Abstract

A subepithelial mass is a common finding during endoscopic procedures. Endoscopic ultrasound (EUS) is an important diagnostic modality in the evaluation of subepithelial lesions of the gastrointestinal tract. EUS is the diagnostic test of choice to assess the size, margins, the layer of origin, echotexture, and to differentiate between an intramural and extramural lesion. However, the EUS imaging lacks the specificity. EUS-guided fine needle aspiration (EUS-FNA) or core biopsy can help establish a tissue diagnosis and potentially characterize malignant risk. The aim of this article is to review the diagnosis and management of the most common subepithelial gastric lesions with an emphasis on the role of endoscopic ultrasound.

Abstract in Croatian

ULOGA ENDOSKOPSKOG ULTRAZVUKA U EVALUACIJI SUBEPITELNIH LEZIJA U ŽELUCU ----- Subepitelni tumor, ili u literaturi češće spominjani termin »submukozni« tumor, je prominencija sluznice gastrointestinalnog sustava pokrivena normalnim epitelom koja se često nalazi tijekom endoskopskih pretraga probavnog trakta. Endoskopski ultrazvuk (EUZ) je značajna dijagnostička metoda u evaluaciji ovih lezija. EUZ-om je moguće definirati da li se radi o intramuralnoj masi ili kompresiji izvana, procjeniti veličinu i rubove lezije, ehoteksturu, vaskularizaciju, te odrediti sloj stjenke iz kojeg raste. Budući da EUZ nije dovoljno specifičan u određivanju etiologije subpitelnih lezija, tankoiglena aspiracija ili biopsija pod kontrolom EUZ-a može nam pomoći u postavljanju dijagnoze i određivanja malignog potencijala. Cilj ovog članka je pregled najčešćih subepitelnih želučanih lezija, njihova dijagnostika i terapija, s naglaskom na ulogu EUZ-a.
