Gastroparesis

Gastroparesis is a chronic, debilitating neuromuscular disorder characterized by delayed gastric emptying of solid food in the absence of mechanical gastric outlet obstruction. It is characterized by symptoms such as postprandial fullness, early satiety, nausea, vomiting, and bloating.

• Idiopathic (36%): Most common form, often following a viral prodrome (post-viral gastroparesis).
• Diabetic (29%): Secondary to long-standing type 1 or type 2 diabetes mellitus.
• Postsurgical (13%): Damage to the vagus nerve during fundoplication, bariatric surgery, or esophagectomy.
• Other Causes: Neurological disorders (Parkinson's, multiple sclerosis), autoimmune diseases (scleroderma), medications (GLP-1 receptor agonists, opioids), and hypothyroidism.

The primary mechanism involves neuromuscular dysfunction of the stomach, including:

1. Loss of Interstitial Cells of Cajal (ICC): Depletion of these gastric pacemaker cells impairs coordinated antral contractions.


2. Autonomic Neuropathy: Vagal nerve damage impairs antral-pyloric coordination.


3. Loss of Nitric Oxide Synthase (NOS): Impairs pyloric relaxation, leading to pylorospasm and delayed emptying.

• Prevalence: Estimated at 13.8 per 100,000 men and 37.8 per 100,000 women.
• Demographics: Highly female predominant (4:1 female-to-male ratio).
• Age of Onset: Typically presents in young to middle-aged adults (ages 30–50).

• Long-standing, poorly controlled diabetes mellitus
• Prior upper abdominal or thoracic surgeries
• Autoimmune connective tissue disorders (scleroderma)
• Chronic use of opioids or GLP-1 receptor agonists
• Parkinson's disease

• Vital Signs: Orthostatic hypotension and tachycardia if dehydrated.
• Inspection: Abdominal distension; temporal and supraclavicular muscle wasting in advanced malnutrition.
• Palpation: Mild epigastric tenderness; no guarding or rigidity.
• Auscultation: Succussion splash heard over the epigastrium 1 hour or more after a meal when rocking the patient's torso, indicating retained fluid and gas in the stomach.

• A. Clinical Assessment: Validated symptom scoring via the Gastroparesis Cardinal Symptom Index (GCSI).
• B. Laboratory Testing: Assessment of electrolytes, glycated hemoglobin (HbA1c), and nutritional markers.
• C. Imaging Studies: Esophagogastroduodenoscopy (EGD) to rule out mechanical obstruction.
• D. Functional Tests: Gastric Emptying Scintigraphy (GES) of solid foods over 4 hours (Diagnostic standard).
• E. Biopsy Findings: Done during endoscopy to exclude eosinophilic gastroenteritis or malignancy; gastric biopsy (rarely done) shows ICC depletion.
• F. Genetic Testing: Not indicated for routine clinical evaluation.
• G. Differential Diagnosis: Functional dyspepsia, mechanical obstruction, cyclic vomiting syndrome.

Glycated Hemoglobin (HbA1c)

• Type: Blood Test


• Purpose: Identify or evaluate glycemic control in suspected diabetic gastroparesis


• Expected Findings: Elevated (>6.5%) in poorly controlled diabetes


• Interpretation: Identifies underlying poorly controlled diabetes as the probable etiology Serum Electrolytes


• Type: Blood Test


• Purpose: Evaluate secondary complications of recurrent vomiting


• Expected Findings: Hypokalemia, hypochloremia, and metabolic alkalosis


• Interpretation: Indicates severe dehydration and loss of gastric acid requiring IV fluid rehydration

• Gastric Emptying Scintigraphy (GES): Gold standard. Measures retention of a radiolabeled solid meal (typically a Tc-99m labeled egg-white meal) at 1, 2, and 4 hours. Retention of >10% of the meal at 4 hours is diagnostic of gastroparesis.
• Esophagogastroduodenoscopy (EGD): Evaluates for physical blockages or gastric outlet obstruction. Typical findings include retained food in the stomach despite an overnight fast (>8 hours) without mechanical blockages.

• Gastric Outlet Obstruction (GOO): Distinguished from gastroparesis by mechanical stenosis or mass visible on EGD or barium swallow.
• Functional Dyspepsia: Has overlapping symptoms, but solid gastric emptying scintigraphy is normal.
• Cyclic Vomiting Syndrome: Characterized by acute, episodic, stereotypical vomiting bouts with completely asymptomatic intervals.

• Malnutrition and severe weight loss
• Electrolyte imbalances and acute kidney injury from dehydration
• Gastric Bezoars: Solid masses of undigested material blocking the pylorus
• Mallory-Weiss mucosal tears from chronic retching

• Idiopathic: Up to 40% of post-viral cases improve spontaneously over several years.
• Diabetic: Chronic and progressive, requiring long-term multidisciplinary management.
• Quality of Life: Markedly reduced in patients with severe, treatment-refractory symptoms.

• Maintaining tight glycemic control in patients with diabetes.
• Avoiding high-risk surgical procedures that compromise vagal nerve integrity.
