Study On Safety Of Hepatic Blood Inflow Occlusion Under CO₂ Pneumoperitoneum

ObjectiveStudy on safety of hepatic blood inflow occlusion under definition intraabdominal pressure and hepatic portal blocking time.Methods8 patients with hepatic hemangioma received laparoscopic hepatectomy from January to September in 2008 in Sheng Jing hospital.there were three men and five women.age among 42-64y,mean, (47.9±9.0) y. to keep intraabdominal pressure among 10-15 mmHg and vascular inflow occlusion by pringle's maneuver, liver function Including asparate aminotransferase(AST), alanine aminotransferase(ALT), total bilirubin(TBIL), albumin(ALB) were detected postoperative to analysis the liver damage; The patients were followed up for half month.ResultsThe laparoscopic hepatectomy was accomplished successfully in all patients without converting to open surgery. The operation time was 75-225 min, mean,(138.8±48.7)min; hepatic portal blocking time was 25-45 min, mean, (32.0±6.0)min; intraoperative blood loss was 200-1500 ml,mean, (575.0±562.5) ml; and the postoperative hospital stay was 3-10 d,mean, (6.6±2.2)d. all patients were followed up for half month, no one occurred hepatic failure.ConclusionUnder definite intra-abdominal pressure and hepatic portal blocking time, hepatic blood inflow occlusion is safe.
