While cholangitis, and cholecystitis are both conditions affecting the biliary system, they involve different structures:

What are the symptoms of Cholangitis?

Cholangitis can present as either an acute or chronic condition. The symptoms differ depending on the severity, and duration of the disease as below.

Acute Cholangitis Symptoms

The hallmark symptoms of acute cholangitis are collectively known as Charcot’s Triad:

• Fever – often accompanied by chills, fever reflects the body’s immune response to inflammation or infection.
• Jaundice – a yellowing of the skin, and eyes caused by bile leaking into the bloodstream, indicating bile duct obstruction.
• Upper right abdominal pain – this is the area where your biliary system (bile ducts, gallbladder, and liver) is located.

If the condition progresses, additional symptoms may develop due to bile accumulation, and systemic infection, such as:

• Pruritus (itchy skin) – caused by bile acids circulating in the bloodstream.
• Signs of sepsis or shock – these occur when the infection spreads into the bloodstream, and may include:
  • Rapid heart rate (tachycardia)
  • Low blood pressure (hypotension)

When Charcot’s Triad is accompanied by mental confusion, and signs of shock, this is referred to as Reynolds’ Pentad, which is a medical emergency that indicates a severe, life-threatening infection.

Who is at risk of developing Cholangitis?

Cholangitis can affect anyone, but certain individuals are more likely to develop it due to underlying health conditions or structural issues affecting the bile ducts. Some of the risk factors include:

• Age — the likelihood of cholangitis increases with age, particularly in individuals over 60 years old. Ageing is associated with a higher risk of gallstones, reduced bile flow, and a weaker immune response.
• Gender — women may have a slightly higher risk due to their greater tendency to develop gallstones, which are a common cause of cholangitis.
• Gallstones — gallstones that migrate into the bile ducts (choledocholithiasis) can cause blockages, allowing bacteria to accumulate, and trigger infection.
• Bile duct strictures or prior biliary surgery — narrowing of the bile ducts, whether due to inflammation, scarring or past procedures like ERCP or gallbladder removal, can obstruct bile flow, and promote infection.
• Primary sclerosing cholangitis (PSC) — this chronic condition causes inflammation, and scarring of the bile ducts, increasing the risk of recurrent or chronic cholangitis.
• Indwelling stents or drains in the bile duct system — medical devices placed in the biliary tract for a prolonged period, such as stents or drainage tubes, can serve as entry points for bacteria, and increase the risk of infection.
• Pancreatic or bile duct cancer — these malignancies can block the bile ducts, leading to bile stasis, and a heightened risk of cholangitis.
• Congenital or anatomical abnormalities — conditions like choledochal cysts or abnormal bile duct formation can disrupt normal bile flow, and make infections more likely.
• Weakened immune system — individuals with compromised immunity, such as those with diabetes, cancer, HIV or those on immunosuppressive medications, are more vulnerable to severe infections, including cholangitis.

How is Cholangitis diagnosed in Singapore?

Cholangitis is a potentially serious condition that typically presents symptoms such as fever, jaundice, and upper abdominal pain. As such, early diagnosis is critical to prevent complications like sepsis or liver damage. At Dr Lee Chin Li, diagnosis is made through a combination of clinical evaluation, laboratory tests, and imaging studies to confirm infection, and identify any underlying obstruction in the biliary system.

Clinical Evaluation

Your diagnostic journey begins with a thorough consultation. During your visit, our doctor will:

• Take a detailed medical history, focusing on previous history of gallstones, biliary surgery or liver disease.
• Enquire about symptoms such as fever, chills, yellowing of the skin or eyes, nausea, and right upper abdominal pain.
• Perform a physical examination to check for abdominal tenderness, signs of jaundice or other indicators of systemic infection.

Laboratory and Diagnostic Tests

To confirm the diagnosis, and assess the severity of cholangitis, a number of tests may be recommended:

• Blood Tests
  • Blood Cultures – essential in detecting bacteria in the bloodstream, especially in suspected cases of sepsis.
  • Liver Function Tests – elevated liver enzymes, and bilirubin levels can indicate bile duct obstruction or liver inflammation.
  • White Blood Cell Count and CRP – these help determine the presence, and extent of infection or inflammation.

