OPINION OF THE COURT
Plaintiff Marguerite James commenced this medical malpractice action against defendants Dr. David Wormuth and his practice, CNY Thoracic Surgery, EC., after he failed to remove a localization guide wire during a biopsy of an area on plaintiffs lung. On this aрpeal from the Appellate Division order affirming the dismissal of her amended complaint, we affirm.
In October 2004, a guide wire inserted into the plaintiff to assist with a biopsy of an area in her lung dislodged. Defendant Dr. Wormuth proceeded with the biopsy, but was unable to locate the dislodged wire. After an unsuccessful 20-minute manual search for the wire, defendant determined that it was better for the plaintiff to leave the wire and end the surgical procedure, rather than to extend the amount of time she was in surgery for him to continuе searching for the wire. Defendant informed plaintiff after the surgery that he could not find the wire, and that he had determined that it was better to leave it rather than continue the search procedure.
Plaintiff subsequently returned to defendant complaining of pain she attributed to the lodged wire, and which she said was so significant that it disrupted her ability to work. Approximately two months after the first procedure, defendant performed a second operation. In that procedure, he successfully
Plaintiff then commenced this medical malpractice action.
At the close of plaintiffs case, defendants moved to dismiss for failure to establish a prima facie case of medical malpractice. Defendants argued that plaintiff failed to show a deviation from accepted standards of medical practice, and also that such deviation was the proximate cause of the plaintiffs injury. Defendants pointed specifically to plaintiff’s failure to present any expert proof on the standard of practice. Anticipating plaintiffs response, defendants argued that res ipsa loquitur wаs inapplicable because there was no evidence of any error by Dr. Wormuth that caused the wire to become dislodged.
Plaintiff objected to the motion and argued that expert testimony was unnecessary because Dr. Wormuth admitted that he intentionally left the wire inside the plaintiff. Therefore, a jury could infer negligence given that there was no medical reason to leave the wire lodged in plaintiff, and defendant could have obtained a C-arm to locate and remove it. Plaintiff asserted that rеs ipsa loquitur necessarily applied because the wire was a foreign object that could only have been left in the plaintiff as a result of the doctor’s negligence.
During argument on the motion, and in response to the court’s specific inquiry as to the plaintiffs theory of the case, plaintiffs counsel confirmed that the case focused on defendant’s failure to remove the wire.
*545 “[The court]: . . . Your theory here is that he committed negligence and malpractice by failing to retrieve it back on Oсtober the 28th —
“[Counsel]: Right.
“[The court]: — during the first surgery?
“[Counsel]: As it’s gone in, your Honor, that is the case. If I had an expert, it would have been a different one, but that’s what the case is right now.”
The court subsequently granted a directed verdict in defendants’ favor, pursuant to CPLR 4401.
The Appellate Division affirmed in a 3-2 decision (
On appeal before this Court, plaintiff continues to press her arguments that expert testimony was unnecessary, and that res ipsa loquitur applies to this case because the fact that the wire was lеft in the plaintiff in and of itself establishes defendants’ liability. Plaintiff further argues that the wire should be treated as a foreign object left inside the plaintiff, and therefore negligence may be inferred.
Ordinarily, a plaintiff asserting a medical malpractice claim must demonstrate that the doctor deviated from acceptable medical practice, and that such deviation was a proximate cause of the plaintiffs injury (see Rivera v Kleinman,
“[1.] the event must be of a kind that ordinarily does not occur in the absence of someone’s negligence;
“[2.] it must be caused by an agency or instrumentality within the exclusive control of the defendant; and
“[3.] it must not have been due to any voluntary action or contribution on the part of the plaintiff” (Kambat,89 NY2d at 494 ; see Prosser and Keeton, Torts § 39 at 244 [5th ed]).
Further, in the context of a medical malpractice case based upon a foreign object, “[r]es ipsa loquitur is applicable whеre . . . [the object] is unintentionally left in a patient following an operative procedure” (LaPietra v Clinical & Interventional Cardiology Assoc.,
According to the record, plaintiff constructed her case on a theory based on the doctor’s intentional choice to leave the wire inside the plaintiff, and her counsel specifically acknowledged this to the trial court. Moreover, her counsel conceded at trial that he had not submitted opinion testimony about the standard of medical care,
Dr. Wormuth’s testimony reveals that he claimed to have exercised his professional judgment during the biopsy procedure. The doctor testified that he decided to leave the wire inside the plaintiffs chest because, in his judgment, he believed it to be riskier to continue, noting that this would extend the period under which the plaintiff was anaesthetized, and require a larger incision in order to find and remove the wire. He further testified that in his experience patients cоuld tolerate wires, that wires are under some circumstances left inside a patient, and he believed he could remove the wire in this case, if necessary, at a later time.
It is clear from the record that the doctor explained his decision to leave the wire in terms of his medical assessment of what was best for the patient under the circumstances. Defendant’s testimony that it was his professional judgment to leave the wire could not be assessed by the jury based on the “common knowledge of lay persоns” (Lourdes Hosp.,
To the extent counsel argued that res ipsa loquitur applies because the wire could only have dislodged due to the doctor’s negligence, plaintiff failed to establish the elements of res ipsa, specifically that Dr. Wormuth had exclusive control (see Dermatossian v New York City Tr. Auth.,
Plaintiff’s argument that the wire should be treated as a foreign object in support of her res ipsa claim is unpersuasive because her theory of the case was the doctor negligently chose to leave the wire. Thus, this case is distinguishable from those involving objects left unintentionally, where, as plaintiff argues, no decision to leave the object has been made which must be measured against a standard of care. Plaintiffs other contention that the defendant cоmmitted gross negligence is similarly without merit.
Here, defendant exercised his professional judgment when he chose to leave the object in the plaintiff, and plaintiff did not present any expert evidence that by so doing, the defendant departed from accepted standards of medical care. Plaintiff failed to demonstrate a prima facie case of medical malpractice based upon res ipsa loquitur, or traditional negligence principles. “As advantageous as the res ipsa lоquitur inference is for a plaintiff unable to adduce direct evidence of negligence, application of the [evidentiary] doctrine does not relieve a plaintiff of the burden of proof’ (Lourdes Hosp.,
Accordingly, the Appellate Division order should be affirmed, with costs.
Chief Judge Lippman and Judges Graffeo, Read, Smith, Pigott and Abdus-Salaam concur.
Order affirmed, with costs.
Notes
. Supreme Court granted defendant’s summary judgment motion dismissing plaintiffs original complaint. Plaintiff successfully appealed, and the Appellate Division reinstated the complaint (see
. Counsel admitted before the trial court that he “did not introduce an opinion, that this was a breach of accepted standard of medical care. That’s about all we really don’t have.”
. Plaintiffs contention that defendant was negligent because he left the wire when he could have used the C-arm to locate it during the first surgery further establishes that the plaintiffs case turned on the propriety of the doctor’s choice to leave the wire in the plaintiff and that expert opinion was necessary.
