Abstract: An endoscopy system can include or use an endoscopic overtube, sized and shaped for insertion into a patient esophagus towards a patient duodenum. The overtube can include and access lumen providing an inner diameter to receive and pass a cholangioscope therethrough. The distal portion of the overtube can include or use a side port sized and shaped to permit lateral exit of a distal portion of the cholangioscope. Also, the overtube can include a ramp arranged to re-direct the distal portion of the cholangioscope from a longitudinal direction in the access lumen toward the lateral exit of the side port.
