Liver Cirrhosis and Colonoscopies: What You Need to Know About Bleeding Risks

Reese Marlowe in Health & Wellness November 2025 • 4 min read.

"A new study sheds light on the increased risk of immediate bleeding after colonoscopies in patients with advanced liver cirrhosis, emphasizing the need for careful evaluation and management."

Colorectal cancer is a significant health concern worldwide, ranking as the third most common cancer and the second leading cause of cancer-related deaths. Colonoscopies have emerged as a vital tool in screening for colorectal neoplasms, allowing for the early detection and removal of potentially cancerous polyps.

Colonoscopic polypectomy, the procedure to remove these polyps, has been proven to reduce both the incidence and mortality of colorectal cancer. While generally safe, colonoscopies are not without risks. Bleeding, perforation, and even death can occur, with post-polypectomy bleeding (PPB) being a relatively common complication.

For individuals with liver cirrhosis, undergoing a colonoscopy adds another layer of complexity. Liver cirrhosis, a chronic condition characterized by scarring of the liver, can disrupt normal blood clotting processes, potentially increasing the risk of bleeding during and after medical procedures. A recent study published in the Yonsei Medical Journal has investigated this specific risk, providing valuable insights for both doctors and patients.

Decoding the Bleeding Risk: What the Study Revealed

The Yonsei Medical Journal study aimed to evaluate the risk of immediate post-polypectomy bleeding (IPPB) in patients with liver cirrhosis undergoing colonoscopic polypectomy. The researchers compared 89 patients with liver cirrhosis to a control group of 348 individuals without liver disease. Key findings highlighted a significantly increased incidence of IPPB in cirrhotic patients with Child-Pugh class B or C (more advanced stages of cirrhosis) compared to those with Child-Pugh class A (less severe cirrhosis) or the control group.

Specifically, the study identified several factors that independently increased the risk of IPPB:

Advanced Cirrhosis (Child-Pugh Class B or C): Patients with more severe liver cirrhosis had a 3.5 times higher risk of immediate bleeding.
Large Polyps: Polyps larger than 10mm in size were associated with a 3.6 times increased risk.
Pedunculated Polyps: These polyps, which have a stalk-like structure, carried a 2.4 times higher risk compared to non-pedunculated polyps.

These results underscore the importance of assessing the severity of liver disease and polyp characteristics before performing a colonoscopy in patients with cirrhosis. The study emphasizes that while liver cirrhosis itself may not be an absolute contraindication for colonoscopy, the presence of advanced cirrhosis (Child-Pugh B or C) necessitates extra caution.

Making Informed Decisions: What This Means for You

If you have liver cirrhosis and are scheduled for a colonoscopy, it's crucial to have an open and honest conversation with your doctor. Discuss your Child-Pugh score (if known) and any concerns you may have about bleeding risks. Your doctor may recommend additional precautions, such as closer monitoring during the procedure or alternative polyp removal techniques. Remember, proactive communication and a thorough understanding of your individual risk factors are key to ensuring a safe and successful colonoscopy.

Everything You Need To Know

What is liver cirrhosis, and why does it matter when considering medical procedures?

Liver cirrhosis is a chronic condition where the liver becomes scarred, disrupting its normal functions, including blood clotting. This is important because it can increase the risk of bleeding during medical procedures like colonoscopies. The severity of liver cirrhosis is often classified using the Child-Pugh classification, with class A being less severe and classes B and C indicating more advanced stages. This classification is clinically significant because individuals with Child-Pugh class B or C cirrhosis face a higher risk of immediate post-polypectomy bleeding (IPPB). Understanding the implications of liver cirrhosis on blood clotting helps doctors take necessary precautions during colonoscopies to minimize potential complications.

What is a colonoscopy and why is it performed?

A colonoscopy is a procedure where a doctor uses a long, flexible tube with a camera to examine the inside of the colon and rectum. It's significant because it's a primary method for screening colorectal neoplasms, allowing for the detection and removal of potentially cancerous polyps. Colonoscopies play a crucial role in reducing both the incidence and mortality of colorectal cancer. The implications of colonoscopies extend to post-polypectomy bleeding (PPB), a potential complication where bleeding occurs after the removal of polyps during the procedure, especially in individuals with conditions like liver cirrhosis.

What is post-polypectomy bleeding, and why is it a concern?

Post-polypectomy bleeding (PPB) refers to bleeding that occurs after a polyp is removed during a colonoscopy. It is important because it is a relatively common complication of colonoscopies. In the context of liver cirrhosis, the risk of immediate post-polypectomy bleeding (IPPB) is especially significant because cirrhosis can impair the body's ability to clot blood. The *Yonsei Medical Journal* study highlights that patients with advanced liver cirrhosis (Child-Pugh class B or C) are at a higher risk of IPPB, emphasizing the need for careful evaluation and management during colonoscopies in these individuals.

What is the Child-Pugh classification, and how does it relate to bleeding risks?

The Child-Pugh classification is a system used to assess the severity of liver cirrhosis, categorizing it into classes A, B, and C. It's significant because it helps doctors understand the extent of liver damage and predict potential complications. The *Yonsei Medical Journal* study revealed that patients with Child-Pugh class B or C cirrhosis have a significantly higher risk of immediate post-polypectomy bleeding (IPPB) compared to those with class A. The implication is that the Child-Pugh score should be carefully considered when planning a colonoscopy for patients with liver cirrhosis to manage bleeding risks effectively.

What is colonoscopic polypectomy, and what factors increase the risk of bleeding during this procedure?

Colonoscopic polypectomy is the procedure to remove polyps during a colonoscopy. It is important because removing polyps reduces the risk of colorectal cancer. The *Yonsei Medical Journal* study noted that certain polyp characteristics, such as large polyps (greater than 10mm) and pedunculated polyps (polyps with a stalk-like structure), are associated with a higher risk of immediate post-polypectomy bleeding (IPPB). The implication is that doctors need to be particularly cautious when performing colonoscopic polypectomy on patients with these types of polyps, especially if they also have liver cirrhosis.
