Article Synopsis
- The report discusses two patients diagnosed with gastric linitis plastica (GLP) using endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) with a Franseen-tip needle.
- Traditional methods like conventional endoscopy and bite-on-bite biopsies failed to provide a diagnosis, but EUS-FNB successfully obtained histopathological samples.
- The findings suggest that EUS-FNB is a safe and effective technique for diagnosing GLP, especially when other methods are inadequate.
Article Synopsis
- Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is a technique used for accurate pathology assessments in patients suspected of having pancreatic cancer.
- The study compared the effectiveness of three needle types in collecting histological tissue samples from pancreatic tumors, finding no significant differences in patient characteristics across groups.
- Results indicated that the 19-gauge Franseen needle collected significantly more tissue samples compared to the 19-gauge conventional and 22-gauge Franseen needles, enhancing the potential for precise diagnoses and genomic profiling.
Article Synopsis
- - Accurate genotyping of hepatitis C virus (HCV) is crucial for effective treatment, especially in patients with complex infections.
- - A 44-year-old Japanese man with hemophilia A was misdiagnosed with HCV genotypes 2b and 1b, when he actually had genotype 4, highlighting limitations in some testing methods.
- - It's essential to be cautious with HCV genotyping, particularly for patients who have received certain blood products or were infected outside Japan, as some tests may not identify genotype 4.
Background And Aim: During endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNB), Franseen needles can help collect sufficient tissue to permit histopathological assessment. However, its efficacy might be limited by the size of the targeted lesion. This study aimed to evaluate the feasibility of histopathological assessment of small solid pancreatic lesions using a 22-gauge Franseen needle during EUS-FNB.
