Acute idiopathic pancreatitis preceding diagnosis of Crohn's disease. Description of three cases.

UNLABELLED

Acute idiopathic pancreatitis seems to represent a rare extraintestinal manifestation of Crohn's disease usually appearing after the establishment of diagnosis of the intestinal disorder. The aim of this study was to describe the clinicoepidemiological characteristics and clinical course of three patients with Crohn's disease who developed acute idiopathic pancreatitis years before the establishment of diagnosis intestinal disease.

DESCRIPTION OF CASES

All patients were suffering from Crohn's disease. In all patients, an extensive work-up aiming to identify an etiological factor involved in the pathogenesis of acute pancreatitis was negative. The main clinical characteristics of the patients were the young age, the mild or moderate degree of severity of pancreatitis, and the concurrent involvement of small and large bowel from Crohn's disease in two of them. There was no preference for either male or female sex. The course of pancreatitis was favorable in all patients. During the follow-up period, ranging from 2 to 8 years, no exacerbation of pancreatitis was noticed.

CONCLUSION

This case-series suggests that acute idiopathic pancreatitis could precede diagnosis of Crohn's disease. Clinicians must bear in mind the possibility of the existence of Crohn's disease when they are confronting a young patient with clinical and laboratory features of acute idiopathic pancreatitis.
