Peritoneoscopy is a very important technique for diagnosis of intraabdominal diseases. However, until recently conventional peritoneoscopy required hospi-talization and use of the operating room. A new peritoneoscope has been deviced by the Olympus Optical Company of Japan which incoropor-ates a fiber conduit of 1.5mm diameter, composed of 20, 000 fibrils. The effective lenghth of the instrument is 109mm with an overall diameter of 3.0mm. The outside diameter of the trocar used is 3.4mm, inside diameter 3.2mm. Cold light is supplied by a xenon letup. The objective consists of a Mini-Lens with a view field of 65° and forward oblique view angle of 16°. One ocular lens is supplied for observation (30X) and one for photo-graphy (10X). Photography is performed by Olympus Pen F Camera with shutter speeds between 1/15 and 1/30 sec.. With the new small diameter peritoneoscope we have been able consistent lyto carry out peritone-oscopy at the patient's bedside, avoiding also need for incision and suture. Several examinations were performed in the outpatient department and patients allowed to return home after a period of observation (3-4 hrs.). Our case series is still limited but no complications were observed so far. In our opinion this new instrument will make peritoneoscopy an easier and. safer procedure and will be very useful to gastroenterologists and hepatologists.
