Successful ex-vivo probe-based confocal laser endomicroscopy of a superficial nonampullary duodenal epithelial tumor with dripping of food additives: a case of tubular adenocarcinoma

摘要

Endoscopic qualitative diagnosis of a superficial nonampullary duodenal epithelial tumor (SNADET) is difficult.The accuracy of biopsy sampling for SNADET also is notperfect.1At present, endoscopic diagnosis of SNADETs isstill controversial, and early establishment of standardsfor endoscopic diagnosis is awaited. Meanwhile, probebased confocal laser endomicroscopy (pCLE) is an innovative endoscopic technique that enables“optical biopsy”byenabling real-time imaging of biotissue by the intravenousinjection of a fluorescent dye.
