Efficacy of medical thoracoscopy combined with fibrinolytic therapy in the treatment of complicated parapneumonic effusions and empyema

Table 4 Comparison of postoperative drainage, antibiotics, hospitalization, and costs between two groups

Group	Sample size (n)	Preoperative pleural effusion volume	Postoperative chest drainage time	Postoperative duration of fever
Group	Sample size (n)	G (%)	d, M [P25, P75]	d, M [P25, P75]
Medical thoracoscopy group	33	G1(27.3) G2(36.4) G3 (36.3)	6.0 [5.0, 7.0]	3.0 [1.0, 3.0]
Traditional treatment group	75	G1(22.7) G2(36.0) G3 (41.3)	7.0 [6.0, 9.0]	3.0 [2.0, 4.0]
Statistical value		Z=-0.577	Z=-3.607	Z=-2.220
P value		0.564	<0.001	0.026

Group	Sample size (n)	d, M [P25, P75]	d, M [P25, P75]	¥, M [P25, P75]
Medical thoracoscopy group	33	16.0 [13.0, 20.0]	19.0 [15.5, 23.0]	20257.2 [18530.0, 22479.5]

Note: Preoperative pleural effusion volume grading (G): G1: <500 ml, G2: 500–1500 ml, G3: >1500 ml. Postoperative chest drainage time, fever duration, intravenous antibiotic use duration, hospitalization duration and medical costs in the medical thoracoscopy group are presented as M [P25, P75] due to non-normal distribution
