Chronic Pancreatitis

Official guideline from the American College of Gastroenterology.

Diagnosis

Diagnosis
Strong recommendation
Low quality evidence
We recommend CT or MRI for the first-line diagnosis of CP. Either test should be the first choice for the diagnosis of CP. EUS, because of its invasiveness and lack of specificity, should be used only if the diagnosis is in question after cross-sectional imaging is performed.
Conditional recommendation
Low quality evidence
We suggest performing s-MRCP when the diagnosis of CP following cross-sectional imaging or EUS is not confirmed and the clinical suspicion remains high.
Conditional recommendation
Very low quality evidence
We suggest histological examination as the gold standard to diagnose CP in high-risk patients when the clinical and functional evidence of CP is strong, but imaging modalities are inconclusive.

Etiology

Etiology
Strong recommendation
Low quality evidence
We recommend genetic testing in patients with clinical evidence of a pancreatitis-associated disorder or possible CP in which the etiology is unclear, especially in younger patients.

Management

Natural History and Clinical Symptoms
Strong recommendation
Very low quality evidence
We recommend alcohol cessation in patients with CP.
Strong recommendation
Very low quality evidence
We recommend smoking cessation in patients with CP.
Management of Pain
Strong recommendation
Moderate quality evidence
We recommend surgical intervention over endoscopic therapy in patients with obstructive CP for the long-term relief of pain if first-line endoscopic approaches to pancreatic drainage have been exhausted or unsuccessful.
Conditional recommendation
Moderate quality evidence
We suggest considering the use of antioxidant therapy for CP with pain, although the benefit of pain reduction is likely limited.
Conditional recommendation
Low quality evidence
We do not suggest the use of pancreatic enzyme supplements to improve pain in CP.
Conditional recommendation
Very low quality evidence
We suggest considering celiac plexus block for treatment of pain in CP.
Management of Exocrine Pancreatic Insufficiency
Conditional recommendation
Low quality evidence
We suggest PERT in patients with CP and exocrine pancreatic insufficiency to improve the complications of malnutrition.
