Introduction: In pediatric Crohn's disease ileocecal resection is performed reluctantly as postoperative recurrence is frequent. Anti-tumor necrosis factor (TNF) therapy reduces postoperative recurrence rates but increases the risk for infections.
Materials and methods: We retrospectively reviewed pediatric Crohn's disease patients who underwent ileocecal resection in our center. We compared disease activity and z-scores for height, weight, and body mass index of patients, who continuously received perioperative anti-TNF therapy (TNF + ), with those who did not (TNF-).
Results: Of 29 patients (48% females), 13 and 16 were grouped to TNF+ and TNF-, respectively. Patients' characteristics did not differ between groups, except a longer follow-up time in TNF-. We saw significant postoperative improvement but no normalization in z-scores for weight (1.78 vs. 0.77, p < 0.001), body mass index (1.08 vs. 0.22, p < 0.001), and height (0.88 vs. 0.66, p < 0.001). Disease activity improved significantly more in patients receiving anti-TNF therapy (moderate improvement in 83% vs. 31%, p = 0.02). Endoscopic recurrence was more frequent in patients without anti-TNF therapy (80% vs. 20%; p = 0.023), but endoscopic follow-up was incomplete. There was no increase of infections under perioperative anti-TNF therapy (1 patient each; p = 1.000).
Conclusion: In patients with localized Crohn's disease an ileocecal resection leads to short-term postoperative improvement of disease activity, body mass index, weight, and growth. For relevant catch-up growth an earlier intervention is necessary. Continuous perioperative anti-TNF therapy had no increased risk of perioperative infections.
