Chicago Surgical Error Lawyers Offering Focused Representation After Devastating Surgical Mistakes

Last updated on March 19, 2026

Surgery often starts with hope for relief or recovery. When a surgeon or hospital makes a preventable mistake, you may face repeat procedures, infection, permanent disability or loss of life. At Dudley & Lake, we listen with care, we explain the path forward in plain terms and we pursue accountability with the resources these cases demand.

For more than two decades, we have built our reputation across Illinois through careful preparation, respected trial work and a history of results in serious medical malpractice cases. From our Libertyville and Peoria offices, we serve injured patients statewide.

Surgical Mistakes Are Often Preventable

A surgical error involves a preventable mistake before, during or after an operation that harms the patient. These cases often involve breakdowns in planning, communication, training or safety checks.

Surgical errors can take many forms, and each one can create serious complications and a long recovery time. Common issues include:

• Anesthesia mistakes: An anesthesia provider gives the wrong drug or dose, or manages the airway poorly, which can lead to brain injury, cardiac events or awareness during surgery.
• Artery or nerve damage: A surgical mistake injures a major blood vessel or nerve and can lead to severe bleeding, loss of function or chronic pain.
• Defective implants: A faulty medical implant fails or causes complications, which may require revision surgery and long-term treatment.
• Distractions in the operating room: Noise, interruptions or lack of focus during a procedure can lead to missed steps, wrong decisions and preventable errors.
• Equipment failure: A device such as an electrocautery tool, monitor or surgical robot malfunctions and contributes to patient harm.
• Failure to monitor vital signs: A surgical team misses or ignores warning signs like low oxygen or abnormal blood pressure and allows a preventable crisis to develop.
• Inadequate training: A hospital or provider allowing staff to perform tasks without the skill or supervision needed for safe care can have serious consequences.
• Objects left inside the body: A surgical team leaves sponges, clamps or other tools inside a patient, which can cause infection, pain and additional surgery.
• Organ perforation: A surgeon punctures an organ such as the bowel or bladder during surgery, which can cause infection, bleeding and emergency repair.
• Wrong-site surgery: A surgeon performs a procedure on the wrong body part, the wrong side of the body or the wrong patient. In some cases, the surgeon may even remove the incorrect organ or limb, causing permanent and life-altering loss.

At Dudley & Lake, we review operative reports, anesthesia records, nursing notes, imaging and follow-up care so we can identify what went wrong and who caused it. We look at the full chain of events, including how the team prepared for surgery, how it managed risk in the operating room and how it monitored you after the procedure.

Wrong-Site Surgery: A “Never Event” That Causes Lasting Harm

Wrong-site surgery stands out as one of the most serious and preventable surgical mistakes a patient can face. These errors occur when a surgeon operates on the wrong body part, the wrong side of the body or the wrong patient.

Wrong site surgeries often trace back to failures in basic safety steps such as surgical “time out” procedures, chart review and clear team communication. Wrong-site surgery can also happen when the team uses incorrect markings, relies on incomplete records or rushes under schedule pressure.

The damage from wrong-site surgery can go far beyond the initial mistake. A patient may lose healthy tissue or function, face additional surgeries and experience permanent pain or disability. In many cases, the patient also still needs the original surgery on the correct site, which adds more risk, more recovery time and more financial strain. Our wrong-site surgery attorneys build these cases around the full impact on health, work and quality of life.
