Comprehensive Overview of Gastrointestinal Conditions

1. PEPTIC ULCER DISEASE (PUD)

Peptic ulcer disease affects 1% of the US population with a lifetime prevalence of 5-10%, and complications occur in 10-20% of patients, with hemorrhage being the most common complication (73% of cases) and perforation the most lethal (23.5% 30-day mortality). 1, 2

Definition

Peptic ulceration results from acid-peptic damage to the gastroduodenal mucosa, causing mucosal erosion that exposes underlying tissues to digestive secretions 1.

Causes and Risk Factors

  • Primary causes:

    • Helicobacter pylori infection (42% of cases) 2
    • NSAID/aspirin use (36% of cases) 2
    • Smoking and alcohol abuse 1
  • High-risk factors for complications:

    • Prior peptic ulcer disease or complication (2-4 fold increased risk) 3
    • Advanced age (4% increased risk per year) 3
    • Concurrent corticosteroid or anticoagulant use 3
    • High-dose or multiple NSAIDs 3
    • Low-dose aspirin combined with NSAIDs (>10-fold increased risk) 3

Pathophysiology

The disease develops when aggressive factors (acid, pepsin, H. pylori, NSAIDs) overwhelm protective mechanisms (mucus, bicarbonate, prostaglandins, blood flow). H. pylori causes chronic inflammation and disrupts mucosal defense, while NSAIDs inhibit cyclooxygenase enzymes, reducing protective prostaglandin synthesis 1, 4.

Clinical Manifestations

  • Epigastric pain (often relieved by food in duodenal ulcers, worsened by food in gastric ulcers)
  • Nausea and vomiting
  • Complicated presentations:
    • Hematemesis (vomiting fresh blood) or coffee-ground vomiting 5
    • Melena (black tarry stools) 5
    • Acute abdominal pain with peritoneal signs (perforation)
    • Early satiety and vomiting (obstruction)

Complications

  • Hemorrhage (73%): Annual incidence 0.02-0.06%, 8.6% 30-day mortality 1
  • Perforation (9%): Annual incidence 0.004-0.014%, 23.5% 30-day mortality, causes 40% of ulcer-related deaths 1
  • Pyloric obstruction (3%) 2

Management by Nursing Care Plan

Assessment Phase

  • Immediate evaluation parameters:

    • Vital signs: pulse >100 bpm, systolic BP <100 mmHg indicate shock 5
    • Hemoglobin level and serial monitoring (>20 g/L drop in 24 hours indicates rebleeding) 5
    • Lactate levels for tissue perfusion 1
    • Signs of peritonitis: rigid abdomen, rebound tenderness, absent bowel sounds
  • Risk stratification:

    • Document Boey Score or PULP score for perforated ulcers 1
    • Assess for high-risk features: age >60, comorbidities, anticoagulation

Nursing Diagnosis

  • Acute pain related to mucosal erosion
  • Risk for deficient fluid volume related to hemorrhage
  • Risk for infection related to perforation
  • Deficient knowledge regarding disease management

Planning and Implementation

For Bleeding Ulcers:

  • Resuscitation targets:

    • Maintain systolic BP >100 mmHg 1
    • Hemoglobin >70 g/L (restrictive transfusion strategy unless active cardiac disease) 1
    • Normalize lactate levels 1
  • Pharmacological management:

    • High-dose PPI: omeprazole 80 mg IV bolus, then 8 mg/hour infusion for 72 hours post-endoscopy 5
    • Erythromycin 250 mg IV 30-60 minutes pre-endoscopy to clear stomach 1
  • Monitoring:

    • Continuous vital signs in high-dependency unit 5
    • Serial hemoglobin every 4-6 hours initially
    • Monitor for rebleeding: fresh hematemesis, melena with hemodynamic instability 5

For Perforated Ulcers:

  • NPO status immediately
  • Nasogastric tube insertion for decompression
  • Broad-spectrum antibiotics within 1 hour 1
  • Fluid resuscitation with crystalloids
  • Prepare for emergency surgery or non-operative management based on clinical stability 1

For Uncomplicated Ulcers:

  • Acid suppression:

    • First-line: Vonoprazan (P-CAB) for rapid, potent acid suppression 6
    • Alternative: PPI (omeprazole 20-40 mg daily or lansoprazole 30 mg daily) for 4-8 weeks 2
    • Gastric ulcers >2 cm require 8 weeks treatment 2
  • H. pylori eradication (if positive testing):

