Efficacy and safety of blue laser en bloc enucleation in the treatment of non-muscle invasive bladder cancer: report of 50 cases from a single center / 现代泌尿外科杂志

【Objective】 To compare the efficacy and safety of blue laser en bloc enucleation and traditional plasmakinetic electrocautery in the treatment of non-muscle invasive bladder cancer (NMIBC). 【Methods】 A total of 50 NMIBC patients treated in our hospital during Oct.2018 and Dec.2019 were enrolled. A randomized, incomplete blinding, parallel control design and non-inferior test method was adopted. The control group (electrocautery group) used plasmakinetic electrocautery for transurethral resection, and the experimental group (blue laser group) used semiconductor blue laser for transurethral en bloc enucleation. The effective resection rate, operation time, postoperative catheter indwelling time, length of hospital stay, perioperative hemoglobin changes and obturator nerve reflex were compared. 【Results】 There were 24 patients in the blue laser group and 26 in the electrocautery group. The effective dissection rate and hemostasis rate in both groups reached 100%. The blue laser group had slightly longer operation time than the electrocautery group (55 min vs.42 min, P=0.009), but lesser hemoglobin decrease (5.7 g/L vs. 10.4 g/L, P=0.007). There were no significant differences in urinary catheter indwelling time, length of hospital stay and reoperation rate between the two groups. The electrocautery group had 3 cases of obturator nerve reflex, while the blue laser group had none. 【Conclusion】 Compared with the traditional electrocautery, blue laser has good vaporization cutting and coagulation hemostatic effects on bladder tumor tissue, and can completely enucleate tumors in a front-firing model with less bleeding and no obturator nerve reflex, which can be used as a new, efficient, safe and easy-to-learn method for NMIBC surgery. However, its effects on postoperative recurrence rate and progression rate still need further studies.

Comparison of postoperative morbidity between conventional cold dissection and bipolar electrocautery tonsillectomy: which technique is better? / Comparação da morbidade pós-operatória entre tonsilectomia por dissecção a friotradicional e por eletrocautério bipolar: qual técnica é a melhor?

Abstract Introduction Tonsillectomy is one of the most common surgeries in the head and neck worldwide. This operation is carried out by different methods, the most frequent of which are the cold dissection and bipolar electrocautery techniques. Objective This study was conducted to assess and compare postoperative morbidity between cold dissection and bipolar electrocautery. Methods This prospective randomized clinical trial was performed on 534 patients who underwent tonsillectomy in Vali-e-Asr Hospital of Birjand, east of Iran from October, 2013 to October, 2015. The patients were systematically selected for cold dissection technique or bipolar electrocautery technique groups. Time of surgery, amount of intraoperative blood loss, postoperative hemorrhage, the intensity of local pain 4 and 24 hours after operation and nausea and/or vomiting were recorded and compared in the two groups to decide which technique is better. The data were analyzed in SPSS software (ver-22). The p-value less than 0.5 was considered significant. Results In this study, 51.7% of the cold dissection technique patients and 50.6% of the bipolar electrocautery technique participants were male. Compared to the cold dissection technique, the average intraoperative blood loss was significantly lower (p < 0.001) in the bipolar electrocautery technique group, while the intensity of local pain 4 and 24 hours after the operation was significantly higher (p < 0.001). Other variables showed no significant differences between the two groups. Conclusion Based on the findings of the present investigation, the bipolar electrocautery technique is suggested for tonsillectomy in children, while the cold dissection technique is preferred for adult patients.

