Percutaneous radiologic gastrostomy catheter placement without gastropexy: a co-axial balloon technique and evaluation of safety and efficacy.

Purpose: The purpose of this study is to evaluate the short-term safety and efficacy of a co-axial angioplasty balloon technique for percutaneous radiologic gastrostomy catheter placement (PRG).

Methods: A total of 65 percutaneous radiologic gastrostomy tube placements were performed with the co-axial angioplasty balloon technique from 10/1999 to 1/2014. This included 19 females and 46 males between the ages of 20-83. Without the use of T-fasteners for gastropexy, the gastrostomy tube was placed over a catheter-shaft angioplasty balloon as a co-axial system. The angioplasty balloon was used to sequentially approximate the stomach wall to the abdominal wall, dilate the tract, and was then used as a dilator to aid gastrostomy tube advancement into the gastric lumen. Technical success, complications, and dislodgements were evaluated by means of retrospective review of patient medical records and imaging.

Results: There was no procedural failure in any of the 65 placements. 30-day follow-up was available for 56 patients. 7 patients died within 30 days; none of the deaths were recorded as procedure-related. There was 1 major complication (1.5%) consisting of a colocutaneous fistula. There were 4 minor complications (6.2%). There was no occurrence of bleeding or skin infection while using this technique.

Conclusions: PRG with the co-axial angioplasty-balloon technique is a safe and effective technique for gastrostomy placement.
