UC

One previous clinical study suggested that UC-PSC patients reveal a high rate of rectal sparing and backwash ileitis.

此前有临床分：UC-PSC患者直不受累和发生反流性回炎的几率高。

Conclusion: Total coloproctectomy is best procedure to treat FAP and UC and postoperative effect is better in IPAA.

全结直切除术是FAP、UC的首选术式，而IPAA术后效果较好。
