Psoas abscess in inflammatory bowel disease
Abstract:
The inflammatory bowel disease (IBD) is sometimes complicated by the development of a psoas abscess. We recently encountered three patients of IBD with psoas abscess. Two patients had Crohn's ileocolitis and one with ulcerative colitis. During 1979-1984, 23 patients with psoas abscess due to a variety of underlying disease processes were seen at our institution. At the same time period, 483 cases of Crohn's disease and 283 cases of ulcerative colitis were encountered. Therefore, of 766 patients with IBD only three were complicated by psoas abscess (incidence ratio = 0.6%). Thus, psoas abscess was a very rare complication of IBD in patients seen at our institution. In our series of 23 psoas abscess patients, IBD was not a major causative factor. Additionally, to our knowledge, psoas abscess complicating ulcerative colitis has not been reported previously.
Insights
Psoas abscess is a rare complication of inflammatory bowel disease (IBD), affecting only 0.6% of IBD patients in this study. Ulcerative colitis with psoas abscess was notably unreported before this case series.
Area of Science:
- Gastroenterology
- Infectious Disease
Background:
- Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, can present with extraintestinal manifestations.
- Psoas abscess, a collection of pus in the iliopsoas muscle, is a known but infrequent complication of various conditions.
Observation:
- This study reviewed cases of psoas abscess at an institution between 1979-1984.
- Three cases of IBD patients with psoas abscess were identified: two with Crohn's ileocolitis and one with ulcerative colitis.
- During the same period, 766 IBD patients were treated, yielding an incidence of 0.6% for psoas abscess complication.
Findings:
- Psoas abscess was a rare complication of IBD in the observed patient cohort.
- IBD was not identified as a primary causative factor in the majority of psoas abscess cases reviewed.
- This series includes the first reported case of ulcerative colitis complicated by psoas abscess.
Implications:
- The findings highlight the infrequent association between IBD and psoas abscess.
- The report expands the known spectrum of IBD complications, particularly concerning ulcerative colitis.
- Further research may be warranted to elucidate the specific mechanisms and risk factors for psoas abscess in IBD patients.
