Undergoing a distal pancreatectomy and splenectomy is a significant event. This article provides a structured guide to understanding the dietary adjustments and recovery process following this surgery. The information aims to support patients and their families through this journey, addressing concerns and offering practical advice.
Understanding the Procedure
The pancreas, a vital part of the digestive system, is located at the back of the upper abdomen, in front of the spine and behind the stomach. It plays a crucial role in producing enzymes that digest food and hormones like insulin and glucagon that regulate blood sugar levels. A distal pancreatectomy involves the surgeon removing the left half (body & tail) of the pancreas, which is furthest away from the duodenum (the first part of the small bowel), leaving the head intact. The spleen, located next to the pancreas, may also be removed during this procedure if the tumor involves blood vessels that carry blood to the spleen. The spleen makes white blood cells that help your body fight infections. Your spleen also filters your blood, stores blood cells, and destroys old blood cells.
This surgery might be performed laparoscopically (keyhole surgery) or through a more extensive open surgery, depending on the complexity of the case.
Pre-Operative Preparation
Preparing for surgery involves optimizing your physical health. Regular exercise and a nutritious diet are essential. If maintaining this is difficult, seeking advice from a doctor or specialist nurse is recommended. Routine tests will be conducted to ensure you are fit for the operation, and you will be involved in planning your care and recovery. It is important to inform the medical team about your individual needs, circumstances, general health, past operations, illnesses, allergies, and medications.
Certain medications, especially blood-thinning medications like aspirin, clopidogrel, or warfarin, may need to be stopped before surgery to reduce risks. A consent form will be signed after you fully understand the operation. You will need to stop eating and drinking several hours before your operation. Elasticated stockings will be provided to prevent blood clots.

Immediate Post-Operative Care
After the operation, you will be monitored closely, possibly in the High Dependency Unit (HDU). Intravenous fluids will ensure adequate hydration until you can drink again. A naso-gastric (NG) tube may be inserted to drain stomach contents, preventing sickness. You may also have a naso-jejunal (NJ) feeding tube for liquid nutrition. Oxygen therapy will be provided, and nursing staff will guide you through deep breathing exercises. A surgical drain may be placed to remove fluid from the surgical area, and a catheter will drain urine. Pain management is typically administered through a patient-controlled analgesia system (PCAS) or oral medication. Wound healing will be monitored, with stitches or staples removed around 10-14 days post-operation.
Potential Post-Operative Complications
While most patients recover well, complications can occur. Preventative measures are in place to reduce these risks.
Bleeding: Some bleeding is expected during surgery, and occasionally a blood transfusion is needed.
Infection: Infections such as wound, chest, or urine infections may develop. Wound infections may require the wound to be opened to drain pus.
Digestive Juice Leak: A leak can occur where the pancreas was divided, potentially delaying recovery. It is usually treated by draining the fluid.

Ileus: The bowel may temporarily "go to sleep," requiring a nasogastric tube.
Diabetes: The remaining pancreas may not produce enough insulin, requiring regular blood sugar monitoring and potential treatment.
Pancreatic Insufficiency: Some patients may require replacement pancreatic enzymes to digest food, which will be explained by doctors, nurses, and dietitians.
Change in Bowel Habit: Changes in bowel habits may necessitate dietary adjustments and smaller, more frequent meals.
Dietary Guidelines Post-Surgery
Dietary adjustments are crucial for recovery. The goal is to support healing, manage potential complications, and maintain nutritional status.

Initial Dietary Progression
Clear Liquids: Initially, you will be allowed sips of water, gradually increasing until you can drink freely.
Light Diet: A light diet will be introduced, and you will be encouraged to eat small portions.
General Dietary Recommendations
Eat Smaller, More Frequent Meals: Aim for 5-6 small meals a day to ease digestion.
Focus on Protein: Include a protein source in each meal to aid healing. Good sources include lean meat, fish, eggs, dairy products, beans, and nuts. Protein shakes or smoothies can also be helpful.
Stay Hydrated: Drink 6-8 cups (48-64 ounces) of fluid daily, taking small sips to avoid feeling full.
Eat Slowly and Chew Food Well: This aids digestion and prevents overeating.
Limit Fat Intake: High-fat foods can cause discomfort.
Avoid Concentrated Refined/Simple Carbohydrates: If symptoms of glucose intolerance or dumping are present, avoid sugary foods.
Consider Vitamin Supplements: Discuss with your doctor or dietitian the use of a multivitamin or individual vitamin supplements, especially calcium and fat-soluble vitamins A, D, E, and K if malabsorption-induced diarrhea is present.
Medications: Take pancreatic enzymes just before eating to aid digestion.
Managing Specific Symptoms
Early Satiety: Add high-calorie and high-protein foods to meals.
Delayed Stomach Emptying: Consume liquids with calories and protein, such as milk, diluted juice, oral nutrition supplements, shakes, and smoothies.
Dumping Syndrome: Avoid foods high in sugar.
Lactose Intolerance: Limit or avoid dairy products if intolerance develops.
Diarrhea: May need anti-diarrheal agents.
Food Diary
Keeping a daily journal of your diet, weight, enzyme usage, bowel movements, and blood glucose readings can help identify problem foods and adjust your diet accordingly.
Addressing Nutritional Challenges
Pancreatic cancer and pancreatectomy can lead to significant nutritional challenges, including cachexia (muscle wasting), malnutrition, and weight loss. These issues can stem from symptoms like vomiting, abdominal pain, anorexia, and malabsorption.
Nutritional Status Assessment
Assessing your nutritional status before and after diagnosis is critical. Cachexia is common in pancreatic cancer patients, marked by low levels of protein, albumin, and hemoglobin. Rapid weight loss, especially exceeding 10%, can indicate an aggressive condition.
Anorexia Management
Anorexia, or loss of appetite, is a common symptom. Treatment may include appetite stimulants, drugs targeting cachectic signaling molecules, and nutritional supplements. Central appetite stimulants like megestrol acetate and ghrelin can be beneficial.
Nutritional Support
Nutritional intervention, either parenteral (intravenous) or enteral (tube feeding), is essential to maintain nutritional and functional status. Oral nutrition can reduce complications and improve quality of life. Enteral nutrition post-operatively can also reduce infective complications. Postoperative total parenteral nutrition is reserved for patients unable to feed orally or enterally.
Lifestyle Adjustments
Physical Activity
Engage in physical activity for at least 30 minutes per day. Regular movement aids recovery and helps prevent complications.
Wound Care
Keep your wound clean with daily showers. Numbness around the incision is normal and will fade over time.
Monitoring
You will need to maintain a daily log of your glucose levels at home which you will bring with you on your first follow up with your surgeon.
Long-Term Follow-Up
Regular check-ups at the hospital are essential to monitor your progress and address any concerns. Your first clinic appointment will be approximately four weeks after going home.
The Importance of Support
Recovery from a distal pancreatectomy and splenectomy is a gradual process. It's important to take plenty of rest during the early days and weeks at home. Increasing your level of activity as the weeks go by is important. Support from family, friends, and healthcare professionals plays a crucial role in your recovery. Leeds Cancer Support complements care provided by your clinical team and offers a variety of support services including complementary and supportive therapies.
