A questionnaire survey of ten institutions in Japan revealed that restorative proctocolectomy accounted for 81.8% of the surgical procedures performed in patients with UC in the last 5 years (1989-1993); ileoanal anastomosis (IAA) and ileo-anal canal anastomosis (IACA) were performed in 63% and 33% of these patients, respectively. Comparison of the two series showed that IACA was technically simpler and yielded better continence, but that it entailed a potential risk of recurrence of the disease in the remaining anal canal mucosa. Although IACA seems to be a useful surgical option for UC, until the long-term outcome of the procedure can be elucidated. It may be better regarded as a very low variation of IRA rather than as an improved technical version of IAA.
一项针对日本十家机构的问卷调查显示，在过去五年（1989 - 1993年）中，恢复性直肠结肠切除术占溃疡性结肠炎患者所施行外科手术的81.8%；这些患者中分别有63%和33%接受了回肠肛管吻合术（IAA）和回肠 - 肛管通道吻合术（IACA）。对这两组病例的比较表明，IACA在技术上更简单，控便效果更好，但在剩余肛管黏膜中存在疾病复发的潜在风险。尽管IACA似乎是溃疡性结肠炎一种有用的手术选择，但在该手术的长期结果得以阐明之前，或许将其更好地视为IRA的一种非常少见的变体，而非IAA的改良技术版本。
