Bipolar radiofrequency ablation of genicular nerves in chronic knee pain: A novel technique for more complete sensory denervation.

Background: Monopolar radiofrequency ablation (MRFA) of the genicular nerves has been considered the main interventional treatment for chronic knee pain. However, the variable locations of these nerves could suggest that traditional MRFA of genicular nerves may be insufficient to cover the area needed to provide complete sensory denervation. For these reasons, some alternatives have been proposed to achieve an increase in the lesion area that offers better outcomes such a bipolar radiofrequency ablation (BRFA).

Same-day bidirectional endoscopy with nonanesthesiologist administration of propofol: safety and cost-effectiveness compared with separated exams.

Background And Aim: The safety and cost-effectiveness of a combination of esophagogastroduodenoscopy (EGD) and colonoscopy [or bidirectional endoscopy (BDE)] versus alternative-day EGD and colonoscopy when using nonanesthesiologist administration of propofol have never been evaluated.

Patients And Methods: This was a single-center prospective registry of consecutive American Society of Anaesthesiology class I-III outpatients undergoing EGD, colonoscopy, and BDE. Propofol was the sole sedative used.