    • Standard triple therapy (if low clarithromycin resistance): PPI + amoxicillin 1000 mg + clarithromycin 500 mg, all twice daily for 14 days 1
    • Sequential therapy (if high clarithromycin resistance): PPI + amoxicillin for 5 days, then PPI + clarithromycin + metronidazole for 5 days 1
    • Second-line: Levofloxacin 500 mg + amoxicillin 1000 mg + PPI for 10 days 1
    • Eradication reduces recurrence from 50-60% to 0-2% 2
  • NSAID-related ulcers:

    • Discontinue NSAID (heals 95% of ulcers, reduces recurrence from 40% to 9%) 2
    • If NSAID continuation necessary: switch to lower-risk NSAID + PPI + eradicate H. pylori 2
    • For aspirin users: continue aspirin with PPI therapy 3

Patient Education

  • Medication adherence:

    • Complete full course of H. pylori eradication therapy
    • Take PPIs 30 minutes before breakfast for optimal effect
    • Avoid NSAIDs; use acetaminophen for pain instead
  • Lifestyle modifications:

    • Smoking cessation (mandatory counseling and referral to cessation services)
    • Limit alcohol consumption
    • Avoid foods that trigger symptoms
    • Stress management techniques
  • Warning signs requiring immediate medical attention:

    • Vomiting blood or coffee-ground material
    • Black, tarry stools
    • Severe, sudden abdominal pain
    • Dizziness or fainting

Evaluation

  • Symptom resolution within 2-4 weeks
  • Endoscopic healing confirmation at 4-8 weeks for gastric ulcers
  • H. pylori eradication confirmation with urea breath test or stool antigen 4 weeks post-treatment 4
  • No recurrence at 6-12 month follow-up
  • Patient demonstrates understanding of prevention strategies

2. GASTROESOPHAGEAL REFLUX DISEASE (GERD)

GERD symptoms occur monthly in almost 50% of US adults and weekly in 20%, with strong evidence linking chronic GERD to esophageal adenocarcinoma, though the absolute cancer risk in any individual remains low. 7

Definition

GERD occurs when gastric contents reflux into the esophagus, causing troublesome symptoms (heartburn, regurgitation) and/or complications (esophagitis, strictures, Barrett esophagus) 7.

Causes and Risk Factors

  • Lower esophageal sphincter dysfunction
  • Hiatal hernia (associated with more severe GERD degrees C and D) 8
  • Obesity and increased intra-abdominal pressure
  • Dietary factors: fatty foods, chocolate, caffeine, alcohol
  • Medications: calcium channel blockers, nitrates, anticholinergics
  • Smoking
  • Pregnancy

Pathophysiology

Transient lower esophageal sphincter relaxations allow gastric acid and pepsin to contact esophageal mucosa. The esophageal epithelium lacks protective mechanisms present in the stomach, leading to inflammation. Chronic exposure can cause metaplastic changes (Barrett esophagus) with malignant potential 7.

Clinical Manifestations

  • Typical symptoms:

    • Heartburn (retrosternal burning)
    • Regurgitation of acidic contents
    • Dysphagia (suggests stricture or severe esophagitis)
  • Atypical symptoms:

    • Chronic cough
    • Laryngitis and hoarseness
    • Asthma exacerbations
    • Chest pain (non-cardiac)
    • Dental erosions
  • Presentation variations by condition:

    • With peptic ulcer: heartburn predominates 8
    • Post-gastric resection: bitter taste in mouth 8
    • With hiatal hernia: retrosternal pain 8

Complications

  • Erosive esophagitis (grades A-D)
  • Esophageal stricture causing dysphagia
  • Barrett esophagus (intestinal metaplasia with 0.5% annual cancer risk) 7
  • Esophageal adenocarcinoma (rare but increasing incidence)
  • Aspiration pneumonia
  • Chronic laryngitis

    • Regular exercise program
  • Behavioral modifications:

    • Smoking cessation (mandatory)
    • Avoid tight-fitting clothing around abdomen
    • Stress reduction techniques

Monitoring:

  • No progression to complications

3. GASTRITIS

Gastritis represents inflammation of the gastric mucosa, most commonly caused by H. pylori infection, with atrophic gastritis and intestinal metaplasia significantly increasing gastric cancer risk. 4, 10

Definition

Gastritis is inflammation of the gastric mucosa, classified as acute or chronic, erosive or non-erosive, based on endoscopic and histological findings 10.

Causes and Risk Factors

  • H. pylori infection (most common cause worldwide) 4, 10
  • NSAIDs and aspirin (dose-dependent risk) 10
  • Alcohol abuse (acute erosive gastritis)
  • Stress (critically ill patients, burns, trauma) 10
  • Autoimmune gastritis (pernicious anemia)
  • Bile reflux (post-gastric surgery) 8
  • Infections: CMV, HSV (immunocompromised patients)
  • Chemical injury: corrosives, radiation

Pathophysiology

H. pylori colonizes gastric mucosa, triggering inflammatory cascade with neutrophil and lymphocyte infiltration. Virulent CagA-positive strains cause more severe injury 10. NSAIDs inhibit COX-1, reducing protective prostaglandins and mucus production. Chronic inflammation progresses through stages: superficial gastritis → atrophic gastritis → intestinal metaplasia → dysplasia → adenocarcinoma 4, 10.

