[Infection of submucosal tumor after endosonography-guided needle biopsy].

Abstract

Endosonography fine needle guided aspiration (EUS-FNA) biopsy is an interesting technique for the diagnosis of suspected gastrointestinal lesions, and is rarely complicated by infection. We report one case of severe infection after EUS-FNA of benign oesophageal leiomyoma, leading to an oesophagectomy. Recent studies about this technique described only infectious complications after biopsy of cystic lesions. They also show that EUS-FNA may misdiagnose leiomyosarcoma. Our report confirms these data, and relates a hitherto non-reported complication, i.e. the infection of a non-cystic lesion.
