Technologies are described for an endoscopic duct clearing system. A cannula can be shaped to pass through an endoscope within an esophagus, into a duodenum, and through an incision in a duodenal papilla. A capture basket may be deployed from a distal end of the cannula. A hand control at the proximate end of the cannula may be operable to position the distal end of the cannula from outside the endoscope into proximity of blockage material. A suction line may be coupled from a suction source to the proximate end of the cannula. A suction control may be coupled to the suction source. The suction control may be operable to adjust a level of suction drawn by the suction source through the distal end of the cannula. The suction control may be adjusted to draw the blockage material against or into the cannula for removal from the patient.
