[Guiding tubes for transanal use of circular suture instruments (author's transl)].

Guiding tubes of three different diameters with the corresponding "ghost heads" are of considerable help in rectal surgery, as they facilitate anorectal intubation, evacuation of residual gas after peroperative coloscopy and sub-peritoneal dissection of the rectum opposite the future anastomotic line. After withdrawal of the ghost head and circular suture instrument selected (EEA, ILS or SPU) is introduced aseptically and without trauma through the tube, and the various adjustment markings of the EEA instrument can easily be checked at any moment during the last stages of anastomosis.
