Surgery is a medical specialty that uses manual and/or instrumental techniques to physically reach into a subject's body in order to investigate or treat pathological conditions such as a disease or injury, to alter bodily functions, to improve appearance, or to remove/replace unwanted tissues or foreign bodies. The subject receiving the surgery is typically a person, but can also be a non-human animal.
Laparoscopy is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.
Tonsillectomy is a surgical procedure in which both palatine tonsils are fully removed from the back of the throat. The procedure is mainly performed for recurrent tonsillitis, throat infections and obstructive sleep apnea (OSA). For those with frequent throat infections, surgery results in 0.6 fewer sore throats in the following year, but there is no evidence of long term benefits. In children with OSA it results in improved quality of life.
Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis.
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.
Gender-affirming surgery for female-to-male transgender people includes a variety of surgical procedures that alter anatomical traits to provide physical traits more comfortable to the trans man's male identity and functioning.
A Nissen fundoplication, or laparoscopic Nissen fundoplication when performed via laparoscopic surgery, is a surgical procedure to treat gastroesophageal reflux disease (GERD) and hiatal hernia. In GERD, it is usually performed when medical therapy has failed; but, with a Type II (paraesophageal) hiatus hernia, it is the first-line procedure. The Nissen fundoplication is total (360°), but partial fundoplications known as Thal, Belsey, Dor, Lind, and Toupet fundoplications are alternative procedures with somewhat different indications and outcomes.
Dupuytren's contracture is a condition in which one or more fingers become permanently bent in a flexed position. It is named after Guillaume Dupuytren, who first described the underlying mechanism of action, followed by the first successful operation in 1831 and publication of the results in The Lancet in 1834. It usually begins as small, hard nodules just under the skin of the palm, then worsens over time until the fingers can no longer be fully straightened. While typically not painful, some aching or itching may be present. The ring finger followed by the little and middle fingers are most commonly affected. It can affect one or both hands. The condition can interfere with activities such as preparing food, writing, putting the hand in a tight pocket, putting on gloves, or shaking hands.
Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch and then the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP). Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
Cataract surgery, which is also called lens replacement surgery, is the removal of the natural lens of the human eye that has developed a cataract, an opaque or cloudy area. The eye's natural lens is usually replaced with an artificial intraocular lens (IOL).
Chin augmentation using surgical implants can alter the underlying structure of the face, providing better balance to the facial features. The specific medical terms mentoplasty and genioplasty are used to refer to the reduction and addition of material to a patient's chin. This can take the form of chin height reduction or chin rounding by osteotomy, or chin augmentation using implants. Improving the facial balance is commonly performed by enhancing the chin using an implant inserted through the mouth. The goal is to provide a suitable projection of the chin as well as the correct height of the chin which is in balance with the other facial features.
Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.
Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, along the greater curvature, which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana. Weight loss is affected not only through the reduction of the organ's size, but by the removal of the portion of it that produces ghrelin, the hormone that stimulates appetite. Patients can lose 50-70 percent of excess weight over the course of the two years that follow the surgery. The procedure is irreversible, though in some uncommon cases, patients can regain the lost weight, via resumption of deleterious habits, or dilation of the stomach over time, which can require gastric sleeve revision surgery to either repair the sleeve or convert it to another type of weight loss method that may produce better results, such as a gastric bypass or duodenal switch.
A surgical nurse, also referred to as a theatre nurse or scrub nurse, specializes in perioperative care, providing care to patients before, during and after surgery. To become a theatre nurse, Registered Nurses or Enrolled Nurses must complete extra training. Theatre nurses can focus on different speciality areas, depending on which they are interested in.
A subspecialty (US English) or subspeciality is a narrow field of professional knowledge/skills within a specialty of trade, and is most commonly used to describe the increasingly more diverse medical specialties. A subspecialist is a specialist of a subspecialty.
Zygoma reduction, also known as cheekbone reduction surgery, is a surgery used to reduce the facial width by excising part of the zygomatic bone and arch. Wide cheekbones are a characteristic facial trait of Asians, whose skull shapes tend to be more brachycephalic in comparison with Caucasian counterparts, whose skull shapes tend to be more dolichocephalic .This surgery is popular among Asians due to their inherent wide cheekbones. Due to the advanced surgical skills of Korean surgeons who perform facial contouring surgeries, the number of Asian people undergoing this surgery is increasing.
Reproductive surgery is surgery in the field of reproductive medicine. It can be used for contraception, e.g. in vasectomy, wherein the vasa deferentia of a male are severed, but is also used plentifully in assisted reproductive technology. Reproductive surgery is generally divided into three categories: surgery for infertility, in vitro fertilization, and fertility preservation.
Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region.
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling. Postoperative wounds are different from other wounds in that they are anticipated and treatment is usually standardized depending on the type of surgery performed. Since the wounds are 'predicted' actions can be taken beforehand and after surgery that can reduce complications and promote healing.
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
