Abstract

AIM:

Evidence is lacking whether an abscess associated with anastomotic leak after an ileal pouch-anal anastomosis (IPAA) should be drained by transanal or CT-guided drainage. Therefore, the aim of this study was to compare outcomes after the two techniques for drainage.

METHOD:

Patients who underwent IPAA (1984-2009) and diagnosed with a pelvic abscess associated with an anastomotic leak were identified. The choice of operative or image-guided drainage was based on surgeon preference. Differences between patients undergoing transanal (group TA) and CT-guided drainage (group CT) were determined.

RESULTS:

Groups TA (n = 53) and CT (n = 18) had similar age (p = 0.3), gender (p = 0.3), body mass index (p = 0.6), steroid use (p = 0.4), albumin level (p = 0.9), ileostomy (p = 0.6), and follow-up time (p = 0.5). The size of the abscess was greater in group CT (p = 0.012). Two patients developed fistula at the CT-guided drainage site. Both healed after conservative treatment and drainage of associated gluteal abscess, respectively. Thirteen patients in group TA and three patients in group CT (p = 0.6) had failure of drainage and underwent surgery. The success rates for the procedures in terms of long-term pouch retention were 75.5% and 83%, respectively, for TA and CT. Groups TA and CT had similar bowel frequency (p = 0.9), incontinence (p = 0.6), urgency (p = 0.9), seepage (p = 0.6), pad usage (p = 0.1), quality of life (p = 0.9), and happiness with surgery (p = 0.9).

CONCLUSIONS:

There is a risk of fistula at drainage site after a CT-guided drainage of the pelvic abscess associated with anastomotic leak following IPAA. Transanal and CT-guided drainage are equally effective and result in similar long-term pouch-related outcomes.
