A dual-tube feeding tube assembly for single-procedure placement inside the body of a patient, the assembly having a tubing unit including a gastric tube and jejunal tube adjacent one another such that the proximal end of the tubing unit is positioned outside the patient's body and the distal end is positioned inside the patient's body. A pointed tip attachment piece on the proximal end of the tubing unit allows the tubing unit to be pulled orally through the patient's esophagus and stomach until the pointed tip attachment piece extends through an abdominal incision. A set of bumpers on opposite sides of the abdomen wall maintain the position of the tubing unit such that the distal end remains inside the body and the proximal end remains outside the body so that medicine, food, and other substances can be supplied to the patient through the tubing unit.
