BMC Surgery

Table 3 Anal resting and squeezing pressures before and after surgery

	Baseline	Pressures at the time of activation		P
	Baseline	Filled cuff	Relaxed cuff	P
resting pressure (SD) [mmHg]	10.70 (8.32)	66.10 (14.27)	16.93 (6.15)	(*)
squeezing pressure (SD) [mmHg]	32.21 (21.58)	85.91 (21.44)	40.65 (17.03)	(*)

(*) All differences between the mean values were highly significant at P < 0.01.
(*) Baseline: value before the operation.
(*) Time of activation = 5–6 week after the operation.
