#resection

• Adenectomy — A surgical intervention consisting of the complete or partial extirpation or resection of a gland or a lymph node affected by a pathological process. This structural surgical procedure is frequently used to remove glandular tumors, relieve obstructive complications, or eliminate severe infectious foci from the lymphatic system.
• Alveolectomy — A dental surgical procedure consisting of the partial or total resection of the bony margins of a tooth socket or a portion of the jaw's alveolar ridge. This structural procedure is usually performed after complex extractions or for pre-prosthetic purposes, to smooth the bone and facilitate the subsequent placement of a dental prosthesis.
• Ampulloma — A tumor formation, either benign or malignant, structurally developed at the level of the ampulla of Vater (the confluence area of the common bile duct and the main pancreatic duct into the duodenum). This neoplasm frequently causes early obstructive jaundice by blocking the biliary flow and requires advanced imaging investigations and complex surgical intervention for resection.
• Amputation — The act of amputating and its result; a surgical operation through which a limb, an extremity of the body, or an organ segment is partially or totally removed due to severe trauma, severe infections (gangrene), or malignant tumors. Figuratively or economically, it represents the drastic reduction, curtailment, or forced suppression of a part of a budget, text, or set of privileges.
• Amputation — A major surgical act consisting of the total or partial removal of a limb or body extremity through a bone plane, performed to eliminate necrotic, tumorous, or irreparably traumatized tissue. This technical procedure is vital for halting fulminant infections, such as gangrene, and requires rigorous vascular techniques to allow optimal healing of the residual stump.
• Angiectomy — A specialized surgical intervention consisting of the resection, extirpation, or total or partial removal of a blood vessel (artery or vein) or a lymphatic vessel affected by a severe pathology. This operative structural procedure is utilized in cases of aneurysms, complex vascular malformations, irreversible massive thromboses, or vascular tumors, aiming to restore circulatory safety or eliminate diseased tissue.
• Angioneurectomy — A specialized surgical intervention consisting of the extirpation, resection, or total or partial removal of a structural assembly formed by a blood vessel and its afferent vegetative nerve fibers. This complex operative procedure is utilized in niche cases to interrupt chronic vascular spasm or treat painful syndromes of rebellious peripheral neuro-vascular etiology unresponsive to other forms of therapy.
• Antropylorectomy — A major surgical intervention consisting of the partial or total excision of the lower stomach region, including both the gastric antrum and the pylorus (the muscular sphincter leading to the duodenum). This specialized surgical procedure is urgently performed in severe cases of infiltrative gastric neoplasm, refractory gastric ulcers complicated by tight pyloric stenosis, or massive perforations.
• Aortectomy — A highly complex surgical procedure consisting of the partial or total resection of the aorta, usually performed to excise a segment severely damaged by a massive aneurysm, acute dissection, or a vascular tumor. The excised segment is structurally replaced with a synthetic or biological graft to restore systemic blood flow continuity.
• Apicoectomy — A dental surgical procedure (also known as apicoectomy or root-end resection) consisting of the surgical removal of the apex (tip) of a tooth root, along with the surrounding necrotic or infected bone tissue. This surgical endodontic treatment is applied when classic root canal treatments fail, aiming to save the tooth from extraction.
• Apicoectomy — A dental surgical procedure consisting of the surgical removal of the apex (tip) of a tooth root, along with the surrounding infected or necrotic bone tissue. Widely known also as root-end resection or apicoectomy, it is applied when classic endodontic root canal treatment fails.
• Apicotomy — A surgical intervention consisting of the sectioning or incision of an apex (tip); in dentistry, it represents the surgical cutting of the root tip of a tooth to eliminate a persistent periapical infection, often used as a partial synonym for root-end resection. In an otorhinolaryngological context, it describes the surgical incision or drainage of the petrous apex of the temporal bone in severe cases of petrositis.
• Arteriectomy — A surgical operation consisting of the partial or total resection of a diseased or obstructed artery, usually followed by the restoration of blood flow through a vascular graft (anastomosis) or a synthetic prosthesis. It is a complex procedure utilized in treating severe aneurysms or acute arterial occlusions.
• Arthrectomy — A surgical operation consisting of the total or partial excision of a diseased or structurally compromised joint; an articular resection. It is an invasive procedure utilized in severe cases of bone destruction, incurable joint infections, or tumors, often representing the preliminary stage of an arthrodesis or arthroplasty.
