The purpose of this study was to compare pulpal and periapical tissue reactions to electrosurgery versus formocresol pulpotomy techniques in the primary teeth of dogs. The study was conducted on 33 primary teeth of three mongrel dogs between the ages of one to three months. Each dog had three teeth treated by Formocresol Pulpotomy with Mechanical Coronal Pulp Removal (FC), three teeth treated b...
Chondrocytes are known to be thermal-sensitive, insofar as excessive temperatures may cause cellular death and promote the degeneration of articular cartilage (3). Therefore, it is imperative to determine and use the lowest possible settings of RF energy that will produce the desired effects (1-3). Similar to other studies conducted to characterize temperature changes for tissues treated using ...
OBJECTIVE To determine which treatment modalities for condylomata acuminata are associated with the lowest direct medical costs. DESIGN Cost-effectiveness analysis. SETTING Ambulatory private practice, primary or specialty care. PATIENTS OR OTHER PARTICIPANTS Adults with no presenting complaints other than condylomata acuminata. INTERVENTIONS Construction of a cost-effectiveness model. ...
Cautery is a process to coagulate tissues and seal blood vessels using heat. In this study, finite element modeling (FEM) was performed to analyze temperature distribution in biological tissue subject to a bipolar electrosurgical technique. FEM can provide detailed insight into the tissue heat transfer to reduce the collateral thermal damage and improve the safety of cautery surgical procedures...
OBJECTIVES Our aim was to evaluate a new electrosurgical instrument (Lap Loop device) that amputates the uterine corpus from the cervix during a laparoscopic supracervical hysterectomy (LSH) and to compare the time required for cervical amputation with traditional methods. METHODS This comparative trial was conducted at the University of Louisville and Norton Healthcare Hospitals, Louisville,...
Background and aim Strictures are a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. Post ESD, stricture develops during the process of scar formation, which is related to inflammation caused by ESD. We planned a study to evaluate whether certain electrosurgical unit modes could attenuate strictures after esophageal ESD. Methods A...
Electrosurgical vessel sealing has been demonstrated to have benefits for both patients and practitioners, but significant variation in the strength of the seal continues to be a concern. This study aims to examine the variation in electrosurgical seal quality along the length of a porcine common carotid artery and explore the relationships between seal quality, vessel size and morphology. Addi...
OBJECTIVE To evaluate surgical techniques, perioperative complications and outcome of laparoscopic surgery for unilateral and bilateral ovariectomy in mares. STUDY DESIGN Retrospective multicenter case series. ANIMALS Mares (n = 157). METHODS Indications for surgery were neutering, fertility problems, elimination of hormone-related abnormal behavior, ovarian tumors as well as nonregressiv...
This study compared functional and physical collateral damage to a nerve when operating a Codman MALIS Bipolar Electrosurgical System CMC-III or a CO2 laser coupled to a laser, with correlation to an in vitro model of heating profiles created by the devices in thermochromic ink agarose. Functional damage of the rat sciatic nerve after operating the MALIS or CO2 laser at various power settings a...
PURPOSE The purpose of this study was to evaluate the use of the Fischer cone biopsy excisor (FCBE) as the primary electrode for treatment of cervical dysplasia in a family medicine office. METHODS Retrospective analysis of cervical electrosurgical excision procedures in patients with cervical intraepithelial neoplasia (CIN) performed in our Family Medicine Center between 2002 and 2005. RES...
