Abstract

BACKGROUND/AIMS
Anisakiasis is frequent in Jeju Island because of the people's habit of ingesting raw fish. This study evaluated the clinical characteristics of patients with small bowel anisakiasis and compared them with those of patients with gastric anisakiasis.
METHODS
We retrospectively reviewed the medical records of 109 patients diagnosed with anisakiasis between May 2003 and November 2011.
RESULTS
Of the 109 patients diagnosed with anisakiasis, those with suspicious anisakiasis (n=38) or possible anisakiasis (n=12) were excluded. The age and gender distributions did not differ between patients with small bowel anisakiasis (n=30; age, 45+/-13 years) and those with gastric anisakiasis (n=29; age, 46+/-10 years). The mean duration of hospitalization was 5.4+/-4.3 days for patients with small bowel anisakiasis and 0.5+/-1.7 days for patients with gastric anisakiasis. Small bowel anisakiasis was accompanied by leukocytosis (76.7% vs 25.5%, p=0.003) and elevated C-reactive protein levels (3.4+/-3.2 mg/dL vs 0.5+/-0.3 mg/dL, p=0.009). Contrast-enhanced abdominopelvic computed tomography showed small bowel wall thickening with dilatation in 93.3% (28/30) of patients and a small amount of ascites in 80.0% (24/30) of patients with small bowel anisakiasis.
CONCLUSIONS
Compared with gastric anisakiasis patients, small bowel anisakiasis patients had a longer hospitalization time, higher inflammatory marker levels, and small bowel wall thickening with ascites.
