This technique, described by Parks in 1982 [12,13], is performed with a perineal approach. Once the anal canal has been exposed with a Lone Star® type retractor, rectal mucosa is infiltrated with an adrenaline solution, favouring dissection and haemostasis. Mucosectomy is then performed starting a few millimetres above the dentate line up to the apex of the rectal stump.
The anastomosis is then sutured between the colon or the apex of the colonic reservoir, pulled down to the rectal muscular cuff, and the anal canal with slow absorption stitches .
