ABSTRACT:
A method for placing a feeding tube in a patient. The method includes the step of providing a needle defining a channel therethrough, the needle being constructed for insertion through an abdominal wall of a patient and having a distal end portion and a proximal end portion. The distal end portion of the needle is inserted through an abdominal wall of a patient. An endoscope constructed for insertion through the channel defined through the needle is provided and inserted through the channel defined through the needle. An external environment of the distal end portion of the needle is viewed using the endoscope in order to determine whether the distal end portion of the needle is positioned within a preselected portion of a gastrointestinal tract of a patient. A dilating device having a proximal end portion and a distal end portion is provided. The dilating device defines a channel therethrough. The dilating device is placed such that the needle is positioned within the channel defined through the dilating device. The dilating device is passed along the needle such that the distal end portion of said dilating device passes through an abdominal wall of a patient and into a preselected portion of a gastrointestinal tract of a patient. The needle is then removed from the patient. A feeding tube defining a channel therethrough is provided. The feeding tube has a proximal end portion and a distal end portion. The feeding tube is positioned such that the distal end portion of the feeding tube is positioned within the channel defined through the dilating device and the feeding tube is urged into a gastrointestinal tract of a patient. The dilating device is then removed from the patient.
