Comparative analysis on the effect of low-thermal plasma dissection device (PEAK PlasmaBlade) vs conventional electrosurgery in post-bariatric abdominoplasty: A retrospective randomised clinical study

PlasmaBlade versus Electrocautery for Deep Inferior Epigastric Perforator Flap Harvesting in Autologous Breast Reconstruction: A Comparative Clinical Outcome Study

(1) Background: DIEP-based breast reconstruction necessitates wide undermining at the abdominal donor site, creating large wound areas. Flap harvesting is usually conducted using electrosurgical dissection devices. This study sought to compare the clinical outcomes in patients after using the PEAK PlasmaBlade (PPB) versus monopolar electrocautery (MPE). (2) Methods: This retrospective cohort study included 128 patients with DIEP-based breast reconstruction. Patient characteristics and information on the postoperative course were collected and a comparative evaluation was conducted. (3) Results: The MPE group exhibited significantly (p* = 0.0324) higher abdominal drainage volume (351.11 ± 185.96 mL) compared to the PPB group (279.38 ± 183.38 mL). A subgroup analysis demonstrated that PPB significantly reduced postoperative wound fluid in patients with BMI > 30 kg/m2 (p* = 0.0284), without prior neoadjuvant chemotherapy (p** = 0.0041), and among non-smokers (p = 0.0046). Furthermore, postoperative pain was significantly (p**** < 0.0001) lower in the PPB cohort. (4) Conclusions: This study confirms the non-inferiority of the PEAK PlasmaBlade to conventional electrocautery for abdominal flap harvesting. The PPB demonstrated advantages, notably reduced drainage volume and lower postoperative pain levels. Recognizing patient subsets that benefit more from the PPB highlights the importance of personalized device selection based on patient characteristics.

Dissection using pulsed radiofrequency energy device (PlasmaBlade) is safe and efficient in experimental revision neuromodulation implant surgery

BACKGROUND

The use of functional neurosurgical implants has increased over the past 10 years. PlasmaBlade is an innovative electrosurgical appliance harnessing pulsed radiofrequency (RF) energy. Our aim was to assess the risk of damage to neuromodulation hardware during PlasmaBlade dissection.

MATERIALS AND METHODS

A simulated setting with chicken breast threaded with different hardware and PlasmaBlade used in three configurations. . Post dissection, the wires were inspected naked eye and under an operating microscope. The induced current was assessed contemporaneously using an oscilloscope.

RESULTS

Five surgeons tested the PlasmaBlade at different generator settings. Sixty dissections were undertaken. No structural damage or induced current was identified at CUT 3/4, COAG 5. At CUT 6, COAG 5 and during dissection in a perpendicular orientation with prolonged hardware contact, opacification of insulation material occurred in 15/20 dissections. There was no dissolution of insulation even at this setting. On deviation from Medtronic advice, hardware damaged occurred if one was reckless with the PlasmaBlade.

CONCLUSION

When using the recommended settings and operational technique, PlasmaBlade dissection did not cause any damage to implant wiring/tubing in this simulated setting. This report seeks to add to clinical data suggesting PlasmaBlade is safe for dissection around deep brain stimulator (DBS), vagal nerve stimulator (VNS), and spinal cord stimulator (SCS) hardware.

Decreasing Seroma Incidence Following Abdominoplasty: A Systematic Review and Meta-Analysis of High-Quality Evidence

Background

Seroma formation is the most common complication of abdominoplasties. Many preventive interventions have been proposed, but none have been recognized as a definitive solution, partly due to varying levels of evidence (LOE) in the literature.

Objectives

We aimed to analyze seroma prevention methods supported by high-level evidence.

Methods

The PubMed database was queried through August 2023. Primary articles of interest included randomized controlled trials (RCTs), prospective comparative studies, and meta-analyses of these studies. The LOE for each article was determined according to the American Society of Plastic Surgeons Rating Scale. The "seroma occurrence ratio," or ratio of seroma events in the interventional group to respective control group, was calculated to compare incidence rates between techniques.

Results

Twenty articles and 9 categories of techniques were analyzed. Study designs included 10 RCTs, 2 prospective cohort studies, 7 prospective comparative studies, and 1 retrospective randomized study. The use of progressive-tension and quilting sutures had the most data supporting a statistically significant reduction in seroma (occurrence ratio 0.306, P < .001). Tissue adhesives and preservation of Scarpa's fascia were also well reinforced (0.375, P < .01 and 0.229, P < .011, respectively), while increasing the number of drains was not (P = .7576). Meta-analysis demonstrated that compared with 2 drains alone, alternative techniques were more effective at reducing seroma occurrence (pooled risk ratio 0.33, 95% CI, 0.11-0.99).

