Comparison of ultrasound- and CT-guided percutaneous drainage of abdominal and pelvic cyst and abscess

Objective: To compare the efficacy between ultrasound- and CT-guided percutaneous drainage of abdominal and pelvic cyst and abscess. Methods: The puncture frequency of ultrasound-guided (56 patients) and CT-guided (45 patients) percutaneous drainage of abdominal/pelvic cysts and abscesses was compared. Results: Sixty-three punctures were made using ultrasound-guided drainage of 58 cysts or abscesses in 56 patients. Seventy-seven punctures were made using CT-guided drainage of 45 cysts or abscesses in 45 patients. Conclusion: Ultrasound-guided percutaneous drainage is more effective and safer than CT-guided drainage of abdominal/pelvic cysts and abscesses. (authors)
