LAPAROSCOPY IN TELEOSTS. PRELIMINARY FINDINGS

Laparoscopy is a surgical technique that permit to look into the abdominal cavity, using a specific instrumentation, through small incisions; for this reason it must be considered as a surgical method with lower invasiveness than traditional abdominal surgery. This study is aimed at evaluating and adapting the general principles of the technique to teleosts. The study was performed on 15 subjects, belonging to different species and weight: five meagres (Argyrosomus regius), five carps (Cyprinus carpio), five common pandoras (Pagellus erythrinus). All the fishes examined were anaestetized with MS 222 (Tricaine methansulfonate) solution. The laparoscopy was carried out using a rigid cistoscope with an oblique vision at 30 degrees, 1.9 mm in diameter, connected with a portable video system Medi PackTM by Storz. Our results confirm that laparoscopy could represent an imaging technique with high sensitivity to show and evaluate celomic organs.
