Ileal pouch-anal anastomosis has clearly diminished the role of colectomy and ileorectal anastomosis (IRA) in the management of patients with ulcerative colitis. Nonetheless, IRA probably still has an appropriate place in highly selected patients, and many others maintain an "out of circuit" rectal remnant after subtotal colectomy. Although symptomatic proctitis is the most common reason for completion proctectomy, these patients are also at a significant risk to develop rectal cancer. Routine surveillance appears to be warranted.
回肠储袋肛管吻合术已明显降低了结肠切除术和回肠直肠吻合术(IRA)在溃疡性结肠炎患者治疗中的作用。尽管如此,IRA在经过严格筛选的患者中可能仍占有一席之地,而且许多患者在次全结肠切除术后仍保留“未纳入手术范围”的直肠残端。虽然症状性直肠炎是完成直肠切除术最常见的原因,但这些患者发生直肠癌的风险也很高。常规监测似乎是必要的。
