ObjectiveTo investigate the clinical efficiency of pelvic and sacrum tumor surgery using sizing balloon occlusion of the lower abdominal aorta. MethodsFrom January 2005 to June 2011, 156 patients were diagnosed to have sacrum or pelvic tumor and underwent surgery in our institution. Temporary balloon occlusion of abdominal aorta was used in 51 patients during the resection of sacrum and pelvic tumors (balloon group). Another 105 patients received the traditional surgery resection (control group). The results of the whole operation time, the volume of blood loss and transfusion, the complication and the total days of stay in hospital in the two groups were compared with each other. ResultsAfter the abdominal aorta was occluded, 92.2% of the patients in the balloon group had holistic resection or edge resection, while the number was 86.7% for the control group. In the balloon group, the average operation time was (171.96±65.16) minutes, the average intraoperative blood loss was (746.86±722.73) mL, and the blood transfusion was (411.76±613.73) mL. The postoperative lead flow was (294.50±146.09) mL, and the postoperative tube removal was within (2.98±1.07) days. Improvement of patients'condition was significantly better than the control group (P<0.05). No significant difference was found in the total days of stay in hospital and the postoperative complications between the two groups (P>0.05). ConclusionUsing abdominal aorta occlusion can effectively control intraoperative hemorrhage, and show the operation field clearly. It also can reduce operation time and control the blood transfusions. Appropriately extended balloon blocking time can obviously improve the tumor removal rate and the safety of the operation.
ObjectiveTo explore the value of the long time lower abdominal aorta balloon block technology in the pelvis or sacrum tumor surgery. MethodsFrom January 2005 to June 2013, the sacrum or pelvic tumor patients underwent the long time lower abdominal aorta balloon block technology in the Orthopedics Department of West China Hospital of Sichuan University were enrolled. According to the balloon blocking time, patients were divided into A (<90 mins), B (90 to 180 mins), and C (>180 mins) groups. The intraoperative blood loss, blood transfusion amount, average lengths of hospital stay, postoperative volume of drainage, and postoperative complications were compared among the three groups. ResultsA total of 78 patients were included, of which 21 were in group A, 38 were in group B and 19 were in group C. All patients received en bloc resection, and did not experience intraoperative balloon shift and abdominal aorta flow leakage. Comparing the three groups, there were significant differences in intraoperative blood loss (P=0.026) and average lengths of hospital stay (P=0.021). Further pairwise comparison showed the intraoperative blood loss and average lengths of hospital stay in group C were significantly higher than those in group A and group B. In addition, there were no statistical differences among the three groups in blood transfusion amount, postoperative volume of drainage and postoperative complications. ConclusionIn the pelvis and sacrum tumor surgery, extending the time of abdominal aorta balloon block can reduce bleeding, save blood, increase the safety of surgery without increasing in postoperative complications.
