嚥下魚骨による膀胱周囲膿瘍の1例

Abstract

A 58-year-old house wife was seen with the lower abdominal pain, frequent urination and feeling of residual urine. Cystoscopy revealed a ring-form protrusion at the dome of the bladder associated with hyperemia of the covering mucosa. Laparotomy disclosed an inflammatory mass attached to the terminal ileum and to the bladder. On dissection of the abscess, a fish bone was found. All the abscess wall was removed together with a part of the bladder. Serosa of the ileum where the fish bone migrated outside was closed with a few interrupted sutures. No resection of the intestine was needed. The patient recovered uneventfully. Histological findings of the removed specimen were compatible with non-specific granuloma.
