RESUMO

ABSTRACT: With the rapid development of medical technology, the use of electrosurgical instruments is dramatically increased in various types of surgery. However, the damage of the insulation layer of the reusable electrosurgical instrument often causes surgical accidents. The procedures of packaging and cleaning contribute to many damages to insulating layer of reusable electrosurgical instruments.Various types of reusable electrosurgical instruments were detected for insulation failures, conduction failures, short-circuit by using a high-voltage detector, DIATEG (Morgate company). In addition, reusable electrosurgical instruments were detected for insulation failures after packaging and cleaning by different procedures.13.1% (129/740) electrosurgical instruments had an insulation test failure; 6.2% (9/146) monopolar wires were with conduction failure; and 7.7% (16/207) bipolar wires were with short-circuit. Different packaging and cleaning procedures contribute to various degrees of damages to insulating property of reusable electrosurgical instruments.Insulation failure was a wide problem of reusable electrosurgical instruments, while fixed packaging method and mild cleaning procedures result in fewer damages to insulating property of reusable electrosurgical instruments.

RESUMO

BACKGROUND: The various techniques of upper blepharoplasty have been compared based on surgical time to perform the procedure, postoperative healing, scar cosmesis, and cost. Few studies have evaluated the histology of the excised tissue, and no study has compared the tissue histology of 3 blepharoplasty methods using scalpel, microdissection needle with electrocautery, and CO2 laser excision in the same patient. OBJECTIVE: To evaluate the histologic changes of tissue after removal of upper eyelid skin using scalpel incision, microdissection electrocautery needle, and CO2 laser. METHODS: Upper blepharoplasty skin excisions were examined from specimens obtained using scalpel incision, microdissection needle tip with electrocautery, and CO2 continuous wave beam. The specimens were sent for permanent sections for histologic evaluation. RESULTS: The skin that was removed using cold steel scalpel incision showed no cellular necrosis or heat artifact. The tissue treated with the CO2 laser demonstrated significant thermal injury, including loss of cellular polarity, keratinocyte necrosis, and separation of the epidermis from the basement membrane. The skin excised using the electrocautery microdissection needle demonstrated fulguration artifact, including spindling of the epidermal nuclei with palisading of the keratinocytes. Necrosis was not prominent in the electrocautery microdissection needle specimens. CONCLUSION: The amount of histologic tissue injury was greatest in the skin treated with continuous wave CO2 laser, followed by the microdissection needle with electrocautery. The cold steel scalpel incision showed no cellular necrosis.

RESUMO

AIMS: The electrosurgical technology category is used widely, with a diverse spectrum of devices designed for different surgical needs. Historically, hospitals are supplied with electrosurgical devices from several manufacturers, and those devices are often evaluated separately; it may be more efficient to evaluate the category holistically. This study assessed the health economic impact of adopting an electrosurgical device-category from a single manufacturer. METHODS: A budget impact model was developed from a U.S. hospital perspective. The uptake of electrosurgical devices from EES (Ethicon Electrosurgery), including ultrasonic, advanced bipolar, smoke evacuators, and reusable dispersive electrodes were compared with similar MED (Medical Energy Devices) from multiple manufacturers. It was assumed that an average hospital performed 10,000 annual procedures 80% of which involved electrosurgery. Current utilization assumed 100% MED use, including advanced energy, conventional smoke mitigation options (e.g. ventilation, masks), and single-use disposable dispersive electrode devices. Future utilization assumed 100% EES use, including advanced energy devices, smoke evacuators (i.e. 80% uptake), and reusable dispersive electrodes. Surgical specialties included colorectal, bariatric, gynecology, thoracic and general surgery. Systematic reviews, network meta-analyses, and meta-regressions informed operating room (OR) time, hospital stay, and transfusion model inputs. Costs were assigned to model parameters, and price parity was assumed for advanced energy devices. The costs of disposables for dispersive electrodes and smoke-evacuators were included. RESULTS: The base-case analysis, which assessed the adoption of EES instead of MED for an average U.S. hospital predicted an annual savings of $824,760 ($101 per procedure). Savings were attributable to associated reductions with EES in OR time, days of hospital stay, and volume of disposable electrodes. Sensitivity analyses were consistent with these base-case findings. CONCLUSIONS: Category-wide adoption of electrosurgical devices from a single manufacturer demonstrated economic advantages compared with disaggregated product uptake. Future research should focus on informing comparisons of innovative electrosurgical devices.

