Study Notes
General Pathology: Approach to Gastrointestinal Disease
- Gastrointestinal disease approach involves functional anatomy and physiology, digestive disease history, and exploration, as well as investigations and abdominal pain.
- Common symptoms include pain, which can be physiological or unspecific.
- Acute pain may be caused by conditions like appendicitis.
- Referred pain can radiate to other areas.
Intended Learning Objectives
- Introduce clinical presentation of gastrointestinal diseases, specifically abdominal pain.
- Introduce investigations in gastrointestinal disease, including imaging, endoscopy, laboratory tests, and functional tests.
Functional Anatomy & Physiology
- Digestive tube components include mouth, pharynx, esophagus, stomach, duodenum, ileum, jejunum, colon, rectum, and anus.
- Secretions related to digestion include salivary glands, gastric secretions, bile, pancreatic juice, and bowel secretions, along with hormones.
GI Symptomatology
-
Abdominal Pain:
- Visceral pain results from organ distension, inflammation, or obstruction, often diffuse and periumbilical.
- Parietal pain originates from parietal peritoneum, localized precisely.
- Non-digestive pain can be from other systems (urinary, gynecological, muscular).
- Common causes include functional ailments, inflammatory bowel syndrome, and functional dyspepsia; heartburn is a common symptom.
-
Nausea and Vomiting:
- Can be from digestive or non-digestive causes.
- Potential causes include bowel obstruction, gastroparesis, intestinal pseudo-obstruction, medications, endocrine disorders, and neurological issues.
- Possible causes include functional and pathological conditions like inflammatory bowel syndrome, functional dyspepsia, infections or organ disturbances.
-
Consequences:
- Hydration imbalances, peptic esophagitis, intra-abdominal pressure increases, and airway aspiration of vomitus are possible.
GI Symptomatology (continued)
- Jaundice: Yellowing of skin and eyes due to elevated bilirubin levels. Potential causes are liver and biliary tree diseases.
- Altered bowel habits: Changes in frequency, consistency, or form of bowel movements. Factors include dietary habits, medications, endocrine disorders, or tumors/inflammoations.
- Altered bacterial composition: A significant change in the types or numbers of bacteria within the digestive system.
Evaluation of the Patient with GI Disease
- History: Includes personal/family history, medications/eating habits, symptoms' timing and pattern, and relation to other factors (Rome criteria and Bristol stool chart).
- Physical Exam: Includes general inspection, abdomen inspection/palpation/percussion, hernia/mass search, and rectal/vaginal examination.
- Laboratory tests: Include blood cell counts, biochemistry (liver & pancreas enzymes), acid-base status, serology (viral studies), tumor markers, stool analysis for parasites/calprotectin.
- Radiology (Plain X-ray): Useful for identifying air, calcification, and bone issues (perforation, obstruction).
- Contrast Radiology: Using barium or non-ionic contrast agents to help visualize digestive structures and identify issues like fistulas, motor syndromes, and obstructions.
- Ultrasonography: Useful for imaging solid organs, fluids, and bowel walls, can be used interventionally. Some drawbacks include the subjective nature and potential interference by air.
- CT Scanning: Provides good image definition for detecting gas, fluid, and bone; it offers whole-body studies and 3D reconstruction. Drawbacks include drawbacks like radiation exposure and the potential issues assessing the pelvis.
- MR Imaging: Excellent soft tissue imaging with contrast, but drawbacks include cost and time constraints, as well as potential interference from metal implants.
- Endoscopy: Allows for visualization of the mucosal lining, biopsies, and therapeutic procedures. Drawbacks include the invasive nature and need for preparations/sedation.
- Colonoscopy: Visualizes the colon, helpful for biopsies, diagnostic purposes, and therapeutic intervention.
- Endoscopic Retrograde Cholangiopancreatography (ERCP): A procedure using a specialised endoscope to visualize the bile and pancreatic ducts.
-
Functional Studies:
- pH monitoring for esophageal pH measurement.
- Manometry (esophageal & rectal) to evaluate motility and function of the esophagus or rectum related to potential conditions like GERD or issues with bowel movement.
- Breath test to monitor lactose or carbohydrate metabolism, as well as other aspects of gastrointestinal and nutritional processes.
- Absorption and digestion studies to explore digestive capabilities and processes, nutritional absorption and related disorders.
Abdominal Pain
-
Types:
- Nociceptive (somatic, visceral)
- Neuropathic
- Referred
- Psychogenic
-
Classification of acute abdominal pain:
- Inflammatory
- Perforative
- Hemorrhagic
- Obstructive intestinal
- Obstructive enterovascular
- Mixed
- Common causes: Mild conditions like gastroenteritis, dyspepsia, dysmenorrhea, and non-specific abdominal problems account for most cases (90%). Acute cases frequently include unspecific abdominal pain (34%), appendicitis (28%), and cholecystitis (10%).
