Pancreatic head carcinoma – A malignant tumor that forms in the head of the pancreas, the widest part of the pancreas that sits in the curve of the duodenum. As it grows, it often invades surrounding tissues and may block the bile duct, causing jaundice. The disease typically progresses silently in its early stages, with symptoms such as abdominal pain, weight loss, and digestive problems appearing as the tumor grows. Pancreatic head carcinoma can spread to nearby lymph nodes and other organs over time.
Intraductal papillary mucinous neoplasm (IPMN) – A type of tumor that grows within the pancreatic ducts, characterized by papillary growths that produce mucin, a thick fluid. IPMNs can involve the main pancreatic duct, branch ducts, or both. They range from benign to malignant, with those in the main duct having higher potential for cancer development. Some IPMNs may cause symptoms such as abdominal pain, pancreatitis, or jaundice, while others remain asymptomatic. Over time, these neoplasms can progress and potentially transform into invasive pancreatic cancer.
Postoperative pancreatic fistula (POPF) – A complication where pancreatic fluid leaks from the pancreatic anastomosis after pancreatic surgery. The condition occurs when there is a failure of healing at the site where the pancreas is connected to another organ. POPF is characterized by drainage of amylase-rich fluid from surgical drains or from abnormal collections near the pancreas. It can progress from a biochemical leak (Grade A) to clinically relevant fistulas (Grades B and C) that may require intervention.
Delayed gastric emptying (DGE) – A condition following pancreatic surgery where the stomach takes longer than normal to empty its contents into the small intestine. Patients experience nausea, vomiting, bloating, and inability to tolerate oral intake. DGE can range from mild cases requiring minimal intervention to severe cases necessitating prolonged nasogastric tube drainage. The condition typically resolves over time but can significantly extend hospital stay and delay return to normal nutrition.
Post pancreatectomy hemorrhage (PPH) – Bleeding that occurs after pancreatic surgery, which can be early (within 24 hours) or late (after 24 hours). It may originate from the surgical site or surrounding blood vessels. PPH ranges in severity from mild bleeding to life-threatening hemorrhage requiring urgent intervention. The bleeding can be intraluminal (into the digestive tract) or extraluminal (into the abdominal cavity), with varying clinical presentations depending on the location and extent.
Chyle leakage (CL) – A complication following pancreatic surgery where lymphatic fluid (chyle) leaks into the abdominal cavity. It occurs due to disruption of lymphatic vessels during the operation, particularly when extensive lymph node dissection is performed. Chyle leakage is characterized by milky-appearing fluid in surgical drains, especially after fat-containing meals. The condition can lead to nutritional deficiencies and fluid imbalances if persistent.
Bile leakage (BL) – A complication where bile escapes from the biliary anastomosis or from injured bile ducts following pancreatic surgery. It is characterized by bilious fluid in surgical drains or collections. Bile leakage can range from small, self-limiting leaks to significant drainage requiring intervention. The condition may lead to localized or diffuse peritonitis if bile spreads throughout the abdominal cavity.
Post-pancreatectomy acute pancreatitis (PPAP) – Inflammation of the pancreatic remnant that occurs after partial removal of the pancreas. It is characterized by elevated pancreatic enzymes and typical symptoms of pancreatitis. PPAP results from manipulation of the pancreas during surgery, leading to activation of digestive enzymes within the gland. The condition ranges from mild, self-limiting inflammation to severe pancreatitis with potential complications such as necrosis or fluid collections.
