Thoracic surgery experts address operations on the lungs, esophagus, mediastinum, pleura, chest wall, diaphragm, and airway. The distinction from cardiothoracic surgery matters in expert selection and is built into the certification itself. The American Board of Thoracic Surgery offers three operative pathways -- Cardiothoracic, General Thoracic, and Cardiac -- and a resident must satisfy the index case requirements entirely from one declared pathway, though only one certificate is issued whatever pathway is chosen 1. Volume requirements run alongside: an annual average of 125 major operations, totaling 250 cases in two-year programs and 375 in three-year and six-year programs 1. The practical consequence is that two surgeons can hold identical ABTS certificates while one has spent a career doing coronary bypass and valves and the other doing lobectomies and esophagectomies. When the operation at issue is a lung resection, the general thoracic surgeon is the witness; board certification alone does not settle the question.
Oncologic decision-making is the largest source of engagements, and the profession has moved quickly enough that the applicable standard depends heavily on the year of the operation. Two randomized trials established sublobar resection as noninferior to lobectomy in node-negative non-small cell lung cancer of 2 cm or less, and use of sublobar resection rose sharply as a result; the Society of Thoracic Surgeons issued a 2026 expert consensus document, developed by modified Delphi to greater than 75 percent agreement across 21 statements, to define the operation and guide its appropriate use 2. Cases now turn on whether a segmentectomy or wedge was appropriate for the tumor and the nodal status, whether adequate margins and lymph node sampling were obtained, and whether the intraoperative findings should have converted the plan to a lobectomy. Related guidance addresses pulmonary resection as local consolidative therapy in oligometastatic non-small cell lung cancer, where the STS panel identified seven areas of controversy and set best practices for patient selection 3.
Esophageal surgery generates the highest-severity claims in the specialty. Anastomotic leak, conduit necrosis, recurrent laryngeal nerve injury, chylothorax, and aspiration after esophagectomy are recognized complications, so the litigated questions are typically whether the patient was properly staged and selected, whether neoadjuvant therapy should have preceded the operation, whether the leak was recognized and managed promptly, and whether the operation should have been performed at a center with the relevant volume. The STS, the American Society for Radiation Oncology, and the American Society of Clinical Oncology jointly issued updated clinical practice guidelines on multimodality therapy for locally advanced cancer of the esophagus and gastroesophageal junction, addressing eight key clinical questions in the care of these patients 4.
Delayed diagnosis is the other major front, and it usually reaches the thoracic surgeon through imaging rather than through an operation. Incidental pulmonary nodules identified on chest imaging and never followed up, screening studies that were performed and not acted on, and abnormal findings communicated to no one are the recurring fact patterns. The U.S. Preventive Services Task Force gives a B recommendation to annual low-dose computed tomography screening for adults aged 50 to 80 years with a 20 pack-year smoking history who currently smoke or quit within the past 15 years, and expressly conditions continued screening on the patient's ability and willingness to undergo curative lung surgery 5. That recommendation supplies a benchmark for who should have been screened and for what the follow-up obligation was once a nodule appeared.
Outcomes in this field are measured, which changes discovery. The STS General Thoracic Surgery Database is the largest and most robust clinical thoracic surgical database in North America, holding nearly 800,000 general thoracic surgery procedure records with more than 900 participating surgeons 6. STS publicly reports participant results for resection for primary lung cancer and for esophagectomy for esophageal cancer, benchmarked against the Agency for Healthcare Research and Quality's National Inpatient Sample 7. Where the defendant institution participates, risk-adjusted expected outcomes usually exist for the specific operation, which lets an expert separate a recognized complication within the expected range from a result that requires explanation -- and makes the institution's own participation and reporting practice a subject of examination in its own right.
