Pancreatitis and Acupuncture Treatment in Tokyo

What is Pancreatitis?

Pancreatitis is broadly classified into two types:

1. Acute Pancreatitis (AP): This form develops suddenly and is often triggered by gallstones, excessive alcohol consumption, certain medications, or infections. Symptoms include severe upper abdominal pain radiating to the back, nausea, vomiting, and fever. Severe cases can lead to systemic inflammatory response syndrome (SIRS) or multiple organ dysfunction syndrome (MODS), with a mortality rate of around 19% in severe cases, as reported by West China Hospital researchers.
2. Chronic Pancreatitis (CP): This is a progressive condition characterized by ongoing inflammation, leading to permanent pancreatic damage. Common causes include long-term alcohol use, genetic factors, or recurrent acute pancreatitis. Symptoms include chronic abdominal pain, weight loss, and digestive issues due to enzyme deficiencies. Chronic pancreatitis increases the risk of diabetes and pancreatic cancer if untreated.

Causes of Pancreatitis

The causes of pancreatitis vary depending on whether it is acute or chronic:

• Gallstones: These can block the pancreatic duct, causing enzyme buildup and inflammation.
• Alcohol Consumption: Excessive alcohol use is a leading cause of both acute and chronic pancreatitis.
• Medications: Certain drugs, such as corticosteroids or antibiotics, can trigger pancreatitis.
• Infections: Viral or bacterial infections may inflame the pancreas.
• Genetic Factors: Mutations in genes like PRSS1 and SPINK1 are associated with hereditary pancreatitis.
• Trauma or Surgery: Physical injury to the pancreas can lead to inflammation.
• Metabolic Disorders: Conditions like hypertriglyceridemia can contribute to pancreatitis.

Symptoms of Pancreatitis

The symptoms of pancreatitis can range from mild to severe and include:

• Abdominal Pain: Sharp or dull pain in the upper abdomen, often radiating to the back, worsened by eating fatty foods.
• Nausea and Vomiting: Common in acute pancreatitis, contributing to dehydration and discomfort.
• Fever: A sign of inflammation or infection, particularly in severe cases.
• Abdominal Distension: Caused by intestinal paralysis or fluid accumulation.
• Weight Loss: Common in chronic pancreatitis due to malabsorption of nutrients.
• Diarrhea or Fatty Stools: Resulting from impaired fat digestion in chronic cases.

If symptoms like severe abdominal pain or persistent vomiting occur, immediate medical attention is critical, as these may indicate a life-threatening condition.

Complications of Pancreatitis

Untreated or severe pancreatitis can lead to serious complications:

• Systemic Inflammatory Response Syndrome (SIRS): A widespread inflammatory response that can lead to organ failure.
• Multiple Organ Dysfunction Syndrome (MODS): A life-threatening condition affecting multiple organs.
• Pancreatic Necrosis: Death of pancreatic tissue, increasing infection risk.
• Diabetes: Damage to insulin-producing cells can lead to type 2 diabetes.
• Pancreatic Cancer: Chronic inflammation increases the risk of malignancy.

Given the severity of these complications, early intervention and integrative treatment approaches, including acupuncture, are vital for improving outcomes.

Conventional Treatments for Pancreatitis

Conventional treatments for pancreatitis focus on managing symptoms, addressing the underlying cause, and preventing complications. These include:

• Hospitalization: For acute pancreatitis, patients often require fasting, intravenous fluids, and pain management to stabilize their condition.
• Medications: Analgesics like opioids or non-steroidal anti-inflammatory drugs (NSAIDs) are used for pain relief, though their efficacy and safety are limited.
• Surgery: In cases of gallstone-induced pancreatitis or pancreatic necrosis, surgical intervention may be necessary.
• Enzyme Replacement Therapy: For chronic pancreatitis, enzyme supplements aid digestion.
• Lifestyle Changes: Avoiding alcohol, adopting a low-fat diet, and managing metabolic conditions are critical for long-term management.

