Clinical study of free auxiliary device of hand assisted laparoscopic splenectomy and intraoperative autologous splenic blood transfusion

Abstract

Objective To investigate the feasibility and advantage of hand assisted laparoscopic splenectomy for giant spleens without auxiliary device and the clinical value of intraoperative autologous splenic blood transfusion.Methods From October 2007 to October 2011,48 cases of liver cirrhosis splenomegaly were analyzed retrospectively according to operation method including hand assisted laparoscopic splenectomy group with free auxiliary device (HALS) (n =30) and conventional laparoscopic splenectomy (CLS) (n =12),and they were divided into two groups:severe splenomegaly group (the length of the spleen more than 20 cm) and moderate splenomegaly (the length of the spleen less than 20 cm).The intraoperative bleeding,operation time,the spleen removal time and transit operation rate were compared in these patients.The blood transfusion machine was used for autologous splenic blood transfusion.Results Free auxiliary device saved at least 2000 yuan without affecting the maintenance of pneumoperitoneum during operation.There was no significant difference in the average blood loss between HALS group and CLS group [(88.1 ± 16.3) ml vs.(107.5 ± 11.6) ml,P ＞0.05].The average operation time was significantly shorter [(75.2 ± 13.3) min vs.(120.7 ± 20.5) min,P ＜ 0.05],and the spleen removal time was markedly shorter [(8.0 ±3.1) min vs.(25.2 ±2.8) min,P ＜0.05] in HALS group than in CLS group.The transit operation rate of severe splenomegaly (50％) was significantly higher than moderate splenomegaly (20％) (P ＜ 0.01),and the intraoperative bleeding too [(103.8 ± 25.0) ml vs.(70.4 ± 10.3) ml,P ＜0.01].Intraoperative autologous splenic blood transfusion significantly elevatedf hemoglobin level on the first day after operation [(2.07 ± 0.25) g/L,P ＜ 0.05].Conclusion HALS significantly facilitates the surgical procedure and reduces the operational risk,while maintaining the advantages of CLS.Hand-assisted laparoscopic splenectomy is a safe and effective technique especially for the management of severe splenomegaly.Intraoperative autologous splenic blood transfusion shows obvious special advantage in ascending hemoglobin.
