Re: Forceps-related endoscopic transpapillary biliary biopsy programmes, reply: endoscopic biopsy techniques for proximal biliary strictures.

We read the paper by Meng et al. (1) entitled “Accurate biopsy of bile duct without destroying duodenal papilla” with great interest. They described a new technique to perform endoscopic biopsy in a 75-year-old male with a biliary stricture, which was presumed to be a malignancy, in the hilar region. They used a 7-Fr dilatation catheter (COOK, Winston-Salem, North Carolina, USA) and inserted it into the bile duct and across the stenosis along a guidewire. The withdrawal of the guidewire was followed by the insertion of a 1-mm SpyBiteTM forceps (Boston Scientific, EI Coyol, Alajuela, Costa Rica) through a dilatation catheter. When the tip of SpyBiteTM passed the top, the tissue was grasped. We believe that this technique is highly effective to make a histopathological diagnosis.
