The tissue removed during a pancreaticoduodenectomy Whipple surgery. 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.
In total pancreatectomy, the gallbladder, distal stomach, a portion of the small intestine, associated lymph nodes and in certain cases the spleen are removed in addition to the entire pancreas. [1] In recent years, the TP-IAT (Total Pancreatectomy with Islet Autotransplantation [ 2 ] [ 3 ] ) has also gained respectable traction within the ...
The ductal pancreas network originates from the central pancreatic duct—this main duct with the bile duct opens into the duodenum. The ductal cells of the main pancreatic duct are bound by connective tissue and produce a columnar epithelium. [3] Interlobular ducts originate from the main pancreatic duct and connect the various pancreatic lobes.
The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth to the anus, as well as the associated glands, chemicals, hormones, and enzymes that assist in digestion.
Pancreatic cancer is the fifth most-common cause of cancer-related deaths in the United States, [8] and the seventh most-common in Europe. [9] In 2008, globally there were 280,000 new cases of pancreatic cancer reported and 265,000 deaths. [10] These cancers are classified as endocrine or nonendocrine tumors. The most common is ductal ...
In medicine, desmoplasia is the growth of fibrous connective tissue. [1] It is also called a desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, [1] or scar tissue within the abdomen after abdominal surgery. [1]
A pancreatic tumor is an abnormal growth in the pancreas. [1] In adults, almost 90% are pancreatic cancer and a few are benign. [1] Pancreatic tumors are rare in children. [1] Classification is based on cellular differentiation (ductal, acinar, neuroendocrine, other) and gross appearance (intraductal, cystic, solid). [1]
The pancreatic duct is generally regarded as abnormally enlarged if being over 3 mm in the head and 2 mm in the body or tail on CT scan. [9] Pancreatic duct or parts of pancreatic duct can be demonstrated on ultrasound in 75 to 85% of people. [10] Pancreatic ductal carcinoma is a common form of pancreatic cancer.
