    Study Notes

    Abdominal Examination

    • Palpation is essential in assessing the severity and location of abdominal pain.
    • Avoid starting palpation at the point of maximal pain, as this can induce voluntary guarding.
    • Distinguish voluntary guarding from involuntary guarding (a sign of peritonitis) by observing if the muscles relax during inspiration.
    • Common causes of abdominal pain include inflammation, infection, perforation, obstruction, infarction, strangulation, hemorrhage, injury, and medical conditions.

    Upper Abdominal Pain

    • Upper abdominal pain can be caused by various conditions including gastritis, peptic ulcer disease, gallstones, pancreatitis, GERD, esophagitis, hepatitis, aortic dissection, Boerhaave’s syndrome, and acute cholecystitis.

    Oesophagus

    • The oesophagus is an 8-inch tube lined with stratified squamous epithelium, transporting food through peristalsis.
    • It comprises three layers: mucosa, submucosa, and muscularis externa.
    • The lower oesophageal sphincter prevents stomach acid reflux.
    • The oesophagus begins at the level of C6 and terminates at T11.
    • There are upper and lower oesophageal sphincters regulating air intake and gastric reflux.

    Oesophageal Vasculature

    • The thoracic part of the oesophagus receives blood supply from the thoracic aorta, the inferior thyroid artery.
    • The abdominal portion is supplied by the left gastric artery and the left inferior phrenic artery.
    • Venous drainage from the oesophagus follows two routes: portal circulation via the left gastric vein and systemic circulation via the azygos vein.

    Oesophagus Physiology

    • The oesophagus exhibits a virtual lumen that expands during swallowing.
    • The sphincters remain contracted at rest, preventing air aspiration and reflux.
    • Swallowing is divided into voluntary (chewing, bolus formation) and involuntary phases (initiating the swallowing reflex).
    • The pharyngeal phase involves closure of passages, relaxation of the UES, and temporary respiration suppression.

    Oesophageal Damage

    • Gastric contents contain harmful components like HCl, pepsin, and trypsin, which can damage the oesophagus.
    • The oesophageal epithelium's resistance involves pre-epithelial (mucus, bicarbonate), epithelial (phospholipid layer), and post-epithelial factors (bloodflow).
    • Bloodflow is crucial for nutrient supply, removal of noxious agents, and acid-base equilibrium.

    Gastroesophageal Reflux Disease (GERD)

    • GERD can be classified into three phenotypes: non-erosive reflux disease, erosive esophagitis, and Barrett's oesophagus.
    • Non-erosive reflux disease presents with symptoms but lacks mucosal damage.
    • Erosive esophagitis involves visible erosions or mucosal damage.
    • Barrett's oesophagus is a precancerous condition where the squamous epithelium is replaced by intestinal-like epithelium.

    Pancreatic Anatomy and Vasculature

    • The pancreas is a gland responsible for producing digestive enzymes and hormones like insulin.
    • It is supplied by branches of the splenic, gastroduodenal, and superior mesenteric arteries.
    • Venous drainage from the pancreas occurs through the splenic and superior mesenteric veins.

    Acute Pancreatitis

    • Acute pancreatitis is characterized by reversible pancreatic parenchymal injury with inflammation.
    • It is divided into two types: interstitial oedematous pancreatitis and necrotising pancreatitis.

    Pancreas Protections and Pathophysiology

    • The pancreas is normally protected from self-digestion by producing inactive proenzymes (zymogens), activating trypsin only in the small intestine, and secreting trypsin inhibitors.
    • The inappropriate activation of pancreatic enzymes, particularly trypsinogen, within the pancreas, triggers acute pancreatitis.

    Acute Pancreatitis Causes

    • Alcohol consumption and biliary tract disease are the most common causes of acute pancreatitis, accounting for about 80% of cases.
    • Other triggers include metabolic disorders, hypercalcemia, medications, injury, ischemia, infections, and hereditary conditions.

    Acute Pancreatitis Complications

    • Persistent pain and elevated amylase levels may indicate the presence of pseudocysts.
    • Complications of pseudocysts include infection, rupture, hemorrhage, or obstruction.
    • Symptomatic pseudocysts may require decompression.

    Alcohol-Induced Acute Pancreatitis

    • Alcohol transiently increases contraction of the sphincter of Oddi and leads to protein-rich pancreatic fluid secretion causing duct obstruction.
    • Alcohol directly damages acinar cells through oxidative stress, promoting free radical production, and activating pro-inflammatory transcription factors.

    Post-CABG Pancreatitis

    • Elevated amylase levels can occur after CABG surgery due to pancreatic manipulation.
    • Necrotizing pancreatitis after CABG is a rare complication, typically identified by CT scan.
