Pancreatic Cancer Surgery

Pancreatic cancer surgery is the operative management of pancreatic neoplasms, dominated by pancreatic ductal adenocarcinoma. Surgical resection - most often pancreaticoduodenectomy (the Whipple procedure) for tumours of the pancreatic head - offers the only realistic prospect of long-term cure, but only a minority of patients have resectable disease at diagnosis, and the operation is technically demanding with significant morbidity.

Definition

Pancreatic cancer surgery refers to operative resection of pancreatic malignancy - principally pancreaticoduodenectomy for head tumours and distal pancreatectomy for body and tail tumours - undertaken with curative intent in patients with anatomically and biologically resectable disease.

Scope

This topic covers the surgical perspective on pancreatic cancer: the dominant histology and its aggressive behaviour, the concept of resectability, the principal resections and their characteristic complications, and the role of multidisciplinary treatment. It is a reference description and is not individualized clinical advice.

Key concepts

• Pancreatic ductal adenocarcinoma
• Resectable, borderline resectable, and unresectable disease
• Pancreaticoduodenectomy (Whipple procedure)
• Distal pancreatectomy
• Postoperative pancreatic fistula
• Multidisciplinary and neoadjuvant treatment

Clinical relevance

Resectability - determined chiefly by the tumour's relationship to major mesenteric vessels and by the absence of metastases - governs whether surgery is considered, and only a minority of patients present with resectable disease. Pancreaticoduodenectomy and distal pancreatectomy are the principal operations, and postoperative pancreatic fistula is a defining complication that drives much of the operative morbidity. This entry describes the surgical landscape for reference and educational purposes and is not a basis for individual treatment decisions.

Epidemiology

Pancreatic ductal adenocarcinoma is among the most lethal common cancers, with overall survival remaining poor because most tumours are diagnosed at an advanced, unresectable stage; it is a leading cause of cancer death despite being less common than several other solid tumours.

Evidence & guidelines

Contemporary reviews frame pancreatic cancer as a disease requiring multidisciplinary management, increasingly incorporating neoadjuvant therapy for borderline resectable tumours. Randomized evidence has refined perioperative care - for example showing that routine preoperative biliary drainage before surgery for pancreatic-head cancer increased complications compared with early surgery, and evaluating pharmacologic strategies to reduce postoperative pancreatic fistula.

Debates

Routine preoperative biliary drainage before pancreatic-head resection

A randomized trial found that routine preoperative biliary drainage in patients with obstructive jaundice from pancreatic-head cancer was associated with more serious complications than proceeding to early surgery, prompting a more selective use of drainage.

Reducing postoperative pancreatic fistula

Pancreatic fistula is a major source of morbidity after pancreatic resection; trials such as the pasireotide study have tested pharmacologic prophylaxis, illustrating ongoing efforts to lower this complication.

Frequently asked questions

What is the Whipple procedure?

The Whipple procedure (pancreaticoduodenectomy) is the standard resection for cancers of the pancreatic head, removing the head of the pancreas together with the duodenum and adjacent structures and reconstructing the gastrointestinal and biliary tract.

Why can only some pancreatic cancers be operated on?

Surgery with curative intent requires the tumour to be resectable - confined enough relative to major blood vessels and without metastases - but most pancreatic cancers are diagnosed at an advanced stage, so only a minority of patients are candidates for resection.
