The increase in minimally invasive procedures performed has been accompanied by an increase in the incidence of associated iatrogenic complications. A significant portion of these complications are electrosurgical in nature—stemming from surgical pilot error, improper use or maintenance of electrosurgical instrumentation, or from electrosurgical burns that occur beyond the surgeon's direct visi...

Two types of applicators, an inductive applicator and capacitive electrodes, are used to compute the temperature elevation during the treatment of the shoulder, hip and spine in a numerical male model (NORMAN). The used thermal model is based on the Pennes Equation and has been extended by additional thermoregulatory mechanism. The blood flow and metabolic rate are elevated as a function of the...

Introduction. Milligan-Morgan haemorrhoidectomy performed with LigaSure system (LS) seems to be mainly effective where a large tissue demolition is required. This randomized study is designed to compare LigaSure haemorrohidectomy with conventional diathermy (CD) for treatment of IV-degree haemorrhoids. Methods. 52 patients with IV-degree haemorrhoids were randomized to two groups (conventional ...

OBJECTIVE To determine the efficacy and morbidity of fine loop diathermy excision of the cervical transformation zone as applied to the management of outpatients with abnormal cervical smears. DESIGN Prospective programme trial with six month follow up. SETTING Two hospital based colposcopy clinics. PATIENTS 616 Patients aged 16-60 with abnormal cervical smears. INTERVENTIONS After colp...

Hypertrophy of the inferior turbinates are the major cause of nasal obstruction. CO2 lasers have been used to reduce the size of the inferior turbinates over the last 20 years. However, the many techniques of delivery of the laser show that there is no one standard method reducing the size of the turbinates. We now describe how the laser can be applied directly to the turbinates using a handpie...
