Fluoroscopic insertion of post-pyloric feeding tubes: success rates and complications

Abstract

Aim: To examine the success and complication rates of radiological placement of post-pyloric feeding tubes, including those inserted with the assistance of a guide-wire.

Materials and methods: Two hundred referrals (156 patients), between the dates of 5 April 2002 and 10 September 2004, were identified retrospectively from computerized records. Subsequently, the radiology reports and patients' notes were reviewed to evaluate the indications for post-pyloric feeding, success of placement, use of a guide-wire, and any complications.

Results: A post-pyloric tube was placed in the distal duodenum/jejunum in 183 (91.5%) patients and in the proximal duodenum or distal stomach in six (3%). A tube could not be inserted in 11 (5.5%) patients, and 51 (25.5%) of the insertions required the use of a guide-wire. Immediate complications were recorded in seven patients (3.5%): vomiting (n=5); hypotension and apnoea requiring naloxone (n=1) and hypoxia requiring endotracheal intubation (n=1).

Conclusion: Radiological placement of post-pyloric feeding tubes has a success rate comparable with endoscopically placed tubes, and it rarely involves significant technique-related complications.
