RESUMO

BACKGROUND: HPV is detected in up to 47% of CIN and up to 70% of cervical cancers. It can cause intraepithelial neoplasia, which can eventually progress to invasive carcinoma. Almost all cervical cancers are caused by HPV. Therefore, it is especially important to treat high-risk HPV. For patients who have undergone LEEP surgery, this procedure can effectively treat CIN. However, it has not been studied in a meta-analysis whether HPV remains after the surgery and whether residual HPV increases the recurrence risk of CIN. To address this gap, our study collected all relevant literature to investigate the residual rate of HPV and its potential influence on the recurrence rate of CIN. We aim to provide valuable recommendations for clinicians and patients. METHODS: The Cochrane Library, EMBASE, and PubMed databases were searched from the establishment of the database until October 2023. Stata 12.0 software was used for the statistical analysis. RESULTS: Twelve studies were included, with a total sample size of 1192 cases. The meta-analysis found that the recurrence rate of CIN was quite low [95% CI = 0.5% (0.001, 0.012); P = 0.006] when the margins were negative after LEEP and there was no residual HPV. When HPV was present, the recurrence rate of CIN was significantly higher [95% CI = 18% (0.089, 0.291), P = 0.000], even if the margins were negative. The recurrence rate of CIN with residual HPV was 3.6 times higher than the recurrence rate of CIN without residual HPV. The residual rate of HPV after LEEP with negative margins was 22.7% [95% CI (0.167, 0.294), P = 0.000], which remained relatively high. CONCLUSION: This meta-analysis found that the recurrence rate of CIN without residual HPV and with negative margins after LEEP was quite low, at 0.5%. However, when HPV was residual, the recurrence rate of CIN significantly increased to 18%, even if the margins were negative. The residual rate of HPV was 22.7%, even when the margins were negative after LEEP.

RESUMO

CASE: We present the case of a 54-year-old man who underwent elective hip disarticulation complicated by third-degree burn of the left antecubital fossa requiring skin graft. After careful review, it was determined that "antenna coupling" as a result of electrosurgery was the likely cause. We present an experiment demonstrating this phenomenon. CONCLUSION: Antenna coupling is a real but rare cause of intraoperative burns not previously described in the orthopaedic literature. Care should be taken to avoid coiling or running bovie or other electrosurgical device cords with other metallic cords or corded devices.

RESUMO

BACKGROUND: In polypectomy with mechanical hysteroscopic morcellators, the tissue removal procedure continues until no polyp tissue remains. The decision that the polypoid tissues were removed completely is made based on visual evaluation. In a situation where the polyp tissue was visually completely removed and no doubt that the polyp has been completely removed, short spindle-like tissue fragments on the polyp floor continue in most patients. There are no studies in the literature on whether visual evaluation provides adequate information at the cellular level in many patients in whom polypoid tissues have been determined to be completely removed. The aim of the present study was to analyze the pathological results of the curettage procedure, which was applied following the completion of polyp removal with operative hysteroscopy, and to evaluate whether there was residual polyp tissue in the short spindle-like tissue fragments that the mechanical hysteroscopic morcellator could not remove. The secondary aims of this study were to compare conventional loop resection hysteroscopy with hysteroscopic morcellation for the removal of endometrial polyps in terms of hemoglobin/hematocrit changes, polypectomy time and the amount of medium deficit. METHODS: A total of 70 patients with a single pedunculate polypoid image of 1.5-2 cm, which was primarily visualized by office hysteroscopy, were included in the study. Patients who had undergone hysteroscopic polypectomy were divided into two groups according to the surgical device used: the morcellator group (n = 35, Group M) and the resectoscope group (n = 35, Group R). The histopathological results of hysteroscopic specimens and curettage materials of patients who had undergone curettage at the end of operative hysteroscopy were evaluated. In addition, the postoperative 24th hour Hb/HCT decrease amounts in percentage, the polypectomy time which was measured from the start of morcellation, and deficit differences were compared between groups. RESULTS: In total, 7 patients in the morcellator group had residual polyp tissue detected in the full curettage material. The blood loss was lower in the morcellator group than in the resectoscope group (M, R; (-0.07 ± 0.08), (-0,11 ± 0.06), (p < 0.05), respectively). The deficit value of the morcellator group were higher (M, R; (500 ml), (300 ml), (p < 0.05), respectively). The polypectomy time was shorter in the morcellator group (M, R; mean (2.30 min), (4.6 min), (p < 0.05)). CONCLUSIONS: Even if the lesion is completely visibly removed during hysteroscopic morcellation, extra caution should be taken regarding the possibility of residual tissue. There is a need for new studies investigating the presence of residual polyp tissue.

