An 80-year-old female visited our hospital with the chief complaint of appetite loss. Blood tests revealed increased inflammatory response, and computed tomography showed a gallbladder tumor. She was admitted to our hospital because of suspected gallbladder cancer, and endoscopic retrograde cholangiopancreatography was performed. An endoscopic tapered sheath, EndoSheather, was inserted into the gallbladder along a guidewire. The inner catheter was removed, and a biopsy forceps was inserted through the outer sheath. Histopathologic examination of three biopsy specimens led to the diagnosis of gallbladder cancer. EndoSheather could readily pass through strictures, because there is almost no caliber difference between the inner catheter and the outer sheath. Since the biopsy forceps could be inserted through the inner sheath, repeated biopsies could be performed. EndoSheather was useful for transpapillary biopsy of gallbladder tumors.
