• Adenoid — Resembling a gland or glandular tissue in structure or function; in anatomy, the plural noun (adenoids) designates adenoid vegetations, meaning the hypertrophy of the pharyngeal tonsil located in the nasopharynx, frequently found in children and responsible for chronic nasal obstruction. This structural term describes a lymphoreticular conformation adapted for early immune defense.
• Adenoidectomy — A surgical intervention consisting of the extirpation or resection of hypertrophied adenoid vegetations (commonly known as adenoids), located in the nasopharynx. This structural procedure is frequently used in children to eliminate severe respiratory obstructions, treat recurrent otitis, or correct obstructive sleep apnea.
• Aneresis — A rare congenital malformation or structural anomaly characterized by the partial or total absence of the anus, often associated with anal imperforation or the presence of abnormal rectal fistulas. Clinically and functionally, this severe bio-structural condition blocks the normal evacuation of fecal matter in the newborn, requiring emergency reconstructive surgical intervention immediately after birth.
• Anoproctia — A rare pathological condition or congenital structural malformation characterized by the absence of a normal anal opening or by the abnormal fusion of the anal canal with the rectum, blocking digestive transit. In clinical terminology, the term is associated with anorectal imperforation and requires immediate surgical correction after birth to restore patency and physiological evacuation of meconium.
• Appendicostomy — A surgical procedure consisting of bringing the vermiform appendix to the surface of the abdominal wall and opening it to create a therapeutic stoma (also known as the Malone procedure). This technique is utilized to allow anterograde enemas directly into the colon in cases of chronic fecal incontinence or severe neurogenic constipation.
• Aproctia — An extremely rare congenital malformation characterized by the complete absence, imperforate state, or congenital structural occlusion of the anal orifice (anus). This anatomical phenomenon requires emergency pediatric surgical intervention immediately after birth to create an artificial elimination pathway and restore normal physiological functions.