Clinical Manifestations

  • Acute gastritis:

    • Epigastric pain or discomfort
    • Nausea and vomiting
    • Loss of appetite

    • Iron deficiency anemia
    • Weight loss

Complications

  • Peptic ulcer disease 10
  • Gastric bleeding (erosive gastritis)
  • Gastric cancer (significantly higher risk with atrophic gastritis and intestinal metaplasia) 10

4. LIVER CIRRHOSIS

Liver cirrhosis represents end-stage chronic liver disease with extensive fibrosis and nodular regeneration, requiring comprehensive management to prevent life-threatening complications including variceal hemorrhage, hepatic encephalopathy, and hepatorenal syndrome.

Definition

Cirrhosis is the irreversible end-stage of chronic liver disease characterized by diffuse hepatic fibrosis, nodular regeneration, and distortion of hepatic architecture, leading to portal hypertension and hepatocellular dysfunction.

Causes and Risk Factors

  • Chronic viral hepatitis: Hepatitis B and C
  • Alcohol abuse (most common in Western countries)
  • Non-alcoholic steatohepatitis (NASH) (increasing prevalence with obesity epidemic)
  • Autoimmune hepatitis
  • Primary biliary cholangitis
  • Primary sclerosing cholangitis
  • Hemochromatosis (iron overload)
  • Wilson disease (copper accumulation)
  • Alpha-1 antitrypsin deficiency
  • Chronic biliary obstruction
  • Cardiac cirrhosis (chronic right heart failure)
  • Medications and toxins

Pathophysiology

Chronic liver injury triggers inflammatory response and stellate cell activation, producing excessive collagen and extracellular matrix. Progressive fibrosis distorts hepatic architecture, creating regenerative nodules surrounded by fibrous bands. This disrupts normal blood flow, causing portal hypertension. Portosystemic shunting and decreased hepatic synthesis lead to complications: varices, ascites, encephalopathy, coagulopathy, and hepatorenal syndrome.

Clinical Manifestations

Compensated Cirrhosis (Often Asymptomatic):

  • Fatigue and weakness
  • Anorexia and weight loss

  • Ascites and spontaneous bacterial peritonitis
  • Hepatic encephalopathy
  • Hepatorenal syndrome (functional renal failure)
  • Hepatopulmonary syndrome
  • Hepatocellular carcinoma (annual incidence 1-6%)

    • Ammonia level (if encephalopathy suspected)
  • Complication screening:

    • Upper endoscopy for variceal screening
    • Abdominal ultrasound with Doppler (portal vein patency, hepatocellular carcinoma)
    • Alpha-fetoprotein every 6 months (hepatocellular carcinoma surveillance)

Nursing Diagnosis

  • Risk for bleeding related to coagulopathy and varices
  • Excess fluid volume related to portal hypertension and hypoalbuminemia
  • Acute confusion related to hepatic encephalopathy
  • Imbalanced nutrition: less than body requirements related to anorexia and malabsorption
  • Risk for infection related to immunocompromise
  • Impaired skin integrity related to edema and pruritus
  • Ineffective breathing pattern related to ascites
  • Deficient knowledge regarding disease management and complications

Planning and Implementation

5. INTESTINAL OBSTRUCTION

Intestinal obstruction is a surgical emergency requiring prompt recognition and intervention, with mortality ranging from 2% for simple obstruction to 25% for strangulated obstruction.

Definition

Intestinal obstruction is mechanical or functional blockage of the intestinal lumen preventing normal passage of intestinal contents, classified as small bowel obstruction (SBO) or large bowel obstruction (LBO), and as partial or complete, simple or strangulated.