Resumo Introdução A tonsilectomia é uma das cirurgias mais comuns de cabeça e pescoço em todo o mundo. Essa cirurgia é feita por diferentes métodos, os mais frequentes são a dissecção a frio e por eletrocauterização bipolar. Objetivo Este estudo foi feito para avaliar e comparar a morbidade pós-operatória na dissecção a frio e eletrocauterização bipolar. Método Este ensaio clínico prospectivo e randomizado foi feito em 534 pacientes submetidos a tonsilectomia no Vali-e-Asr Hospital de Birjand, no leste do Irã, de outubro de 2013 a outubro de 2015. Os pacientes foram selecionados de forma sistemática para o grupo submetido à técnica de dissecção a frio ou para o grupo com uso da técnica de eletrocauterização bipolar. Para a avaliação acerca da melhor técnica, os seguintes parâmetros foram registrados e comparados entre os dois grupos: tempo de cirurgia, quantidade de perda sanguínea intraoperatória, hemorragia pós-operatória, intensidade da dor local 4 e 24 horas após a cirurgia e ocorrência de náuseas e/ou vômitos. Os dados foram analisados no software SPSS (versão 22). O valor de p inferior a 0,5 foi considerado significante. Resultados Neste estudo, 51,7% dos participantes do grupo técnica de dissecção a frio e 50,6% do grupo técnica de eletrocauterização bipolar eram do sexo masculino. No grupo operado pela técnica de eletrocauterização bipolar a média de perda sanguínea intraoperatória foi significantemente menor (p < 0,001) em comparação à técnica de dissecção a frio, enquanto a intensidade da dor local 4 e 24 horas após a cirurgia foi significativamente maior (p < 0,001). As outras variáveis não apresentaram diferenças significantes entre os dois grupos. Conclusão Com base nos achados da presente investigação, para a tonsilectomia em crianças sugere-se o uso da técnica de eletrocauterização bipolar, enquanto a técnica de dissecção a frio é recomendada para pacientes adultos.

Spinal Accessory Dysfunction Following Neck Dissection with Harmonic Scalpel V/S Electrocautery – A Single Centre Experience

Aims:This study is an effort towards comparing the efficacy of the Harmonic Focus and Electrosurgical technique with regard to nerve injury especially spinal accessory nerve and its morbidity postoperatively after neck dissection.Sample:Ninety patients of oral carcinoma who required neck dissection were included in the study.Study Design:This is a prospective study.Place and Duration of Study:Bhagwan Mahaveer Cancer Hospital & Research Centre, Jaipur, Rajasthan, India for a period of 17 months from November 2016 to March 2018.Methodology:Patients’ post-operative recovery was studied prospectively by using parameters pertaining to shoulder function and shoulder pain.Results:There were significant differences in the pain and abduction deformity at various time periods after surgery. However differences in the quality of life did not show significant difference at the end of 3 months. For up to one month pain scores were lower for Harmonic Focus and shoulder function was better through 3 months.Conclusion:Though the technique of neck dissection (harmonic v/s electro cautery) has significant impact on shoulder dysfunction, despite that in postoperative period shoulder function measured by way of shoulder pain and shoulder abduction recover almost fully during follow-up period without causing significant morbidity and with minimal effect on quality of life. There are few recommendations we would like to suggest that if incorporated, they might significantly affect the outcome and better results.

Comparison Of Superficial Surgical Site Infections Following Use Of Diathermy And Scalpel For Making Skin Incisions In Open Inguinal Hernia Repair

The use of electrocautery for making skin incisions remains controversial. Its effect on the rate of Superficial Surgical Site Infection (SSSI) vis-à-vis scalpel use was compared in this study. Atotal of 100 patients undergoing open inguinal hernia repair were divided into two: 50 in Electrocautery group, 50 in Scalpel group. Patients were assessed for up to 30 days post-operatively by an assessor blinded to the method used for making skin incision. CDC/NHSN criterion for SSSI was adopted for wound assessment while grading was done using Southampton Wound Grading System. Both groups had comparable mean age (p-value=0.29) and BMI (p-value=0.39). The difference in the incidence of SSSI (5 in Electrocautery, 7 in Scalpel group) on statistical analysis was found to not be significant (p-value=0.53). We conclude that skin incision made with electrocautery is a safe alternative and a convenient method for performing surgeries.

Relatamos dois casos de queimaduras relacionadas ao uso do bisturi elétrico e promovemos uma revisão de literatura, pois o conhecimento dos fundamentos da eletrocirurgia, seu uso correto, a escolha de um equipamento seguro, o monitoramento constante e a investigação imediata diante de quaisquer suspeitas com certeza podem melhorar a experiência operacional para ambos, cirurgião e paciente.

Two Cases of Corneal Neovascularization Improved by Electrocauterization and Subconjunctival Bevacizumab Injection

