# What is a Pancreaticoduodenectomy? An Overview
A pancreaticoduodenectomy, commonly referred to as a ‘Whipple procedure’, is a major operation to remove some parts of the pancreas, part of the small intestine, the gallbladder, and the bile duct. It is a very complex surgery used to treat cancer or inflammation of the pancreas, and is typically used as a last resort when other methods of treatment fail.
The procedure takes its name from Allan Whipple, an American surgeon who first described the procedure in 1935. It is still used today, however new advancements in surgical equipment and technique have significantly improved the benefits and outcomes of the procedure.
## What Does a Pancreaticoduodenectomy Involve?
A pancreaticoduodenectomy is a multi-step surgical procedure that can take several hours. The patient is typically placed under general anaesthesia for the duration of the surgery. The steps involved in the procedure are as follows:
1. An incision is made in the abdomen and the abdomen is opened up.
2. The parts of the pancreas, gallbladder, bile duct, and small intestine to be removed are identified and separated from the surrounding organs.
3. The severed parts of the pancreas, gallbladder, and small intestine are removed.
4. The remaining parts of the organs are reconnected.
5. The abdominal incision is closed.
In some cases, the patient may also have a drain placed near the pancreas to facilitate drainage of fluid and reduce the risk of infection.
## What are the Benefits of a Pancreaticoduodenectomy?
A pancreaticoduodenectomy provides several potential benefits, including:
1. Relief from symptoms related to the condition being treated.
2. Improved quality of life for the patient.
3. Reduced risk of complications from the procedure.
4. Improved outcomes from treatment of the underlying condition.
## What are the Expected Results of a Pancreaticoduodenectomy?
The expected results of a pancreaticoduodenectomy vary depending on the underlying condition being treated. In general, the procedure has been found to be generally successful in achieving its goals for treating conditions of the pancreas, gallbladder, and bile duct.
In particular, the procedure is successful in treating tumors of the pancreas, gallbladder, and bile duct. Additionally, it can be used to remove gallstones and to treat various other conditions of the pancreas, gallbladder, and bile duct.
The procedure has relatively low rates of complications, with the most common being infection, internal bleeding, and leakage of bile. In general, the risks associated with the procedure are outweighed by the potential benefits.
## Complications
Although pancreaticoduodenectomy is generally considered a safe procedure, there are some risks associated with the surgery.
The most common complications are internal bleeding, infection, and leakage of bile.
Internal bleeding is the most serious complication of the procedure and occurs in approximately 2-4% of patients. Other complications, such as infection or leakage of bile, occur in approximately 1-4% of patients.
In rare cases, the procedure can result in more serious complications such as stroke, heart attack, and damage to the respiratory system.
## Recovery
The recovery time following a pancreaticoduodenectomy depends on the individual patient and the severity of the condition being treated. Generally, it can take 3-7 weeks for a patient to fully recover from the procedure, however the exact timeline will vary depending on the individual.
During the recovery period, patients can expect to experience some pain, nausea, and fatigue. Many patients report that their pain improves as the weeks progress.
To ensure a smooth recovery, it is important that the patient follows the instructions and advice of their doctor, including not engaging in any strenuous activity until they have fully recovered from the surgery.
## Final Thoughts
Pancreaticoduodenectomy is a major and complex surgical procedure used to treat cancer and various other conditions of the pancreas, gallbladder, and bile duct. It has a relatively low rate of post-operative complications, is generally successful in treating the underlying condition, and can provide relief from symptoms associated with the condition.
That being said, the procedure carries risks and should be considered a last resort, after all other treatment options have been exhausted. As with any major surgery, it is important to carefully weigh the potential benefits against the risks before proceeding with the procedure.

Definition & Overview
Pancreaticoduodenectomy is a surgical procedure for treating pancreatic cancer and involves removing several parts of the digestive system. More commonly termed Whipple surgery, it was pioneered and developed by surgeon Allen Oldfather Whipple to remove tumours in the head of the pancreas.
Depending on the location of tumour cells, the physician would recommend one of the two types of pancreaticoduodenectomy. The first is the conventional Whipple surgery, which removes the head of the pancreas and nearby lymph nodes, gallbladder, the uppermost part of the small intestine, and the pylorus. The other type, which is referred to as pylorus-sparing Whipple surgery, retains the pylorus.
Who Should Undergo & Expected Results
The procedure was initially developed to treat several malignant conditions of the pancreas, which include:
- Pancreatic ductal adenocarcinoma
- Pancreatic islet cell carcinoma
- Ampullary carcinoma
- Cholangiocarcinoma
- Duodenal carcinoma
It is important to note that this procedure is only recommended if malignant cells have not spread to other parts of the pancreas and the disease has not advanced to nearby blood vessels like the artery and the superior mesenteric vein.
Whipple surgery may also be a treatment option for some benign diseases, such as benign periampullary neoplasms in which the surgeon would be unable to perform a resection of the ampulla and those with duodenal neoplasms. In rare cases, the procedure is also performed when parts of the pancreas have been damaged due to trauma.
Pancreaticoduodenectomy can be performed in young and older patients, who are then advised to undergo chemotherapy radiation after surgery. In some cases, the connection between the small intestine and the pancreas breaks down after surgery and would require emergency care.
Studies have indicated that patients experience near-normal quality of life after a successful Whipple surgery. Hospitalisation is required for several weeks to monitor patient condition depending on several factors like age and extent of disease. Patients would expect weight loss and pancreatic insufficiency as common outcomes of this procedure.
How Does the Procedure Work?
Pancreaticoduodenectomy usually takes five to eight hours and starts with sedating the patient. The surgeon then makes one large incision in the abdominal area. Since several parts of the digestive system are affected, the procedure progresses in several stages or sections and major blood vessels are located and carefully evaluated. Care and precision are crucial to segregate and protect unaffected vessels. Those that need to be cut off are carefully ligated to prevent internal bleeding. The head of the pancreas, the gallbladder, the uppermost part of the small intestine, and the surrounding lymph nodes are then located and removed in stages. For the conventional Whipple procedure, the pylorus is removed as well. The remaining parts of the pancreas are then reconnected to the remaining bile duct and small intestine. If necessary, abdominal drains are used to prevent pancreatic leak. Sutures are then used to close the abdomen.
Possible Complications and Risks
Classified as a major surgical procedure, pancreaticoduodenectomy is linked to the following risks and complications:
- Delayed gastric emptying that might require intravenous feeding
- Gastroduodenal artery complications such as bleeding from abdominal drains and gastrointestinal bleeding
- Accumulation of pancreatic fluid
- Formation of pancreatic fistula
- Bacterial infection of the wound or in the blood
Compromised functions of the digestive system, such as bowel movement and the production of digestive enzymes. Other bodily functions might also be affected, as respiratory and renal failure can occur. There is a small possibility of multisystem organ failure and even death. As the digestive organs are regaining their functions, diarrhea is a common occurrence.
There are also several long-term associated risks such as the development of pancreatic insufficiency, as well recurring pancreatitis and chronic pancreatic pain, which may necessitate the long-term intake of pain medications. The pancreas also produce insulin and removing some part of it might lead to the development of diabetes, especially for people who have abnormal blood levels long before surgery.