Causes and Risk Factors

Small Bowel Obstruction:

  • Adhesions (60-75% of cases, most common after abdominal surgery)
  • Hernias (15-20%): inguinal, femoral, umbilical, incisional
  • Malignancy (10-15%): primary or metastatic
  • Crohn's disease (strictures) 11
  • Intussusception
  • Volvulus
  • Foreign bodies or bezoars
  • Gallstone ileus

Large Bowel Obstruction:

  • Colorectal cancer (60% of cases)
  • Diverticular disease (strictures)
  • Volvulus (sigmoid or cecal)
  • Fecal impaction
  • Inflammatory bowel disease (strictures)
  • Hernias

Risk Factors:

  • Prior abdominal surgery (adhesions)
  • History of hernias
  • Inflammatory bowel disease
  • Malignancy
  • Advanced age
  • Chronic constipation

Pathophysiology

Mechanical obstruction causes proximal bowel distension with gas and fluid accumulation. Increased intraluminal pressure impairs venous return, causing bowel wall edema and further distension. Bacterial overgrowth occurs. If arterial blood flow becomes compromised (strangulation), ischemia develops, progressing to necrosis and perforation. Fluid sequestration in bowel lumen and third-spacing cause dehydration and electrolyte imbalances. Bacterial translocation and perforation lead to peritonitis and sepsis.

Clinical Manifestations

Classic Tetrad:

  • Abdominal pain: Colicky, cramping (small bowel) or constant (strangulation)
  • Vomiting: Early and bilious (proximal SBO) or feculent (distal SBO/LBO)
  • Abdominal distension: More prominent in LBO
  • Obstipation: Inability to pass gas or stool (complete obstruction)

Physical Examination:

  • Inspection: Distension, visible peristalsis, surgical scars, hernias
  • Auscultation: High-pitched, tinkling bowel sounds (early) or absent (late/strangulation)
  • Percussion: Tympany
  • Palpation:
    • Diffuse tenderness
    • Peritoneal signs (rebound, guarding, rigidity) suggest strangulation or perforation
    • Palpable mass (tumor, hernia)
    • Rectal examination: empty rectum, occult blood

Signs of Strangulation (Surgical Emergency):

  • Severe, constant pain
  • Fever and tachycardia
  • Peritoneal signs
  • Leukocytosis with left shift
  • Metabolic acidosis
  • Bloody stools

Complications

  • Strangulation (10-15% of SBO): Bowel ischemia and necrosis
  • Perforation: Peritonitis, sepsis, death
  • Aspiration pneumonia (from vomiting)
  • Dehydration and electrolyte imbalances: Hypokalemia, hypochloremia, metabolic alkalosis
  • Acute kidney injury (prerenal from dehydration)
  • Sepsis and multiorgan failure
  • Short bowel syndrome (if extensive resection required)
  • Recurrent obstruction (adhesions)

Management by Nursing Care Plan

Assessment Phase

  • Immediate evaluation:

    • Vital signs: tachycardia, hypotension (dehydration/sepsis), fever (strangulation)
    • Pain assessment: severity, character, location
    • Abdominal examination (as above)
    • Hydration status: skin turgor, mucous membranes, urine output
  • Diagnostic workup:

    • Laboratory:

      • Complete blood count (leukocytosis suggests strangulation)
      • Comprehensive metabolic panel (electrolytes, renal function)
      • Lactate (elevated in ischemia)
      • Arterial blood gas (metabolic acidosis)
    • Imaging:

      • Abdominal X-ray (supine and upright): Dilated bowel loops, air-fluid levels, absence of colonic gas
      • CT abdomen/pelvis with IV contrast (gold standard): Identifies level, cause, and complications (strangulation, perforation)
      • Transition point, bowel wall thickening, pneumatosis, portal venous gas

Nursing Diagnosis

  • Acute pain related to bowel distension and ischemia
  • Deficient fluid volume related to vomiting and third-spacing
  • Risk for aspiration related to vomiting

6. HEMORRHOIDS

Hemorrhoids are extremely common, affecting up to 50% of adults by age 50, and are managed conservatively in most cases, with surgical intervention reserved for severe or refractory disease.

Definition

Hemorrhoids are vascular cushions in the anal canal that become pathologically enlarged, causing symptoms. Classified as internal (above dentate line, covered by mucosa) or external (below dentate line, covered by anoderm), and graded I-IV based on prolapse severity.

Causes and Risk Factors

  • Chronic constipation and straining (most common)
  • Prolonged sitting (especially on toilet)
  • Pregnancy and childbirth (increased intra-abdominal pressure)
  • Obesity
  • Low-fiber diet
  • Chronic diarrhea
  • Heavy lifting
  • Portal hypertension (cirrhosis)
  • Aging (weakening of supporting tissues)
  • Genetic predisposition

Pathophysiology

Hemorrhoidal cushions are normal vascular structures providing continence. Pathological hemorrhoids develop when supporting connective tissue deteriorates, allowing cushions to engorge and prolapse. Increased intra-abdominal pressure (straining, pregnancy) and venous congestion contribute. Thrombosis can occur in external hemorrhoids. Chronic bleeding leads to iron deficiency anemia.

