Abstract

Background/aims: In view of paucity of literature we analyzed our experience of acute recurrent pancreatitis (ARP) to study clinical profile and long-term outcome.

Methods: Over 13 years, 93 consecutive children (≤18 years) diagnosed to have ARP were included in this study. Magnetic resonance cholangiopancreatography was done at baseline and on follow-up. Common mutations for serine-protease-inhibitor (SPINK1 N34S), protease inhibitor (PRSS1 R122S) and cystic fibrosis transmembrane conductance regulator (CFTR deltaF508, 5T) were studied in 22 idiopathic cases.

Results: The median age of the children with ARP was 13 (10-14.5) years, 53 were males. Etiology included biliary in 14 (15%), pancreas divisum in 6 (7%), others in 3 (3.5%) and idiopathic in the remaining 70 (75%). SPINK1 mutation was found in 10/22 (45%) cases. Over a median follow-up of 25.5 (8.25-48) months, 37 (42%) of 88 (5 lost to follow-up) developed chronic pancreatitis (CP). On multivariate analysis idiopathic etiology (p<0.03), presence of SPINK1 mutation (p=0.01), longer follow-up (p<0.001) were associated with progression to CP.

Conclusions: Biliopancreatic structural/obstructive causes should always be looked for. It seems ARP is a precursor of CP and progression is associated with idiopathic etiology and presence of genetic mutations. Hence, patients with ARP should be kept on regular follow-up to detect CP.
