Long-Term Follow-Up and Outcome of Pediatric Acute Pancreatitis: A Multicenter Study

Objective: Over the past decades, the incidence of acute pancreatitis is increasing, but the progression of acute recurrent pancreatitis and chronic pancreatitis is still not well documented in children. The aim of this multicenter study is to delineate the changes that occur in a certain time period in the course of childhood pancreatitis.Materials and Methods: The data of consecutive patients hospitalized with acute pancreatitis between 2010 and 2017 in 4 different pediatric gastroenterology units were reviewed. The clinical characteristics of the disease were defined.Results: A total of 165 patients (55.2% female) were included. Over the years, the rate of acute pancreatitis admissions increased while the duration of hospitalization decreased (P < .05). Nearly two-thirds of the patients with acute pancreatitis resolved spontaneously, 30.9% and 4.3% of the cases developed acute recurrent pancreatitis and chronic pancreatitis, respectively. Furthermore, 27.4% patients with acute recurrent pancreatitis progressed to chronic pancreatitis, and eventually, 12.7% of cases developed chronic pancreatitis within 3-4 years. Local complications developed in 13.3% of the patients with pancreatitis in this cohort.Conclusion: The result of this study confirmed the increased incidence of acute pancreatitis in recent years. Conversely, the length of hospital stay decreased over the years. Patients with pancreaticobiliary abnormalities or genetic risk factors had a higher rate of progression to acute recurrent pancreatitis or chronic pancreatitis. Therefore, genetic testing and radiological imaging should be considered early in the follow-up of patients with acute pancreatitis having risk factors for progression to acute recurrent pancreatitis/chronic pancreatitis.