Conclusions

This review highlights multiple seroma prevention techniques for abdominoplasty investigated in recent high-quality literature. We suggest future randomized comparative studies of the various seroma prevention methods to fully ascertain their efficacy following abdominoplasty.

Use of PEAK PlasmaBlade in implant-based breast reconstruction and radiotherapy: new strategy to reduce complications

BACKGROUND

Implant-based breast reconstruction in the setting of radiotherapy often leads to higher complications rates (mainly capsular contracture and wound dehiscence) and poor cosmetic outcomes. We hypothesized that the combination of pulsed-electron avalanche knife (PEAK) PlasmaBlade (a pulsed radiofrequency electrosurgery) and acellular dermal matrix Veritas® in postmastectomy radiotherapy implant-based breast reconstruction could result in lower complications rate, better reconstructive results, and patient satisfaction.

METHODS

A prospective observational study focused on the use of PEAK PlasmaBlade in implant-based breast reconstruction and radiotherapy was carried out in the Plastic Reconstructive Surgery Unit at Fondazione IRCCS Istituto Nazionale Tumori Milano between December 2017 and 2019 (2017-2018: enrollment; 2018-2019: follow-up). Patient demographics were queried and complication rates and patient and surgeon satisfaction were assessed.

RESULTS

A total of 88 patients were enrolled; 2 patients received bilateral reconstruction, leading to a total of 90 procedures. Sixty-two women received contralateral symmetrization. Seroma was the most frequent minor complication (8.8%); implant exposure was the most recorded among major complications (5.5%). Preoperative lipofilling was the most substantial protective factor for preventing complications (p < 0.001). A significant association between capsular thermal damage thickness and the type of electrosurgery used (traditional electrosurgery vs PEAK PlasmaBlade) was observed, with lower values with PEAK PlasmaBlade (p < 0.0001).

CONCLUSIONS

Our protocol results in low rates of surgical complications and a high level of patient and surgeon satisfaction although longer follow-up is needed.

Post-Bariatric Plastic Surgery: Abdominoplasty, the State of the Art in Body Contouring

Due to the increased prevalence of obesity in the last decades, bariatric surgery has been on the rise in recent years. Bariatric surgery is a compelling option for weight loss in obese patients with severe obesity-related comorbidities or for whom lifestyle modifications have proven ineffective. Redundant skin following significant weight loss is a common occurrence affecting up to 96% of patients who undergo bariatric surgery, negatively impacting physical and psychosocial health and detracting from activities of daily living. Statistics of the American Society of Plastic Surgeons show that 46,577 body contouring procedures were performed after massive weight loss in the USA in a 2020 report. Abdominoplasty, a well-established cosmetic surgery procedure for improving body contour, is performed by removing excess skin and fat from the abdominal wall and thereby restoring musculofascial integrity and skin elasticity, resulting in a more ideal body shape and increasing quality of life. Although abdominoplasty is a safe procedure, it has been associated with a higher complication rate compared with other body-contouring procedures. Technologic advances over the past decade have been developed as non-invasive alternatives or adjunctive tools to surgery to enhance cosmetic results and minimize complications. New energy-based technologies may supplant invasive surgery for mild to moderate skin laxity and/or diminish the extent of surgery and resulting scars. Plastic surgeons play a significant role in improving the quality of life of patients who suffer from obesity and underwent bariatric surgery. We are deeply convinced, however, that the advancement of knowledge and research in this field will determine the introduction of new technologies and custom-made techniques. This advancement will reduce the complication rate with a rapid reintegration of the patient into the world of work and resumption of daily activities.

The Global Prevalence of Seroma After Abdominoplasty: A Systematic Review and Meta-Analysis

BACKGROUND

Abdominoplasty is one of the most common cosmetic surgeries performed worldwide. Seroma is also the most common local complication associated with abdominoplasty, which increases care costs, reduces patient satisfaction, and has serious complications for patients. Results of previous studies report different levels of seroma prevalence after abdominoplasty. The aim of this study is to standardize the statistics of the prevalence of seroma after abdominoplasty using meta-analysis.

METHODS

In this systematic review and meta-analysis study, data from studies conducted on the global prevalence of seroma after abdominoplasty was extracted using the keywords "Prevalence, Epidemiology, Complications, Abdominoplasty, Seroma, and Lipo abdominoplasty" in the databases of Science, Scientific Information Database, MagIran, Embase, Scopus, PubMed, Web of Science, and Google Scholar search engine without time limit until October 2020. The random-effects model was used to analyze the eligible studies, and the heterogeneity of the studies was investigated with the I² index. Data analysis was performed using Comprehensive Meta-Analysis software (Version 2).

