The transparent cap and hood at the tip of the endoscope is a very useful device for biopsy, local injection, polypectomy, clipping, and laser irradiation treatment. But these device has demerit of narrowed visual field.
However, this device is sometimes hazardous on emergency endoscopy, or on turning the tip of the endoscope to observe the body and the cardia of the stomach. If the cap or hood at the tip of the endoscope equipped the capacity to slide in and out when necessary, this limitation would be overcome. We developed a cap which equipped this capacity. We modified the part of the O-ring of the sliding device MD-48809 (Sumitomo BL Co) which is already equipped to install on the tip of the endoscope. It slides freely when necessary. When pulled back, it provides wide visual field. When pushed forward, it facillitates placing clips on bleeding vessels. Using this device, we successfully stopped active bleeding of the remnant gastric stomal ulcer in a 57-year-old male.