PURPOSE: To report an experience of improving symptoms through treatment with electrocauterization and subconjunctival bevacizumab injection in two patients with keratitis accompanied by corneal neovascularization and opacity. CASE SUMMARY: (Case 1) A 20-year-old woman visited our institution complaining of binocular blurred vision and congestion for the previous 3 years. Her best corrected visual acuity (BCVA) was 0.07 in the right eye and 0.4 in the left eye (Han Chun-suk visual acuity chart, decimal). The diagnosis was bilateral rosacea keratitis. Antibiotics, steroid eye drops and oral antibiotics were administered, but no improvement was observed. Electrocauterization was performed at the origin of the neovascularization of the cornea and bevacizumab was injected at the peripheral subconjunctiva in the right eye. Thereafter the corneal neovascularization did not recur, corneal opacity was reduced, and BCVA improved to 0.5. (Case 2) A 19-year-old woman visited complaining of left eye congestion for the previous 3 years. Her BCVA was 1.0 in the right eye and 0.08 in the left eye.The diagnosis was phlyctenular keratitis of the left eye. Antibiotics, steroid eye drops and oral antibiotics were administered, but no improvement was observed. Therefore, electrocauterization and subconjunctival bevacizumab injection were performed in the cornea of the left eye, after which corneal neovascularization and opacity decreased. CONCLUSIONS: In these cases, we report improvement of symptoms after treatment with electrocauterization and subconjunctival bevacizumab injection after failed treatment of palpebral sanitation, antibiotic and steroid.

Objective: to prove that exposure to smoke resulting from electrocoagulation causes changes in the nasal mucosa of physicians in training at a public hospital in Mexico. Methodology: a prospective fixed cohort study was conducted with a working universe consisting of 43 physicians distributed as follows: a group of 20 professionals with non-surgical specialties (thus unexposed to electrocautery smoke inhalation), and another group of 23 with surgical specialties (thus they were exposed to electrocautery smoke inhalation). They underwent two nasal biopsies: one at the beginning of the study and another after training as specialists for four years. The biopsies were reviewed by the hospital´s chief of Pathology and the incidence of changes in the nasal mucosa in both groups was calculated together with exposure index and the relative risk. Results: the biopsies performed at baseline showed that none of the specialists in training included in this study had damages in the nasal mucosa. The final biopsies, performed after the four-year medical training, had the following results: 70% of the medical residents, who were exposed, showed some histopathological changes in the nasal mucosa (hyperplasia or squamous metaplasia), whereas only 5% (1/20) of the unexposed individuals had them; the risk factor for nasal mucosa damage by exposure was estimated at 13.8. The most common lesions resulting from exposure to smoke from electrocoagulation were hyperplasia and squamous metaplasia. Conclusions: our results demonstrate that residents exposed to smoke produced by electrocoagulation have changes in the nasal mucosa.

Surgical Techniques for the Treatment of Tongue Tie in Children: A Comparative Study.

Introduction: Ankyloglossia is another name for tongue tie which in mild form is characterized by mucous membrane bands to complete ankyloglossia whereby the tongue is tethered to the floor of the mouth. It can affect feeding, speech, and oral hygiene [3] as well as have mechanical/social effects. Ankyloglossia can also prevent the tongue from contacting the anterior palate. Materials and Methods: The study aimed to find out best possible surgical modality of frenectomy by comparing scalpel, electro-cautery and CO2 laser in the treatment of tongue tie. This is a prospective randomized double blind clinical trial conducted in the department of ENT, Dr. Shankarrao Chavan Government Medical College, Nanded, Maharashtra. All patients were categorized in to three groups randomly as group A, group B and group C. Each group contains 18 patients and among group A, B and C, frenectomy was done by conventional scalpel technique, by bipolar cautery and CO2 laser respectively. Then patients were assessed on post-operation day 1 for symptomatology and inflammatory signs, on post-operation day 7 for wound healing and any complications and also after 1 month post-operation for scar and contracture of wound. Results: In our study, about 61% of population is of male and female were remaining 39% (ratio 1.6:1) which is matching with the previous studies. Amongst all patients most common age group is between 1-4 years of age group. Most of the patients were in Kotlow’s class III having severe ankyloglossia (3‑7 mm) followed by class i having Mild ankyloglossia (12‑16 mm). Conclusion: Laser and electro-cautery treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique.

Comparison between Laser, Electrocautery and Scalpel in the Treatment of Drug-Induced Gingival Overgrowth: A Case Report.

Drug-induced gingival overgrowth (DIGO) is a well-recognized, unwanted side-effect associated with three major drug groups - anticonvulsants, immunosuppressants and the calcium channel blockers. The prevalence of this unwanted side effect is 25-80% and is also dependent on other factors such as type of drug, dosage, duration of treatment, genetic predisposition, and patient’s oral hygiene maintenance. Three different treatment modalities viz., scalpel, laser, and electrocautery can be used for treating DIGO. Each method carries its own merits and demerits. In the present case report, these three different treatment modalities are used in the same patient in order to compare their handling properties and effect on initial wound healing. Though scalpel remains to be gold standard treatment, use of laser finds some more advantages over the electrocautery for treatment of DIGO.

