[Hepatic blood flow decreases during laparoscopic cholecystectomy].
Changes of median hepatic venous blood flow (MHVBF) and left portal venous blood flow (Lt. PVBF) were measured continuously in 31 patients undergoing elective laparoscopic cholecystectomy (LC) by using transesophageal echocardiography (TEE). The patients were anesthetized with inhalation and epidural anesthesia. MHVBF and Lt. PVBF decreased from preoperative level of 317 +/- 61 ml.min-1, 522 +/- 86 ml.min-1 to 73 +/- 22 ml.min-1, 98 +/- 28 ml.min-1 after inflation with high pneumoperitoneum pressure and they recovered by deflation. These findings suggest that hepatic blood flow decreases by increased intraperitoneal pressure.
