Surgery - Chronic Pancreatitis
Introduction
irreversible parenchymal shrinkage and fibrosis, which results in compromised endocrine and exocrine function and recurring stomach pain, are the hallmarks of this pancreatic chronic inflammatory illness.
Etiology
70% alcohol. 20% are idiopathic.
Rare: Hyperparathyroidism, hypertriglyceridemia, ductal blockage, pancreatic divisum, hereditary pancreatitis, tropical pancreatitis, autoimmune pancreatitis, and recurrent acute pancreatitis.
Epidemiology
UK incidence is 1/100,000 annually, while prevalence is 3/100,000. Age range for alcohol-related diseases: 40–50 years on average.
History
Eating or drinking alcohol can make recurrent, severe epigastric pain worse. This discomfort radiates to the back and is eased by sitting forward. Weight loss, bloating, and pale, unpleasant feces for a long period of time (steatorrhoea).
Examination
Examining the tenderness in the epigastrum. indicators of difficulties, including as malnourishment or weight loss.
Pathogenesis
disruption of the typical ductal dilatation, parenchymal atrophy, calcification, chronic inflammation and fibrosis, cyst and stone development, and pancreatic glandular architecture.
It is believed that pancreatic stellate cells play a part in the formation of extracellular matrix, cytokines, and growth factors in response to damage. These cells change from quiescent fat-storing cells to myofibroblast-like cells. Inflammation and elevated intraductal pressures are linked to pain.
Investigational studies
Blood: glucose tolerance test, glucose ("may indicate endocrine dysfunction"). Lipase and amylase (often normal), immunoglobulins, particularly IgG4 in cases of autoimmune pancreatitis.
USS: Percutaneous or endoscopic: may exhibit post-acoustic shadowing and hyperechoic foci.
MRCP or ERCP: Initially, there are alterations such as branch stumping and dilated main duct. Late signs resemble duct strictures with intermittent dilatation, like a "chain of lakes."
AXR: There could be obvious pancreatic calcification.
CT scan: calcification and pancreatic cysts.
Examinations of the pancreatic exocrine system: Elastase found in feces.
Management
General: The primary forms of treatment are supportive and symptomatic, such as food counseling, quitting smoking and alcohol, managing diabetes, taking oral pancreatic enzyme replacements like Creon, and providing analgesia for severe pain episodes. Managing chronic pain can require expert advice. The celiac ganglia and planchnic nerves are crossed by the sensory nerves that supply the pancreas; different levels of pain alleviation can be obtained with coeliac plexus block (CT or EUS-guided neurolysis) and transthoracic splanchnicectomy.
Sphincterotomy, stone extraction, stricture dilatation, or stenting are examples of endoscopic therapy.
Larger pancreatic stones may occasionally be fragmented by extracorporeal shock-wave lithotripsy before being removed endoscopically.
Surgical: If medical care is ineffective, it can be necessary. The modified Puestow treatment offers lateral pancreaticojejunal drainage; resection (pancreaticoduodenectomy or Whipple's); restricted resection of the pancreatic head (Beger procedure); or a combination of pancreatic duct opening and pancreatic head excavation (Frey procedure).
Complications
Local: pancreatic cancer, duodenal blockage, biliary duct stricture, pseudocysts, and pancreatic ascites.
Systemic conditions include dependency on potent analgesics, diabetes, steatorrhea, low quality of life, and chronic pain syndromes.
Prognosis
unpredictable since pain can get better, stay the same, or get worse. In 60–70% of cases, surgery relieves symptoms, but the effects are frequently short-lived. There is a 10–20 year reduction in life expectancy.
