Article Synopsis
- The study evaluates the effectiveness of macroscopic on-site evaluation (MOSE) during endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) in diagnosing solid lesions, particularly focusing on histological core sample adequacy.
- Conducted across 16 medical centers in Egypt, Iraq, and Morocco, the study involved over 1000 patients and revealed that a significant majority of biopsied samples were adequate for histological evaluation, demonstrating a high diagnostic yield.
- Results indicated that FNB needles performed best in terms of sensitivity and sample quality, highlighting the potential of MOSE as a valuable alternative to traditional rapid on-site evaluation methods.
The allelic discrimination of IFNL3-(rs12979860 C > T) polymorphism reveals ambiguous associations with the effectiveness of oral HCV treatment. Solitary intra peripheral-blood-mononuclear-cells (PBMCs) HCV-RNA antisense-strands are independently detected in naïve and experienced cases regardless of viremia or hepatic-parenchymal alterations. We examined the frequencies of IFNL3-genetic variants with chronic-HCV-induced liver changes during the sustained virologic response (SVR) by evaluating the PBMCs- HCV-PCR after oral antiviral therapy.

However, in some patients, B2 and B3 do not join each other due to invasive hilar tumors; therefore, single-route drainage is insufficient. Here, we investigated the feasibility and efficacy of EUS-HGS through both B2 and B3 simultaneously in seven patients.
