Percutaneous abscess drainage in XXXX : technical success and short- and long-term outcomes during 14 years.

PURPOSE: To determine technical success with percutaneous abscess drainage (PAD) in @entity1 with @entity30 during 14 years. MATERIALS AND METHODS: Medical records of 32 @entity1 with @entity30 who underwent PAD from 1985 to 1999 were reviewed. Results of abscess drainage and nature of subsequent surgical procedures were recorded. Factors assessed included postoperative or spontaneous nature of the abscess, documentation of a proved @entity292 , history of occurrence of prior @entity733 , duration of @entity30 , and use of @entity134 treatment. Technical success was defined as complete abscess drainage. Short-term success was defined as avoidance of surgery within 60 days of drainage. Long-term success was defined as avoidance of surgery beyond the initial 60-day period. Short-term avoidance of surgery was assessed as a predictor of the need for surgery in the long term. Statistical analysis was performed with the chi(2) test to evaluate predictors of short-term success and to assess short-term success as a predictor of long-term success. RESULTS: The technical success rate was 96%. In 16 (50%) of 32 @entity1 , the need for surgery in the short term was avoided, and surgery was more likely to be avoided in @entity1 with postoperative @entity733 than in those with spontaneous @entity733 (P =.07). At long-term follow-up, short-term avoidance of surgery did not significantly increase the likelihood of need for surgery in the long term, which occurred in nine of 16 short-term successes versus five of 15 short-term failures (P =.55). Recurrent @entity733 occurred in seven (22%) @entity1 , a rate comparable to that with surgical abscess drainage; four (44%) of nine cases of re-drainage were successful. CONCLUSION: PAD has a high technical success rate of 96%. Half of @entity1 may avoid surgery in the short term.