• Imaging Studies
  • Abdominal Ultrasound – often the first-line imaging to detect bile duct dilation, gallstones or other blockages.
  • Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) scan – provides a more detailed view of the biliary tree, and surrounding organs, useful in complex or unclear cases.
• ERCP – both a diagnostic, and therapeutic procedure, ERCP allows direct visualisation of the bile ducts, and can be used to remove stones or place stents.

How is Cholangitis treated in Singapore?

The management of cholangitis depends on the severity of infection, and the underlying cause. Generally, treatment is initiated promptly to stabilise the patient, relieve obstruction, and prevent recurrence.

Initial Medical Management

In cases of acute cholangitis, early intervention is crucial:

• Hospital Admission – most patients require hospitalisation for close monitoring, and supportive care.
• Intravenous (IV) Antibiotics – broad-spectrum antibiotics are started immediately to control the infection. These may be adjusted based on blood culture results.
• Fluid Resuscitation and Supportive Care – IV fluids, pain control, and nutritional support are provided as needed to stabilise the patient.

Biliary Drainage and Definitive Treatment

Once the patient is stabilised, the next step is to relieve the obstruction in the bile duct:

• ERCP – this is the preferred method for bile duct drainage. During ERCP, the doctor can remove bile duct stones, place a stent or perform a sphincterotomy to improve bile flow.
• Percutaneous Transhepatic Biliary Drainage (PTBD) – if ERCP is not feasible, especially in altered anatomy or critically ill patients, PTBD may be used to drain bile externally.
• Surgical Intervention – rarely, surgery may be required in cases of failed endoscopic drainage or in patients with strictures, tumours or anatomical anomalies.

Ongoing Management and Prevention

After recovery, further evaluation and long-term management may be needed to prevent recurrence:

• Cholecystectomy – gallbladder removal may be recommended in patients with gallstone-related cholangitis to prevent future episodes.
• Monitoring for Underlying Conditions – if strictures, tumours or chronic liver conditions like PSC are identified, long-term follow-up, and targeted treatment are essential.
• Lifestyle Modifications – maintaining a healthy weight, managing diabetes or cholesterol, and avoiding alcohol may support liver, and biliary health.

Summary

Cholangitis can become life-threatening if not treated promptly. If you are experiencing symptoms like abdominal pain, fever or yellowing of the skin or eyes, it is important to seek medical attention early. It is important to remember that timely diagnosis, and treatment can prevent serious complications, and safeguard your liver health.

At Dr Lee Chin Li’s clinic, we offer expert evaluation, and modern diagnostic tools to help you get the answers and care you need. So, book your consultation today, and take the first step toward better biliary health.

Is cholangitis painful?

Yes. Patients with cholangitis often report moderate to severe pain in the right upper abdomen. The pain may radiate to the right shoulder or back and is typically accompanied by fever, and chills. It is usually sharp and persistent, not relieved by rest or over-the-counter medications.

Is cholangitis life-threatening?

Yes, cholangitis can become life-threatening if not treated quickly. The infection can spread from the bile ducts to the bloodstream, resulting in sepsis, which may cause organ failure. That is why early diagnosis, and treatment are important as they significantly reduce this risk.

How does cholangitis impact your quality of life?

An acute episode of cholangitis can lead to:

• Hospitalisation, and time away from work or family
• Fatigue, weakness, and prolonged recovery
• Increased anxiety about recurrent infections or complications
• In some cases, the need for long-term stents or repeat procedures

Is surgery always necessary for cholangitis?

No. In most cases, ERCP is sufficient to relieve the blockage. Surgery is considered only when endoscopic or radiological drainage is not effective or feasible. Surgery for gallbladder is recommended in gallstone cause of cholangitis after drainage of bile duct and stabilisation of patient.

How long does recovery take after cholangitis treatment?

Most patients recover within a few days to 2 weeks, depending on severity. Some may require additional procedures or follow-up care.

Can cholangitis come back?

Yes. Recurrent cholangitis can occur, especially in people with unresolved ductal obstruction, strictures, or permanent stents. Additionally, long-term management and regular imaging are essential.

Can I prevent cholangitis?

You can reduce your risk by:

• Managing gallstones early
• Treating bile duct narrowing promptly
• Attending regular follow-ups if you have a biliary stent or chronic liver condition

Does diet affect cholangitis?

While diet does not directly cause or cure cholangitis, a low-fat, balanced diet can reduce gallstone formation and support liver health, especially after recovery.