While these treatments are effective for many, they often come with side effects, such as opioid dependency or surgical risks. This has led to growing interest in complementary therapies like acupuncture, which offers a non-pharmacological approach to symptom relief.

Acupuncture Treatment

Acupuncture is a TOM practice that involves inserting thin needles into specific points on the body, known as acupoints, to restore balance and promote healing. According to TOM, the body’s vital energy flows through meridians, and disruptions in this flow can lead to illness. Acupuncture aims to regulate Energy, improve blood flow, and stimulate the body’s natural healing processes.

In Western medicine, acupuncture is recognized for its ability to modulate pain, reduce inflammation, and regulate the nervous system. It is often used as an adjunct therapy for conditions like chronic pain, nausea, and gastrointestinal disorders. For pancreatitis, acupuncture, particularly electroacupuncture (EA), has shown promise in alleviating abdominal pain, improving gastrointestinal motility, and reducing inflammation.

How Acupuncture Works

Acupuncture’s mechanisms are multifaceted, involving both TOM and modern scientific principles:

• Neuromodulation: Acupuncture stimulates nerve fibers, releasing endorphins and other neurotransmitters that reduce pain perception. For example, stimulating the LI4 acupoint has been shown to release endorphins, natural painkillers.
• Anti-Inflammatory Effects: Acupuncture modulates inflammatory mediators like tumor necrosis factor-alpha (TNF-α), reducing systemic inflammation.
• Gastrointestinal Regulation: By stimulating acupoints like Zusanli (ST36), acupuncture enhances gastrointestinal motility, addressing symptoms like abdominal distension and ileus.
• Autonomic Nervous System Modulation: Electroacupuncture activates the vagus nerve, triggering the cholinergic anti-inflammatory pathway, which reduces inflammation in conditions like acute pancreatitis.

These mechanisms make acupuncture a valuable tool for managing pancreatitis symptoms, particularly when combined with conventional treatments.

Acupuncture for Pancreatitis: Benefits and Evidence

Acupuncture has been studied for its potential to treat both acute and chronic pancreatitis, with a focus on pain relief, inflammation reduction, and gastrointestinal function improvement. Below, we explore the key benefits supported by recent research.

Benefits of Acupuncture for Pancreatitis

1. Pain Relief:
   • Acupuncture, especially electroacupuncture, has been shown to significantly reduce abdominal pain in pancreatitis. A 2017 study published in Pancreas found that acupuncture provided more pain relief (2.0 ± 1.5 on the Visual Analog Scale) compared to sham stimulation (0.7 ± 0.8) in chronic pancreatitis patients.
   • Electroacupuncture at acupoints like Zusanli (ST36) and Zhigou (TE6) has been effective in reducing visceral pain and abdominal distension in severe acute pancreatitis.
2. Reduction of Inflammation:
   • Studies, such as one published in Frontiers in Molecular Biosciences (2021), indicate that electroacupuncture at Zusanli activates the vagus nerve’s anti-inflammatory pathway, reducing inflammatory markers like TNF-α and improving outcomes in acute pancreatitis.
   • Acupuncture combined with routine treatment (RT) has been shown to lower Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) scores, indicating reduced disease severity.
3. Improved Gastrointestinal Function:
   • Gastrointestinal dysfunction, such as intestinal paralysis, is a common complication of acute pancreatitis. Electroacupuncture at ST36 has been shown to restore intestinal motility by increasing the proportion of cholinergic neurons in the myenteric plexus, as demonstrated in a 2022 study in Wiley Online Library.
   • Acupuncture reduces the time to resume normal diet and shortens hospital stays, as reported in a 2019 meta-analysis in Pancreas.
4. Enhanced Prognosis:
   • By addressing pain, inflammation, and gastrointestinal issues, acupuncture improves overall prognosis. A 2019 systematic review in BMJ Open found that acupuncture plus routine treatment improved the total effective rate and reduced hospital stays compared to routine treatment alone.
5. Minimal Side Effects:
   • Unlike opioids or NSAIDs, acupuncture has few side effects, making it a safe adjunct therapy. The National Center for Complementary and Integrative Health notes that complications from acupuncture are rare when performed by licensed practitioners.