RESULTS

In reviewing 143 studies (five studies related to Asia, 55 studies related to Europe, three studies related to Africa, and 80 studies related to the Americas) with a total sample size of 27834 individuals, the global prevalence of seroma after abdominoplasty was obtained as 10.9% (95% CI: 9.3-3.6.6%) and the highest prevalence of seroma was related to the Europe continent with 12.8% (95% CI: 10.15-3.9%). The results from meta-regression showed a declining trend in the global prevalence of seroma after abdominoplasty with an increase in the sample size, age of study participants, and the year of study (p < 0.05).

CONCLUSIONS

This study shows that the prevalence of seroma after abdominoplasty is high globally. Therefore, physicians and specialists must consider its importance and take the controlling and treatment measures seriously.

Comparative healing of swine skin following incisions with different surgical devices

Background

Electrosurgical technology is widely used in surgical dissection and hemostasis, but the generated heat creates thermal injury to adjacent tissues and delays wound healing. The plasma blade (PB) applies pulsed radiofrequency (RF) to generate electrical plasma along the edge of a thin, flat, insulated electrode, minimizing collateral tissue damage. This study aimed to evaluate wound healing in swine skin following incision with a new surgical system that applies low-temperature plasma (NTS-100), a foreign PB, conventional electrosurgery (ES), and a scalpel blade.

Methods

In vitro porcine skin and an in vivo porcine skin model were used in this study. Full-thickness skin incisions 3 cm in length were made on the dorsum of each animal for each of the 5 surgical procedures at 0, 21, 28, 35, and 42 days. The timing of the surgical procedures allowed for wound-healing data points at 1, 2, 3, and 6 weeks accordingly. Local operating temperature and blood loss were quantified. Wounds were harvested at designated time points, tested for wound tensile strength, and examined histologically for scar formation and tissue damage.

Results

Local operating temperature was reduced significantly with NTS-100 (cut mode 83.12±23.55 °C; coagulation mode 90.07±10.6 °C) compared with PB (cut mode 94.46±11.48 °C; coagulation mode 100.23±6.58 °C, P<0.05) and ES (cut mode 208.99±34.33 °C, P<0.01; coagulation mode 233.37±28.69 °C, P<0.01) in vitro. Acute thermal damage from NTS-100 was significantly less than ES incisions (cut mode: 247.345±42.274 versus 495.295±103.525 µm, P<0.01; coagulation mode: 351.419±127.948 versus 584.516±31.708 µm, P<0.05). Bleeding, histological scoring of injury, and wound strength were equivalent for the NTS-100 and PB incisions.

Conclusions

The local operating temperature of NTS-100 was lower than PB, and NTS-100 had similarly reliable safety and efficacy.

Dissection Technique for Abdominoplasty With Scarpa Fascia Preservation: Comparative Study on Avulsion Technique Versus Diathermocoagulation

BACKGROUND

Many strategies have been developed to lower the high complication rate associated with a full abdominoplasty. The dissection technique may have a role to achieve this goal.

OBJECTIVES

The present study compared 2 different dissection techniques to perform a full abdominoplasty with Scarpa fascia preservation: avulsion technique and electrodissection.

METHODS

A retrospective observational cohort study was performed in 2 health institutions from January 2005 to January 2019. A total of 251 patients were involved: 122 patients submitted to abdominoplasty employing the avulsion technique (Group A) and 129 with diathermocoagulation (coagulation mode) (Group B). The latter was further divided into group B1 (57 patients with device settings according to surgeon's preferences) and B2 (72 patients with a specific regulation aiming at minimal tissue damage). Several variables were analyzed: population characteristics, time of hospital stay, time to drain removal, total and daily drain output, emergency department visits, readmission, reoperation, and local and systemic complications.

RESULTS

The general characteristics of both groups did not statistically significantly differ except for previous abdominal surgery. The diathermocoagulation group had a significantly lower length of hospital stay and time to drain removal. Moreover, these advantages were maximized when electrocautery was conducted with a specific low-voltage setting as significant differences were found. The other outcomes were identical.

CONCLUSIONS

Limiting the extension of electrodissection with the avulsion technique did not present any advantage. Utilizing diathermocoagulation (coagulation mode) during a full abdominoplasty with Scarpa fascia preservation, especially when it is aimed at minimal tissue damage, reduces patients' time with drains.

A Retrospective Study of Coronary Artery Bypass Grafting with Low-Thermal Plasma Dissection Device Compared to Conventional Monopolar Electrosurgery

Introduction:

The objective of this study is to compare the effects of conventional monopolar electrosurgery (CMES) and low-thermal plasma kinetic cautery (PKC) on complications such as bleeding, abnormal wound healing, pain, and drainage in patients who underwent on-pump coronary artery bypass grafting (CABG).