RESUMO

BACKGROUND: The present study aimed to evaluate the long-term oncological and obstetric outcomes following the loop electrosurgical excision procedure (LEEP) in patients with cervical intraepithelial neoplasia (CIN) and investigate the risk factors for recurrence and preterm birth. METHODS: This retrospective cohort study included patients who underwent LEEP for CIN 2-3 between 2011 and 2019. Demographic information, histopathological findings, postoperative cytology, and human papillomavirus (HPV) status were collected and analyzed. The Cox proportional hazards model and Kaplan-Meier curves with the log-rank test were used for risk factor analysis. RESULTS: A total of 385 patients treated with the LEEP were analyzed. Treatment failure, including recurrence or residual disease following surgery, was observed in 13.5% of the patients. Positive surgical margins and postoperative HPV detection were independent risk factors for CIN1 + recurrence or residual disease (HR 1.948 [95%CI 1.020-3.720], p = 0.043, and HR 6.848 [95%CI 3.652-12.840], p-value < 0.001, respectively). Thirty-one patients subsequently delivered after LEEP, and the duration between LEEP and delivery was significantly associated with preterm-related complications, such as a short cervix, preterm labor, and preterm premature rupture of the membrane (p = 0.009). However, only a history of preterm birth was associated with preterm delivery. CONCLUSIONS: Positive HPV status after LEEP and margin status were identified as independent risk factors for treatment failure in patients with CIN who underwent LEEP. However, combining these two factors did not improve the prediction accuracy for recurrence.

RESUMO

BACKGROUND: This study aimed to compare the efficacy of focused ultrasound (FUS) and the loop electrosurgical excision procedure (LEEP) for the treatment of cervical high-grade squamous intraepithelial lesions (HSILs) among women of reproductive age. METHODS: Case records of patients aged < 40 years who were treated for cervical HSILs using either FUS or LEEP from September 1, 2020 to May 31, 2022 were retrospectively reviewed. Patients were followed up for cure, recurrence, human papillomavirus (HPV) clearance, and complications within 1 year of treatment. Odds ratios and 95% confidence intervals were determined using univariate and multivariate logistic regression models to analyze the association between disease evidence or HPV clearance and treatment modalities or other covariates. RESULTS: Of the 1,054 women who underwent FUS or LEEP, 225 met our selection criteria. Among the selected women, 101 and 124 received FUS and LEEP, respectively. There was no significant difference between the FUS and LEEP groups in the cure rate during the 3-6 months of follow-up (89.11% vs. 94.35%, P = 0.085) and recurrence rate during the 6-12 months follow-up (2.22% vs. 1.71%, P = 0.790). Both groups exhibited enhanced cumulative HPV clearance rates; however, the rates were not significantly different between the FUS and LEEP groups (74.23% vs. 82.79%, P = 0.122 during the 3-6 months follow-up; 84.95% vs. 89.17%, P = 0.359 during the 6-12 months follow-up). Furthermore, the incidence of complications caused by the FUS and LEEP techniques was comparable (5.0% vs. 5.6%, P = 0.818). CONCLUSIONS: We found that FUS and LEEP have similar efficacy, safety, and reliability in treating women (aged < 40 years) with HSILs.