Clinical Manifestations

Internal Hemorrhoids:

  • Painless bright red rectal bleeding (most common symptom)
    • Blood on toilet paper or coating stool
    • Dripping into toilet bowl
  • Prolapse (grades II-IV)
  • Mucus discharge
  • Pruritus ani (itching)
  • Sensation of incomplete evacuation
  • Pain only if thrombosed or strangulated

External Hemorrhoids:

  • Perianal swelling or lump
  • Pain (especially if thrombosed)
  • Pruritus
  • Bleeding (if ulcerated)

Grading (Internal Hemorrhoids):

  • Grade I: Bulge into canal, no prolapse
  • Grade II: Prolapse with straining, spontaneous reduction
  • Grade III: Prolapse with straining, require manual reduction
  • Grade IV: Permanently prolapsed, cannot be reduced

Thrombosed External Hemorrhoid:

  • Sudden onset severe perianal pain
  • Tender, tense, bluish perianal lump
  • Most painful in first 48-72 hours

Complications

  • Chronic bleeding: Iron deficiency anemia
  • Thrombosis: Severe pain
  • Strangulation: Prolapsed hemorrhoid with compromised blood supply (severe pain, necrosis)
  • Infection: Perianal abscess (rare)
  • Fecal incontinence: After aggressive surgical treatment

Management by Nursing Care Plan

Assessment Phase

  • History:

    • Bleeding: amount, frequency, color, relationship to bowel movements
    • Pain: severity, timing, character
    • Prolapse: frequency, reducibility

7. ACUTE PANCREATITIS

Acute pancreatitis is a potentially life-threatening inflammatory condition with mortality ranging from 1-2% in mild disease to 20-30% in severe necrotizing pancreatitis, requiring aggressive early resuscitation and supportive care.

Definition

Acute pancreatitis is acute inflammation of the pancreas characterized by abdominal pain and elevated pancreatic enzymes (lipase or amylase >3 times upper limit of normal), with or without organ dysfunction and local or systemic complications.

Causes and Risk Factors

  • Gallstones (40-50% of cases, most common)
  • Alcohol (30-35%, second most common)
  • Hypertriglyceridemia (triglycerides >1000 mg/dL)
  • Post-ERCP (endoscopic retrograde cholangiopancreatography)
  • Medications: Azathioprine, 6-mercaptopurine, valproic acid, thiazides, furosemide, sulfonamides, tetracyclines
  • Hypercalcemia (hyperparathyroidism)
  • Trauma (blunt abdominal trauma, post-surgical)
  • Infections: Mumps, coxsackievirus, CMV, HIV
  • Autoimmune pancreatitis
  • Pancreatic divisum (congenital anomaly)
  • Pancreatic or ampullary tumors
  • Scorpion sting (rare, geographic-specific)
  • Idiopathic (10-20%)

Pathophysiology

Premature activation of pancreatic enzymes (trypsinogen to trypsin) within pancreatic acinar cells causes autodigestion. This triggers inflammatory cascade with cytokine release (TNF-α, IL-1, IL-6), leading to local inflammation and potential systemic inflammatory response syndrome (SIRS). Severe cases develop pancreatic necrosis, fluid collections, and multiorgan dysfunction. Third-spacing of fluids causes hypovolemia. Peripancreatic fat necrosis releases free fatty acids, binding calcium (hypocalcemia). Systemic complications include acute respiratory distress syndrome (ARDS), acute kidney injury, and cardiovascular collapse.

Clinical Manifestations

  • Abdominal pain (hallmark symptom):

    • Epigastric, severe, constant
    • Radiates to back (50%)
    • Worse when supine, improved sitting forward
    • Sudden onset
  • Nausea and vomiting (70-90%)

  • Fever (mild in uncomplicated, high in infected necrosis)

  • Tachycardia

  • Abdominal distension

  • Decreased or absent bowel sounds (ileus)

  • Jaundice (if biliary obstruction)

Physical Examination:

  • Epigastric tenderness
  • Abdominal guarding (may be mild initially)
  • Cullen sign: Periumbilical ecchymosis (hemorrhagic pancreatitis, rare)
  • Grey Turner sign: Flank ecchymosis (hemorrhagic pancreatitis, rare)
  • Decreased breath sounds (pleural effusions)

Severity Classification:

  • Mild (80%): No organ failure, no local/systemic complications
  • Moderately severe (10%): Transient organ failure (<48 hours) or local/systemic complications
  • Severe (10%): Persistent organ failure (>48 hours), high mortality

Complications

Local:

  • Acute peripancreatic fluid collections (first 4 weeks)
  • Pancreatic pseudocyst (>4 weeks, encapsulated)
  • Acute necrotic collection (necrosis + fluid, first 4 weeks)
  • Walled-off necrosis (>4 weeks, encapsulated necrosis)
  • Infected necrosis (high mortality, requires intervention)
  • Pancreatic abscess
  • Splenic/portal vein thrombosis
  • Gastrointestinal bleeding (erosion into vessels)