Recent Studies on Acupuncture for Pancreatitis

Recent research highlights acupuncture’s efficacy for pancreatitis:

• 2019 Systematic Review and Meta-Analysis (Pancreas): This study analyzed 12 randomized controlled trials (RCTs) and found that acupuncture plus routine treatment significantly improved gastrointestinal function, reduced TNF-α levels, and shortened hospital stays compared to routine treatment alone. However, the authors noted the need for more high-quality RCTs to confirm these findings.
• 2021 Meta-Analysis (Frontiers in Psychiatry): This review of 19 studies (n=1,503) confirmed that acupuncture, including electroacupuncture, significantly reduced abdominal pain and distension in acute pancreatitis, with lower Visual Analog Scale (VAS) scores and faster relief times.
• 2018 RCT Protocol (Trials Journal): A multi-center trial evaluated the pain-relieving effects of electroacupuncture using local (CV12, CV13) and distal (LI4, PC6, SP6, GB39, ST36, ST37) acupoints. Preliminary results suggested improved pain control compared to conventional therapy.
• 2021 Study (Frontiers in Molecular Biosciences): Electroacupuncture at Zusanli (ST36) reduced inflammation in animal models of acute pancreatitis via the vagus nerve-mediated cholinergic anti-inflammatory pathway, suggesting a mechanistic basis for its effects.

While these studies are promising, researchers emphasize the need for more rigorous RCTs to establish acupuncture’s efficacy and optimal protocols for pancreatitis treatment.

Key Acupoints for Pancreatitis Treatment

Acupoints are specific points on the body targeted during acupuncture to achieve therapeutic effects. The selection of acupoints for pancreatitis is based on TOM principles and clinical evidence, focusing on points that regulate gastrointestinal function, reduce pain, and modulate inflammation. Below are the key acupoints commonly used for pancreatitis:

1. Zusanli (ST36):
   • Location: On the lower leg, about four finger-widths below the kneecap, lateral to the shinbone.
   • Function: Known as the “Stomach 36” point, Zusanli is widely used for gastrointestinal disorders. It regulates pancreatic function, reduces abdominal pain, and improves intestinal motility. Studies show that electroacupuncture at ST36 enhances cholinergic neuron activity, alleviating intestinal paralysis in severe acute pancreatitis.
   • Evidence: A 2022 study in Wiley Online Library found that EA at ST36 improved intestinal propulsion rates in a rat model of severe acute pancreatitis.
2. Zhongwan (CV12):
   • Location: On the midline of the abdomen, halfway between the navel and the base of the sternum.
   • Function: This point harmonizes the stomach and spleen, relieving abdominal pain and distension. It is often used in local electroacupuncture protocols for pancreatitis.
   • Evidence: A 2018 RCT protocol in Trials Journal included CV12 in local EA treatments, showing reduced pain severity in acute pancreatitis patients.
3. Shangwan (CV13):
   • Location: On the midline of the abdomen, two finger-widths above CV12.
   • Function: Supports digestion and alleviates nausea and vomiting, common symptoms of pancreatitis.
   • Evidence: Used alongside CV12 in clinical trials, CV13 contributes to gastrointestinal symptom relief.
4. Zhigou (TE6):
   • Location: On the forearm, three finger-widths above the wrist crease, between the radius and ulna.
   • Function: Regulates Energy flow and alleviates abdominal distension and pain, particularly in severe acute pancreatitis with paralytic ileus.
   • Evidence: A 2016 study in Zhongguo Zhen Jiu found that EA at TE6 reduced abdominal pain and distension in severe acute pancreatitis.
5. Hegu (LI4):
   • Location: On the hand, in the webbing between the thumb and index finger.
   • Function: Known for its analgesic effects, LI4 stimulates endorphin release, reducing visceral pain. It also supports gastrointestinal motility.
   • Evidence: MRI studies have shown that stimulating LI4 releases endorphins, contributing to pain relief in pancreatitis.
6. Neiguan (PC6):
   • Location: On the inner forearm, two finger-widths above the wrist crease.

