While colonoscopies are a standard medical procedure, colonoscopy errors can still occur. While some of these errors might be foreseeable, they may be due to a provider’s failure to uphold the standard of care expected of them.
If you are suffering from signs of colonoscopy complications and believe your injuries were avoidable, the medical professionals involved in your procedure might have committed medical malpractice.

Key Takeaways: Colonoscopy Complications in Maryland
- Colonoscopy complications can include perforation, bleeding, infection, anesthesia reactions, and post-procedure complications that may appear right away or days later.
- Not every complication means malpractice—but avoidable harm may point to a failure to follow the standard of care, poor monitoring during sedation, or negligent post-procedure response.
- Documentation matters: procedure notes, anesthesia records, follow-up instructions, ER visits, imaging, and a clear symptom timeline often drive case clarity.
- A consultation can help you understand whether the complication was a known risk or a preventable error and what evidence is needed in Maryland.
If Something Felt “Off” After Your Colonoscopy, Trust That Instinct
Many people end up here because they were told the procedure was routine—then the pain, bleeding, fever, or ER trip happened. When you’re suffering colonoscopy complications in Maryland, the hardest part is not knowing whether it was an unavoidable risk or an avoidable error. You deserve clear answers and a process that takes your experience seriously.
What Is a Colonoscopy?
A colonoscopy is one of the main diagnostic tests for colon cancer and involves an examination of the inner lining of your large intestine and rectum.
Colonoscopies are routinely recommended for patients aged 50 or over or for individuals suffering from constipation, diarrhea, pain in the abdomen, or rectal bleeding. While this is a routine procedure, it does not mean that colonoscopy errors do not occur.
How Long After a Colonoscopy Can Complications Arise?
Colonoscopy complications most frequently occur immediately following the procedure. However, it is not uncommon for complications to arise within the first few days after your procedure and, in rare cases, they can occur 1-2 weeks after your colonoscopy.
What Types of Injuries Can Complications from a Colonoscopy Cause?
Because colonoscopies involve sedation and the insertion of a tube or camera into the body, there is some risk of injury.
If your gastroenterologist fails to evaluate your risk factors before a colonoscopy, the likelihood of complications can increase. Some of the most common complications from a colonoscopy include the following.
1. Perforation of the Colon
Perforation of the colon can occur if doctors are not careful with the colonoscope. If your colon is perforated, the contents of your intestine can leak into your abdominal cavity.
This leakage is the most severe complication, as it can cause sepsis or long-term damage and requires surgical intervention to correct.
Post-polypectomy electrocoagulation syndrome can also cause colon perforation. This process involves removing polyps using electrical energy to burn them off the colon walls.
2. Bleeding
Bleeding can occur if the colon is perforated, but it is also a likely complication of removing polyps or taking a biopsy. Depending on the severity of the bleeding, surgical treatment may be necessary and can cause lasting damage.
3. Infection
You might suffer an infection if bacteria from the colon or large intestine enter the bloodstream through a perforation during a colonoscopy. There is also a chance that infection can occur if your medical provider fails to use properly sterilized equipment.
4. Complications from Anesthesia
Possible reactions to anesthesia can range from mild to life-threatening. An example of a mild reaction is taking longer to wake up than is normal, which could cause low blood pressure. More severe reactions to anesthesia include allergies, high blood pressure, arrhythmia, and heart attack.
5. Complications from Existing Medical Conditions
If you already suffer from heart or lung disease, you are at a greater risk of complications during other medical procedures. If your doctors fail to consider your risk factors, this could be medical malpractice.
A Simple Symptom Timeline Can Change Everything
Write down when your symptoms started, how they progressed, and when you sought help—especially if you returned to the ER or were admitted. Save discharge instructions, follow-up messages, and any imaging or lab results you received. This timeline often makes it easier to see whether the response after your colonoscopy was timely and appropriate.
When Is a Colonoscopy Error Medical Malpractice?
