Open cholecystectomy
Open cholecystectomy removes the gallbladder through an abdominal incision, usually a right subcostal one, to treat symptomatic gallstones; it was standard from the 1880s until the 1980s.
Open pancreaticoduodenectomy
Open pancreaticoduodenectomy, the Whipple procedure, is an operation through a laparotomy that removes the pancreatic head and duodenum, mainly to treat pancreatic head and periampullary tumors.
Pancreatectomy
A pancreatectomy is an operation that removes all or part of the pancreas, chiefly for tumors; forms include the Whipple procedure, distal pancreatectomy, and total pancreatectomy.
Pancreatic head resection
Pancreatic head resection is an operation removing the head of the pancreas, most often as the Whipple procedure, the main curative treatment for pancreatic head cancers.
Pancreatic resection
Pancreatic resection is surgery that removes part or all of the pancreas to treat tumors and other pancreatic disease, including the Whipple procedure for pancreatic head cancer.
Pancreaticogastrostomy
Pancreaticogastrostomy is a surgical reconstruction that joins the pancreatic remnant to the stomach after resection, restoring exocrine drainage; it is the main alternative to pancreaticojejunostomy after pancreaticoduodenectomy, reintroduced in 1967.
Pancreaticojejunostomy
Pancreaticojejunostomy is a surgical anastomosis joining the pancreatic duct to a loop of jejunum, performed to restore drainage after pancreaticoduodenectomy or to relieve pain in chronic pancreatitis.
Pancreatoduodenectomy
Pancreatoduodenectomy, commonly called the Whipple procedure, is a major abdominal operation removing the pancreatic head, duodenum, distal bile duct, and gallbladder, used mainly for pancreatic head cancer.
Pancreatojejunostomy
Pancreatojejunostomy is a surgical anastomosis joining the pancreatic duct or cut pancreas to the jejunum, performed to reconstruct after pancreatoduodenectomy or to drain a dilated duct in chronic pancreatitis.
Pancreatosplenectomy
Pancreatosplenectomy is the en-bloc removal of the distal pancreas and spleen, performed mainly for pancreatic body or tail adenocarcinoma; its modern radical form, RAMPS, was introduced in 2003.
Partial hepatectomy
A partial hepatectomy is an operation removing part of the liver while leaving enough healthy remnant tissue for function, used mainly for liver tumors and metastases.
Partial splenectomy
Partial splenectomy is an operation that removes only the diseased or damaged portion of the spleen while preserving immune function, treating splenic trauma, cysts, tumors, and hypersplenism.
Portal vein resection
Portal vein resection is the en-bloc removal of a portal vein or superior mesenteric vein segment during pancreatic surgery, followed by reconstruction to restore blood return.
Portosystemic shunt
A portosystemic shunt is a surgical or interventional connection between the portal and systemic venous circulations that lowers portal pressure, used mainly for variceal bleeding and ascites in portal hypertension.
Robotic cholecystectomy
Robotic cholecystectomy is the removal of the gallbladder using a robotic-assisted laparoscopic system, in which the surgeon operates from a console; it now accounts for about one-quarter of US cholecystectomies.
Robotic liver resection
Robotic liver resection is a minimally invasive operation in which a surgeon removes part of the liver while controlling instruments from a robotic console, such as the da Vinci.
Robotic pancreaticoduodenectomy
Robotic pancreaticoduodenectomy is a minimally invasive operation in which a surgeon uses a robotic platform to remove the pancreatic head and duodenum, first performed by P. C. Giulianotti in 2001.
Roux-en-Y hepaticojejunostomy
Roux-en-Y hepaticojejunostomy is a surgical reconstruction that drains bile by joining the hepatic duct to a defunctionalized Roux limb of jejunum, used to repair bile duct injury.
Sectionectomy
Sectionectomy is an anatomic liver resection that removes one of the liver's four Couinaud sections, each with its own blood supply and bile drainage, preserving maximal functional liver tissue.
Selective internal radiation therapy
Selective internal radiation therapy (SIRT), also called radioembolization, is a liver-directed cancer treatment that injects radioactive microspheres into arteries feeding liver tumors, sparing normal liver.
Simultaneous resection
Simultaneous resection is a surgical strategy in which a primary bowel tumor and its liver metastases, most often colorectal cancer, are removed in a single operation under one general anesthetic rather than in two staged procedures.
Total pancreatectomy
Total pancreatectomy is an operation that removes all pancreatic tissue, performed mainly for pancreatic tumors and high-risk pancreases; first done successfully in 1942, it causes lifelong diabetes requiring insulin and enzyme replacement.
Transarterial chemoembolization
Transarterial chemoembolization (TACE) is an interventional radiology procedure that delivers chemotherapy through tumor-feeding hepatic arteries with embolic agents, the recommended first-line treatment for intermediate-stage hepatocellular carcinoma when surgery is unsuitable.
Transduodenal Sphincterotomy
Transduodenal sphincterotomy (transduodenal sphincteroplasty, TDS) is open surgical incision of the sphincter of Oddi via a duodenotomy, now reserved for failed or impossible endoscopic sphincterotomy, altered anatomy, and pancreas divisum.
Trisectionectomy
Trisectionectomy, also called extended hepatectomy, is a major liver resection removing three of the four Couinaud sections, either right or left, to treat extensive tumors while leaving a functioning remnant.
Venous resection
Venous resection is a surgical technique that removes a segment of the portal or superior mesenteric vein together with a pancreatic tumor, restoring vein continuity afterward.
