PURPOSE: To investigate the clinical manifestations and properties of remnant particles in the subconjunctival space after high-frequency radio-wave electrosurgery for conjunctivochalasis. METHODS: We performed a retrospective, observational case series with in vitro experimental imaging in nine eyes from eight patients who presented with small dark-gray lesions during follow-up after high-frequency radio-wave electrosurgery for conjunctivochalasis. General examination including slit-lamp examination and visual acuity testing was performed preoperatively and postoperatively. During follow-up, we evaluated remnant particles and any other complications including granuloma or conjunctival injection with slit-lamp photography and anterior optical coherence tomography. Coagulation tips were investigated with scanning electron microscope and energy dispersive X-ray spectroscopy to analyze the insulating electrode and assess changes to tips after repeated use. RESULTS: None of the patients included in this study experienced any change in visual acuity or major complications postoperatively. Small dark-gray lesions (0.3 to 0.5 mm in size) were observed in the inferior bulbar sub-conjunctival space in the location where high-frequency radio-wave electrosurgery had been performed. Cirrus high-definition optical coherence tomography images revealed focal hyper-reflection with a posterior shadow, suggesting foreign particles. Scanning electron microscopy and energy dispersive X-ray spectroscopy imaging analysis revealed peaks of carbon and fluorine complexes, consistent with the polytetrafluoroethylene coating on the electrode. CONCLUSIONS: There were no instances of inflammatory reaction, particle migration, or major complications due to particles. Physicians should be aware of the possibility of remnant polytetrafluoroethylene particles in subconjunctival tissue when using insulated coagulation tips subjected to repeat sterilization.

PURPOSE: PEAK PlasmaBlade is a recent and distinctive type of electrosurgical device. Previous studies have already documented some meaningful advantages of this device over conventional electrosurgery. This study compared the use of PEAK PlasmaBlade to standard electrosurgery in mastectomy and breast conservative surgery. The purpose was to test the impact of PEAK PlasmaBlade on the wound-healing process and on postsurgical complications in breast cancer surgery. METHODS: Sixty patients undergoing breast cancer surgery were enrolled. The PEAK PlasmaBlade was used for 20 of those. A standard electrosurgical device was used for the other 40 patients. The 2 groups were homogenous in age, body mass index, comorbidities and type of surgery. We recorded wound complications, serum drainage amount and duration of stay, blood loss, time of surgery, length of hospital stay, and total number of medications required. RESULTS: The 2 groups were not significantly different in terms of patient characteristics. A statistically significant reduction in incidence of seroma was observed in the PEAK group: only 10% versus 37.5% of the patients in the conventional electrosurgery group developed this complication (Fisher exact test, P = 0.034). CONCLUSION: Seroma is the most important wound complication in breast surgery. The research of new instruments that might reduce its incidence is desirable. In order to validate or deny the results of this study, it is necessary to enroll more subjects and to consider the impact of this device on axillary lymph node dissection.

INTRODUCTION: Hematuria is a common complication of transurethral electrosurgical procedures in the postoperative period. Presently, there is no standard diagnostic tool that will determine the degree of hematuria among postoperative catheterized patients. An innovative way of assessing the degree of hematuria is through the use of Hematuria Meter Application, a mobile device software program.
OBJECTIVE: The objective of this study was to determine the reliability of the Hematuria Meter Application as a diagnostic tool to assess the degree of hematuria in post-TURP and post-TURBT patients. This study aimed to determine if there is agreement between the Hematuria Meter Application readings and the RBCs counter per high power field by Direct Manual Quantitative Microscopy method and to determine if there is inter-observer agreement in using the Hematuria Meter Application between the patient or relative, nurse, intern and resident urologist.
METHODS: Using the Hematuria Meter Application, the color of the urine was graded by the patient or relative, resident, intern and nurse. Urine was then collected and sent to the laboratory for quantitative manual RBC counting under the microscope. Intraclass correlation coefficient (ICC) was used to determine teh agreement of the applicatin readings with RBC/hpf and inter-observer agreement among the observers.
RESULTS: From July 2014 to December 2015, a total of 159 eligible patients were included in this study. The average age was 69. Majority were males (91%). 118 patients out of 159 (74%) underwent TURP, while 41 patients (26%) underwent TURBT. The median age of patients who underwent TURP was 68 while the median age was 66 for patients who underwent TURBT.
The agreements of the Hematuria Meter Application readings with RBCs/hpf counted with Direct Manual Quantitative Microscopy method were almost perfect. ICC was 0.743 (p-value 0.000) in day 0 post-operative and 0.985 (p-value 0.000) in day 2 post-operative. Similarly, inter observer agreement was almost perfect and increasing at each period of assessment. In the immediate post-operative period, ICC was 0.832 (p-value 0.000). On second post operative day, ICC was 0.999 (p-value 0.000).
CONCLUSION: The Hematuria Meter Application is a reliable diagnostic tool in assessing the degree of hematuria in post-TURP and post-TURBT patients. There is inter-observer agreement in using this application.