Ultrasonic scalpel versus electrocautery in axillary dissection in breast cancer patients / 临床外科杂志

Objective To evaluate the effects of ultrasonic scalpel and traditional electrocautery on postoperative complications in axillary dissection for breast cancer treatment.Methods The clinical data of 92 breast cancer patients with axillary dissection were analyzed retrospectively.The surgical proce-dures were randomly chosen by patients,including 37 cases with ultrasonic scalpel and 55 cases with elec-trocautery.Both groups were compared in operation time,number of harvested lymph nodes,postoperative drainage in 24 h,seroma formation rate,and drain removal time.Results There were no significant differ-ences in operation time[(148.2 ±30.4)min vs(143.5 ±40.8)min],number of harvested lymph nodes (17 nodes vs 16 nodes),and drain removal time[(16.0 ±5.3)d vs(16.7 ±4.4)d]between ultrasonic scalpel group and electrocautery group(P >0.05 ).There were significant differences in postoperative drainage [(118.8 ±65.8)ml vs(159.2 ±71.3)ml]and seroma formation rate(8.1% vs 20%)between ultrasonic scalpel group and electrocautery group(P <0.01).Conclusion For breast cancer,ultrasonic scalpel is similar to electrocautery in axillary dissection,but it can reduce postoperative complications.

Two Cases of Electrocautery Incision Therapy Using an Insulated-tip Knife for Treatment of Symptomatic Benign Short-segment Colonic Stenosis Following Colonic Resection / 대한소화기학회지

Anastomotic stenosis of the colon is not an uncommon finding; however, its frequency varies from one study to another. Traditionally, postoperative colonic stenosis is managed surgically. However, endoscopic therapy has recently become the preferred treatment modality over traditional surgery. Good short-term success has been achieved with use of endoscopic balloon dilation; however, restenosis may occur over time in 14% to 25% of patients. The current report showed the effectiveness and usefulness of an insulated-tip knife (IT-knife) for electrocautery therapy of a patient with symptomatic anastomotic colonic stenosis.

Fires and Burns Occurring in an Electrocautery after Skin Preparation with Alcohol during a Neurosurgery

While there are reports regarding burns occurring to patients during the surgery, there are little reports concerning the incidents of the burns related to neurosurgical operations. Moreover, in Korea, even surveys and statistics on the incidents of burns in operating rooms are not known. This report explores burns occurring to a patient in an electrocautery scenario after disinfecting the surgical site with alcohol during the preparation of a neurosurgical operation in an operating room where there is much exposure to oxygen. The authors show a case of a 33-year-old male patient who undergoing evacuation of hematoma on occipital lesion, suffered second degree burns as a result of surgical fires.

Coblation vs. Electrocautery Tonsillectomy: A Prospective Randomized Study Comparing Clinical Outcomes in Adolescents and Adults

OBJECTIVES: Coblation is operated in low temperature, so it is proposed that tonsillectomy with coblation involves less postoperative pain and allows accelerated healing of the tonsillar fossae compared with other methods involving heat driven processes. However, the results of the previous studies showed that the effect of coblation tonsillectomy has been equivocal in terms of postoperative pain and hemorrhage. Though, most of the previous studies which evaluated coblation tonsillectomy were performed in children. Recently, electrocautery tonsillectomy has been used most widely because of the reduced intraoperative blood loss and shorter operative time compared to other techniques. This prospective study compared intraoperative records and postoperative clinical outcomes in adolescents and adults following coblation and electrocautery tonsillectomies. METHODS: Eighty patients over 16 years of age with histories of recurrent tonsillitis were enrolled. The patients were randomly allocated into coblation (n=40) and electrocautery tonsillectomy groups (n=40). All operations were performed by one surgeon who was skilled in both surgical techniques. Intraoperative parameters and postoperative outcomes were checked. RESULTS: Postoperative pain and otalgia were not significantly different between the two groups; however, there was a tendency towards reduced pain and otalgia in the coblation group. More cotton balls for swabbing the operative field were used introoperatively in the electrocautery group (P=0.00). There was no significant difference in postoperative hemorrhage, wound healing, commencement of a regular diet, and foreign body sensation between the groups. CONCLUSION: Only cotton use, which represented the amount of blood loss, was less in the coblation tonsillectomy group. Coblation tonsillectomy warrants further study with respect to the decreased postoperative pain and otalgia.
