Transrectal and Transvaginal Sonographic Intervention of Infected Pelvic Fluid Collections

Abstract

Infected pelvic fluid collections are relatively common particularly after abdominal or pelvic surgery or in patients suffering from benign intestinal disease such as diverticulitis, appendicitis, or Crohn's disease. Historically the treatment of pelvic abscess has been either laparotomy with lavage or blind surgical incision and drainage through the rectal or vaginal wall. More recently, computed tomography and ultrasound-guided percutaneous drainage has become the procedure of choice, when feasible, for the treatment of pelvic abscess. However, many deep pelvic collections are not amenable to percutaneous technique. Transrectal or transvaginal ultrasound-guided abscess drainage is a safe and effective method used in the treatment of deep pelvic abscesses. The purpose of this article is to review the techniques, patient selection, pre- and post-procedural care, and monitoring aspects of transrectal or transvaginal ultrasound-guided drainage.
