Endoscopic Ultrasound-Guided Transrectal Pelvic Abscess Drainage (EUS-PAD) - Bridging to Surgery: Report of Two Cases.

 Currently, the methods for drainage of pelvic abscess primarily use computed tomography- or ultrasound-guided percutaneous drainage or surgical drainage. Endoscopic ultrasound-guided pelvic abscess drainage (EUS-PAD) is an alternative, minimally invasive tool to drain an abscess, localized close to the rectum or left colon, and therefore not accessible by other means.  We report on the success of endoscopic ultrasound-guided drainage of peridiverticulitic abscess based on the two cases presented here.
