摘要
Method for implanting a percutaneous endoscopic jejunostomy tube in a patient and access needle for use in the method. In one embodiment, the method comprises the steps of (a) providing an access needle wherein the distal end of the stylet extends distally for an appreciable distance beyond the distal end of the cannula; (b) inserting the stylet, but not the cannula, into the jejunum; (c) grabbing the stylet with an endoscopically-positioned snare; (d) anchoring the jejunum against the abdominal wall of the patient using the snared stylet; (e) loosening the snare slightly while advancing the cannula into the jejunum and into the loosened snare; (f) tightening the snare around the cannula; (g) removing the stylet from the cannula; (h) inserting a guide wire or suture through the cannula and into the jejunum; and (i) proceeding in the conventional fashion to implant a PEJ tube into the patient using the guide wire or suture.