RESUMO

To assess the feasibility of needle tract ablation in liver tissue in ex vivo and in vivo animal models using a cryo-probe and electrosurgical device. The experimental device is made by inserting a cryoprobe through an intro-ducer sheath for insulation, with 2-cm of probe tip projecting out. A beagle liver was punctured by the device, and electric current was applied at 30-W with the electrosurgical knife touching the non-insulated device base. The discolored area of cut surface along the device was evaluated in 5 application-time groups (5 , 10 , 15 , 20, or 25 seconds). An ex vivo experiment was performed to determine an ablation algorithm with an appropriate application time by comparison with radiofrequency ablation (RFA) results. Thereafter, an in vivo experiment was performed to verify the algorithm's feasibility. In the ex vivo model, the cut surface demonstrated different amounts of discolored area according to the application time. The total discolored area in the 20-seconds group was similar to that by RFA. In the in vivo model, the liver did not bleed, the total discolored area was similar to that ex vivo, and coagulation necrosis was confirmed by photomicrograph. Needle tract ablation can be per-formed using the experimental device and electrosurgical device.

RESUMO

PURPOSE: The pulsed-electron avalanche knife (PEAK) PlasmaBlade TnA (Medtronic, n.d.) is a relatively new electrosurgical technology that is used widely in head and neck surgery (Medtronic Manuals, n.d.). This study aims to summarize device malfunctions, patient complications, and subsequent interventions related to PEAK PlasmaBlade TnA during tonsillectomy and adenoidectomy. MATERIALS AND METHODS: The US Food and Drug Administration's Manufacture and User Facility Device Experience database was queried for reports of PlasmaBlade TnA adverse events from June 6, 2009, to August 30, 2020. Data were extracted from reports pertaining to tonsillectomy with or without adenoidectomy. RESULTS: 128 reports were identified, from which 163 adverse events were extracted. Of these, 23 (14.6%) were related to patients, and 140 (85.4%) were related to device malfunction. The most frequently reported patient-related adverse event was a burn injury (17 [73.9%]). The most common device malfunctions were dislodgment of device component (39 [27.9%]), followed by tip ignition (32 [22.9%]), damaged tip or wire during operation (28 [20%]), and melted device (24 [17.1%]). CONCLUSIONS: PEAK PlasmaBlade TnA have demonstrated utility in tonsillectomy with or without adenoidectomy but are associated with adverse events. Interventions aimed at improving both physician and patient education may help reduce adverse events attributed to improper use. Further study is needed to clarify optimal approaches to education.

RESUMO

Three electrosurgical tissue-sealing devices (EnSeal ETSDRC-01, LigaSure LS1500 and Thunderbeat TB-0535PC) were compared regarding sealing time (ST), maximum working temperature (WTmax) and the total (MTZtotal) as well as the collateral microscopic thermal injury zone (MTZcollat) using laparoscopic handpieces 5 mm in diameter on four types of tissue (liver, mesentery, cross striated muscle and spleen) in an in vivo porcine model. LigaSure had the lowest mean ST in spleen, mesentery, muscle and liver, followed by Thunderbeat and EnSeal with significant differences between all types of tissues and devices. The significantly lowest mean WTmax was obtained for EnSeal in mesentery, muscle and liver. LigaSure and EnSeal operated at the lowest temperature in spleen without a significant difference between them. Thunderbeat produced significantly higher temperature peaks in all cases. The lowest mean MTZtotal was caused by LigaSure and EnSeal in spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Nevertheless, Thunderbeat produced the significantly lowest mean MTZtotal in the liver. EnSeal produced the lowest mean MTZcollat in the liver, followed by LigaSure and Thunderbeat showing significant differences. EnSeal and LigaSure produced the lowest mean MTZcollat in the spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Based on the results of this study, Thunderbeat seems to be more invasive to tissue integrity (even without the activation of the ultrasonic scissor function) than EnSeal or LigaSure, that operate at lower temperatures and were found to cause negligible collateral thermal damage.

