What is the appropriate management of chronic pancreatitis with pancreatic duct dilatation?

From the Guidelines

The appropriate management of chronic pancreatitis with pancreatic duct ectasia is longitudinal pancreaticojejunostomy (option c). This surgical procedure, also known as the Puestow procedure, is the preferred approach when dealing with a dilated main pancreatic duct in chronic pancreatitis, as it effectively decompresses the dilated pancreatic duct system, allowing pancreatic secretions to drain freely into the jejunum, which helps alleviate the pain associated with ductal hypertension 1. The procedure involves opening the pancreatic duct longitudinally and creating a side-to-side anastomosis with a Roux-en-Y jejunal limb.

Longitudinal pancreaticojejunostomy preserves pancreatic tissue and function while addressing the underlying pathophysiology of obstructed pancreatic drainage. It is preferred over more extensive resections like pancreaticoduodenectomy or near-total pancreatectomy because it maintains pancreatic endocrine and exocrine function while still effectively treating the ductal dilation. Distal pancreaticojejunostomy would not address dilation of the entire duct system, and sphincteroplasty alone is insufficient for managing diffuse ductal changes seen in chronic pancreatitis with duct ectasia. According to recent guidelines, surgical intervention should be considered over endoscopic therapy for long-term treatment of patients with painful obstructive chronic pancreatitis 1.

Some key points to consider when deciding on the appropriate management of chronic pancreatitis with pancreatic duct ectasia include:

• The need to preserve pancreatic tissue and function
• The importance of addressing the underlying pathophysiology of obstructed pancreatic drainage
• The potential benefits and drawbacks of different surgical procedures, including longitudinal pancreaticojejunostomy, pancreaticoduodenectomy, and near-total pancreatectomy
• The role of endoscopic therapy in the management of chronic pancreatitis, and the potential benefits and limitations of this approach 1.

Appropriate Management of Chronic Pancreatitis with Pancreatic Duct Ectasia

The appropriate management of chronic pancreatitis with pancreatic duct ectasia involves several surgical options. The choice of procedure depends on various factors, including the size of the pancreatic duct, the presence of complications, and the patient's overall health.

• Surgical Options:
  • Pancreaticoduodenectomy (Whipple procedure) 2, 3, 4
  • Distal pancreatectomy 2, 5, 4
  • Longitudinal pancreaticojejunostomy (Puestow procedure) 2, 6, 3, 5, 4
  • Near total pancreatectomy 2
  • Sphincteroplasty 2

Indications for Each Procedure

• Pancreaticoduodenectomy: Indicated when the main pancreatic duct is not dilated, the pancreatic head is enlarged, or there is suspicion of malignancy 2, 4
• Longitudinal Pancreaticojejunostomy: Indicated when the pancreatic duct is dilated, and the patient has intractable pain 2, 6, 3, 5, 4
• Distal Pancreatectomy: Indicated when the disease is confined to the distal part of the gland 4
• Near Total Pancreatectomy: Indicated in some cases, but the specific indications are not well-defined 2
• Sphincteroplasty: Not a primary procedure for chronic pancreatitis, but may be performed in conjunction with other procedures 2

Outcomes and Complications

• Pain Relief: Longitudinal pancreaticojejunostomy and pancreaticoduodenectomy can provide significant pain relief 2, 6, 3, 5, 4
• Complications: Each procedure has its own set of potential complications, including intra-abdominal abscess, bleeding, and leakage of the pancreaticojejunostomy 3, 5