Colorectal polypectomy is an effective method for prevention of colorectal cancer. Many endoscopic instruments have been used for colorectal polypectomy, such as snares, forceps, endoscopic clips, a Coagrasper, retrieval net, injector, and electrosurgery generator unit (ESU). Understanding the characteristics of endoscopic instruments and their proper use according to morphology and size of the colorectal polyp will enable endoscopists to perform effective polypectomy. I reviewed the characteristics of endoscopic instruments for colorectal polypectomy and their appropriate use, as well as the basic principles and settings of the ESU.

PURPOSE: In our study, the effects of harmonic scalpel, scalpel, and monopolar electrocautery usage on the health and healing of colon anastomosis after resection was investigated. METHODS: In this study, 120 female albino Wistar rats were divided into 3 groups each containing 40 rats. Group A, resection with scalpel; group B, resection with monopolar electrocautery; group C, resection with harmonic scalpel. The groups were divided into 4 subgroups consisting of 10 rats and analysed in the postoperative 1st, 3rd, 5th, and 7th days. Anastomotic bursting pressures, hydroxyproline levels and histopathological parameters were surrogate parameters for evaluating wound healing. RESULTS: The tissue hydroxyproline levels did not show any significant difference between the groups and subgroups. The mean bursting pressure of group A on the 5th day was significantly higher than groups B and C (P < 0.001). When the fibroblast and fibrosis scores were evaluated, scores of group C on the 5th day were significantly higher than the other groups, but the results of bursting pressures and biochemical parameters did not support the fibroblast and fibrosis scores. There were not any significant differences between the groups in other histopathologic parameters. CONCLUSION: The use of monopolar electrocautery needs more attention since the device causes tissue destruction. The obliterating effect of harmonic scalpel on luminal organs is an important problem, especially if an anastomosis is planned. Despite the disadvantages of scalpel, its efficacy on early wound healing is better than the other devices.

OBJECTIVE: This study was conducted using the human papillomavirus (HPV) DNA chip test (HDC), in order to determine whether the HPV genotype is a predictor of residual disease in a subsequent hysterectomy following a loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 3. METHODS: Between January 2002 and February 2015, a total of 189 patients who underwent a hysterectomy within 6 months of LEEP caused by CIN 3 were included in this study. We analyzed their epidemiological data, pathological parameters, high-risk HPV (HR-HPV) load as measured by the hybrid capture II assay, and HR-HPV genotype as measured by the HDC. A logistic regression model was used to analyze the relationship between covariates and the probability of residual disease in subsequent hysterectomy specimens. RESULTS: Of the 189 patients, 92 (48.7%) had residual disease in the hysterectomy specimen, CIN 2 in seven patients, CIN 3 in 79 patients, IA1 cancer in five patients, and IA2 cancer in one patient. Using multivariate analysis, the results were as follows: cone margin positivity (odds ratio [OR], 2.43; 95% CI, 1.18 to 5.29; p<0.05), HPV viral load > or =220 relative light unit (OR, 2.98; 95% CI, 1.38 to 6.43; p<0.01), positive endocervical cytology (OR, 8.97; 95% CI, 3.81 to 21.13; p<0.001), and HPV-16 or HPV-18 positivity (OR, 9.07; 95% CI, 3.86 to 21.30; p<0.001). CONCLUSION: The HPV-16 or HPV-18 genotype is a reliable predictive factor of residual disease in a subsequent hysterectomy following a LEEP for CIN 3.

