Assessment and Plan: Chronic Abdominal Pain with Heavy Intermittent Alcohol Use, Post-prandial Vomiting, and Early Satiety
Assessment
This patient's presentation is most consistent with alcohol-related gastroparesis and/or alcoholic hepatitis, with the critical priority being immediate evaluation for life-threatening complications including mesenteric ischemia, alcoholic hepatitis, and impending alcohol withdrawal.
Primary Diagnostic Considerations
Alcohol-Related Gastroparesis (Most Likely)
- The triad of post-prandial vomiting, early satiety, and chronic abdominal pain strongly suggests gastroparesis 1
- Heavy alcohol consumption (30 beers = approximately 420g alcohol every other day, averaging 210g/day) far exceeds the threshold for alcohol-related organ damage 1
- Gastroparesis symptoms—nausea, vomiting, early satiety, and abdominal pain—match this patient's presentation exactly 1, 2
Alcoholic Hepatitis (Must Rule Out)
- This drinking pattern (>210g/day average for likely >6 months) meets diagnostic criteria for alcoholic hepatitis risk 1
- Critical labs needed immediately: AST, ALT, bilirubin, INR 1
- Look for: jaundice, tender hepatomegaly, ascites, encephalopathy 1
- AST/ALT ratio >1.5 with AST >50 IU/mL and bilirubin >3 mg/dL confirms alcoholic hepatitis 1
- If present, 28-day mortality is 12-15% and 84-day mortality is 14-24% 1
Mesenteric Ischemia (Life-Threatening, Must Exclude)
- Heavy alcohol consumption can cause mesenteric vasoconstriction and bowel ischemia 3
- Chronic abdominal pain with food aversion (early satiety, vomiting) is the classic presentation of chronic mesenteric ischemia 1
- Obtain CT angiography of abdomen immediately to evaluate celiac and mesenteric vessels 1
Impending Alcohol Withdrawal/Delirium Tremens (Highest Mortality Risk)
- Peak risk for delirium tremens is 48-72 hours after last drink, with mortality up to 15% if untreated 4
- If patient presents on a "non-drinking day," they are in the highest-risk window 4
- Initiate prophylactic benzodiazepines within first 6-24 hours to prevent progression to delirium tremens 4
Secondary Considerations
Chronic Pancreatitis
- Alcohol consumption >70g/day for >7 years causes chronic pancreatitis 5
- This patient's intake (210g/day average) far exceeds this threshold 5
- Chronic abdominal pain with early satiety and vomiting can indicate pancreatic exocrine insufficiency 6
Gastric Outlet Obstruction or Stricture
Immediate Workup (Within Hours)
Laboratory Studies
- Complete metabolic panel: AST, ALT, bilirubin, alkaline phosphatase, albumin, glucose 1
- CBC with differential: evaluate for infection, anemia 1
- Coagulation studies: PT/INR (elevated in severe alcoholic hepatitis) 1
- Lipase: evaluate for acute-on-chronic pancreatitis 5
- Blood alcohol level: if >0.08 g/dL, patient is legally intoxicated; if zero, withdrawal risk is highest 4, 7
- Uric acid: if elevated with high-dose pancreatic enzymes planned 8
Imaging
- CT angiography of abdomen with IV contrast:
Alcohol Withdrawal Prophylaxis
- CIWA-Ar protocol with scheduled benzodiazepines (e.g., chlordiazepoxide 50-100mg q6h or lorazepam 2-4mg q6h) 4
- Thiamine 100mg IV/IM daily before any glucose administration 4
- Folate 1mg daily, multivitamin 4
- Monitor vital signs q4h for tachycardia, hypertension, tremor 4
Diagnostic Testing (Within 24-72 Hours)
Gastric Emptying Study
- 4-hour scintigraphic gastric emptying study with standardized low-fat egg-white meal is the gold standard for diagnosing gastroparesis 1
- Must verify proper methodology: 4-hour duration (not 2-hour), standardized meal, proper imaging protocol 1
- Delayed emptying confirms gastroparesis; normal emptying suggests functional dyspepsia 1, 2
Upper Endoscopy (EGD)
- Exclude mechanical obstruction: stricture, malignancy, gastric outlet obstruction 1
- Evaluate for: gastritis, peptic ulcer disease, esophageal varices (if cirrhosis suspected) 1
- Perform when patient is hemodynamically stable and withdrawal risk managed 4
Management Plan
Alcohol Cessation (Highest Priority for Long-Term Outcomes)
Abstinence is the single most important intervention for this patient's morbidity and mortality.