RESUMO

In this paper, we propose a method to model radiofrequency electrosurgery to capture the phenomena at higher temperatures and present the methods for parameter estimation. Experimental data taken from our surgical trials performed on in vivo porcine liver show that a non-Fourier Maxwell-Cattaneo-type model can be suitable for this application when used in combination with an Arrhenius-type model that approximates the energy dissipation in physical and chemical reactions. The resulting model structure has the advantage of higher accuracy than existing ones, while reducing the computation time required.

RESUMO

AIM: To seek the high-risk factors of human papillomavirus (HPV) persistence and residual lesion or recurrence after loop electrosurgical excision procedure (LEEP) focus on the predictive value of intraoperative human papilloma virus (IOP-HPV) testing. METHODS: Intraoperative endocervical sample was obtained with a cytobrush from the remained cervix of 292 patients immediately after LEEP. HPV Genotyping was performed using a polymerase chain reaction technique. All patients followed by HPV genotyping and cytology every 3-6 months. The IOP-HPV testing results and possible risk factors such as age, cytology grade, menopause status, margin involvement, preoperative HPV status, and cervical lesion grade were assessed in predicting persistence of HPV and residual lesion or recurrence after surgery. RESULTS: There were 61 (20.9%) patients presented persistent HPV infection. Multivariate analyses showed that IOP-HPV positive, post-menopause and preoperative HPV multiplex infection was strongly associated with HPV persistence after LEEP, IOP-HPV positive and post-menopause was also associated with residua or recurrent disease after LEEP. CONCLUSIONS: IOP-HPV positive, post-menopause, and preoperative HPV multiplex infection are independent predictors of HPV persistence in patients with cervical squamous intraepithelial lesion treated by LEEP. IOP-HPV test is a new approach that may potentially allow for early identification of patients at high risk of HPV persistence and residua or recurrent disease after LEEP, thereby possibly facilitate an attenuated follow-up schedule for negative patients those at low risk of persistent HPV infection.

RESUMO

OBJECTIVES: Evaluation of the results of treatment of adenocarcinoma in situ by loop electrosurgical excision procedure and the safety of a conservative strategy. METHODS: Identification of all cases of adenocarcinoma in situ treated by loop electrosurgical excision procedure at our institution and follow-up by a conservative strategy. Completeness of the identification of all cases was secured by data from the National Pathology Registry. The treatment strategy was based on cytologic follow-up performed by a general practitioner and, irrespective of margin status of the cone, only the results of the postoperative surveillance were indicative of further treatment. RESULTS: A total of 224 patients were identified. The overall recurrence rate with a mean follow-up time of 87.8 months was 7.6% (17/224). The recurrence rate in patients with involved margins was significantly higher than in patients with uninvolved margins, 15.7% vs 5.2%, respectively. Six recurrences were diagnosed at first examination 6 months postconization in patients with involved margins. They were treated with hysterectomy in 4 cases and reconization in 1 case. If involvement of margins alone had been an indication of further therapy (hysterectomy or reconization) immediately after conization, the conservative management strategy prevented 46 surgical procedures. Two cases of invasive cancer were diagnosed during follow-up, 150 months and 196 months after primary treatment, and after normal follow-up examinations. These 2 cases must be considered de novo cases and cannot be considered treatment failures. CONCLUSION: The conservative management strategy thus seems safe, and unnecessary surgical procedures were avoided.

RESUMO

INTRODUCTION: Hemostasis is an important step in all surgical procedures. Mechanical methods of hemostasis have been gradually abandoned in favor of electrosurgery. The aim of this systematic review was to evaluate the effectiveness of electrosurgical instruments utilized in minimally invasive gynecological procedures. MATERIAL AND METHODS: We performed a systematic review, including randomized controlled trials, prospective and retrospective studies, comparing the outcomes of different energy devices (EDs) used in laparoscopic gynecologic surgeries. We extracted data about blood loss (BL), mean operative time, post-operative pain, hospital stay and complications associated with each electrosurgical device. RESULTS: We included 30 studies reporting comparative outcomes concerning conventional (bipolar and monopolar) and innovative EDs (Harmonic scalpel, LigaSure, Plasma kinetic gyrus, Thunderbeat, EnSeal, Marseal, Caiman and ALAN). New EDs were found to be more efficient in complex surgeries due to less intraoperative BL and shorter operative time. No significant decrease in hospital stay, post-operative pain or complications was found with the use of new energy instruments. CONCLUSIONS: Although new electrosurgical devices seem an appealing and safer option, there is still insufficient evidence for one vessel-sealing technology to be considered superior to another. Therefore, monopolar and conventional bipolar (CB) are still widely used in laparoscopic gynecology.

