Abdominal and GI System Review

Abdominal Regions and Organs

  • Right Hypochondrium: Liver (right lobe), Gallbladder

  • Right Iliac Fossa: Appendix, Cecum

  • Right Flank: Ascending colon, Right kidney

  • Left Hypochondrium: Spleen

  • Left Iliac Fossa

  • Left Flank: Descending colon, Left kidney

  • Epigastric Region, Umbilical Region, Hypogastric Region (suprapubic)

Subjective Data

  • Health History: GI conditions, surgeries, meds

  • Review of Systems

  • Family history

  • Functional assessment: substance use, diet

  • Focused Assessment: OPQRSTU

Bowel Movements (BM)

  • Assessment: frequency, color, consistency

  • Abnormalities:

    • Dyschezia: pain/straining

    • Tenesmus: feeling of fullness after emptying

    • Diarrhea

    • Hematochezia: bloody stool (lower GI bleed)

    • Melena: black, tarry stool (upper GI bleed)

    • Steatorrhea: fat malabsorption

Physical Exam: IAPP (Inspection, Auscultation, Percussion, Palpation)

  • Preparation: lighting, exposure, empty bladder, supine position

Inspection

  • Skin color and condition: Cullen's & Turner's sign (intraabdominal bleeding)

  • Umbilicus: midline and inverted

  • Symmetry: hernias, masses

  • Contour: flat or rounded (normal)

  • Movement: aortic pulsation, peristalsis

Auscultation

  • Bowel Sounds: RLQ and moving clockwise

    • Normoactive: 5-30 times per minute

    • Hypoactive: <5 sounds/min; decreased motility

    • Absent: no sounds after 5 minutes; obstruction

    • Hyperactive: >30 times/minute; increased motility

  • Vascular Sounds: Use bell to listen for bruits over aorta, renal, iliac, and femoral arteries

Percussion

  • Tympany: normally predominates

  • Dullness: liver, fecal matter, ovarian cyst

  • Fist Percussion: CVA tenderness indicates kidney inflammation.

Palpation

  • Light palpation: tenderness, surface characteristics

  • Deep palpation: advanced technique for organs

  • Guarding: voluntary (emotions, pain), involuntary (inflammation, spasm)

Palpating Abdominal Organs

  • Liver: RUQ, smooth, firm, nontender, extend no more than 2cm outside right costal margin

  • Gallbladder: RUQ, normally not palpable

  • Spleen: LUQ, normally not palpable; can rupture easily

Aging Adult Considerations

  • Increased abdominal fat

  • Risk for nutritional deficits

  • Constipation

  • Decreased abdominal musculature

  • Reduced abdominal rigidity with peritonitis

Disorders of the Abdomen & GI System

GERD

  • Stomach contents move into the esophagus.

  • Clinical findings: Regurgitation, heartburn (pyrosis), pain worse when lying down.

Peptic Ulcer Disease

  • Ulcer in lower esophagus, stomach, or duodenum

  • Clinical Findings:

    • Epigastric pain (burning, gnawing)

    • Duodenal: relieved with food

    • Gastric: worse with food

    • Nausea, bloating; melena or hematemesis (bleeding)

Bowel Obstruction

  • Mechanical or paralytic ileus

  • S/S: abdominal pain/distension, N/V, constipation, lack of flatus, visible peristalsis

Ascites

  • Fluid collection in abdominal cavity.

  • S/S: Protuberant contour, jaundice (cirrhosis), dyspnea, diminished bowel sounds, shifting dullness.

Appendicitis

  • Dull abdominal pain to severe RLQ pain

  • McBurney's point tenderness; Rovsing's sign

  • Iliopsoas/Psoas sign, Obturator sign

  • Rebound tenderness; N/V/D, fever

Cholecystitis

  • Bile duct obstruction.

  • S/S: RUQ pain radiating to shoulder, worse after fatty meals

  • Positive Murphy Sign (inspiratory arrest)

  • Fever, steatorrhea, N&V, possible jaundice

Diverticulitis

  • Inflammation of diverticula.

  • S/S: "Crampy" LLQ pain, fever, chills, localized tenderness, blood-streaked stool.

Inflammatory Bowel Disease

  • Ulcerative Colitis (UC): bloody diarrhea with mucus

  • Crohn’s: symptoms depend on location of fissures/fistula/ulcer

  • Both: abdominal pain, weight loss, diarrhea

Peritonitis

  • Bacterial peritoneal inflammation

  • S/S: Fever, tachycardia, bloating, pain, rigidity, rebound tenderness, hypoactive BS

Abdominal Aortic Aneurysm (AAA)

  • Dilation of abdominal aorta

  • Asymptomatic until rupture

  • S/S: Impending doom, bruit, abdominal/lower back pain, palpable pulsation

Diabetes Mellitus

  • Elevated serum glucose levels.

  • S/S: Polyphagia, polydipsia, polyuria, paresthesia, poor wound healing, weight loss.

  • Diabetic ketoacidosis (DKA): Kussmaul respirations, fruity breath
    Hypoglycemia: confusion, diaphoresis, shakiness

Urinary Tract Infection (UTI)

  • Dysuria, frequency, urgency, fever, suprapubic pain, malodorous urine, CVA tenderness. Labs: WBC count, (+) Urine culture. Treatment: Abx, Cystoscopy