Who is at risk of Cholecystitis in Singapore?

Cholecystitis can affect individuals of all ages, but certain health, hormonal, and lifestyle factors can increase the likelihood of gallbladder inflammation. In Singapore, the following groups may be at greater risk of developing acute or chronic cholecystitis:

• Age — the risk of cholecystitis rises with age, particularly in individuals over 40 years old. With advancing age, gallbladder motility tends to decline, and the risk of gallstone formation increases, both of which contribute to gallbladder inflammation.
• Gender — women are more likely to develop cholecystitis, especially during their reproductive years. This is largely due to hormonal influences, such as oestrogen, and progesterone, which can affect bile composition and gallbladder function.
• Chronic illness — conditions such as diabetes, liver disease or spinal cord injury can impair gallbladder motility or immune function, making the gallbladder more susceptible to infection, and inflammation.
• Infections and systemic illness — acute cholecystitis can occasionally develop without gallstones (acalculous cholecystitis), particularly in those with severe infections, trauma, or sepsis, where the gallbladder becomes inflamed due to reduced blood flow or bile stasis.
• Gallstones — having gallstones is the most common cause of cholecystitis. When a stone blocks the cystic duct, it can lead to bile buildup, and gallbladder irritation, often triggering acute inflammation.
• Previous episodes of gallbladder disease — individuals who had biliary colic or mild gallbladder inflammation in the past are at increased risk of recurrent or chronic cholecystitis.
• Pregnancy or hormone therapy — hormonal fluctuations during pregnancy or from the use of oral contraceptives and hormone replacement therapy can increase bile cholesterol levels and slow gallbladder emptying, raising the risk of gallstone-related cholecystitis.
• Obesity and metabolic syndrome — excess body weight, insulin resistance, and high cholesterol can disrupt normal bile composition, promoting gallstone formation, and subsequent inflammation.
• Rapid or extreme weight loss — very low-calorie diets or post-bariatric surgery weight loss can lead to cholesterol supersaturation in bile, encouraging gallstone formation, and increasing the risk of cholecystitis.
• Fasting or prolonged intravenous feeding — lack of food intake reduces gallbladder contractions, allowing bile to stagnate. This can increase the risk of stone formation, and gallbladder inflammation, particularly in hospitalised or critically ill patients.

What are the treatment options for Cholecystitis in Singapore?

Treatment depends on the fitness of patient and overall health. In most cases, hospitalisation, and pain control are recommended first. Surgical intervention is typically required in symptomatic cases or in cases with complications.

Non-Surgical Treatment

Non-surgical treatment is the initial step in managing suspected acute cholecystitis, especially if there is ongoing investigations to confirm the diagnosis.

• Hospital Admission – patients with suspected cholecystitis are usually admitted for close monitoring, intravenous fluids, and pain management.
• Antibiotics – broad-spectrum antibiotics are administered in patient with fever and clinical suspicion of acute cholecystitis.
• Pain Relief – analgesics are provided to manage abdominal pain, and discomfort. Non-opioid or opioid medications may be used depending on severity.
• Bowel Rest – patients are advised to avoid eating or drinking temporarily to reduce gallbladder stimulation, and allow inflammation to subside.
• Nutritional Support – intravenous fluids, and electrolytes are given to maintain hydration, and nutrition during the fasting period.

Surgical Treatment

Surgical removal of the gallbladder (cholecystectomy) is the definitive treatment for most cases of cholecystitis, especially when gallstones are involved.

• Laparoscopic Cholecystectomy – this is the most common surgical procedure. It involves small incisions, and a camera-guided removal of the gallbladder. Recovery is typically quicker, with less pain and a lower risk of complications.

• Open Cholecystectomy – in more severe cases or if there are complications like gangrene, perforation or extensive scarring, open surgery may be necessary.

• Percutaneous Cholecystostomy – for patients who are too ill to undergo surgery, a temporary drainage tube may be placed into the gallbladder to relieve pressure, and infection until they are stable enough for surgery.

Long-Term Management and Prevention

Once recovered, further steps may be recommended to ensure recovery from the inflammation:

• Maintain a healthy body weight.
• Adopt a balanced, low-fat diet to minimise gallstone formation.
• Monitor, and manage chronic conditions such as diabetes or high cholesterol.
