Puestow Procedure: Indications, Surgery, Recovery & Risks
The Puestow procedure is a surgical treatment performed for selected people with chronic pancreatitis who have a widened (dilated) pancreatic duct and ongoing symptoms despite medical management. The operation is designed to improve drainage of pancreatic secretions by creating a connection between the pancreatic duct and the small intestine.
Chronic pancreatitis is a long-term inflammatory condition that gradually damages the pancreas. Over time, inflammation may lead to narrowing of the pancreatic duct, stone formation, and increased pressure within the duct. These changes are associated with persistent abdominal pain, digestive problems, and reduced pancreatic function in some individuals.
The Puestow procedure is one of several surgical options used in carefully selected patients. Whether it is appropriate depends on factors such as pancreatic duct size, imaging findings, the underlying cause of chronic pancreatitis, and the person’s overall health.
This guide explains the Puestow procedure, including why it is performed, who may benefit from it, how the surgery is carried out, possible risks, recovery, and frequently asked questions.
What Is the Puestow Procedure?
The Puestow procedure, also known as longitudinal pancreaticojejunostomy, is a pancreas-preserving surgical procedure used to improve drainage from the pancreatic duct.
Instead of removing the pancreas, the surgeon opens the length of the enlarged pancreatic duct and joins it to a loop of the small intestine (jejunum). This allows pancreatic secretions to drain more freely.
The procedure was developed to address pain and ductal obstruction associated with chronic pancreatitis in selected patients.
Unlike operations performed for pancreatic cancer, the Puestow procedure focuses on improving drainage while preserving as much pancreatic tissue as possible.
Why Is the Puestow Procedure Performed?
The Puestow procedure is primarily performed for selected patients with chronic pancreatitis and a dilated pancreatic duct.
Long-standing inflammation may result in:
- Pancreatic duct obstruction
- Pancreatic duct stones
- Increased pressure inside the duct
- Persistent upper abdominal pain
- Digestive symptoms related to chronic pancreatitis
The aim of surgery is to improve drainage of the pancreatic duct when appropriate based on clinical evaluation and imaging findings.
Conditions Associated With the Puestow Procedure
The operation may be considered in people with:
- Chronic pancreatitis
- Dilated main pancreatic duct
- Pancreatic duct stones
- Ductal narrowing (strictures)
- Persistent symptoms despite medical treatment
- Recurrent episodes related to chronic pancreatic duct obstruction
Not every person with chronic pancreatitis requires surgery. The treatment approach depends on symptoms, imaging findings, pancreatic function, and response to non-surgical management.
Who May Be a Candidate for the Puestow Procedure?
Doctors evaluate several factors before recommending the Puestow procedure.
A patient may be considered for surgery after a detailed assessment that includes symptoms, imaging studies, and overall health.
Factors that support consideration of the procedure include:
- A significantly dilated main pancreatic duct
- Chronic pancreatitis confirmed through imaging
- Persistent pain despite medical management
- Pancreatic duct stones causing obstruction
- Adequate fitness for surgery
Every treatment plan is individualized, and a multidisciplinary team may be involved in decision-making.
Who May Not Be a Suitable Candidate?
The Puestow procedure is not appropriate for every patient with pancreatic disease.
Alternative treatments may be considered when there is:
- A small pancreatic duct
- Suspicion or diagnosis of pancreatic cancer
- Acute pancreatitis requiring different management
- Severe medical conditions that increase surgical risk
- Extensive disease requiring another type of pancreatic operation
A pancreatic surgeon determines the most appropriate treatment after reviewing imaging studies and clinical findings.
How Do Doctors Evaluate Patients Before Surgery?
Before recommending the Puestow procedure, doctors perform a detailed evaluation to understand the extent of pancreatic disease.
This assessment usually includes:
Medical History
The healthcare team reviews:
Duration of symptoms
Previous episodes of pancreatitis
Current medications
Alcohol history, where relevant
Smoking history
Previous abdominal surgery
Family history of pancreatic disease
Physical Examination
The examination focuses on identifying signs related to chronic pancreatitis, nutritional status, and abdominal tenderness.
Blood Tests
Blood investigations may include:
Complete blood count
Liver function tests
Kidney function tests
Blood sugar levels
Pancreatic enzyme levels when appropriate
Coagulation profile before surgery
These tests help assess overall health and assist with surgical planning.
Imaging Studies
Imaging plays a central role in deciding whether the Puestow procedure is suitable.
Investigations may include:
CT Scan
A CT scan provides detailed information about:
Pancreatic calcification
Pancreatic duct size
Pancreatic stones
Surrounding organs
Complications of chronic pancreatitis
MRI and MRCP
Magnetic Resonance Cholangiopancreatography (MRCP) provides detailed images of the pancreatic and bile ducts without using invasive techniques.
It helps identify:
Duct narrowing
Stone location
Ductal anatomy
Obstruction
Endoscopic Ultrasound (EUS)
Endoscopic ultrasound offers detailed images of the pancreas and surrounding structures.
In selected patients, it helps evaluate chronic pancreatitis and exclude other pancreatic conditions.
Is the Puestow Procedure a Major Surgery?
Yes.
The Puestow procedure is considered a major abdominal operation because it involves surgery on the pancreas and the small intestine under general anesthesia.
As with any major surgery, careful preoperative assessment, postoperative monitoring, and follow-up are important parts of treatment.

Benefits of the Puestow Procedure
The Puestow procedure is designed to improve drainage of the pancreatic duct in carefully selected patients with chronic pancreatitis. The expected benefits vary depending on the extent of pancreatic disease, the individual’s overall health, and other medical conditions.
Potential benefits include:
- Improved drainage of pancreatic secretions
- Relief of pancreatic duct obstruction
- Management of symptoms associated with chronic pancreatitis
- Removal of pancreatic duct stones during surgery when present
- Preservation of much of the pancreatic tissue compared with some pancreatic resection procedures
The treatment plan and expected outcomes should always be discussed with the treating surgeon before surgery.
Risks of the Puestow Procedure
Like all major abdominal operations, the Puestow procedure carries potential risks.
Possible complications include:
- Bleeding
- Infection
- Leakage from the surgical connection (anastomotic leak)
- Pancreatic fistula
- Delayed gastric emptying
- Blood clots
- Pneumonia
- Injury to nearby organs
- Wound-related complications
