Questions tagged [surgery]

To employ operations in the treatment of disease or injury, or for experimental purposes. Surgery can involve cutting, abrading, suturing, or otherwise physically changing body tissues and organs.

Surgery is the subspecialty of medicine, performed by surgeons, that deals with the operative management of pathologic conditions in humans and other animals, or to operations performed for experimental purposes. The Surgery tag should be used on questions that discuss diseases or other conditions that can be treated by a surgeon, or when dealing with animal studies involving invasive procedures. Surgery can be used as an intervention to improve bodily function, bodily appearance, or repair damaged tissues. Experimentally, it can alternatively be deployed to deliberately invoke defects in otherwise healthy animals, or to implant devices or materials in animal models.
