The surgical removal of a section or segment of an organ or other structure.



an operation that involves the partial excision of a diseased organ. Amputation is the removal of the peripheral part of an organ, while extirpation is the complete removal of an organ. In surgical practice gastric resections are most frequently performed; pyloric stenoses and stomach cancers or gastric ulcers that are complicated by hemorrhaging often require gastric resections. Resections of the small or large intestine are performed in cases of traumatic ruptures, obstructions, or tumors. An anastomosis is created between the stump of the stomach and the duodenum or jejunum or between the remaining sections of the intestine after gastric or intestinal resections. Resections are also performed on the thyroid gland, lungs, and joints.
