The authors present the characteristics and the advantages deriving from the use of a new accessory to be fitted on the isostatic anal retractor in order to further improve visualisation of the operative field during the treatment of pelvic and anal pathologies. The isostatic anal retractor consists of a system of rotating rings and valves which are positioned with surgical stitches on the patient's buttocks. The new accessory is characterised by one or more elastic systems that can be fixed to the retractor metal ring and attached by means of curved needles to flaps of anal mucosa, affording enhanced visibility of the operative field. A total of 25 patients--15 with mucosal prolapse, 5 with haemorrhoids and 5 with anal fistulas--were treated surgically for their respective pathologies using the isostatic anal retractor and the new accessory. None of the patients observed complained of complications related to the use of the anal retractor or the accessory. In 95% of patients submitted to the procedures using the new accessory, visualisation of the operative field was improved as compared to the use of the anal retractor alone. In 5 patients it was possible to use the new accessory advantageously applied only to the external ring of the retractor. Our operative team judged the use of new accessory to be satisfactory in all cases in which greater visibility of the operative field is required. Use of the new accessory use in association with the isostatic anal retractor proved efficacious for achieving better therapeutic results with the treatments performed, permitting greater operator autonomy and enhancing visualisation of the operative field with respect for sphincter function. more...

In this paper the authors present the technical characteristics and clinical results of a new anal retractor designed and produced by them. This new instrument, made of disposable material, allows the proctologist to operate completely alone thanks to a system of rotating rings which are fixed directly to the patient's legs by means of Velcro bands. Twenty consecutive patients with proctological diseases have been operated on to date with the new device. No complications were registered in our series. The rotation movement and overall stability of the retractor were judged sufficient in 6 cases and good in 14. Opening of the device proved asymmetrical in 20% of the cases without this affecting the surgical technique. Our surgical team considered the prototype ideal, and the operative space available to the surgeon much greater than with previous retractor models. No limitations have been observed in treating any of the proctological diseases. The possibility of performing sutures in the anal canal was judged to be good. In conclusion, our new anal retractor would appear to guarantee greater autonomy in proctological surgery with much better clinical and therapeutic results and lower costs. more...
