1.   The findings of the present study lend further support to the concept that the entire anal canal should be preserved.

2.   With a dissecting microscope, the epithelium of the anal canal was removed together with the submucosa.

3.   Two independent groups of researchers have reported the presence of a rectal motor complex, but no patterns of cyclic motility have been reported from the anal canal.

4.   To stabilise the position of the tube, two balloons surrounding the anal canal were inflated.

5.   On presentation of faeces to the proximal anal canal, the duration of the squeezing effort may not be sufficient for rectal adaptation.

6.   The procedure would involve inserting a swab into the anal canal.
