Percutaneous imaging-guided interventions for acute biliary disorders in high surgical risk patients

Table 6 Comparison between ultrasonography- and computed tomography-guided drainage procedures in patients with pathological intra-abdominal fluid collection

Type of collection	US-guided procedures		CT-guided procedures
	No. of procedures	Successful procedures	No. of procedures	Successful procedures
Bilomas	4	2 (50)	10	9 (90)
Abscess	6	3 (50)	8	7 (87.5)
Pancreatic pseudocysts	5	3 (60)	7	7 (100)
Total	15	8 (53.33)	25	23 (92)1

¹The success rates in patients drained by computed tomography (CT)-guidance were significant (P = 0.0145 < 0.05) compared with those drained under ultrasound guidance. US: Ultrasonography.
