A surgical error is a preventable mistake or failure during a surgical procedure that causes harm, worsens a patient’s condition, or requires additional treatment. The term may involve the wrong procedure, an avoidable injury, retained surgical material, or a failure to respond properly to a known complication.

How Surgical Error Works

Surgical error describes a mistake, omission, or failure during an operation or related surgical care. The conduct may occur before the procedure, during the operation, or during immediate follow-up. Examples include operating on the wrong site, leaving an object in the body, or causing avoidable damage to nearby tissue.

Reviewers examine the medical record, consent documents, surgical notes, medication records, and follow-up findings. They compare the care provided with the care a qualified professional would reasonably provide in similar circumstances. A complication can happen even when the medical team follows appropriate practices, so an injury alone does not establish malpractice. Medical records and opinions from qualified medical professionals can help connect the conduct to the harm.

From the Atlanta Auto Law team
When we review a possible surgical error, we organize the medical records around the procedure, the injury, and the follow-up care. We look for evidence that identifies the act or omission, connects it to the harm, and supports the applicable medical malpractice claim.
Surgical Error in Practice: A Real-World Example
A patient undergoes surgery for a condition affecting one side of the body, but the procedure occurs on the wrong side. The patient then needs additional treatment, and the records become central to evaluating the resulting medical malpractice claim.
