Understanding Elevated Liver Enzymes After Gallbladder Removal Surgery
Gallbladder removal surgery, also known as cholecystectomy, is a very common procedure performed to treat gallstones and gallbladder disease. Over 700,000 cholecystectomies are performed every year in the United States alone. While generally safe, like any surgery, gallbladder removal does carry potential complications. One such complication that may arise is elevated liver enzymes after the procedure.
What Causes Elevated Liver Enzymes After Gallbladder Surgery?
The liver produces important enzymes that are released into the bloodstream. When the liver is injured or inflamed, more of these liver enzymes leak out and levels become elevated on blood tests. There are a few reasons this may happen after a cholecystectomy:
- Bile duct injury - The bile ducts carry bile from the liver and gallbladder. If a bile duct is accidentally clipped, cut or removed during gallbladder removal surgery, bile can leak out into the surrounding tissues causing inflammation and elevated liver enzymes.
- Retained stones - Gallstones may occasionally be left behind and fall into bile ducts after the gallbladder is removed. These can cause backup of bile, inflammation, and elevated liver enzyme levels.
- Other complications - Issues like bile leaks or bleeding into the liver during or after surgery can also lead to elevated liver enzymes.
Significance of Elevated Liver Enzymes After Cholecystectomy
Mild elevations in liver enzymes after gallbladder removal surgery are common and often temporary. However, significant and persistent elevations, especially with bilirubin, could indicate a major bile duct injury or bile flow obstruction. This would require prompt investigation and treatment to prevent serious complications like infection, liver failure, or the need for further surgery. Seeking urgent medical care is advised if you have yellowing eyes or skin, fever, abdominal pain, vomiting, clay/grey stool, or worsening liver test results after a cholecystectomy.
Evaluating Elevated Liver Enzymes After Gallbladder Removal
If liver enzymes are found to be elevated on blood tests after a cholecystectomy, further evaluation is needed. This typically includes some combination of the following tests:
Blood Tests
Blood tests assessing liver enzyme levels are repeated multiple times to look for trends. Additional blood tests measure bilirubin levels, liver synthetic function, and markers of infection when concerned about potential bile duct injury. These help determine the cause and severity of any liver issues.
Diagnostic Imaging
- Ultrasound - Ultrasound is usually the first imaging test ordered to evaluate the liver, bile ducts, and surrounding anatomy after gallbladder removal surgery. It may detect retained stones, fluid collections, or leakage.
- HIDA scan - HIDA scans assess bile flow from the liver and can diagnose bile leaks or obstructions.
- MRCP or ERCP - MRCP provides detailed imaging of bile ducts non-invasively, while ERCP combines x-ray imaging with contrast injection into bile ducts allowing treatment at the same time.
- CT scan - CT imaging gives the detailed views of the liver necessary to provide additional information about potential complications.
Treating Elevated Liver Enzymes After Cholecystectomy
The approach to managing elevated liver enzymes after gallbladder removal depends on the underlying cause, which the above evaluation seeks to determine. Here are the main treatment approaches:
Monitoring and Supportive Care
When mild transient enzyme elevations are expected to resolve on their own, monitoring blood tests and providing supportive care are all that's needed initially. This allows time for the body to heal without intervention. Hospitalization for close observation may be required if enzyme or bilirubin levels continue to rise despite conservative measures or infection develops.
Medications and Supplements
Medications that help reduce bile flow may be used short-term if a bile leak is suspected after gallbladder removal surgery. Antibiotics are also administered if any sign of infection emerges. Vitamin supplements making up for reduced bile absorption are occasionally prescribed if diarrhea results from bile salt malabsorption.
Surgery and Procedures
If major bile duct injury, bile duct obstruction from retained stones, leak, or stricture occurs after initial gallbladder removal, additional procedures are required. This may involve stent placement, balloon dilation, stone extraction via ERCP, or corrective bile duct surgery to repair anatomical defects and restore normal bile flow between liver, bile ducts, and intestines.
Preventing Elevated Liver Enzymes After Cholecystectomy
While some post-cholecystectomy liver enzyme elevation cannot be prevented entirely, the following measures aim to minimize risk:
- Choosing an experienced, high-volume biliary surgeon at a center of excellence can make the procedure safer by avoidingerrors leading to complications.
- Following surgery instructions carefully, including wound care, diet, medication, and activity modifications in the recovery period.
- Promptly seeking medical attention for concerning signs and symptoms such as fever, jaundice, blood in stool, uncontrolled pain, vomiting, etc. can help address issues early.
- Attending all follow-up appointments for bloodwork monitoring and imaging tests allows the surgical team to catch potential problems sooner.
In cases of uncomplicated laparoscopic cholecystectomy, over 90% of patients recover smoothly without elevated liver enzymes or other issues. However, it remains vital to monitor for post-operative complications that may warrant additional treatment. Consulting your doctor is essential for interpreting test results and determining suitable next steps.
