Study Notes

Pancreatic Disorders Overview

MRI and ERCP are utilized for diagnosing tumors and disorders affecting the pancreas, intestine, and bile duct.
Early clinical manifestations of pancreatic tumors may include asymptomatic conditions, notably jaundice and dull epigastric pain.
Poor prognosis associated with pancreatic tumors; most patients have a life expectancy of 5 to 12 months post-diagnosis, with a 5-year survival rate at just 8%.

Biliary System Function

The biliary system comprises the gallbladder and bile ducts, primarily responsible for transporting bile from the liver to the duodenum for fat digestion.
Bile consists of cholesterol, bilirubin, and bile salts, and acts as a critical enzyme in fat breakdown.

Cholecystitis

Inflammation of the gallbladder can occur due to bile flow obstruction, categorized as calculous (with gallstones) or acalculous (without gallstones).
Risk factors for cholecystitis include abdominal surgery, long-term IV nutrition, prolonged fasting, obesity, rapid weight loss, diabetes, and certain medications.
Gallstones (cholelithiasis) are categorized into cholesterol (most common), pigmented (from excess bilirubin), and mixed stones.

Clinical Manifestations of Cholecystitis

Presenting symptoms include right upper quadrant (RUQ) pain, rebound tenderness, fever, and tachycardia, with potential jaundice and dark urine from impaired bile flow.
Positive Murphy's sign may indicate gallbladder inflammation.
Avoiding crash diets is essential to prevent triggering acute episodes.

Chronic Pancreatitis

Characterized by prolonged inflammation and fibrosis of the pancreas; it is an incurable condition.
Diagnosis involves labs (amylase/lipase levels, bilirubin, alkaline phosphatase), imaging, and stool analysis for fat content.
Symptoms include upper abdominal pain, recurrent pain with overeating, diarrhea, steatorrhea, and complications such as diabetes.

Management of Chronic Pancreatitis

Pain management includes medication along with electrolyte and nutritional support.
Surgery may be needed but is risky and not always appropriate, including options like the Peustow procedure for bile flow diversion and laparoscopic drainage for complications.

Pancreatic Cancer

The cause of pancreatic cancer remains unknown; risk factors include smoking, high-fat diets, diabetes, chronic pancreatitis, family history, and increased age (>60).
Treatment options consist of surgery (e.g., Whipple procedure), chemotherapy, and radiation.

Acute Pancreatitis

Symptoms present suddenly, characterized by severe abdominal pain, nausea/vomiting, and signs of potential fluid imbalance such as tachycardia and hypotension.
Diagnostics include elevated amylase and lipase levels, imaging studies like CT scans, and ERCP for assessing bile ducts.

Management of Acute Pancreatitis

Prioritize aggressive hydration, pain relief, reduced pancreatic secretions, and managing electrolyte imbalances.
Avoid triggers, including nicotine and high-fat intake, and consider cholecystectomy if gallstones are implicated.
Early antibiotic initiation is crucial to prevent infections in inflamed pancreatic tissue.

Patient Education

Patients are advised to avoid alcohol, caffeine, and fatty foods due to their stimulation of pancreatic secretions.
Educating about managing diabetes if it develops as a complication of chronic pancreatitis.
