PURPOSE: In this study, we propose a novel laparoscopy-based renal denervation (RDN) system for treating patients with resistant hypertension. In this feasibility study, we investigated whether our proposed surgical instrument can ablate renal nerves from outside of the renal artery safely and effectively and can overcome the depth-related limitations of the previous catheter-based system with less damage to the arterial walls. METHOD: We designed a looped bipolar electrosurgical instrument to be used with laparoscopy-based RDN system...

Background This research fuses the experiences of a precancer diagnosis with the decision-making surrounding a vaccine that can protect against human papillomavirus strains that women may not have been exposed to. The interviewee cohort is of note as half the women were in their 30s and 40s and 75% were over the age of 26. These groupings are often overlooked in media discourses and narrative research surrounding human papillomavirus and the human papillomavirus vaccine. Purpose Womens' diagnoses and treatment experiences, including colposcopies, biopsies, and Loop Electrosurgical Excision Procedures, are chronicled to highlight a liminal, precancerous state-one in which they are not deemed healthy, but nor have they been diagnosed with cancer...

The use of respiratory protection, an important component of personal protective equipment (PPE) in healthcare, is dependent on the hazard and environmental conditions in the workplace. This requires the employer and healthcare worker (HCW) to be knowledgeable about potential exposures and their respective protective measures. However, the use of respirators is inconsistent in healthcare settings, potentially putting HCWs at risk for illness or injury. To better understand respirator use, barriers, and influences, the National Institute for Occupational Safety and Health (NIOSH) Health and Safety Practices Survey of Healthcare Workers provided an opportunity to examine self-reported use of respirators and surgical masks for targeted hazards...

The detection of high-grade intraepithelial lesions requires highly sensitive and specific methods that allow more accurate diagnoses. This contributes to a proper management of preneoplastic lesions, thus avoiding overtreatment. The purpose of this study was to analyze the value of immunostaining for p16 in the morphologic assessment of cervical intraepithelial neoplasia 2 lesions, to help differentiate between low-grade (p16-negative) and high-grade (p16-positive) squamous intraepithelial lesions. The direct medical cost of the treatment of cervical intraepithelial neoplasia 2 morphologic lesions was estimated...

BACKGROUND: Endopancreatic surgery (EPS) is an experimental minimally invasive technique for resection of pancreatic tissue from inside the pancreatic duct, accessed via the duodenum and papilla. It is proposed as an alternative to duodenum-preserving pancreatic head resection in benign diseases such as chronic pancreatitis (CP). This study evaluated the use of EPS for resection of pancreatic duct stenoses. Moreover, greenlight laser (GLL) and monopolar electrosurgical device (MES) were compared as resection tools for EPS...

BACKGROUND: The standard treatment for cervical adenocarcinoma in situ (AIS) is hysterectomy, which is a more aggressive treatment than that used for squamous intraepithelial lesions. Several previous studies have primarily demonstrated that the loop electrosurgical excision procedure (LEEP) is as safe and effective as cold knife cone (CKC) biopsy when AIS is unexpectedly found in a loop excision. This study evaluated the safety of LEEP as the initial treatment for patients with AIS who were strictly selected and evaluated before and after loop resection...

Hysteroscopy is performed to view and treat pathology within the uterine cavity and endocervix. Diagnostic hysteroscopy allows visualization of the endocervical canal, endometrial cavity, and fallopian tube ostia. Operative hysteroscopy incorporates the use of mechanical, electrosurgical, or laser instruments to treat intracavitary pathology and perform hysteroscopic sterilization procedures. Selection of a distending medium requires consideration of the advantages, disadvantages, and risks associated with various media as well as their compatibility with electrosurgical or laser energy...

The evolution of precancerous cervical lesions is poorly understood. A widely held model of cervical intraepithelial neoplasia grade 3 (CIN3) development is sequential progression from normal through CIN1 and CIN2 to CIN3. Another hypothesis, the "molecular switch" model, postulates that CIN3 can evolve directly from human papillomavirus (HPV)-infected normal epithelium without progressing through CIN1 and CIN2. To shed light on this process, we compared DNA methylation of selected human biomarkers and HPV types in two groups of CIN1: CIN1 that were near or adjacent to CIN3 (adjacent-CIN1) and CIN1 that were the principal lesions with no CIN3 detected (principal-CIN1)...

BACKGROUND: Survival from ovarian cancer (OC) is improved with surgery, but surgery can be complex and tumour identification, especially for borderline ovarian tumours (BOT), is challenging. The Rapid Evaporative Ionisation Mass Spectrometric (REIMS) technique reports tissue histology in real-time by analysing aerosolised tissue during electrosurgical dissection. METHODS: Aerosol produced during diathermy of tissues was sampled with the REIMS interface. Histological diagnosis and mass spectra featuring complex lipid species populated a reference database on which principal component, linear discriminant and leave-one-patient-out cross-validation analyses were performed...

Anti-adhesion surfaces with high-temperature resistance have a wide application potential in electrosurgical instruments, engines, and pipelines. A typical anti-wetting superhydrophobic surface easily fails when exposed to a high-temperature liquid. Recently, Nepenthes-inspired slippery surfaces demonstrated a new way to solve the adhesion problem. A lubricant layer on the slippery surface can act as a barrier between the repelled materials and the surface structure. However, the slippery surfaces in previous studies rarely showed high-temperature resistance...

Electrosurgery produces surgical smoke. Different tissues produce different quantities and types of smoke, so we studied the particle characteristics of this surgical smoke in order to analyze the implications for the occupational health of the operation room personnel. We estimated the deposition of particulate matter (PM) from surgical smoke on the respiratory tract of operation room personnel using clinically relevant tissues from Finnish landrace porcine tissues including skeletal muscle, liver, subcutaneous fat, renal pelvis, renal cortex, lung, bronchus, cerebral gray and white matter, and skin...

Cutaneous ulceration is a difficult medical problem and a major source of morbidity for patients. In the surgical treatment of ulcers, debridement is the first step, and it can be carried out using several surgical tools. Recently, new surgical devices have emerged using plasma-mediated electrical discharges with a lower peak temperature. A prospective single-blind trial was conducted on chronic ulcers not responsive to common non-surgical management. Patients were randomly separated into 2 groups: Group A received surgical debridement with conventional electrocautery, and Group B received surgical debridement using the plasma-mediated device...

Urinary tract injuries are unfortunate complications of pelvic surgery. With the increasing popularity of minimally invasive surgery, a thorough understanding of electrosurgical instrumentation and their thermal spread is important to reduce patient injuries. The index patient was a 50 year old woman who underwent a supracervical hysterectomy 5 years prior to her presentation with pelvic pain and dysuria. When her symptoms failed to improve despite antibiotic and analgesic therapy, an abdominal CT scan revealed an ovarian cyst and ascites...
