=0.002), indwelling period of drainage (P=0.01), and frequency of aspiration (P=0.043). The quilting sutures did not affect the rate of drainage, tube reinsertion, or hospital stay.

CONCLUSIONS

The use of quilting sutures combined with fibrin sealant on the latissimus dorsi flap donor site is helpful for reducing the overall seroma volume, frequency of aspiration, and total drainage amount.

[Free latissimus dorsi flap transfer for reconstruction of soft tissue defects of the lower extremity]

OBJECTIVE

Sustainable and durable soft tissue coverage at the lower extremity following trauma, tumor resections, sequelae of radiation therapy or osteomyelitis using free latissimus dorsi muscle transfer is provided by a free latissimus dorsi muscle flap.

INDICATIONS

Soft tissue defects at the lower extremity following trauma, tumor resections, and sequelae of radiation therapy or osteomyelitis.

CONTRAINDICATIONS

Thoracotomy with incision of the latissimus dorsi muscle; a relative contraindication in wheelchair drivers as well as in overhead athletes due to potential diminished strength and shoulder proprioception following latissimus dorsi muscle transplantation.

SURGICAL TECHNIQUE

Under general anesthesia the patient is positioned laterally, and a substantial and meticulous debridement of the defect is performed, as is the identification and preparation of the target vessel, which is preferentially the posterior tibial artery at the calf, or more proximally the popliteal or femoral artery from the medial side as well as concomitant veins/the great saphenous vein. A tailored latissimus dorsi musculocutaneous flap is harvested with subsequent microsurgical anastomosis to the target vessel with preferential end-to-side anastomosis of the artery and end-to-end anastomosis of one or two veins.

POSTOPERATIVE MANAGEMENT

A 24-h intermediate care unit, clinical flap monitoring for at least 5-7 days, dangling of the flap using an elastic bandage for an initial 3  times  5 min starting on POD 7, compression stockings for at least 6 months subsequently.

RESULTS

From 2001-2007 75 free latissimus dorsi flaps were performed (53 ± 17 years) for soft tissue coverage at the lower extremity. In 58% the target vessel was the posterior tibial artery, in 11% the femoral artery, in 8% the anterior tibial artery and in 8% the popliteal artery. In 15% an arteriovenous (AV) loop was applied. Overall free flap survival was 95%. We encountered four total flap losses, exclusively in complex reconstructions with AV-loop situations.

The use of autologous platelet-leukocyte-enriched plasma to minimize drain burden and prevent seroma formation in latissimus dorsi breast reconstruction

INTRODUCTION

Seromas and drains are major sources of morbidity associated with latissimus dorsi breast reconstruction. Our goal was to look at an autologous platelet-leukocyte-enriched plasma spray and to assess its efficacy in reducing drain burden and seroma formation.

METHODS

We performed a single surgeon, patient-controlled, blinded study on bilateral latissimus dorsi breast reconstruction patients in which we applied autologous platelet-leukocyte-enriched plasma to one side and measured drain amounts, time to drain removal, and seroma rate.

RESULTS

Twelve patients were included in this study. The average age was 41.1 years, and the average body mass index was 21.6 kg/m. Average volume of drain output showed neither difference (789 mL spray side vs. 790 mL control side) nor average time to drain removal (11.83 days spray side vs. 11.5 days control side). There were 2 complications reported: 1 hematoma (8.33%) and 1 seroma (8.33%) that required aspiration in a postoperative visit.

CONCLUSIONS

It appears after 12 patients that there is no demonstrable difference regarding drain output, time to drain removal, or seroma incidence between the study and the control group. We feel a larger study population would add power and confirm these findings.

Effects of coagulase-negative staphylococci and fibrin on breast capsule formation in a rabbit model

BACKGROUND

The etiology and ideal clinical treatment of capsular contracture (CC) remain unresolved. Bacteria, especially coagulase-negative staphylococci, have been previously shown to accelerate the onset of CC. The role of fibrin in capsule formation has also been controversial.

OBJECTIVE

The authors investigate whether fibrin and coagulase-negative staphylococci (CoNS) modulate the histological, microbiological, and clinical outcomes of breast implant capsule formation in a rabbit model and evaluate contamination during the surgical procedure.

METHODS

Thirty-one New Zealand white female rabbits were each implanted with one tissue expander and two breast implants. The rabbits received (1) untreated implants and expanders (control; n = 10), (2) two implants sprayed with 2 mL of fibrin and one expander sprayed with 0.5 mL of fibrin (fibrin; n = 11), or (3) two implants inoculated with 100 µL of a CoNS suspension (10(8)CFU/mL-0.5 density on the McFarland scale) and one expander inoculated with a CoNS suspension of 2.5 × 10(7) CFU/mL (CoNS; n = 10). Pressure/volume curves and histological and microbiological evaluations were performed. Operating room air samples and contact skin samples were collected for microbiological evaluation. The rabbits were euthanized at four weeks.

RESULTS

In the fibrin group, significantly decreased intracapsular pressures, thinner capsules, loose/dense (<25%) connective tissue, and negative/mild angiogenesis were observed. In the CoNS group, increased capsular thicknesses and polymorph-type inflammatory cells were the most common findings. Similar bacteria in capsules, implants, and skin were cultured from all the study groups. One Baker grade IV contracture was observed in an implant infected with Micrococcus spp.

CONCLUSIONS

Fibrin was associated with reduced capsule formation in this preclinical animal model, which makes fibrin an attractive potential therapeutic agent in women undergoing breast augmentation procedures. Clinical strategies for preventing bacterial contamination during surgery are crucial, as low pathogenic agents may promote CC.
