RESUMO

BACKGROUND: The purpose of this study was to predict the risk factors for residual lesions in patients with high-grade cervical intraepithelial neoplasia who underwent total hysterectomy. METHODS: This retrospective study included 212 patients with histologically confirmed high-grade cervical intraepithelial neoplasia (CIN2-3) who underwent hysterectomy within 6 months after loop electrosurgical excision procedure (LEEP). Clinical data (e.g., age, menopausal status, HPV type, and Liquid-based cytology test(LCT) type), as well as pathological data affiliated with endocervical curettage (ECC), colposcopy, LEEP and hysterectomy, were retrieved from medical records. A logistic regression model was applied to estimate the relationship between the variables and risk of residual lesions after hysterectomy. RESULTS: Overall, 75 (35.4%) patients had residual lesions after hysterectomy. Univariate analyses revealed that positive margin (p = 0.003), glandular involvement (p = 0.017), positive ECC (p < 0.01), HPV16/18 infection (p = 0.032) and vaginal intraepithelial neoplasia (VaIN) I-III (p = 0.014) were factors related to the presence of residual lesions after hysterectomy. Conversely, postmenopausal status, age ≥ 50 years, ≤ 30 days from LEEP to hysterectomy, and LCT type were not risk factors for residual lesions. A positive margin (p = 0.025) and positive ECC (HSIL) (p < 0.001) were identified as independent risk factors for residual lesions in multivariate analysis. CONCLUSIONS: Our study revealed that positive incisal margins and ECC (≥ CIN2) were risk factors for residual lesions, while glandular involvement and VaIN were protective factors. In later clinical work, colposcopic pathology revealed that glandular involvement was associated with a reduced risk of residual uterine lesions. 60% of the patients with residual uterine lesions were menopausal patients, and all patients with carcinoma in situ in this study were menopausal patients. Therefore, total hysterectomy may be a better choice for treating CIN in menopausal patients with positive margins and positive ECC.

RESUMO

Electrosurgery has emerged as a groundbreaking tool in the field of structural cardiac interventions, revolutionizing the approach to complex cardiac conditions. This review delves into the core principles, procedural techniques, outcomes, and potential challenges associated with various electrosurgical procedures within the realm of structural cardiology. Five key electrosurgical procedures performed in complex structural interventions are highlighted in this review. They are the Transcaval Access, BASILICA, LAMPOON, ELASTIC/ELASTA-Clip, and SESAME procedures. While these electrosurgery procedures hold promise and have demonstrated positive outcomes, their technical intricacies, patient selection criteria, and the need for further research remain important considerations. As technology continues to evolve and more data becomes available, electrosurgery is poised to continue shaping the landscape of cardiac care, offering minimally invasive alternatives, and improving patient outcomes in complex structural cardiac interventions.

RESUMO

PURPOSE: Congenital distichiasis is managed either by ablation, using laser, cryotherapy, or electroepilation, or by surgical excision with mucous membrane grafting. Ablative procedures are usually blind as the exact depth of distichiatic eyelashes is unknown. The described surgical technique utilizes meibography for imaging the root and depth of distichiatic eyelashes that aided in performing electroepilation. METHODS: Six patients (n = 24 eyelids; mean age 15.5 ± 12.2 years) underwent infrared meibography (Oculus Keratograph 5 M) and noninvasive tear breakup time prospectively. Eyelashes were electroepilated using a premarked needle inserted at a depth based on meibography findings in 4 patients. Surgical success was defined as no distichiatic eyelash regrowth and functional success was defined as the resolution of symptoms at a minimum of 3 months of follow-up. RESULTS: All 6 patients had all 4 eyelids involved to varying degrees, with a total of 230 distichiatic eyelashes. The median number of distichiatic eyelashes was 9 in the upper eyelids and 4.5 in the lower eyelids. Meibography revealed visible distichiatic eyelash roots in 70% of eyelashes in the upper eyelid and 87.8% in the lower eyelid, respectively. The median eyelash root depth was 2.7 mm (mean 2.9 mm, range 1.8-5.4 mm). The mean noninvasive tear breakup time was 12.2 seconds despite absent or rudimentary meibomian gland segments seen on meibography. The anatomical success was 75% (12/16 eyelids), and functional success was 87.5% (7/8 eyes) at a median follow-up of 5.5 months. CONCLUSION: Preoperative infrared meibography in eyelids with congenital distichiasis helps estimate the eyelash depth and can be used to guide eyelash ablation procedures.

