Additionally, no cyclic or regular pattern has been observed in the colon more than 25 cm from the anal verge.

(1) The number and amplitude of rectal contractions recorded 15 cm from the anal verge.

The rectal balloon, 5 cm in length, was positioned with its distal edge 5 cm from the anal verge.

We secured the position of the prove by tape attached to the buttocks and measured the rectal CSA between 8.2 and 8.4 cm from the anal verge.

During this examination, three to four samples of flat rectal mucosa were taken from an area 10-15 cm from the anal verge and used for the proliferative studies described below.

Furthermore, in rectal prolapse, there is a sulcus present between the prolapsed bowel and the anal verge, whereas is hemorrhoidal disease there is no sulcus.

The anal verge is the distal end of the anal canal, forming a transitional zone between the skin of the anal canal and the perianal skin.

A minimum of four biopsy samples were obtained from each patient from macroscopically normal mucosa at the rectosigmoidal junction (about 20 cm from the anal verge), using standard forceps.

It was accepted that anal abuse may cause a range of signs, from surface skin damage, fissures, defects of anal verge, to severe lacerations, but that in our present state of knowledge, none of these in themselves, or in various clusters, establish with reasonable certainty that anal abuse has occurred.