RESUMO

OBJECTIVE: Adenocarcinoma in situ (AIS) of the cervix is a precursor to cervical adenocarcinoma. When AIS is detected by cervical screening an excision biopsy is mandatory to exclude invasion. We aimed to compare margins status, specimen size and fragmentation after loop electrosurgical excision procedure (LEEP) and 'cold knife cone biopsy' (CKC). METHODS: The EXCISE Trial was an investigator-initiated, multicenter, open-label, parallel-group, phase 2, randomized study. Patients were enrolled at seven hospitals in Australia and New Zealand. We randomly assigned women aged ≥18 to ≤45 years with screen detected AIS to LEEP or CKC. Co-primary endpoints were margin status, specimen size and fragmentation. Analysis was by intention-to-treat. RESULTS: Between August 2, 2017 and September 6, 2019, 40 patients were randomly assigned 2:1 to LEEP or CKC. Margin status was evaluable in 36 cases. The proportion of patients with involved margins did not differ between groups. 25 of 26 LEEP and all 14 CKC biopsies were excised as single specimens (p = 1·00). There were no differences in specimen dimensions. Patients in the CKC group had more post-operative complications (64.3% compared to 15.4% for LEEP p = ·00). There were no differences in grade three complications (p = ·65). CONCLUSIONS: LEEP was not associated with a greater likelihood of positive margins, specimen fragmentation or smaller excision compared to CKC when performed according to a standardized protocol. However, the study was not powered to establish non-inferiority of LEEP and a definitive phase 3 trial to compare margin status and rates of treatment failure after LEEP and CKC is warranted.

RESUMO

OBJECTIVE: Conization aims to remove pre-neoplastic lesions of the uterine cervix. Several techniques for conization have been compared, but evidence regarding the most effective therapeutic option is scant. Here, we aimed to compare the recurrence rate following laser conization and loop electrosurgical excision procedure (LEEP) in patients with high-grade cervical dysplasia (HSIL/CIN2+). METHODS: This is a retrospective multi-institutional study. Medical records of consecutive patients with HSIL/CIN2+ undergoing conization between 2010 and 2014 were retrieved. A propensity-score matching (PSM) was applied in order to reduce allocation bias. The risk of developing recurrence was estimated using Kaplan-Meir and Cox hazard models. RESULTS: Overall, 2966 patients had conization over the study period, including 567 (20%) and 2399 (80%) patients having laser conization and LEEP, respectively. Looking at predictors of recurrence, diagnosis of CIN3 (HR:3.80 (95%CI:2.01,7.21); p < 0.001) and HPV persistence (HR:1.81 (95%CI:1.11,2.96); p < 0.001) correlated with an increased risk of recurrence. After applying a PSM we selected 500 patients undergoing laser conization and 1000 undergoing LEEP. Patients undergoing LEEP were at higher risk of having positive surgical margins in comparison to patients undergoing laser conization (11.2% vs. 4.2%). The risk of having persistence of HPV was similar between the two groups (15.0% vs. 11.6%;p = 0.256). Five-year recurrence rate was 8.1% and 4% after LEEP and laser conization, respectively (p = 0.023). HPV persistence was the only factor associated with [5-]year recurrence after both laser conization (p = 0.003) and LEEP (p = 0.001). CONCLUSIONS: HPV persistence is the only factor associated with an increased risk of recurrence after either laser conization or LEEP. Owing to the lack of data regarding obstetrical outcomes, we are not able to assess the best therapeutic option for women with cervical dysplasia.