The remaining case types are technical and procedural. Common allegations include injury to the recurrent laryngeal or phrenic nerve; prolonged air leak and bronchopleural fistula after resection; inadequate lymph node dissection affecting staging and adjuvant therapy; malpositioned, mismanaged, or prematurely removed chest tubes; tension pneumothorax and iatrogenic pneumothorax after line placement or biopsy; empyema and delayed decortication; injury during video-assisted thoracoscopic and robotic approaches, including conversion decisions; tracheal and airway surgery complications and post-intubation stenosis; mediastinal mass and thymectomy injuries; and retained surgical items. Thoracic surgeons are also retained in product liability matters involving surgical staplers, energy devices, chest drainage systems, and endobronchial valves, where the question is whether the device failed or was misapplied.
The American Board of Thoracic Surgery issues a single certificate but requires residents to satisfy their index case requirements entirely from one declared pathway -- Cardiothoracic, General Thoracic, or Cardiac -- so two surgeons can hold the same certificate with materially different experience in the operation being litigated.

FAQ
In certification they share a board; in practice they often do not share an operation. The American Board of Thoracic Surgery issues a single certificate, but residents must satisfy their index case requirements entirely from one declared pathway — Cardiothoracic, General Thoracic, or Cardiac. A general thoracic surgeon operates on the lungs, esophagus, mediastinum, pleura, chest wall, and airway; a cardiac surgeon operates on the heart and great vessels. For a lobectomy, an esophagectomy, or a tracheal resection, the general thoracic surgeon is the appropriate expert, and the pathway a candidate declared is a fair and often decisive subject of voir dire.
Board certification by the American Board of Thoracic Surgery, current or recent operative experience in the specific procedure at issue, and general thoracic rather than cardiac operative experience where the case involves the lungs, esophagus, or airway. The surgical approach matters as well — an expert who has never performed a robotic lobectomy is a weak witness on robotic conversion decisions. Practice at an institution participating in the STS General Thoracic Surgery Database, and familiarity with the STS guidelines in force at the time of the operation, both strengthen the opinion.
Lung resection complications, disputes over lobectomy versus sublobar resection and the adequacy of margins and lymph node sampling, esophagectomy complications including anastomotic leak, delayed diagnosis of lung cancer from missed pulmonary nodules or unacted-upon screening studies, chest tube and pneumothorax management, empyema and delayed decortication, video-assisted thoracoscopic and robotic surgery injuries, tracheal and mediastinal procedures, and product liability matters involving staplers, energy devices, and chest drainage systems.
It usually supplies the benchmark and a discovery target. The STS General Thoracic Surgery Database is the largest clinical thoracic surgical registry in North America, with nearly 800,000 procedure records and more than 900 participating surgeons, and STS publicly reports participant results for resection for primary lung cancer and esophagectomy for esophageal cancer, benchmarked against the AHRQ National Inpatient Sample. Where the defendant institution participates, an expert can compare the observed result against risk-adjusted expectations for that operation, which separates a recognized complication from an outcome that calls for explanation. The institution's participation status and its own reported outcomes are frequently sought.
Not on its own, and the answer depends on the date and the tumor. Two randomized trials found sublobar resection noninferior to lobectomy for node-negative non-small cell lung cancer of 2 cm or less, and its use rose accordingly; the Society of Thoracic Surgeons issued a 2026 expert consensus document reaching greater than 75 percent agreement on 21 statements to define the operation and guide its appropriate use. The analysis therefore asks what the evidence and guidance supported when the operation was performed, whether the tumor size and nodal status fit the trial populations, and whether adequate margins and lymph node sampling were achieved.
Usually more than one. The radiologist's reporting and communication of the finding, the ordering or primary clinician's follow-up, and the thoracic surgeon's opinion on resectability, staging, and what outcome timely surgery would have produced are separate opinions that different experts must give. The thoracic surgeon's role is generally causation and damages — whether the cancer was resectable at the earlier stage and what the prognosis would have been — while the screening obligation itself is framed by the U.S. Preventive Services Task Force recommendation for annual low-dose CT in adults aged 50 to 80 with a 20 pack-year history who smoke or quit within the past 15 years.
In general, medical expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are clinical experience, forensic experience, academic qualifications such as Fellowships, clinical settings, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
