Background/purpose: The most common cause of conversion to laparotomy (open splenectomy) during laparoscopic splenectomy (LS) is bleeding from the splenic hilar vessels. Recently, the efficacy of Ligasure (a vessel-sealing system) as a safety device for sealing vessels and reducing intraoperative blood loss has been reported with various laparoscopic procedures. The objective of this report was to describe our techniques for minimizing bleeding during LS, characterized by the application of Ligasure (which reduces the number of clips and staples, and reduces unnecessary bleeding) and a splenic hilum hanging maneuver with a Diamond-Flex flexible retractor to obtain optimal exposure of the splenic hilum.
Methods: We have performed 87 LSs since February 1993, and have employed the Ligasure instead of metal clips and staplers since September 2003. We have also introduced the splenic hilum hanging maneuver paired with Ligasure use. We have performed this new LS in 30 consecutive adult patients presenting with idiopathic thrombocytopenic purpura (n = 14), benign splenic tumor (n = 5), lymphoma (n = 4), hereditary spherocytosis (n = 2), liver cirrhosis (n = 2), and other pathologies (n = 3). The splenic ligaments and vessels, including the splenic artery and vein, were divided using a 5-mm Ligasure instead of a clip or stapler. The splenic hilum was encircled and elevated, using a Diamond-Flex, to ensure better exposure in all patients.
Results: LS was successfully completed in 29 patients (97%), with only one conversion to open splenectomy. Mean blood loss for all patients with completed LS was only 21.6 ml (range 0-250 ml). Moreover, blood loss was not determinable (considered as 0 ml in this study) in 15 patients (52%). Mean spleen weight and operating time were 319.4 g (range 80-1605 g) and 143.4 min (range 90-180 min), respectively. No postoperative mortalities were encountered. Two patients experienced complications, including grade B pancreatic fistula and atelectasis, for an overall morbidity rate of 6.7%. Mean postoperative stay was 6.5 days (range 3-14 days).
Conclusions: LS using a Ligasure in combination with the splenic hilum hanging maneuver may reduce intraoperative blood loss.