RESUMO

STUDY DESIGN: Prospective 2-year study with operative sampling and in-vitro analysis of chromium ions following spinal surgery in children. OBJECTIVES: To measure metal ion levels at preoperative, intraoperative, and postoperative times to determine patterns of metal ion release during instrumented spinal surgery. SUMMARY OF BACKGROUND DATA: Raised serum metal ion levels are reported following instrumented spinal fusion in adolescent idiopathic scoliosis. The authors noted raised chromium levels in patients receiving implants that did not contain chromium. This prompted further work to establish the source. The electrosurgery tips used were discovered to contain 17% chromium. METHODS: Chromium, cobalt, and titanium levels were measured before, during, and after surgery in serum and local intraoperative fluid samples in 11 children undergoing posterior instrumentation for scoliosis. Administered drugs, cell-saver fluids, and intraoperative fluids, both local and intravenous, were investigated to exclude these as sources of chromium ions. An in-vitro study was also performed to elucidate sources of intraoperative chromium ions. RESULTS: High chromium levels were detected in all samples from the wound irrigation fluid prior to insertion of metal implants. Immediate postoperative chromium serum ion levels were also elevated and returned to baseline by day 30. In-vitro sampling of fluids from test models using electrosurgery revealed high levels of chromium ions CONCLUSION.: This finding of high chromium metal ion concentrations in intraoperative and early postoperative samples provides evidence of chromium release during the dissection phase of spinal surgery. This challenges existing beliefs that metal ion release occurs solely due to implants and now implicates the electrosurgery electrode tips as a source of raised chromium ion levels. Thorough irrigation of the operative site after the dissection phase of surgery to both dilute and reduce the intraoperative chromium ion load is suggested. Alternative electrosurgery electrode tips or other methods to coagulate during surgery could be considered. LEVEL OF EVIDENCE: 2.

RESUMO

BACKGROUND: In the COVID-19 crisis, laparoscopic surgery is in focus as a relevant source of bioaerosol release. The efficacy of electrostatic aerosol precipitation (EAP) and continuous aerosol evacuation (CAE) to eliminate bioaerosols during laparoscopic surgery was verified. STUDY DESIGN: Ex-vivo laparoscopic cholecystectomies (LCs) were simulated ± EAP or CAE in Pelvitrainer equipped with swine gallbladders. Release of bioaerosols was initiated by performing high-frequency electrosurgery with a monopolar electro hook (MP-HOOK) force at 40 watts (MP-HOOK40) and 60 watts (MP-HOOK60), as well as by ultrasonic cutting (USC). Particle number concentrations (PNC) of arising aerosols were analyzed with a condensation particle counter (CPC). Aerosol samples were taken within the Pelvitrainer close to the source, outside the Pelvitrainer at the working trocar, and in the breathing zone of the surgeon. RESULTS: Within the Pelvitrainer, MP-HOOK40 (6.4 × 105 cm-3) and MP-HOOK60 (7.3 × 105 cm-3) showed significantly higher median PNCs compared to USC (4.4 × 105 cm-3) (p = 0.001). EAP led to a significant decrease of the median PNCs in all 3 groups. A high linear correlation with Pearson correlation coefficients of 0.852, 0.825, and 0.759 were observed by comparing MP-HOOK40 (± EAP), MP-HOOK60 (± EAP), and USC (± EAP), respectively. During ex-vivo LC and CAE, significant bioaerosol contaminations of the operating room occurred. Ex-vivo LC with EAP led to a considerable reduction of the bioaerosol concentration. CONCLUSIONS: EAP was found to be efficient for intraoperative bioaerosol elimination and reducing the risk of bioaerosol exposure for surgical staff.

RESUMO

BACKGROUND: Smoke is generated by energy-based surgical instruments. The airborne by-products may have potential health implications. METHODS: We developed a simple way to use de conventional surgical evacuator coupled with de electrosurgical pen attached to a 14G bladder catheter for open surgery. It was used in ten prospective patients with breast cancer. RESULTS: We notice a high reduction in surgical smoke during all breast surgery. A questionnaire was used for all participants of the surgery to answer the impression that they had about the device. The subjective impression was that the surgical smoke in contact whit the surgical team was reduced by more than 95%. CONCLUSIONS: Surgical smoke is the gaseous by-product produced by heat-generating devices in various surgical procedures. Surgical smoke may contain chemicals particles, bacteria, and viruses that are harmful and increase the risk of infection for surgeons and all the team in the operation room due to long term exposure of smoke mainly in coronavirus disease 2019 age. The adapted device described is a very simple and cheaper way to use smoke evacuators attached with the monopolar electrosurgical pen to reduce smoke exposure to the surgical team worldwide.