    • Function: Specifically targets pancreatic function, reducing pain and inflammation.
    • Evidence: Used in combination with other acupoints in clinical studies, Yishu enhances treatment efficacy for pancreatitis.

Electroacupuncture vs. Traditional Acupuncture

Electroacupuncture (EA) involves applying a mild electric current to acupuncture needles to enhance stimulation. For pancreatitis, EA is particularly effective due to its ability to modulate the vagus nerve and reduce inflammation more effectively than traditional acupuncture. Studies, such as those in Frontiers in Molecular Biosciences (2021), have shown that EA at ST36 significantly reduces inflammatory markers and improves survival rates in animal models of acute pancreatitis.

Traditional acupuncture, using manual needle insertion, is also effective but may have a milder effect on severe cases. Both methods are safe when performed by licensed practitioners, with EA often preferred for acute pancreatitis due to its stronger anti-inflammatory and analgesic effects.

Integrating Acupuncture with Conventional Treatment

Acupuncture is most effective when used as an adjunct to conventional treatments. For acute pancreatitis, patients typically receive standard-of-care therapies like fasting, IV fluids, and pain management, while acupuncture targets pain and gastrointestinal symptoms. For chronic pancreatitis, acupuncture can reduce reliance on analgesics and improve quality of life.

A 2015 study in Experimental and Therapeutic Medicine found that integrated traditional Oriental medicine (ITOM), including acupuncture, improved outcomes in acute pancreatitis by downregulating PRSS1 and SPINK1 expression, reducing inflammation, and improving pancreatic function. Combining acupuncture with Western medicine offers a holistic approach, addressing both symptoms and underlying causes.

Safety and Considerations

Acupuncture is generally safe, with minimal side effects when performed by a licensed practitioner. The National Center for Complementary and Integrative Health reports that complications, such as bruising or mild soreness, are rare and resolve quickly. However, patients with pancreatitis should:

• Consult their healthcare provider before starting acupuncture, especially if they have severe acute pancreatitis or are hospitalized.
• Ensure the acupuncturist is licensed and experienced in treating gastrointestinal conditions.
• Avoid acupuncture if they have bleeding disorders or are on blood thinners, as this may increase the risk of bruising.

Patients with suspected pancreatitis should seek immediate medical attention and not rely solely on acupuncture for treatment, especially in acute cases requiring emergency care.

How to Get Started with Acupuncture for Pancreatitis

Finding a Qualified Acupuncturist

To ensure safe and effective treatment, choose an acupuncturist with:

• Licensure: Most states require acupuncturists to be licensed. Verify credentials through state licensing boards or organizations like the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM).
• Experience: Look for practitioners with experience in treating pancreatitis or gastrointestinal disorders.
• Integration with Medical Care: Choose an acupuncturist who collaborates with your healthcare team for a coordinated approach.

What to Expect During an Acupuncture Session

• Initial Consultation: The acupuncturist will assess your medical history, symptoms, and TOM diagnostics (e.g., pulse and tongue examination).
• Treatment Plan: Sessions typically last 30–60 minutes, with needles inserted at specific acupoints. Electroacupuncture may be used for enhanced effects.
• Frequency: For acute pancreatitis, daily sessions for 4–7 days may be recommended, while chronic pancreatitis may require weekly sessions for several weeks.
• Sensations: You may feel a mild tingling or warmth at the needle sites, but discomfort is minimal.

Future Directions and Research Needs

While acupuncture shows promise for pancreatitis, more research is needed to:

• Conduct high-quality, large-scale RCTs to confirm efficacy and safety.
• Standardize acupoint selection and treatment protocols for consistency.
• Explore long-term effects of acupuncture on chronic pancreatitis outcomes.
• Investigate the molecular mechanisms, such as vagus nerve modulation, to better understand acupuncture’s effects.

Researchers at West China Hospital are leading efforts to generate high-quality evidence for TOM, including acupuncture, through trials like the 2020 study on Chaienergyn chengenergy decoction, which may inform future integrative approaches.