RESUMO

BACKGROUND: The single-visit strategy, also known as the "screen-and-treat" approach, is widely used to screen for cervical cancer in low- and middle-income countries. The screen-and-treat approach leads to unnecessary or inadequate treatment. Thus, a study was conducted to determine the histopathological patterns of aceto-white lesions on visual inspection with acetic acid (VIA) in patients who underwent a Loop Electrosurgical Excision Procedure (LEEP) at Bugando Medical Centre between January 2016 and December 2020. METHOD: A 5-year retrospective cross-sectional case record review was conducted on 329 women who had LEEP at Bugando Medical Centre following a positive VIA cervical screening test. A standard data abstraction form was used to collect patient information. Missing client information records and LEEP without histopathological results were exclusion criteria. For statistical analysis, STATA version 15 was used; in descriptive statistics, frequency, mean, and standard deviation were used. The Chi2 and Fisher's exact tests were used to investigate the relationship between patient characteristics and histopathological patterns, and a P-value of 0.05 was considered statistically significant in multinomial models. RESULTS: This study looked at 329 patients who had LEEP following a VIA positive but were not eligible for cryotherapy. Our study participants had a mean age of 40 ± 8.2 SD. There were 203 (61.7%) patients with benign lesions, including 4 with schistosomiasis and 2 with cervical tuberculosis. The precancerous lesions were discovered in 100 cases (30.4%), and 26 (7.9%) already had invasive cervical cancer. Out of 100 patients with precancerous lesions, 58 (17.6%) and 42 (12.8%) have high- and low-grade squamous intraepithelial (HSIL and LSIL) lesions, respectively. The presence of a precancerous lesion was found to be associated with age 31-40 years (P-value 0.042) and HIV positivity (P-value 0.004). CONCLUSION: Most patients in this study had benign cervical lesions, which do not require LEEP treatment. Nonetheless, a considerable percentage of invasive cervical malignancies and rare benign diseases such as schistosomiasis and cervical tuberculosis were identified. A screen-and-treat approach within well-equipped tertiary hospitals like Bugando Medical Centre should explore alternative options instead of relying solely on straight LEEP.

RESUMO

BACKGROUND: Human papillomavirus (HPV) infection is the most common sexually transmitted viral infection in humans. AIMS: We evaluated the sexual function of human papillomavirus positive patients after colposcopy and loop electrosurgical excision procedure (LEEP). METHODS: This study enrolled 344 patients with an HPV infection detected on routine screening in 2020-2022. Sexual function was evaluated using the Female Sexual Function Index (FSFI), which consists of six sections: desire, arousal, lubrication, orgasm, satisfaction, and pain. RESULTS: The mean age of the 344 HPV-positive patients was 37.2 ± 8.2 years, and 28.2% of them were unmarried. Colposcopy, cervical biopsy, and LEEP were performed in 251 (73.0%), 189 (54.9%), and 42 (12.2%) patients, respectively. The sexual history and FSFI scores of the patients were recorded. The total and individual parameter scores on the FSFI decreased significantly after colposcopy. Similarly, the total and individual parameter scores on the FSFI were lower at 8 weeks after LEEP compared to those before LEEP. CONCLUSION: Cancer-related fear and anxiety and LEEP may cause sexual dysfunction in HPV-positive patients.

