The Clinical Research Of Bilateral Internal Iliac Artery Pre-treatment In Laparoscopic Radical Cystectomy To Control Intraoperatie Bleeding

Objective:To investigate the feasibility of bilateral internal iliac artery ligation in laparoscopic radical cystectomy to control intraoperatie bleeding.Methods:44T1-4a invasive bladder cancer patients in minimally invasive urology of Second Affiliated Hospital of Kunming Medical University were divided in to study g roup(n=21) and control group(n=23), during January2009to May2012.There was n-o statistical difference of preoperative age, weight, hemoglobin, and prothrombin time between two groups(P>0.05). Patients in study group were ligated the iliac artery bra nch during surgery; patients in control group received the traditional surgeries withou t ligating the iliac artery branch during surgery. The operative time, blood loss, compl ications and blood transfusion rate were involved in the result analysis.?Results:Study group:operative time150-200minutes, average203.81±60.91ml; blood loss100-350ml, average203.81±60.91ml; blood transfusion rate14.3%; no colon damage. Control group:operative time170-240minutes, average205.21±22.94ml; blood loss200-700ml, average329.59±91.98ml; blood transfusion rate34.8%;2colon damage cases. There is statistical differences in operative time and blood loss between two groups(P<0.01); no statistical differences in number of blood transfusion patients(P>0.05).Conclusion:Bilateral internal iliac artery ligation in laparoscopic radical cystectomy can shorten the operative time, reduce blood loss, lower transfusion rates and reduce complication effectively. Ligation of the internal iliac artery does not lead to complications related to pelvic organs and buttock muscles.