RESUMO

BACKGROUND: The prevention of cervical cancer can be achieved by treating high-grade cervical precancerous lesions. Treatment options for cervical precancer include excisional procedures, and ablation treatments. Despite the long pre-invasive course of the disease, literature addressing sexual function post-treatment for cervical pre-invasive lesions is scarce. This study aims to bridge this gap and assess the sexual function and the acceptability, efficacy, safety, and complications of loop electrosurgical excision procedure (LEEP) versus thermal ablation. METHODS: The prospective open-label randomized controlled trial recruited women aged 22-55 with histologically confirmed Cervical Intraepithelial Neoplasia (CIN) 2 and 3 lesions. Participants were randomly allocated to either thermal ablation or LEEP. All cases were followed up with a Pap smear at three- and six-months post treatment. Sexual health assessments were conducted using a questionnaire at baseline and 3 months post-procedure. Secondary outcome measures included comparison of acceptability, pain, and side effects between the two treatment measures. RESULTS: Out of 1356 screened cases, 60 were included in the study and randomized in two groups. The groups had similar baseline characteristics. Duration of LEEP was longer than thermal ablation (25.33 vs. 20.67 minutes), with higher pain reported 10 minutes post-procedure in the LEEP group. Three months post-procedure, both groups showed comparable acceptability and symptom relief. Sexual function parameters significantly improved in the thermal ablation group compared to LEEP, including satisfaction, desire, lubrication, flexibility, and ability to reach climax. CONCLUSION: LEEP and thermal ablation are effective treatments for CIN with similar efficacy at 6 months. Thermal ablation demonstrated advantages in procedure time and post-procedural pain but exhibited varying effects on sexual function, improving satisfaction and desire. In contrast, LEEP showed a decrease in satisfaction and potential alterations in lubrication and flexibility. Larger-sample, longer-term studies are recommended for further insights.

RESUMO

OBJECTIVES: To investigate the relationship between preoperative inflammatory markers and recurrence of CIN after loop electrosurgical excision procedure (LEEP). METHODS: A retrospective historical cohort study was conducted at gynecologic oncology unit, Bhumibol Adulyadej Hospital, Royal Thai Air Force, Thailand. Data was collected from medical records of CIN cases from year 2016 to 2021. Inclusion criteria were subjects who were diagnosed of CIN and underwent LEEP with pathologic confirmation and followed up for two years (at 6 months, 1 year, and 2 years). Preoperative complete blood count (CBC) was obtained within one month for calculation as systemic inflammatory values. RESULTS: One hundred and ten cases of CIN were enrolled. Mean age of participants was 48.1 years old. Three-fourths (83/110) of the participants had histological confirmation as CIN2/3. Sixteen (18/110) and twenty (22/110) percentage of cases had recurrence of disease at 1 and 2 years, respectively. Monocytes /lymphocytes ratio (MLR) and systemic inflammation response index (SIRI) could predict recurrence of CIN within 2 years. MLR more than 0.16 and SIRI more than 0.57 gave the sensitivity and negative predictive value (NPV) at percentage of 77.3/ 81.8 and 91.8/ 90.2, respectively. Combination of MLR and SIRI had sensitivity and NPV at 90.5 and 95.4 percent, respectively. MLR and SIRI could not predict marginal involvement, glandular involvement, and LEEP confirmed CIN 2/3. CONCLUSION: Pretreatment MLR and SIRI were statistically significant in predicting the recurrence in CIN after post LEEP procedure within 2 years follow up.