RESUMO

INTRODUCTION: The SAGES Fundamental Use of Surgical Energy (FUSE) program accompanied by a bench-top simulation has shown to improve knowledge of the safe use of energy devices. However, there are significant barriers and costs associated with delivering an effective structured simulation curriculum to a widespread international audience. The purpose of this study was to evaluate if bench-top simulation FUSE curriculum through telementoring is as effective as a live-in house proctor for electrosurgical training. METHODS: A two-armed multi-institutional randomized controlled trial was designed, including a 1-h didactic electrosurgery course (FUSE curriculum), followed by a structured 1-h bench-top simulation training session. For the simulation, participants were randomized to either a live proctor who delivered the course on-site (LIVE group), or a proctor from a remote location using videoconferencing platform (TELEM group). Pre- and post-curriculum (immediate and 6 months) knowledge and self-perceived comfort and competence were assessed. Data are expressed as median [interquartile range], *p < 0.05. RESULTS: Sixty-five (35 LIVE; 30 TELEM) surgical trainees from three institutions participated. Baseline characteristics were similar. Total score on the exam improved from 47% [40-54] to 78% [71-84]* amongst all participants, with similar immediate post-curriculum scores in the LIVE group compared to the TELEM group (77% [69-83] vs 80% [75-85]). At 6 months, performance on the exam declined significantly for both groups, but remained similar between the two (LIVE: 59% [51-71] vs TELEM: 71% [57-77]). Participants in both groups reported feeling greater comfort and competence post-curriculum (immediate and at 6 months) compared to baseline, with no difference between the two groups. CONCLUSION: A bench-top simulation FUSE course delivered via a telementoring platform seems to improve surgical trainees' knowledge and comfort in the safe use of electrosurgical devices as effectively as when it is delivered by a live proctor, despite long-term decay for both methods.

RESUMO

BACKGROUND: Postacne scars have significant psychosocial distress among patients. Subcision is a well-known treatment modality specially for rolling type of acne scars, but is a crude mechanical process, which carries a risk of hematoma formation. AIMS: To compare the efficacy and safety of radiofrequency-assisted subcision (rSubcision) with conventional subcision in postacne scars. METHODS: In this randomized, split-face study, adult patients with postacne scars were randomized to receive either conventional subcision or rSubcision in 2 sessions, 4 weeks apart and followed up for 2 months. Outcome was measured using Goodman and Baron score (GBS), investigator global assessment (IGA) by two blinded dermatologists, and patient global assessment (PGA). RESULTS: Seventeen out of 21 patients completed the treatment. Statistical analysis of the results was performed using SPSS 15.0 statistical software (SPSS). Patients in both the groups had significant improvement from baseline according to quantitative scoring (P = .0001), number of scars (P = .0001), IGA, and PGA. The improvement was comparable in both the groups according to GBS and IGA but better on rSubcision side in terms of PGA. Two patients developed small entry point burn during rSubcision which healed in one month and one developed persistent hematoma with conventional subcision. CONCLUSIONS: Both modalities were comparable in terms of assessment scores and investigator assessment, but patients found improvement better on rSubcision side.