Not all colonoscopy complications are the result of medical malpractice. Malpractice occurs when a healthcare provider fails to follow the same standard of care that other providers with similar experience and background would use, and their failure causes a patient to suffer injury and damage.
A breach of the standard of care can result from either an action or a failure to act.
Two common ways healthcare providers breach their standard of care during a colonoscopy are:
- Failure to monitor. Medical personnel involved in a colonoscopy are responsible for monitoring vital signs and reactions to anesthesia. Failure to notice or react to distress can lead to long-term complications, including increased blood pressure or heart attack, that are typically avoidable when patients are appropriately monitored.
- Negligent postoperative care. Ignoring or misinterpreting symptoms after the procedure is complete can lead to greater injury, especially in the case of a perforated bowel or internal bleeding. If medical professionals fail to act with reasonable urgency in postoperative care, long-term injury can increase.
If you suffer signs of colonoscopy complications, don’t wait to contact an attorney. In Maryland, you have only five years from when the injury occurred or three years from when you discovered the injury to file your claim.
What Damages Can You Recover in a Medical Malpractice Claim?
There are two types of damages generally available in medical malpractice claims: economic damages and non-economic damages. Economic damages are measurable harms.
These include medical costs like hospital bills, in-home care expenses, and medical accessories. Economic damages also include wages lost while you’re recovering from injury, and can consist of lost earning potential if you cannot return to the same line of work.
Non-economic damages are intangible losses that can be harder to calculate. They include things like pain and suffering caused by the injury and loss of enjoyment of life. Since these damages are intangible, Maryland caps the total recovery amount for non-economic damages.
For an injury occurring in 2024, the cap for noneconomic damages is $890,000.

FAQ: Colonoscopy Complications in Maryland (MD)
If you are experiencing colonoscopy complications in Maryland, these FAQs explain common injuries, warning signs, and when a “known risk” may cross the line into medical malpractice.
Common colonoscopy complications include colon perforation, bleeding (often after polyp removal or biopsy), infection, anesthesia reactions, and post-procedure complications that can worsen if symptoms are ignored or misread. Serious complications are uncommon overall, but they can be life-changing when they occur.
Some complications appear immediately, but others can develop over the next few days. In certain situations, symptoms may show up later—especially when bleeding or post-polypectomy issues develop after you’ve already gone home.
Severe or worsening abdominal pain, fever, chills, rapid heart rate, fainting, confusion, or signs of infection can be red flags. Perforation can allow bacteria and intestinal contents to escape into the abdomen, which can become an emergency.
Some bleeding can occur, especially after polyp removal or biopsy. Bleeding that is heavy, persistent, causes weakness or dizziness, or leads to an ER visit may indicate a significant complication that needs urgent evaluation and can raise questions about technique and post-procedure care.
Infection can occur if bacteria enter the bloodstream through an injury to the bowel wall, or if equipment is not properly sterilized. Fever, chills, increasing abdominal pain, and worsening symptoms after discharge should be taken seriously.
Anesthesia complications can range from delayed waking and blood pressure issues to more serious cardiovascular or breathing problems. Monitoring is critical—failures to observe and respond to distress can turn a manageable issue into a severe injury.
Post-polypectomy syndrome can occur after removal of polyps using cautery/electrical energy. It can mimic perforation symptoms (pain, fever, inflammatory signs) and may require urgent evaluation to rule out more dangerous injuries.
Not all complications are malpractice. It may become malpractice when avoidable harm occurs because the provider failed to meet the standard of care—such as failing to evaluate risk factors, using poor technique, failing to monitor during sedation, or providing negligent postoperative care when symptoms appear.
Helpful records often include the colonoscopy report, procedure and polyp removal notes, pathology results, anesthesia records, vital sign monitoring logs, discharge instructions, post-procedure calls, ER/hospital records, imaging (CT), labs, and a clear symptom timeline.
Depending on the case, compensation can relate to medical bills, additional surgeries, rehabilitation, time missed from work, future care needs, and the personal impact of pain, limitations, and loss of normal life. The key is connecting the complication to avoidable error and resulting harm.