Systemic:

  • Organ failure:
    • Respiratory: ARDS, pleural effusions
    • Renal: Acute kidney injury
    • Cardiovascular: Shock, myocardial depression
  • Metabolic: Hypocalcemia, hyperglycemia, hypertriglyceridemia

    • Pain assessment: severity (often 8-10/10), location, radiation
    • Hydration status: skin turgor, mucous membranes, urine output
    • Respiratory status: oxygen saturation, breath sounds
    • Abdominal examination: tenderness, distension, bowel sounds
  • Diagnostic criteria (require 2 of 3):

    • Characteristic abdominal pain
    • Serum lipase or amylase >3 times upper limit of normal
    • Characteristic imaging findings (CT, MRI, ultrasound)
  • Laboratory evaluation:

    • Pancreatic enzymes: Lipase (more specific than amylase)
    • Complete blood count: Leukocytosis, hemoconcentration (hematocrit >44% predicts severe disease)
    • Comprehensive metabolic panel: BUN, creatinine, glucose, calcium, liver function tests
    • Arterial blood gas: Hypoxemia, metabolic acidosis
    • Triglycerides: If >1000 mg/dL, likely causative
    • Lactate dehydrogenase, C-reactive protein: Prognostic markers
  • Imaging:

    • Abdominal ultrasound: Identify gallstones (perform within 24 hours)
    • Contrast-enhanced CT: Not routine initially; perform if diagnosis uncertain, no improvement after 48-72 hours, or clinical deterioration
      • Identifies necrosis, fluid collections, complications
      • Delay until after adequate resuscitation (contrast nephropathy risk)
  • Severity assessment:

    • SIRS criteria (≥2 indicates severe):
      • Temperature >38°C or <36°C
      • Heart rate >90 bpm
      • Respiratory rate >20 or PaCO2 <32 mmHg
      • WBC >12,000 or <4,000 or >10% bands

    • Initial: 15-20 mL/kg bolus, then 3 mL/kg/hour for 24-48 hours
    • Targets:
      • Urine output >0.5 mL/kg/hour
      • Heart rate <120 bpm
      • Mean arterial pressure 65-85 mmHg
      • Hematocrit 35-44%

    • Enteral superior to parenteral: Reduces infection, organ failure, mortality
    • Start with low-fat, low-residue formula
    • Advance as tolerated
  • Parenteral nutrition: Only if enteral not tolerated after 5-7 days
  • Avoid prolonged fasting (increases infection risk, delays recovery)

Respiratory Support:

8. OESOPHAGITIS

Oesophagitis is inflammation of the esophageal mucosa, most commonly caused by gastroesophageal reflux (erosive esophagitis), with severity grading guiding treatment intensity and duration. 5

Definition

Oesophagitis is inflammation of the esophageal mucosa from various causes, classified by etiology (reflux, infectious, eosinophilic, medication-induced, radiation) and severity (Los Angeles classification grades A-D for reflux esophagitis).

Causes and Risk Factors

  • Gastroesophageal reflux disease (GERD) (most common, 5-15% of UGIB) 5

  • Infections:

    • Candida (immunocompromised, diabetes, antibiotics, inhaled corticosteroids)
    • Herpes simplex virus (immunocompromised)
    • Cytomegalovirus (severe immunosuppression)
  • Eosinophilic esophagitis:

    • Allergic/immune-mediated
    • Associated with food allergies, atopy
  • Medication-induced:

    • Bisphosphonates (alendronate)
    • NSAIDs
    • Potassium chloride
    • Tetracyclines, doxycycline
    • Iron supplements
    • Quinidine
  • Radiation esophagitis (thoracic radiation therapy)

  • Caustic ingestion (acids, alkalis)

  • Crohn's disease (rare)

Pathophysiology

Reflux esophagitis: Repeated acid and pepsin exposure overwhelms esophageal defenses (saliva, mucus, bicarbonate, epithelial barrier, blood flow), causing mucosal injury, inflammation, erosions, and ulcerations. Chronic inflammation can lead to Barrett esophagus (metaplasia) 7, 8.

Infectious esophagitis: Impaired immunity allows opportunistic organisms to invade esophageal mucosa, causing ulceration and inflammation.

Eosinophilic esophagitis: Food or environmental allergens trigger eosinophil-mediated inflammation, causing mucosal edema, fibrosis, and strictures.

Medication-induced: Direct mucosal contact injury from pills lodging in esophagus, especially at anatomic narrowings (aortic arch, left atrium, lower esophageal sphincter).

