Percutaneous radiological gastrostomy: single-puncture double-anchor technique.

ABSTRACT

PURPOSE: We evaluated technical success, safety and effectiveness of percutaneous radiological gastrostomy (PRG) with a modified technique single puncture and double anchor. MATERIALS AND METHODS: From January 2008 to June 2011, 163 patients underwent PRG with a single-puncture double-anchor technique. The stomach was punctured with a 17-gauge Chiba needle, and gastropexy was performed by placing two anchors in the gastric lumen. Finally, a 12-F Wills-Oglesby percutaneous gastrostomy catheter was inserted. Technical success and complications at 30 days were evaluated on the basis of imaging and patients' medical records. RESULTS: PRG was successfully completed in all 163 patients. Only a single puncture was required in all patients. The average PRG procedure time was 9 min. Three patients had major complications haemorrhage (n=2) and pneumoperitoneum (n=1). Ten patients had minor complications tube malfunction/breakage (n=9), and leakage through the insertion site (n=1). Two patients died 30 days after the procedure. CONCLUSIONS: Single-puncture double-anchor PRG is a fast, safe and effective technique.
