| Summary: | BACKGROUND:
Data on percutaneous drainage followed by observation for diverticular abscess is scant.
OBJECTIVE:
The aim of this study is to assess outcomes of percutaneous drainage alone in the management of peridiverticular abscess.
DESIGN:
This is a retrospective study from a prospectively collected database.
SETTING:
This study was conducted in a high-volume, specialized colorectal surgery unit.
PATIENTS:
All patients with a diverticular abscess of at least 3 cm in diameter, treated between 2001 and 2012, who had prohibitive comorbidities or refused surgery after percutaneous drainage were included.
MAIN OUTCOME MEASURES:
The primary outcome measured was the treatment of diverticular abscess with percutaneous drainage alone.
RESULTS:
A total of 18 patients (11 surgery refusal, 7 comorbidity) were followed up until death, surgery for recurrent diverticulitis, or for a median of 90 (17–139) months. The median abscess size was 5 (3.8–10) cm, and the location was pelvic in 8 cases and intra-abdominal in 10. The mean duration of drainage was 20 ± 1.3 days, with the exception of 2 patients who only had aspiration of the abscess because of technical difficulty in drain placement. Three patients died of preexisting comorbidities between 2 and 8 months after percutaneous drainage. Seven of the surviving patients (7/15) experienced recurrent diverticulitis; 3 of these patients underwent surgery between 7 months and 7 years after the index percutaneous drainage. Of the remaining 4 cases of recurrence, one abscess was treated with repeat percutaneous drainage alone and 3 patients had uncomplicated diverticulitis treated with antibiotics. There were no significant associations between long-term failure of percutaneous drainage and the location of the abscess ( p = 0.54) or previous episodes of diverticulitis ( p = 0.9).
LIMITATIONS:
This study was limited because of its retrospective nature, its nonrandomized design, and its small sample size.
CONCLUSIONS:
Percutaneous drainage alone was successful in avoiding surgery in the majority of this selected patient population with sigmoid diverticular abscess. Future studies should assess the appropriate indications for a more liberal use of percutaneous drainage not followed by elective surgery. |
