Moreover TST showed significant reductions compared to M-M in the rates of long-term complications such as fecal incontinence ( n = 3 vs n = 16 , P = 0.003 ) , difficult bowel movement ( n = 1 vs n = 9 , P = 0.011 ) , intractable pain ( n = 2 vs n = 12 , P = 0.007 ) , and anal discharge ( n = 3 vs n = 23 , P = 0.000 ) .
