Drainage of deep pelvic abscesses using therapeutic echo endoscopy.
OBJECTIVE
The purpose of this study was to evaluate the clinical efficacy of endosonographically guided transrectal aspiration and drainage by plastic stent of deep pelvic abscesses, using a therapeutic echo endoscope device.


METHODS
Between September 2000 and June 2001, 12 patients (nine men, three women, mean age 67 years) were treated for a perirectal or a pelvic abscess using an endoscopic ultrasound (EUS) technique. The drainage of these fluid collections was performed under EUS guidance, using therapeutic EUS scopes with a large working channel.


RESULTS
No major complication occurred during this study. Transrectal stent insertion succeeded in nine patients. In three patients, only aspiration was possible. Among the nine patients in whom a stent was successfully introduced into the fluid collection, complete drainage without relapse was achieved in eight patients (mean follow-up 10.6 months, range 6-14 months). The stent was removed endoscopically after 3 to 6 months. Drainage was incomplete in one patient (with a large abscess, diameter > 8 cm), who subsequently underwent surgical drainage. However, two out of the three patients in whom aspiration alone was performed developed a recurrence of the abscess and required surgical treatment.


CONCLUSIONS
EUS-guided drainage of deep pelvic abscesses could offer an alternative treatment to surgery in the management of these postoperative complications.
