The course of Crohn's disease is quite variable in children. To assess
the frequency and indications for surgery with current medical therap
y, the authors reviewed the cases of 204 children (ages, 0.2 to 18.8 y
ears at diagnosis, median, 12.8 years) who had Crohn's disease treated
at a single institution from December 1968 to January 1994, with a me
dian of 3.8 years of follow-up (range, 0.0 to 22.2 years), Ninety-four
children (46%) required surgical resection for the following indicati
ons: (1) failure of medical therapy with persistent symptoms or growth
retardation (n = 44, 47%), (2) intraabdominal abscess or perforation
(n = 15, 16%), (3) fistula formation (n = 13, 14%), (4) obstruction (n
= 15, 16%), (5) hemorrhage (n = 4, 4%), and (6) appendectomy at explo
ration for diagnosis (n = 3, 3%). The probability for surgery 3 years
after diagnosis is 28.8% and by 5 years is 47.2%. Resections included
ileocolectomy (71 children), colectomy (n = 16), small bower resection
(n = 4), and appendectomy (n = 3). Fourteen fistulas in 13 children r
equired surgical intervention (7 enteroenteral, 3 enterovesical, 2 ent
erovaginal, and 2 enterocutaneous). The median duration from diagnosis
to surgery for the fistulas was 2.6 years (range 0.1 to 9.8 years). F
orty patients experienced recurring disease after resection during fol
low-up with a median of 1.8 years (range 0.4 to 18.1 years). The autho
rs found that the course of the disease was unpredictable, with some c
hildren requiring early surgical intervention and others continuing wi
th medical therapy for years. Copyright (C) 1997 by W.B. Saunders Comp
