【Abstract】 ObjectiveTo investigate the value of splenic artery preocclusion applied to laparoscopic splenectomy. MethodsSplenic artery preocclusion was performed in 46 patients during splenectomy. Parts of ligamenta gastrocolicum and splenogastric ligament were dissociated after establishment of the operation space. The vascular sheath of spleen was dissected at the superior margin of the pancreas, and the splenic artery was ligated after being dissociated. Then the perisplenic ligaments and splenic hilus were dissociated till the spleen were removed. ResultsLaparoscopic splenectomy was completed successfully in the 46 patients. The operative duration was 1.5～4.5 hours. , and the intraoperative blood loss was 150～450 mL. No arterial active bleeding occurred during and after operation. Deep vein thrombosis of lower extremities , ascites due to hypoproteinemia and pulmonary infection were observed in 1 case, 9 cases and 1 case respectively, and all these cases were improved after treatment. No reduction or slight increase of postoperative hemoglobin level was observed in 32 patients compared to the preoperative hemoglobin level. No perioperative death occurred. ConclusionSplenic artery preocclusion can reduce the intraoperative blood loss and ensure the safety of laparoscopic splenectomy.
