PLAINTIFF ALLEGED DEFENDANT NEGLIGENTLY PERFORMED A ROBOTIC ASSISTED LAPAROSCOPIC ADRENALECTOMY; PLAINTIFF’S EXPERT, A GENERAL SURGEON WHO WAS EXPERIENCED IN LAPAROSCOPIC SURGERY, BUT NOT ROBOTIC SURGERY, SHOULD NOT HAVE BEEN PRECLUDED FROM TESTIFYING; THE LACK OF EXPERIENCE WITH ROBOTIC SURGERY WENT TO THE WEIGHT OF THE TESTIMONY, NOT ITS ADMISSIBILITY (SECOND DEPT).

The Second Department, reversing Supreme Court’s dismissal of the medical malpractice complaint, determined the testimony of the plaintiff’s expert, a general surgeon, should not have been precluded on the ground he was not qualified to testify about robotic surgery. The complaint alleged the defendant negligently performed a robotic assisted laparoscopic adrenalectomy:

“A medical expert need not be a specialist in a particular field in order to testify regarding accepted practices in that field, but the witness should be possessed of the requisite skill, training, education, knowledge, or experience from which it can be assumed that the opinion rendered is reliable” … . Here, the plaintiff’s expert, a board certified general surgeon, testified that he had knowledge of adrenalectomies and the splenic vein based on his education and training, had performed surgeries involving the adrenal gland, and had extensive experience performing laparoscopic surgeries, and he opined that the principles of good surgical practice with respect to the isolation, preservation, and protection of adjacent organs were the same regardless of whether a surgery was performed openly, laparoscopically, or robotically. This testimony was sufficient to demonstrate that the plaintiff’s expert was qualified to render an opinion regarding the standard of care for a robotic assisted laparoscopic adrenalectomy … . The expert’s lack of experience in performing robotic assisted laparoscopic adrenalectomies goes to the weight of his testimony, not its admissibility … . Lynch v Wang, 2026 NY Slip Op 00887, Second Dept 2-28-26

Practice Point: A medical expert need not be a specialist in a particular field to testify about accepted practices in that field. Here the plaintiff alleged defendant negligently performed robotic surgery. Plaintiff’s expert, a general surgeon who was not experienced in robotic surgery, should not have been precluded from testifying.
