Comparison of fluoroscopy-guided Pull-type percutaneous radiological gastrostomy (Pull-type-PRG) with conventional percutaneous radiological gastrostomy (Push-type-PRG): clinical results in 253 patients

Eur Radiol. 2011 Nov;21(11):2354-61. doi: 10.1007/s00330-011-2194-3. Epub 2011 Jul 9.


Objectives: To analyze the clinical results and complications of fluoroscopy guided internal-external Pull-type percutaneous radiological gastrostomy (Pull-type-PRG) and conventional external-internal percutaneous radiological gastrostomy (Push-type-PRG).

Methods: A total of 253 patients underwent radiological gastrostomy between January 2002 and January 2010. Data were collected retrospectively from radiology reports, Chart review of clinical notes, procedure reports, discharge summaries and subsequent hospital visits. Statistical analysis was performed to compare the two methods for gastrostomy with respect to peri-interventional aspects and clinical results.

Results: 128 patients received the Pull-type-PRG whereas the other 125 patients were served with the Push-type-PRG. Indications for gastrostomy were similar in these two groups. The most frequent indications for the both methods were stenotic oesophageal tumors or head/neck tumors (54.7% in Pull-type-PRG, 68% in Push-type-PRG). Gastrostomy procedures were successful in 98.3% in Pull-type-PRG compared to 92% in Push-type-PRG. There was no procedure-related mortality. Compared to Push-type-PRG, the peri-interventional complication rate was significantly reduced in Pull-type-PRG (14.8% versus 34.4%, P = 0.002).

Conclusions: Compared to the external-internal Push-type-PRG, the internal-external Pull-type-PRG showed a high primary success rate and a decreased incidence of peri-interventional complications.