RESUMO

BACKGROUND & AIMS: There is debate over the type of electrosurgical setting that should be used for polyp resection. Some endoscopists use a type of blended current (yellow), whereas others prefer coagulation (blue). We performed a single-blinded, randomized trial to determine whether type of electrosurgical setting affects risk of adverse events or recurrence. METHODS: Patients undergoing endoscopic mucosal resection of nonpedunculated colorectal polyps 20 mm or larger (n = 928) were randomly assigned, in a 2 × 2 design, to groups that received clip closure or no clip closure of the resection defect (primary intervention) and then to either a blended current (Endocut Q) or coagulation current (forced coagulation) (Erbe Inc) (secondary intervention and focus of the study). The study was performed at multiple centers, from April 2013 through October 2017. Patients were evaluated 30 days after the procedure (n = 919), and 675 patients underwent a surveillance colonoscopy at a median of 6 months after the procedure. The primary outcome was any severe adverse event in a per patient analysis. Secondary outcomes were complete resection and recurrence at first surveillance colonoscopy in a per polyp analysis. RESULTS: Serious adverse events occurred in 7.2% of patients in the Endocut group and 7.9% of patients in the forced coagulation group, with no significant differences in the occurrence of types of events. There were no significant differences between groups in proportions of polyps that were completely removed (96% in the Endocut group vs 95% in the forced coagulation group) or the proportion of polyps found to have recurred at surveillance colonoscopy (17% and 17%, respectively). Procedural characteristics were comparable, except that 17% of patients in the Endocut group had immediate bleeding that required an intervention, compared with 11% in the forced coagulation group (P = .006). CONCLUSIONS: In a randomized trial to compare 2 commonly used electrosurgical settings for the resection of large colorectal polyps (Endocut vs forced coagulation), we found no difference in risk of serious adverse events, complete resection rate, or polyp recurrence. Electrosurgical settings can therefore be selected based on endoscopist expertise and preference. Clinicaltrials.gov ID NCT01936948.

RESUMO

Resumo Fogo em campo cirúrgico durante cirurgia palpebral é uma complicação intra-operatória que é dramática tanto para o paciente quanto para a equipe médica. Relatamos um caso de acidente cirúrgico durante cirurgia palpebral onde o paciente sofreu queimadura de supercílio. Houve interação entre o oxigênio usado para sedação (máscara aberta) e uma fonte de ignição representada pelo cautério monopolar. Embora o paciente tenha apresentado boa evolução clínica com recuperação total da lesão cutânea, este caso é um alerta para se evitar tais tipo de ocorrência. Ressaltamos neste trabalho quais as condições implicadas e o modo de prevenção.


Abstract Fire in the surgical field during eyelid surgery is an intra-operative complication that is dramatic for both the patient and the medical staff. It's being reported a case of surgical accident during eyelid surgery where the patient suffered a brow burn. There was interaction between the oxygen used for sedation (open mask) and a source of ignition represented by monopolar cautery. Although the patient presented good clinical evolution with complete recovery of the cutaneous lesion, this case is an alert to avoid such type of occurrence. This work highlights the conditions involved and the way of prevention.

RESUMO

STUDY OBJECTIVE: To demonstrate our technique for hysteroscopic resection of the complete uterine septum. DESIGN: Step-by-step description and demonstration of the procedure using pictures and video (educational video). The video was approved by our hospital's Ethical Committee. SETTING: Uterine malformations represent a rare, yet usually asymptomatic condition that can be associated with poor obstetric outcomes. The European Society for Gynaecological Endoscopy(ESGE)/European Society of Human Reproduction and Embryology (ESHRE)classification is widely accepted for the description of female genital tract anomalies. Treatment of the uterine septum should be considered if fertility is desired, with hysteroscopic resection the gold standard procedure. INTERVENTION: A patient with a U2bC2V1 malformation according to the ESGE/ESHRE classification was treated with hysteroscopy. The procedure was performed in the operating room under general anesthesia using a 9-mm hysteroscope with a bipolar cutting loop. Surgery began with resection of the vaginal septum with monopolar electrosurgery until the cervix was visualized. A Foley probe was placed in 1 uterine hemicavity, and then hysteroscopy on the other hemicavity was performed. Transrectal ultrasound guidance was used to identify the limits of the septum and thereby enhance the safety of the procedure. Resection of the septum started in the upper part until the Foley probe was seen, then continued downward until internal cervical orifice was reached. In the hysteroscopic follow-up after 3 months, we visualized a small residual septum that was resected to fully restore the uterine cavity and improve the patient's obstetric outcomes. The procedure was completed without complications, and a second-look hysteroscopy showed a normal uterine cavity. CONCLUSION: The combination of real-time ultrasound guidance and placement of an intrauterine balloon through the cervix may increase safety during the procedure by providing clear visualization of the uterine cavity and septum border during resection.
