Abstract

Introduction Long-term percutaneous enteral nutrition forms an important part of treatment for patients with an inability to meet nutrient requirements orally. Radiologically inserted gastrostomy (RIG) is an alternative to the traditionally performed percutaneous endoscopic gastrostomy technique. However, there is marked heterogeneity in the way that RIG is performed. In addition, the role for antibiotic prophylaxis during RIG insertion is not clearly established. This study aimed to assess the safety of RIG insertion using our technique including the role of antibiotics in RIG insertion.

Method Retrospective study over 5 years at a tertiary teaching hospital. Periprocedural or early complications within the first 2 weeks of the procedure were collected and correlated with the use of prophylactic antibiotics.

Results A total of 116 patients met the inclusion criteria. 18-French tube was used in 96.6%. Note that 58.6% of procedures were done with intravenous sedation. Prophylactic 1 g cefazolin was used in 70 patients with 1 case of infection. Procedures were performed without antibiotics in 46 patients with 3 infections, p = 0.20.

There were two major complications (1.7%) consisting of right gastric artery injury requiring embolization and gastric wall injury requiring laparotomy. There were 12 minor complications (10.3%) including 4 cases of infection, 3 of severe pain, 1 of minor bleeding, 2 of early dislodgement, and 2 of leak/bypass of gastric contents around the tube.

Conclusion The technique used for RIG insertion at our institution results in a low complication rate. In addition, this study shows no significant difference in early peristomal infection rate with the use of antibiotic prophylaxis.
