The American College of Gastroenterology states that there is no definitive benefit to screening patients with chronic pancreatitis for pancreatic ductal adenocarcinoma, even in those at high risk for pancreatic malignancy due to genetic or environmental risk factors.[85]Gardner TB, Adler DG, Forsmark CE, et al. ACG clinical guideline: chronic pancreatitis. Am J Gastroenterol. 2020 Mar;115(3):322-39.

The American Gastroenterological Association recommends that pancreatic cancer screening should be considered in patients with hereditary pancreatitis; screening should be initiated at age 40 years in CKDN2A and PRSS1 mutation carriers with hereditary pancreatitis.[259]Aslanian HR, Lee JH, Canto MI. AGA Clinical practice update on pancreas cancer screening in high-risk individuals: expert review. Gastroenterology. 2020 Jul;159(1):358-62.

International and UK guidelines recommend that patients with hereditary pancreatitis with inherited PRSS1 mutations should undergo surveillance for pancreatic cancer.[260]Greenhalf W, Lévy P, Gress T, et al. International consensus guidelines on surveillance for pancreatic cancer in chronic pancreatitis. Recommendations from the working group for the international consensus guidelines for chronic pancreatitis in collaboration with the International Association of Pancreatology, the American Pancreatic Association, the Japan Pancreas Society, and European Pancreatic Club. Pancreatology. 2020 Jul;20(5):910-8.

Recommended screening and surveillance tests are endoscopic ultrasonography (EUS) or magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP).
One randomised controlled trial of patients with chronic pancreatitis who received extracorporeal shock wave lithotripsy for pancreatic stones >5 mm in diameter reported that administration of rectal indometacin before the procedure reduced the risk of post-procedure pancreatitis, compared with placebo.[262]Qian YY, Ru N, Chen H, et al. Rectal indometacin to prevent pancreatitis after extracorporeal shock wave lithotripsy (RIPEP): a single-centre, double-blind, randomised, placebo-controlled trial. Lancet Gastroenterol Hepatol. 2022 Mar;7(3):238-44.
