Percutaneous drainage of large tuberculous iliopsoas abscess via a subinguinal approach: a report of two cases.

Abstract

Two patients who had large tuberculous abscesses that were successfully treated with percutaneous drainage alone are reported. A new approach, called the "subinguinal approach," was used. This new technique avoids the bowel loops and pelvic organs (which can be limitations when using the anterior abdominal approach) by inserting the catheter through the subinguinal portion of the psoas muscle into the abscess. Compared to the posterior approach, this technique is more comfortable for the patient (who prefers a supine position) and is not limited by the iliac bone. The technique, clinical course, and outcome are described.