RESUMO

The BiZact device, a bipolar electrosurgical scissor designed for tonsillectomy, minimizes thermal tissue damage and seals blood vessels <3 mm in diameter while dividing the soft tissue. This study describes the authors' experience with sinonasal tumor surgery using a BiZact and discusses its clinical utility and advantages. The authors analyzed BiZact-assisted endoscopic sinonasal tumor surgery cases between January 2021 and May 2023. Data were collected on patients' demographics, histopathology, extent of tumor involvement, surgical records, and postoperative medical records. Clinical utility was assessed using the success rate of complete tumor excision, estimated blood loss during surgery, device-related complications, and operation time. A survey of the surgeons' BiZact experience was also conducted. The diagnoses of the 20 patients in this study included squamous cell carcinoma (n = 2), malignant melanoma (n = 1), sarcoma (n = 1), natural killer cell lymphoma (n = 1), inverted papilloma (n = 12), angiofibroma (n = 2), and schwannoma (n = 1). This pilot study demonstrated a shortened operative time, with a median of 0.8 hours and <100 mL of intraoperative blood loss. In addition, no BiZact-related complications were observed. The BiZact device allows efficient sinonasal surgery because it has the unique advantage of one-step sealing and cutting. BiZact-assisted endoscopic sinonasal tumor surgery is a beneficial and safe procedure that reduces blood loss during surgery, shortens the operative time, and minimizes postoperative complications.

RESUMO

BACKGROUND: Both the traditional loop electrosurgical excision procedure (LEEP) and the newly developed 5-aminolevulinic acid photodynamic therapy (ALA-PDT) are used to treat high-grade squamous intraepithelial lesions. However, the clinical efficacy and safety of these two therapies have rarely been compared. Thus, this study aimed to compare the clinical efficacy and safety of the two treatment regimens. METHODS: One hundred and twenty patients in two groups (60 + 60) with grade 2 cervical intraepithelial neoplasia (CIN2) were voluntary treated with photodynamic therapy or LEEP between June 2020 and December 2022. Follow-up was conducted at 3, 4-6, and 7-12 months after treatment. RESULTS: Although the total effective rate of LEEP was higher during the first 6 months after treatment, both the total effective rate of lesion degradation and the double-negative rate of high-risk HPV16/18 and liquid-based cervical cytology by ALA-PDT treatment increased with time and finally exceeded those of LEEP at 7-12 months. CONCLUSIONS: ALA-PDT may be more promising than LEEP for treating patients with CIN2 because of the better CIN2 degradation and high-risk HPV negativity, less damage, and greater fertility conservation, especially after 6 months.

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: 5-Aminolevulinic acid-mediated photodynamic therapy (5-ALA-PDT) is a possible minimally-invasive treatment for high-grade cervical intraepithelial neoplasia (HSIL). The present study was carried out to assess the effect of 5-ALA-PDT and loop electrosurgical excision procedure (LEEP) in cervical squamous intraepithelial neoplasia (CIN2) combined with high-risk human papillomavirus (HR-HPV) infection. METHODS: In this study, 190 patients with CIN2 and HR-HPV infection were finally included. They were divided into the LEEP Group (n = 116) and PDT Group (n = 74) according to gynecologist's recommendation and patient's willingness. All patients were followed up at 4-6 months and 12 months after treatment, including HPV testing, cytology, and colposcopy examination. RESULTS: (1) 4-6 months after treatment, the pathological regression rate was 97.30 % (72/74) in the PDT group and 98.28 % (114/116) in the LEEP group (P = 0.952). The HPV clearance rate was 81.08 % (60/74) in the PDT group and 80.17 % (93/116)in the LEEP group (P = 0.877). (2) 12 months after treatment, the pathological regression rate was 93.24 % (69/74) in the PDT group and 96.55 % (112/116) in the LEEP group (P = 0.486). The recurrence rate of CIN2 was 4.05 % (3/74) in the PDT group and 1.72 % (2/116) in the LEEP group (P = 0.608). The HPV clearance rate was 90.54 % (67/74) in the PDT group and 89.66 % (104/116)in the LEEP group (P = 0.843). The reinfection rate of HR-HPV was 5.41 % (4/74) in the PDT group and 1.72 % (2/116) in the LEEP group (P = 0.322). (3) The adverse reactions in the PDT Group were slightly lower than that in the LEEP Group (P = 0.4956), but the incidence of vaginal bleeding in the PDT group was lower than that in the LEEP group during follow-up. CONCLUSIONS: The effectiveness of 5-ALA-PDT is similar to LEEP for CIN2 with less side effects. Therefore, 5-ALA-PDT, a non-invasive treatment, may be an effective method for CIN2 patients of childbearing age.

