What are Biliary Disorders?
Biliary disorders are conditions that affect the gallbladder and bile ducts, the system that carries bile from the liver to the small intestine. The most common are gallstones, gallbladder inflammation (cholecystitis), bile duct blockages, and chronic bile duct diseases such as primary biliary cholangitis. At United Gastroenterology Associates, Dr. Muhammad Ali Khan evaluates and manages biliary conditions at offices in Cypress and Katy, TX.
Biliary disorders refer to a range of conditions that affect the bile ducts, gallbladder, and liver. Bile is essential for digestion, helping to break down fats in the small intestine. When there are issues with bile production, flow, or storage, it can lead to serious health problems, including pain, inflammation, and infection. Common biliary disorders include gallstones, biliary tract infections, bile duct obstructions, and primary biliary cholangitis.
At United Gastroenterology Associates, we take a comprehensive approach to diagnosing and treating biliary disorders. Our team uses advanced diagnostic techniques and personalized treatment plans to help relieve symptoms, address the underlying cause, and prevent complications.

Common Biliary Disorders We Treat
Dr. Khan evaluates and manages the following gallbladder and bile duct conditions in adults and coordinates with surgeons when gallbladder surgery is needed.
Gallstones
Hard deposits that form in the gallbladder and can block the bile ducts, causing severe pain, nausea, and digestive issues.
Cholecystitis
Inflammation of the gallbladder, often caused by gallstones, leading to intense pain and infection.
Bile Duct Obstruction
Blockages in the bile ducts, which can prevent bile from flowing from the liver to the intestines.
Primary Biliary Cholangitis (PBC)
A chronic liver disease where the bile ducts are slowly destroyed, leading to bile buildup and liver damage.
Sclerosing Cholangitis
A condition that causes scarring and narrowing of the bile ducts, leading to liver damage.
Gallstone Pancreatitis
Inflammation of the pancreas caused by a gallstone blocking the shared bile and pancreatic duct.
Symptoms of Biliary Disorders
Gallbladder pain often starts in the upper right or middle of the abdomen, may spread to the right shoulder or back, and can follow a fatty meal. Some biliary conditions cause no symptoms and are found on blood tests or imaging.
If you are experiencing these symptoms, it’s important to seek medical care for a proper diagnosis and treatment plan.
When to seek emergency care
Call 911 or go to the nearest emergency room for severe abdominal pain lasting several hours, pain with fever and chills, or yellowing of the skin or eyes with confusion.
Common symptoms of biliary disorders
- Severe abdominal pain, especially in the upper right side
- Jaundice (yellowing of the skin and eyes)
- Nausea and vomiting
- Fever and chills
- Dark urine and pale stools
- Unexplained weight loss or fatigue
- Itching (pruritus)
A symptom alone does not confirm a diagnosis. Symptoms should be evaluated by a qualified medical professional.
Gallbladder or Bile Duct Symptoms?
Recurring upper abdominal pain, jaundice, or abnormal liver tests should be evaluated. Dr. Khan sees patients at the Cypress and Katy offices.
Biliary Disorder Treatment Options
Treatment depends on the condition and whether a stone or blockage is present. The goals are to relieve symptoms, clear blocked ducts, protect the liver, and prevent infection and pancreatitis.
Diagnostic Testing
Testing may include ultrasound, endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiopancreatography (MRCP), and blood tests to accurately diagnose biliary conditions.
Medication Management
Depending on your condition, medications may be prescribed to manage pain, reduce inflammation, or dissolve gallstones.
Endoscopic Procedures
For conditions such as bile duct obstruction or gallstones, endoscopic procedures like ERCP may be performed to remove blockages or stones.
Surgical Interventions
In severe cases, surgery such as cholecystectomy (removal of the gallbladder) or bile duct surgery may be required. Dr. Khan coordinates with surgical specialists when surgery is needed.
Lifestyle and Dietary Changes
Managing a biliary disorder often involves changes to your diet and lifestyle. We provide guidance on dietary adjustments that can help prevent further complications, such as reducing fatty food intake and increasing fiber-rich foods.

Frequently Asked Questions About Biliary Disorders
Answers to common questions about gallbladder and bile duct conditions.
What is the difference between the gallbladder and the bile ducts?
The gallbladder is a small organ under the liver that stores bile. The bile ducts are tubes that carry bile from the liver and gallbladder to the small intestine.
Do gallstones always need treatment?
No. Gallstones that cause no symptoms often do not need treatment. Gallstones that cause pain, inflammation, or blockages usually need treatment, often gallbladder removal.
What is ERCP?
ERCP (endoscopic retrograde cholangiopancreatography) uses an endoscope and X-ray to examine and treat the bile and pancreatic ducts, for example to remove stones or place a stent. Learn about ERCP.
What is primary biliary cholangitis (PBC)?
PBC is a chronic autoimmune disease in which the small bile ducts in the liver are slowly damaged. It is usually treated with medicine that improves bile flow and is monitored with regular blood tests.
What are the warning signs of a blocked bile duct?
Yellowing of the skin or eyes, dark urine, pale stools, itching, and upper abdominal pain can signal a blockage. Pain with fever and chills needs emergency care.
How are biliary disorders diagnosed?
Diagnosis may include liver blood tests, abdominal ultrasound, MRCP, and ERCP or endoscopic ultrasound when needed.
