In Patients Needing Gastric Tubes, Additional Imaging Gives Better View And Reduces Complications

Additional fluoroscopic and CT views can substantially reduce that occur during percutaneous radiologic gastrostomy, a procedure used for patients who require a gastric tube for nutritional support.

“In a study of 146 patients, we saw a major complications rate of 5.9%,” said Dr. , of SUNY Downstate Medical Center, in Brooklyn, NY and lead author of the study. Major complications included organ injury with hemorrhage and colonic perforation, he said. , such as tube leakage or dislodgement, occurred in 17.6% of patients, he said. “We were concerned with the high rate of complications, and we wanted to eliminate them.”

“Topographic anatomic misjudgment appeared to be the cause for all major complications in this group of patients so we changed our technique to provide us with a better view,” said . In a follow-up study of 29 patients, we added fluoroscopy in oblique projection, cross table lateral fluoroscopy or biplane fluoroscopy, said. “We virtually eliminated the problem of misplacement of gastrostomy catheters,” he said. “By including CT in AP, lateral and oblique projection, we’ve eliminated improper passages of entry-tracts through other organs,” said.

It is important to note that surgical gastrostomy and – two other techniques for insertion of feeding tubes – have even higher rates of complications, said Dr. Lang. Surgical gastrostomy has a reported 74.3% complication rate, while has a reported 42.9% complication rate.
