潰瘍性大腸炎の内視鏡所見

Colonoscopic Findings in Patients with Ulcerative Colitis

潰瘍性大腸炎（UC）の診療は内科的治療の飛躍的進歩によって，より緻密さが要求されるようになってきている．大腸内視鏡検査は，UC診療の基軸となるもので，鑑別診断，重症度や罹患部位の把握，合併症の診断などに有用である．検査施行に当たっては，前処置や挿入部位など様々な事項を症例に応じ，臨機応変に行い，必要な情報を的確に入手する．image enhanced endoscopy（IEE）や分子イメージングは，この分野にさらなる進化を将来もたらす可能性がある．

　Breakthrough development of treatment for ulcerative colitis brought the needs of precise clinical practice recently. Colonoscopy is essential examination for differential diagnosis, understanding of the activity or distribution of inflammation and for other complications. It is important for the flexibility of preparation and the insertion site according to the character of each individual case, and for access to the findings accurately. Image enhanced endoscopy or molecular imaging techniques might bring new developments in the near future.