Clinical Manifestations

  • Dysphagia (difficulty swallowing):

    • Solids (stricture, eosinophilic esophagitis)
    • Liquids and solids (severe inflammation, motility disorder)
  • Odynophagia (painful swallowing):

    • Severe in infectious and medication-induced esophagitis
    • Suggests ulceration
  • Heartburn and regurgitation (reflux esophagitis)

  • Chest pain (retrosternal, may mimic cardiac pain)

  • Food impaction (eosinophilic esophagitis)

  • Nausea and vomiting

  • Hematemesis or melena (severe erosive esophagitis)

  • Weight loss (chronic, severe cases)

  • Oral thrush (suggests candida esophagitis)

Complications

  • Esophageal stricture (dysphagia, food impaction)
  • Barrett esophagus (intestinal metaplasia, cancer risk) 7, 8
  • Esophageal ulceration and bleeding
  • Perforation (rare, caustic injury, severe infection)
  • Aspiration pneumonia
  • Malnutrition and weight loss
  • Esophageal adenocarcinoma (Barrett progression)

Management by Nursing Care Plan

Assessment Phase

  • Symptom characterization:

    • Dysphagia: onset, progression, solids vs. liquids
    • Odynophagia: severity, timing
    • Heartburn: frequency, severity, triggers
    • Associated symptoms: weight loss, bleeding
  • Risk factor identification:

    • GERD symptoms
    • Immunosuppression (HIV, transplant, chemotherapy, corticosteroids)
    • Medication review (bisphosphonates, NSAIDs)
    • Radiation therapy history
    • Allergies and atopic conditions
  • Physical examination:

    • Oral cavity: thrush (candida)
    • Oropharyngeal lesions (HSV)
    • Weight and nutritional status
    • Abdominal examination
  • Diagnostic evaluation:

    • Upper endoscopy (EGD): Gold standard

      • Visualize mucosa: erythema, erosions, ulcers, strictures, white plaques (candida)
      • Biopsy: histology, culture (infectious), eosinophil count
      • Los Angeles classification (reflux esophagitis):
        • Grade A: ≤5 mm mucosal breaks
        • Grade B: >5 mm breaks, not continuous between mucosal folds
        • Grade C: Continuous breaks between ≥2 mucosal folds, <75% circumference
        • Grade D: Breaks involve ≥75% circumference
    • Barium esophagram: If endoscopy contraindicated or to assess stricture

    • pH monitoring: If reflux suspected but endoscopy normal

    • Esophageal manometry: If motility disorder suspected

Nursing Diagnosis

  • Impaired swallowing related to inflammation or stricture
  • Acute pain related to mucosal ulceration
  • Imbalanced nutrition: less than body requirements related to dysphagia
  • Risk for aspiration related to dysphagia
  • Deficient knowledge regarding disease management

Planning and Implementation

Reflux Esophagitis Management:

  • Pharmacological therapy:

    • PPI: Omeprazole 20-40 mg or esomeprazole 40 mg once daily before breakfast
      • Grade A-B: 4-8 weeks
      • Grade C-D: 8 weeks, then maintenance therapy
    • Healing rates: 80-100% at 4-8 weeks
    • Maintenance therapy: Lowest effective PPI dose (on-demand or daily)
  • Lifestyle modifications:

    • Elevate head of bed 6-8 inches
    • Avoid eating 3 hours before bedtime
    • Weight loss if overweight
    • Avoid trigger foods: fatty foods, chocolate, caffeine, alcohol, citrus, tomatoes
    • Smoking cessation
    • Small, frequent meals
  • Endoscopic therapy:

    • Dilation for strictures
    • Radiofrequency ablation for Barrett esophagus with dysplasia
  • Surgical therapy:

    • Fundoplication for refractory symptoms or patient preference

Infectious Esophagitis Management:

  • Candida esophagitis:

    • Fluconazole 200-400 mg daily for 14-21 days (first-line)
    • Alternatives: Itraconazole solution, voriconazole, echinocandins (refractory cases)
    • Treat underlying immunosuppression if possible
  • HSV esophagitis:

    • Acyclovir 400 mg five times daily or 5 mg/kg IV every 8 hours for 14-21 days
    • Alternatives: Valacyclovir, famciclovir
  • CMV esophagitis:

    • Ganciclovir 5 mg/kg IV every 12 hours for 21-42 days
    • Alternative: Foscarnet (if ganciclovir-resistant)
    • Maintenance therapy if severe immunosuppression

Eosinophilic Esophagitis Management:

  • Dietary therapy:

    • Elimination diet (remove common allergens: milk, eggs, wheat, soy, nuts, seafood)
    • Elemental diet (amino acid-based formula) for severe cases
  • Pharmacological therapy:

