A replacement gastrostomy tube device is provided comprising a catheter shaft having an outer surface wall, with the shaft enclosing a feeding lumen of substantially circular cross-section and a fluid flow channel. A port housing is located at the proximal end of the shaft with the port housing having a main food inlet port, a Y-port and a fluid inlet port. Near the distal end of the tube are an expandable component member and a food outlet port, which port is preferably located at the distal end. The feeding lumen is of a greater diameter than that of the fluid flow channel. The outer surface wall is of a non-circular cross-section. The feeding lumen is of a circular cross-section which permits the passage therethrough of a jejunal tube. The main food inlet port is of a greater diameter than that associated with the Y-port. The method for using this device permits jejunal feeding through a replacement gastrostomy tube without retraumatizing the patient.
