Endoscopic images of postoperative recurrence. All different situations of modified Rutgeerts score are illustrated. A normal mucosa of the neoterminal ileum is present in [a] [Rutgeerts i0]. A patient with only two aphthous ulcers in the neoterminal ileum [b] is also considered in endoscopic remission [Rutgeerts i1]. In [c], a single ulcer <1 cm is confined to the ileocolonic anastomosis [Rutgeerts i2a]. In [d], mild recurrence is detected with more than five aphthous ulcers in the neoterminal ileum with normal intervening mucosa [Rutgeerts i2b]. Neoterminal ileitis with diffuse aphthous lesions is shown in picture [e] [Rutgeerts i3]. Severe endoscopic recurrence [Rutgeerts i4] with large ulcers for 10 cm of neoterminal ileum, with non-passable stenosis and spontaneous bleeding, is illustrated in [f].