RESUMO

OBJECTIVE: This study evaluated the efficacy of the Minimally Invasive Targeted Resection (MiTR) device, a novel electrosurgical instrument that allows for targeted excision of a lung abnormality while using bipolar radiofrequency (RF) energy to seal blood vessels and airways. METHODS: The MiTR system was evaluated in 7 acute and 2 chronic porcine (7-day) models to evaluate the efficacy of tissue excision with bipolar RF sealing of blood vessels and airways and application of an autologous blood patch into the excised tissue cavity. Air leak was recorded for all evaluations. The study was approved by the institutional ethical board. RESULTS: Nineteen lung tissue samples, measuring 2.5 cm long × 1.2 cm diameter, were excised. In 8 of 9 animals (89%), hemostasis and pneumostasis were observed visually at the completion of the procedure. In 2 of 2 chronic animals (100%), hemostasis and pneumostasis persisted for the 7-day observation period. Histologic examination of the excised samples showed preservation of the core parenchymal architecture without evident tissue damage of the samples that would impair pathologic analysis. CONCLUSIONS: Percutaneous resection of targeted lung tissue with the MiTR system demonstrated hemostasis and pneumostasis while obtaining a histologically intact sample. After regulatory approval, the use of this device could offer more tissue for analysis than a transthoracic needle biopsy or bronchoscopy and a far less invasive alternative to video-assisted thoracic surgery or thoracotomy. This may also expand patient and physician options for the early diagnosis and treatment of lung cancer.

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: 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

OBJECTIVE: Detecting the cancerous growth margin and achieving a negative margin is one of the challenges that surgeons face during cancer procedures. A smart electrosurgical knife with integrated optical fibers has been designed previously to enable real-time use of diffuse reflectance spectroscopy for intraoperative margin assessment. In this paper, the thermal effect of the electrosurgical knife on tissue sensing is investigated. METHODS: Porcine tissues and phantoms were used to investigate the performance of the smart electrosurgical knife after electrosurgery. The fat-to-water content ratio (F/W-ratio) served as the discriminative parameter for distinguishing tissues and tissue mimicking phantoms with varying fat content. The F/W-ratio of tissues and phantoms was measured with the smart electrosurgical knife before and after 14 minutes of electrosurgery. Additionally, a layered porcine tissue and phantom were sliced and measured from top to bottom with the smart electrosurgical knife. RESULTS: Mapping the thermal activity of the electrosurgical knife's electrode during animal tissue electrosurgery revealed temperatures exceeding 400 °C. Electrosurgery for 14 minutes had no impact on the device's accurate detection of the F/W-ratio. The smart electrosurgical knife enables real-time tissue detection and predicts the fat content of the next layer from 4 mm ahead. CONCLUSION: The design of the smart electrosurgical knife outlined in this paper demonstrates its potential utility for tissue detection during electrosurgery. SIGNIFICANCE: In the future, the smart electrosurgical knife could be a valuable intraoperative margin assessment tool, aiding surgeons in detecting tumor borders and achieving negative margins.

RESUMO

BACKGROUND: Surgeons use electrosurgery daily, though most of them are unfamiliar with its basic safety principles. METHOD: We have designed a hands-on simulation session to teach OBGYN trainees principles of electrosurgery with practical implications for safety in the operating room. 15 participants completed post-session surveys. EXPERIENCE: Our experience of serially refining teaching materials and electrosurgery demonstrations resulted in a comprehensive guide to electrosurgery in OBGYN. CONCLUSION: This report will allow surgeon educators to implement simulation training in their institutions.

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: 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

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.
