Postoperative changes of manometry after restorative proctocolectomy in Korean ulcerative colitis patients

Figure 1 Maximal squeezing pressure. MSP immediately decreased after surgery until 6 mo; however, it was recovered after 12 mo postoperatively. MSP: Maximal squeezing pressure.

Figure 2 Maximal resting pressure. The decreased MRP after surgery increased slightly after 12 mo; however, it did not recover to the preoperative value. MRP: Maximal resting pressure.

Figure 3 Rectal capacity. The decreased rectal capacity after surgery exceeded the initial volume up to 132.2 mL at 6-12 mo and increased up to 150 mL at 24 mo.

Figure 4 Bowel frequency. Bowel frequency gradually decreased at each interval and stabilized after 6-12 mo postoperatively.
