What is the management approach for acute and chronic pancreatitis?

From the Guidelines

The management of acute and chronic pancreatitis should prioritize supportive care, symptom control, and addressing complications, with a focus on early oral feeding, pain management, and nutritional support, as recommended by the most recent guidelines 1. The approach to managing acute pancreatitis involves:

• Aggressive IV fluid resuscitation, although the optimal rate is still debated, with recent studies suggesting goal-directed fluid therapy 1
• Pain control with opioid analgesics
• Early oral feeding within 24-48 hours if tolerated, as recommended by the American Gastroenterological Association 1
• Nutritional support via enteral feeding, preferably nasojejunal, for severe cases
• Monitoring for complications like pancreatic necrosis or pseudocysts For chronic pancreatitis, the management strategy includes:
• Pain management using a stepwise approach from acetaminophen and NSAIDs to opioids if necessary
• Pancreatic enzyme replacement therapy (PERT) to help with maldigestion and malabsorption
• Nutritional support with a low-fat diet, abstinence from alcohol, and supplementation of fat-soluble vitamins (A, D, E, K)
• Endoscopic interventions for strictures or stones, and surgery reserved for intractable pain or complications
• Addressing underlying causes, particularly alcohol cessation, and managing diabetes which commonly develops It is essential to note that the management of pancreatitis requires a comprehensive approach that addresses the inflammatory process, prevents complications, and improves quality of life for patients with these challenging pancreatic disorders, as emphasized by recent guidelines 1.

From the FDA Drug Label

The final analysis population was limited to 29 patients; 3 patients were excluded due to protocol deviations. A randomized, double-blind, placebo-controlled, parallel group study was conducted in 54 adult patients, aged 32 to 75 years, with exocrine pancreatic insufficiency due to chronic pancreatitis or pancreatectomy (Study 4)

The management approach for acute and chronic pancreatitis is not directly addressed in the provided drug label. However, the label does discuss the treatment of exocrine pancreatic insufficiency due to chronic pancreatitis with pancreatic enzyme replacement therapy, such as CREON.

• The study results show that CREON is effective in improving the coefficient of fat absorption (CFA) in patients with exocrine pancreatic insufficiency due to chronic pancreatitis or pancreatectomy 2.
• The dosage of CREON used in the study was 72,000 lipase units per main meal and 36,000 lipase units per snack.
• The mean change in CFA from the run-in period to the end of the double-blind period was 32% in the CREON group and 9% in the placebo group. However, the label does not provide information on the management of acute pancreatitis.

From the Research

Management Approach for Acute Pancreatitis

• The management of acute pancreatitis has undergone significant changes in recent years, with a focus on avoiding total parenteral nutrition and prophylactic antibiotics, as well as overly aggressive fluid resuscitation 3.
• Goal-directed moderate fluid resuscitation is now preferred over more aggressive strategies, and antibiotics should only be administered when there is a proven or highly probable infection 4.
• Urgent endoscopic retrograde cholangiopancreatography is beneficial for patients with acute cholangitis, and same-admission cholecystectomy for mild biliary pancreatitis is safe and efficient 4.
• The use of lactated Ringer's solution for fluid resuscitation has been shown to reduce systemic inflammation compared to normal saline 5.

Management Approach for Chronic Pancreatitis

• While the provided studies primarily focus on acute pancreatitis, it is noted that there is an increasing recognition of the risk of recurrence of acute pancreatitis and progression to chronic pancreatitis 3.
• However, there is limited information available in the provided studies on the specific management approach for chronic pancreatitis.

General Recommendations

• The management of acute pancreatitis should be based on evidence-based recommendations, taking into account the severity of the disease and the presence of complications 6.
• Ongoing research is essential for further advancements in the management of acute pancreatitis, including the development of novel pharmacologic treatments and strategies 4, 7.
• A personalized approach to management is crucial, with a focus on optimizing supportive treatment, including fluid resuscitation, pain management, and nutritional management 7.
