Core Tip
Core tip: Good quality biopsy specimens are required for reliable diagnosis of early neoplasia in patients with Barrett’s esophagus. It remains controversial whether the use of jumbo forceps provides an advantage over large-capacity forceps. We compared the sampling quality using four different biopsy forceps. Biopsies were obtained using a diagnostic endoscope during a single endoscopy. We found a significantly higher proportion of adequate biopsy samples with jumbo forceps as compared to the three large capacity forceps. Thus, jumbo biopsy forceps, when used with a diagnostic endoscope, provide more adequate specimen as compared to large-capacity forceps.
