Background and aims: Digestive perianastomotic ulcerations (DPAU) have been occasionally reported as late complications of neonatal or childhood surgery.
Methods: We report here a series of 14 new cases.
Results: Cases were revealed by severe anemia, diarrhea, abdominal pain and growth failure in average 11.5 years after surgery. Ulcerations were most often multiple (n=11), located on the upper part of ileocolonic anastomoses (n=12) and difficult to treat. No granulomas were seen but lymphoid follicles were frequent. In addition, either ASCA or ANCA were positive in 4/9 tested patients and 8/11 genotyped patients exhibited a NOD2 mutation (P<0.0002 when compared to French healthy controls).
Conclusion: Altogether, these findings argue for common physiopathological features between DPAU and Crohn's disease and for a prospective follow-up of selected operated children to explore the early events involved in gut inflammatory lesions.
