Key points
- The two commonest causes of acute pancreatitis are gallstones and alcohol.
- About four in five acute attacks are mild; severe attacks with organ failure need intensive care.
- Infected necrosis is treated with a step-up approach — antibiotics, then drainage, then minimally invasive removal of dead tissue — rather than early open surgery.
- After gallstone pancreatitis, the gallbladder should be removed, usually during the same admission for mild attacks.
- In chronic pancreatitis with severe pain and a dilated duct, surgery such as a Frey procedure can give lasting relief.
When to go to hospital
Go to hospital immediately if you have:
sudden severe pain in the upper abdomen spreading to the back, especially with repeated vomiting; pain with fever, yellow eyes, breathlessness, low urine output, fast heartbeat or confusion; or known pancreatitis that suddenly worsens with fever. Acute pancreatitis needs hospital assessment, and severe attacks can threaten life.
Acute versus chronic pancreatitis
| Acute pancreatitis | Chronic pancreatitis | |
|---|---|---|
| What happens | A sudden attack of inflammation; the pancreas usually recovers | Ongoing scarring and loss of gland tissue over years |
| Common causes | Gallstones, alcohol; also high triglycerides, high calcium, after ERCP, some medicines | Alcohol, smoking, tropical (idiopathic) calcific pancreatitis, genetic causes, repeated acute attacks |
| Main symptoms | Severe upper abdominal pain radiating to the back, vomiting | Recurrent or constant pain, oily stools, weight loss, diabetes |
| Diagnosis | Typical pain plus raised lipase/amylase and/or scan findings | CT or MRI showing calcification, duct changes, atrophy |
Tropical calcific pancreatitis deserves special mention: a form of chronic pancreatitis seen in India and other tropical countries, often starting in childhood or young adulthood in people who do not drink, with large stones in the pancreatic duct and early diabetes. It is linked to genetic variants in some patients, and it carries an increased long-term risk of pancreatic cancer.
How severe is an acute attack?
- Mild: no organ failure and no local complications. Most patients improve within a few days with fluids, pain relief and early eating.
- Moderately severe: organ failure that settles within 48 hours, or local complications such as fluid collections.
- Severe: organ failure (kidneys, lungs, circulation) lasting more than 48 hours. These patients need intensive care, and this group carries most of the risk of death.
A contrast CT is not needed for every patient on day one. It is most useful after 72 hours, or earlier if the diagnosis is uncertain, to show whether part of the pancreas has died (necrosis). Early treatment focuses on careful intravenous fluids, pain control, oxygen, and feeding by mouth or tube as soon as possible, which protects the gut. Antibiotics are not given routinely unless infection is suspected.
Necrosis and the step-up approach
In some severe attacks, part of the pancreas and surrounding fat dies. Sterile necrosis often resolves on its own. The danger is when it becomes infected, usually in the second to fourth week, causing fever and worsening illness. Evidence over the last two decades has shown that early open surgery for necrosis does more harm than good. The current approach is to wait, where possible, until the dead tissue becomes walled off (around four weeks), and to step up gradually:
- 1
Antibiotics and support
Some infected collections settle with antibiotics, nutrition and organ support alone.
- 2
Drainage
A drain placed through the skin by a radiologist, or a stent placed from the stomach using endoscopic ultrasound.
- 3
Minimally invasive necrosectomy
If drainage is not enough, dead tissue is removed endoscopically through the stomach, or through a small incision along the drain track (video-assisted retroperitoneal debridement).
- 4
Open surgery
Reserved for patients who do not improve with the steps above or who develop complications such as bowel perforation, bleeding or abdominal compartment syndrome.
When surgery is needed
Gallbladder removal after gallstone pancreatitis
The most common operation linked to pancreatitis. After a mild attack, laparoscopic cholecystectomy during the same admission prevents recurrence; after severe attacks it is deferred until the patient recovers. Without it, a significant proportion suffer another attack.
Infected necrosis
Managed with the step-up approach above; surgical necrosectomy is for the minority who need it.
Pseudocyst and walled-off collections
Many resolve on their own. Persistent collections that cause pain, block the stomach or become infected are usually drained endoscopically into the stomach; surgical drainage is used when endoscopy is unsuitable.
Chronic pancreatitis pain
When a dilated, stone-filled duct causes pain not controlled by medicines and endoscopic therapy, surgery drains the duct. The lateral pancreaticojejunostomy (Partington–Rochelle) opens the duct along its length and joins it to the intestine; the Frey procedure adds coring out of the inflamed pancreatic head. Earlier surgery tends to give better pain relief than repeated endoscopic procedures in suitable patients.
Suspected cancer or complications
An inflammatory mass in the pancreatic head that cannot be distinguished from cancer, or blockage of the bile duct or duodenum, may need a Whipple operation or bypass.
Living with chronic pancreatitis
- Stop alcohol and smoking completely — both drive progression and pain, and smoking raises cancer risk.
- Pancreatic enzyme capsules with meals for oily stools and weight loss; vitamin D and nutritional support.
- Diabetes monitoring; pancreatic diabetes often needs insulin and behaves differently from type 2 diabetes.
- Pain management with a structured plan, avoiding escalating opioid use.
- Regular review, with scans if pain pattern changes, weight falls unexpectedly or jaundice appears.

Frequently asked questions
Is pancreatitis curable?
Most acute attacks resolve completely, especially once the cause, such as gallstones or alcohol, is removed. Chronic pancreatitis is permanent damage, but pain, digestion and diabetes can usually be managed well.
Do I need surgery for pancreatitis?
Most people do not. Surgery is needed for gallbladder removal after gallstone pancreatitis, for a minority with infected necrosis or problematic pseudocysts, and for chronic pancreatitis with pain not controlled otherwise.
What is tropical pancreatitis?
Tropical calcific pancreatitis is a form of chronic pancreatitis seen in India and other tropical regions, often in young non-drinkers, with large duct stones and early diabetes. It needs long-term follow-up because of an increased cancer risk.
What is the Frey procedure?
An operation for chronic pancreatitis that opens the pancreatic duct along its length, clears stones, cores out the inflamed head of the pancreas and joins it to a loop of intestine to relieve pain.
Can pancreatitis come back?
Yes, if the cause remains. Removing the gallbladder after gallstone pancreatitis and stopping alcohol after alcohol-related pancreatitis greatly reduce the risk of further attacks.
Does a pancreatic pseudocyst always need drainage?
No. Many shrink on their own. Drainage is advised when a collection persists and causes pain, vomiting, infection or blockage.
