Abstract

Arthroscopy has benefited greatly by the development of the miniaturized television camera. Not only is televised arthroscopy a valuable teaching aid, but it also promises to shorten and make more efficient many of the necessary operative procedures on the knee. A method for accomplishing this is presented.

[A new method for the management of perforated veins in the lower extremities].

Elimination of incompetent perforating veins is the effective therapeutic method in the treatment of lower leg ulceration and trophic skin disorders associated with chronic venous insufficiency. The subfascial endoscopic ligation is a new surgical method to treat patients with incompetent perforating veins. 19 patients with severe chronic venous insufficiency or protracted venous ulceration of lower leg were treated. Through an incision of the skin the proximal 1/3 of the lower leg-far away from the dermatosclerotic area-an endoscope is inserted after which the perforating veins are ligated by clips under direct vision. The method is recommended due to its reduced invasiveness and the fair results.

Initial experience with a real-time video processor for enhancing endoscopic image contrast.

BACKGROUND: An initial experience using a digital video processor to enhance contrast in endoscopic images in real-time is described. METHODS: Endoscopic images were examined with a system using locally adaptive processing to balance variations in illumination and sharpen fine features in real-time. For comparison, indigo carmine dye, a popular exogenous contrast agent, was applied to one patient. RESULTS: In general, contrast-enhanced images appeared to contain more mucosal detail, with reduced glare and features in shadowed areas revealed. When used in conjunction with indigo carmine, the enlarged crypt openings in an aberrant crypt focus were visible, the first such detection in vivo without the use of magnifying endoscopy. CONCLUSIONS: Real-time video contrast enhancement during endoscopic procedures appears to provide excellent mucosal detail and improve contrast in a clinically useful manner.