RESUMO

BACKGROUND: Soft tissue sarcomas (STS) constitute a heterogeneous group of rare tumor entities. Treatment relies on challenging patient-tailored surgical resection. Real-time intraoperative lipid profiling of electrosurgical vapors by rapid evaporative ionization mass spectrometry (REIMS) may aid in achieving successful surgical R0 resection (i.e., microscopically negative-tumor margin resection). Here, we evaluate the ex vivo accuracy of REIMS to discriminate and identify various STS from normal surrounding tissue. METHODS: Twenty-seven patients undergoing surgery for STS at Maastricht University Medical Center+ were included in the study. Samples of resected STS specimens were collected and analyzed ex vivo using REIMS. Electrosurgical cauterization of tumor and surrounding was generated successively in both cut and coagulation modes. Resected specimens were subsequently processed for gold standard histopathological review. Multivariate statistical analysis (principal component analysis-linear discriminant analysis) and leave-one patient-out cross-validation were employed to compare the classifications predicted by REIMS lipid profiles to the pathology classifications. Electrosurgical vapors produced during sarcoma resection were analyzed in vivo using REIMS. RESULTS: In total, 1200 histopathologically-validated ex vivo REIMS lipid profiles were generated from 27 patients. Ex vivo REIMS lipid profiles classified STS and normal tissues with 95.5% accuracy. STS, adipose and muscle tissues were classified with 98.3% accuracy. Well-differentiated liposarcomas and adipose tissues could not be discriminated based on their respective lipid profiles. Distinction of leiomyosarcomas from other STS could be achieved with 96.6% accuracy. In vivo REIMS analyses generated intense mass spectrometric signals. CONCLUSION: Lipid profiling by REIMS is able to discriminate and identify STS with high accuracy and therefore constitutes a potential asset to improve surgical resection of STS in the future.

RESUMO

PURPOSE: To compare conventional bipolar electrosurgery with advanced bipolar vessel sealing (ABVS) devices for total laparoscopic hysterectomy (TLH). METHODS: A systematic review was conducted by searching Scopus, PubMed/MEDLINE, ScienceDirect, and Cochrane Library from January 1989 to November 2021. We identified all studies comparing ABVS devices with conventional bipolar electrosurgery in TLH and reporting at least one of the following outcomes: total blood loss, total operative time, hospital stay, perioperative complications, or costs. Meta-analysis was conducted with a random effect model reporting pooled mean differences and odds ratios (ORs) with related 95% confidence intervals (CIs). RESULTS: Two randomized controlled trials and two retrospective studies encompassing 314 patients were included out of 615 manuscripts. The pooled estimated total blood loss in the ABVS devices group was lower than conventional bipolar electrosurgery of 39 mL (95% CI - 65.8 to - 12.6 mL; p = .004). The use of ABVS devices significantly reduced the total operative time by 8 min (95% CI - 16.7 to - 0.8 min; p = .033). Hospital stay length did not differ between the two groups, and a comparable overall surgical complication rate was observed [OR of 0.9 (95% CI 0.256 - 3.200; p = .878]. CONCLUSIONS: High-quality evidence comparing ABVS devices with conventional bipolar electrosurgery for TLH is lacking. ABVS devices were associated with reduced total blood loss and operative time; however, observed differences seem clinically irrelevant. Further research is required to clarify the advantages of ABVS devices over conventional bipolar electrosurgery and to identify cases that may benefit more from their use.

RESUMO

INTRODUCTION: Early management of high-grade cervical intraepithelial neoplasia is one of the key steps in cervical cancer prevention after vaccination and screening. It relies on lesion removal by surgical excision, and the French National Cancer Institute (INCa) in 2016 recommend using a loop electro excision procedure (LEEP). However, the laser excision method seems to be as effective with similar rates of negative excision margins and postoperative clearance of HPV. OBJECTIVE: The main objective of our study was to compare the laser excision method to LEEP by evaluating the quality of the surgical margins. We also studied factors associated with the status of the margins and the depth of cones. METHODS: We conducted a retrospective unicentric study between 2009 and 2017. RESULTS: Two hundred and thirty-one patients were included: 154 laser excisions and 77 LEEP. Negative surgical margin was achieved in 69.5 % of laser excisions and 72.7 % of LEEP (p = 0.649). Concerning factors predicting margin status, only a greater cone depth was associated with negative margins (OR: 0.91 (95 %CI: 0.84, 0.89); p = 0.02). The surgical technique was not found to be associated with the status of the margins (OR: 0.85 (95 %CI: 0.46,1.56); p = 0.61). Concerning factors predicting cone depth, only the LEEP was associated with a shorter cone depth (OR: 0.24 (95 %CI: 0.08, 0.69); p 0.008). Significant results are based on univariate analysis. CONCLUSION: No difference was found between the two technics concerning the rate of negative margins. However, LEEP seems to be associated with shorter cone depth in this study.

