Background. Guided percutaneous drainage (GPD) is used in the manageme
nt of posttraunatic empyema thoracis; however, its equivalence to deco
rtication has not been evaluated. Methods. We retrospectively reviewed
the records of 72 patients who underwent GPD and nine who were treate
d with decortication. Results. No primarily GPD-managed empyemas neces
sitated a subsequent thoracotomy. The size and number of fibrinopurule
nt loculations treated by each technique were equivalent. Sterile puru
lent collections were found in 55.6% of decortication-treated patients
and in 33% of Patients who underwent GPD. Intrapleural analgesia was
administered to 71.4% of decortication-treated patients and 28.6% of G
PD-treated patients. Five patients undergoing decorticatian required i
ntensive care unit monitoring after operation (average, 2.8 days), com
pared with no GPD-treated patients. The catheter was left in place at
discharge in 41.6% of GPD-treated patients and was removed on an outpa
tient basis. Conclusions. The efficacy of GPD in handling loculated pl
eural space infections equals that of decortication. An intensive care
unit slay is avoided. The ability to discharge patients with external
drainage catheters and the decreased requirement of pain control shou
ld reduce the number of inpatient hospital dalls. GPD is an effective
first-line approach Sor posttraumatic empyema thoracis.