- When patients with alcoholic chronic pancreatitis stop drinking, abdominal pain disappears in the majority, pancreatic function deteriorates more slowly, and death rate diminishes 5
- Alcohol cessation improves gastroparesis symptoms and prevents progression of liver disease 1, 5
- Refer to addiction medicine or psychiatry for medication-assisted treatment (naltrexone, acamprosate, disulfiram) and counseling 5
- Inpatient detoxification is strongly recommended given this level of consumption and withdrawal risk 4
Gastroparesis Management (If Confirmed)
Dietary Modifications
- Small, frequent meals (6 meals/day) with reduced fat and fiber 1, 6
- Liquid or pureed foods if solid food intolerance persists 1, 6
- Avoid carbonated beverages and alcohol 1
Pharmacologic Treatment for Nausea/Vomiting
- Metoclopramide 5-10mg PO/IV 30 minutes before meals and at bedtime (first-line prokinetic) 1
- Maximum 12 weeks due to tardive dyskinesia risk 1
- Ondansetron 4-8mg PO/IV q8h PRN for breakthrough nausea 1
- Prochlorperazine 5-10mg PO/IV q6-8h PRN as alternative antiemetic 1
Neuromodulators for Abdominal Pain
- Tricyclic antidepressants (e.g., nortriptyline 10-25mg qHS, titrate to 50-75mg) are first-line for gastroparesis-associated abdominal pain 1
- NEVER use opioids for gastroparesis pain—they worsen gastric emptying and create dependency 1
Advanced Therapies (If Refractory)
- Gastric electrical stimulation (GES): consider if refractory nausea/vomiting after 3-6 months of medical therapy failure and patient is opioid-free 1
- G-POEM (gastric per-oral endoscopic myotomy): consider only at centers of excellence for severe refractory cases with documented severe gastric emptying delay 1
Chronic Pancreatitis Management (If Present)
Pancreatic Enzyme Replacement
- Pancrelipase (CREON) 25,000-75,000 lipase units with each meal and 10,000-25,000 units with snacks 8
- Starting dose: 500-1,000 lipase units/kg/meal for adults with chronic pancreatitis 8
- Take with meals/snacks, swallow whole with adequate liquid 8
- Do not exceed 2,500 lipase units/kg/meal or 10,000 units/kg/day to avoid fibrosing colonopathy 8
- Monitor for: steatorrhea improvement, weight stabilization, abdominal pain reduction 8, 5
Pain Management
- Abstinence is the most effective pain intervention 5
- Tricyclic antidepressants or SNRIs for neuropathic pain component 1
- Avoid opioids due to addiction risk, worsening gastroparesis, and poor long-term outcomes 1
Nutritional Support
Immediate Nutritional Assessment
- Screen for malnutrition: albumin, prealbumin, weight loss percentage 6
- Calorie count and dietary consultation 6
Nutritional Interventions (Stepwise)
- Oral diet modification: small, frequent, low-fat meals 1, 6
- Oral nutritional supplements: liquid calories if solid food intolerance 6
- Enteral nutrition via nasojejunal or jejunostomy tube: if oral intake inadequate after 2-4 weeks 6
- Parenteral nutrition (TPN): only as last resort for short-term use due to infection and line complication risks 6
Critical Pitfalls to Avoid
Alcohol Withdrawal Management
- Do NOT wait for withdrawal symptoms to start benzodiazepines—prophylaxis must begin within 6-24 hours of last drink 4
- Do NOT discharge patient without addressing withdrawal risk—peak DT risk is days 2-5, not day 1 4
- Always give thiamine BEFORE glucose to prevent Wernicke encephalopathy 4
Gastroparesis Management
- Do NOT use opioids for pain—they worsen gastroparesis and create dependency 1
- Do NOT diagnose gastroparesis without proper 4-hour gastric emptying study—2-hour studies are inadequate 1
- Do NOT crush or chew pancreatic enzyme capsules—this destroys enteric coating and causes oral mucosa irritation 8
Mesenteric Ischemia
- Do NOT delay CT angiography if chronic mesenteric ischemia suspected—mortality is high if bowel infarction occurs 1, 3
- Classic triad: postprandial pain, food aversion/weight loss, cardiovascular disease history 1
Alcoholic Hepatitis
- Do NOT miss alcoholic hepatitis—28-day mortality is 12-15% 1
- AST/ALT ratio <1.5 occurs in <2% of biopsy-proven alcoholic hepatitis—if ratio is <1.5, consider alternative diagnosis 1
Follow-Up and Monitoring
Short-Term (1-2 Weeks)
- Reassess symptoms: nausea, vomiting, abdominal pain, oral intake 1
- Weight and nutritional status 6
- Liver function tests if alcoholic hepatitis suspected 1
- Alcohol abstinence verification: consider PEth testing (>200 ng/mL indicates heavy drinking) 7
Medium-Term (4-12 Weeks)
- Repeat gastric emptying study if symptoms persist despite treatment 1
- Assess for pancreatic exocrine insufficiency response: steatorrhea, weight, abdominal pain 8, 5
- Addiction medicine follow-up: medication-assisted treatment adherence, counseling 5
Long-Term (3-6 Months)
- Pain reassessment: if pain persists despite abstinence and medical therapy, consider surgical evaluation (lateral pancreaticojejunostomy if ductal dilation present) 5
- Consider advanced gastroparesis therapies (GES, G-POEM) only if refractory to medical management after 3-6 months 1
- Ongoing addiction treatment and relapse prevention 5
