[Incidence of recurrence following surgery of perforating and non-perforating complications in Crohn disease].

From 1980-1987 131 patients were operated for Crohn's disease. Among these 73 patients had perforated (PC) free perforation, abscess, fistula, and 47 had nonperforating complications (NC). Ileums, bleeding, stenosis reoperations (58 pts, 44%) were seen more often in the PC-group (57%) compared to 31% in the NC-group. Furthermore there was a high concordance in the indication for the initial and subsequent operations.
