Adherencias abdominales postoperatorias: patogénesis y técnicas actuales de prevención

Abstract: Las adherencias abdominales postoperatorias (AAP) ocurren en más del 90% de los pacientes sometidos a cirugía de abdomen; pueden causar dolor abdominal crónico, infertilidad femenina y obstrucción intestinal recurrente, que requieren intervenciones quirúrgicas que son causa de morbilidad y mortalidad, así como altos costos. La formación de AAP se debe a un desequilibrio entre la fibrinogénesis y la fibrinólisis a favor de la primera, asociada con hipoxia tisular secundaria a la agresión del peritoneo, también … Show more

“…PAAs are also more likely in obese, diabetic, hypertensive patients and patients with lipid metabolism disorders [ 14 ]. During the repair of the peritoneum by its mesothelial cells, the activation of vasoactive substances comes into play, as do cytokines that promote the processes of inflammation and coagulation, the activation of fibrinogenesis, the limitation of fibrinolysis, and the anti-inflammatory process in a hypoxic environment where adhesion fibroblasts are activated, causing excessive deposition of fibrin and mature collagen as well as supporting connective tissue [ [6] , [7] , [8] ].…”

“…The processes of PAA formation are well studied, and the evidence shows that PAA formation is mainly related to the activation of three interrelated biological processes: 1) the coagulation cascade, 2) fibrinolysis, and 3) the inflammation process, initiated by the lesion of the mesothelial cells of the peritoneum. These lead to the activation of fibrin formation by adhesion fibroblasts and the decrease in fibrinolysis in the fibrin-rich extracellular matrix, as well as to a hypoxic environment, favoring the maturation of fibrin and collagen through inflammatory cell activities, the activation and inactivation of signaling molecules, vasoactive substances, interleukins, and growth factors, among others [ [6] , [7] , [8] ].…”

“…Abdominal adhesion is a type of fibrosis that occurs commonly after abdominal surgery, resulting in clinically unfavorable symptoms such as nausea, vomiting, and even intestinal obstruction. [1] The prevalence of abdominal adhesion following major abdominal surgeries has been reported to be 63% to 97%. [2,3] Many existing literatures regarding abdominal adhesion were based on animal models.…”

“…El dolor abdominal debido a obstrucción intestinal es un motivo frecuente de ingreso a los servicios de urgencias en todo el mundo y corresponde al 2 -4 % de las consultas de urgencias, al 12 -16 % de los ingresos quirúrgicos de urgencia y a más de 300,000 cirugías de urgencia por año en los Estados Unidos [3][4][5] . La etiología más frecuente son las adherencias postoperatorias (60 -75 %) [5][6][7][8] , resultado del trauma quirúrgico que ocurre en el peritoneo visceral o parietal que forma un tejido fibroso que conectan superficies intrabdominales que normalmente están separadas, hasta en el 93 % de los pacientes con cirugía abdominal [7][8][9] .…”
