  • Title: EUS-guided drainage of pelvic abscess (with video).
    Author: Varadarajulu S, Drelichman ER.
    Journal: Gastrointest Endosc; 2007 Aug; 66(2):372-6. PubMed ID: 17643716.
    Abstract:
    BACKGROUND: Although pelvic abscesses have traditionally been drained by surgery or under radiologic guidance, a small subset of patients who are not candidates for these interventions require an alternate mode of drainage. OBJECTIVE: Evaluate the efficacy of EUS for drainage of pelvic abscesses that could not be drained under US or CT guidance. DESIGN: Prospective case series. SETTING: Tertiary referral center. PATIENTS: Four patients underwent EUS-guided drainage of pelvic abscesses that were not amenable for drainage by US and/or CT guidance. INTERVENTIONS: A 10F drainage catheter was deployed in the abscess cavity under EUS guidance in all patients. The catheters were flushed periodically until resolution of the abscess was confirmed by CT imaging. MAIN OUTCOME MEASUREMENTS: Resolution of a pelvic abscess on follow-up CT and improvement in clinical symptoms. RESULTS: A drainage catheter was successfully placed in all 4 patients. The mean size of the abscess was 68 x 72 mm. There were no procedure-related complications. One patient died of worsening congestive heart failure 48 hours after the procedure. The abscesses resolved in the remaining 3 patients within a mean duration of 6 days, with complete symptom relief. LIMITATIONS: A small number of patients and short duration of follow-up. CONCLUSIONS: EUS-guided placement of drainage catheter is a minimally invasive technique for draining pelvic abscesses that are within the reach of the echoendoscope.
