IWR1 The aims of the present study were to analyze and compare the clinical outcome and long term efficacy of percutaneous. Methods: We retrospectively reviewed the 138 patients who underwent percutaneous gastrostomy. The patients were classified into PEG and PRG group. The indication, complication

and tube patency were compared between groups. Results: PEG was performed in 90 patients and the other 48 patients were underwent PRG. Mean age was 60.0 ± 17.5 years and male to female ratio PD0325901 mouse was 102: 36. The indications were mostly unable to eat (67.4%), followed by recurrent aspiration (18.1%) and esophageal stricture (10.1%). Among 48 patients in PRG group, 14 cases (29.2%) were due to the failure of scope passage. Immediate complication occurred in 5 cases. Wound infection was the most common immediate complication. One case (0.7%) of bleeding at gastrostomy site in PEG groups and one case (0.7%) of stomal leakage in PRG group were noted. Delayed complication occurred in 8.0% at 398 ± 546.9 days and insertion site infection was the most common complication. The patency was longer in PEG group (227.0 ± 50.1 days vs. 132.0 ± 32.8 Acyl CoA dehydrogenase days, p = 0.012). The associated factors with poor patency were presence of esophageal stricture and malignancy.

Conclusion: Both PEG and PRG are relatively safe procedure. Moreover, PRG can be substituted for PEG in patients unable to pass the scope or in over-weighted patients. The presence of stricture and malignancy of esophagus were predictors of the poor tube patency.

The aim of this study was to determine the efficacy of PA for reducing the infectious complications and the potential risk factors responsible for the infectious complications after stent insertion.