RESUMO

BACKGROUND: Several well-trained expert instructors who completed the "Train-The-Trainer (TTT)" course are required to disseminate the safe use of surgical energy devices, which can be learned through the Fundamental Use of Surgical Energy (FUSE) program. This study aimed to explore whether the hybrid FUSE TTT course is feasible and effective, which can improve teaching skills of surgical energy. METHODS: The hybrid TTT course, which was designed to train FUSE-certified personnel as instructors, comprised three virtual sessions spread over 5 h in total and a 1-day in-person training, followed by a 100-min FUSE electrosurgery hands-on workshop in practice as an instructor. The participants reported on self-confidence regarding knowledge of various energy devices or adverse events before, immediately after, and 6 months after the course. Participants and experienced FUSE instructors assessed the trainees' presentation skills at the beginning of the in-person training and after the hands-on workshop. The primary outcomes were the feasibility and completion rate of the entire course. RESULTS: Seventeen participants completed the entire couse; most (94%) were satisfied with the course. Self-confidence in knowledge about various contents improved significantly: the fundamentals of electrosurgery (post, p < 0.001; 6 months, p = 0.01), mechanism and prevention of adverse events (post, p = 0.001; 6 months, p = 0.04), monopolar instruments (post, p = 0.002; 6 months, p = 0.01), bipolar instruments (post, p = 0.01; 6 months, p = 0.06), and integration with other medical devices (post, p = 0.006; 6 months, p = 0.02). The presentation skill index scores of self- and peer assessments improved after the in-person training (self-assessment [pre 44 vs. post 56, p < 0.001], peer assessment [pre 39 vs. post 68, p < 0.001]). CONCLUSIONS: The hybrid TTT course can provide FUSE-certified personnel with an improved self-confidence concerning knowledge of surgical energy and improve their presentation skills with midterm retention. This can help build trainees' self-confidence as instructors.

RESUMO

OBJECTIVE: Comprehensively assess the prevalence of monopolar electrosurgery-related device complications among cochlear implant (CI) recipients. STUDY DESIGN: Multifaceted retrospective review and survey. SETTING: Tertiary medical center. METHODS: Multifaceted approach including: (i) review of the current literature; (ii) historical review of institutional data from an academic, tertiary CI center; (iii) review of industry data provided by 3 Food and Drug Administration-approved CI manufacturers; and (iv) survey of high-volume CI centers. RESULTS: Literature review identified 9 human studies, detailing 84 devices with 199 episodes of device-cautery exposure. From studies reporting on patients records, no implant showed evidence of damage after exposure. One cadaveric study using dental cautery reported 1 episode of device damage. Review of institutional records did not identify any CI damage in 84 instances of exposure. Data from the 3 major implant manufacturers showed a single report of damage that could be reasonably linked to monopolar electrosurgery, out of a possible 689,426 CIs. Last, a survey of 8 high-volume CI centers did not identify any adverse events associated with monopolar cautery. CONCLUSION: These data estimate the risk of adverse device-related events or tissue injury to be extraordinarily low. Short of operating in immediate proximity to the CI (ie, the ipsilateral temporoparietal scalp), these data indicate that monopolar electrosurgery can be used in the body and the head-and-neck of CI recipients with nominal risk. These findings may guide decision-making in cases that are optimally or preferably performed with monopolar electrocautery and can be used to counsel CI patients following inadvertent exposures.
