San Diego Surgical Error Lawyer

Surgery comes with accepted risks, and patients sign consent forms understanding that. What patients do not sign up for is a surgeon operating on the wrong knee, a sponge left inside the abdomen, or a nicked bowel that goes unrecognized for three days. Those outcomes are preventable, and they reshape lives permanently.

When a surgeon, anesthesiologist, or operating room team causes harm through negligence, patients and families are the ones left with the medical bills, the corrective procedures, and the long road of recovery. Some injuries heal. Others do not.

Thorsnes Bartolotta McGuire has represented patients harmed by surgical negligence in San Diego for 48 years and has recovered more than $2 billion in verdicts and settlements. Founding partner Vincent J. Bartolotta Jr. was named Nice Guy of the Year in 2025, a recognition that reflects how every client is treated at our firm.

Why Do Surgical Errors Happen?

Most surgical errors trace back to a chain of preventable breakdowns in preparation, communication, and oversight. Knowing why these mistakes happen can help you recognize when something went wrong in your own care.

Common causes our firm sees include:

• Poor communication during shift changes, team handoffs, and transfers between departments
• Fatigue and understaffing that push providers past the point where they can safely focus on a procedure
• Skipped safety protocols including verification checklists, time-outs, and instrument counts
• Inadequate preoperative planning such as failing to review imaging, lab work, or patient history before cutting
• Anesthesia providers monitoring more than one patient at a time and missing critical warning signs
• Surgeons operating outside their training or attempting procedures they lack the experience to perform safely
• Hospital system failures including poor credentialing, lax infection control, and inadequate staffing ratios

Providers and hospitals have safeguards designed to catch these problems before they reach the patient. When those safeguards are ignored, the patient is the one who pays for it.

A 2024 study published in the BMJ, which analyzed more than 75,000 malpractice cases, reinforced that surgical mistakes remain the leading cause of medical lawsuits, accounting for over 25% of all claims.

Which Surgical Errors Are Most Common in San Diego?

Our surgical malpractice attorneys in San Diego have handled claims across virtually every surgical specialty, from orthopedic and cardiac procedures to elective cosmetic work. The types of mistakes we see most often include:

• Wrong-site, wrong-procedure, or wrong-patient surgery. These “never events” still occur. Patients may undergo surgery on the wrong body part or receive an entirely different procedure than planned—errors that should never happen with proper safeguards in place.
• Retained surgical objects. Sponges, clamps, or needles left inside the body can cause infection, organ damage, and the need for additional surgery. These cases often point to breakdowns in basic safety protocols like instrument counts.
• Nerve, vessel, or organ damage. Surgical mistakes can sever nerves, puncture organs, or cause internal bleeding. When these injuries are not recognized and treated promptly, the consequences can escalate quickly.
• Anesthesia errors. Improper dosing, failure to review medical history, or inadequate monitoring can lead to brain injury, anesthesia awareness, cardiac arrest, or death.
• Postoperative infections and sepsis. Failures in sterilization or infection control can expose patients to serious infections that may become life-threatening within hours.
• Failure to recognize complications. Even when complications arise, the surgical team must act quickly. Discharging a patient too soon or overlooking signs of internal bleeding or infection can worsen the harm.
• Cosmetic surgery errors. Elective procedures carry the same legal standard of care as any surgery. Errors often involve unqualified providers, unsafe facilities, or poor follow-up care, leading to disfigurement, chronic pain, or costly revision procedures. Cosmetic surgery centers and med spas are held to the same standards as hospitals.

Who Can a San Diego Surgical Errors Lawyer Hold Accountable?

One of the most important jobs for a San Diego surgical errors attorney is identifying everyone who played a part in the injury. It isn't always just the surgeon at the table. Depending on what went wrong, responsible parties might include:

• Individual doctors or specialists
• Nurses and nursing assistants
• Hospitals or medical groups
• Pharmacists
• Laboratory technicians
• Physical therapists
• Dentists
• Physician's assistants
• Optometrists
• Chiropractors

Hospitals can also be liable for their employees' mistakes and for their own negligence, such as failing to properly vet a surgeon before giving them "privileges" to operate there. A surgeon with falsified credentials, a disciplinary record, or inadequate training should never be in the operating room, and the hospital that cleared them shares responsibility.

How Our San Diego Surgical Malpractice Lawyers Prove Your Case

Telling a provider's insurance carrier that a surgery went badly is not enough on its own. California requires proof of four specific legal elements in every surgical malpractice claim, each backed by documentation and expert medical analysis:

1. Duty. A provider-patient relationship existed, meaning the surgeon, anesthesiologist, or other member of the surgical team owed you a professional obligation to provide competent care.
2. Breach. The provider departed from what a reasonably skilled practitioner in the same specialty would have done under similar circumstances. Operating on the wrong site, failing to perform an instrument count, or ignoring a clear indication of internal bleeding are all examples.
3. Causation. The breach is what caused your injury, not an underlying condition or an unrelated event. A direct, documented link between the provider's conduct and the harm is essential.
4. Damages. The injury resulted in measurable losses, whether physical disability, psychological trauma, mounting medical bills, lost income, or reduced quality of life.

California law requires a qualified medical expert to support a malpractice claim. A surgeon, anesthesiologist, or other specialist reviews your records and provides sworn testimony identifying how the standard of care was breached and how that failure caused your injury. Without that opinion, the case cannot proceed.

The expert’s qualifications are critical. In a wrong-site surgery case, the witness should practice in the same subspecialty as the defendant. In an anesthesia case, a board-certified anesthesiologist must be able to pinpoint what the monitoring data showed and when intervention was required.

For 48 years, Thorsnes Bartolotta McGuire has built relationships with surgeons, anesthesiologists, nurses, and other professionals willing to testify candidly about surgical errors. Combined with the resources to retain leading experts through trial, that network has helped the firm recover more than $2 billion for clients across Southern California.

A Martindale-Nolo survey found that represented claimants recovered an average of $77,600—about four times more than the $17,600 average for those who handled claims alone. More than 90% of represented claimants received compensation, compared to roughly half of those without legal representation.

How Can I Start a Surgical Error Lawsuit in San Diego?

You do not need to have everything figured out before you reach out to a lawyer. Most people who call our firm are still piecing together what happened and whether it was preventable. Once you make that call, the claim generally moves through these stages:

• Medical records review. Your attorney collects and reviews every relevant document, including operative reports, anesthesia logs, imaging, pathology reports, and nursing notes.
• Expert evaluation. A qualified medical expert in the appropriate specialty reviews the records to determine whether the standard of care was violated.
• Pre-suit notice. California Code of Civil Procedure Section 364 requires a 90-day notice of intent to sue be served on each defendant before the lawsuit is filed.
• Filing and discovery. Once the complaint is filed, both sides exchange documents, take depositions, and retain additional experts.
• Settlement or trial. Many surgical malpractice cases resolve through settlement during or after discovery, but every case should be prepared as if it will go to trial.

California’s Medical Injury Compensation Reform Act (MICRA) caps noneconomic damages in malpractice cases. As of 2026, the limit is $470,000 for non–wrongful death claims and $650,000 for wrongful death, with annual increases through 2033. Economic damages, such as medical costs, lost income, and future care, remain uncapped.

"There's really no secret about what I do. I really do care for my clients. Each case gets the same kind of attention my family would get."
