Surgery offers the best chance for a cure and long-term management of pancreatic cancer. However not every patient is eligible for surgical intervention. Factors such as the stage of the disease, personal health, and the ability to tolerate a major operation—including prolonged anesthesia—all must be considered.
Pancreatic cancers are divided into four surgical categories.
- Resectable This type of cancer can be surgically removed. These tumors may lie within the pancreas or extend to nearby organs, but do not involve local blood vessels. When cancer is resectable, there is no evidence of any spread outside the tissue removed during surgery.
- Borderline Resectable This type of cancer is also limited to the pancreas but may be close to major blood vessels in the pancreas. Often these tumors can be removed and the vein can be reconstructed but the surgical procedures are more complicated.
- Locally Advanced This type of cancer cannot be surgically removed with traditional methods because it has invaded nearby blood vessels or nearby organs. However, there is no evidence of spread to distant parts of the body.
- Metastatic This type of cancer cannot be surgically removed because the cancer has spread to other parts of the body.
While there have been significant improvements in pancreatic operations, surgical procedures remain complex and can be difficult for some patients to undergo. It is thus important to choose an experienced surgeon and a facility that has performed a very high number of pancreatic operations, often referred to as a “high-volume” center.
Studies have shown that patients who undergo pancreatic surgery at a high-volume center experience fewer operative complications and better outcomes.
At the Pancreas Center our commitment to our patients and our time-tested surgical expertise has led to high success rates. Our surgeons perform specialized operations to remove cancerous tissue while preserving as much healthy tissue as possible.
Pancreaticoduodenectomy, often referred to as the Whipple procedure, is the most common operation to treat tumors located in the head of the pancreas where about 75 percent of pancreatic cancers occur. This famous procedure was developed in our own Department of Surgery by Dr. Allen O. Whipple, the former Chair of Surgery, in 1935.
There are two types of Whipple procedures—the conventional Whipple and the pylorus-sparing Whipple. The conventional Whipple involves removal of the head of the pancreas, the duodenum, and a portion of the stomach, as well as the gallbladder and a portion of the bile duct. The remaining stomach, bile duct and pancreas are then reconnected to the digestive tract to restore flow of food that’s been ingested along with digestive enzymes and bile. In a pylorus-sparing Whipple, a section of stomach is not removed during the operation.
A Whipple procedure typically requires 4 to 6 hours depending on the exact location and pathology of the tumor.
Distal Pancreatectomy removes the tail and body of the pancreas while preserving the head of the pancreas. Since the spleen is so close to the tail of the pancreas, sometimes the spleen is also removed during the procedure. A distal pancreatectomy can sometimes be performed laparoscopically resulting in shorter hospital stays, less blood loss, and fewer complication rates.
A typical distal pancreatectomy procedure requires about 2 to 4 hours, depending on the exact location and pathology of the tumor.
Central Pancreatectomy removes a tumor in the neck or body of the pancreas while preserving the healthy head and tail of the pancreas. This highly specialized procedure is performed at only a handful of centers in the United States, including The Pancreas Center at New York-Presbyterian/Columbia University Medical Center. A central pancreatectomy leaves exocrine and endocrine functions intact and usually decreases the patient’s chance of developing insulin-dependent diabetes.
A typical central pancreatectomy procedure requires between 2 and 4 hours, depending on the exact location and pathology of the tumor.
Total Pancreatectomy removes the entire pancreas and is similar to a Whipple procedure, in that a portion of the stomach, duodenum, gallbladder, and local lymph nodes are also removed. The spleen may be removed as well. This procedure was developed to deal with malignant cells that have invaded most of the pancreatic tissue. Because the entire pancreas is removed, however, the patient becomes an insulin-dependent diabetic for life. For this reason, the procedure is not used when a more limited pancreatectomy is possible. Total pancreatectomy typically requires 5 to 7 hours.
Surgery for neuroendocrine tumors is often less extensive than the surgery for adenocarcinoma but this depends on the location of the tumor.
