signs that a surgeon left a foreign object in body after surgery

That a surgeon would leave something in your body sounds like something you hear only on investigative news shows. But it happens—and more often than you probably think.

If you’ve undergone recent surgery, learning more about potential warning signs of a foreign object is crucial. You want to know these signs and seek additional medical treatment before it becomes a life-threatening condition.

The type of objects left in the body after surgery can vary widely. 

Objects left in the body after surgery, called retained surgical items (RSIs), are serious medical errors. Common RSIs include sponges, clamps, or instrument fragments. These can cause infection, internal damage, or chronic pain. Prompt diagnosis, removal, and legal consultation are critical if an RSI is suspected.

Warning Signs of Objects Left in a Body After Surgery

Foreign objects left in the body are often called retained surgical bodies (RSB) or unintended retained foreign objects (URFO). Depending on the circumstances, symptoms of a foreign object left in the body after surgery could appear immediately, weeks, months, or even years later. 

There’s a risk of death with some foreign objects, so it’s crucial to understand what to look for after surgery. Signs include: 

  • Trouble urinating;
  • Constipation;
  • Bloody, black, or tar-like stools;
  • Tenderness or swelling near the surgical site;
  • Fever;
  • Severe and recurring headaches;
  • Severe pain around or near the surgical site;
  • Coughing up or vomiting blood;
  • Seepage near the surgical site;
  • Severe pain in your leg;
  • Difficulty with basic bodily functions such as eating, breathing, and swallowing;
  • Unexplained weight loss;
  • Swollen lymph nodes;
  • Streaks near the incision;
  • Numbness in the feet or hands;
  • Unpleasant odor coming from the incision site;
  • Difficulty keeping liquids or food down, even if you’re hungry;
  • Abscess or fistula forming; and
  • An overall decline in your health. 

If you have any symptoms following surgery, please immediately speak with a doctor. The longer you wait, the higher the risk of complications.

Complications from Foreign Object Left in Body: What Can Go Wrong?

Leaving a foreign object in the body after surgery can have devastating consequences. In addition to pain and infection, these retained objects can cause bowel obstructions, organ perforation, abscesses, and sepsis—a life-threatening immune response. According to the National Institutes of Health (NIH), retained surgical items occur in approximately 1 out of every 5,500 to 7,000 surgeries in the United States, but experts believe the real number may be higher due to underreporting.

The complications from a foreign object left in body cases vary depending on the type and location of the object, but all require swift medical attention. If you suspect something is wrong, don’t delay in getting a second opinion or requesting imaging tests such as an X-ray, MRI, or CT scan.

What Are the Risks of a Surgical Instrument Left Inside a Patient?

Post-surgery, if a foreign object (like a surgical sponge) is unintentionally left inside a patient’s body, it can lead to long-term issues. These objects might trigger aseptic inflammation or exudation without an infection, causing persistent pain or discomfort over months or years.

Metal Left in Body After Surgery

A retained object, such as a metal clip left in the body after surgery, is medical malpractice. Retained objects cause serious complications, including infection, organ damage, and chronic pain.

Retained Foreign Object and New Mexico Medical Malpractice Laws

Under New Mexico law, you generally have three years from the date of the alleged malpractice to file a lawsuit. However, in cases involving a foreign object left in the body after surgery, the clock may not start ticking until the patient discovers—or reasonably should have discovered—the issue. This exception is known as the “discovery rule.”

Because each case is different, consulting with a medical malpractice attorney who understands how New Mexico applies the discovery rule in retained foreign object cases is critical.

Can You File a Lawsuit Against the Responsible Parties?

Yes, but filing a foreign object left in the body after a surgery lawsuit is complicated. You need a skilled lawyer on your side who can walk you through the process and protect your rights. You have the right to pursue compensation for your injuries and other damages. If your case is successful, you can receive compensation for the following: 

  • Your medical expenses;
  • Future expected medical costs;
  • Lost wages and loss of earning capacity;
  • Pain and suffering; and
  • Mental anguish.

Your attorney will help you calculate your potential case value and let you know what damages you’re eligible to receive. 

The swelling, the infections, the strange pain—this wasn’t supposed to happen. If you're worried something went wrong during surgery, you may be right. Let Poulos & Cavazos investigate and guide you toward the justice you deserve. Contact Us

Why It’s So Important to Act Quickly

Delaying action when you suspect a foreign object left in the body after surgery can significantly increase your health risks. The longer a retained item stays inside your body, the more likely it is to cause irreversible damage—especially if it leads to infection, internal bleeding, or damage to nearby organs.

Taking action quickly helps preserve evidence. If you later pursue a medical malpractice case, documentation such as scans, treatment notes, and communication with doctors can strengthen your claim. A trusted legal team like Poulos & Cavazos can help ensure that every step you take supports both your health and your potential case.

Foreign Object Left in Body After Surgery FAQs in New Mexico

1. What does it mean if a foreign object was left in the body after surgery?

A foreign object left in the body after surgery is often called a retained surgical item. It can include surgical sponges, gauze, clamps, needles, or fragments of medical devices that were not removed before the incision was closed. Retained items can trigger infection, pain, and serious postoperative complications.

2. What are the warning signs a surgeon left something inside your body?

Common warning signs include persistent or worsening pain, swelling, redness, fever, foul-smelling drainage, a surgical wound that won’t heal, nausea, or unexplained fatigue. Some patients also develop a painful lump, abscess, or signs of internal infection after surgery.

3. How long after surgery can symptoms of a retained surgical sponge or tool appear?

Symptoms can appear within days, but they may also show up weeks or months later—especially when the body forms inflammation, scar tissue, or an abscess around the retained object. If recovery is not progressing normally, it is reasonable to ask whether imaging is needed to rule out a retained item.

4. What complications can a foreign object left in the body cause?

Retained objects can lead to infection, sepsis, internal bleeding, bowel obstruction, organ perforation, chronic pain, nerve irritation, and additional surgeries. In severe cases, complications can become life-threatening if the issue is not identified and treated quickly.

5. How is a retained surgical item diagnosed?

Doctors may use X-rays, CT scans, ultrasound, or MRI depending on the surgical area and the suspected object. Surgical records, sponge counts, and operative notes can also help determine whether an item was missing or whether the surgical team documented any complications.

6. Is leaving a foreign object inside a patient always malpractice?

Retained surgical items are generally considered preventable and often raise serious safety concerns. Whether a specific case qualifies depends on what the records show, how the counting and verification procedures were handled, and whether the retained item caused measurable harm requiring treatment, hospitalization, or additional surgery.

7. Who may be responsible—the surgeon, the hospital, or the surgical team?

Responsibility may involve the surgeon, operating room staff, and the hospital or surgical facility. These cases often focus on operating room protocols, sponge and instrument counts, communication during the procedure, and whether safety systems were followed before closing the incision.

8. What should I do if I suspect a foreign object was left in my body?

Seek medical care promptly—especially if you have fever, severe pain, drainage, or a wound that is not healing. Request your surgical and hospital records, and keep a timeline of symptoms, follow-up visits, imaging, and any additional treatment. Early diagnosis can reduce the risk of serious infection or complications.

9. What compensation may be available for a retained surgical item case in New Mexico?

Compensation may include medical bills, costs of additional surgery, hospitalization, rehabilitation, lost wages, reduced earning capacity, and pain and suffering. Serious complications such as sepsis, organ damage, or long-term disability can significantly increase damages.
