title: Conversion from external nasobiliary drainage to internal drainage using endoscopically available scissor forceps.
abstract: Endoscopic nasobiliary drainage may cause undue stress, such as pharyngeal discomfort. We converted external drainage to internal drainage by cutting the external drainage tube with endoscopically available scissor forceps. Endoscopic nasobiliary drainage tubes were cut in the vicinity of the papilla using scissor forceps in 4 patients. The drainage tube was successfully cut in all patients. The tube was left for short-term internal drainage in 3 patients until the operation or endoscopic treatment was performed. The remaining patient with pancreatic head cancer was followed as an outpatient and the tube stent was occluded 62 days after cutting. Although further studies using a larger number of patients are needed, our procedure is thought to be beneficial to patients undergoing endoscopic nasobiliary drainage.
