Retrospective review of percutaneous abscess drainage (PAD) of 335 abscesses in 323 consecutive patients was undertaken. Particular attention was directed to body location, associated organ system, communications and fistulae, and to the underlying immunologic status of the patient. One-year follow-up was available in all patients. Overall, the cure rate was 62.4% (209 of 335 abscesses), with a failure rate of 8.95% (30 of 335 abscesses). There were 14.2% (46 of 323 patients) deaths in the follow-up period, of which 4.6% (15 of 323 patients) were believed attributable to sepsis or septic complications. The overall complication rate was 9.8% (33 of 335 abscesses), most of which were minor in nature. For the patient exhibiting immunocompromise, representing 53.1% (172 of 323 patients) of the patient population, the cure rate was 53.4% (95 of 178 abscesses), which was significantly lower than the cure rate of 72.6% (114 of 157 abscesses) for the immunocompetent patient population (n = 151) (P less than .001). The recurrence rate was 2.1% (seven of 335 abscesses), with all recurrences within 3 months of initial drainage. PAD is effective and permanent treatment for both immunocompromised and immunocompetent patients.

- "The original criteria for PCD were limited to well-defined unilocular abscesses and multiple catheters for multilocular abscess.30 Multilocular abscesses can be managed with a single catheter, because the loculi intercommunicate.29 "
ABSTRACT: Percutaneous aspiration of abscesses under ultrasonography (USG) and computer tomography (CT) scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD) has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome. Twenty-nine patients with dorsolumbar spondylodiscitis without gross neural deficit with psoas abscess of size >5 cm were selected for PCD. It was done as a day care procedure under local anesthesia. Sequentially, aspiration followed by guide pin-guided trocar and catheter insertion was done without image guidance. Culture sensitivity was done and chemotherapy initiated and catheter kept till the drainage was <10 ml for 48 hours. Outcome assessment was done with relief of pain, successful abscess drainage and ODI (Oswestry Disability Index) score at 2 years. PCD was successful in all cases. Back and radicular pain improved in all cases. Average procedure time was 24.30 minutes, drain output was 234.40 ml, and the drainage duration was 7.90 days. One patient required surgical stabilisation due to progression of the spondylodiscitis resulting in instability inspite of successful drainage of abscess. Problems with the procedure were noticed in six patients. Multiple attempts (n = 2), persistent discharge (n = 1) for 2 weeks, blocked catheter (n = 2) and catheter pull out (n = 1) occurred with no effect on the outcome. The average ODI score improved from 62.47 to 5.51 at 2 years. Clinically guided PCD is an efficient, safe and easy procedure in drainage of psoas abscess.Indian Journal of Orthopaedics 03/2014; 48(1):67-73. DOI:10.4103/0019-5413.125506 · 0.64 Impact Factor

- "Subsequently, it was demonstrated that the effectiveness and safety of PAD [8, 18–20], which over the last 30 years, made the transition from a revolutionary to a routine procedure, replacing open surgical drainage, except in the most difficult or inaccessible cases. Using univariate analysis, several authors have identified the factors predictive of the failure of PAD, including enteric fistulae, multiple or loculated abscesses, large abscesses, necrotic tissue, and pancreatic localization [3, 8, 11, 21–24].

ABSTRACT: Purpose To improve the selection of patients for percutaneous abscess drainage (PAD) to treat postoperative intra-abdominal abscess after gastrointestinal surgery, we investigated the factors predictive of outcome. Methods Of 143 consecutive patients with symptomatic postoperative intra-abdominal abscess after a gastrointestinal tract resection, 104 who underwent image-guided PAD as the initial treatment were reviewed. We assessed the possible associations between successful PAD and patient-, abscess-, surgical-, and drainage-related variables, and investigated the success rates of PAD for patients with vs. those without the factors related to successful outcome. Results Based on monitoring for 1 year after PAD, the success rate of this procedure was 85.6 % (89/104). Multivariate analysis revealed that the interval between surgery and the onset of abscess (p = 0.0234) and a single abscess (p = 0.0038) were independently associated with a successful outcome. Single late-onset abscess resolved completely within 10 weeks in 91.4 % of these patients. Conclusions Despite new strategies aimed at preventing surgical site infection, PAD remains an important factor in the postoperative management of gastrointestinal surgery in Japan. Initial recognition of the day of onset and the number of abscesses are important prognostic factors.Surgery Today 02/2013; 43(10). DOI:10.1007/s00595-013-0504-x · 1.53 Impact Factor
