Whipple procedure
Formal Definition
Pancreaticoduodenectomy — a complex surgical resection for periampullary malignancies (pancreatic head adenocarcinoma, distal cholangiocarcinoma, ampullary carcinoma, duodenal carcinoma) involving en bloc removal of the pancreatic head, duodenum, distal common bile duct, and gallbladder, followed by reconstruction with pancreaticojejunostomy, hepaticojejunostomy, and gastrojejunostomy; a high-risk procedure with significant morbidity (pancreatic fistula, delayed gastric emptying, bile leak) requiring high-volume centers for optimal outcomes.
How It's Used on the Ward
"Whipple" or "pancreaticoduodenectomy" — the big surgery for pancreatic head cancer; it involves removing the head of the pancreas, the duodenum (first part of the small intestine), part of the bile duct, and the gallbladder, then reconnecting everything back together; it is a major operation with a significant risk of complications, so the surgeon needs to be experienced and the patient needs to be fit enough.
Example
""67-year-old with pancreatic head mass, CA19-9 890, biopsy-confirmed pancreatic ductal adenocarcinoma, resectable on CT staging (noSMA/vascular involvement, no metastases). Performance status ECOG 0, BMI 26. Operative plan: classic Whipple procedure. Resection phase: pancreatic head, duodenum, distal common bile duct, gallbladder removed en bloc with margins. Reconstruction phase: pancreaticojejunostomy (pancreas to jejunum), hepaticojejunostomy (bile duct to jejunum), gastrojejunostomy (stomach to jejunum). Estimated blood loss 400mL. Pathology: T3N1M0, R0 (margins negative). ICU for 48h post-op. JP drains placed. Pancreatic fistula rate in high-volume center: ~10%.""
Clinical Context
Indications: resectable pancreatic head adenocarcinoma, distal cholangiocarcinoma, ampullary carcinoma, duodenal carcinoma, IPMN with high-grade dysplasia. Pre-op workup: CT pancreas protocol (arterial phase for vascular involvement), MRI/MRCP, EUS + FNA, CA19-9 (not diagnostic but baseline + prognostic), laparoscopic staging (detect occult metastases), nutritional optimization, biliary drainage if jaundice severe (ERCP with metal stent). Types: classical Whipple (distal gastrectomy) vs pylorus-preserving Whipple (no gastrectomy — similar outcomes, may have better nutritional status). Post-op complications: pancreatic fistula (POPF grade A/B/C, most serious — treated with drain management, octreotide, TPN; grade C needs intervention), delayed gastric emptying, bile leak, chyle leak, wound infection. Node positivity reduces survival. Adjuvant chemotherapy (gemcitabine or FOLFIRINOX) improves survival in resected patients. Volume matters: >20 cases/year = lower mortality.
