Background and aim Follow-up computed tomography (CT) in patients with acute pancreatitis has been advocated but rarely studied. The aim of this study was to determine whether follow-up CT for acute pancreatitis might be helpful in establishing the prognosis or complications, and in determining a selected subgroup of patients for whom computed tomography could be beneficial. Methods Between January 2010 and December 2012, patients with acute pancreatitis who underwent follow-up CT in the outpatient department between one and three months after discharge were retrospectively enrolled. Events discovered on follow-up CT were defined as newly developed or increased pancreatic collection such as pseudocyst or walled off necrosis, and diagnosis of pancreatic cancer. Results Ultimately, 106 asymptomatic patients were enrolled (mean age 50.24 ± 16, 74.5% male, 31.1% moderately severe and severe acute pancreatitis). The median duration of follow-up CT was 69 (31-90) days. On follow-up CT, 23 patients showed events (2 pancreatic cancer, 21 increasing or developed pancreatic collections). In multivariate analysis, the predictive factors for events on follow-up CT were CTSI ≥3 (OR 4.46, CI 1.08-18.43, p = 0.039) and BISAP ≥ 2 (OR 4.83, CI 1.08-21.55, p = 0.039). Conclusions Follow-up CT within three months after discharge may be helpful for acute pancreatitis patients with CTSI ≥ 3 points or BISAP score ≥ 2 points.
