Distal Pancreatectomy: Surgery of the Body and Tail
Distal pancreatectomy, performed for lesions of the body and tail, is a less extensive operation than surgery of the pancreatic head, and the digestive tract does not need reconstruction. Even so, leakage of secretions from the cut surface of the pancreas — a pancreatic fistula — remains its most common complication. The scope of the operation, whether the spleen is preserved and the pace of recovery all depend on the type and position of the lesion and on the patient's condition.

Distal pancreatectomy removes the body and tail of the pancreas. In malignant or high-risk lesions the spleen and the surrounding lymphatic tissue are commonly removed with it for oncological reasons. In benign or low-risk lesions in a suitable position, preserving the spleen may be considered. When the spleen is removed, a vaccination and infection-prevention plan is arranged by the doctor. Not every patient needs enzyme tablets or develops diabetes afterwards; the need depends on the function of the remaining pancreas and is monitored.
When is it performed?
- Resectable cancer of the pancreatic body or tail
- Cystic lesions and IPMN with high-risk features
- Mucinous cystic neoplasms
- Neuroendocrine tumours
- Some benign lesions causing symptoms or complications
- Selected cases of chronic pancreatitis and trauma
What happens during the operation?
The pancreas is divided at an appropriate level for the lesion and the body-and-tail portion is removed. The cut surface is closed with a stapler or sutures. In malignant disease the spleen, splenic vessels and surrounding lymphatic tissue are usually removed as well, because lymphatic drainage from this region follows the splenic vessels.
In benign or low-risk lesions, techniques preserving the splenic vessels or relying on the short gastric vessels may be used. Spleen preservation is not possible in every patient; proximity to the vessels and the findings during surgery are decisive.
| Situation | Approach | Note |
|---|---|---|
| Malignant lesion | Resection with spleen and lymphatic tissue | Oncological requirement |
| Benign / low-risk lesion | Spleen preservation may be considered | Depends on anatomy and position |
| Minimally invasive technique | Laparoscopic or robotic in selected cases | Team experience and lesion type |
| If the spleen is removed | Vaccination and infection plan | Arranged by the doctor |
What to bear in mind if the spleen is removed
The spleen contributes to immunity against encapsulated bacteria. After splenectomy the doctor arranges vaccination against pneumococcus, meningococcus and Haemophilus influenzae type b, together with a plan for early review if signs of infection appear. Fever and chills should prompt prompt medical assessment.
Risks and possible problems
A fistula is usually managed with drain monitoring and nutritional adjustment; some patients need interventional drainage. How often these problems occur varies with the patient and the lesion.
- Leakage from the cut surface of the pancreas (pancreatic fistula)
- Fluid collection and abscess in the abdomen
- Bleeding
- Susceptibility to infection and a raised platelet count after splenectomy
- Unstable blood glucose depending on the volume of tissue removed
- Absorption problems requiring enzyme support in some patients
Nutrition, enzymes and glucose after surgery
Eating usually returns close to normal within a short time after distal pancreatectomy. Enzyme support is planned only for patients with signs of malabsorption and is not needed by everyone. Whether diabetes develops depends on how much tissue was removed and on pancreatic function beforehand, so blood glucose is monitored regularly in the first months.
Enhanced recovery principles — early mobilisation, early feeding and effective pain control — are applied. Where the diagnosis is oncological, further treatment and follow-up are set by the multidisciplinary team according to the pathology report.