    • Topical corticosteroids:
      • Fluticasone 880-1760 mcg twice daily (swallowed, not inhaled)
      • Budesonide oral viscous suspension 1-2 mg twice daily
      • Duration: 8 weeks, then taper
    • PPI: High-dose (may have anti-inflammatory effect independent of acid suppression)
  • Endoscopic dilation: For strictures (higher perforation risk than reflux strictures)

Medication-Induced Esophagitis Management:

  • Discontinue offending medication if possible
  • PPI therapy: Omeprazole 20-40 mg daily for 4-8 weeks
  • Sucralfate suspension: 1 g four times daily (coats and protects mucosa)
  • Prevention:
    • Take pills with full glass of water (8 oz)
    • Remain upright 30 minutes after taking
    • Avoid bedtime dosing
    • Consider liquid formulations if available

Nutritional Support:

  • Dietary modifications:

    • Soft, bland diet if severe odynophagia
    • Small, frequent meals
    • Avoid irritants: spicy, acidic, very hot or cold foods
    • Adequate protein and calories
  • Enteral nutrition:

    • Nasogastric or nasojejunal tube if severe dysphagia
    • Percutaneous endoscopic gastrostomy (PEG) if prolonged (>4 weeks)
  • Parenteral nutrition: If enteral not tolerated

Pain Management:

  • Viscous lidocaine: 15 mL swish and swallow before meals (caution: aspiration risk)
  • "Magic mouthwash": Lidocaine + antacid + diphenhydramine
  • Systemic analgesics: Acetaminophen, opioids if severe (avoid NSAIDs)

Monitoring:

  • Symptom improvement tracking
  • Weight monitoring
  • Nutritional status assessment
  • Medication adherence and side effects
  • Follow-up endoscopy:
    • Reflux esophagitis: If symptoms persist or alarm features
    • Infectious esophagitis: If no improvement after 7-10 days
    • Eosinophilic esophagitis: 8-12 weeks to assess response
    • Barrett esophagus: Surveillance per guidelines (every 3-5 years)

Patient Education

  • Medication adherence:

    • Take PPIs 30-60 minutes before breakfast
    • Complete full course of antifungal/antiviral therapy
    • Proper administration of topical corticosteroids (swallow, do not inhale)
    • Pill-taking technique (water, upright position)
  • Dietary modifications:

    • Identify and avoid trigger foods (reflux)
    • Elimination diet adherence (eosinophilic)
    • Soft diet during acute phase
    • Adequate hydration
  • Lifestyle modifications:

    • Bed elevation technique

    • Persistent vomiting
  • Long-term management:

    • Barrett esophagus requires surveillance
    • Eosinophilic esophagitis is chronic, requires ongoing management
    • Reflux esophagitis often requires maintenance therapy

Evaluation

  • Symptom resolution (dysphagia, odynophagia, heartburn)
  • Endoscopic healing (if repeat endoscopy performed)
  • Adequate nutritional intake and stable weight
  • No complications (stricture, bleeding, perforation)
  • Infection eradicated (if infectious cause)
  • Patient demonstrates understanding of management and prevention
  • Improved quality of life

Common Pitfalls and Caveats Across All Conditions

Diagnostic Pitfalls:

  • Do not assume all epigastric pain is benign; consider cardiac causes, especially in elderly or those with risk factors
  • Do not rely solely on enzyme levels for pancreatitis severity; clinical assessment and imaging are critical
  • Do not delay endoscopy in upper GI bleeding with hemodynamic instability
  • Do not miss alarm features requiring urgent evaluation: weight loss, dysphagia, anemia, age >50 with new symptoms

Treatment Pitfalls:

  • Do not withhold opioids for pain in pancreatitis or bowel obstruction due to outdated concerns
  • Do not use prophylactic antibiotics in acute pancreatitis (increases resistance without benefit)
  • Do not delay H. pylori eradication confirmation (treatment failure common)
  • Do not abruptly stop PPIs in patients on long-term therapy (rebound acid hypersecretion)
  • Do not restrict protein in cirrhosis or hepatic encephalopathy (worsens malnutrition)

Monitoring Pitfalls:

  • Do not rely on single laboratory values; trend over time is more informative
  • Do not miss early signs of decompensation in cirrhosis (subtle mental status changes, increasing ascites)
  • Do not ignore persistent symptoms despite treatment (consider alternative diagnosis or complications)

Patient Education Pitfalls:

  • Do not assume patients understand medical terminology; use plain language
  • Do not provide verbal instructions only; written materials improve adherence
  • Do not neglect to assess health literacy and cultural factors affecting care