Methods:

This retrospective clinical study included 258 patients undergoing CABG; the patients were randomized to PKC (PEAK PlasmaBlade, n=153) and CMES (n=105) groups. The patients’ clinical data were examined retrospectively for biochemical variables, postoperative drainage, post-surgery erythrocyte suspension transfusion count, surgical site pain examined with visual analogue scale (VAS), and wound healing. Two-sided P-value > 0.05 was considered as statistically significant.

Results:

The median post-surgery erythrocyte suspension transfusion number was significantly lower with PKC compared to CMES (0 [0-1] vs. 1 [1-4], respectively, P<0.001). Mean postoperative drain output and time until removal of drain tubes were significantly lower with PKC compared to CMES (300±113 vs. 547±192 and 1.95±1.5 vs. 2.44±1.8; P<0.001 and P=0.025, respectively). Mean VAS score for spontaneous and cough-induced pain were significantly lower with PKC compared to CMES (1.98±1.51 vs. 3.94± 2.09 and 3.76±1.46 vs. 5.6±1.92; P<0.001 for both comparisons). Reoperation due to bleeding was significantly higher with CMES compared to PKC (0 vs. 11 [7.2%], P=0.001).

Conclusion:

Use of PKC during CABG considerably reduces postoperative drainage, need for blood transfusion, reoperation due to bleeding, and postoperative pain. PCK appears to be a good alternative to CMES for CABG.

Effect of low-thermal dissection device versus conventional electrocautery in mastectomy for female-to-male transgender patients

Subcutaneous mastectomy, the first step in sexual reassignment surgery of female-to-male transsexuals, is associated with high rates of complication and revision surgery. Also, conventional electrosurgery and the associated thermal tissue damage may compromise outcome. This retrospective randomised clinical study evaluated the effect of low-thermal plasma dissection device (PEAK PlasmaBlade, Medtronic, Minneapolis, Minnesota) in comparison with conventional electrosurgery. A total of 17 female-to-male transsexuals undergoing mastectomy were randomised to PEAK PlasmaBlade on one breast side and to monopolar electrosurgery on the other side of the same patient. Wounds of 17 patients were examined histologically for acute thermal injury. Significantly less total volume of drain output (58.8 ± 37.4 mL vs 98.5 ± 76.4 mL; P = .012) was found on the PEAK PlasmaBlade side compared with the electrosurgery side. Duration of drain was significantly shorter on the PEAK PlasmaBlade side (2.5 ± 0.7 days vs 3.2 ± 0.6 days; P = .010). Furthermore, the PEAK PlasmaBlade side showed fewer thermal damages (41.2% vs 82.4%; P = .039) and thermal injury depth from PEAK PlasmaBlade side was less (3170 vs 4060 μm). PEAK PlasmaBlade appears to be superior to monopolar electrosurgery for mastectomy in female-to-male transsexuals, because it demonstrated less thermal tissue damage, less total volume of drain output, and shorter duration of drain, resulting in faster wound healing.

Comparative analysis on the effect of low-thermal plasma dissection device (PEAK PlasmaBlade) vs conventional electrosurgery in post-bariatric abdominoplasty: A retrospective randomised clinical study

Post-bariatric patients undergoing abdominoplasty have a relatively high risk of complications due to residual obesity and major comorbidities. Also, conventional electrosurgery and the associated thermal tissue damage may compromise outcomes. This retrospective randomised clinical study evaluated the effect of low-thermal plasma dissection device (PEAK [pulsed electron avalanche knife] PlasmaBlade) in comparison with conventional electrosurgery. A total of 52 post-bariatric patients undergoing abdominoplasty were randomised to PEAK PlasmaBlade (n = 26) and to monopolar electrosurgery (n = 26). Wounds of 20 patients per group were examined histologically for acute thermal injury depth. In PEAK PlasmaBlade incisions, acute thermal damage was significantly reduced compared with standard of care (40% vs 75%; P = .035). Also, acute thermal injury depth from PEAK PlasmaBlade was less than that from electrosurgery (2780 μm vs 4090 μm). Significantly less total complication rate (30.8% vs 69.2%; P = .012) was found by PEAK PlasmaBlade compared with electrosurgery. Moreover, the PEAK PlasmaBlade showed less than half as many wound healing problems (19.2% vs 46.2%; P = .075), far fewer secondary bleeding (7.7% vs 30.8%; P = .075), and no seroma compared with four seroma with the standard of care (0% vs 15.4%; P = .11). PEAK PlasmaBlade appears to be superior to traditional monopolar electrosurgery for post-bariatric abdominoplasty, because it demonstrated significantly less tissue damage, less total complication rate, and fewer postoperative seroma resulting in faster wound healing.