The term electrosurgery refers to the passage of high-frequency alternating electrical current through the tissue, to achieve a specific surgical effect. It is used in everyday dermatologic practice for various purposes, including tissue dissection, bleeding control, and the removal of common skin lesions such as viral warts, melanocytic nevi, and cherry angiomas. Considering the nature of the device, adverse effects including skin burn and scarring can occur at any stage of the procedure. Therefore, it is essential that electrosurgery be performed by skilled and well-trained physicians. In this paper, we introduce a brief history of electrosurgery and present its categories and their clinical uses. In addition, the possible adverse effects and safety measures of electrosurgery are addressed.

BACKGROUND: Selective health benefit was introduced for decreasing economic burden of patients. Medical devices with economic uncertainty have been covered as selective health benefit by National Health Insurance since December 2013. We aimed to analyze impact of selective health benefit to medical expenditure and provider behavior focused on electrosurgery Cultrasonic shears, electrothermal bipolar vessel sealers for gastric cancer patients covered since December 2014. METHODS: We used the National Health Insurance claims data of 2,698 patients underwent gastric cancer surgery between August 2014 and March 2015. Medical cost and patient sharing per inpatient day were analyzed to verify that covering electrosurgery increased medical expenditure and changed provider behavior from open surgery to endoscopic or laparoscopic surgery. Additionally, we analyzed the claim rate of medical device or goods relating gastric endoscopic and laparoscopic surgery. RESULTS: Medical cost and patient sharing per inpatient day were increased after covering electosurgery as selective health benefit (39,724/1,421 won). However, there were no medical expenditure increases after adjusting claim of electosurgery and patient sharing was decreased 1,057 won especially. The coverage of selective health benefit did not increase the claim rate of medical device or goods related endoscopic or laparoscopic surgery, either. CONCLUSION: Covering electosurgery decreased patient economic burden and did not change of provider behavior. Expanding selective health benefit is needed to decrease economic burden of severe patients. Further study should evaluate the long term effect with accumulated data.

BACKGROUND/AIMS: Patients with cardiac implantable electronic devices (CIEDs) undergoing endoscopic electrosurgery (EE) are at a risk of electromagnetic interference (EMI). We aimed to analyze the effects of EE in CIED patients. METHODS: Patients with CIED who underwent EE procedures such as snare polypectomy, endoscopic submucosal dissection (ESD), and endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) were retrospectively analyzed. Postprocedural symptoms as well as demographic and outpatient follow-up data were reviewed through medical records. Electrical data, including preprocedural and postprocedural arrhythmia records, were reviewed through pacemaker interrogation, 24-hour Holter monitoring, or electrocardiogram. RESULTS: Fifty-nine procedures in 49 patients were analyzed. Fifty procedures were performed in 43 patients with a pacemaker, and nine were performed in six patients with an implantable cardioverter-defibrillator. There were one gastric and 44 colon snare polypectomies, five gastric and one colon ESDs, and eight ERCPs with EST. Fifty-five cases of electrical follow-up were noted, with two postprocedural changes not caused by EE. Thirty-one pacemaker interrogations had procedure recordings, with two cases of asymptomatic tachycardia. All patients were asymptomatic with no adverse events. CONCLUSIONS: Our study reports no adverse events from EE in patients with CIED, suggesting that this procedure is safe. However, because of the possibility of EMI, recommendations on EE should be followed.

Electrosurgical units are frequently employed during adenotonsillectomies to reduce both operation time and the amount of bleeding. Complications related to electrosurgical units have rarely been reported or taken into consideration by the majority of surgeons during operations. We report a case of an electrosurgical unit induced burn injury during an adenotonsillectomy. More specifically, the injury was a second-degree burn that occurred on the right oral commissure and the lip. The exact cause of the burn was not determined despite a close examination of the electrosurgical unit. An ointment was applied frequently to the lesion to prevent the wound from drying; the wound subsequently healed without any permanent scarring. Preventive methods, such as a thorough inspection of devices prior to surgery, the technique of using the third finger, and the use of a cheek retractor, may be necessary to avoid burn injuries caused by electrosurgical units.
