A photograph of the perineum. The patient is in lithotomy position and surgical drapes are applied. A 12 mm laparoscopic trocar is inserted into the anus and the trocar sleeve is fully advanced until the adjustable sleeve hub was pressed against the anus, creating a seal. A straight 35 mm laparoscopic grasper can be seen sliding beside the optical trocar into the anus. The seal is maintained by pressure from the anal sphincter.
