^aIncision at operation was quoted from the operation record. Incisions in patients 1, 4–8, and 11 were commenced above the dentate line; however, the detailed distances were unknown
^bDBAI distance between the anastomosis and intersphincteric groove
^cThis patient had Waardenburg syndrome and developmental delay
