Objective: To investigate the values of clinical application of lower abdominal aorta balloon occluding in the pelvic and sacral tumor resection.
Method: From January 2004 to January 2010, 137 patients were diagnosed as sacral or pelvic tumors and underwent surgery in our institution. Forty-five patients underwent resection combined with lower abdominal aorta balloon occluding to control hemorrhage (balloon occluding group), the remaining 92 patients underwent conventional resection (conventional therapy group). We compared operative time, intraoperative hemorrhage, the amount of blood transfusion, postoperative complications, mean hospital stay as well as rates of tumor recurrence or metastasis at 3 years.
Results: En-bloc resection was performed in 93.3% (42/45) patients in balloon occluding group while the conventional therapy group was 78.2% (79/92). The balloon occluding group showed significantly shorter mean operating time, lower blood loss, lower blood transfusion, and lower postoperative drainage volume than did the conventional therapy group. The two treatment groups showed no significant difference in mean hospital stay, frequency of postoperative complications or rates of tumor recurrence or metastasis at 3 years.
Conclusion: The application of lower abdominal aorta balloon occluding to control hemorrhage during the surgery contributes to a more clear operation field, less operation time as well as less blood loss and blood transfusion. Moderate prolong of the occluding duration can improve the safety of the surgery and contribute to more radical resection of the tumor without increase of the risks for complications.
