“…Hydropic degeneration, a reversible lesion found in the specimens analyzed in this study, may be explained mainly by decreased portal blood flow during exposure to pneumoperitoneum, either by vascular compression or decreased venous return due to the high intra-abdominal pressure 19 . The lesions found in both postoperative periods (POD3 and POD7) are in agreement with those reported in previous studies, in which the liver had periods of ischemia and reperfusion [19][20][21] . In addition to ischemic events during gas insufflation, other factors, such as the use of anesthetic drugs and the presence of toxins, also trigger vacuolar degeneration.…”

“…Changes in liver blood flow are also associated with the sympathetic and humoral systems, triggered by hypercapnia and by increased intraperitoneal pressure 10 . The use of anesthetic drugs reduces cardiac output and blood supply to the liver 19 . These hemodynamic changes are followed by changes in hepatic functions.…”

“…İAB artışında hemodinamik belirtilerin ortaya çıkmasından çok önce viseral dolaşımın bozulduğu gösterilmiştir. [13][14][15] Çocuk cerrahisinde artmış İAB'nin zararlı etkileri ilk olarak Gross tarafından karın ön duvarı defektli hastaların tedavisinde bildirilmiş ve evreli onarım önerilmiştir. [16] Sonrasında İAB kontrolü altında primer kapatma yıllar içinde daha sık-lıkla kullanılmaya başlanmıştır.…”

“…IAH causes a dose-related decrease in abdominal blood flow including the mesenteric artery, the hepatic artery, the portal veins and the renal artery [46,[50][51][52][53][54]. The threshold of IAP causing reductions in regional abdominal blood flow has been shown to vary between 8 and 20 mm Hg and probably reflects the different measurement techniques used (Doppler flow probes, transit-time flow probes) and subjects studied (animals, humans) [46,53].…”
