Core Tip
Core tip: Although there has been an increase in the prevalence of ulcerative colitis (UC) and the numbers of UC surgery in Asian countries, studies on the functional outcomes of restorative proctocolectomy (RPC) or the quality of life in Asians are still deficient. Most UC studies on functional outcomes were done in Westerners. The authors found that maximal squeezing pressure, rectal capacity, and bowel frequency were stabilized at 12 mo after RPC. Although the decreased MRP was improved after 18 mo, it did not completely recover to the preoperative value. These findings in Korean patients with UC were not different from those in Western patients with UC.
