A pancreaticoduodenectomy, pancreatoduodenectomy[1], Whipple procedure, or Kausch-Whipple procedure, is a major surgical operation involving the pancreas, duodenum, and other organs. This operation is performed to treat cancerous tumours on the head of the pancreas or cancerous tumors on ducts or vessels near the pancreas. The procedure is now being performed using the Da Vinci surgical robotic system, making it much less invasive and risky because only three small incisions, or access points, are needed. This is still, nevertheless, a major surgical procedure.

[edit] History

This procedure was originally described by Alessandro Codivilla in 1898 and Walther Kausch in 1912, and later perfected by Allen Oldfather Whipple in the 1930s.[2]

This technique is often called the Whipple procedure since it was named after American surgeon Dr. Allen Whipple who devised the procedure in 1935 and subsequently came up with multiple refinements to his technique (surgeons in training are often quizzed on the refinement he made that provided the most improvement in outcomes to that date: the use of non-absorbable silk over absorbable catgut suture).[citation needed] The first resection for a periampullary cancer was performed by the German surgeon Kausch in 1909.

[edit] Anatomy involving the procedure

The basic concept behind the pancreaticoduodenectomy is that the head of the pancreas and the duodenum share the same arterial blood supply. These arteries run through the head of the pancreas, so that both organs must be removed. If only the head of the pancreas was removed it would compromise blood flow to the duodenum.

The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach; the first and second portions of the duodenum; the head of the pancreas; the common bile duct; and the gallbladder.

[edit] Pancreaticoduodenectomy in modern medicine

The Whipple procedure today is very similar to Whipple's original procedure. It consists of removal of the distal half of the stomach (antrectomy), the gall bladder (cholecystectomy), the distal portion of the common bile duct (choledochectomy), the head of the pancreas, duodenum, proximal jejunum, and regional lymph nodes. Reconstruction consists of attaching the pancreas to the jejunum (pancreaticojejunostomy) and attaching the common bile duct to the jejunum (choledochojejunostomy) to allow digestive juices and bile to flow into the gastrointestinal tract and attaching the stomach to the jejunum (gastrojejunostomy) to allow food to pass through.

Originally performed in a two-step process, Whipple refined his technique in 1940 into a one-step operation. Using modern operating techniques, mortality from a Whipple procedure is around 5% nationwide (<2% in high volume academic centers).[3]

[edit] Pancreaticoduodenectomy versus total pancreatectomy

Some authors advocate the removal of the whole pancreas (total pancreatectomy) instead of just the head.[citation needed] However, clinical trials have failed to demonstrate significant survival benefits, mostly because patients who submit to this operation tend to develop a particularly severe form of diabetes (so-called brittle diabetes).

[edit] Pylorus-sparing pancreaticoduodenectomy

More recently, the pylorus-sparing pancreaticoduodenectomy (a.k.a. Traverso-Longmire procedure / PPPD) is growing increasingly popular, especially among European surgeons. The main advantage of this technique is that the pylorus, and thus normal gastric emptying, is preserved.[4] However, some doubts remain on whether it is an adequate operation from an oncological point of view. In practice, it shows similar long-term survival as a Whipple's (pancreaticoduodenectomy + hemigastrectomy), but patients benefit from improved recovery of weight after a PPPD, so this should be performed when the tumour does not involve the stomach and the lymph nodes along the gastric curvatures are not enlarged.[5]

Another controversial point is whether patients benefit from retroperitoneal lymphadenectomy.

[edit] Morbidity and mortality

Pancreaticoduodenectomy is considered, by any standard, a major surgical procedure. In some hospitals, it carries a terrible reputation for high rates of morbidity . Mortality rates are improved in high-volume hospitals, however this procedure still carries a significant degree of risk (~10%).[6]

[edit] In popular culture

The early 1970's medical drama television series "Medical Center" had an episode in which Dr Gannon performed a full Whipple's procedure on a young lady, unsuccessfully- as she died of complications shortly thereafter. It was one of the very few of Dr Gannon's fictitious patients to ever die under his knife.

There is an episode of the comedy television series Scrubs where the intern surgeon Turk is upset because he didn't get assigned a Whipple procedure and shouts, "What's a brother gotta do to get a Whipple around here?!"

There is an episode of Grey's Anatomy, where intern surgeon Christina Yang is trying to get a Whipple procedure- Season 1 Episode 4.

The musician Chris Rea underwent a Whipple procedure in 2001, this near brush with death being the catalyst for a complete change in musical direction and motivation. The resulting Blue Guitars 11 CD collection of 137 blues inspired tracks recorded in just 18 months, completed with his own paintings as album covers, is seen by himself as his finest work to date.

Steve Jobs had a Whipple procedure 9 months after being diagnosed with a rare operable pancreatic tumor.
