Nesbit’s Operation: From 1 Different Sources
an operation devised to surgically straighten a congenitally curved penis but now more frequently employed to correct the penile curvature caused by *Peyronie’s disease. The procedure can often result in penile shortening. [R. M. Nesbit (20th century), US surgeon]
A technique by which narrowing or blockage of an artery (see ARTERIES), vein (see VEINS) or a section of the gastrointestinal tract is bypassed using surgery. Arterial blockages – usually caused by ATHEROSCLEROSIS – in the carotid, coronary or iliofemoral arteries are bypassed utilising sections of artery or vein taken from elsewhere in the patient. Tumour growths in the intestines are sometimes too large to remove and can be bypassed by linking up those parts of the intestines on each side of the growth.... bypass operation
A surgical procedure using instruments – or sometimes just the hands; for example, when manipulating a joint or setting a simple fracture. Operations range from simple removal of a small skin lesion under local anaesthetic to a major event such as transplanting a heart which takes several hours and involves many doctors, nurses and technical sta?. Increasingly, operations are done on an outpatient or day-bed basis, thus enabling many more patients to be treated than was the case 25 years ago, and permitting them to resume a normal life – often within 24 hours.

Procedures to bypass the blockage or narrowing of an artery or vein or any part of the digestive system. Arteries can become blocked or narrowed in atherosclerosis. Obstructions can be bypassed using sections of healthy artery or vein from elsewhere in the body or using synthetic tubing. Veins are bypassed most often in patients with diseases of the liver that cause portal hypertension and bleeding oesophageal varices. This kind of bypass is called a shunt. Intestinal bypasses are employed most commonly in patients with cancer in which tumour growth is too extensive to be removed. An obstructed bile duct can be bypassed by constructing a new opening into the digestive tract. (See also coronary artery bypass.)... bypass operations

a major operation performed to remove a malignant tumour from the head and neck. Extensive dissection, often involving the face, is followed by reconstruction to restore function and cosmetic acceptability.... commando operation
a method of reconstruction after surgical removal of the distal colon and proximal rectum, in which the rectal stump is closed off and the divided end of the colon is brought out as a *colostomy. The technique allows for a second operation to join up the bowel ends and obviates the need for a stoma. It is often used temporarily where primary anastomosis is unsafe (e.g. in cases of perforated *diverticular disease) or permanently as a palliative procedure (e.g. for unresectable colonic cancer).
