Celiac Plexus Neuralgia
Videos
Overview
Celiac plexus neuralgia is chronic abdominal pain caused by irritation, inflammation, or compression of the celiac nerve plexus—a major nerve bundle supplying the stomach, liver, pancreas, and upper abdominal organs. It may occur as a primary nerve disorder or as a secondary effect of conditions such as MALS, celiac artery compression, pancreatitis, or chronic inflammation. Patients often experience burning, deep, or radiating pain that worsens after eating or with stress.
Causes
Causes include nerve irritation from vascular compression (MALS/celiac artery compression), chronic inflammation, pancreatitis, abdominal surgery, trauma, or idiopathic nerve dysfunction. In many patients, neuralgia persists even after the original trigger resolves.
Risk Factors
Risk factors include MALS, celiac artery compression, pancreatitis, chronic abdominal inflammation, prior abdominal surgery, and conditions affecting the autonomic nervous system.
How Celiac Plexus Neuralgia Affects the Body
Irritation of the celiac plexus disrupts normal nerve signaling to the upper abdominal organs, causing chronic pain, nausea, early satiety, and digestive dysfunction. Pain may radiate to the back or worsen after meals.
Complications
Complications include chronic pain, weight loss, anxiety around eating, reduced quality of life, and in severe cases, malnutrition.
Symptoms & Signs
Symptoms include burning or deep upper abdominal pain, pain radiating to the back, nausea, early satiety, bloating, and worsening pain after meals or stress. Some patients experience relief when leaning forward.
Diagnosis
Diagnosis includes clinical evaluation, CT or MRI to rule out structural causes, Doppler or CTA if vascular compression is suspected, and diagnostic celiac plexus block to confirm nerve‑mediated pain.
Differential Diagnosis
Includes MALS, celiac artery compression, pancreatitis, peptic ulcer disease, gallbladder disease, gastroparesis, and functional abdominal pain.
Lifestyle Modifications
Patients may benefit from stress reduction, small frequent meals, hydration, and avoiding triggers such as large meals or intense exercise. These measures help symptoms but do not treat the underlying nerve dysfunction.
Treatment Options
Treatment includes medications (neuromodulators), nerve blocks, celiac plexus neurolysis, and surgical decompression if vascular compression is present. Patients with MALS or celiac artery compression often improve after ligament release and nerve decompression.
When to See a Doctor
Seek evaluation if you experience persistent upper abdominal pain, especially if imaging is normal or symptoms worsen after meals.
When to Seek Treatment
Treatment is recommended when pain interferes with eating, daily activities, or weight maintenance, or when nerve‑mediated pain is confirmed.
Long-Term Outlook
Long‑term outcomes are excellent when the underlying cause is treated. Patients with persistent neuralgia may benefit from ongoing nerve‑based therapies.
Prognosis
Many patients improve with nerve‑directed therapy or decompression surgery when vascular compression is present. Chronic cases may require long‑term pain management.
