Study Notes
Gastrointestinal (GI) System Overview
- Major Functions: Ingestion, digestion, elimination
- GI Tract Components: Pharynx, esophagus, stomach, small intestine, large intestine
- Accessory Organs: Liver, pancreas, gallbladder, bile ducts, teeth, salivary glands
Abdominal Quadrants and Organ Locations
- RUQ: Ascending colon, duodenum, gallbladder, right kidney, liver, right ureter, head of pancreas, transverse colon
- LUQ: Descending colon, left kidney, body and tail of pancreas, spleen, stomach, transverse colon, left ureter
- RLQ: Appendix, ascending colon, bladder, cecum, rectum, right ureter, small intestine, female reproductive organs (ovaries, uterus, fallopian tubes), male reproductive organs (prostate, spermatic cord)
- LLQ: Bladder, descending colon, small intestine, sigmoid colon, left ureter, female reproductive organs (ovaries, uterus, fallopian tubes), male reproductive organs (prostate, spermatic cord)
Abdominal Muscles
- Protection and Function: Three layers of abdominal wall muscles protect internal organs and facilitate movements like coughing, sneezing, and childbirth.
- Surgical Implications: Abdominal surgery recovery can be prolonged due to pain in these muscles.
Abdominal Obstruction vs. Ileus
- Bowel Obstruction: Blockage preventing food/fluid passage through the intestines (small and large). Symptoms: intermittent crampy abdominal pain, loss of appetite, vomiting, constipation, abdominal swelling.
- Paralytic Ileus: Peristalsis ceases, mimicking obstruction. Symptoms: absent bowel sounds, constipation, bloating, pain, nausea, vomiting (dehydration).
Post-Operative Abdominal Surgery Considerations
- Potential Complications: Bowel/intestinal obstruction, paralytic ileus, incision dehiscence/evisceration.
- Management: NG tube placement, NPO status, IV fluids, monitoring fluids/electrolytes, vital signs.
Liver Anatomy and Function
- Location: Largest solid organ, below diaphragm in RUQ, extending to left midclavicular line.
- Structure: Four lobes
- Palpation: Soft consistency if palpable.
- Key Functions: Digestion, metabolism, regulation (glucose storage, protein and clotting factor formation, cholesterol and bile production, iron and vitamin storage, detoxification).
Liver Disease Assessment
- Palpation: Palpable liver, firm or hard; difficulty palpation due to rib cage; may be palpable on inspiration.
- Significance of Findings: Clues to liver disease and potential complications, such as cancer.
Jaundice (Icterus)
- Clinical Presentation: Yellowing of skin, mucous membranes, and sclera due to elevated bilirubin.
- Urine: Dark (tea-colored) urine.
- Stools: Pale/gray (due to lack of bile).
- Causes: Gallstones, malignant bile duct obstructions, infectious hepatitis, infections, cancer (painful or painless).
- Associated Symptoms: Variable symptoms depending on underlying cause, potential for itchiness.
Kidney Assessment
- CVA Tenderness: Percussion over the costovertebral angle (12th rib and spine) to assess for pain (infection/kidney stones).
Common GI Symptoms
- Pain (acute or chronic): Abdominal, epigastric, radiating.
- Digestive Issues: Nausea, vomiting (blood, hematemesis), loss of appetite, early satiety, dysphagia (difficulty swallowing), odynophagia (painful swallowing).
- Bowel Changes: Diarrhea, constipation, change in bowel habits, last BM.
- Jaundice: Visually assess skin color.
- Urinary Issues: Suprapubic pain, dysuria (painful urination), frequency, urgency, incontinence, hematuria (blood in urine), flank pain, hesitancy (males).
Abdominal Pain Causes
- GERD: Epigastric/chest pain, burning, discomfort.
- PUD: Epigastric, radiating back pain.
- Appendicitis: Periumbilical (migrates to RLQ), McBurney's point tenderness.
- Cholecystitis: RUQ pain, radiating to right shoulder.
- Bowel Obstruction: Variable pain, potentially severe.
- Pancreatitis: Epigastric pain, radiating back.
- Diverticulitis: LLQ pain.
- Associated Symptoms: Nausea, vomiting, anorexia, indigestion.
Abdominal Pain Types
- Visceral Pain: Vague, non-localized, deep, squeezing, aching; organ stretching or distension.
- Parietal Pain: More severe, localized, steady aching; inflamed peritoneum (peritonitis); aggravated by movement and coughing.
Bowel Function Issues
-
Diarrhea: Increased stool water content.
- Classify as acute, persistent, or chronic.
- Constipation: Fewer than three bowel movements per week, hard, lumpy stools.
- Stool Variations: Black/tarry (melena - upper GI bleed), red blood (hematochezia - lower GI bleed), grey/pale.
- Be aware of medications that affect stool appearance (e.g., iron).
Urinary Abnormalities
- Frequency and Nocturia: Decreased bladder capacity, infection, stones, tumors, BPH (benign prostatic hyperplasia).
- Polyuria: Excessive urine production (diabetes insipidus, kidney disease).
- Incontinence (types): Stress, urge, overflow, functional, secondary medications.
Abdominal Assessment
- Inspection: Symmetry, visible pulsations, bulges (hernias, ascites), skin color (jaundice), venous patterns.
- Auscultation: Bowel sounds (5-24/minute, hyperperistalsis, absent sounds). Aorta for bruits (abnormal sounds).
- Percussion: Fluid (ascites), tenderness.
- Palpation: Light (guarding, rigidity, rebound tenderness), deep (liver, masses, tenderness).
- CVA Tenderness: Over costovertebral angle, kidney disease or infection.
- Important Considerations: Pain location, intensity, duration for accurate diagnosis.
