#abdominal

• Abdomen — A major anatomical region located between the thorax and the pelvis, bounded superiorly by the diaphragm and inferiorly by the plane of the pelvic inlet. It contains the main organs of the digestive and urinary systems. In psychiatric and neurological semiology, the clinical examination of the abdomen is crucial for identifying somatopsychic correlations, such as hypochondriasis (somatic delusion focused on abdominal organs), digestive manifestations of severe anxiety, or altered abdominal cutaneous reflexes in pyramidal syndromes.
• Abdominal — Pertaining to the abdomen, relating to the abdomen, or located within this anatomical region. In psychiatric semiology, the adjective qualifies a wide range of dysfunctional clinical manifestations, such as 'abdominal aura' (a bizarre epigastric sensation preceding a temporal lobe epilepsy seizure) or 'abdominal migraine' (an idiopathic periodic manifestation, sometimes correlated with emotional lability in children). It also describes the localization of somatizations in anxiety-depressive disorders.
• Abdominalgia — A clinical term used to describe any form of pain localized within the abdomen. In psychiatric semiology and psychosomatic medicine, abdominalgia represents one of the most common somatic complaints, often being the clinical expression of a conversion disorder, generalized anxiety, or a masked depressive episode, where organic investigations reveal no structural lesion.
• Abdominocentesis — An invasive medical procedure consisting of the surgical puncturing of the abdominal wall using a trocar or needle, aimed at evacuating or analyzing fluids pathologically accumulated in the peritoneal cavity (ascites). In historical neuropsychiatric practice, the analysis of this fluid was used to differentiate true ascites from an imaginary pregnancy (pseudocyesis) or somatoform disorders with pronounced abdominal distension found in alienated patients.
• Abdominohysterectomy — A major surgical operation consisting of the total or partial extirpation of the uterus via an abdominal approach, performed through an incision in the belly wall. In clinical and psychiatric studies, this intervention is evaluated from the perspective of its profound psychosomatic impact, as the patient may develop severe post-operative depressive reactions, anxiety related to the loss of femininity, or somatoform sexual dynamic disorders.
• Abdominohysterotomy — A surgical procedure consisting of incising the uterine wall via a transabdominal approach (entering through the belly wall), primarily used for delivering a fetus (cesarean section) or removing intramural tumors. In historical psychiatric clinics, this maneuver was studied in relation to severe surgical shock or the occurrence of post-cesarean puerperal psychoses in emotionally predisposed patients.
• Abdominouterotomy — A synonymous terminological variant for 'abdominohisterotomie', denoting the surgical operation of incising the uterus via a transabdominal approach (cutting both the abdominal wall and the uterine wall). Used in Romanian medical literature during the neological transition period, the term is closely linked to the evolution of cesarean section techniques and the management of major gynecological complications, studied in correlation with acute abdominal surgical traumas and the incidence of puerperal psychoses.
• abs — (Automotive) An electronic automotive safety system that prevents vehicle wheels from locking during heavy braking, maintaining steering control; (sports, anatomy, colloquial) short form for abdominal muscles.
• Aerocoly — A digestive disorder manifested by the excessive accumulation of air or gas inside the colon, causing abdominal distension, flatulence, and colicky pain. This clinical phenomenon is often the result of aerophagia, increased bacterial fermentation, or intestinal motility disorders.
• Agenosomia — A severe congenital malformation of a teratological nature, characterized by the incomplete development or partial to total absence of external genital organs and the lower abdominal wall, frequently associated with visceral eventration. This severe structural anomaly is clinically investigated within fetal pathology and is commonly considered incompatible with long-term extrauterine survival.
• Appendicalgia — A clinical syndrome characterized by the presence of a localized pain in the right iliac fossa, occurring at the level of the vermiform appendix, without being accompanied by the typical acute or infectious signs of true appendicitis. It is often a functional or chronic manifestation requiring differential diagnosis.
• Appendicitis — An acute or chronic inflammation of the vermiform appendix, usually caused by a lumen obstruction due to the presence of fecaliths, lymphoid hyperplasia, or foreign bodies. This pathology represents one of the most common abdominal surgical emergencies, manifesting through intense pain in the right iliac fossa, nausea, and fever.
• Appendicocele — A rare herniary formation characterized by the protrusion and isolation of the vermiform appendix within a hernial sac (usually inguinal or femoral), clinically known also in the context of Amyand's hernia. This structural anomaly can progress to strangulation or local acute inflammation, requiring surgical treatment.
• Appendicolysis — A minimally invasive or open surgical procedure consisting of the release of the vermiform appendix from the inflammatory or cicatricial fibrous adhesions that block or distort it. This anatomical release intervention restores the organ's mobility and normal lumen, eliminating chronic pain.
• Ascites — The pathological accumulation of serous fluid (transudate or exudate) within the peritoneal cavity, manifested by a progressive increase in abdominal volume and a sensation of internal tension. This structural phenomenon frequently occurs as a major complication of liver cirrhosis, severe heart failure, kidney diseases, or certain intra-abdominal malignancies.
